Mein Problem ist, dass meine DialogBox nicht angezeigt wird. Ich habe bereits die Hinweise aus dem FAQ durch, doch meine DialogBox wird trotzdem nicht angezeigt.

#include <windows.h>
#include "resource.h"

LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM);
BOOL CALLBACK DialogProc (HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
{
		static char szAppName[] = "Find";
		HWND hwnd;
		MSG msg;
		WNDCLASSEX wndclass;

		wndclass.cbSize = sizeof (wndclass);
		wndclass.style = CS_HREDRAW | CS_VREDRAW;
		wndclass.lpfnWndProc = WndProc;
		wndclass.cbClsExtra = 0;
		wndclass.cbWndExtra = DLGWINDOWEXTRA;
		wndclass.hInstance = hInstance;
		wndclass.hIcon = LoadIcon (hInstance, szAppName);
		wndclass.hCursor = LoadCursor (NULL, IDC_ARROW);
		wndclass.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1);
		wndclass.lpszMenuName = NULL;
		wndclass.lpszClassName = szAppName;
		wndclass.hIconSm = LoadIcon (hInstance, szAppName);

		RegisterClassEx (&wndclass);

		hwnd = CreateDialog (hInstance, szAppName, 0, DialogProc);

		ShowWindow (hwnd, iCmdShow);

		while (GetMessage (&msg, NULL, 0, 0))
		{
				TranslateMessage (&msg);
				DispatchMessage (&msg);
		}

		return msg.wParam;
}

LRESULT CALLBACK WndProc (HWND hwnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
		switch (iMsg)
		{
				case WM_COMMAND :
						switch (LOWORD (wParam))
						{
								case BNOK :
										break;
								case ED_WILDCARD :
										break;
						}

						break;

				case WM_DESTROY :
						PostQuitMessage (0);
						return 0;
		}

		return DefWindowProc (hwnd, iMsg, wParam, lParam);
}

BOOL CALLBACK DialogProc (HWND hDlg, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
		switch (iMsg)
		{
				case WM_INITDIALOG :
						return TRUE;
				case WM_CLOSE :
						EndDialog (hDlg, 0);
						return TRUE;
		}

		return FALSE;
}

Und hier mein Resourcenskript:

Find DIALOG DISCARDABLE  0, 0, 272, 330
STYLE WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU
CAPTION "Find"
CLASS "Find"
FONT 8, "MS Sans Serif"
BEGIN
    DEFPUSHBUTTON   "Verzeichnis auswählen",BNOK,5,5,90,14
    EDITTEXT        ED_WILDCARD,5,30,90,15,ES_AUTOHSCROLL
    EDITTEXT        ED_AUSGABE,6,61,254,259,ES_MULTILINE | ES_AUTOVSCROLL | 
                    ES_AUTOHSCROLL | ES_READONLY
END

Vielen Dank für eure Hilfe.

ShowWindow (hwnd, iCmdShow);

durch die hier:

ShowWindow (hwnd, SW_SHOW);

CreateDialog(instanceHandle, MAKEINTRESOURCE(IDD_DIALOG1), 0, DialogProc);
