I am getting this error message, Syntax Error, ':' expected, on the following line of code:

Response.Redirect("Launch.aspx"?FileName=" & FileName & "");

Anyone any ideas how to solve this?

Thanks.

Hi JMcCon,

You need to concatenate the string correctly, it's easier to spot errors if you break it down a bit:

string url = string.Format("Launch.aspx?FileName={0}", FileName");
Response.Redirect(url);

You are using & instead of + and you have one " to much.

Hope this helps

Response.Redirect("Launch.aspx"   **?   ** FileName=" & FileName & "");

You use the ?: Operator, but without the :. Therefor the error occurs. But the ?:-operator requires a bool at the left side of the ? ... And strings are added together by using +...

Response.Redirect("Launch.aspx?FileName=" + FileName); //Maybe this fits your needs
