Hi ~

I've being trying to implement an essential dialog into my program and it won't work. MENUSTYLE is the name of my dialog. Here is my main.cpp file:

/*{ 2007 Elixir Software. Menu code Milonic.com*/

#include <windows.h>
#include "defines.h"

const char g_szClassName[] = "myWindowClass";
static HINSTANCE g_hInst = NULL;

/*Initialise Variables*/
HWND hEdit = NULL;
HFONT hfDefault = NULL;

int ret = NULL; //Variable to store value returned by MENUSTYLE dialog

//MENUSTYLE Procedure
BOOL CALLBACK MStyleProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
switch(Message)
{
case WM_INITDIALOG:

return TRUE;
case WM_COMMAND:
switch(LOWORD(wParam))
{}
break;
}
return FALSE;
}

//The Window Procedure
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_CREATE:
{
/*Create Edit Box*/
hEdit = CreateWindowEx(WS_EX_CLIENTEDGE, "EDIT", "",
WS_CHILD | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL | ES_MULTILINE | ES_AUTOVSCROLL | ES_AUTOHSCROLL,
-2, -2, 442, 352, hwnd, (HMENU)EDIT_CODE, GetModuleHandle(NULL), NULL);
if(hEdit == NULL)
MessageBox(hwnd, "Could not create code view edit box.", "Error", MB_OK | MB_ICONERROR);

SendMessage(hEdit,WM_SETFONT,(WPARAM)GetStockObject(DEFAULT_GUI_FONT),MAKELPARAM(1,0));

/*Set focus*/
SetFocus(hEdit);
break;
}
case WM_COMMAND:
{
switch (LOWORD(wParam))

case DM_FILE_NEW:
{
switch (ret = DialogBox(g_hInst, "MENUSTYLE", hwnd, MStyleProc))
;
//MENUSTYLE declared in style.rc
case -1:
{
MessageBox(GetActiveWindow(),
"Error: Failed to display MENUSTYLE dialog box.\n\nPossible Solution:\n\nRe-attempt to display the dialog. If that doesn\'t\nwork, re-boot your computer.",
"Error", MB_OK | MB_ICONSTOP);
break;
}
break;
}
break;
}
// Break WM_COMMAND

case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc;
HWND hwnd;
MSG Msg;

//Step 1: Registering the Window Class
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName = MAKEINTRESOURCE(MYMENU);//Defined in menu.rc
wc.lpszClassName = g_szClassName;
wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);

if(!RegisterClassEx(&wc))
{
MessageBox(NULL, "Error: Window Registration Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}

// Step 2: Creating the Window
hwnd = CreateWindowEx(
WS_EX_CLIENTEDGE,
g_szClassName,
"Elixir DHTML Javascript Menu",
WS_OVERLAPPEDWINDOW,
300, 200, 450, 405,
NULL, NULL, hInstance, NULL);

if(hwnd == NULL)
{
MessageBox(NULL, "Error: Window Creation Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}

ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);

// Step 3: The Message Loop
while(GetMessage(&Msg, NULL, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}

If it helps, here is my dialog source (so far):

#include <windows.h>

//About Dialog

MENUSTYLE DIALOG 20, 25, 180, 130
/*Left side, distance from left of parent
Top, distance from top of parent
Right, distance from left of dialog / child (width)
Bottom, distance from top of dialog (height)*/

STYLE DS_MODALFRAME | DS_3DLOOK | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU
CAPTION "Customise Menu"
FONT 8, "MS Sans Serif"

BEGIN
CONTROL "About This Program", -1, "button", BS_GROUPBOX | WS_CHILD | WS_VISIBLE | WS_GROUP, 10, 5, 160, 110
END

Please help!
