对于MFC
COleControl::AmbientUserMode
Determines if the Container is in design mode or user mode.
BOOL AmbientUserMode( );
Nonzero if the container is in user mode; otherwise 0 (in design mode). If this property is not supported, this function returns 0.
For example, a container might set this to FALSE in design mode.
根据当前ActiveX控件当前所处的模式，修改OnDraw函数：
BOOL bUserMode = FALSE; bUserMode = AmbientUserMode(); if(bUserMode) { LPCTSTR pszText = _T("MFC 3.0 : User Mode"); TextOut(di.hdcDraw, (rc.left + rc.right) / 2, (rc.top + rc.bottom) / 2, pszText, lstrlen(pszText)); } else { LPCTSTR pszText = _T("MFC 3.0 : Design Mode"); TextOut(di.hdcDraw, (rc.left + rc.right) / 2, (rc.top + rc.bottom) / 2, pszText, lstrlen(pszText)); }
对于ATL
Retrieves DISPID_AMBIENT_USERMODE, a flag indicating whether the container is in run-mode (TRUE) or design-mode (FALSE).
HRESULT GetAmbientUserMode(BOOL& bUserMode);
The property DISPID_AMBIENT_USERMODE.
One of the standard HRESULT values.
OnDraw中判断
BOOL bUserMode = FALSE; HRESULT hr = GetAmbientUserMode(bUserMode); if(bUserMode) { LPCTSTR pszText = _T("ATL 3.0 : User Mode"); TextOut(di.hdcDraw, (rc.left + rc.right) / 2, (rc.top + rc.bottom) / 2, pszText, lstrlen(pszText)); } else { LPCTSTR pszText = _T("ATL 3.0 : Design Mode"); TextOut(di.hdcDraw, (rc.left + rc.right) / 2, (rc.top + rc.bottom) / 2, pszText, lstrlen(pszText)); }
判断ActiveX控件是Desgin Mode还是Runtime Mode
