Vizard Matlab interface - no data printing

[shall6]

Thanks for the assist - can't believe I missed that. Now I'm on to the hard part (been hunting through old threads but no answer).

When I run with the if statement, I can't get it to work. It has to do with the data coming through as e.raw_data. I tried converting it to a string but I still can't compare it. This is what I have after trying to convert BOTH my data and my if object (already a string) to strings. It still doesn't work. Of course it will recognize them as NOT equal... but that doesn't help me much. Why can't I actually turn this raw data into an object?

dataNetwork = viz.addNetwork('OEM-PC')
def onNetwork(e):
    if isinstance(e,viz.RawNetworkEvent):
        print e.raw_data
        v = str(e.raw_data)
        if v == str('hi'):
            print v

viz.callback(viz.NETWORK_EVENT,onNetwork)

Thanks!

Try using the following code to see what the contents of the raw_data attribute is:

def onNetwork(e):
    if isinstance(e,viz.RawNetworkEvent):
        print repr(e.raw_data)

Keep in mind that the raw data can contain trailing NULL (\x00) byte values, so you might need to account for this if you are expecting to receive a string.

That's exactly it

I got 'hi\n'

Any chance there's a simple way to remove the trailing parts?

You can use the following to strip trailing newline, space, and null byte characters:

v = e.raw_data.rstrip('\n\0 ')
