How to use the Watchdog with VB.net and CE7?

According to
http://developer.toradex.com/knowledge-base/watchdog

I tried the SW Watchdog with “WatchDogLib.dll”.

I’m using Apalis T30 with Win CE7 (V1.4). WatchDogLib has Version 1.0.0.

WatchdogGetLibVersion (DWORD *pVerMaj, DWORD *pVerMin, DWORD *pBuild) ==> Returns True and 1,0,0

WatchdogInit (void) ==> Returns True

WatchdogRetrigger (5000) ==> Returns False

WatchdogDeinit (void) ==> can't PINVOKE

At least the CPU doesn’t reboot after 5s. I didn’t test yet if it reboots after the Default TimeOut.
For CreateWatchDogTimer (Windows CE 5.0) | Microsoft Docs i have no exact Idea how i could use it.

The watchdog lib is currently only supporting PXAxxx modules. For Tegra modules we recommend to use the hardware watchdog as well as WinC Software Watchdog.

I assume you could use the Software Watchdog the same way you Pinvoke our libraries. See also some more details on our developer website about this topic.
