[Lazarus] dbgrid with a lookup field
please see https://docs.google.com/document/d/1RprJLM1i7dgJvfz-lDryH-Jc9I8xVv8gvzsKeYoI6Ps/edit?usp=sharing I have a DBGrid with a lookup colum, say column 0. The user selects a row in the picklist and the focus goes to the undelying lookup cell (0), what makes sense. However I'd like the focus set to cell with index 2 in the row. How do I do that? Which event is fired when the user makes a selection in a lookup column? Thank you Peppe Polpo -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
[Lazarus] question re tdblookupcombobox
the string to display on screen (property DataField) is short. The strings that are listed for selection (field ListField) are wide. I would like to have the control width = 66 pixels and the drop-down list width = 200 pixels. Is there a way to get this behaviour? Right now, the drop-down list is 66 pixels and as a result the strings in the list are truncated...very ugly.

[Lazarus] vertically space controls
I select N controls in a form. C1 is the top control. C6 is the lowest control. I want controls C1..C6 be equally spaced in the vertical space given by C1.Top and C6.Top. In Delphi 5 IDE I had the Alignment Palette by which I could do that (and other useful operations). I cannot find the same tool in Lazarus v. 2.2.4. Is there such a tool?

[Lazarus] html server doubts
I wrote a BE server expanding the TTestHTTPServer I found in the samples. Each inbound call is handled by (common) code that sets a number of global variables like sessionID, url, method etc. Then the call call goes thru the Match function of several specialized components. When the Match function of component X returns TRUE, this component is the one that does the rest of processing:, i.e. read the incoming payload (in case of a POST), read the inline parameters (in case of a GET), query the DB, write a result etc Now I wonder if this working is safe for a server that handles multiple calls. I mean: the inbound calls are produced by visitors of a website. Say a call produced by visitor A comes in at time T1 and immediately after it (at time T2) a call produced by visitor B reaches the server, the global variables will be rewritten possibly before the first processing is completed, what could cause havoc. Shouldn't the memory used for each call be different? Shouldn't I use threads? Or - due to some magics of class TFPHTTPServer - is the memory _already_ different at each new call? I hope I did not say something too stupid... Peppe Polpo -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

[Lazarus] questioning ARequest: TFPHTTPConnectionRequest :)
my simple BE server uses this function to handle all inbound calls: procedure TTestHTTPServer.HandleRequest( var ARequest: TFPHTTPConnectionRequest; var AResponse: TFPHTTPConnectionResponse ); When the call is a POST, I want to read the json payload inside ARequest. I expected to find a property like Body:string inside TFPHTTPConnectionRequest, but I could not find it. How do I get the the json payload which is inside ARequest?

[Lazarus] revamping a very old print
I would like to give a new life to a very old application that was
written in foxplus (a xbase dialect) in 1990 :)
At that time, the display was 80 char per line and the printer was 132
char per line, so data was printed using the logics you will find at
the bottom of this message.
I wonder if I can still use the old code somehow.
My idea is:
1. I get the printer PageWidth in pixel
PageWidth:=Printer.PageWidth;
2. I get the printer PageHeight in pixel
PageHeight:=Printer.PageHeight;
3. I get the height of a line
LineHeight:=Printer.Canvas.TextHeight('M')+5; // I add a few pixels to
prevent text lines to overlap;
4. I get the number of rows in a page
MaxLinesNo:=PageHeight div LineHeight
5. now lets translate line
@7,87 SAY "CITTA'PARTITA IVA"
"7" --> translates into yPos:=LineHeight*7
"87" --> translates into xPos:= round (87/132*PageWidth);
so I write
Printer.Canvas.Textout(XPos, YPos, 'CITTA'PARTITA IVA');
6. how do I set the size of the font? I am expecting not less than 56
lines in a page, so I shrink the font size until I get
LineHeight <=Printer.PageHeight div 60
7. I am surely missing something. Any help?
Thank you

Re: [Lazarus] SQLDBRestBridge
I am puzzled by TMS Software. 1. there is one demo specific for SQLDBRestBridge, but the application is obviously bugged, as you see from the following screenshot https://i.ibb.co/m4wVGtM/2.jpg as a start, the code for the login and logout button is the same, what cannot be 2. the support will deny even under torture the idea that TMS code can have bugs. The fault is always yours. You did not read the manual carefully (666 pages) or did not study CORS carefully or have knowledge gaps. All true in my case... but I can see a bug when I meet one :) 3. in the end, they will suggest you buy their bridge solution, called XData, as they cannot waste their time with a bridge server they did not write (verbatim) :) Probably (I reckon) they are not very interested in the Lazarus market, as they gain most income from the Delphi market. As a matter of fact, I find their support not helpful at all. They dont help you to solve your problem: they will deny that a problem exists or will pretend that you will be able to solve your problem after a few months' study of technical documentation :) I bought TMS Web Core months ago with the idea of quickly write web applications in Lazarus, with a special aim at their TWebGridComponent, but I can say today that it was no wise purchase :) Thank you Peppe On Tue, Nov 8, 2022 at 7:56 AM Michael Van Canneyt via lazarus wrote: > > > > On Mon, 7 Nov 2022, duilio foschi wrote: > > > I fixed the code in Lazarus and got a client based on BufDataClient > > that successfully talks with a restbridge server. > > > > As a next step, I'd like to connect to the same server from a TWebForm > > of TMS Web Core library. > > Normally, TMS Web Core contains a dataset component that handles SQLDBRest > connections?. > > I wrote it myself for them. > > > > > I started with a slow step.

Re: [Lazarus] SQLDBRestBridge
I fixed the code in Lazarus and got a client based on BufDataClient
that successfully talks with a restbridge server.
As a next step, I'd like to connect to the same server from a TWebForm
of TMS Web Core library.
I started with a slow step. There is only a TWebHttpRequest in the
form (which has the same functions of a TFPHTTPClient) and it issues a
GET to URL
http://localhost:3000/metadata/?fmt=json=0
This command works ok in the windows client.
Here, I get the errors shown in pic
https://i.ibb.co/dpsjfQQ/1.jpg
The message (a CORS error) is attached below.
Weird enough, the message is there even after changing the server code
in this way:
original code:
FDisp.DispatchOptions:=FDisp.DispatchOptions+[rdoCustomView,rdoHandleCORS];
new code
FDisp.DispatchOptions:=FDisp.DispatchOptions+[rdoCustomView];
Is there a way to tell the server to ignore CORS errors?
Or there a way to sweet-talk the server to accept the requests from a
TMS Web form? :)
Thank you

Hi Michael, I am digging into your SQLDBRestBridge component. Very useful code. I could fix and run both the server part and the client part (I used the BufDataset client). My code (with very few changes applied to the original one) can be downloaded from this link: https://mega.nz/file/Gxx3FBya#LbvDvuFnH5rUDVAdPoGyuUCnkNE761A62SZ1MYX8oFQ I hope it be helpful for somebody. I have 2 questions: 1. the client needs to know the name of the primary key (PK) of each table. Is there a way to ask the server for the name of the PK of table A? Or to have the PK listed in the metadata? 2. the client needs to periodically refresh the visible rows in the event that another client applied changes to the DB. How is this done? I reckon that the client will remember the last command like BASEURL/resourcename?limit=10=50 and reissue it. Right?

Re: [Lazarus] testing demorestbridge without a web server: is that possible?
I tried to run demorestbridge inside Lazarus in debug mode.
When the web browser points to
http://localhost:3000/REST/metadata
the debugger shows an error message that says:
'project SQLDB REST bridge raised an exception of class 'EHTTP' with
message: No REQUEST_METHOD passed from server.. At address 10009D512'
Any idea what this could mean?
Thank you

You can test this by typing the following in a browser address bar:

and you should get the metadata from the REST service.

I tried this but I dont get the metadata as expected.
Instead, the browser displays the following message in json format

"error" : {
"code" : 404,
"message" : "NOT FOUND"
}
}
>>
(you may need to provide the username and password you configured in the

When we talk about username/password do we mean one of the rows of table USERS?
I run bufclient but the answer is always the same: 404 NOT FOUND
What am I missing?

[Lazarus] testing demorestbridge without a web server: is that possible?
following the suggestions offered by zeljiko (thank you, zeljko), I was able to compile and successfully run demorestbridge.exe Albeit no message is displayed when the EXE starts, I can see that the application is alive and answering requests at port 3000 (I use command >netstat -bano for this). The next step I'd like to reach is to run a client demo that will communicate with the server above. Demo bufclient compiles successfully At start time, I need to insert data into 3 boxes: 1. URL 2. username 3. password #2 and #3 are no problem, of course. #1 puzzles me. The box has the following string preset http://localhost:3000/ To my poor knwoledge, http requires a web server and I have no web server running in my PC with windows 7. Is there any way to do a quick test of demorestbridge.exe without installing a web server? Probably a stupid question...

[Lazarus] demorestbridge
I am trying to use the demo that I find in directory C:\lazarus\fpc\3.2.2\source\packages\fcl-web\examples\restbridge Following the instructions in file readme.txt, 1. I created a firebird database (test.fdb) 2. I run expenses-fb.sql to create the db structure 3. I run expenses-data.sql to insert some data in the tables Now I read: << You must edit the program to provide the correct database credentials: look for the ExposeDatabase() call, and edit the username/password. You must also change the name and location of the database >> so I changed the original line FDisp.ExposeDatabase(TPQConnectionDef.TypeName,'localhost','expensetracker','You','YourSecret',Nil,[foFilter,foInInsert,foInUpdate,foOrderByDesc]); into FDisp.ExposeDatabase(TPQConnectionDef.TypeName,'localhost','c:\\test.fdb','sysadm','masterkey',Nil,[foFilter,foInInsert,foInUpdate,foOrderByDesc]); (where the database path is of course C:\lazarus\fpc\3.2.2\source\packages\fcl-web\examples\restbridge\test.fdb ) However when I compile and run the demo, I get the following error message: "Can not load PostgreSQL client library "libpq.dll". Check your installation" I noticed that a library of name libpq.dll is inside the demo directory. This library was 32 bits, but I compile the demo at 64bits. I downloaded the 64bit library but still no joy (same error). A solution is suggested here https://forum.lazarus.freepascal.org/index.php?topic=43476.0 with several DLLs copied into the working directory but... who wants Postgres? I only work with Firebird. How do I change the code so that only Firebird databases are handled (and no Postgres DLL is needed)? Also: how does the bridge know about the database type one wants to use? I could find no explanation re this question in pages https://wiki.freepascal.org/SQLDBRestBridge Any help?

Re: [Lazarus] trying to read an EXE
I followed Bart's suggestion and added the -al switch to the fpc.cfg file.
This was probably the right move, as - after a new compile - I could see
the wanted .s file beside the regular EXE.
I uploaded the .s file here:
https://mega.nz/file/rlpyHa7b#fx0LYTjapmUdFRkzVGCCzFFogqYuEu7UvYQ5HtilLks
I opened the new .s file with a text editor and had a new surprising
result: the instruction
i:=cmbYear.ItemIndex+2005;
is nowhere to be found.
I tried to find the figure 2005 both as 07D5 and as D507: no hit.
I tried to find the string 'peppe' (that I correctly find in the EXE) in
the S file: no hit.
I tried to find the string 'peppe' in hex format (7065707065) in the S
file: no hit.
I tried to understand where the OnClick event could be written, but - with
little surprise - I could not.
I recompiled with no debug info + using the option 'no optimization'. The
new .s file is stored here
https://mega.nz/file/X1B2mJpL#smqDJOoDOBZOMoDUpeNutXw3C3YgqHurbdC6L7m2vf4
The new .s file gives no new information than the old one.
With all this: the EXE works ok.
This case shows that I have a lot of things to learn.
Any help?

[Lazarus] trying to read an EXE
today I did an experiment that gave me surprising results (due to my
ignorance,
of course).
I have an application written in Lazarus and I need to do one fix only.
This line
result:=EncodeDate(
cmbYear.ItemIndex+2005,
cmbMonth.ItemIndex+1,
1);
needs to be changed into
result:=EncodeDate(
cmbYear.ItemIndex+2006,
cmbMonth.ItemIndex+1,
1);
I thought it would be easy to use an hex editor like PSPad hex, find the
number
2005 as 07D5 then fix it (maybe after the right guess in case of multiple
hits).
To my surprise, I could not find the word 07D5. As I vaguely remember the
big endian/little endian question, I tried to look for D507: no hit.
In order to dig into the question, I created a Lazarus windows application
made of a TCombobox and a TButton. I used v. 2.0.6 on windows 7.
I added the following code:
procedure TForm1.Button1Click(Sender: TObject);
var
a:string;
i:integer;
begin
cmbYear.Items.Add('2020');
cmbYear.Items.Add('2021');
Caption:='peppe';
i:=cmbYear.ItemIndex+2005;
Caption:=inttostr(i);
end;
I compiled/linked that application then opened the EXE using PsPad Hex.
Looking for string 'peppe', I can easily spot the part that contains
the code of interest.
Please see here for a screenshot of PsPad Hex:
https://i.ibb.co/2M054Qx/1.jpg
(I encircled a few familiar names).
I cannot understand how this instruction
i:=cmbYear.ItemIndex+2005;
is coded here.
I am no assembly expert, but I expect that the compiler would translate the
instruction into something like
move 2005 to register X
add register X to register Y (where register Y represents
cmbYear.ItemIndex)
move register Y to register Z(where register Z represents var i)
In any case I would expect that the figure 2005 (07D5) be written somewhere,
but facts prove me wrong.
I am very curious: what really happens in the EXE?
In which form gets this instruction compiled?
i:=cmbYear.ItemIndex+2005;
Could someone explain?
Thank you
Peppe

Re: [Lazarus] I say a little prayer (for the Lazarus editor)
Hi Martin, thank you for the detailled instructions. Re your question >does the Caret go to the start of the insert, or does it automatically move one line down too? in Delphi/column mode, the caret moves one line down at each insert. 1. starting from this status https://i.ibb.co/jL30yFx/1.jpg I click ctrl+O+C for column mode 2. I select the text 'peppe'+blank then ctrl-c to save the text into memory https://i.ibb.co/99DH4gc/2.jpg 3. using the arrow keys, I move the caret 2 lines down... https://i.ibb.co/ZHGqZx3/3.jpg 4. after I press ctrl-v, the caret moves 1 line down. This is exactly what I miss in Lazarus :) https://i.ibb.co/ZT6LJdD/4.jpg I will try to fix the point.

Re: [Lazarus] I say a little prayer (for the Lazarus editor)
Hi Martin, I am too lazy to learn how to use editor scripts. Probably it will be more productive to spend some time to correct the editor code. After all, the Jedi editor - written in Delphi and available in source code - behaves like old Delphi editor in column mode. How can I try to fix the problem?

Re: [Lazarus] I say a little prayer (for the Lazarus editor)
Hi Ryan, not the same result IMHO. 1. I column-select the text shown in https://i.ibb.co/WpL6Rmz/1.jpg Now the clipboard contains the text that extends from point (26,66) to point (26,72) 2. I move the cursor to point (27,66). See https://i.ibb.co/zGqQPPT/2.jpg 3. now I would like to press ctr-v 6 times and get the text inserted in the following 6 rows...but I cant. In fact, after the first insert, the cursor stays on row 27. See https://i.ibb.co/v1FJqzg/3.jpg Instead, it should move to position (28,66) 4. pic https://i.ibb.co/jDBfSpZ/4.jpg shows the result I wanted from the start. I can get it only by several uneeded clicks on the arrows keys... 5. my point is: in Lazarus edit the act of inserting a text which is column-selected has the same result that the act of inserting a text which is row-selected. It would be nice to differentiate the results (as it was in Delhi editor) so to satisfy different needs of the coder.

[Lazarus] I say a little prayer (for the Lazarus editor)
If the coder in charge of the editor reads this, I have a prayer for him: 1. The text showed in https://i.ibb.co/0FQV1L0/3.jpg is column-selected using shift+alt+arrow followed by ctrl-C 2. using the arrows key, I move the cursor to the position shown in https://i.ibb.co/VmbVJtg/4.jpg 3. I press ctrl-V. The text ':string' is correctly copied into the expected position but... look at the cursor https://i.ibb.co/PWLfsn9/5.jpg The cursor is now at the position after the 'g' in the same row where the text was copied. So in the Lazarus editor there is no difference in copying a text row-selected and a text column-selected. In Delphi there is a big difference when you copy a text (at least until v. 7, when I stopped using it). Say you copy a text of lenght L from the clipboard into point (x,y). If the text is row-selected, Delphi sets the cursor at point (x+L,y), like the Lazarus editor does. But if the text is column-selected, Delphi sets the cursor at point (x,y+1), in the row below. This enables you to quickly copy several rows of text, as shown here https://i.ibb.co/98Y9WnD/6.jpg This ability is a big plus for a coder...well... at least I remember I was using it often :) . -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

[Lazarus] UDP server
http://www.ararat.cz/synapse/doku.php/public:howto:udpserver this is the code suggested to write a UDP server with synapse. The code uses an infinite loop in a thread. I find this solution rather ugly. I would expect an event OnReceiveData that apparently is not there. The socket allows for a callback procedure of type procedure OnStatus(Sender: TObject; Reason: THookSocketReason; const Value: string); However it seems that this callback only works when the command RecvPacket or similar is issued and as far as the relative timeout does not elapse. Do I understand well? There is now way to use an event to collect data in synapse? An infinite loop is the only way?

https://www.cybelesoft.com/thinfinity/virtualui/ has somebody tried the product above? Can it be a real alternative to web programming? Thank you Peppe Polpo -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
Re: [Lazarus] devmgmt.msc
Hi Jose', doubting a configuration error, I uninstalled Lazarus, then installed it again (current version is 1.8.2). Unfortunately I could not get rid of the error on TLibHandle. Then I found out that this type (TLibHandle) is not declared in system.pas but in rtl/dynlibs.pas http://i67.tinypic.com/20ft940.jpg I fixed the problem by adding dynlibs.pas to the project. Unfortunately when I compile the code I get new error messages (see below) in unit lnfodwrf. See http://i68.tinypic.com/116qrdy.jpg Well, I am sure I will fix all problems before or later :) Thank you Peppe lnfodwrf.pp(846,23) Error: Incompatible types: got "" expected "" -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
Re: [Lazarus] devmgmt.msc
Hi Jose', thank you for the code, but 1. I get a number of error messages while compiling the unit with Lazarus 1.6.4 under W7 (see below) 2. I cannot understand how I can get the enumerated COM device names into a TStringList as I need to process the names.

[Lazarus] devmgmt.msc
if I run devmgmt.msc on W7 I get this info on screen: http://i66.tinypic.com/2lucq4n.jpg Is there a Winows API I can call from my Lazarus program and get the same info ? My aim is to detect which COM number was assigned to the USB device "MSP Application UART1" Thank you Peppe -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
Re: [Lazarus] Plivo API
Hi Mattias, your code shows what Plivo probably does :) After recording a call, Plivo will call my remote application X (I will write the URI of X in a configuration file) with Https/Post. At the time of the request Plivo passes the URI of a MP3 file to application X. This information is written in a XML file, but lets say a text file just to hide details. I need to write application X. This application X wont make calls, but will be called from 3th party software (Plivo). How do I read the parameters passed when a Https/Post request is done to my code ?

[Lazarus] Plivo API
I am wetting my feet in Plivo API (www.plivo.com). " Plivo communicates with remote applications built by businesses through a series of API calls. These back and forth calls between Plivo and other applications are communicated through XML (Extensible Markup Language). " Say that at a given time Plivo calls application X with HTTPS/Post and passes it a XML file. I need to write a minimal application X in Lazarus that will write the XML file to disk Could you point me to some sample code possibly using Synapse ?
