Hi

My app is a 4x4 splitter, with 4 Formviews (frmV1, frmV2, frmV3, frmV4), in frmV4 is a tab ctrl with 4 dialogs (dlg1, dlg2 dlg3, dlg4). Now in frmV1 I inserted a custom ctrl (KsVolumeDisplay)some time ago, and it has worked well, but now I inserted the control into dlg4 and used the class wiz to create a member var of type voulme display control, when I complie I get the following error msg

error C2011: 'CKsVolumeDisplay' : 'class' type redefinition

in 14 of my classes which points to

/////////////////////////////////////////////////////////////////////////////
// CKsVolumeDisplay wrapper class

class CKsVolumeDisplay : public CWnd   <<<<<<<This line

Now if I remove the #include "ksVolumeDisplay.h" from my dlg4.h it stops this error but of course I get
error C2079: 'm_xxxxxxxxx' uses undefined class 'CKsVolumeDisplay' (which I understand)
I don't understand why I'm getting the redefinition error and what to do to prevent it??

It seems that you are including the same header file more than once - do you have "multiple inclusion guards" in it, e.g.

//ksVolumeDisplay.h:
#ifndef __ksVolumeDisplay_h
#define __ksVolumeDisplay_h

// rest of the header file goes here...

#endif
