我有两个问题：
第一：
'CMFCApplicationUpdateUIDoc :: Thread_no_1'：非标准语法；采用 '＆'创建指向成员的指针
秒：
如何正确更新CMFCApplicationUpdateUIView::OnDraw(CDC* pDC)中的line？我需要使用PostMessageW吗？还是？
MFCApplicationUpdateUIDoc.h
Thread_no_1MFCApplicationUpdateUIDoc.cpp
class CMFCApplicationUpdateUIDoc : public CDocument
{

};
MFCApplicationUpdateUIView.cpp
void CMFCApplicationUpdateUIDoc::StartCount()

int Data_Of_Thread_1 = 1;
HANDLE Handle_Of_Thread_1 = 0;
Handle_Of_Thread_1 = CreateThread(NULL, 0, CMFCApplicationUpdateUIDoc::Thread_no_1, &Data_Of_Thread_1, 0, NULL);
if (Handle_Of_Thread_1 == NULL)
ExitProcess(Data_Of_Thread_1);
}
DWORD CMFCApplicationUpdateUIDoc::Thread_no_1(LPVOID lpParam)
{
int Data = 0;
int count = 0;
HANDLE hStdout = NULL;
if ((hStdout = GetStdHandle(STD_OUTPUT_HANDLE))== INVALID_HANDLE_VALUE)
return 1;
Data = *((int*)lpParam);
for (count = 0; count <= 4; count++)
{
line = count;
}
return 0;
}
