I am running Microsoft Visual Studio 2008 Professional on a Windows 7 system. While working on the visual basic exercise in chapter 4 of the Microsoft Visual Basic 2008 Step by Step book on the MyMenu program I added a Toolstrip to my form and then I was trying to perform the add OpenFileDialog and ColorDialog controls to the component tray as described at the bottom of page 111 under Using Dialog Box Controls. I could never get the controls to appear in the component tray as instructed in the book.

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?

My need is to work with what I have (2005 studio), what I know (Visual Basic) but need a primer. I am a visual learner (so I need to see [1] how the form is created, named and set up). From there I need to see [2] how he code works so that I can implement from there.

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'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

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.

Is this the correct forum for questions regarding code in the Visual Basic 2008 Step By Step? If so I would like to know why there is a declaration for one PictureBox and not the other. If there is a better forum for Michael Halvorson's book, can anyone direct me there?

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.

The 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.

I have VS 2008 on two computers. I seem to recall F8 as being the keystroke for Step Into on both computes, but somewhere along the way this changed for computer #2, and it is now F11. I've looked through the settings and I can't find where this may have been changed.
Another change that has taken place on computer #2 is that exceptions are no longer caught and displayed. If an exception occurs, the code keeps running or just returns to the project--no information is presented at all. Meanwhile on computer #1, everything is as it was before, an exception is caught and an information window is presented showing some brief information along with one or more links meant to help with resolving the matter. What has happened to the environment of computer #2? I don't remember changing anything, but clearly something did change.

I have been making an online role playing-game in VB2008 and inside the gameloop for the client there is some code that "smoothes" out the movement (instead of it being choppy from tile to tile.) It works pretty well but I'm having problems figuring out a math formula to get a good frame timer interval to set how fast the frames change based on how many pixels they can move per loop.Testing stuff out I found that 250ms is an ideal frame timer interval for 1.0 pixel movement per loop. If I were to double the movement step of pixels by 2 lets say (2.0 pixel step per loop) I found that the frame timer interval should be around 125ms. How can I get the frame timer interval by the movement step of pixels? In cases where the movement step can anything between 0.1 to 4.0 pixels.

I 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.

If you try and do the same in a control that inherits Control, you get an error,Keyword is not valid as an identifier. Since Step is a keyword via the For Next statement.
So, how do you achieve the same as the ProgressBar has done in a custom control?

I want to create a function for use on my ASP.NET 3.5 website that will step through a folder of image files one by one. Each filename found would be checked to see if it met certain conditions (this would involve making checks with the associated SQL Server database). If the file is okay, the function would just move on to the next file. If not, the file would be moved to another folder.I don't know how to define the list of files in a folder.

I am using VS2010 Pro and can no longer see the step into command buttons on the toolbar. That and the step out have disappeared. I know I had many more toolbar buttons across the top that I don't see now but the debug toolbar is checked but there isn't even the step into or step out options to add to the toolbar.

I have recently updated my VS2010 Professional IDE to SP1.
Now the F8 key no longer provides single step functionality (nor does F11). Likewise the F5 key no longer runs the debugger. I can access these actions via mouse using the run and single step icons on the toolbar.
These very important functions have not been restored using any of the Tools|Options settings that I have been able to find.
I have attempted to "repair" the SP1 installation without success...with a number of errors being reported starting with an RiaServices.msi error.

I'm trying to build a four step process into a VB.NET GUI. The application transfers objects from AppA to AppB.
The application will follow these steps:
User constructs a general query in the GUI to identify which AppA objects to transfer. Model gets queryResults, datagrid in View lists each result User deselects items not to be transferred to AppB Model transfers selected items
how this should work. I've have the following functions implemented in the model, but don't know the MVC-way to tie them into my GUI:
Function getQueryResults(queryParams) as Items
Function transferItems(items)
Do I keep the Items data structure in the model?
How do I remove deselected from the Items data structure without building logic into the view?
Both of the above functions take time, how can I design thing to allow me to BackgroundWorker the model's functions?
