Main Host application memory error #22

Closed taylorlm88 closed 2 years ago

taylorlm88 commented 3 years ago

If you try to send a command to the Main Host application via its Labview GUI before it has been connected with the command connectHost, it starts sending a slew of "out of memory" errors. This error window pops up over and over again, you might get a dozen or more before you manage to close the application. It'd be nice to have a better way of handling this if a user forgets to run the 'connectHost' command, like a single error message reminding them.

To replicate this error, start G4 Host.exe, then issue the command Set Pattern ID = 1. This leads to a quick increase of memory usage and the application crashes with an out of memory error within a few seconds.

The pattern can either be set via the GUI (see below) or via the TCP command [0x03 0x03 0x01 0x00].

Sending a Set Pattern and Position Function with any number (eg [1 1]) also creates a similar memory issue.

This is what G4 Host.exe reports:
