    strcmp returns always 0

    I dont understand, it always enters if().

    Code:
    #include <windows.h>
    #include <iostream>
    using namespace std;
    char WindowTitle[MAX_PATH];
    
    BOOL CALLBACK Enum(HWND hwnd, LPARAM lParam)
    {
            GetWindowText(hwnd, WindowTitle, 260);
            cout<<"1. "<<WindowTitle<<endl;
    
            if(!strcmp(WindowTitle, "Calculator"));
            {
                cout<<"2. "<<WindowTitle<<endl;
            }
    
        return TRUE;
    }
    
    int main()
    {
        EnumWindows(&Enum, 0);
    }

    So, to make this interesting, are you saying the window title isn't Calculator?

    Programming for 5 years, and still being caught out by the trailing ; huh?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
