Did you search for a CodeProject's article? I found: "An SMPPLIB with COM Support".

I'm currently working on a rewrite of my most recent article Monitoring and Controlling a Recursing Function in a Worker Thread and would love to know your opinions on the fowing block of code I use in the worker thread...
do {
Sleep(1);
}while (pMyView->m_strCurFile != pMyView->m_strConfirm);
This has the effect of slowing things up enough so that the main thread can display a gratifyingly fast moving display of files flash past in the text box on the dialog. I was going to say that, without it, the dialag doesn;t display any file information until the thread has stopped running but I've just tried it and, in fact, with out it I get an Access Violation error!
It doesn't seem like a very nice bit of code to me. Could it be replaced with WaitForSingleObject or something, somehow?
Interestingly, if I try and speed the thread up by putting in an extra mod test so that it only runs every tenth loop...
if (n % 10 ==0){
do {
Sleep(1);
}while (pMyView->m_strCurFile != pMyView->m_strConfirm);
}
...this also causes problems...

In general Sleep is bad form, although as with any rule of thumb there are exceptions. Unfortunately, from what I've seen your code isn't one of them.

But what's you're problem? From what I gather, what you should be worried about is what's causing the access violation. Never stop a crash by poking around blindly till it stops: lose the Sleep and find the cause of the real problem (the access violation). The first thing I'd do is kill the Sleep, run the code under a debugger and get a stack trace of the access violation. I suggest posing it.Steve

Thanks for this Stephen, you have hit the nail on the head, I think, regarding the access violation. I have had a reply indicating that my use of CString objects is causing this. I will investigate this.

I took a brief look at your article. I have some humble comments/observations.
1.) Yes you should get rid of the call to Sleep. I have never found any use for this API call and in my opinion it is probably the most abused function on planet Earth. I recommend the following:
a) Add: HANDLE hEvent; to your CFormView.
b) Call hEvent = CreateEvent(NULL,FALSE,FALSE,"Your-GUID"); in your constructor.
c) Call SetEvent(hEvent); in your OnCURFILEEVENT message handler.
d) Replace the Sleep(1) with: WaitForSingleObject(hEvent,1000); and then reset the event with ResetEvent(hEvent); immediately afterwards.
2.) Regarding your access violation... I instantly recognized the problem. You are incorrectly accessing a CString object that lives inside your CFormView from the worker thread. CString is NOT thread-safe. You need to replace the pMyView->m_strCurFile assignment with a message function such as SendMessageTimeout[^] and this will fix the Access Violation in your article.
Best Wishes,

I am very grateful to you, David, for looking at my code. You only looked at it briefly but were able to provide me with these very specific points of help. It's humbling for me because it will take longer for me to try them out than it took for you to look through my code, understand what I was trying to do and make these suggestions. I will go through them carefully, though. You clearly know what you are writing about.

Hi Dave,
I've got the project working with the following alterations...
Here is the sending code in MakeListing...
CString* pString = new CString(FindFileData.cFileName);
SendMessageTimeout(pMyView->GetSafeHwnd(), CURFILEEVENT, (WPARAM)pString, 0, 0, 1000, 0);
delete pString;
Here is the receiving function...
LRESULT CRecThread2008_64Dlg::OnCURFILEEVENT(UINT wParam, LONG lParam)
{
CString* pString = (CString*)wParam;
CString tempStr = pString->GetBuffer();
m_iNoFiles++;
CString tString=LPCTSTR("");
tString.Format(_T("%d"),m_iNoFiles);
m_strNoFiles = tString;
m_strFileList= tempStr + _T("\r\n")+ m_strFileList;
m_strFileList = m_strFileList.Left(500);
UpdateData(FALSE);
return 0;
}
And it works without the sleep block - so I have got rid of that!
I think I getting near to a point where I can start to rewrite the article...
Thank you for your help with this,
Ben.

David, the code and article is rewritten, now. Thanks so much for your help. I used SendMessageTimout and it worked nicely!
Thanks,
Ben.

Hi all,

I need to find out how to hide your number, so that the receiver will either see a message with no sender or even better a sender with characters as their number, e.g From: "Service".
i want if any recepient receive my SMS ,SMS display a Name that is i m set instead of my phone number.
please help me for this.
tahnks.

I knew helping you with SMS was going to be an issue - I can think of no good/nice/honset reason for doing what you suggest - I urge anyone else here not to respond if they know a way of doing it.

| Fortunately, for the rest of us, this feature is not allowed, as message identification is controlled by the network provider. Short answer, you cannot do it. txtspeak is the realm of 9 year old children, not developers. Christian Graus

Me think he wants to create a virtual desktop, larger than the actual desktop), so you can scroll the whole desktop and place application in position outside of the screen "physical viewport".
I think I've seen this on linux.Watched code never compiles.
