[Dev-C++] ID to handle

[Vlada D. <dj...@im...>]

Hi.
Here's the deal: I want to turn window ID number (#define ID_WND 100) to
handle to that window, so I can use it in SendMessage function. I tried to
use MAKEINTRESOURCE macro (HWND hwnd=(HWND)MAKEINTRESOURCE(ID_WND), but it
doesn't work as I expected. I read that return value of it is type LPTSTR.
Can that be cast as HWND? If not, is there some other way to do this?

Regards,
Vlada

To create window from ID use CreateWindow (or CreateWindowEx)

http://msdn.microsoft.com/library/en-us/winui/winui/windowsuserinterface/windowing/windows/windowreference/windowfunctions/createwindow.asp

return value from CreateWindow is HWND (Handle to WiNDow)...

To get handle to one item use GetDlgItem...

And last thing - if you are processing message from that window you
get HWND as first param in its CALLBACK function...

There is a way to get handle by using FindWindow, but I think that you
can use one of previous... if you still don't know to do this give
more info...

This will do. Thanks, Zodiaq.
