Associating a file extension to an application

[MJB]

I have an application that understands a proprietary format and file
extension. I can associate the file to my application using the windows
'Open With' dialog, but I want my application to automatically load the
file when opening it. What is the proper way to do this? An example of
how to pass the file to my application would be great.

Thanks,
Matt

Hi,

It goes in the registry , you can see this by creating an extension, assign
it to any program and checking the register after.

take a look at
http://msdn.microsoft.com/library/d...sics_extending/fileassociations/fileassoc.asp


A possible solution is to prepare a .reg file, put it as a embedded resource
and later just insert this info in the register.

The filename will be passed to the executable in a command line parameter:

\\\
Public Module Program
Public Function Main(ByVal Args() As String) As Integer
For Each Arg As String In Args
MsgBox(Arg)
Next Arg
Application.Run(...)
End Function
End Module
///

Select 'Sub Main' as startup object in the project properties.
