Dialogs and graphics

[Loafy]

Hello,

I am automating an application "Unigraphics NX 3.0" using c/c++ through VS.NET i am trying to bring up a progress bar dialog, i can get the dialog to come up but after the dialog comes up and i try to change the display to the next part in the list i get a memory access violation

if i remark the line AFX_MANAGE_STATE(AfxGetStaticModuleState());
then it switches display parts fine, but the dialog wont popup...
here's a code snippit,
can anyone tell me what im doing wrong?

	tag_t
		part,
		starting_part;
	HINSTANCE
		hInstance;
	HWND 
		pbar,
		ugwin,
		hWnd;
	int
		pct,
		number_open_parts,
		u_func_usage;
	char
		part_fspec[MAX_FSPEC_SIZE+1],
		temp_file[MAX_FSPEC_SIZE+1],
		log_file[MAX_FSPEC_SIZE+1],
		u_func_name[MAX_LINE_SIZE+1];
	UF_UNDO_mark_id_t
		mark_id;
	FILE
		*mess_file;

	AFX_MANAGE_STATE(AfxGetStaticModuleState());
	hInstance = AfxGetInstanceHandle();
	ugwin = GetActiveWindow();
	hWnd = CreateDialog(hInstance, MAKEINTRESOURCE(COS_DIALOG_MAIN), ugwin, &WndProc);
	pbar = GetDlgItem(hWnd, COS_PROGRESS);
	starting_part = UF_PART_ask_display_part(); 
	mess_file = fopen(temp_file, "w");
	number_open_parts = UF_PART_ask_num_parts();
	UF_CALL(UF_DISP_set_display(UF_DISP_SUPPRESS_DISPLAY));
	SendMessage(pbar, PBM_SETPOS, 0, 0);

	for (int i = 0; i < number_open_parts; i++)
	{
		pct = ((i + 1) * 100) / number_open_parts;
        SendMessage(pbar, PBM_SETPOS, pct, 0);
		part = UF_PART_ask_nth_part(i);
		UF_CALL(UF_PART_ask_part_name(part, part_fspec));
		UF_CALL(UF_PART_set_display_part(part));
	}
	UF_CALL(UF_PART_set_display_part(starting_part));
	UF_CALL(UF_DISP_set_display(UF_DISP_UNSUPPRESS_DISPLAY));
	UF_CALL(UF_DISP_regenerate_display());
	DestroyWindow(hWnd);
	fclose(mess_file);
