Reusing the same application Instance

[davidbeechum]

I have an app that sits down in the system tray. perodically doing things. users can click the icon in the tray and add files to send out. what i want to do is have a Windows Context Menu OR a Send To shortcut so a user can click on a file and "send it" to my RUNNING application. I know how to make a "send to" shortcut for a normal application, but i dont want to run more than one instance of the application and the application will start when the user logs in. I guess Windows Media Player is a good example of the functionallity i am trying to achieve. If WMP is already running when i double click a new media file, WMP just starts playing the file. i dont really need the file contents, just the file path. I have been trying to find a good DDE example, and im not even sure this is the correct/best way to do this. Im using vb6 as my dev enviroment. and im not using any .Net code for this project if i can help it. any ideas/ code examples would be appreciated.

Just an idea - probably more of a temporary workaround than a permanent solution, though.

You could set up your SendTo shortcut as usual, and in your app try something like

If App.PrevInstance Then
  Somehow pass the data to the executing instance
  End
End If
