VS 2008 For Each Loop (Step Through / Into)
Jul 5, 2009The following code is executed at an interval of 60000 milliseconds.
[Code]...
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.
Next Loop Only Works On Initial Step?
Oct 5, 2010My 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.

Using For Loop Step Keyword On Zero Based Arrays
Jun 12, 2011Attached 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:
CODE:
Any of the above loop setups works for me using VB6 Any Documentation or code would be use in my vb6 to vb2010 migration?

VS 2010 Parallel Loop Getting Bad Data?
Jan 25, 2011I've been trying to get this method to run parallel so it can take full advantage of all processors, and it seems like the data is running over itself. I didn't originally write it, so I'm having a hard time figuring out where it's running over itself when it runs parallel. It gets good data when it runs in a regular For loop.
Parallel.For(1, endm, Sub(m)
'Debug.Print("Top of loop: " & Now)

AxMediaPlayer Step Function Doesn't Step Backwards
Nov 10, 2011I 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?

Parallel.For Termination - Service That Scans Network Folders Using A Parallel.for Method
Jan 16, 2012I have a service that scans network folders using a parallel.for method. However recently I am finding if I stop the service then while windows says the service is stopped the process is still running in task manager. However it is at 0 cpu and the memory does not change. If I try and end the task (even a force in command prompt) it just says access denied and i have to reboot the server. What would be the best way to make sure everything terminates? I thought of adding a global Boolean that in the stop procedure it turns true and part of my parallel code will check for that and call s.stop.

Why VB Code Is Not Executed Step By Step By Using F11
Jun 13, 2011When 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.

Jun 8, 2011Now all went well about from using the structure correctly. The working of the structure was perfect. How ever i missed Two important issues. The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

Evaluates 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.

Different Results - Step-Through Vs Run
Feb 15, 2012I have created a program that randomly produces simple maths questions and saves them to a SQL Server (SQL Server 2008 R2). The code looks fine and works if I step through the program. Each pass it creates a random question answer and saves them to the database. However, if I run it (Debug/Release), the program produces a question and answer but repeats it in the database.
