CString转LPTSTR的问题？

[dkwang]

以下程序是可以的：
char strServerName[ 256 ];
HKEY hKey;
FILETIME FileTime;
DWORD dwData, dwIndex=0;
LONG lResult;

lResult = RegEnumKeyEx( hKey, dwIndex,( LPTSTR )&strServerName, &dwData, NULL, NULL, NULL, &FileTime );
如何使下面的代码成功：

CString strServerName;
HKEY hKey;
FILETIME FileTime;
DWORD dwData, dwIndex=0;
LONG lResult;

lResult = RegEnumKeyEx( hKey, dwIndex, ????????????//( LPTSTR )&strServerName, &dwData, NULL, NULL, NULL, &FileTime );

应该是这样的：
以下程序是可以的：
char strServerName[ 256 ];
HKEY hKey;
FILETIME FileTime;
DWORD dwData, dwIndex=0;
LONG lResult;

lResult = RegEnumKeyEx( hKey, dwIndex, strServerName, &dwData, NULL, NULL, NULL, &FileTime );
如何使下面的代码成功：

CString strServerName;
HKEY hKey;
FILETIME FileTime;
DWORD dwData, dwIndex=0;
LONG lResult;

lResult = RegEnumKeyEx( hKey, dwIndex, ????????????//( LPTSTR )&strServerName, &dwData, NULL, NULL, NULL, &FileTime );

(LPTSTR)(LPCTSTR)strServerName

[zyf_1977]

把strServerName变为char型然后再运行RegEnumKeyEx( hKey, dwIndex, ????????????//( LPTSTR )&strServerName, &dwData, NULL, NULL, NULL, &FileTime );就可以了

(LPTSTR)(LPCTSTR)strServerName
不行阿？！

[guostong]

(LPTSTR)strServerName.GetBuffer(100);

泳完后 strServerName.releasebuffer();

[老码不惑]

sorry，每仔细看。可以这样：
... = RegEnumKeyEx(..., strServerName.GetBuffer(128),...);
strServerName.ReleaseBuffer();

同意笨驴的说法(据双手赞成！)
还可以用CString.GetBufferSetLength(CString.GetLength());
再CString.ReleaseBuffer().

[neomeng]

简单。用(LPTSTR)CString.GetBuffer(CString.GetLength());

[dkwang]

还是不行！

不可能把，我就是这样作的
