Windows API编程问题
以下代码来自与《精通Windows API》 ，用于遍历驱动器并获取驱动器属性
但是在vs2008下不能编译通过，问题如下：
1>d:\my documents\visual studio 2008\projects\api4\api4.cpp(48) : error C2664: 'GetDirverInfo' : cannot convert parameter 1 from 'TCHAR [260]' to 'LPSTR'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
1>d:\my documents\visual studio 2008\projects\api4\api4.cpp(56) : error C2664: 'GetDirverInfo' : cannot convert parameter 1 from 'TCHAR [260]' to 'LPSTR'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
1>d:\my documents\visual studio 2008\projects\api4\api4.cpp(82) : error C2664: 'GetDriveTypeW' : cannot convert parameter 1 from 'LPSTR' to 'LPCWSTR'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
1>d:\my documents\visual studio 2008\projects\api4\api4.cpp(118) : error C2664: 'GetVolumeInformationW' : cannot convert parameter 1 from 'LPSTR' to 'LPCWSTR'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
1>d:\my documents\visual studio 2008\projects\api4\api4.cpp(122) : error C2664: 'lstrlenW' : cannot convert parameter 1 from 'CHAR [260]' to 'LPCWSTR'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
我对代码中各个函数之间的参数做了Unicode与ANSI变换，程序依旧无法得到准确结果。还请高手指点。
源代码如下：
#include <stdafx.h>
/* 头文件 */
#include <windows.h>
#include <stdio.h>
/* 预定义 */
#define BUFSIZE MAX_PATH
/* 函数申明 */
BOOL GetDirverInfo(LPSTR szDrive);

/*

LPTSTR = _TCHAR *
LPCTSTR = const _TCHAR *
*/
int main(void)
{
TCHAR buf[BUFSIZE]; // 卷标信息
HANDLE hVol; // 卷遍历句柄
BOOL bFlag;
hVol = FindFirstVolume (buf, BUFSIZE );
if (hVol == INVALID_HANDLE_VALUE)
{

return (-1);

GetDirverInfo (buf);
while( FindNextVolume(
hVol,

{
GetDirverInfo (buf);

return (bFlag);
}

[解决办法]
什么都不动，只在项目属性里面调整字符集
