MFC CString转换为字符数组

Posted 2022-02-04 bcbobo21cn

VC6单文档工程；

void CZfszView::OnDraw(CDC* pDC)

	CZfszDoc* pDoc = GetDocument();
	ASSERT_VALID(pDoc);
	// TODO: add draw code for native data here
	//char sendBuf[256];
	//CString sendStr = "xxx";  
	//sprintf_s(sendBuf, sizeof(sendStr), (const char*)&sendStr);//数据到sendBuf
	//sprintf(sendBuf, sizeof(sendStr), (const char*)&sendStr);//数据到sendBuf
	
	//char ch[20];
	//CString str="abcd";
	//strcpy(ch,CW2A(str));

	CString str="hello!"; 
	pDC->TextOut(50,50,str);

	char ch[6]; 
	memcpy(ch,str,str.GetLength()); 
	pDC->TextOut(50,80,ch);

前面注释了的2段来自网上；均会出错；使用memcpy可以实现；
