Simple Recursive Loop Programming Task

Apr 19, 2010

I am an intermediate programmer with a basic understanding of VB.NET, however, I am having a problem with a special loop named "recursive".

To select the 3rd subitem/node inside a control named "CrumbBar", I have to:
CrumbBar1.SelectedItem = CrumbBar1.Items(0).SubItems(0)
CrumbBar1.SelectedItem = CrumbBar1.Items(0).SubItems(0).SubItems(1)
CrumbBar1.SelectedItem = CrumbBar1.Items(0).SubItems(0).SubItems(1).SubItems(2)

And go through all items, but I need to do this in a LOOP. And I don't know how many nodes I will have to go inside. So I wanna know how can I loop the above code?

.net - Recursive For Each Loop Doesn't Seem To Recurse Properly?

Jul 29, 2011

For some reason, it seems that the outer block doesn't seem to update recursively, as I expected it to. I want the loops to add all directories within "C:UsersDrise"to the array internaldirs(). Any advice on the correct way to do this, as it seems I'm doing it improperly?

Static internaldirs() As String
internaldirs.add("C:UsersDrise")
For Each internaldir As String In internaldirs

Game Programming :: Simple File Error

Aug 16, 2009

I am making a little game for my friend in Visual Basic 2008. It uses 3 files (gamedataidname.txt, gamedataidlevel.txt, gamedataidgold.txt).

When the play button is clicked, I wrote some code to check if the file exists and display the content of the 3 files. This part works fine. But then I have a 'Else' statement to create the files.[code]...

Simple Client-server Application Programming?

Nov 18, 2010

I'm trying to learn how to do some very simple client-server application programming.

Basically, I want to make a program (the server) that listens and waits, and when a commend is sent it will run a batch file or execute a line of code.

The client will just ask for the ip and send the command when a button is pushed.

Shouldn't be too hard right? So what are some good resources that you've used to get started?

a friend of mine wants to create a simple inventory database that can be deployed on the web.He has had a lot of experience with Database tools like Paradox. Moreover he has experience with writing Macros and programs with Basic, and even a bit of C++ experience. He uses Windows and Mac OS X, though mostly Windows.

If the requirement of having a web application wasn't there I would recommend MS Access.

Cancel A Task Which Is Not Performing Any Loop-based Statements?

Mar 27, 2012

I have an asynchronous task that is executing a function. The function does not contains any looping statements, but instead it is executing series of sql commands on sql server. Now, i have a button on my window that can cancel these sql operations. In other words, cancel the whole asynchronous task.

I know that this technique will require CancellationTokenSource and CancellationToken to cancel the task, but i've seen many examples on the internet and all of them are showing that the function that task is executing contains loop statements in which they are checking for IsCancellationRequested boolean property. But in my case, it is not so. My function does not have any loop statements in which i can do a check on this boolean property.

Simple For Loop On Fritz

May 21, 2009

I have an extremely simple for loop listed here and I've been getting incredibly whacky results. Right now I'm getting a System.OutOfMemory Exception. When it did run, I was getting results like this, "1, 100, 0, 200, 0, 200, 100, 1, 300, 100", where it continues for the whole loop. It doesn't matter if I do this or do a for each loop with an instance of what I'm counting, like a DataGridViewRow when I'm iterating through it's rows. I can't figure out what is wrong. I've went to a completely different computer with a completely different installation of Visual Studio (fresh install) and it still doesn't fix the problem. Now I'm getting that out of memory exception.It's a basic Windows forms app with two datagridview controls. A DataSet that has two tables loaded by table adapters. Data is from a SQL database, two different tables. I'm iterating through the rows in one datagridview control in order to update text in it with info referenced from the other datagridview control.

Game Programming :: Loop Causing Application To Freeze?

Mar 15, 2009

I'm having some wierd problems with my Looping. I'm was using a thread to start a looping routine to sample the keyboard for pressed keys. The loop worked fine when I made a call to it from the thread in my form load routine. However when I just made a call to the samplekeys routine without using the thread my application will freeze and it won't load.I'm making the call in the form load routine. Private KeyThread As NewThreading.Thread(AddressOf SampleKeys)hen start the thread in the form loading procedure , but if I just make a direct call to the samplekey routine without using a thread my application freezes.Here is the the thread don't think there is a problem with it.

Public Sub SampleKeys()
Dim N As Integer
N = System.Environment.TickCount

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 Explicit On
Option Strict On

I am hopeing someone can help me here with a recursive function I have that is not returning either true or false as I would have espected it to. The function loops through a Active Directory group for its members and then calls itself if it encounters any groups within the membership in order to gets its members as well. I am trying to return either true or false based on if any errors were encountered but not haveing any luck at all. It appears to just hang and never return back to the primary calling sub that starts the recursive function. Below is my code I am using:
