CVI Application Windows Class Name question

[ZVS]

When my CVI application is running and I run Microsoft Spy++, it shows the Window Class Name is "CVIRTLVDChild00400000".

It looks like this is a typical name and if I run different software made with CVI runtime all windows have this class name.

I use another software that may communicate with other running application using their Windows Class Name.

So the question is: Is there a way to modify the Windows Class Name for main window for a particular CVI project?

No, the window class name is actually hardcoded in the CVI Run-Time Engine. I don't believe there is a way to change the name of an existing class name either. You can programmatically get the class name in CVI:

        intptr_t wnd;
	int status = 0;
	char className[256];
	
	wnd = GetCVIWindowHandle ();
	status = GetClassName((HWND)wnd, className, 256);

Thank you for your reply, D Biel.

I expected that it is not possible since it is too "internal" thing. So I was forced to switch to another solution.

P.S. I hope some day a status bar and "decoration" button will appear in the CVI control list 😉

Hi ZVS,

a status bar has been suggested here and you are welcome to support it

[ZVS]

I would like to support it but did not find how.

For myself I use the Windows Status bar control and it looks and works fine except a callback and control sequence. Screen is attached.

ZVS,

You can just click the up arrow to give the idea kudos. The highest kudo ideas draw the most attention from our R&D department.
