关于在Winform中新建线程的问题

[lsxsxs]

这里人气比较高，来这里问下。我用的是VS2008，建的程序是个Winform，但是用的是VC++语言。想点击一个按钮之后把数据添加到Access数据库里去，但是由于数据量大，程序就直接死了。想在按钮事件中新建一个线程来添加。但是始终有问题，就在ThreadStart的时候。

ThreadStart^ threadDelegate = gcnew ThreadStart(Add());
            Thread^ thread = gcnew Thread(threadDelegate);
            thread->Start();

其中Add是一个函数，查找了一些C#的方法，把Add后面的括号去了也不行。谁能帮忙解决一下啊。谢谢

Thread t = new Thread(new ThreadStart(Add));
t.Start();

[Quote=引用 1 楼 xiaoqiang321 的回复:]
Thread t = new Thread(new ThreadStart(Add));
t.Start();

这样就可以的

C#这样是行，不过我用的是C++，不加括号的话，还会多一个错误，就是Add函数错误。这里有C++开发Winform的人吗

vc.net 我真觉得是费力不讨好！
你还是用C#写这段吧。

// [C++]
// Compile using /clr option.
using namespace System;
using namespace System::Threading;

// Simple threading scenario:  Start a Shared method running
// on a second thread.
public ref class ThreadExample
{
public:

   // The ThreadProc method is called when the thread starts.
   // It loops ten times, writing to the console and yielding 
   // the rest of its time slice each time, and then ends.
   static void ThreadProc()
   {
      for ( int i = 0; i < 10; i++ )
      {
         Console::Write(  "ThreadProc: " );
         Console::WriteLine( i );
         
         // Yield the rest of the time slice.
         Thread::Sleep( 0 );

      }
   }

};

int main()
{
   Console::WriteLine( "Main thread: Start a second thread." );
   
   // Create the thread, passing a ThreadStart delegate that
   // represents the ThreadExample::ThreadProc method.  For a 
   // delegate representing a static method, no object is
   // required.
   Thread^ oThread = gcnew Thread( gcnew ThreadStart( &ThreadExample::ThreadProc ) );
   
   // Start the thread.  On a uniprocessor, the thread does not get 
   // any processor time until the main thread yields.  Uncomment
   // the Thread.Sleep that follows t.Start() to see the difference.
   oThread->Start();
   
   //Thread::Sleep(0);
   for ( int i = 0; i < 4; i++ )
   {
      Console::WriteLine(  "Main thread: Do some work." );
      Thread::Sleep( 0 );

   }
   Console::WriteLine(  "Main thread: Call Join(), to wait until ThreadProc ends." );
   oThread->Join();
   Console::WriteLine(  "Main thread: ThreadProc.Join has returned.  Press Enter to end program." );
   Console::ReadLine();
   return 0;
}

以上是MSDN的例子

原来Winform里有个backgroundWork控件，用这个可以进行后台操作。公司太畸形了，要用这个四不像的东西开发。
