I'm creating an updater for an IP address, and I need to ensure that only one instance is running on the computer. This is to prevent (or at least make it more difficult for) having multiple tunnels running (it's an updater for an IPv6 tunnel).I've seen various ways of doing it in VB 6.0 and early .NET, but nothing that deals with .NET 3.5 or VIsual Basic 2010.

View 5 RepliesI wrote a programme and sent it to my client, (it was not a deployment or install file - just the .exe). He responded that it would not run and the PC reported "this program requires Net Framework 2.0". He cannot update the PC in question with Net Framework 2.0. So my question is can i somehow change my program to use an earlier version of Net Framework?

View 3 RepliesI was messing with my program as I was having trouble getting it installed on machines without VB Express installed already.

View 11 RepliesI have a program that runs some data manipulation on a file when it is double-clicked and then displays this to the user.However, when I double click on the same file type of a different file it opens in a separate instance of my program instead of the same instance already running, i.e. some message that says would you like to reload file, YesNo, and then given the answer perform the action required.I have found some code to stop a second instance from opening, but this is inconvienient for the user to close out of the program everytime they want to view a new file.[code]

View 2 RepliesI wrote a simple auto login script to update my IP address on a certain website. Something really strange is happening now though. The first time I run the program, nothing happens. However, the second time I run the program, that instance will work fine. Then I look in task manager, and the first program is still running, using a whopping 50% of my CPU. I believe VB may be blocking off memory or something, as when two instances are running each is using around 25% of CPU. Then after the second one successfully completes, the first starts to use 50% again.
Here's my code below:
Option Strict Off
Public Class frmTest
Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

how to PROPERLY make a multi-tabbed or multi-window application that can handle file start requests.
For example, on startup my "Desktop Application" runs and sits there waiting for a task, either through the main menu, or for a file to display in a window. Now the problem is simple, how can I make this already running program load the dropped file (dropped on the executable (!)), instead of starting a new instance.
I understand I will have to check if the process is running, and if so, do some stuff with it. But the problem is passing the message to the active program.
Previously I used text files with paths/arguments in them, but I don't like the idea of the OS/program checking every 500 ms if a file is created in the "load this" folder...
Then I thought of sending a message using "Send Message", for example changing the text in a textbox and handle the "Text Changed" event, but is this reliable? Can any other program interfere with it?
So, basically I need the proper way of doing all of this. For example, Microsoft Visual Studio does this nicely, and no lag whatsoever...
