Modeless Dialog Class Registration Via Win32

See more:

dialog

Hello all,

so I created a modeless dialog to display some results that update periodically (via resource script). I know that I can get the handle of the dialog by FindWindow("#32772","Results"). But, I want to make the class name to my modeless dialog box unique. I tried adding CLASS "MyClassName" to my resource file and then re-register the class by filling the WNDCLASS structure (with the needed wc.cbWndExtra = 30) and calling RegisterClass and them call CreateDialog with the new class name. However, this always returns the NULL handle. Otherwise, I can keep the default class name and call:

hwndDlg = (HWND)CreateDialog(hInst, MAKEINTRESOURCE(IDRESULTS),
hwnd, DlgResultsProc),

which works fine (absent the CLASS "MyClassName").
Could someone present a solution doing this in C?

Thanks,

John
