error C2664: 'RFX_Long' : cannot convert parameter 3 from 'CString' to 'long &'

推荐答案

这是来自MSDN文档： http://msdn.microsoft.com/en-us/library/vstudio /s5b150wd%28v=vs.100%29.aspx [ ^ ]



'RFX_Long'：无法将参数3从'CString'转换为'很长&';



那么这意味着什么呢？你显然将一个参数（第三个）传递给RFX_Long，你传递的是CString类型，但是对long的引用被删除了加上没有从CString转换为对long的引用。



多长时间的引用是什么？

任何合法表达式允许作为赋值语句的左侧，其中指定的部分（右侧）具有类型很长会做。



干杯！

This is from the MSDN documentation: http://msdn.microsoft.com/en-us/library/vstudio/s5b150wd%28v=vs.100%29.aspx[^]

'RFX_Long' : cannot convert parameter 3 from 'CString' to 'long &'

So what does this mean then? You obviously passed a parameter ( the third one) to RFX_Long and what you passed was of type CString, but a reference to a long was expexted plus there is no conversion possible from a CString to a reference to a long.

What exactly is a reference to a long?
Any legal expression allowed as the lefthand side of an assignment statement where the assigned part (righthand side) has the type long will do.

Cheers!
