did you have omitted this?
#ifndef DLLEXPORT
#define DLLEXPORT _declspec(dllexport)
#endif
DLLEXPORT void FxA(bool bValue);
in your header file... (I repeat: you must to add this header file to your service project)

dear all,
i am using the following code to get root directory and then find out the file system.
but it gives an error Specified Path iS Invalid!
what wrong have i done!
is there any other (better) way to do it!
plz. help!!! 
DWORD dwError;
CString RootPathName;
CString RootDir;
UINT i = GetWindowsDirectory(RootPathName.GetBuffer(MAX_PATH),MAX_PATH);
RootDir= RootPathName.Mid(0,2);
AfxMessageBox(RootDir);
BOOL bFSResult = GetVolumeInformation (RootDir.GetBufferRootDir.GetLength)),
NULL,
0,
NULL,
NULL,
NULL,
FileSystem.GetBuffer(MAX_PATH),
MAX_PATH);
dwError = GetLastError();
AfxMessageBox(FileSystem);

This is my code for it : (I don't prefere using CString with APIs and this is just because I feel it's easier to use char)
char WinDir[MAX_PATH];
char Vol[4];
char FileSystem[10];
UINT i = GetWindowsDirectory(WinDir,MAX_PATH);
AfxMessageBox(WinDir);
strncpy(Vol,WinDir,3);
Vol[3]='\0';
AfxMessageBox(Vol);
BOOL bFSResult = GetVolumeInformation (Vol,
NULL,
0,
0,
0,
0,
FileSystem,
10);
AfxMessageBox(FileSystem);

Hi !
I started yesterday to write my first MDI app (with MFC, let's get at it slowly ). This is a kind of text viewer, maybe editor (Yes, another one  but i think it's a good example to start). You may say there is not much to do, but ...
Anyway, my first problem is that i'd like the child windows to be maximized when a document is opened. Currently the child window is about half the size of the screen, in the middle. Since the main frame is maximized at startup, i'd like the child win to be maximized also.
So i intercetpted the CREATESTRUCT from the PreCreateWindow in CMDIChild class, and did :
cs.style|=WS_MAXIMIZE;
But this would not change anything. I tried this in several other places, and also with ShowWindow(WS_MAXIMZED), but no way, my win is still not maximized. What's wrong ?

Try:
ShowWindow(SW_MAXIMIZE);
((CMDIFrameWnd *)AfxGetMainWnd())->RedrawWindow(NULL, NULL,
RDW_INVALIDATE | RDW_ALLCHILDREN);
or MDIMaximize().

Thanks. I'll give it a try.
I did not think it was that complicated  : your hint seems a little bit tricky (Do not get me wrong, I just mean that I usually use the AfxGet**() functions when I did not get anything else to work ). Is it possible that the Child Window initially have wrong system metrics (so that it thinks that the maximized size is the size that it actually has on startup, i.e. not the screen size ) ?
[Look at MSDN]
Oh, I think MDIMaximize should be what I need.
Big thanks

I don't know.
I have tried to overwrite MyChildFrame::Create and to modify the style before calling CMDIChildWnd::Create but nothing happened. The call to ShowWindow(SW_SHOWMAXIMIZED) - which, by the way, equals MDIMaximize()  - remained a must.
But, if you want to do it with a SDI window - 100% API stuff - the metrics work perfectly and are not forgotten. You have to call ShowWindow(SW_SHOW) and the window appears as maximized. This seems to be the natural windows' behaviour - for API SDI, at least.

Ok tried yesterday evening. It was really that the Child window had the wrong system metrics for it to work with modifying the style in the CREATESTRUCT of PrecCreateWindow().
Also tried with MDIMaximize() surprisingly did not work, whereas ShowWindow(SW_SHOWMAXIMIZED) works perfectly (In fact, i can rememeber i tried ShowWindow(SW_SHOWMAXIMIZED) in PreCreateWindow instead of Create before posting my initial thread, and this did not work. Solution was to do it in Create instead. 
Well, it works, so lots of thanks for your help anf for you having bothered to try out.

HIMAGELIST hSysImageList = (HIMAGELIST) SHGetFileInfo((LPCTSTR)(LPCITEMIDLIST)pidl,
0, &sfi, sizeof(SHFILEINFO), SHGFI_PIDL | SHGFI_SYSICONINDEX | SHGFI_SMALLICON);
theApp.m_smallSystemIcon.Attach(hSysImageList);
ZeroMemory(&sfi, sizeof(SHFILEINFO));
hSysImageList = (HIMAGELIST) SHGetFileInfo((LPCTSTR)(LPCITEMIDLIST)pidl,
0, &sfi, sizeof(SHFILEINFO), SHGFI_PIDL | SHGFI_SYSICONINDEX | SHGFI_LARGEICON);
theApp.m_largeSystemIcon.Attach(hSysImageList);
}
CMainFrame::~CMainFrame()

theApp.m_smallSystemIcon.Detach();
theApp.m_largeSystemIcon.Detach();
theApp.SalvaListe();

I'm using softice version 3.2.
I want to set history buffer size to 2048 KB.
I try to set it with that value, and then reboot my machine.
But softice keep the history only about 200 KB.
I don't know why? Can you tell me how to set history buffer size to 2048 KB?
Thanks.

Back in my BeOS days, I was exposed to a faster mutex implemenation which coupled an atomic_add with a semaphore. The implementation was (in pseudo code):
Mutex constructor:
int_avail_count = 1;
sem_avail_count = 0;
Lock:
atomic_add( &int_avail_count, -1 )
if int_avail_count was 1: return
else (someone else held the mutex): wait on semaphore; for first waiter, sem_avail_count goes to -1
Unlock:
atomic_add( &int_avail_count, 1 )
if int_avail_count was 0: return
else (someone else was or would soon be waiting on the semaphore): release the semaphore; for last waiter, sem_avail_count goes to 0 again
I just encountered a situation in a Win32 app where I have a body of data which must be protected by a critical section, but will be hit often from a high-priority thread. There will be very little if any contention for this data so it's a prime candidate for this construct, which saves a trip into the kernel for a mutex acquisition. I'm therefore looking into using InterlockedIncrement/InterlockedDecrement, CreateEvent/SetEvent/WaitForSingleObject to implement this design for windows. But... On BeOS, mutexes and events were implemented as generic semaphores involving a count. It was perfectly legitimate for a thread to release a semaphore even if it doesn't own it (that was the client's responsibility to enforce). But since ReleaseMutex is documented with: "The ReleaseMutex function fails if the calling thread does not own the mutex object" it requires the use of an event. To use this design on Windows requires an event, not a mutex, and would depend on a behavior, so now the question:
First, if multiple threads are blocked on an event and a single call is made to SetEvent, does one waiting thread unblock, or all? If all, this design is not feasible. If one, on to the next question...
Second, if multiple threads are blocked on an event, and a single call is made to SetEvent, are they released in FIFO order, or arbitrary? Hopefully FIFO, as the design also depends on that behavior.

It depends on the type of event. For auto-reset events, only one. For manual-reset, all waiting threads are released. The SetEvent() docs explain it in more detail.
Second, if multiple threads are blocked on an event, and a single call is made to SetEvent, are they released in FIFO order, or arbitrary?
Arbitrary, there is no guarantee on which thread gets woken up.

Rereading the CreateEvent docs, I do see now the statement about a single thread being released, thanks. In the process I noticed something else that I'd overlooked: that there are semaphore functions at all. With windows I'd only used events and mutexes per se and hadn't noticed semaphores. Switched to the semaphore now, works great.
Thanks,
Brian

Hello,
I'm trying to arrange more than 100000 items in the listview with icon style. I use ListView_SetItemPosition32 and it works fine for fewers items but having problem to arrange more items. Some items (such as 3xxx - 5xxx) goes to the top of the first item I've inserted (index 0 item) and they got -y position in the view. I've never assign nagitave position value to any item but how come the y came out to be nagitave.
Any idea why? TIA!
thanks!
