View 3 RepliesI have a program I am trying to create in Visual Studio 2010 Ultimate, and have a few questions as to whether what I would like the program to do is even possible - Here is the idea of my program:
I have a main form with a ComboBox1, Pic1, ImageList1, and Label1 - In my ComboBox I have 118 entries, and 118 corresponding Images in the ImageList control - Right now I have it set to show the Image from the ImageList when a ComboBox1 entry is clicked, by the Index number:
If ComboBox1.SelectedIndex <> -1 Then
Pic1.Image = ImageList1.Images(ComboBox1.SelectedIndex)
Else
Pic1.Image = Nothing
End If
What I want to know is, Can I make it so I can add/update entries in the ComboBox1 and ImageList1 at runtime? Such as, have an 'Open' dialog to import the Image I want to add, and a simple InputBox to add to the Combo1 list? Also, if this IS possible, if I add Items at runtime, won't it mess up my Indexes, and then the correct Images from the ImageList1 won't be the ones that show?
I know, lot of questions, but I am trying to cleanse my mind of VB6, and focus on .NET - More complicated, but I like the appearance of the finished programs much better, without stupid additional OCX's
Apparently Crystal Reports doesn't come with VS 2010 Ultimate like I thought it did. When I went to create a new report, I got prompted to download it free and install it. Then, after installing it, I tried to recreate a report and got the same prompt to download it again.

View 3 RepliesI have been using the VB IDE for many months on a VB6 translation to vb.net 2010. I have had no troubles building and running in debug,until the message below just appeared. This now prevents me from running in debug. I have not used Publish in the Build menu or used ClickOnce. The Project - application page has "enable XP visual styles" checked. I do not want this unchecked, which will remove the error message below.
The error message is:

Installed DirectX11 June 10 SDK on Win7 machine with VS2010 Ultimate. Project written in Visual Basic, targeting .net 2.0. Just need the directx audio player capability.
Tried to add reference to the SDK Developer Runtime Files.
Nothing from DirectX11 shows up in the add reference COM for the project.
I can't seem to make my project see or accept the DirectX11 .dll's.
Unclear of which one I need other than maybe XAudio2 (I think) to play a .wav file.
DirectX11 SDK Release Notes say's the following but I don't understand it.

OK, So I am making a program in Visual Studio 2010 Ultimate. I have gotten all the forms and everything correct. Except the text color. I need to make it so when they reach the end and it says if they got it right or not, that the program changes the textbox's text color. The code I currently have is when form2 = the first word in the spelling test. Form2.textbox1 is the first place where the user puts the answer. Form1.Textbox1 is where the user puts the original word.
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If Form1.TextBox1.Text = Form2.TextBox1.Text Then
TextBox1.ForeColor = Color.Green
Else

This code does nothing and there is no errors. P.S. If you need a copy of the program, you can download the solution here: [URL]...
I am a visual basic developer and I use Microsoft Visual Studio 2010 Ultimate Edition. I've been making applications that can play only in my PC because it requires .NET Framework 4, which is not installed at even Windows 7 nor Windows Vista nor Xp. So, I decided to use Visual Studio 2008 which uses .NET Framework 3.5 SPI. It still doesn't run in common PCs. I believe it is pointless building applications that can perform only on programers' PCs. Is there any way to avoid using 4 or including it for the installation. I also downloaded .Net Framework 4.0 from this location [URL].. on a XP computer and my app couldn't perform because it was 3.5 SPI.

View 3 RepliesI am finally switching from VB6 to VB Net and am rewriting a technical application that calculates the heat transfer performance of automotive radiators, heater cores, evaporators, condensers, etc.The user can calculate a heat exchanger and save the results to an Excel spreadsheet. After a series of calculations he can then plot curves of performance.
He can also click on a previous calculation in Excel and import it into the VB routine. The user may have a number of workbooks open when he does this.My problem is I need to open the Excel workbook that is the active workbook. I have been able to select the active worksheet but have been forced to specify the index of the workbook. I have not been able to get the workbook I want.. The code I used is the following,
Dim oExcel As Object = GetObject(, "Excel.Application")
Dim oBook As Object = oExcel.Workbooks(1)
Dim oSheet As Object = oBook.activesheet
How do I get the active workbook instead of Workbooks(1) with an index of 1?

View 13 RepliesI am not a CS major. I'm taking Mechatronics.But I'm always leaning heavily towards embedded programming and electronics. Nowadays, I would want to take the dive into PC programming. Slowly.So, I've started to learn VB.net. The syntax and basic programming principles are still ok. But I got stumped when I tried to go deeper where I see, directx, directshow, dll, avicap32, and etc. What are they? and API? How ar they connected with VB.net? It's different when I'm programming microC, where the environment is limited and dictated. Now there are options so broad until I am lost.is the architecture and what has those APIs , DLLS, and etc mean literally.Ultimate goal would be using VB.net to interface with webcam and do image processing.

View 3 RepliesI am building a sort of 'lightweight' Visual Studio, and I'm trying to implement the feature where you can drag tabs to different 'tab groups', viewing multiple tabs side by side.
I got nearly everything working, I show a ContextMenuStrip when you rightclick the tab headers, with the option of creating a new (horizontal or vertical) Tab Group. When that happens, a new TabControl is added dynamically and the selected tab is moved there. You can drag the tabs around inside a TabControl and even from one to another.
The problem now is keeping track of the 'active' tab. Since I have multiple TabControls (not just two, there can be as many as you want theoretically), their SelectedTab properties are basically useless. How am I to determine which TabControl the user is currently working in? Obviously I will always have multiple selected tabs, but only one active tab, in which the user is currently typing, editing, whatever.I need to know the active tab for obvious reasons: many menu and toolbar items act on the active tab for example. A short explanation of my controls:I have one TabGroupContainer control, which inherits UserControl. I have a TabGroup control, which inherits TabControl.I have a Tab control, which inherits TabPage.
The TabGroupContainer holds a collection of TabGroups (to which I dynamically add/remove TabGroups when required). Now I want the TabGroupContainer control to have the ActiveTab property which returns the one and only active tab (out of possibly many selected tabs).The only logical way is to keep track of the tab that was selected last, for every TabGroup.
At the moment, I am doing this:
- In the TabGroup (TabControl) class, I shadow the SelectedTab property (and return a Tab instead of a TabPage). More importantly, in the property setter, I raise a SelectedTabChanged event:
vb.net
Public Shadows Property SelectedTab As Tab
Get
Return DirectCast(MyBase.SelectedTab, Tab)
[code]....
However, it still doesn't work. I soon figured out why: I am checking that the previously SelectedTab is not the same as the new value in the property setter of the (shadowed) SelectedTab property. I don't raise the event when they were the same, and in this case they were the same (as there is only one tab in the TabGroup!).So, I took that check out, and now it seems to work when I click in the text editor.
So one problem remains: the active tab is not changed when you click on the tab header (and not on the text editor). I am clueless as to how I should handle this... I am once again sure there is a simple fix, but I cannot see it. I can click the tab header, and I'm sure behind the hood it responds to this click, but it never raises it SelectedIndexChanged event because the index didn't change but was set to the same value it already had. I cannot override the SelectedIndex property (so I could skip this check and raise the event anyway even if the value didn't change), and the OnSelectedIndexChanged method is not called, so I cannot use that either...
I've been whining for several months about the way Windows 7 prevents application exceptions from actually occurring, and arbitrarily assigns "compatibility settings" without actually detailing what those settings are, even during Visual Studio Debugging operations. Am I just completely ignorant to some setting I can toggle to turn all that garbage off and make Win7 act like an operating system that wasn't designed for a 2 year old? It never hurts to try. In a worst case scenario,
