My macro works as expected, as it's replaced with the CreateWindowEx_ line which returns the hWnd.

Macros don't return anything. You need the window handle of the control. If you stuck the HorizontalbarGadget line as a macro in a #WM_SIZE event it would create a new window every time it resized, resulting in hundreds of new windows in no time and a memory leak you could drive a truck through.

ts-soft, very nice piece of work! It's well suited for just this kind of thing as well as having much more potential.

Try it!! Use my macro, create a gadget with it, store the 'returned' hWnd and do whatever you want with the hWnd.

Fred said that macros get processed before the line, which means: this line:

Code: Select all

hWnd=HorizontalBarGadget(0, 5, 5, 100)

equals to this:

Code: Select all

hWnd=CreateWindowEx_(0,...........)

and as far I can tell, createWindowEx returns a hWnd. When you store that hWnd, you can use your #wm_size event without problems at all.

EDIT: REad my post carefully!
Here it's again if you didn't see it correctly:

I said my MACRO gets automatically REPLACED with the CreateWindowEx_ one. The CREATEWINDOWEX_ function RETURNS the HWND

I didn't say anything about my macro would return something.

Yes, I get it - did you read what I said about a memory leak? If you do it that way a new window gets created every time a resize happens - the old one doesn't get freed. If you don't believe me just stick it in your main loop and run with the debugger -> CPU Monitor running. Watch the memory usage for the program rise and rise.

ok I'll check it. but if there's no problems with the memory at all, you shall buy me my coffee

Ease off a bit, please, josku. You're OTT at times.

OK. I am going to take things more easily. I know I made mess in this forum. And I know I go very easily off-topic. I am really sorry. Just had a few bad days.
