[C++知识库]MFC工程报错，C2664，CString类型变量TempStr.Replace(“ “““)；编译出现问题的解决方法

上代码例子

void CAES_GCM_CTRDlg::OnBnClickedButtonEnc()
{
	// TODO: Add your control notification handler code here
	char ch[100];
	BYTE KeyArry[50];
	CString TempStr;
    int tempLen = 0;

	
	m_key.GetWindowText(TempStr);
	TempStr.Replace(" ","");
	tempLen = TempStr.GetLength();
	if (tempLen > 96)
	{
		if (MessageBox(_T("确定退出吗"), _T("提示"),MB_YESNO|MB_ICONWARNING)  == IDNO) 
		return; 
	}
	memcpy(ch, TempStr.GetBuffer(0), TempStr.GetLength());

}

其中TempStr.Replace(" “,”");编译出现下面错误：

Error 3 error C2664: ‘int ATL::CStringT<BaseType,StringTraits>::Replace(wchar_t,wchar_t)’ : cannot convert parameter 1 from ‘const char [2]’ to ‘wchar_t’ g:\COS Project\Google Smart Tap\AES_GCM\AES-GCM-CTR\AES_GCM_CTR\AES_GCM_CTR\AES_GCM_CTRDlg.cpp 130 AES_GCM_CTR

解决方法:
右键工程属性=>Configuration Properties=>General=>Character Set=>选择Not Set，然后应用确定，编译就可以了。
