Hi,

We have an application in ASP.NET windows,where we pass user credentials on button click to a web application page.We need to retreive the passed varaiables in the page load of the web page.

We passed the varaiables in the below mentioned format through windows application.
string strUrl = "http://localhost:50541/ZenjICTCTransaction/Login.aspx?UserID=" + tbUserID.Text + "&Password=" + tbPassword.Text + "";
Process.Start("iexplore", strUrl);

In the login page we need to get the varaibale values.We tried to retreive using

VB

Dim UserID As String = Request.Form("UserID")
        Dim UserPass As String = Request.Form("Pasword")

But the value is not getting.

Please help

Try to use Request.Params("UserID")

But how you are trying to implement the authentication is not good way. We should never send password as query string.

Hi,

If your passing data by appending it to the url, you would use the Request objects QueryString[^] method to retrieve the values.

Have look at this article for some more examples Passing variables between pages using QueryString[^]

To use the Request.Form Collection[^] example you posted, would require you to add the values to the form collection, and then post the form.

... hope it helps.

Hi,
The URL in the code snippet you posted is an ASP.NET aspx file?
It doesn't matter what built the request to that page, the value will be available in the QueryString?

Why can't you use:
Dim UserID As String = Request.QueryString("UserID")

That sounds like a different question/problem ...

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack
Dim UserID As String = Request.QueryString("UserID")
End If
End Sub

What happens when you set a break point on If Not Page.IsPostBack?
