Example code gives exception on win7

Post by AndersJ » Thu Jan 18, 2018 11:08 am

Hello everybody !
Tried to make the callback example (http://developer.telldus.se/browser/exa ... #callbacks) work on win7 on a 64 bit machine.

The VS 2008 project is uploaded here: https://docs.google.com/open?id=0B92w5F ... VJiMGxvS0U

It almost works, when sensor is activated, callback fires but but crashes occurs when returning from Events::deviceEventCallback:

First-chance exception at 0x00000001 in telldus.exe: 0xC0000005: Access violation.
Unhandled exception at 0x77e815de in telldus.exe: 0xC0000005: Access violation.

Anybody has a clue on this ?

Access violation 0x5 is usually a null pointer problem.

I have a working implementation for both 32 and 64bit which I use in BM. Although it is targeted towards Mangaged .NET, the interface to Telldus' API uses C++.
The library is licensed under LGPL, see the download at the bottom of the page at http://www.beyondmeasure.se/download/

Or you can use BM and benefit from all the rest of it's functionality :)
