 Posted: Wed Apr 25, 2012 8:26 pm Post subject: Help with GetMenu |
 |
|
I want to use GetMenu to get the handle to a menu.
I want the handle to be shown in a message box.
I'm still learning C++ and I have everything running except I do not know how to get the getmenu's return value into my message box. How do I do this?
| Code: |
GetMenu(hookWindow); // HookWindow is the HWND for a RichEdit
// I'm not sure if I am using GetMenu correctly. Please correct me if I am wrong.
MessageBoxA(NULL, "Menu", "The GetMenu's return value goes here",0); // This message box already shows, I just need the return value to be in the text

GetMenu:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms647640%28v=vs.85%29.aspx
The return is HMENU which is just a handle to the menu. A handle isn't really important data to show in a messagebox since it is not going to be the same always. At most, you would want to check if the return was null.
| Code: |
HMENU hMenu = GetMenu( hookWindow );
if( hMenu == NULL )
{
// The handle has no menu..
}
else
{
// A valid handle was returned.
}

| Code: |
template <typename T>
std::string toString(T in)
{
std::stringstream ss;
ss << in;
return ss.str();
}

| Code: |
MessageBoxA(0, "Menu", toString<HMENU>(GetMenu(hookWindow)).c_str(), 0);

It gave an error.
| Code: | | error C2297: '<<' : illegal, right operand has type 'HMENU ' |

Make sure you are including everything you need.
