One instance and params

[AndrzejB]

How allow one instance and:

• if is running, second call activate it
• params second runnig should be provided (by message?)

I have written editor in Delphi a lot of time ago, and I use:

• memory mapping with unique key
• params by messages
  But it works only under Windows.

Hi,

QtSingleApplication comes to mind for that.

console.exe is ok, but loader.exe and trivial.exe shows window only from Qt Creator IDE, else nothing (I provide dll's)
