Save An Excel File Programmatically?

I'm trying to import data from an Excel file into SQL server. However, the Excel file's format is not recognized by SQL Server. In fact, when I open it and try to save it, I get the following message:<filename> cannot be saved in the current format. To save your changes, click OK, then save it as the latest format.When I do that manually, it puts it in a usable format. However, the automated process I'm trying to build can't save it without intervention. When the VB in my SSIS process gets to it it brings up a save window, and I have to click the "Save" button and then the "Yes" button to replace the existing file. I'd strongly prefer to have this automated. I've have tried using the SendKeys.Send("{ENTER}") code, but it brings up this message:SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method.I've tried SendWait, but it just seems to hang. I don't know how to change the application to handle error messages. I have also tried saving the Excel file as a new file with my VB code. However, as a new xls, xlsx, and csv file it still wasn't recognized by the import. I've only had success when manually saving it. In the SaveAs code I have been using, I'm only using the FileName parameter. I can't get any FileFormats to work or be recognized. Note, though, I'm opening the app and worksheet as Object variables. I can't add the Excel component in the Add Refrence area because only the .NET tab is there. I don't have a COM tab. I haven't asked if/how to get access to it, though.
