VS 2008 Internet Browser Shortcut With Infinite Loop
May 12, 2009So I'm getting annoyed with this ffriend of min that keeps on asking for code off me for a VB assignemnt. Now I'd like to give him some code, but not the right code, (play a joke on him...he...he..). So thats the reason I'd like to write a infinite loop program for Internet Explorer. Would such Visual Basic program be possible?
I'm not going to write anything epic, but probably just the event handler to a button that keeps uploading internet explorer on a infinite loop after clicking. I know morally, this is wrong. I would rather be an ass than a lazy bastard.
VS 2008 - Infinite Loop - Event Triggered Keeps Firing Off The Code
May 9, 2010I'm not even sure what I need to know. None the less lets say I got a timer with an if event to check if said event is triggered then it fires off some code. The problem is if said event is triggered it keeps firing off the code and I only need to do it one time. Whilst letting the timer keep checking if event happened. I hope I worded that right and here is a rough translation in code. [Code] Is there a way to keep checking if an event happened and only fire off the code one time?

4)How can we use a class as a datasource?
5)Partial Class? hey frnds above question is for C++ na.Or there is also such class in VB.Net.
6)When the error stack overflow comes?
7) How we can we make indefinite loop , without uusing any variable declaration.
Infinite Loop - TCP Freezing With .NET?
Aug 12, 2009I made a game in VB .Net that uses tcp and sends messages back and forth.What is happening is, every so often, the message cannot be sent quickly enough, so then the TCPObj.connect() method goes into a loop, until it reaches the timeout and then spits out an error. Most of the time though, it never gets to the error, my application just freezes, and then comes back after TCPObj.connect() succeeds. How can I make the connect() method do application.doevents while it's trying to connect? Basically, I dont want it to freeze up my whole application. Since tcp.connect() is a .NET method, I can't go in and add application.doevents.

Jun 22, 2011I am a student attempting to learn VB.NET on my own. Today I wanted to tackle the BackgroundWorker component. I found an excellent article online: How To Use a Background Worker. I successfully completed the walkthrough and even performed the "adventorous" part that dealt with working with controls updating across threads using delegates.Now I came to a part that I didn't understand how it was working. To summarize the following code, I have a delegate that has a Label and a String in its signature. I then have a subroutine that is called on the worker thread. Inside this subroutine the delegate is created and (I guess) ran again so that it is on the same (Main) thread. Please correct me if I'm wrong here.
Here is the method is performed on the worker thread:
Private Sub My_BgWorker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles My_BGWorker.DoWork

DataGridView Check Record Count - Infinite Loop
Jul 26, 2010As you all know, If the dataBase requires a numerical value then an error will occur when the user tries to insert the incorrect data type. With the code below after the user types in a value beside an int value type then it will go into an Loop through more than what is needed. How can I apply the same logic but allow the program not to check the 60 rows (I set the row size to 60). I want to break out of it if there are blanks ONLY if a row is blank and not for a black cell, because if the user leaves one cell blank then it would loop through the 'for each' for how many rows that they is. Initially there are 60 rows.

For Each item As DataGridViewRow In dgvLaser.Rows
If IsNumeric(item.Cells(3)) Then
Exit For
Else

VBNet Equivalent Of AfterUpdate?
Feb 18, 2011One of the convenient and simple events I liked for textboxes in VB6 and VBA was the afterupdate event where after you finished typing in your data or text, you pressed enter and the program processed the text in the textbox. In VBNet, life is not so simple. I have included a simple code to do the same thing using the keydown event and checking to see if it is the enter key. This code just send a message box with all the text in it. You can manage things from there

VS 2008 : Infinite Undo/redo: How To Implement It
Apr 4, 2011basically add and remove text and selection information from a stack. Result: When using Undo/Redo the selection got messed up, the text moved, sometimes causing lag of epic proportions. I need a way of having complete and smooth undo/redo class for storing all information I would possible need.How to know whether or not to add an undo stack is easy, I just checked if the user clicked in the text or moved using the arrow keys. As soon a previous marking was given for "next text change needs to be backed up", it was backed up. At that point I stored the RTF and selection start/length. What do I have to store of a RichTextbox control to be able to restore it to a previous state, and how can I reset it back to a previous state? See it as having a "RichTextBoxState" class:
Public Class RichTextBoxState
Sub New(ByVal RTB As RichTextBox)
Me.text = RTB.RTF
Me.selectionstart = RTB.SelectionStart
[code]....
After restoring it must display the EXACT same thing as when it was saved as a state.

View 29 RepliesHow To Use Infinite Loops In Event Listener
May 1, 2012I am trying to build a small window component, which has two buttons.
When I click on the Start button, my code needs to establish the connection to server and keep checking the status (this is infinite loop, I have a boolean global variable which is set to true and based on this loop will work).
When I click on stop button, it should stop checking (I will make global variable to false).
I have code to check my server status.
However, since it is kind of infinite loop, moment i click on start, window form is not taking any other actions, since the control not coming out of event listener of start button.
I have many scenarios like this kind of infinite loops.
How to resolve this, what kind of approch should i follow in vb.
Evaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed
Mar 14, 2011Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

VS 2010 'Infinite' Public Instances Of A Class?
Jan 24, 2012I'm a little out of my comfort zone here having programmed in VB6 quite a few years ago things have changed a lot since then.My issue is I have a class that I've built which works with no issues but I would like to be able to keep a 'handle' of some description on this class so I can also make adjustments to it's parameters when the user changes something. My problem is that I need to do this for an unknown quantity of these class instances.
In the VB.Net language how would I create an instance of this class that could be accessed by any Sub within the application and each instance created can be individually accessed by specifying some sort of identifier?
Asp.net - Use Session Variables To Prevent Infinite Web Form Popups?
Apr 6, 2012I have a web application that allows a user to view family members.
When the user clicks on a family member, it displays the member's basic info. There is also a grid displaying that family member's related family members. (e.g. User can click on the Father link. From that popup, they can then click on the Father's Father link, then click on the Father's Father's Grandson link, etc.).
To reduce the number of popups that appear on the screen, I want to prevent the user from continually clicking on family links past three members.
What is the best way to keep track on how many data forms have popped up? Or can this reliably be done with a web application?
