CreateDialog() fails (Win32 dialog creation function)

Anonymous — Mon, 07 Aug 2023 08:34:40 GMT

Instead of creating a User Control, for various reasons, I want to launch a modeless dialog box using CreateDialog(). I've created a dialog (IDD_FORMVIEW) in the resource file (note that there is an *.rc2 file, but when you create a dialog, an *.rc file is created along with resource.h), added the resource.h file to my cpp file, and modified the entry point in my cpp file as follows:

static void Do_APIMyAddOn (void)
{
/*
// ArchiCAD API modeless dialog code starts here...
GSResModule actResModule = ACAPI_UseOwnResModule ();

myAddOnDialID = DGModelessInit (MYADDON_ID, APIMyAddOn_Handler, NULL, 1);
ACAPI_ResetResModule (actResModule);
// ArchiCAD API modeless dialog code ends here...
*/

//
// Win32 modeless dialog creation code starts here...
DWORD error;

if (hwnd == NULL) {
hwnd = CreateDialog(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_FORMVIEW), NULL, (DLGPROC)DlgProc);
if (hwnd == NULL) {
error = GetLastError();
} else {
ShowWindow(hwnd, SW_SHOW);
}
}
// Win32 modeless dialog creation code ends here...
//
}

hwnd == NULL and error == 1814 ("The specified resource name cannot be found in the image file"). Any ideas on why I can't create the dialog via the resource mechanism?

thanks in advance, Chuck

I think even if you used the Windows native dialogs, you'd still have to set the resource module to the add-on using ACAPI_UseOwnResModule. But first check if the resource is really there by opening the compiled add-on in resource view.

HTH,

Here's are the parameters that make it work:

hwnd = CreateDialog(ACAPI_GetExtensionInstance (), MAKEINTRESOURCE(IDD_DIALOG1), ACAPI_GetMainWindow (), (DLGPROC)DlgProc);

(Substitute your own IDD and procedure for my IDD_DIALOG1 and DlgProc respectively).

thanks, Chuck

Hello,

I've took working example plugin from ArchiCAD SDK, and add code which should open dialog box (as shown below). But each time I use any of <windows.h> functions ArchiCAD crashes with out any understable and visible error for me. Bug reporting tool opens, and that's all of my dialog box. Application exits after it shows a border of my dialog box. Buttons inside dialog are invisible. What could be wrong? I use ArchiCAD 10 and sdk 10. Changed plugin name: Automate_Functions (added one position to menu):

HWND _win;  
  
BOOL CALLBACK DialogProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)  
{  
	return FALSE;  
}  
  
static void Do_Window()  
{  
	_win = CreateDialog(ACAPI_GetExtensionInstance (), MAKEINTRESOURCE(IDD_DIALOG1), ACAPI_GetMainWindow(), (DLGPROC)DialogProc);   
	//ACAPI_GetExtensionInstance();  
	//ACAPI_GetMainWindow();  
	if(_win != NULL)  
		ShowWindow(_win, SW_SHOW);  
}

best regards
