<%
Dim cFlavor, cName
cFlavor = Request("Flavor")

string cPostData = "FName=Allan&Flavor=Vanilla";
SomeBytes = Encoding.UTF8.GetBytes(cPostData);
WebBrowser1.Navigate("http://localhost/Navpost.aspx", "_self", SomeBytes,
        "Content-Type: application/x-www-form-urlencoded\n\r");

Solution 1

Everything looks fine, except that '\n\r' should be '\r\n' or just use Environment.NewLine

Solution 2

Thank you for noticing the CRLF was backward; I got this code from a web-site. However, correcting the CRLF didn’t help. The original code was written for Visual Studio 2005 and I’m using 2008, so I had to change the arguments for the Navigate class since the new .NET version didn’t have the older set of arguments.

Are you getting any exception ? try catching the following exceptions 1) ObjectDisposedException 2) InvalidOperationException. or check if your ASP.Net application security is on FullTrust.

I don't see any other problem with this.

Thank you. I'm using UriFormatException and InvalidOperationException for the Navigate class try/catch, but the compiler did not like ObjectDisposedException. None of these execeptions are being called. I’m using an Apache server for my localhost; how would I check if the ASP has a security issue?

When I started to do research on my new automobile, I came across this page that showed me everything I needed to know about how to purchase a new car. There are more ways than you could think of that the dealership makes money off of every sale; doc fees, holdbacks, finance charges, and so many more. I went to this web site and they sent me FREE information on how to negotiate with a auto dealer and how to purchase a new car below invoice. After reading everything that they sent over to me, I was much more educated on the buying process and wanted to share that with all of you. I simply printed the eBook, brought it to the dealership, and I walked out of there paying less than invoice. If you are in the market for a new car, this is some must read information and it is FREE. Take a look and please post any other advice you might have to help others who are buying a new car.
