Hi guys,

here is a super cool demo. Nothing fancy on the surface but it is really nice how everything works together to get a lot done with 1 line of code!!!

https://github.com/Atozed/IntraWeb/tree/...legramDemo

You just need to build it, copy 2 OpenSSL DLLs to the same folder where the EXE is and have fun!

You can send messages from the demo application directly to our @IWTelegramComponent Telegram channel.

Imagine the possibilities:

For instance, you can create an exclusive Telegram channel for your application and let your customers send support questions/tickets. Or... you can automate reporting of exceptions and have an exception handler sending exceptions to your channel... usage statistics.. whatever!
The possibilities are unlimited! 

Please let me know what you think!

BTW: Open SSL libs can be downloaded here:

I suggest:

Cheers!

Hi, just wondering: does TIdSync nowadays still work in the latest Indy version?  I see a warning saying it is deprecated and suggest to change to use TTThread.Synchronize, however in and old "indy indepth" doc, it introduces TIdSync as following

TIdSync
TThread has a Synchronize method, but it does not support the ability to pass parameters to
synchronized methods. TIdSync allows for synchronizations with the ability to pass parameters to the
synchronized methods as well. TIdSync also allows for return values to be returned from the main
thread.


I use TIdsync a lot with passed in paramteres and return value (mainly to read property value of a UI component on the main form).
Now, if I switch to use TTThread.Synchronize, is it really as easy as using TIdsync to allow pass parmater to and get return value? 
And if I keep the code as is (using TIdsync), what would be a potential risk of this in future considering it is now "deprecated"? 

Thank you very much.

Hello, I'm using IW 15.2.10 And Delphi 10.3 trying to change the color of the font of text in cells within an IWGrid when OnRenderCell is triggered:

Hello,

I am using Delphi 10.4.1 with IW 15.2.24.
I am trying to show a MS SQL Server money (Currency) column in a TIWJQDBGrid but the grid reamins in "Loading" status.
Cause my Windows PC is set up to use Italian language I suppose the number format (with comma as a decimal separator and  dot as thousand separator) does not match the format expected from the grid.
How can I solve this incompatibility or is there an event to change the number format ?
I try to change the format at object field level but it did not work...

Thank you,
Davide

I have UIWServerControllerBaseConfig define two forms:

IWExceptionRenderer.SetExceptionRendererClass(TIWExceptionRendererEx);
 if FLock<>nil then FreeAndNil(FLock);
 FLock:= TCriticalSection.Create;
THandlers.Add('', 'Form1', TContentForm.Create(TForm1)); http://localhost/form1 (first load)
THandlers.Add('', 'Form2', TContentForm.Create(TForm2)); http://localhost/form2



In UserSesssion i have define procedures LoadDatas/ClearDatas with my TDatas. Both Forms used this procedures.

If switch Form2 then i want ClearDatas in Form1? If i dont, i get memory leaks from Form1, if destroy Usersession! Who Release!

Hi guys,

here is a new update for IW 15 branch:

https://www.atozed.com/2021/02/intraweb-15-2-24/

Highlights: 

• New IWTelegram class (a simple and effective way - fire & forget - to send messages from your IW server to any Telegram channel, via Telegram API). Demo soon.
  
• Fixed/enhanced IWjQAccordion and IWjQPageControl now with render async capabilities as well. Another demo coming!
  

I am exploring the recently added TIWjQDBGrid component, and find it quite useful.

But I can not figure out how to obtain the selected row selection status when the row is re-clicked to unselect without rewriting/adding some custom javascript.

The thing needed was to add 'status' to the javascript code and call an additional function passing the 'status' value through a separate callback.

$("#grid_MYGRID").jqGrid({...onSelectRow:function(rowid,status,e){exMyGridSelectRow(rowid, status); return MYGRID_onSelectRow(rowid,e);}

Is it possible to let IW 15 also render js to return the 'status' parameter in the callback EventParams in future versions or is there any other way to aquire the row selection status in the current version?

Hello.

I would sometimes like to dynamically set the size of the TIWListbox.

I was able to calculate the height of the ListBox1:
MyHeight  :=  round(ListBox1.Items.Count * (ListBox1.Font.Size * ListBox1.Font.PixelsPerInch/72)) +  ListBox1.Items.Count * 3;

I don't know how to calculate the width. In Delphi, canvas is used for this. But TIWListbox has no canvas.
How to calculate the width of any any row of a ListBox1?

Hello,

according to the demo on GitHub, I tried the following:

with MW do begin

  Reset;

  Autosize := false;
  CloseButtonVisible := true;
  Draggable := false;
  WindowWidth := 80;
  WindowHeight := 80;
  Src := 'legacy.pdf';
  OnAsyncClick := nil;
  OnAsyncClose := nil;

  Show;

end;

MW appears correctly but the PDF is not displayed. The window is empty.

The file is in wwwroot.

Another problem with loading an HTML file (MW.Src := 'legacy.html'):

The file is loaded and displayed. But all special characters (e. g. ä, ö, ü, ...) are displayed as question marks.

Something wrong on my side? 


Thanks for solutions!!

Hello.
I am using Intraweb 15.2.20.
If I stop the timer and then start it again, then the timer does not start counting from the beginning, but ends the time that was not finished before the last stop.
IWTimer1.Enabled := false;
IWTimer1.Enabled := true;
// after assigning a value Enabled := true event OnAsyncTimer will occur in the interval 0.. IWTimer1.Interval

I tried like this:
IWTimer1.Enabled := false;
IWTimer1.Interval := 5000;
IWTimer1.Enabled := true;
However, that does not work either. The first actuation of the timer after these commands can be less than 5 seconds.

Is there a command to start the timer from the beginning?
