Detect if Excel is installed (Views: 29)
Problem/Question/Abstract: In the application I am writing I need to get data from an Excel spreadsheet and then insert it into a database. I am going to automate Excel. What I would like to know is how I can detect to see if excel is installed, and if it is, what version of Excel is on the user's computer. How can I do this? Answer: { ... } var ClassID: TCLSID; strOLEObject: string; begin strOLEObject := 'Excel.Application'; if (CLSIDFromProgID(PWideChar(WideString(strOLEObject)), ClassID) = S_OK) then begin {application is installed} end else begin {application is not installed} end end; To get the version, just read Version property of Excel.Application: xls := CreateOLEObject('Excel.Application'); v := xls.Version; |
