That's what I'm planning on making, for the unfortunate people like me who don't have DirectX8-compatible videocards. So, I'll put a poll similar to chris128's. First of all, is this is even possible in VB.NET without a truly ridiculous amount of code? What would be the performance cost? Is there a formula I can use to incorporate the Z coordinate and the viewing angle to X,Y coordinates? I've got a lot of it done already, and this is a rather key component I'm missing
There are all kinds of renderer's in .net for rendering system control image components (like the TrackBarRenderer for eg. but where is one for the listview header?.. I want to know how to draw one!
I have tried last time to do this. but i face lots of hurdles now i want to start from scratch. i want to develop a web browser using gecko skybound rendering engine.
In VB.NET Tutorials I was following the tutorial Customize your toolbars and menus with a custom renderer and with the folowing code I get an error 'Declaration expected'
But I get a TypeLoadException when loading the configuration file, and log4net internal debugging gives this detail:
log4net:ERROR OptionConverter: Could not instantiate class [LogLibrary.Log4NetObjRenderers.PdaLogObjRenderer]. System.TypeLoadException: Could not load type
I'm calling the following method from a button click event to export a datatable to excel. After the export is completed, the excel application object is quit, released and assigned to nothing. But in reality it's not getting released and stays active unless the entire application is closed. So every time the button is clicked for export, a new excel application object keeps on running. The problem doesn't occur if two of the lines from the method below are not used. But I can't omit them as they are really needed. Check the * marked lines.
Code: ''' <summary> ''' Exports data from a datatable to excel. ''' </summary>
How to change the frame rate in Visual Basic 2008 Media Player? I have error: System.NullReferenceException was unhandled Message: Object reference not set to an instance of an object. IS there any way to fix this? Here's My Code
i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.
this event works ok, but the problem is that I don't know what field was clicked. Should I use objectinfo or something else? VB.net won't recognize for example e.objectinfo.

I use the 'Process' object to run EXE from my application. It works fine when it run on Windows XP and 2003. When it run on Windows server 2008, it hangs up: the process is stayed in background but never returns. It never goes ahead for the next commands. What could be the reason? [Code]

Is there a way to validate a groupbox with a couple radiobuttons in it to make sure that one of the radiobuttons is selected?
Heres why I need this. I need a user to be able to select their class rank out by way of radiobuttons in a groupbox. When they click submit, I need to validate that atleast one of the radiobuttons got selected and if not display a messagebox.
I got one reply early of:
If myGroupBox.Controls.OfType(Of RadioButton).Count(Function(rb) rb.Checked) = 0 Then 'There is no RadioButton checked in myGroupBox. End If
Is there any other ways other then that? Preferrably a more 'dumbed' down way? This is for just an entry level VB class, I would prefer not to use something of that nature if there is another way.
I am running a program that is connected through the internet and i gets disconnected at times.wanted to know how this would be to examine a color of a pixel , If the colour turns changes, my mouse will move to reconnect
I get the message "Please wait while Windows configures Microsoft Visual Studio 2008..." whenever I build the install project for my application. It configures VS for a while, then builds the project. This does not happen when I build the vb.net application itself, only the installation project in the same solution. This occurs on applications using the Leadtools library, but not others.
I have been working on an app that was basically a vb6 app but had to be changed and I did it all using VB 2008. works well, great. One of the problems that I had was to work on different groupboxes or frames. Since they are layered on top of each other, working on one frame would mess up the others. Eventually it all went okay. but now if i want to add another item in the menu and hence add another groupbox (or frame) in the same app - it would definitely be a nightmare.
I recently created a very simple project in VB express 2008 to interface with a COM object from an external vendor. I then downloaded the VS2008 90 day trial and found that the identical code in a VS2008 project results in a COMException error "Object is out of scope". Is anyone aware of any differences in how the two packages handle COM object interfaces as I have run out of ideas. Both projects have identical code and all the references are the same. The CreateObject() method correctly creates the object, but any attempt to access methods inside the COM object result in that error. I can even open the VB 2008 Express project inside VS and it still generates the same error.
Here is the code - the vendor dll in question is from Siebel v8.0.0, you'll notice that I have commented out most of the code that comes after the error. Creating a watch in the debugger on the siebApp variable sees it correctly created as {System.__ComObject}type SiebelHTMLApplication. I first tried this by creating the Property Service for variable siebSvcs, but after I started experiencing the COMExceptions, I reverted to using the most basic method inside the COM object I was creating.
