Spsser's
Happy new year! Here's the deal. I'm trying to get a wxpython gauge to signal the beginning and ending of spss commands. Currently, I'm using the thread command to run my spss commands while a gauge is running. The main problem I'm having, and I recognize that this may be a symptom of larger more basic pythonic problems (due to my inexperience), is that I cannot get the gauge to sync with my spss process. I want it to start when an spss process starts and end when it ends. Perhaps the thread command is not appropriate here? I have written this program to create a list of doctors from medical claims data to be used in another module where I have set up check boxes that trigger an analysis to be run for whatever doctor's box is checked. The program is running with the SPSS Python-Integration Package, and is running externally, not in SPSS. I just needed some indicator that the process was running because it can take a long time (15, 20, or 30 minutes, depending on the size of the claims file which can be more than 4gb). Okay, here's the syntax. Please excuse any sloppiness in my form. I'm just learning.

You are using the thread module. The threading module is higher level and might be easier to use. However, with thread, the way to make this work is to first allocate a lock (thread.allocate_lock). Have the thread running syntax acquire the lock and release it when it is done. Meantime, your progress dialog would try to acquire the lock with a timeout of a second or so. If it fails to acquire the lock (acquire returns False), poke your progress message (or let it keep running). Once it succeeds in acquiring the lock, tear down the progress message and delete the lock. You could keep this lock around and reuse this protocol if you have multiple instances where you need to wait. If you used the threading module, you might do this by having the syntax thread exit when it is done and using threading.join with a timeout to wait for it. HTH, Jon Peck SPSS, an IBM Company [hidden email] 312-651-3435 Caveat: I haven't used this type of threading to run SPSS syntax. It would not work with V15 or earlier and maybe not with V16, but it probably works with later versions.
