Thanks in advance

Use SendInput (not available on Win95) or keybd_event.

how do you direct the keyboard event generated by keybd_event to particular window.

What's the easiest way for an app to know when a machine (say, a laptop) has come out of hibernation? In CE there is the WM_HIBERNATE message but I can't seem to find a win32 equivalent.
cheers,

Hi,
Can anyone please give me an example of the function:
QueryPerformanceCounter()??
What I know is that it is related to "high-resolution performance...". But, I don't really know how to use it.
Thank you!

Thank you! I've actually checked that out already.
And, I've found an even simpler program about that.

Hi,
I just wonder if my program is really protected by CriticalSection:
My program uses multithreading......and require to access many array. Since I want to prevent same time access to an array item by several threads, I centralize all operation that modify the content of array in one function. Here is the structure of this function:
int function(....)
{
CCriticalSection cs;
cs.Lock();
//code for modifying array here....
cs.Unlock();
}
However, my thread function has some codes to "read" the array content in their own thread function.
My question is: Is it OK???
I have run my program. Sometimes OK, sometimes has error (especially i choose to run so many threads...)
Any suggestion to help me debug???

NO
CCriticalSection cs; <--- this is now a temp variable
Make it a member of your class or make it global

I tried to declare it in StdAfx.h and .cpp:
In StdAfx.h:
extern CCriticalSection cs;
In StdAfx.cpp
CCriticalSection cs;
But i have this error message:
"error C2146: syntax error : missing ';' before identifier 'cs'
fatal error C1004: unexpected end of file found"
What happened??
I tried to put it in ....Dlg.h...........same error.........
Can you help me!!!????
Thanks!!!!

Dont put it in stdafx.h
Cause when you put it on top, the compiler hasn't encountered the included header files yet
Make it a member variable of the class where you are using the critical section

No, because you're creating the critical section on the stack. Each thread has its own stack, so when two threads enter the function they use different critical sections.
You need to have one critical section and then access it in all threads.

Hi,
Thanks for all your replies.......
But I'm not quite understand........can you give me some example codes???
Thanks

Tell you what, since you seem to have trouble making it a member of your class, for whatever reasons do this then :-
Make it a member of the CWinApp derived class.
Now use AfxGetApp(), cast the pointer returned to your CWinApp derived class and access the critical section variable.

I'm not quite understand how to make it a member of the CWinApp, or even make it global. Can you give me some examples??
LOTS OF THANKS!!!!!!!!!

Dear Friend
I don't know whether this is going to solve your problem , This is how to make a variable global. double click the "theApp" Global variable in your project.then you can see the declaration
eg:
CMyApp theApp;
//Put your variable as follows
CCriticalSection cs;
//Now this is global
Then go to the implimentation file of the class where you want to use this varialble,and put is as follows
eg:
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
//Global Variable, Now use this in your function
extern CCriticalSection cs;
// CMyApp
BEGIN_MESSAGE_MAP(CMyApp, CWinApp)
ON_COMMAND(ID_HELP, CWinApp::OnHelp)
END_MESSAGE_MAP()

If you just want to protect what is happening inside this function then simple change it to:
static CCriticalSection cs;
As others have said it can't be on the stack under any circumstances.

I use the following code:
/////////////////////////////////////
this->GetDC()->SetBkColor( RGB(0,0,255) );
this->SendMessage( WM_PAINT, 0, 0 );
//////////////////////////////////////
But no efforts, what's the matter?
I'm amumu, and you?

hi,
Take a look the structure of my array first:
struct WAITQUEUE_STRUCT
{
CWinThread* pThread;
int LockType;
LARGE_INTEGER start_time;
};
struct LOCK_TABLE
{
CWinThread* CurrentThread;
int CurrentLock;
std::vector<WAITQUEUE_STRUCT> WaitQueue;
};
std::vector<LOCK_TABLE> LockTable;
In my program:
std::vector <WAITQUEUE_STRUCT>::iterator Iter;
for (int i=0; i<NumOfDBObject; i++)
{
Iter = LockTable[i].WaitQueue.begin();
if (*Iter.pThread != NULL) <- one of the error here
{ .......
.......
.......
i got the error message :
"error C2228: left of '.pThread' must have class/struct/union type"
What happened??????
