Scenario - I have a web application that generates Excel documents that can be downloaded or opened directly. The web pages are a mixture of both ASP.NET and Classic ASP so the Excel file is actually generated as an HTML table. When a Save or Save As operation is done when the .xls file is downloaded a specified file name passed from the web page is used in the save operation. When you open the Excel file after saving Excel displays "The file you are trying to open "filename.xls" is in a different format than specified by the file extension...Do you want to open the file now?" informing me that the file is not a true xls file. When you continue with the opening the file it opens normally with no issues.
Question or Possible issue: Taking one of these files after it has been saved to a location on the computer outside of the download folder, and perform a Save As operation to change the format to a true .xls file the theExisting File Name is not displayed in the File Name field. The Save as type defaults to Web Page which is understandable due to how the file is generated.
I've tried this with actual Excel spreadsheets and the File Name field on the Save As operation is populated with the current name of the file and keeps it even if you change the Save as type.
Main Question: Is there a setting somewhere in Excel to prevent the loss of the File Name?
