I have the following code in my ASP:<BR><BR> Set oCustomDLLs = Server.CreateObject("CustomDLL1.BinRead")<BR> vntStream = oCustomDLLs.readBinFile(strFile)<BR><BR> Response.Buffer = TRUE<BR> Response.Addheader "Content-Disposition", "inline; filename=" & strFile <BR> Response.ContentType = "application/pdf"<BR> Response.CacheControl = "public" <BR> Response.BinaryWrite vntStream <BR> set oCustomDLLs = Nothing<BR> Response.End<BR><BR>This code is the same as the example supplied by 4guys..<BR>However when I run it the standard association box appears asking me to associate the file with a product. I select AcroRD32 and all works ok. This association is asked everytime I try to open a PDF file this way. How can I set the association programmatically (I thought that was the function of the ContentType ?). If I remove the Content-Disposition then I am not asked to select an association but a blank page displays (ie the PDF file is not displayed)<BR><BR>Thanks<BR>
