Have you hit the chUser.asp page to see if the XML looks well formed?

Repost your sample app using the "Attach Code" function and I will run it to see what is the matter.

Hi Tracy,

Thank you for taking interest in my prob, herewith I am attaching the code for
MXML file and chUser.asp file

following is the code for chUser.asp


<%@LANGUAGE="JAVASCRIPT" CODEPAGE="1252"%>

<%
Response.ContentType = "text/xml";

var userid = Request.Form("Uid")
var password = Request.Form("Upass")
var flag = false;

if(userid=="guest" && password=="guest")
{
flag=true
}
%>
<valid>
String(flag)
</valid>

Ok, you had several problems.
First, use the asp I modified but change the output line to this:
<valid><%=String(flag)%></valid>

When the string is output on several lines there will be embedded carriage
returns and tabs and such that will make the value of the valid node something
like \r\ntrue\n\r, which will make your conditional not work

Second, The url in the HTTPService is not correct. the asp file must be served
from an IIS site, so there is no way the filename will work for a url, you need
the full url to the asp file:
url="http://localhost/MyIISApp/chUser.asp"

Third, there were problems in your result handler. You were passing in the
event object but treating it like it was the result object. Since you specified
resultFormat="xml" your result object is an XML document. You were trying to
access it using dot notation which will not work with an xml node.

Here is the modified mxml app:

Obviously you need to change the url to match you IIS site.

Dear Tracy,
I am really thankful to you, the code you give me is really works and now i
know that where i am wrong.....

i need one more help from you is,

i logged in sucessfull then i want to how I can show a new form to user?
should I Hide the login Form and visible a new form or is there any other
way.... please I am new to this field, so help me..

Thanking you,

kalpesh patel

Typically, this is done with a mx:ViewStack. Put the login form at the "0"
index of the ViewStack, and when the login is successful, set the
ViewStack.selectedIndex to whatever view you want.
