Hi all,

I'm using IW 15.2.12 and Delphi 10.3.3, but I doubt if this has anything to do with my challenge.

As you all may know, when you open an URL to a high resolution image, this image opens in the browser and the image is scaled to the browser so that it's completely showing.
I would like to achieve the same result, but then in a ModalWindow. But when opening the same highres image URL in a ModalWindow, the image is shown in real size.

Is there a way to show this highres image scaled in a ModalWindow?

Thanks in advance for your tips/solutions!

Cheers, Paul

Hi Alexandre,

when I exit the IW debug dialog after starting an application in the browser and closing it again, I now get an AV with IW 15.2.12.
In the application itself I get AVs in many places, I am now back to IW 15.2.11.

Hi everyone,


Where do you suggest I can learn more about the JQGRID components ?

I know how to create a simple web server using TIdHTTPServer and serve .htm files. But what if I wanted to be able to handle .php files like IIS or Apache would? I assume I would need to download the thread-safe Windows binaries for PHP. Then what? A user requests a link with a .php extension. How do I send the .php file contents (with URL parameters) to the PHP processor, wait for it to spit back any output, and send that output back to the user?

I was using bootstrap components to make responsive size adjustable web application but the problem I am getting is all the component calls client side java script as far as I understood. 
it can call Java script Function written in the same page or it redirects to another page.
But can I call a custom function written in C++ in my web application as I can call it within the web application.

Is there any way to achieve the same behaviour as nowrap for TIWCheckboxes? i.e. i have text associated with a checkbox and want to ensure that the text does not wrap at run time.

It is possible to add a custom header to each request?

Using IW 15.2.12 with Delphi 10.3.3 (planning to move to 10.4 soon for this project).

The reason I'm asking is that a customer of mine has mutiple servers, and a load balancer who will send customers to one of these servers based on some criteria in the request header. We were thinking of a way to add the IW session ID to the request header. Or some other means of identification. But I have no idea how to programmaticlaly add something to the request header. And nut just for regular "Click" events, but also for the AsSync events of course.

I hope soemthing is possible, thanks in advance.

Howdy All!

I have a certain customer that after 8 to 10 hours of heavy use, my web application crashes with an EAccessError. 

The stack trace doesn't show anything useful.

If I had to guess, I would guess a possible memory leak but unfortunately FASTMM is practically useless for C++ Builder 10.2.3 and I gave up years ago trying to get it to work (just google my name with FASTMM).

Any how, I was wondering if anyone has written a module or application that monitors a web application for memory usage and somehow restarts it with a command line batch file if necessary?

Or does anyone have any other solution?

Big K - will IW17 have any built-in ability to take a make an IW web application be able to run in multi-process / multi-thread mode as a way of load balancing / restarting processes?

Thanks,

Shane
