Question

I create a hyperlink that when clicks generates a url like so:

http://somesite?MyTag=C++

And I read it into a text box like so:

Me.txtTags.Text = CType(Request.QueryString("Tag"), String)

But the result of this is that the textbox txtTags will only contain C and doesnt have the ++.
I tried http://somesite?MyTag=C# and the # is missing as well.
But if I look at the address bar these values are there….

You need to use UrlEncode when you building url and UrlDecode when you are trying to read url params

MyURL = "http://www.contoso.com/articles.aspx?title=" & Server.UrlEncode("C#")
