问题 I've been working with Word2010.pas for the past week and everything went well, until I found out that if you open a document manually , edit it (but don't save), press Alt+F4 , a prompt will show up saying if you want to save your document or not, leave it like that. Go into code and try to access that document , all calls will result in EOleException: Call was rejected by callee . Once you cancel that Word save prompt, everything works fine.

问题 I am having a hard time making sure my COM objects are closing so I am not leaving an EXCEL.EXE process running in the background. I have learned that the double dot and chaining of declarations is bad as this could leave COM objects hanging around. Does anyone know how to fix this line of code so I can properly close and release the worksheet COM object? worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets[strName]; EDIT: I have tried using app.Quit() when I am done

问题 I am getting "There is a printer error." when tying to send a print job to a printer using automation on Windows 7 with Word 2010. Same code works fine on Windows XP box with Word 2007.

问题 I have this code that creates a new Visio document and adds a rectangle. It works, but I don't like having to open another document to get the Masters collection from it.
