Hi all, I seem to have developed a strange problem with the TExcelApplication component.
Background. I have an application that takes data from a 3rd party application and bridges it to a series of Excel spreadsheets. The application uses a series of Jedi plugins, one for each of the spread sheets. I have shipped the Application and 2 plugins to our production office where it is running successfully. The Problem. Production wanted another spreadsheet so I have created another plugin, based on the previous 2, all runs well until I get the the WriteSpreadsheet routine, where for some reason I get an EIntfCastError when I try to connect to the Spreadsheet. I've also tried running the other plugins, but get the same error. I'm assuming that I have some problem with Excel itself, but have been unable to resolve it so far. Any help would be much appreciated. Paul Bennett
