trouble with _beginthread

NoName II

_beginthread(CopyProcessTh, 0, NULL);//error C3867: 'CDlg::CopyProcessTh': function call missing argument list; use '&CDlg::CopyProcessTh' to create a pointer to member void CDlg::CopyProcessTh(void * p) { dlg=new CCopyInterface(this); if (m_copiedFile.GetLength()!=0) { dlg->CopyFileFunct(m_copiedFile,m_leftFolder); } }

Made the CopyProcessTh as a static in the class which returns UINT from the function which is recommended to terminate the thread. OR 2) Seperate out the function from the class with following prototype

UINT CopyProcessTh(LPVOID pparam)
{
//Do your Stuff here.
return 0;
}

Knock out 't' from can't, You can if you think you can :cool:

There was a recent change to C++ that says you can't write class_name::function_name to get a pointer to the function, you have to write &class_name::function_name

See void MyThread( LPVOID pv ); ... ... void CTest::RunThread() { _beginthread(MyThread,0,NULL); } void MyThread( LPVOID pv ) { CTest* m_Answer = (CTest*) pv; m_Answer->Modify(); } void CTest::Modify() { MessageBox("A"); }_**

I can't made CopyProcessTh as a static cause it should operate with nonstatic members.. as for the 2nd...error C3867: 'CDlg::CopyProcessTh': function call missing argument list; use '&CDlg::CopyProcessTh' to create a pointer to member

You meant _beginthread(MyThread,0,this); no ?

You can't pass a non-static member function to _beginthread. The reason is that static and non-static member functions don't have the same prototype. Non-static member functions have an implicit parameter that is passed: the 'this' parameter. Look at the post of WhyteSky for the 'workaround' to this problem.
