    Putting a DialogBox into a DLL?

    Can you put a DialogBox into a DLL? I need for my DLL's to be able to control some of their internal parameters during debuging stages and id like to be able to pull up a dialog box and just change their values. I tried just putting one in, and exporting a method that calls DialogBoxParams but it just causes the program to close.

    Code:
    // from Batch.h
    extern "C" DLLAPI void ParamDialog(const HINSTANCE& hInstance, const HWND& hParent);
    //Pre:
    //Post:
    
    INT_PTR	CALLBACK DialogProc(HWND hwndDlg, UINT Msg, WPARAM wParam, LPARAM lParam);
    //Pre:
    //Post:
    
    //from Batch.cpp
    void ParamDialog(const HINSTANCE& hInstance, const HWND& hParent)
    {	int iDlg = ::DialogBoxParam(hInstance,
    		                            MAKEINTRESOURCE(IDD_DIALOG1),
    		                            hParent,
    			            DialogProc,
    			            NULL);
    }

    Ok, i figured out why the program was closing, but now it wont load the Dialog. I mean it loads the DLL fine. Loads the function fine. But when I call the DialogParam function nothing happens, nothing is displayed. I made sure to have the Dialog visible in its properties.
