Hello.

class MUXDLL_EXPORT CMuGridCellEditStr : public CExtGridInplaceEdit

This class is virtual in CExtGridInplaceEdit.
By this program, I want to judge the input character.
For example, DeleteKey or numerical value.

Please teach a sample code.

Then I cannot catch VK_DELETE.

With the following CODE, a message does not flow.

bool CExtGridWnd::OnGbwBeginEdit(
 LONG nVisibleColNo,
 LONG nVisibleRowNo,
 LONG nColNo,
 LONG nRowNo,
 INT nColType,
 INT nRowType,
 const RECT & rcCellExtra,
 const RECT & rcCell,
 const RECT & rcInplaceControl,
 bool bContinueMsgLoop, // = true
 __EXT_MFC_SAFE_LPCTSTR strStartEditText, // = NULL
 HWND hWndParentForEditor // = NULL
 )
{
 :
 :
 :
 :
	 if( (!bCtrl) && (!bShift) && int(msg.wParam) == VK_DELETE )
	 {
	  if( msg.message != WM_CHAR )
	  {
	   if( ! g_pEditCell->_OnQueryInplaceVkDeleteProcessingEnabled() )
	   {
		::PeekMessage(&msg,NULL,msg.message,msg.message,PM_REMOVE);
		continue;
	   }
	   LRESULT lResult = 0L;
	   g_pEditCell->OnInplaceControlWindowProc(
		lResult, msg.message, msg.wParam, msg.lParam, msg.hwnd, *this,
		nVisibleColNo, nVisibleRowNo, nColNo, nRowNo, nColType, nRowType,
		rcCellExtra, rcCell, rcInplaceControl
		);

The CExtGridWnd::OnGbwBeginEdit() will be invoked only if the WindowProc virtual method of your in-place editor control invokes the parent class’s WindowProc virtual method for WM_KEY*** messages.

The CExtGridWnd::OnGbwBeginEdit() will be invoked only if the WindowProc virtual method of your in-place editor control will invoke the parent class WindowProc virtual method for WM_KEY*** messages.

You should handle the WM_KEYDOWN standard message in an overridden WindowProc() virtual method.
