Hmmm - i think CheckTokenMembership is new to Win 2000, so I'd venture that some app installed a bad copy of msvfw32.dll on that NT machine.

Its a video for windows helper lib - I _think_ its not native to the OS, and some mulimedia apps may ship with their own copy...

MSN Messenger Send Message To

25-Feb-02 3:55

Hi there,
I would like to be able to invoke the "send message to contact window" of msn messenger from an About Dialog Box... Msn Messenger is of course supposed to be running and logged in.
The same thing could be great also with Yahoo Messenger...
Does anybody know how to do that ?
I heard about the IM interface from Exchange Server SDK... but don't know how to do...
Thanks

Ok,
thanks for your answer.
But could you be more precise regarding wich files I have to include or wich SDK I have to install cause I can't compile your code.
Also, I tried to find the COM object of MSN Messenger but with no success!
Regards!

Download messengerua.exe from this page. That has the API docs and the header file with the MSN IM interfaces.

I'm trying to create an MDI application to play around with OpenGL. I'm using the instructions at this link

http://www.codeproject.com/opengl/glenabledview.asp

under where it says:
Use
This article uses the trackball code introduced in the companion article A virtual trackball rotation controller .
To start experimenting OpenGL drawing you just need to follow these steps:

But its not working for me. Can someone possibly give me more elaborate instructions, I'm not sure what I'm doing wrong.

Is this is string really a string ?

Mauricio Ritter25-Feb-02 2:10

I was working on one of my projects and faced this problem:

I got a function that receives a LPTSTR parameter. This parameter can be a string, representing a file, or a resource (result of the MAKEINTRESOURCE).
It´s something like this:

void (LPTSTR lpszFile)
{
DWORD dwSize = strlen(lpszFile);
}

The problem is that if this string is the result of the MAKEINTRESOURCE macro, it´s not REALLY a string... it´s an resource ID. If I call strlen with this as a paremeter I´ll get a Access Violation.
The question is, how can I figure out if a string is a string or a resource Id ? I find a MACRO in MSDN docs called IS_INTRESOURCE but I tried to use it and it states that this macro is not defined. I checked the winuser.h and it´s not there. I don´t use the latest version of Plataform SDK, but I assume that this macro is defined there. Can someone gimme the definition of this macro or some other way to figure out if the string is really a string ?

Seen as a DWORD, an ID fake LPTSTR has its high order word set to zero:

inline bool is_resource_string(LPCTSTR lpctstr)
{
  return (reinterpret_cast<DWORD>(lpctstr)&0xFFFF0000U)==0;
}

(sort of, didn't try this).

MAKEINTRESOURCE returns a LPTSTR. But it should only be passed to resource functions. The best thing would be to re-prototype your function as :-

void blah(LPTSTR lpszFile,BOOL IsResource)
{
if(!IsResource)
{
DWORD dwSize = strlen(lpszFile);
}
}

That´s the solution I found... but that macro could be really usefull.

Another quick thread problem!

Jon Hulatt25-Feb-02 1:59

Hi,

Is there a "right" way for me to communicate with a CWinThread object???

My new, UI threaded smtp daemon now works like the following:

1. Primary thread has listening socket. In OnAccept(), I use a plain CAsyncSocket object to accept the new connection. I then detach this object from the socket in order to get the SOCKET of the connected socket.

2. Still in OnAccept, a AfxBeginThread a new instance of my CWinThread derived class. I set a member of this object to the SOCKET identifier i received on the Detach().

3. In my CWinThread classes initinstance(), i attach a member socket to the SOCKET i just shoved into the class.

Suprisingly, this seems to work. CWinThread's InitInstance doesn't seem to get called until after my OnAccept function has returned, hence the SOCKET handle in the CWinThread class is valid. But, it strikes me that this is pure fluke, the CWinThread could init itself at any time.

I thought about using a MUTEX to block the new threads execution in InitInstance, and release the mutex from the OnAccept function when i had finished detaching. But this seems crap too, since I'd have to use a named Mutex, because I cannot pass a handle to the CWinthread for the same reasons I can't get it a SOCKET.

Is there a better way to set up this object? An ideal way I think would be to have an overloaded constructor in the CWinThread derived class. But I *think* I can't do this becuase the class is dynamically created with RUNTIME_CLASS. Or is there a way to pass arguments to an overloaded constructor with dynamic creation????

Thanks

Jon

A safe way to perform object transfer is to create the thread with flag CREATE_SUSPENDED, do the transfer and then call CWinThread::ResumeThread.

Dear Fellow Programmers,
I have managed to implement the Drag/Drop mechanism. I have also been able to implement a toolbar from which bitmaps can be dragged.

However when I drag the bitmap image over the container window it is unable to drop (it just stays attached to the cursor) when the button is released (On LButtonUp) the bitmap doesn't stay on the screen - it disappears.

I think i need to implement some sort of method in either the OnDraw or OnLButtonUp member functions - and this where the problem really starts!!!.

Can anyone tell me whats going wrong?
