VS 2008 : Loop Works With Breakpoint Only?
Mar 26, 2009I have written a pontoon game for a college project but i have a problem in which my loop only works when there is a breakpoint in it.The counter is incrementing as i have used a msgbox to display it. The procedure runs the loop and returns the same value in all locations in the array. With a breakpoint it displays correctly in the array.
here is the
Dim aryCardValue(0 To 10) As Short
Dim aryCount(0 To 10) As Short
Dim i As Short
[code]....
I have used the cards procedure in other programs and it worked fine.
Make Loop In Program And Calculate Time Taken To Complete Loop?
Nov 23, 2011I 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 RepliesEvaluates 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.

How For Each Loop Statement Actually Works
Dec 8, 2011I am trying to understand how a for each loop works and am having some trouble. I am trying to create a program that will query a sql database, pull back the information and store it. I currently having it writing to a text file, and would like to take the information (such as name) and compare it to another list where the name is equal. However I am not exactly sure how the for each statement really works. I have looked at numerous sources and it doesn't make since to me as you can probably see from what I have put in here.

VS 2010 : HttpWebRequest In A Loop Works Only Once?
Jan 5, 2012I�ve had success using the GET method to retrieve a series of web pages but my new challenge requires me to use a POST > GET combo. I can get it to work once just fine but no more. I get the feeling that something isn�t closing or completing properly. When I try to do the second GetRequestStream() I can see from my sniffer app that nothing is being sent so when the next command to stream the POST data to the request session it fails. I removed it all from the loop and simplified it as much as possible. Can someone tell me why it fails?
Also as a general question is my tack or reusing WebRequests viable? Or is there a �best practice� for looping a POST > GET combo? I�ve been assuming that since nothing in the WebRequest changes besides the post data I�m sending, even its length remains the same, that I should be able to re-use it.
Dim Cookie As New CookieContainer
Dim encoding As New UTF8Encoding
Dim byteData As Byte()

Note: The section after the �Experimental comment is a surrogate for the second iteration of the loop. The GET that normally follows the POST section has been removed.
IF Works But Loop Required - Huge Network With 20+ File Servers All With Data Spread Out Across Them
Mar 4, 2011My app is a fairly simple and im sure with the right knowledge this would take 2 minutes.. but sadly iv been at it for hours. So my scenario here is a huge network with 20+ file servers all with data spread out across them it can take hours to find the folder required.
Hence this app.. so it consist of a input box, progress bar and a button, using FileSystemObject I plan to interrogate a directory to see if a folder exists (folder specified by user input) however it need to check multiple directories, in my old app I used a list box which wrote to a text file allowing the user to add additional directories then using if statements proceeded through the servers.. however they have added that much that my IF's have ran out really because i know it should have been a loop

CODE - For Next Loop - Program To Display The Most Active Year For Storms Between The Years 1990-2008
Sep 23, 2010The program I am working on uses arrays and a text file. In one section of the program it's suppose to display the most active year for storms between the years 1990-2008. The year that has the most active storms is 2005, but I don't know how to write it in the code so that it displays. Attached is the text file.
So far I have a For Next loop that counts the arrays.

Apr 16, 2012CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
Create A Loop To Loop The Locations Of The Platform?
May 31, 2010So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:

While Loop - When Running The Debug The Program Crashes
Mar 15, 2012I've been having a bit of a problem using the while function.
Here is my code (Simplified):
Dim RandomNumber3 As Random
Dim RandomOutput3 As Integer
[CODE]..............
When running the debug, the program crashes, and when I step into the program, I find that this While statement becomes an infinite loop. This is a program that uses random number generators to assign a value to something, and this while statement is necessary so that there is never two of the same values showing (RandomOutput, RandomOutput2 & RandomOutput) Have to be different to one another.
