Why aren't those data at least process-specific so multiple applications could have used the functions in the DLL?
That would defeat the purpose of checking for idleness. If these variables were not marked as shared, each process that used the DLL would get its own copy of the variables, thus idle in one process might not be idle in another process.

I have a dialog which contains a CListCtrl to dislplay some information.
two cwinthreads from other dlg keep updating the data of the CListCtrl.
the CListCtrl's handle is passed to the threads and there is a Shared CriticalSection among these 3 objects.
when i close the dlg, i want to set a flg to inform the two threads that the list is destroyed. so i call in the exit event of the dlg:
lock.Lock();
destroyFlg = true; // the threads will check this flg before access the list
//and access to the list is protected by lock & unlock
lock.UnLock();
what happend is that , the dlg is hung. i traced and find it hung at lock.Lock();
there is only one crictical section and i am sure i have paired each lock() with a unlock(). why this still happend?
Some one knows please help me. thanx a lot.

You can avoid a whole lot of problems by simply having these other two threads post a message back to the main thread (the one that actually owns the GUI). Locking and synchronizing are a headache if not done 100% correctly.

Consider using a wrapper class to lock your object.
See following code:
http://code.axter.com/sync_ptr.h
The above wrapper class will automatically lock and unlock your object, so you don't have to worry about forgetting.

when u click on any variable name, we'd find "go to declaration","go to reference".. but if u click on it, its not taking the cursor to the decl or ref, its simply saying "The Symbol 'VAL1' is not defined".. but i've declared everything inside the class n i get no errors.
and code assistance is not coming too... when you type the .(dot) after an object or something, nothing is displayed. should we change any setting in the IDE?
thanks in advance

do you use VC++ 6 or VC++.NET 2003 ? (VC6 i think)
you have to make the pdb file when it ask you to...

Did you declare the variable in a header or a code file ?
The class browser only looks in header files, certainly on VC6.0.

Close down your workspace, Delete the project.ncw file and restart your computer. Next time when you open your project the Intellisense will be working

Thanks Chris,
I am looking for the implemenation of _stprint function for a embedded device. If you can point some source which gives a starting point it will be great.
Thanks in advance,
