Write binary data using javascript on the server

Question

I'm trying to output a PDF using server side javascript (ASP). The current method I'm using is:

xfile=Server.MapPath(lib.fso.GetTempName())
xf=lib.fopen(xfile,"wb");
lib.fwrite(xf,this.buffer);
lib.fclose(xf);
outB = Server.CreateObject("ADODB.Stream")
outB.Type = 1
outB.Open()
outB.LoadFromFile (xfile)
Response.BinaryWrite(outB.Read())
outB.Close()
lib.fso.DeleteFile(xfile);

This works, but requires write access on the server. Is there a way to do the same thing without writing to a file?

I havn't been able to figure out how to convert the string this.buffer into a array of byte that I can then write using Response.BinaryWrite without writing to a file first.

Answer 1

Why not simply use:-

Response.Write(this.buffer)

Assuming the codepage of the response is set correctly (I.e., its the same as in the Locale that the VBScript is running in) then Response.Write should do the same conversion that your StringToMultiByte is doing.

I suspect you've tried this and is hasn't worked. If so I really think you need to look into why that is rather attempt this strange usage of BinaryWrite. Currently your solution is going to kill your server.
