This function creates a modal dialog box from a dialog box template resource. DialogBoxdoes not return control until the specified callback function terminates the modal dialog box by calling the EndDialogfunction.
int DialogBox( HINSTANCE hInstance , LPCTSTR lpTemplate , HWND hWndParent , DLGPROC lpDialogFunc );
Parameters
Return Values
The value of the nResultparameter in the call to the EndDialogfunction indicates success. –1 indicates failure. To get extended error information, call GetLastError.
Remarks
The DialogBoxmacro uses the CreateWindowExfunction to create the dialog box. DialogBoxthen sends a WM_INITDIALOG message to the dialog box procedure. The function displays the dialog box (regardless of whether the template specifies the WS_VISIBLE style), disables the owner window, and starts its own message loop to retrieve and dispatch messages for the dialog box.
When the dialog box procedure calls the EndDialogfunction, DialogBoxdestroys the dialog box, ends the message loop, enables the owner window (if previously enabled), and returns the value of the nResultparameter specified by the dialog box procedure when it called EndDialog.
Windows CE does not support all styles in the DLGTEMPLATEstructure. This structure is in the template identified by the lpTemplateparameter .
