Another idea: Use two temp memory image(first is display,second is create in memory; change them when second is ready).

CDC::GetTextExtent BOOL ok = FALSE; int richeditwidth = CRichEditCtrl::GetRect get richeditwidth CFont font = CRichEditCtrl::GetFont do{ 1.CDC::GetTextExtent get stringwidth 2.if(stringwidth < richeditwidth) { ok = TRUE; } else { font size -- CRichEditCtrl::SetFont } }while(!ok); hope this can help u .

1.Word eg: you can rewrite the sub of "save" in VBA template file: Sub FileSave() 'ActiveDocument.Save End Sub 2.word eg: set enble property: activedocument.CommandBars("File").Controls(5).Enabled = False 'office2003

1.Modify like this: [out] BSTR* pawSuggArray 2. "SAFEARRAY" maybe also can do this.

you can use share memory when sharing data between EXE and COM or between COM and COM: CreateFileMapping OpenFileMapping MapViewOfFile

char str[] = "abcdef"; int iSize = strlen(str); BYTE * pByte = (BYTE *) str; CByteArray arr; for (int i = 0; i < iSize; i++) { arr.Add(pByte[i]); } the loop is must use.

ClassLib, A C++ class library: http://www.codeproject.com/KB/library/classlib.aspx[^] the "MDI" Sample maybe you need.

also you can do like this: PRINTDLGEX pd; LPPRINTPAGERANGE ppr=NULL; .......
