I managed to sort that problem out all by myself! I'm getting good at this. I just wonder if one of you could possibly tell me how to loop? I need to create a loop that counts up the a balance in a database then adds it together?
View 3 RepliesI am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.
View 5 RepliesA few years ago I have been busy creating this application but it didn't succeed, now Im coming back to it and similar problems occur. Basically I use SetPixel on a given window to draw a line, work fine, but the line goes away as the window redraws itself.The problem: I have been putting timers and threads on it to make sure the line is being drawn. Is there any way to make a loop to make a certain thing happen about 10-30 times without taking in too much memory/CPU?

View 1 RepliesHeres my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code].....
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.

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.
VB.NET While 1 = 1
Dim localRecv As New StreamReader(localClient.GetStream)
Dim aString As String = localRecv.ReadLine
localRecv.Peek()
MsgBox(aString)
End While
Basically "aString" will keep updating if new data arrives to the server. This way does work, and keeps MsgBoxing every time I get new data, but I don't wanna use While, I need something else, because It won't run any other code, just keeps looping that. :/

View 3 RepliesI need an additional loop argument within an If statement that resides in a very large do...loop block. It will speed the application considerably if I can have the do...loop block loop prematurely. I already have the remaining code after the additional loop argument in a large if...elseif block to achieve the result, but making it simply loop instead of going through this would speed the application.

View 14 RepliesBasically what i need is for something to look at the items in a list box then compare it to the contents that is in the database. The issue is that the listbox can have more than one of the same item. For instance, LstBox_Order.items(0) could be the same at any position in the listbox. This code works, but it is slow if there is like 10 or more items added.

I am creating a button to save text files (Visual Basic 2005 and Windows XP). I made the following loop to give a default name for the file before saving:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'This loop is supposed to name the file "file10.txt", and if such a file exists it is
supposed to name it "file20.txt" then "file30.txt" etc.
Dim myFileName As String
Dim i As Integer = 10
myFileName = "D:filesfile" & i & ".txt"[code].....
However, the app gets unresponsive only after one round in the loop (when the file name is "file20"). The loop gets stuck at the following line:
If IO.File.Exists(myFileName) = True Then
This line works only once and after that it becomes unresponsive.

I have made a For next loop with an array. I want all my picture boxes to follow each other within the loop. I have currently been using old code, but not in a loop or array format. The old code works. The array code only makes the 2nd picture box follow the FIRST one. It doesn't loop the rest. I have checked the code and cannot determine any mistakes, else I'm missing out on something I haven't been taught.[code]...
