Oct 13, 2010I use Visual Studio 2003, VB.net, NetFramework 1.4 and Windows XP I have been using the following Code Snippet for a number of years in both Web Services and Windows Applications.

Make Function Not Generate 'doesn't Return A Value On All Paths' Warning?
Oct 22, 2010I have a function to recursively search through windows (and their child windows) to find specific ones, it works exactly as expected, however it causes "function doesn't return a value on all paths" warning. This is the only warning in my entire program, and although it might be silly, I'm interested in knowing if there is a way to stop this error from occurring, but still allowing the function to work properly.[code]

Multithreading Webrequests To Update A RichTextBox Form Control
Mar 1, 2011This probably shouldn't be too hard for someone to answer...even though I've spent 2 days trying to get it right. ::sigh::
I have a RichTextBox1 on my form. I need it to update every half second pulling HTML off of my webpage. I USED to have it update every half second with timers but everything keeps getting clogged and I realized I have to multi-thread.
My code so far is
Imports System.Threading
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
(This is an example of code from the bigger project) So I guess my question is how do I send out about 10 of these threads (Will the sleep suffice? Or will that just pause everything making it inefficient for multithreading at all and basically turn it into a timer), and what is the proper way to make the thread post the 'responseFromServer' to the RichTextBox1 in a safe way?
I can't get it to post at all because I know there's some invoke trick I can't figure out so I don't cross the threads like in ghost busters, and also if multiple threads are trying to post to it at once I'm going to need a protected way to do this.
Asp.net - Adding A Session ID To A Link For Automatic Session Start?
Dec 8, 2011I am storing a session variable that a user types into a textbox. With their valid input, their session gets created and they get a little more functionality than the regular end users of the site.I was wondering if it is possible to find a way to add someone's session variable to the end of a URL. This way we can email a link to one of our clients, they click it, and their session has automatically begun. They already have the textbox to enter their code into, but I was told that it would be much easier for the users to just click a link that will start their session.

Dim userID As String = Session("UserID")
This is just a page in asp.net. I want to be able to grab the Session("UserID") but every time I try, I get this error:
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \ section in the application configuration.
If I put that Dim userID inside say the Page_Load Event, then it works fine. Why does it have to be inside an event? I want to dim it once, and use it throughout the page.

Asp.net - Using Session Variables In IE?
May 14, 2012I have an ASP.NET application that I am developing. I'm using session variables within the app.In Firefox & Chrome, they all work.But in IE (ver 9), there's one variable that's not working. I'm not sure if it's a storage or a retrieval (or both) at this point. The variable in question that I'm storing is a List(T) type. It's the only one of it's kind that I'm using. Can't help but think there's a correlation there.One other old post mentioned the possibility that cache is causing the problem, but I didn't understand the answer very well.

PHP Session When Using Desktop App?
Apr 11, 2010how to POST to a php file form a vb.net app: http:[url].... So now I've logged in the user user by posting their username and password to the php file, the php file then does security/checks they exist/etc and if both username and password are correct is stores the user ID in a session variable.Now if the vb.net app tries to download data off a page which needs the user to logged in, it checks this by doing:
if (!isset($_SESSION['uid'])) {
header("Location: index.php");
}
However after having logged correctly in the app the session variable is not set.How does session work with a vb.net app like this?When the user logs in successfully should I download the user id and keep it in the vb.net app and then post it to each page that requires authentication?

Session Timeout In ASP.NET
Jun 7, 2010I have written a page with an iFrame that basically cycles through a series of internal pages on our server displaying daily activity for our company. The problem I think is that it sporadically loses its session and redirects back to the login screen to keep losing its session which is the default behavior for anyone on our site trying to access a webpage without being logged in.
I have set the session timeout to 4hrs, the iframe cycles through 6 pages anywhere from 10 seconds to 5 minutes on each, and I have even set the META refresh on the page to refresh every 3 hours. I don't understand what else could possibly stop this page from staying active.
