Hi!
I followed this Delphi sample for accessing columns of a TIWDBGrid using C++Builder, but it does not work. 
Below is my code:

Hi guys,

there is a new update available: https://www.atozed.com/2022/12/intraweb-15-2-69/

I strongly recommend this one because it contains some critical bug fixes (also some interesting new features)

Enjoy! 

I need to upload a PDF file to a WhatsApp Cloud API.
Can someone help me translate this WhatsApp curl example code to Delphi pascal?
Here is the code from the WhatsApp documentation (JPEG example):

Can someone share a sample code that works with TIdTCPServer with SSL TLS?

Why is it so complicated or difficult? Probably I don't understand. There is a lot of different information on the internet. But I haven't seen any information that is completely correct. It could be an example reference code.

Below is the code I wrote (which I don't understand). Please someone explain to me what is missing, wrong or excessive.

1-How do I create Self-Signed SSL with OpenSSL?
2-How do I install these certificates on the server side?
3-Can I connect with the same (with Server) SSL settings for the client?

Also, after I test these codes in windows environment, I will run them under Linux.

I've got some chart.js data in a script inside my HTML file. I can replace part of the chart.js script with tags that I then process in the IWTemplateProcessorHTML's UnknownTag event. This works when I populate the script before the HTML page is loaded. Once the page is loaded, I'm struggling to find a way to force the chart to redraw, so I can inject new data into the chart using the UnknownTag event.

I've tried using WebApplication->CallBackResponse->AddJavaScriptToExecuteAsCDATA(js) to inject some JavaScript, but I don't know enough JS to work out how to get the chart to update.

I've also tried surrounding the chart with divs and giving the div the name of an IWRegion. I then call invalidate on the region, but this didn't work for me.

Any help would be very gratefully received. Thanks.

Hello,

My web server is installed on a Robot which for security reasons cannot be connected to the web.
I used the “MultiSessionssNoCookie” example to display a data grid:
With web access

  /// <summary>
  /// Add the files for the grid
  /// </summary>
PageContext.AddLinkFile('https://cdn.datatables.net/1.10.19/css/jquery.dataTables.min.css');
PageContext.AddScriptFile('https://cdn.datatables.net/1.10.19/js/jquery.dataTables.min.js');
PageContext.AddToInitProc('$("#tbl1").DataTable();');

It works perfectly.

Locally, with files in:
/bin/wwwroot/css
/bin/wwwroot/js
  PageContext.AddLinkFile('/css/jquery.dataTable.min.css');
  PageContext.AddScriptFile('/js/jquery.dataTables.min.js');
  PageContext.AddToInitProc('$("#tbl1").DataTable();');
I have the following error
"class EIWinvalideRessourceException IW_JS_jquery.dataTables.min not found"

Thanks for your help

Hi Everyone,

I'm using Intraweb for 2 Years now, I found this software very useful for my projet.
I have a little problem when I'm trying to open my website from a link outside from Webbrowser (mailbox for exemple), That create always 2 sessions !
I try other examples from Github (ContentHandlersDemo or MultiPageApp) I have the same behavior ! 
How could we make to get only 1 session ?
Thanks for your help

with Intraweb I have a timer which checks every minute to see if the data the user is viewing has changed and a page refresh is required. What code should I use to trigger the refresh. I understand that a component on the form can have its click event executed, but how is that done. I have seen some ideas about WebApplication.CallBackResponse.AddJavaScriptToExecuteAsCDATA but not sure how to use it. Help will be appreciated.

Hi All,

I don't know if anyone has encountered the same challenges as I have, but here it goes.
After upgrading my webserver to Windows Server 2022, my Intraweb applications using TIWAppCache stopped working.

More details:
I create a new Tempfile with: LFileName := TIWAppCache.NewTempFileName('.pdf')
The App does it's thing and saves it's data to this new Tempfile
Finally I process the Tempfile with: HRef := TIWAppCache.AddFileToCache(WebApplication, LFileName, FContentType, ctSession)

But in one of the 2 final steps I get the error: Can't add file <TempFile> to cache. The file does not exist.

All this is done in HTTP.SYS.
When running the same app in SA, all works fine.

I've read about security issues and patches on Windows Server 2022 regarding HTTP.SYS, could it be that this mechanism is unsecure?

I'm using Delphi 11.1 with IW 15.2.68 Ultimate.

Thanks in advance for (possible) solutions!

Cheers, Paul

PS. After moving everything to a Windows 2019 Server, all worked well!
