[URL]
Now that is for visual studio 2005 but I figured it would be a good enough place to start. So I tried using the add in wizard and createing a new add in...
The funny part is they say that the wizard creates a basic add in that works. But straight out of the wizard attempting to test it I get this error:
"The Add-in 'Project1' failed to load or caused an exception..." blah blah
"Error Message: The system cannot find the file specified.Error number: 80070002"
I just think it's funny that the basic VS created add in from the wizard dosn't work right. So can anyone help me on how to get started and properlly create / load an add in?
I have previously created a DLL in VB6 that I then used in a Microstation VBA program. But now cannot create a DLL with VB 2008 Express that works. I am trying to create a simple test DLL. The DLL appears in the Release directory of both the Bin and Obj directories but when trying to register it I get the following message "Can't find DLL entry point in TestRun.dll". Is it possible to create a working DLL with VB Express or do I have to "upgrade" to another "version" of VB.

How do you create your own custom component for vb.net 2008? I want it to simply output to a .dll, not a whole winforms app.
How can I control the component? For example, I want my component to not have a visible design view, I want it to stay below like the stopwatch component and the notifyicon component and such, it is not something to be designed. Then, how do I edit the possible properties a user can control, and make them effect the end result?

View 2 RepliesI need to 'download' the contents of an XML file that resides on some web address and parse them. I need to do this about once every 5 seconds. I use a HttpWebRequest to do it, but I don't think that's relevant.The 'problem' is that this request + parsing can take a little bit of time, and even more time if internet is a little bit slow. So, I decided to do it in a background thread.I have a method, let's call it GetXmlInfo(), which does all the hard work. Then, I have a timer that ticks every 5 seconds. Now I have two options for starting the thread.Option 1: creating a new Thread object every time the timer ticks:
vb.net
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles Timer1.Tick Dim t As New Thread(AddressOf GetXmlInfo) t.Start()End Sub
[code].....
In option 2, when the GetXmlInfo method has not finished yet, no new thread will be created and the GetXmlInfo is 'skipped' for one timer tick (or possibly more). Could this create a sort of "deadlock" (I know it's not really a deadlock), like if the thread never finishes for some reason?
