(1) Common mistake when working with code behind classes.
Remember! Codebehinds arn't handled the same way as inline/ pages!
You need to declare EVERY control you want to interact with in the codebehind class
Do this just after the Inherits statement:
<code>Public Class PageOne
Inherits System.Web.UI.Page
Protected WithEvents litOne As System.Web.UI.WebControls.Literal
...</code>
(2) Bad Scoping.
<code>Sub Page_Load(ByVal e As System.EventArgs) Handles MyBase.Load
Private strHello As String
End Sub
Sub Button1_Click(ByVal e As System.EventArgs) Handles Button1.Click
strHello = "Hello!"
End Sub</code>
(3) bad inits and constructs:
Remember, some classes have constuctors
Consider DirectoryInfo:
<code>Sub Page_Load() ....
Dim dirInfo As System.IO.DirectoryInfo
dirInfo.GetDirectory("C:\")
End Sub</code>
In the above example, we've only defined dirInfo *AS* a DirectoryInfo class, we haven't actually created it
So we need to do this instead:
<code>Sub Page_Load() ....
Dim dirInfo As System.IO.DirectoryInfo
dirInfo = New System.IO.DirectoryInfo("C:\")
End Sub</code>
That should do it....
Remember, ALWAYS refer to the MSDN Library when enquiring about classes and their initilisation (sp?) methods.... why trust some "1337 script kiddie!" site when you've got the official reference at http://www.msdn.com ? Or better yet, get the compiled version on CD, don't need to worry about long download times or the constant "was this article of any use to you?" screen.

Hi
I'm trying to create a website with a logon screen and two parts, a public area and a member area. The first page will be the public area. The user then clicks login and is directed to a login page which checks logins with a database. Once the user is logged in they need to be directed to a sharepoint site. Here is my problem...I need the Sharepoint site to use the login info from the login page. I would imagine Sharepoint uses session variables to store the login info, does anybody know what these are?
Thanks
Scott

Request.ServerVariables("REMOTE_ADDR")
or
Request.ServerVariables("REMOTE_HOST")
should both give this.

OK.. try using:
Dim ip as string = Request.UserHostAddress
|
|
|
|
|
HI
I tried this it gives me following error.
Microsoft VBScript runtime error '800a01b6'
Object doesn't support this property or method: 'UserHostAddress'

Well this is an ASP.NET forum, not VBScript... I suggest you try Googling "client ip address vbscript" and follow up some of the results...
|
|
|
|

I know this is asp.net forum i have implemented same application using asp.net also when i run the application on local machine it gives me correct ip address
and when i am upload this to server and run the page then it also show me
server ip address and server name insted my machine name.
Ok thanx for u r help.

Ths may help: (you'll ned to convert ot VB)
string ip;
ip=Request.ServerVariables("HTTP_X_FORWARDED_FOR");
if(ip==string.Empty)
{
ip=Request.ServerVariables("REMOTE_ADDR");
}
REMOTE_ADDR does not always provide the users IP but rather the ISPs' IP address so first test HTTP_X_FORWARDED_FOR as this one is the real user IP.

|
|
|
|
Thanx
I tried that but the result is same as before.Is there
any server setting required for that purpose.
Thanks.
Rahul

Try this code:
Request.ServerVariables["REMOTE_ADDR"].ToString();

Could you please elaborate Where you have hosted your web application. Its localhost or outside ur network??
|
|
|
|
|
The web application was hosted on a dedicated server that was accessible locally, or from intranet or over internet. the IP could always be requested in the way I explained some post earlier.
However, this was a long time ago, on a different .NET version that today's.
Hope that helps...
