[DUG]: Ellipsis truncation
Does anybody know of a good way of shortening a capition shown on screen to X pixels and putting an '...' at the end? I seem to recall that there might be an API call that'll do it, but I can't remember it's name.

RE: [DUG]: Ellipsis truncation
Cool, I think that is what I was trying to remember. Might have a write a small funciton that finds out how long the string will be when rendered and slowly shrinking it till it fits with an '...' at the end. Nahum.

That will be about 3 times or more slower than length(a) - given that
A is a string.
Delphi's handling of single characters in a string is rather
horrible. It generally creates a temporary long string of 1 character
copies from the original string and then does the compare - Yuck!!
Plus of course you have just added a compiler generated try - finally
around you block of code.

The term for this is cloning an object.
There is no built in way of doing this in Delphi, and there are
issues involved in any cloning operation; e.g. are you interested in
a shallow clone (just the one object), or a deep clone (your one
object, and all objects to which it refers)?
Probably a google newsgroup search on Delphi+cloning+objects might
give you a few ideas on how to progress...
If your object inherits from TComponent the following code will clone
a component. I have used it to clone TButtons and few other simple
visual components successfully.
unit Cloner;
interface
uses
SysUtils, Classes, Controls;
function Replicate(C: TComponent): TComponent;
implementation
procedure CloneComponent(C1: TComponent; C2: TComponent); //
// This procedure clones the properties of C1 and writes them to C2.
// C1 and C2 must be of the same type. Use it for components that do
// not have an Assign method. //
var
theStream: TMemoryStream;
tmpS: string;
begin
if C1.ClassType C2.ClassType then
raise EComponentError.Create('Object types are incompatible');
if C1 is TControl then
TControl(C2).Parent := TWinControl(C1).Parent;
theStream := TMemoryStream.Create; // Create the memory stream.
with theStream do try
tmpS:= C1.Name;
C1.Name := EmptyStr;
WriteComponent(C1);// Write C1 properties to stream
C1.Name := tmpS; Seek(0, soFromBeginning); // Position to
beginning of stream. ReadComponent(C2); // read

// IAC, free stream. end; end;
function Replicate(C: TComponent): TComponent;

RE: [DUG]: Copying an Object
Nope, it means that its encapsulated (or whatever the word is and how its
spelt) and only revealing stuff that needs to be revealed - and it might
only be in the public section rather than the published section; data hiding
and all that. One of the three corners to good OO design (hurrah) -
inheritance and polymorphism being the others :o)
A clone is an exact copy, not a partial one. The assign concept works well
for me.

If you need to copy the internals of an object then it would
reflect badly on your objects design wouldn't it?

The only problem here being that just the published properties will
be cloned, no internal state variables.

The term for this is cloning an object.
There is no built in way of doing this in Delphi, and there are
issues involved in any cloning operation; e.g. are you interested
in a shallow clone (just the one object), or a deep clone (your one
object, and all objects to which it refers)?
Probably a google newsgroup search on Delphi+cloning+objects might
give you a few ideas on how to progress...
If your object inherits from TComponent the following code will
clone a component. I have used it to clone TButtons and few other
simple visual components successfully.
unit Cloner;
interface
uses
SysUtils, Classes, Controls;
function Replicate(C: TComponent): TComponent;
implementation
procedure CloneComponent(C1: TComponent; C2: TComponent); //
// This procedure clones the properties of C1 and writes them to C2.
// C1 and C2 must be of the same type. Use it for components that
do // not have an Assign method. //
var
theStream: TMemoryStream;
tmpS: string;
begin
if C1.ClassType C2.ClassType then
raise EComponentError.Create('Object types are incompatible');
if C1 is TControl then
TControl(C2).Parent := TWinControl(C1).Parent;
theStream := TMemoryStream.Create; // Create the memory stream.
with theStream do try
tmpS:= C1.Name;
C1.Name := EmptyStr;
WriteComponent(C1);// Write C1 properties to stream
C1.Name := tmpS; Seek(0, soFromBeginning); // Position to
beginning of stream. ReadComponent(C2); // read
properties from stream into C2 finally Free;
// IAC, free stream. end; end;
function Replicate(C: TComponent): TComponent;
//
// This function replicates component C and returns
// a new component whose type and properties match
// those of C.
//
begin
Result := TComponentClass(C.ClassType).Create(C.Owner); // Create
component } CloneComponent(C, Result);
// Clone it } end;
end.

RE: [DUG]: Delphi 7 comments...
The XP Theme stuff in Delphi 7 is actually a freeware component available from this [http://www.lischke-online.de/] site. Check out the news item about is a bit down the main page. Aug 10 2002, 11:44 PM, Windows Xp Theme Manager And Delphi 7 I am very proud to tell you that Borland decided to include my Windows XP theme services as integral part of the VCL into Delphi 7. This means you don't need the XP Theme Manager anymore for Delphi 7 and higher. A new unit called Themes.pas contains now all relevant stuff for XP theming. The components themselves are available directly from here [http://www.delphi-gems.com/ThemeManager.html]. I placed an order for Delphi 7 Pro Upgrade thru my normal channels as soon as it was announced, but actually cancelled it after going to the Christchurch launch. Comments made by the presenter were rather... disappointing we shall say, regarding his views towards OO, UML, RAD development and business rules with respect to Delphi. A bit of real world experience (or at least the same world as mine) lacking there I think. Shame. I'll continue writting specs before coding thankyou. Just my pound of 2 cents. Nahum Wild Software Innovator Game Designer Realism [via PayGlobal today] [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] wrote on Installed it last night and all I can say is that I hope there are a heap of changes 'under the hood' because there are hardly any apparent on the surface. Except them messing with the options dialogs again. There looks to me like it is a release to get XP compatiblity included. I only have the PRO version so the enterprise version might have more changes. One thing that I found good was a Development version of Borlands application server (have it run for 72 hours continuously). It comes with heaps of cd's if that gets you going, including: D7 Pro, D7 .NET pre-release, D7 companion, Kylix 3 Pro, Borland Enterprise Server CD with all versions.

[DUG]: D6 multi-monitor development don't work
Morning all, I've moved to using Delphi 6 (from D5) and the IDE does not remember correctly the position and size of the main delphi window and the editor window. I have the main window spread across two side-by-side monitors with the component palette located on the secondary screen and everything else on the primary. I do form design on the secordary monitor and code editing on the primary. D5 would remember this without problems and I could flick between saved desktop layouts without any problems. Quite handy because I have a different debug layout. Delphi 6 is another question though. Whenever I change layouts, or even just run delphi, the main window gets resized to fit only on the primary monitor and the code editor is resized to full screen - primary monitor only. This as you could imagine is very annoying and brings back memories of the first version of delphi 4. (An even numbered version of delphi!) Has anyone else experienced this problem? Is anyone else using multi-monitor not experiencing this problem? To answer the question thats bound to be asked, I'm using a Matrox G400 with 32mb of ram with their latest drivers to get multi-monitor. But it all worked fine under D5, the only change to my system has been installing D6 - which has problems. :-( I still have D5 on my system and it is working without problems.

FOR IMMEDIATE RELEASE BORLAND UNVEILS INDUSTRY'S FIRST RAD WEB SERVICES DEVELOPMENT PLATFORM Borland. DelphiT 6 Introduces New RAD Platform For The Rapid Creation Of Web Services Using Latest Industry Standards SCOTTS VALLEY, Calif. - May 8, 2001 - Borland Software Corporation (Nasdaq NM: BORL), a leader in e-business implementation platforms, today announced the availability of Borland. DelphiT 6, the new version of its rapid application development (RAD) environment for Windows.. As the first RAD tool to help developers easily use and create industry standard Web Services, Delphi 6 enables the rapid development and deployment of applications using XML- and SOAP-based Web Services technologies. Delphi 6 Web Services and XML technologies speed e-business by allowing companies to share and exchange application data, such as information about a business, transaction or supplier, over the Internet with minimal human intervention. Delphi 6 is the only RAD environment that fully supports all major emerging industry standards: XML, SOAP, WSDL, and XSL; in turn, supporting emerging Web Services based vendor platforms such as Microsoft. .Net and BizTalk, and from Sun Microsystems. ONE, while providing the scalability and reliability that enterprise and Web developers require. The adoption of Web Services is at a crossroads, said Evan Quinn, director of application strategies for Hurwitz Group, an analyst, research, and consulting firm. Right now, individual and corporate developers need the right tools to make Web Services applications powerful, yet easy to design. With Delphi 6, Borland is responding to this critical industry need. The new Delphi framework includes BizSnapT, WebSnapT and DataSnapT, which will help users build server-side and client-side applications that support Web Services specifications through a fully integrated set of Web Service enabled visuals tool, advanced compiler technology and re-usable software components. Delphi 6 is designed to enable faster time-to-market by simplifying business-to-business integration. Web Services is the next step in application development on the Internet and developers are under pressure to quickly move business applications to open standards so even though two companies have different IT infrastructure, they can conduct e-business together, said Simon Thornhill, vice president and general manager of Borland's RAD products. Delphi 6 enables any Enterprise to quickly move into the future of e-business application development with Web Services without abandoning past methodologies, skills and source code. Borland Delphi 6 new product features include: * BizSnap Web Services RAD development platform simplifies business-to-business integration by easily creating XML/SOAP Web Services and connections. * WebSnap is a component-based Web application development framework that supports leading Web Application Servers, including ApacheT, Netscape. and Microsoft Internet Information Services (IIS). * DataSnap allows customers to build high-performance, Web Service-enabled middleware that enables any client application or service to easily connect with any major database, such as Oracle., MS-SQL Server, Informix., IBM. DB2., Sybase. and InterBase., through industry standard Web Services and XML, DCOM, or CORBA.. In addition, when paired with Borland KylixT, the first native RAD environment for the Linux. operating system (OS), Delphi 6 users can build single-source applications for both Windows and Linux, which opens new opportunities and increases the potential return on development investments. Delphi 6 is scheduled to be available this month in three editions -- Enterprise, Professional and Personal. About Borland .

RE: [DUG]: How to Do This
Well after a few minutes of finger bluring action last night I got it

object;
TBasicMath = class(TObject)
private
protected
public
class function Execute(const sOperation : string; const iVar1, iVar2 :
integer) : integer;
published
function Add(const iVar1, iVar2 : integer) : integer;
function Subtract(const iVar1, iVar2 : integer) : integer;
function Multiply(const iVar1, iVar2 : integer) : integer;
function Divide(const iVar1, iVar2 : integer) : integer;
end;
implementation
{$R *.DFM}
class function TBasicMath.Execute(const sOperation : string; const iVar1,
iVar2 : integer) : integer;
var
ABasicMath : TBasicMath;
AMathOp : TMathOperation;
AMathMethod : TMethod;
begin
ABasicMath := TBasicMath.Create;
try
AMathMethod.Code := ABasicMath.MethodAddress(sOperation);
AMathMethod.Data := ABasicMath;
AMathOp := TMathOperation(AMathMethod);
assert(assigned(AMathOp));
Result := AMathOp(iVar1, iVar2)
finally
ABasicMath.Free;
end;
end;
function TBasicMath.Add(const iVar1, iVar2 : integer) : integer;
begin
Result := iVar1 + iVar2;
end;
function TBasicMath.Subtract(const iVar1, iVar2 : integer) : integer;
begin
Result := iVar1 - iVar2;
end;
function TBasicMath.Multiply(const iVar1, iVar2 : integer) : integer;
begin
Result := iVar1 * iVar2;
end;
function TBasicMath.Divide(const iVar1, iVar2 : integer) : integer;
begin
Result := iVar1 div iVar2;
end;
{-}
The usage for it would be something like this -
Edit1.Text := IntToStr(TBasicMath.Execute('Divide', 81, 9));
Hopefully its useful for someone.

You can do it if the methods are published.
TObject.MethodAddress takes a
string and returns a pointer to the published method of that
name, or nil if
no method with the passed name exists.

Subject: [DUG]: How to Do This
Hi all.
Some time back (months I think) I asked if there was a way to
call a function or procedure based on its name dynamically,
I.e the functions might me called
Function1
function2
Function_test
etc.
In VB you can go CallByName("Function1") and it will call the
function, anf I want/need to do this in Delphi.
Like I say,someone said that this can be done in some form,
but I was wondering how they do it etc. and IF they can show
me a bit fo code hwo its done.
Thanks, Jeremy Coulter

RE: [DUG]: What I Am Doing.
To all those who are wondering. Who can programme? Who has heard of Youden? How about Orr? And Jackson? Have you heard the expression 'A picture paint a thousands words'? Well - what I am doing is writing a complier that will produce code from structure diagrams like these guys came up with. What we have, so far, is an extension of the basic structured diagram and most of these extensions come are because we can have the diagrams dynamic because the user (programmer) will draw the structured diagram on the computer. This compiler will, for now, produce Pascal source code but the actual code is not all that important and it should be easy to extend it to produce any source of object code. The user will place 'nodes' on the 'page' and connect these 'nodes' to other 'nodes'. There are different 'nodes' for different programming constructs. The user will then 'run' this code. There will be no need to learn language syntax etc - the user will just fill-in forms with the required information - eg, a for loop will require a starting condition and an increment and a block of some actions. It will be impossible (IN THEORY) to write bad code. This is a project that has been going for a few years now and I did a paper on it for my undergrad degree. I have decided to do a masters degree and work on this for my thesis which is one year full time study with a further year of study in more general stuff to do with computer science. After that I plan to do (well, this is the theory) a PhD in the area - that should take another three years. At the end of all this I/we/someone should have a working version of a full general programming language that requires no code to be written by programmers, only diagrams to be produced. I would like to thank everyone here for their past and future help (cos I know I am going to need it). So far you guys have been great. Keep up the good work. I have a strong programming background but have never written in Pascal before and have never done any OO stuff except at uni (and that doesn't count). Chrissy.

No OO, you don't know what your missing out on! You could link your structure diagram code generator to a third party UML design tool such as Object Domain or Model Maker. Where they produced the class strucure and general program behaviour source and you generated the code for each method. That in theory would work really nicely.

RE: [DUG]: Lazarus vs Kylix
Corey Murtagh wrote : I mean from the screen dumps, the source code is practically identical even to having the component names the same etc. well, what else ya gonna call a button? TWidgetThingThatsClickedOnAndLooksLikeAButton ;-) Point(s) taken, but how if you check out their status page: http://www.lazarus.freepascal.org/status.php3?language=english It's kind of obvious that they're converting the VCL for Lazarus. They have a list of all the VCL classes that they want to translate, and as they're writing it in Delphi-compatible OP I somehow doubt that it's all clean-roomed. In fact I'd be very surprised if you couldn't find a fair amount of the Borland/Inprise VCL code in there somewhere. Why would you want to copy something without improving upon the original idea? If the lazarus project aims to duplicate delphi exactly, warts and all, then there is no point in the project and everyone may as well go and buy a copy. This would be the only way that copying "fair" amounts of borland VCL code across could work. But if Lazarus, say, fixes the warts and adds a tweak here, an enhancement there and tries not to touch windows then there is no way that any significant amounts of borland VCL code would even work. It could be used as a guide though. Now, I'm not saying I'd be suprised if they did use borland VCL code, I'm just saying that it would be a silly idea to do so. The whole 'holding your self back by nailing your foot to the floor' concept comes to mind. Just my two cents worth at 2:54 in the morning as I hear The Press being delivered.

[DUG]: TBits - array of bits
I'm wanting to create a 2d array of bits where the less memory used to store the array the better. A boolean array is out of the question as a boolean uses up a byte. So I looked in the D5 help and found the TBits class. It is accessed as a boolean but looking at its source code reveals that its coded in assembler. Which I can't read. So my question is - does TBits store everything at the bit level or at the byte level? Alternatively does anyone know of a different approach to doing this where memory footprint it critical with access speed coming a close second?

Cool bananas. Thanks for the helpfull replies. I guess that if I had looked more closely at the SetSize method I should have figured it out. :) The array will be filled with about 60% true values so it makes sense to store the whole lot. But I have used the concept of just recording where the true values are else where to good effect.

Are the arrays large with only a few true values? If so a sparse array approach may be better. IE only allocate space to store a true value. You will have to allocate space to tell you which values you have and map the real index to the storage index, but if the number of values to be stored are very small w.r.t. the overall size of the array you may end up with a saving.

You missed the 'class' part of the class procedure, it should be as below with the class reference at the very begining of the statement. Good idea though, you get rid of the object trying to free itself within its own constructor which sounds a bit dodgy. :) class procedure TMyGadget.CreateBriefly; var it:TMyGadget; begin it:=nil; try it:=TMyGadget.Create(); //call the protected constructor finally it.free; end; end; Cheers, Nahum -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Nello Sestini Sent: Thursday, October 26, 2000 21:50 To: Multiple recipients of list delphi Subject: Re: [DUG]: Free inside Create a Delphi constructor (unlike those in C++) doesn't get called implicitly (like for local variables or for args passed by value) This means that to create one of these things you'll have to explicitly call TMyGadget.Create (or use new ). So how about writing a class function CreateBriefly that isn't a constructor and call that instead.Make CreateBriefly public and make the real Create constructor protected. CreateBriefly will look like something like: procedure TMyGadget.CreateBriefly; var it:TMyGadget; begin it:=nil; try it:=TMyGadget.Create(); //call the protected constructor finally it.free; end; end; then in all the places you currently call Create you change these to calls to CreateBriefly.

RE: [DUG]: Multiple Inheritance?
If I understand the dilemma correctly an interface could be used, as per the example code below. They key to it is the implements directive. (look up the "implements, interfaces" in the delphi help. Its only available in D4 inwards though.) - ISharedCode = interface(IUnknown) [GUID] function DoSomething : integer; end; TSharedCode = class(TInterfacedObject, ISharedCode) public function DoSomething : integer; end; TSomeOtherClass = class(TComponent, iSharedCode) private fSharedCode : ISharedCode; public constructor Create(AOwner: TComponent); override; property SharedCode : ISharedCode read fSharedCode impliments ISharedCode; end; function TSharedCode.DoSomething : integer; begin // does something end; constructor TSomeOtherClass.Create(AOwner: TComponent); begin inherited Create(AOwner); fSharedCode := TSharedCode.Create; end; - This means that you can call the following - ASomeOtherClass.DoSomething - which calls the appropriate method from the instance of TSharedCode within the TSomeOtherClass instance directly without having to have stub methods. NOTE: This is how I believe it works, I've not had a situation where I've had to use it yet. After reading the help I believe that the above code should work. Hope that helps.

It is where I start whenever I need to build something. The only time I go into Delphi now is for Building forms and for implementing the bodies of methods. Good Things: Tight integration with Delphi. I've only once had anything go wrong with keeping the source and the model in sync and that was an error on my part and easy to fix. Open Architecture for creating plugins (I've done three now - they're quite easy) Supports Class, Sequence Diagrams, Unit Dependency Diagrams, and (comming soon) State Diagrams Mailing list which is read and contributed to by the MM5 developer Parameterised Code templates Implements Patterns on your classes at the click of a button Continually being maintained and improved based upon discussion in the mailing list Unit Difference Tool! Documentation for most things. It is CHEEP compared to other design tools. Bad Things: Can't export to anything except Windows Meta Files Can't handle overloading Can't handle conditional defines Doesn't know about IDL Documentation for writing plugin experts is a little on the sparse side (but examples are provided) I don't get to use CodeRush as often as I used to. Stability: I've not had any major problems with it. The occassional small bug (as with any software) but certainly stable. I've used Rose and the Delphi Link for Rose and they are painful compared with MM5. If you've ever used TogetherJ, then that is what it is like as far as having the code and the model grow together.

RE: [DUG]: Loading forms from dynamic DLL's and enbedding them
I think that I have experienced similiar behaviour when doing this, but not from a DLL though. My problem was that the form to be imbeded in the panel was initially bigger than the panel it was to go on. For same bizzar reason the aligning of the form did not work properly and I got the visual behaviour that you discribe. I made the form smaller than the panel at design time and that fixed it. The version of Delphi that I was using at the time may also have been a factor.

I have a DLL that includes a form that I want to display embedded into a shell application. The DLL is dynamically loaded by the shell which then calls a startup procedure that is exported by the DLL. To the startup procedure it passes a TPanel. When the embedded form draws itself inside the panel, it get's confused about it's size and the bottom and right of the form is lost outside of the containing panel. I have created a small demo app and dll that demonstrates this which I can provide on request. Has anyone else done this sort of thing succesfully cause this is driving me nuts and I need it fixed, like, last month. __ __ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com --- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz --- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz
RE: [DUG]: Dbf corruption
Wow, that brings back some old memories. I now remember that I have encountered this problem before and I ended up writing some code that changed that byte to something else, if problems were encountered with DBF files, then reindexing them. I can't remember which byte or what I changed it too. But I do remember that I did it and it worked. Nahum -Original Message- From: Simon Mahony [mailto:[EMAIL PROTECTED]] Sent: Monday, 8 May 2000 11:23 To: Multiple recipients of list delphi Subject: Re: [DUG]: Dbf corruption Does that work the other way, a dbf created by Database Desktop not openable in Access as I think I have seen that before? I will check whether it was created in Foxpro but the app is a DOS one, did Foxpro for 3.1 exist? Foxpro has been around since the days of DOS 3.3 (or thereabouts - ie: pre Windows) so it could easily be an old version. The DBase header record has a single byte in it (somewhere in the first few bytes from memory) which indicates the application which created it and the version. This causes no end of problems because few of the applications that read these files are prepared to accept more than one or two of these varients even though there's no difference between the dbf file structures themselves. Almost all the variations in the Dbase system revolve around index and memo files, both of which are external to the dbf file. For some reason however, the creators of other DB products make a point of rejecting dbf's that have indexes they can't read instead of saying "sure, we can read your data, but we'll have to create our own index for it - Ok ?" (which is about all the problem boils down to). The BDE won't read dbfs created in Clipper for example, but it (and everything else) will hapily read dbfs written in Dbase 3. And in almost every case, the difference is a single byte in the file header. Go figure. If you get really stuck, I have all the file structure stuff in a couple of books at home.
