Well, SetTimer mostly works. If I'm not really careful it brings down Messenger Plus and concequently MSN Messenger. Of course, now I can't get actions to properly fire using the IMessenger interface. Man I hate Visual Basic.

You hate VB? Well, great, I code in C++

You have to use QueryInterface to get IMessenger and set it to a global variable (so that your call back function can use it) in Initialize function, like

IMessenger* MsgrInstance;

iMessengerObj->QueryInterface(IID_IMessenger,(void**)&MsgrInstance);

Well, this plug-in is to support a fairly large behind schedule VC++ app. I'm using VB to get things done faster. Of course, I'm still having the problem where a video invite won't fire If anyone is curious, http://www.msnfanatic.com/forums/index.php?showtopic=9888&st=0&

Mnjul, you don't have to QueryInterface, a mere typecast to IMessenger3* will do the trick (not pretty though I admit).

CMI, if you want to fire off a new thread in C++, just use the following function call:

code:

---

_beginthread(<funcname>, <stacksize>, <arglist>);

---

I've only used it with a function that takes a single argument, so I'm not sure how it would handle multiple arguments, but a quick search on MSDN should help. My guess is that you'd have to do a little bit of processing yourself: others on the forums may be able to help you more.
Also, remember to #include <process.h>, or it won't compile.
Don't worry about ending the thread: once the function returns, the thread is terminated by Windows.

Just because its Win32, doesn't mean you have to use its API. I prefer writing non-platform specific code if I can.

I wrote the plug-in in VB, so there is no point trying to use platform independant APIs The SetTimer call is working just fine, but I'm still having that StartVideo problem no one seems to know anything about.

CMI:
I didn't realise you were using VB, as you mentioned the IMessenger interface, which is C++. Reading back over the thread, I see that you are indeed using VB, so anything I gave you for C++ doesn't actually apply. O well, still could be useful.

TB:
I stand by my original comment. Anyway, which uses less resources: standard library function, or Win32 API?

How about we forget about all this and head over to me StartVideo thread

Good idea.

offtopic: Admins, would a split be useful here?

Do you know for certain though? I know I don't. Why not run a little test, say create 1000 threads using each method and measuring the resource usage some way.
