Comparing two strings (not working)

[abdul]

I have hooked my window and I am trying to know when a menu window is created as a new window is created. The class for the menu window is #32770 (I think) so I am using the following chunk of code to check when a menu window is created:

LRESULT CALLBACK CallWndProc(int nCode, WPARAM wParam, LPARAM lParam)
{
    CWPSTRUCT *cw;
    string classname;
    switch (nCode)
    {
    case HC_ACTION:
        cw = (CWPSTRUCT*)lParam;
        GetTheClassName(cw->hwnd, classname);
    //    MessageBox(cw->hwnd,classname.c_str(),"",MB_OK);
        if(strcmp(classname.c_str(),"#32770") == 0)
        {
        MessageBox("A menu window was created","",MB_OK);
            //A menu window was created
        }
        return CallNextHookEx(myhook,nCode,wParam,lParam);
    }
    
    return CallNextHookEx(myhook,nCode,wParam,lParam);
}

void GetTheClassName(HWND hWnd, string &classdest)
{
    char classname[128];
    GetClassName(hWnd,classname, 128);
    classdest = classname;
} 

Now if I uncomment the line MessageBox(cw
>hwnd,classname.c_str(),"",MB_OK); before I use the if statement, some of the class names ARE "#32770" so it should actually return 0 from strcmpy but it's NOT. It never shows the message box inside the if statement which says "A menu window was created".
