Using DDE with Visual basic

I'm not 100% sure if DDE is the method, but I'd like to pass file information to my small text editor app so that when you double click on a text file, it launches the app and opens the file. Thus far I have been able to make my app the deafult text editing progam, but failed tring to get the file opening functionality to work?

Anyone have any suggestions or know of an API to use to accomplish this?

If you have got windows to launch your app when double clicking on the file, all you have to do is open the file passed to your app in the commandline. Something like this:

Code:

---

ption Explicit

Private Sub Form_Load()
Dim hFile As Integer
Dim Text As String
    If Len(Command) > 0 Then
        If Dir(Command) <> "" Then
            hFile = FreeFile
            Open Command For Input As #hFile
            Text = Input(LOF(hFile), #hFile)
            Close #hFile
            Text1.Text = Text
        End If
    End If
End Sub

---

Thanks a lot. I'll give it a try.
