Modal Dialog Box

[Pascode]

Hi,
I've been trying for the past couple of hours to get this modal dialog box working, it is basically supposed to ask for text input and once entered will open a message box with that text. At this point though I'd be happy to just get the box up and go from there. I can compile this in visual c++ but it only brings up my main window and nothing else.
I can't see why this isnt working and as Im just learning this now I doubt I will see it myself. Sorry for the length. Im sure it is something stupid that I am doing or not doing, but it would be much appreciated if any is able to read it over and give me any tips!

Thanks in advance..

you need to make a call to the DialogBox() function with appropriate parameters
e.g.

DialogBox(GetModuleHandle(NULL),MAKEINTRESOURCE(IDD_ABOUT),hwnd,AboutDlgProc);

IDD_ABOUT is the dialogbox template you want to show..you should include it in a resource file

#define IDD_ABOUT 1000

IDD_ABOUT DIALOG DISCARDABLE 0,0,250,80
STYLE DS_MODALFRAME|WS_POPUP|WS_CAPTION|WS_SYSMENU
CAPTION "About"
FONT 8,"MS Sans Serif"
BEGIN
	DEFPUSHBUTTON		"&OK",ID_OK,175,18,50,14
	PUSHBUTTON		"&Cancel",ID_CANCEL,174,35,50,14
	GROUPBOX		"About this program..",IDC_STATIC,7,7,225,50
	CTEXT			"An example program showing how to use dialog boxes",IDC_STATIC,16,18,144,33
END
