Code Using Multithreading

[arunkr6]

This is my first program in VC++.net. Am developing a GUI appln tool for receiving datas from a Processor based PCBs. Here i have to use Multithreading. I've no previous experience on using Thread. From the help of MSDN, I've tried to make it. The code layout is as follows...

<code>
void OnBnClickedReceive()
{
DWORD threadId;
int value = 10;

CreateThread(NULL, 0, File_edit, &value, 0, &threadId

}

DWORD WINAPI File_edit(LPVOID lp)
{
// processing....
}

</code>

But the Error messages came as

'CNewSerialPrintDlg::FileData_edit': function call missing argument list; use '&CNewSerialPrintDlg::FileData_edit' to create a pointer to member'


Not getting any ideas to fix it.. Plz help n give me details for a thread development.

Didn't you notice that the code tags didn't work? Who knows what else you don't notice. If you want to be a programmer you'll have to learn to pay attention to detail.

Sorry i was in hurry when I posted that..

Am reposting my exact codes..Plz help me.

void CNewSerialPrintDlg::OnBnClickedReceive()
{
	// TODO: Add your control notification handler code here

	HANDLE m_RecvThread=NULL;
	DWORD	ThreadID = 0;
	m_RecvThread = ::CreateThread(NULL,
				0,
			         FileData_edit,
			NULL,
			0,
			&ThreadID);
}

DWORD WINAPI CNewSerialPrintDlg::FileData_edit(LPVOID lp)
{
	//bla.. bla...
               return 0;
}

The error message is:

'CNewSerialPrintDlg::FileData_edit': function call missing argument list; use '&CNewSerialPrintDlg::FileData_edit' to create a pointer to member

Plz help me to fix it

The thread function needs to be static or outside the class scope.

[arunkr6]

Static means I have to declare all the variables n member functions as static. Am I right?

thatś not easy.... So scope out of class means. Should I declare it as private???
plz specify??

[Krishnaa]

Out of class means a public function. You can also try the CWinThread class instead of creating the thread using CreateThread API.

[arunkr6]

I've declared the thread function as public only..

Sorry 2 say,it's my first VC++ project. So how may I use WinThread().... plz. and will it fix the error coming.

In my developing tool,have to identify certain datas all time continuously..thats wy I chose Multithreading by using CreateThread(). And the process function declared as FileData_edit. All parts u may c from the code posted..

[Krishnaa]

The function FileData_edit can not be non-static, it has to be global function (without a class) or static member function of the class.

I am sorry but I think as a part of learning, you should try fixing it from the information I am supplying.
