  • Query events of an external DLL

    From =?UTF-8?Q?R=c3=bcdiger_Fresemann?=@21:1/5 to All on Tue Jan 18 08:15:08 2022
    I use an external DLL with some functions that I need.
    According to the manufacturer, the DLL also fires events, e.g. to query
    the status of individual processes.

    I just can't manage to get into this level. I have already tried with
    Dispatch, Events or ControlNotify, but get nowhere....

    Does anyone have any ideas or som examplecode on how I could best
    accomplish this?

    Does this DLL supplier not have example code, that works with their DLL? They should have C or some other code examples, to catch these queries. THAT is where you should start. Then migrate this code into a parallel thread in your VO. Read and write
    only to static variables, don't hit the stack, don't define new variables, don't call (non-static or iterative) user functions.
