[Solved] Function doesn’t return correct TCHAR [closed]

by


Try this:

std::basic_string<TCHAR> MainClass::GetString()
{
    TCHAR name[256] = {0};
    int len = GetWindowText(hWnd, name, 256);
    return std::basic_string<TCHAR>(name, len); 
}

Or this:

std::basic_string<TCHAR> MainClass::GetString()
{
    int len = GetWindowTextLength(hWnd);
    if (len == 0) return std::basic_string<TCHAR>();
    std::vector<TCHAR> name(len+1);
    len = GetWindowText(hWnd, &name[0], name.size());
    return std::basic_string<TCHAR>(&name[0], len); 
}

Either way, then you can do this:

std::basic_string<TCHAR> name = GetString();

Alternatively:

int MainClass::GetString(LPTSTR name, int maxlen)
{
    return GetWindowText(hWnd, name, maxlen);
}


TCHAR name[256];
int namelen = GetString(name, 256);
