It really helps to have some other opinions! It might look simpeler to make two distinct events. But reading out the mm is really easy to do. So i didn't make more events for maximizing and minimizing. But further on i'm gonna use it. I think by now i have all the thing's i need to solute my problems.

I'm only using the maximize. But it seemed handy to do it this way and beeing abled to send over data from an other programm. That's what i want to use the mmap for. Or am i missing something. because i'm not really seeing what your point is. Because it is a complete different process what is calling the maximize (or minimize) i can't just create an event and call it (or can i?)

re:Open running processes
Well i want a external app to maximize and minimize my app. And later on i want the external one to send some data. Thought this would be the most easy (and fast) way! Greetz -- http://mail.python.org/mailman/listinfo/python-list
re:Open running processes
Well it doesnt work yet, but its gonna! ;) i've tested it with a little app. There is my main app (called it server) wich contains a thread. This thread listens to a mm (memory mapping) when an other program sets a flag (finished_producing_event.set() ) it just calls self.iconize(false) I'm not sure what pieces of code i have to post here.. posting all of it makes it too large i believe :) >From server: ID_MESSAGECH = wxNewId() def EVT_RESULT(win, func): win.Connect(-1, -1, ID_MESSAGECH, func) class ResultEvent(wxPyEvent): def __init__(self): wxPyEvent.__init__(self) self.SetEventType(ID_MESSAGECH) class listener(Thread): def __init__(self, frame): Thread.__init__(self) self.frame = frame self.setDaemon(1) self.stopped = False #shared_memory = mmap.mmap (0, common.SHARED_MEMORY_SIZE, common.SHARED_MEMORY_NAME) #ready_to_consume_event = events.Win32Event (common.READY_TO_CONSUME) #finished_producing_event = events.Win32Event (common.FINISHED_PRODUCING) def run(self): while not self.stopped: try: finished_producing_event.wait() wxPostEvent(self.frame,ResultEvent(None)) except Exception,e: print "Error: " , e def stop(self): self.stopped = True within the frame: [code:1:080343f1b1] listen = listener(self) listen.start() EVT_RESULT(self, self.OnChange) def OnChange(self, event): shared_memory.seek(0) tekstding = shared_memory.readline() if(tekstding.strip() == "maximize"): self.Iconize(False) self.Show(False) elif(tekstding.strip() == "minimize"): self.Iconize(True) self.Show(True) self.panel.tekst.SetValue(tekstding) [/code:1:080343f1b1] Hope you can see now how it works!

re:Open running processes
It is a wxWindow app. It is a kind of datamanager. it is possible to minimize it to the systray. hmm.. i've thought of an solution using memorymapping. see if it works.. don't know if it is the 'best' or 'safest' way.. but ok.

Open running processes
Hi all, I have a programm. In this program i've made the restriction that only one instance can run at the time. (done with mutex). Now i'd like it to open the running (make visible) instance when someone want's to open it a second time. Does anybody know how to do this? I hope you all understand what i mean. My English isn't to good... Greetz Rudi -- http://mail.python.org/mailman/listinfo/python-list
re:Single Application Instance Example
Whit this mutex is it possible when an instance is running in background and you try to open a new instance. you cancel it and show the first? Greetz -- http://mail.python.org/mailman/listinfo/python-list
