How To Make Infinite Loop

Jul 12, 2009

1) Diff b/w nothing & string in terms of variable declaration.

2)Erase keyword.I have never heard of such keyword in mine whole 1 + yrs of exp.

3) Diff b/w functions & properties? I say,Functions return a value,But propertiesare used to set or get the values. He say properties also return a value.

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, 2009

I 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.

Infinite Loop And Cross Threading?

Jun 22, 2011

I 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

Draw And Paint Without Creating Infinite Loop?

Dec 10, 2010

I wanted to draw a chart on a picture box. So I create a form, put a picture box on it, and then in the code of Form_load, I put a handler to the paint event of the picture box. This seems to create an infinite loop, judging from the behavior of the form.

DataGridView Check Record Count - Infinite Loop

Jul 26, 2010

As 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.

MIS
For Each item As DataGridViewRow In dgvLaser.Rows
If IsNumeric(item.Cells(3)) Then
Exit For
Else
MessageBox.Show("Check Record Count. Numerical values only..!")
End If

VS 2008 Internet Browser Shortcut With Infinite Loop

May 12, 2009

So 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, 2010

I'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?

How To Use Infinite Loops In Event Listener

May 1, 2012

I 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, 2011

Makes 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.

Option Strict On
