Hi, thanks for Launch4J. I used it since 3.0.1. It is a great tool.
Recently, I need to make my app
- Only single instance
- Pop up a message, if user try to launch the same app for 2nd time
I make the following modification.
Single instance feature works. But the custom message doesn't work. No message
shown, when the same app is launched for 2nd time.
When launching for 2nd time, Launch4J will make the app window activate. However,
this creates problem when my app window is invisible and become a tray icon.
When I launch the same app for 2nd time, I will get a blank white window being
Any help is appreciated.
Here's how the settings look like in GUI
