#include <commctrl.h> gives me errors

Hey, I have a weird problem when I #include <commctrl.h>....

Here is what the compiler (MSVC 2008) tells me.

Code:

---

C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include\commctrl.h(19) : error C20
59: syntax error : 'return'
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include\prsht.h(97) : error C2065:

C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include\prsht.h(97) : error C2065:
 'LPFNPSPCALLBACKA' : undeclared identifier
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include\prsht.h(97) : error C4430:

C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include\prsht.h(97) : fatal error

NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual Studio 9.0\VC\bin

Stop.

Huh?


I should probably mention that this header gets included more than once, but in different compilation units (I think that is the right term).

Like so:

Application.cpp

Code:

---

#include <commctrl.h>

code...

---

Notebook.cpp

Code:

---

#include <commctrl.h>

code....

---

Have you <windows.h> included too?

Yeah in Application.cpp, but not in Notebook.cpp.

Are you saying I have to #include <windows.h> before <commctrl.h>?

EDIT:

Ok I just did that and it works now. :P

Why on earth do I have to do that?

You probably know this, but because you asked anyway, commctrl.h depends upon windows.h. :p

Ok, so it needs windows.h, but doesn't include it? LOL

Typical.
