Hello, Kevin!

This exception occurs when document is generated and opened for preview?

Could you show a screeshot of this preview form without extended borders?

So we're not necessarily opening the file for preview. We are using the Windows ShellExecute function to open the new files. So the files aren't shown within any Alpha Controls form but are opened in whatever default program the specific file type opens in.

Hello!

Could you give me some additional information, please?

I need it for repeating of the issue. How can I repeat it?

This AV occurs when ShellExecute is called?

So the access violation actually occurs after the new file is closed. So maybe it is even with the underlying Windows function for closing windows? It seems to only happen when our application is maximized as well when opening the new file. And to be more specific the actual method call we are using is

Code:

int hResult = (int)ShellExecuteW(Application->Handle, NULL, objectPath.c_str(), NULL, NULL, SW_SHOWNORMAL);

It appears to happen more frequently when on a Windows 10 machine. It will happen on a Windows 7 machine but not nearly as often. It may sound silly too but if the access violation doesn't occur when first opening the new file I was able to get it to appear by spamming the maximize then restore down button of the window many times then closing the window when it's maximized.

Hopefully this helps, if there is anything else you need to know hopefully I can give you an answer.

Thanks!

Kevin

Do you mean – after the window with a file preview closing? And when the main window is activated?

Yes, that is what I mean.
