lcFile = oApp.GetProcess("Transmit") oApp.oResponse.ContentType = "application/x-unknown" oApp.oResponse.AddHeader("Content-Disposition", "attachment;filename=" + lcFile) oApp.oResponse.TransmitFile(cCacheFat + lcSubDirectoryFat + lcFile)It seems the browser is doing something to the file which makes it unreadable by Word and Excel. In Word, an error about an incorrect document syntax is thrown. In Excel, an unknown error is thrown. Can someone explain why I have no problem opening those XML files in Word or Excel from the Windows Explorer but can't from the browser?
