Converting from MSVC++ 6 to .NET 2003

So, I'm having this REALLY weird problem with a switch statement. I'm manually converting code from a MSVC++ 6 application to a .NET 2003 application.

The following code compiles:

Code:

---

LRESULT CALLBACK DialogProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
        switch(message)
        {
        case WM_INITDIALOG:
                {
                        break;
                }
        case WM_COMMAND:
                {
                        break;
                }
        case WM_DESTROY:
                {
                        PostQuitMessage(0);
                        break;
                }
        case WM_CLOSE:
                {
                        DestroyWindow(hWnd);
                        break;
                }
        default:
                {
                        return FALSE;
                }
        }
        return TRUE;
}

But when I add another case to the switch, like WM_WTF:

(WM_WTF is defined as #define WM_WTF (WM_USER + 20))

Code:

---

LRESULT CALLBACK DialogProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
        switch(message)
        {
        case WM_WTF:
                {
                        break;
                }
        case WM_INITDIALOG:
                {
                        break;
                }
        case WM_COMMAND:
                {
                        break;
                }
        case WM_DESTROY:
                {
                        PostQuitMessage(0);
                        break;
                }
        case WM_CLOSE:
                {
                        DestroyWindow(hWnd);
                        break;
                }
        default:
                {
                        return FALSE;
                }
        }
        return TRUE;
}

---

It breaks everything and gives me the following errors:

error C2143: syntax error : missing ':' before ';'
error C2143: syntax error : missing ';' before ':'
error C2046: illegal case
error C2043: illegal break
...etc

So, wtf is going on?

Probably WM_WTF is not declared.

It is, I just edited my post to show how it is defined.

Where is your WM_WTF defined and are you sure your switch can get to it?

It's defined in the same .c file that the switch is in.

It's defined at the top before anything else...

Well then my usefullness has run out, maybe post the real code if the above you posted was not it or post more code :)

>>It's defined at the top before anything else...

Sometimes that does not give it scope through the whole file.

Try define'ing it in an included header or at the top of the callback (and see if the problem persists)

or

do you have a conflict with a system defined WM_USER msg?

MSDN on WM_USER

"These values cannot be used to define messages that are meaningful throughout an application, because some predefined window classes already define values in this range. For example, predefined control classes such as BUTTON, EDIT, LISTBOX, and COMBOBOX may use these values. "

#define WM_WTF (WM_USER + 20))

You have an extra )

-edit-
unless......oh...it's in parenthesis, ahhahahahahahhaha

OMG IMM STUPID CUZ I DIDNT SE TAHT1111111 OMG LOL

I moved the #define WTF WM_USER + 20 to a header file and everything worked out.

Thanks all.

Code:

---

#define WM_WTF (WM_USER + 20)

---

Yet another reason why defines are to be avoided. This error would never have happened with a normal constant:

Code:

---

CONST DWORD WM_WTF = (WM_USER + 20);
