CreateDialog

This function creates a modeless dialog box from a dialog box template resource.

HWND CreateDialog( 
HINSTANCE hInstance, 
LPCTSTR lpTemplate, 
HWND hWndParent, 
DLGPROC lpDialogFunc); 

Parameters

  • hInstance
    [in] Handle to the module whose executable file contains the dialog box template.
  • lpTemplate
    [in] Long pointer to the dialog box template. This parameter is either the pointer to a null-terminated character string that specifies the name of the dialog box template or an integer value that specifies the resource identifier of the dialog box template. If the parameter specifies a resource identifier, its high-order word must be zero and its low-order word must contain the identifier. You can use the MAKEINTRESOURCE macro to create this value.
  • hWndParent
    [in] Handle to the window that owns the dialog box.
  • lpDialogFunc
    [in] Long pointer to the dialog box procedure. For more information about the dialog box procedure, see DialogProc.

Return Values

The handle to the dialog box indicates success. NULL indicates failure. To get extended error information, call GetLastError.

Remarks

The CreateDialog function uses the CreateWindowEx function to create the dialog box. CreateDialog then sends a WM_INITDIALOG message to the dialog box procedure. The function displays the dialog box if the template specifies the WS_VISIBLE style. Finally, CreateDialog returns the window handle to the dialog box.

After CreateDialog returns, the application displays the dialog box (if it is not already displayed) by using the ShowWindow function. The application destroys the dialog box by using the DestroyWindow function.

Windows CE does not support all styles in the DLGTEMPLATE structure. This structure is in the template identified by the lpTemplate parameter*.*
