字符串截取GUID

//20161014

今天改写GUID码

所谓GUID              mfc产生一个随机的GUID

代码如下

CString GUIDGen()
{
    CString sguid;
    GUID guid;
    HRESULT hResult = CoCreateGuid( &guid );
    if ( S_OK == hResult )
    {
        CComBSTR bstrGuid( guid );
        sguid = bstrGuid;
    }
    return sguid;
}

产生一个随机码guid

现在要去掉其中的“{"和"}”

更改代码

CString GUIDGen()
{
CString sguid="";
GUID guid;
HRESULT hResult = CoCreateGuid(&guid);
if (S_OK == hResult)
{
CComBSTR bstrGuid(guid);
sguid = bstrGuid;
int first = 1;
int last = sguid.GetLength() - 2;
sguid = sguid.Mid(first, last);
}
return sguid;
}

返回值去掉｛｝
