My For... Next Loop will not work and I cannot for the life of me figure out why. I have tried to display the results in a label and a text box with multiline enabled. Doesn't seem to matter. It's probably something obvious I have been overlooking for 2 hours.

I'm trying to understand how this code work step by step but I'm confusing How the code work when executed from first step to last step?example: when I set obj to age = 39 . is the first step is checked if the variable in m_Age or checked in Property Age
vb
Dim obj As New Minimal obj.Age = 39 MsgBox("after setting the age to 39, age is " & obj.Age.ToString)
vb
Public Class MinimalPrivate m_Age As Integer Property Age() As Integer Get Age = m_Age End Get

im running this bit of code that only works in step over. i tried running it normally but it didn't work then when i stepped over the code it works fine has anyone ever come across anything like this??

I tried doing a step through starting at a break point i put at the For Each line. It will go inside the For Each loop but when it reaches the first if statement and it finds that if statement false it will not go to 'Next' and continue to execute the loop instead it goes to End Sub. I want to be able to view what is going on inside the loop, i think the final upload process works so it does do the loop, though i can't step through to view it.
if there's any overload that would allow me to specify a step size in a Parallel.For loop?
View 1 RepliesAttached is a visual representation of My Array that was used in my VB6 program the dimensions are:
CODE:
I am using an ACCESS DataBase to populate the array.
Using the For Next Loop I can access any position within the array such as a individual cell or group of cells. Also using the Step Keyword of the For next loop I can select a group of cells to manipulate based on the Step factor. This worked well for me in VB 6. I am now migrating to vb 2010 and cannot fine documentation as to how this would be done on zero based arrays in Vb 2010.
In VB 2010 I see no reference to the Step Keyword nor examples of how it would be used with zero based Arrays.
A example of my use of the step keyword is:

Any of the above loop setups works for me using VB6 Any Documentation or code would be use in my vb6 to vb2010 migration?

I have a program that plays a video and uses the step function to move frame by frame backwards and forwards through the video. The forward frame works just fine:
AxWindowsMediaPlayer1.Ctlcontrols.step(1)
However, the backwards step (below) jumps a full second backwards while the forwards step only steps .033 seconds forward (presumably a single frame).
AxWindowsMediaPlayer1.Ctlcontrols.step(-1)
I can't find any documentation about this problem online and in fact I can't find much mention of this function.the documentation does say the -1 command should step back one frame. IWMPControls2::step method Is this a known bug or is there an updated function I should be using?
I really need to learn much about it, but always stock up,.DOTNET covers the vb.net, C#, C++, ASP.NET, .NET framework is it right?.C++? ASP.NET?What should be my step by step procedure?
Will I start on database? Connection of client and server? Webrowser? Application?...etc etc etc.Will it ok if i start on studying every toolbox item one by one?
I dont have any project or every assignment that needs to be done....All i want is to learn about DOTNET
coming to the topic i want to learn dotnet i am not good at programming. but i want learn it i m very passionate about it.you all know soo much about DOTNET even i want to become like you people.i have a bit knowledge about this but not much..What should be my first step towards this?How should i start with and from where should i start with?

I 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

I have used the cards procedure in other programs and it worked fine.
I�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.
I have a wizard where users need to fill out data. You cannot navigate to the second step until first step is completed.
I enforced this behavior by disabling/enabling "Next" button, but I really do not like this solution, since it seems not really elegant or safe here. What is the good approach on building step-by-step processes with enforcing step completion.
I seem to lost the practice files disk for this book, and I am trying to 're-learn' this book. I am unable to do the lessons without the practice files. If you have the disk and could maybe zip them up and email them to me? I have the other disks still, and am using the Visual Studio Express to do this.

When I started to work on this new project in vb.net 2010, I put many breakpoints to try to understand the execution order of the project, only to find it in vain. Step into command F11 should work correctly according to Visual Studio 2010: Step Into Property/Function(F11) doesn't work as expected. But I when I pressed F11, I found the code is jumping from one place to another based on breakpoints, not line by line or step by step.To give an example, please see the code below
Me.tcData.Alignment = TabStrip.TabControl.TabAlignment.Bottom 'line 1-breakpoint
Me.tcData.Dock = System.Windows.Forms.DockStyle.Fill 'line 2
...
Me.tcData.TabsDirection = TabStrip.TabControl.FlowDirection.LeftToRight 'line 3
[code]....
When I press F11 at line 1, it goes to the property 1. After it returns, when I press F11,it goes to property 3 directly, without accessing the code in line 2 and line 3.I do not understand why the code is NOT executed step by step by using F11. If I put breakpoingts in line 2, then line 2 is executed.So it seems to me that the showed execution order is based on breakpoints! So if I put breakpoints at different places, the showed execution order would be different! Thus, it is impossible for me to really understand the execution order.

My 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
