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?
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?

View 3 RepliesMy 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.

View 2 RepliesI 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)

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.

i need to find a control in a repeater in my asp.net application.At the moment I'm using FindControl("IdOfControl") and this is working well.
[Code]...
I am limited to using ASP .NET 1.1, as for this environment I cannot upgrade to 2.0 or beyond Essentially, I have a very simple datagrid that has a checkbox in one of the columns, which is a template column...the code for the datagrid is this:
<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
[code]....
Now, my issue is that when I set cbStaticRolling to the CheckBox control through FindControl on the e argument, it seems to set the variable okay, but doesn't seem to be setting the right one, or setting it properly, because "Checked" property is false regardless of whether I check the box or not?
I have a ListView called "orderReceiptTable" which I am able to properly access from the Code Behind. Within it is a literal called "orgName" which I obviously would like to populate with an organization's name. After much searching it was determined that FindControl was the right course of action. Perhaps I am using FindControl improperly but I am unable to actually have it "find" my Literal control. The code block is being called in the Page Load.
My code looks as such:
Dim orgNameString As String = getOrganizationName.getOrgName(organizationID).ToString()
Dim myOrgName As Literal = FindControl("orgName")
myOrgName = CType(orderReceiptTable.FindControl("orgName"), Literal)
If Not (myOrgName Is Nothing) Then
[Code] .....
I ran into a situation where FindControl was returning a control that wasn't a complete match of the Id I was searching by. There are two controls in the parentcontrol with similar Ids like: "MyControl" and "MyControlAlternate". When I call FindControl("MyControl") the control returned is "MyControlAlternate". I was wondering if anyone had any explaination why or thoughts as to what might be causing this problem. The way I got around this was implementing my own version of FindControl.

But none of these work for me.
I have a DataList inside a DataList that causes my page to lose the controls. The page works and there are no errors, but my label is never found! This is odd because the label shows on the aspx page, it just doesn't remove the 2 items that I want it to remove. When debugging, it skips over the If statement altogether:
If lbl IsNot Nothing Then
If lbl.Text = "Self Directed" Or lbl.Text = "Systems" Then
lbl.Visible = False
[Code]....
This will only hide the text for "Systems", I have gone through each label in that particular question and each has hidden itself. This code does work on another page so I know that Self Directed is exactly how it is capitalized. I even copied and pasted from the database and it still wouldn't hide.
I created a simple page with one button, then on the click event have it use FindControl, to get a reference to itself. But..... FindControl is returning nothing.

Dim control = FindControl("EntryDoor1")
control.Visible = False
End Sub

View 2 RepliesIve tried searching for hours now and cannot find out why my code (aka, me.) is failing
Basically... I have a listview control which I'm passing a datatable of products (ID, Name, Description and Price columns), and im trying to make it so that when the "checkout" button is pressed, it parses through all the controls on the page, finds all the controls with the correct ID's and adds the items values to the cart.
ive checked all my ID's in the source code and they match up to the ones being requested by the FindControl method.[code]...
How do you get a specific nested control of dynamically created controls (i.e. the child of a dynamic control)? The FindControl() method does not work because it only deals with TopLevel dynamic controls I believe.
View 2 RepliesI have a web page where I want users to enter ratings for a particular software. I have got this working fine. What I am after now, is that users need to be logged in to enter ratings. I have dragged the loginview control onto the page and dragged all the other controls/datasources into this view. However now I am getting alot of squiggly lines regarding my controls not being declared. I have been told that I need to use the FindControl method. However I'm not sure on how to use it in my instance as I have a dropdownlist involved.
The controls are called: LoginView1, DropDownList1, TextBox1 and Button1 for the insert.
Any proper declarations so I can insert data into my database. Here is the code as it stands outside of the loginview:
