Basic usage of MFC thread afxbeginthread, passing multiple parameters

UI Threads ：

CWinThread* AFXAPI AfxBeginThread(
CRuntimeClass* pThreadClass, // from CWinThread Derived RUNTIME_CLASS class 
int nPriority,				 // Specify thread priority , If 0, Is the same as the thread that created the thread 
UINT nStackSize,			 // Specifies the stack size of the thread , If 0, Is the same as the thread that created the thread 
DWORD dwCreateFlags,// Create logo   If it is CREATE_SUSPENDED  The thread is created in the suspended state , Thread suspended after thread creation , Otherwise, the thread starts executing after it is created 
LPSECURITY_ATTRIBUTES lpSecurityAttrs)// Thread security properties ,NT Next useful .

Worker threads ：

CWinThread* AfxBeginThread(AFX_THREADPROC pfnThreadProc,// Entry function , Statement ：UINT MyThreadFunction(LPVOID pParam）
LPVOID lParam,							// Parameters passed into the thread , Its type is ：LPVOID, So you can pass a structure into the thread 
int nPriority = THREAD_PRIORITY_NORMAL,	// Thread priority , Generally set as  0 . Let it have the same priority as the main thread .
UINT nStackSize = 0,					// Specify the stack size of the newly created thread . If  0, The newly created thread has a stack the same size as the main thread 
DWORD dwCreateFlags = 0,				//CREATE_SUSPENDED： After the thread is created , Will be suspended , Until the call ：ResumeThread
										//0： Start running after creating the thread .
LPSECURITY_ATTRIBUTES lpSecurityAttrs = NULL // If  NULL, Then the newly created thread has the same security as the main thread .
); 										// Return value ：  When successful, it returns a pointer to the thread object of the new thread , otherwise NULL.

Worker threads use ：

1. Passing in a single parameter

1. Thread handler

void* Camera::CodeSaveThread(void* pParam)
{
    
    CString Codes = *(CString*)pParam; // The typeless pointer becomes an integer pointer 
    //...
    //...
    AfxEndThread(0);
    return 0;
}

2. Start a thread ：

    CString Code = _T("test");
	AfxBeginThread((AFX_THREADPROC)CodeSaveThread, (void*)&Code, THREAD_PRIORITY_IDLE); // Keep a log  

2. Pass multiple parameters （ Structure ）

1. Thread handler

struct LogStruct        // Save log structure 
{
    
    CString LogName;
    CString DataStr;
};
void* Camera::CodeSaveThread(void* pParam)
{
    
    LogStruct LogStru = *(LogStruct*)pParam; // The typeless pointer becomes an integer pointer 
    CString LogName = LogStru.LogName ;
    CString Codes = LogStru.DataStr; 
    //...
    //...
    AfxEndThread(0);
    return 0;
}

2. Start a thread ：

CString Code = _T("test");
LogStruct LogStru;
LogStru.LogName = _T("Log");
LogStru.DataStr = Code;
AfxBeginThread((AFX_THREADPROC)CodeSaveThread, (void*)&LogStru, 0);   // Keep a log
