Hi, I read the MSDN online and get the following sample of using AfxBeginThread:
UINT MyThreadProc( LPVOID pParam )
{
CMyObject* pObject = (CMyObject*)pParam;
if (pObject == NULL ||
!pObject->IsKindOf(RUNTIME_CLASS(CMyObject)))
return 1; // if pObject is not valid
// do something with 'pObject'
return 0; // thread completed successfully
}
// inside a different function in the program
.
.
.
pNewObject = new CMyObject;
AfxBeginThread(MyThreadProc, pNewObject);
.
.
.
I understand that.....but :
1. if I want to create 50 threads that doing the stuff in MyThreadProc(), how can i do it? Add a for loop to create 50 times???
2. If I want to suspend 10th thread, how can i identify the 10th thread and suspend it?
3. Same as 2....to do resume and kill the thread.
Thank you very much !!!

I think you can create 50 seprate thread instead of creating one and doing 50 thread in it,then when you want to suspend 10th of them,it is so easy.Another easy way is set timer and make it work for example for each 1 second for 50 seconds.Hope that help.

Thanks for your reply!
Yes....I need to create 50 separate threads (liked 50 different transactions). Since my program is going to simulate the DBMS behavior, in the MyThreadProc() there should be some algorithm to choose whether the current operation of this transaction is READ or WRITE. In this case, all 50 threads will use the same MyThreadProc() and i don't need to make 50 different MyThreadProc(). My question is,
1. Can i create these thread by:
for (i=0; i<50; i++)
{
pNewObject = new CMyObject;
AfxBeginThread(MyThreadProc, pNewObject);
}
2. How to identify Xth thread after creating 50 threads?
3. What parameter I need to put in order to suspend/resume/kill the 10th (or Xth) Thread? Because let say, one thread A (transaction) is READING a data object, and another thread B wants to WRITE the same data object. In this case, thread B needs to wait until thread A finish. So I have to suspend thread B......and wait....then resume.
So, should I call AfxGetThread()???? SuspendThread()??? ResumeThread()????
Thanks!!!!

AfxBeginThread will return the CWinThread* for the thread started. That will identify each thread. You can have an array of CWinThread*s

How does it works?
Can I use CAsyncSocket and just make a simple C/S app????
How?
I want to make a Client/Server either by using MFC or Win32 API
And it going to work over the internet!

The machine running the server must be accesible from the internet. Other than that there is not much difference.

So you mean, that example application from "Sams Teach Yourself VC++ in 21 days" will work if I put the server on a computer with Internet acces and then call the server with the IP and bla bla....???? Perhaps you don't know how that example works?
But I don't need to set a specific flag to the Create or something?
You article for example... Can I use it over the Internet?

I never saw that book, but I expect it to work

p.s. I am surprised that a 21 day VC++ book has a chapter on winsock!!! or were they teaching CSocket stuff?

Well, it talks about CAsyncSocket class and how to create a simple Client/Server app to send messages etc.......

I have created a simple MDI application with the MFC class wizard. At the moment I have only one view and one document. The view has CListView as a base class. I have disabled the new file option on startup by using
cmdInfo.m_nShellCommand = CCommandLineInfo::FileNothing;
The user can either call a add menu option that displays a dialog box with which they can add data to the database, or they can pick a view menu option which will allow them to view all the data added on that particular day. My problem is calling the view from the mainframe menu option. I have read several articles but they all deal with adding documents and views and then swopping between them. I know I'm probably being very dense but have tried the whole of yesterday with no success. .
This is the code I'm using to initialize the List view in myView::OnInitialUpdate.
DWORD dwExStyle;
CRepPartDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
//CActionsApp *pApp = (CActionsApp*)AfxGetApp();
CListCtrl& m_List = GetListCtrl();
dwExStyle = m_List.GetExStyle();
dwExStyle |= LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES;
m_List.SetExtendedStyle(dwExStyle);
m_List.SetBkColor(RGB(255, 255, 255));
ASSERT(m_List.GetBkColor() == RGB(255, 255, 255));
m_List.InsertColumn(0,_T("Share"),LVCFMT_LEFT,160);
m_List.InsertColumn(1,_T("Status"),LVCFMT_LEFT,90);
m_List.InsertColumn(2,_T("Action Date"),LVCFMT_LEFT,90);
m_List.InsertColumn(3,_T("Book Date"),LVCFMT_LEFT,90);
m_List.InsertColumn(4,_T("Comment"),LVCFMT_LEFT,160);
Someone has suggested calling OnFileNew() from my menu handler but no success. Please help! Any suggestions will be more than I have already!
Grasp it but you cannot get it!

Who has used the regexp object in system32\vbscipt.dll to parse the text string. I have tried it and make it work!
But i don't know why i can get only one match(that is the matches.GetCount()==1), even there are many exist. The next is my code:
void CInetSessionDlg::ParsePage(CString szPattern, CString szContent){
try{
if(m_regExp.CreateDispatch(__uuidof(RegExp)) == FALSE)
{
AfxMessageBox("CreateDispatch Failed!");
return;
}
m_regExp.SetIgnoreCase(TRUE);
m_regExp.SetPattern(LPCTSTR(szPattern));
if(m_regExp.Test(LPCSTR(szContent)))
{
ISubMatches matches = m_regExp.Execute(szContent);
for(long i = 0; i < matches.GetCount(); i++)
{
IMatch2 match = matches.GetItem(i);
CString strLink = match.GetValue();
m_cbHref.AddString(strLink); }
}
}
catch(_com_error& e)
{
AfxMessageBox("Com Error occurred!" + e.Description());
return;
}
}
in this implementation file's header file:
i defined the RegExp(copied from the file RegExp.tlh got from vbscript.dll)
struct __declspec(uuid("3f4daca4-160d-11d2-a8e9-00104b365c9f"))RegExp; // [ default ] interface IRegExp2
Why? Who can tell me how to use vbscript.dll in VC++ 6.0
thanks a lot!

ROTFL - this is EXCELLENT 
Try putting returns between your lines of code. Does it appear more readable to you like this ?
I'm sorry, I can't answer your problem, but anyone who can will be more likely to if your post is easy to read IMO.
Good luck.

Oh, I used an & and lt or gt to get < >, by typing in <pre>, you coloured the bottom of your post. If you use stuff that looks like HTML tags, check the 'display this message as is' option, or they get stripped as HTML, and in this case, used. OTherwise, use & lt and & gt without the space to do < and >.

Hi,
I am reading the book Programing Windows with MFC,but the example(The Hello Application) that it gave in chapter 1 cannot be compiled in the vc++ 6,it shows the informations below:
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
libcd.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/Hello.exe : fatal error LNK1120: 3 unresolved externals
Error executing link.exe.
Did the codes the book gave wrong? Or I should do anymore?
the codes are listed below:
Hello.h
class CMyApp : public CWinApp
{
public:
virtual BOOL InitInstance ();
};
class CMainWindow : public CFrameWnd
{
public:
CMainWindow ();
protected:
afx_msg void OnPaint ();
DECLARE_MESSAGE_MAP ()
};
Hello.cpp
#include <afxwin.h>
#include "Hello.h"
CMyApp myApp;
/////////////////////////////////////////////////////////////////////////
// CMyApp member functions
BOOL CMyApp::InitInstance ()
{
m_pMainWnd = new CMainWindow;
m_pMainWnd->ShowWindow (m_nCmdShow);
m_pMainWnd->UpdateWindow ();
return TRUE;
}
/////////////////////////////////////////////////////////////////////////
// CMainWindow message map and member functions
BEGIN_MESSAGE_MAP (CMainWindow, CFrameWnd)
ON_WM_PAINT ()
END_MESSAGE_MAP ()
CMainWindow::CMainWindow ()
{
Create (NULL, _T ("The Hello Application"));
}
void CMainWindow::OnPaint ()
{
CPaintDC dc (this);
CRect rect;
GetClientRect (&rect);
dc.DrawText (_T ("Hello, MFC"), -1, &rect,
DT_SINGLELINE | DT_CENTER | DT_VCENTER);
}
//I am sorry to interrupt you but I am a beginner,so if you know the answer,please tell me,thanks.
YES, I am here.

You need to link with the MFC library [either statically or dynamically]

If you're writing this from a blank project, you need to read carefully how to set it up. I've learned what all the bits the wizard gives me do, but I've never started a project except through the wizard - it just makes more sense to me to let the compiler generate boiler plate code, although, as I say, I've also had a good dig through it and can do a lot of the wizard stuff by hand if I want/need to.

There is not much to setting it up actually
1. Include the MFC headers
2. Link with MFC [statically or dynamically]
That's all...

Fair enough, but obviously the book would have told him how to do that and he's missed it.
