[zhgart]

Set up a modeless dialog, but no display when run program, here is codes,


int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow) {
// TODO: Place code here.
MSG msg;
HACCEL hAccelTable;
HWND hDlgModeless;
// Initialize global strings
LoadString(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);
LoadString(hInstance, IDC_WAPP1128_1, szWindowClass, MAX_LOADSTRING);
MyRegisterClass(hInstance);

// Perform application initialization:
if (!InitInstance (hInstance, nCmdShow))
{
return FALSE;
}
hAccelTable = LoadAccelerators(hInstance, (LPCTSTR)IDC_WAPP1128_1);
hDlgModeless = CreateDialog(hInstance,"ColorScrDlg", hWnd, ColorScrDlg);
// Main message loop:
while (GetMessage(&msg, NULL, 0, 0))
{
if (hDlgModeless==0 || IsDialogMessage(hDlgModeless,&msg)) {
if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
}
return msg.wParam;
}
