Hi,
I have project in win32 and it creates one dialog include some Control tools.

When I using this function:

C++

nRet = DialogBoxParam(hInst1, MAKEINTRESOURCE (IDD_DIALOG2), hWnd, LoginDlgProc1, 0);

It creates Dialog box and when using this function not creates:

C++

HWND g_hDlg = CreateDialogParam(hInst1, MAKEINTRESOURCE(IDD_DIALOG2), hWnd, LoginDlgProc1, 1);

Any problem with second function?
Regards,

See this MSDN page[^], with particular reference to the difference between Modal and Modeless dialogs.

As Richard and Rezame stated, the answer lies in modeless vs. modal window behavior. One of those calls creates a modal window that is by default shown, the other call creates a modeless window that is not necessarily shown by default (window exists but may be invisible).

Must use ShowWindow() function for that.
