Re: [Lazarus] Capturing the output from a command using TPorcess
2015-07-20 21:41 GMT+02:00 Richard Mace richard.m...@gmail.com: Hi All, I hope this question is going to make sense. I am trying to obtain the MAC Address of a remote PC, using psexec \\pcname and running the command ipconfig /all. If I run the psexec command from my machine via a command prompt, ipconfig /all is successfully run on the remote machine, and I can see it's MAC address, however, if I run it via TProcess, in Lazarus, the output I get from TProcess is the output from psexec (successfully run and exited with error code 0) rather than the output from ipconfig. How can I code TProcess, so that it shows me the output from the ipconfig /all command instead? Hello, This is not exactly what you asked for, but you could simply redirect the output with something like ipconfig /all ipconfig..txt then read the contents of ipconfig.txt (or whatever name you gave to the output file). You must take care where you put the output file, though: you must have the rights to write in that folder. Of course my solution is only a quick trick, the answer to your question would be much cleaner and much more interesting. -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] OOP - where do you start?
2015-06-26 13:30 GMT+02:00 Graeme Geldenhuys mailingli...@geldenhuys.co.uk : Hi, Hello, Last night I was working on a relatively new project. This got me thinking... How do others tackle such a task? So here is my question: When faced with a new database related project, where do you start? Do you first design the database schema, then build the BOM (Business Objects) accordingly? Or, do you first design the BOM, then design the database schema to fit. Personally, most of my project were started by first creating the database schema. Don't ask me why, that is just what I did. Maybe it was because many of the tools I use, can write much of the boiler plate code for me, and they do that by querying a database structure. But I've been thinking that with my next project, I'm going to start with the BOM first, and see how it goes. I'm assuming the end result should be the same, no matter which part I tackled first. What's your thoughts? IMO, it depends on the complexity of the project. In simple projects (a few tables), usually the BOM maps exactly to the database, so I do both at the same time. But in complex projects, BOM can be significantly different from the database structure. For example, the BOM could include things which would actually map to aggregated views. Usually I first design the BOM according to the requirements, then I rework the database structure, including for example things which were not requested but which I feel will be useful later (timestamps, history tables, intermediate calculation steps, future developments...). One classical example: if I am asked to create a table with name and address, I actually create a table with the name and a separate table with the addresses, so that when (this always happens) the client discovers that people have more than one address, the database structure is ready, but also the code using that structure is ready too, or at least the modifications to that code are going to be simpler. In my example, the BOM still has the address included in the same object as the name, and the UI can behave as if this was physically true. In a way, separating BOM from physical structure brings the same kind of advantages that structured programming does. Just as I can look at a piece of code from a higher level or right at the deepest code in the deepest routine, depending on my needs, I can look at the data from a wide point (usually using views or complex queries) or break the data in smaller parts and look at the physical data directly in the tables. -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Here are my results using NVDA 2014.4 on Windows 7 64 bits Properties : NVDA doesn't announce the property names in the Object inspector. This is not related to the new checkboxes, but it may influence how corrections are prioritized. Because the property names are not told (sorry, I can't decide how this should be said in English: would one say something (name, property, label...) is enunciated, told, said, announced...?) TCheckBoxThemed : design mode : NVDA won't say the control name in the form editor, whether I select it by clicking on it or by tabulating to it. Same for a standard TCheckbox. Afterthought; Because the Objecct inspector does not currently tell the property names, I guess most blind users wouldn't use a form designer but would edit directly the lfm file with a text editor. But this is only my guess, I don't know any blind developer who uses a IDE, although I am sure there are lots of them. run mode : NVDA tells the control name, but it won't say if it is checked or not. When pressing the space bar, NVDA says only space, and does not react at all when clicking on the TCheckboxThemed. This works perfectly with a TCheckBox. I am sorry to conclude that TCheckboxThemed is currently unusable for a blind user. I looked a little around to try to find how TCheckbox manages to be properly recognized by NVDA.

See https://en.wikipedia.org/wiki/Screen_reader . Screen readers allow blind or visually impaired users to use computers. In order to work, screen readers must know what a control is, in order to be able to speak or display in braille what is going on. In our specific situation, a screen reader would need to know that TCheckBoxThemed is a checkbox. I guess that the screen reader wouldn't need to be able to distinguish the new TCheckBoxThemed from a standard checkbox, pixel-level alignment considerations are usually not very significant to blind users. I see 2 ways to achieve this: - either TCheckBoxThemed is derived the standard Windows checkbox in such a way that the screen reader will directly see and interpret the standard control - or TCheckBoxThemed is a brand new control created from scratch, which means a blind user would have to teach his screen reader that this new control is a check box (if the screen reader offers such a functionality). Obviously, this second solution isn't as good as the first one. I don't know how screen-reader-friendly is the LCL's TCheckbox, using it to derive TCheckBoxThemed could be a good solution or not. I don't have or use any screen reader software, but I know at least one (NVDA) which I could install to check on Windows. Because screen readers use quite different methods for gathering information, any tests I would do with NVDA would not necessarily apply to other software or OS. -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Frederic, you apparently don't know how LCL components work. They bind into native widgets. In case of Windows it means Windows GUI controls. It means the screen reader support and all comes as an automatic bonus. That's how it is supposed to work.

Yes, of course, I forgot about that :-P A custom drawn widget library must implement screen reader support by itself. Now Object Inspector uses LCL's TCheckbox on the selected row.

In your problem, from your description, I thought the click triggered the polyline control while you would have wanted it to be handled by the TImage which is behind the polyline. In a way, your problem is not enough transparency (in terms of who gets to handle the click event) while the bugtracker bug is too much transparency. Or did I misunderstand you? 2014-11-22 10:01 GMT+01:00 Fabio Luis Girardi fluisgira...@gmail.com: Here is it: http://bugs.freepascal.org/view.php?id=20381 2014-11-21 22:24 GMT-02:00 Fabio Luis Girardi fluisgira...@gmail.com: I found this bug on bug tracker.

2014-11-20 14:28 GMT+01:00 Juha Manninen juha.mannine...@gmail.com: If 3d effect is needed as Frederic wrote, it can be added. My point of view may be old school :-) But I feel that controls should in some way visually hint if they are editable or not. In software which ignore this, the only way to check if a control is editable or not is to click on it. And sometimes clicking on a control can have irreversible consequences. In old Windows versions, this was achieved using 2D/3D, but newer versions of Windows (I have not checked the Microsoft recommendations for years) could use another clue (rounded/square angles, color...). Anyhow, Sandro's design definitely suggests to me that the checkbox is non-editable. -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] PScanner tkComment token type
Hello,
I am starting to use fpprofiler. Because I did not know what parameters
should be sent to fpc, I decided to use fppinsert. At least one type of
instrumented code fails to compile:
// some code { some comment }
is wrongly changed into
{ some code { some comment } }
which does not compile.
AFAICS the issue comes from the fact that PScanner only has the tkComment
type, so that when fppinsert tries to rebuild the code, it has no way to
know if it should use '//' or '{ }'.
Of course, I can't simply replace tkComment with 2 new distinct types,
there is probably some other code somewhere, not even in the Lazarus
repository, which uses the current set of token types.
I see at least 3 ways to solve my issue
1 - change fppinsert so that if it finds a bracket in the token, it should
use '//' - I don't like much this solution
2 - use a flag in TPascalScanner (something like CommentType) allowing to
know the type of comment if needed
3 - add 2 types tkCommentSlash and tkCommentBrackets into TToken plus an
option to TPOptions so that the calling code could choose to use the simple
tkComment or the more specific tkCommentSlash and tkCommentBrackets
I like the third method best, but I may be missing some drawbacks in these
options, so what would be the preferred way to do it? Maybe a fourth idea?

It's just you can't use *default* for a property if the set's base has more than 32 values. This is from the Delphi manual (but I'm sure it also applies to FPC): quote The default and nodefault directives are supported only for ordinal types and for set types, *provided the upper and lower bounds of the set's base type have ordinal values between 0 and 31;* /quote Source: http://docwiki.embarcadero.com/RADStudio/XE6/en/Properties So the error message is not misleading at all ;) quote Error: Property can’t have a default value Set properties or indexed properties cannot have a default value. /quote This may be me misunderstanding English, but I feel that it is misleading: To me, Set properties cannot have a default value means that even a set with 2 elements could not have a default value. -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

IMO it is just another option as all the others so it should be put below these other options.

It would go either at the extreme right, or at the bottom, moving nearby button right or up because of anchoring): http://www.bononiadocta.it/Lazarus/Dialogues/Dialogues.png I've put in the image also a localized version, to see what it looks like when strings become much longer. I'd choose option 2 because bottom line risks to become crowded if the help button is added, but I'd like to hear other opinions. Giuliano I believe there is another difference in your layouts: the width of the input fields is different, so that the screen copies are misleading, if the input zones had the same width, the version with buttons at the right would be always wider than the version with buttons at the bottom. I prefer putting the buttons at the bottom because of this: it either allows to have a window less wide (I prefer to have this dialog high than wide because I feel it has less chances of getting in the way) or it allows to make the input zone wider, which is nice when inputting large search strings.

[Lazarus] Adding shapes to TShape
Hello, For a game, I need to be able to draw geometric shapes. TShape is perfect except for one missing feature: TShape only draws triangles pointing up, and I need also triangles pointing left, right and down. My first reaction was to create a derived class, and try to somehow add the missing shapes by overriding TShape.Paint and in the overriding method just handle the new shapes. But TShape is designed in such a way that I can't figure out how to do it. Then I thought that I'd create a derived class but that this class Paint method would draw all the possible shapes (including the 3 new ones) and that for that I'd override the Paint method with a modified implementation of TShape.Paint. Much less clean, not really oo-ish, but it should at least work. Should, because when I tried this, I discovered that it would be much more difficult that I had hoped, so that I decided to stop trying and ask here first. Does anybody have a good suggestion about how to handle this? Should I forget about deriving TShape and should I directly modify TShape's code? -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] Convert does not remove WinTypes from uses
Hello, When converting from Delphi using 1.2 RC1 and trunk, the reference to WinTypes in the uses clause is not removed. I checked, in my unit replacement list, I see WinTypes - LCLIntf, LCLType, LMessages and the unit replacement mode is set to Automatic, so that I guess references to WinTypes should disappear.

Maybe because these modes could be used to ensure that the developer is able to switch back to TP/BP or Delphi. If these modes accepted features which TP/BP or Delphi don't understand, switching back would become difficult. Or you could create a source file which you want to be compatible with FPC and with TP.

[Lazarus] 1.2RC1, Incompatible type and overload
Hello,
I posted this on the forum, but maybe the forum is not the best place, so I
post it here too.
I have an Incompatible type error which I can't figure out
program DominoMo;
{$MODE Delphi}
uses
Globals in 'GLOBALS.PAS',
Parametr in 'PARAMETR.PAS';
begin
end.
unit GLOBALS ;
{$MODE Delphi}
interface
uses Laz2_Dom, Laz_XmlRead, Laz_XmlWrite ;
const XML_FILE_NAME = 'DominoMot.xml' ;
var XmlWordLists : TXmlDocument ;
implementation
initialization
{16} ReadXmlFile (XmlWordLists, XML_FILE_NAME)
end.
unit PARAMETR ;
{$MODE Delphi}
interface
uses SysUtils, XmlWrite, GLOBALS;
implementation
procedure InitAndShowModal ;
begin
{13} //WriteXmlFile (XmlWordLists, ChangeFileExt (ParamStr (0), '.xml'))
end ;
end.
Using Lazarus 1.2RC1, I get: PARAMETR.PAS(13,69) Error: Incompatible type
for arg no. 2: Got AnsiString, expected TStream
If I comment out line 16, the project compiles OK.
If I put my cursor on ReadXmlFile and press Alt+Up, the editor jumps to the
correct overloaded version
If I put my cursor on WriteXmlFile and press Alt+Up, the editor skips the
string version and jumps to the stream version
Using Lazarus 1.0.14, I get: GLOBALS.PAS(16,43) Error: Incompatible type
for arg no. 2: Got Constant String, expected TStream
If I comment out line 16, the compiler stops on the same error as for 1.2RC1
If I put my cursor on ReadXmlFile and press Alt+Up, the editor skips the
string version and jumps to the stream version
If I put my cursor on WriteXmlFile and press Alt+Up, the editor skips the
string version and jumps to the stream version
I can't figure any of those errors:
None should occur as far as I can see, as ReadXMLFile and WriteXMLFile both
have overloaded versions which take an ansistring for second parameter.
Is this a bug or am I missing something?

I'm trying something like (just the minimum code, but I can give the

XmlConfig1.SetValue ('/L8', 'dd') ;

end;
(No, it does not make any sense, just me trying to figure out how it works.)
And here is the result:
?xml version=1.0 encoding=utf-8?
CONFIG L8=dd
CONFIG L5=xx/
L1 L2=cc L3=bb/
/CONFIG
The only thing which worked as I wanted is that SetValue ('/L1/L2', 'aa')
is overwritten by SetValue ('/L1/L2', 'cc')
- How do I create third level keys? (or is XmlConfig able to do more than 2
levels?)
- Why does XmlConfig create L2, L3 and L5 as attributes (/ usually is a
level separator, is it not) ?
- More generally, is XmlConfig suited to do more than a simple list (which
would be even less than a .ini can do)?

Interesting enough, the error as reported from Windows (SysErrorMessage(GetLastError)) reports that Windows is unable to find the path specified. I have even tried renaming the file so that it is shorter (within the full path) but I am unable to do that as Windows complains of the same error message. It lookis like it is a temeporay internet file that explorer has created (if that helps) Any ideas? Lazarus 1.2 RC1 Windows Server 2003 This is a pretty frequent Windows issue. IIRC, you have several options: 1: try to delete the file in a DOS shell using short names (for example replacing My Documents with mydocu~1). This is the best option as it avoids changing anything in your system. But it may not work because even the shortened path may be too long. 2+: see all the options form http://support.microsoft.com/kb/320081 , but I'd use solution 3 before solution 2 if the directory where your file is stored is installed by some software (as is suggested by your mention of temporary internet file.

This is where I edit the files with Notepad++ in order to remove parts of code before copying them to the next folder. d:\Delphi\Lazarus_Tests\Memo1_bak\$ contains the files (units) which I have removed from the original source. - d:\Delphi\Lazarus_Tests\Memo1 is the conversion folder, where I copy the files from above and where the application I ask Lazarus to convert is. During one of the code cleaning iterations, I hadn't cleaned properly Memo1_bak so that the uses still contained a reference to a unit which I thought I had removed from everywhere. I had removed the unit source. My new issue is that the converter found the unit in d:\Delphi\Lazarus_Tests\Memo1_bak\$ and converted it! As you can see, my source does not contain any reference to Memo1_bak, I never opened any file in d:\Delphi\Lazarus_Tests\Memo1_bak nor d:\Delphi\Lazarus_Tests\Memo1_bak\$ with Lazarus, so I don't know how and why it searched there. One last comment: As far as I can see, when checking Delphi support, the converter does not rename the .dpr as .lpr and it keeps the .dfm files. I understand why the converter does this, but I suggest it should be mentioned in the documentation. I had at one point a problem with the dfm files: the project wouldn't compile because they were binary. So I opened the Delphi original project in Delphi 6 and wrote the dfm from binary to text. My guess is that for some reason, the converter did not write the lfm copies, so that the only way to compile was using the dfm, which were binary. I am unable to reproduce the issue (the converter now always writes the lfm files) and sorry, I did not keep a copy of the conversion results, so this remark is only for the record. -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Ok, this is the fundamental cause of your problems. The converter searches for unit files from project's sibling directories, meaning the directories that are below its parent dir. Don't place copies of the same project there. This is a useful feature because many projects include their libraries there and they are found automatically. Test again without those copied dirs and let me know what happens. Sorry to disappoint your hopes, but after copying the Delphi sources to c:\temp\lazarus_test_memo (no, temp does not contain any other pascal sources, and C: only contains the fpc/lazarus binaries in different subdirectories), I get the same results: issue with .res file and after commenting out the $R *.res directive, running the application triggers an exception. ... and this time I managed to upload the source successfully :-P I had at one point a problem with the dfm files: the project wouldn't compile because they were binary. The converter is able to convert from old binary DFM to text LFM. It should not cause problems. As I explained, I suppose that for some reason, the LFM files were not created that time. I can't be sure because the directory where this happened has been emptied and recreated numerous times since, but this is the best explanation I can suggest. So this LFM problem would be a sporadic and probably unrelated issue. I only mentioned it because my supposition could be wrong and maybe telling this could help you find where the main problem comes from. -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] Exception in CreateForm after conversion from Delphi
Hello, I am converting a set of old small applications which I probably wrote in Delphi 1 or 2, first version of the sources I have dates from 1996, last version (the version I am converting to Lazarus) from 1999, probably last updated in Delphi 3 I already did the conversion once with Lazarus 1.2 RC1. This first conversion had to be redone because Lazarus signaled an error converting the .res file. I don't remember what I did exactly, but I finally got a conversion without the .res error. Running the new application raised an exception during creation of the main form (this will be explained below), so I decided to start again from a new conversion using Lazarus 20.1.0.14. Lazarus 20.1.0.14 again signals an error while converting the .res file. First compilation shows a few simple warnings about hiding inherited methods. I also get a hint about an exitProc which I'll explain later. So I remove them with hints and recompile. Lazarus hangs at that point, nothing in the output window, impossible to close the IDE (although it is responsive, I can for example open menus). I end up stopping Lazarus forcefully. After reloading Lazarus, I get the same error about the .res file. I overwrite the .res with the one 1.2 RC1 generated, and now it compiles. When running the application, I get again the same exception. So I decide to try to correct some code which is probably not valid any more: I move the contents of an exitProc to the finalization section and remove exitproc handling. I still get the same exception as with 1.2 RC1: error 1407 in Win32WSControls.FinishCreateWindow. This is triggered by the first CreateForm which is in the dpr. If I comment out the CreateForm, I get the same exception for the next CreateForm. The debugger shows that upon calling CreateWindowEx, pClassName contains Window. I found on the Lazarus forum a discussion about error 1407 in 2009. The solution was to add Application.initialize in the lpr. But the converter did not create a lpr file, so I checked the dpr file and indeed found that Application.initialize was missing. Adding it solved my problem. Why didn't the converter create a lpr file? Did I do something in the settings which caused this? I checked the conversion by 1.2 RC1, I did get a lpr, but it did not contain Application.initialize either. Shouldn't the converter add this line? What are those .res conversion errors? The only reference I found is in the Code_Conversion_Guide, but it seems quite outdated, and I could not find reference to the resources files in the converter documentation. -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Getting an average months is completely useless IMO. Who wants to get such a result for what purpose? Like I said: you can argue whether the functions are useful. They are there for Delphi compatibility. Feel free to provide other functions, I will happily accept them.

No, I am not sure, as I stated in my first answer, I am answering from memory, all my answers here are mainly guesses. Either my first assumption is right or maybe whoever wrote the the button code example thought that VirtualTreeview behaved like IndexOf (which is what I would have expected too). If you are interested, I still have an old version from 2001 on a backup , I could check it. I see 2 options: either restore the old functionality if needed I don't believe that an old functionality exits. It looks as if it was like that from the beginning. Well then, I can add a variant to my first option: create the functionality (since IMO it should be there). If I read the code correctly, if the parameter is the root, AbsoluteIndex will answer 0. If the parameter is not found, AbsoluteIndex will answer 0 too. Yes. There are 3 cases where the result is 0: 1.) Node is nil 2.) Node is the (invisible) root node 3.) Node is the first (visible) node All of them result in zero so these cases cannot be distinguished by the function result. Is this deliberate? That's the question.
