   Hi all,

My application used a user-defined number of cameras (minimum 1). The user can pick from a commandbar the active camera.

To populate the commandbar, i use:

BOOST_FOREACH(ICamera* camera, cameras->Collection()) {

   CXTPControl* pCameraItem = pControls->Add(xtpControlButton, ID_CAMERA);

   pCameraItem->SetCaption( camera->Name().c_str() );

   pCameraItem->SetChecked( camera == cameras->Active() ); 

}

The listen to the commands, i use:

ON_COMMAND(ID_CAMERA, OnCamera)

and 

void CPyroView::OnCamera()

{

   // what camera is being picked?

}

Question: all the controls in the commandbar have the same id (ID_CAMERA) - in OnCamera i can't make the distinction between what camera is picked.

What is the correct method to use, when the amount of camera's is unknown (iow ON_COMMAND_RANGE cant be used)

Thanks

Bart

	Hi, Add pCameraItem->SetTag( iIndex) Remove ON_COMMAND and insert this line ON_XTP_EXECUTE(ID_FILE_RECENTPROJECTS, OnCamera) void CPyroView::OnCamera(NMHDR pNMHDR,LRESULT pResult) { CXTPControl pControl = ((NMXTPCONTROL )pNMHDR)->pControl; if (pControl) { DWORD_PTR myIndex = pControl->GetTag(); // do yours } } Jimmy

	Or pCameraItem->SetTag( (DWORD_PTR) camera ); ICamera* camera = (ICamera*) pControl->GetTag(); Jimmy

	Also can use CXTPControl CPyroView::GetControl(CCmdUI pCmdUI) { if (!pCmdUI->m_pOther) return NULL; return ((CXTPCommandBar)pCmdUI->m_pOther)->GetControl(pCmdUI->m_nIndex); } void CPyroView::OnUpdateCamera(CCmdUI pCmdUI) { if (m_dwMenuLock & ML_ANY) pCmdUI->Enable(FALSE); else { CXTPControl* pControl = GetControl(pCmdUI); if (pControl) { ICamera* camera = (ICamera*) pControl->GetTag(); pCmdUI->SetCheck( (camera->Active()) ); } else pCmdUI->Enable(FALSE); } } Jimmy

	Thank you Kimmy - i'm trying the latter, but bump into undefined "m_dwMenuLock" & "ML_ANY". I searched the library, but could find any reference to it. Will the last proposal also be capable of checking the active camera? (only active camera is checked, the other arent) Thanks again for looking inito this Bart

	(Jimmy - sorry for misspelling your name) (I commented m_dwMenuLock & ML_ANY) I got this to work: //--------------------------------------------------------------------------- // //--------------------------------------------------------------------------- // void CPyroView::OnCamera(NMHDR pNMHDR,LRESULT pResult) { CXTPControl pControl = ((NMXTPCONTROL )pNMHDR)->pControl; if (pControl) { ICamera* camera = (ICamera)pControl->GetTag(); assert(camera); camera->Activate(); } } //--------------------------------------------------------------------------- // //--------------------------------------------------------------------------- // CXTPControl CPyroView::GetControl(CCmdUI pCmdUI) { if (!pCmdUI->m_pOther) return NULL; return ((CXTPCommandBar)pCmdUI->m_pOther)->GetControl(pCmdUI->m_nIndex); } //--------------------------------------------------------------------------- // //--------------------------------------------------------------------------- // void CPyroView::OnUpdateCamera(CCmdUI pCmdUI) { //if (m_dwMenuLock & ML_ANY) // pCmdUI->Enable(FALSE); //else { CXTPControl pControl = GetControl(pCmdUI); if (pControl) { ICamera* camera = (ICamera*) pControl->GetTag(); ASSERT(camera); pCmdUI->SetCheck(camera->IsActive()); pCmdUI->Enable(camera != NULL); } else pCmdUI->Enable(FALSE); } } Thanks! Bart
