VB Setup Projects File Associations + more
Hello,
I have recently acquired the Visual Basic .NET 2003 software (to begin programming, I went through the Visual Basic .NET Step by Step book), and have some questions about VB .NET programming that I could not find answers to in the help files. If anyone can answer these questions, some samples in code would be very helpful too. The questions are:
1. VB Setup Projects File Associations: I have been trying to create file associations (using a setup project) so that when a file is opened via Windows Explorer (say a text file: file1.txt) it will start with my program and the program will show the file chosen. The trouble I am having is that I can't find out how to make the program recognise and open the file selected in Explorer. The only thing that happens when I double click a file is that my program starts, but without showing the file. I think this is something to do with Actions, but where do I put the code, and how do I make it open the file selected? Basically, what do I do?
Here are the other questions:
2. Port communication: Is there any way to communicate directly with ports (i.e.. the sockets at the back of the computer) that is not too complicated (like I think writing driver software would be)? I am thinking of making an electronic device to be controlled by the computer, so no current software would recognise it.
3. .NET Compact framework: Would the .NET compact framework be suitable for desktop computers where installation size is important? If so, how do I obtain it (for redistribution)?
If this is not descriptive enough, please tell me what else you need to know. I have tried many people, but nobody has been able to help.
Thank you for your assistance.

You can create a Setup and Deployment Project to create a file association:

Regarding port communication see the following:

The Compact Framework is for .NET applications that run on mobile devices.

I have got File associations working with Console Applications, but when I try using Command() in the Windows Forms enviroment I get the following error message:
'System.Windows.Forms.Command' is not available in this context because it is 'Private'.
'This is the code I typed above the 'Windows Forms Designer Generated Code' Region
'of Form1 (the startup form)
Dim filename As String = Command()
Do you know how to get Command() (or it's equivelant) to work with Windows forms? :confused:
# 4 Re: VB Setup Projects File Associations + more
Command() is a function, so it must be used within a method (a Sub or a Function). It sounds like you're trying to use it outside a method.
Another option is to start your application with a Sub Main, which may optionally receive command line parameters as an array:
Sub Main(ByVal args() as String)
For Each FileName As String In args
' Process FileName here
Next
End Sub
# 5 Re: VB Setup Projects File Associations + more
When I enter that code and choose 'Run', I get the following build error:
No accessable 'Main' method with appropriate signature was found.
I tried making a Main() function (below), but it still had the same error!
Public Sub Main()
End Sub
:confused:
