How To Make Infinite Loop
Jul 12, 20091) 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.

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.
View 3 RepliesInfinite Loop And Cross Threading?
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.
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, 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?

Write A Loop That Will Read Through A Number Of *.csv Files In A Folder?
Feb 21, 2010Im trying to write a loop that will read through a number of *.csv files in a folder and then stuff the data into SQL. The code works and will happily put the data i want for a named file into SQL no problems. So when i had that working i then tried to loop it so that it would do the same for all files in the folder until all files had been done, and not error out if there where no files etc.
Maybe im tired (well, i am) or not had enough coffee but i just cant get this to work, it should be simple - i know it is infact, but its making ME feel simple.i think i should have an integer count in there, but similar examples ive seen dont use one. Also when trying to open the path i get an error at runtime "the path is not of a legal form"
code:
Public Sub ImportCUSTCSVs()
Dim dt As New DataTable()
Dim line As String = Nothing[code].
