How to know if paylink's interface is enabled?

Post by dotnetguy »

Here is my code

Code: Select all

static void Main(string[] args)
{
    var open = AESImhei.OpenMHE();
    if (open != 0)
    {
        throw new IOException($"OpenMHE returned {open}.");
    }

    AESImhei.EnableInterface();

    var initialValue = AESImhei.CurrentValue();
    var latestValue = initialValue;

    while(latestValue == initialValue)
    {
        latestValue = AESImhei.CurrentValue();
    }

    Console.WriteLine(latestValue - initialValue);

    AESImhei.DisableInterface();
}
When I run your Demo.exe I can use attached hardware (insert money, dispense money, etc.). Demo.exe hasn't failed so far,but code snippet above has.

It seems that sometimes AESImhei.EnableInterface() does not succeed. Here's how I can reproduce (altough not always, but enough to consider these steps viable):
1) Hardware is setup, Standard.cfg is correct, paylink.exe is running.
2) Run Main(). Money is accepted and amount is printed out to console. Program exits.
3) Run Demo.exe. Everything seems to work. Close that program after some seconds.
4) Run Main(). Paylink won't accept any money, but CurrentValue can be read. Terminate program, because CurrentValue is not going to be updated.
5) Run Main() again. Everything seems to work.

Is this expected behaviour?

In this situation I'd like to have way to validate if interface is enabled. Is it possible?

Hi,

The key line in your diagnostics is:
10:27:02.932 DP: Application Watchdog triggered
This application watchdog is controlled by CheckOperation() which is used by the Demo program - and which is only checked while Paylink is running, i.e. the DLL is loaded and EnableInterface() has been called.

Checking the Demo program code, is appears that the application watchdog is only turned off by pressing the Exit button, not by closing the program with Alt-F4 or the X.

It appears that the acceptors were actively disabled after your program enabled everything because the watchdog that had been being run by Demo expired.

If you re-run your tests and use the Exit button, I expect that you will not see any problem.

Indeed. Using "Exit button" vs closing window or alt+F4 made a difference.
It's something to keep in mind when using CheckOperation(). Thanks.
