Question

CString转换成const char*的问题

CString strAviFilePath="D:/car.avi";
//定义如下一个函数
const char* filename =strAviFilePath;//这条语句如何正确赋值
即是：如何将CString转换成const char*,strAviFilePath的值如何赋给filename,希望求助于高手，最好写明如何赋值的语句，在线等待中，不胜感激！
我用的编程环境是vc2005

Answer 1

CString类里面有一个成员函数
CString::GetBuffer
LPTSTR GetBuffer( int nMinBufLength );
throw( CMemoryException );

Return Value

An LPTSTR pointer to the object’s (null-terminated) character buffer.

Parameters

nMinBufLength

The minimum size of the character buffer in characters. This value does not include space for a null terminator.

于是乎 就可以这样
const char* filename =strAviFilePath.GetBuffer(sizeof(strAviFilePath));
