[英]How to restore drive mount after DeleteVolumeMountPoint?
After using DeleteVolumeMountPoint("E:\\") (for instance) in order to delete the mounting point of a DOK, i would like to restore it.在使用 DeleteVolumeMountPoint("E:\\") (例如)以删除 DOK 的安装点后,我想恢复它。 (make the drive letter usable again) (使驱动器号再次可用)
How would I do that?我该怎么做?
Looking at the MSDN documentation for DeleteVolumeMountPoint says that SetVolumeMountPoint would do the task.查看DeleteVolumeMountPoint的 MSDN 文档说SetVolumeMountPoint可以完成任务。
The documentation links to an example :文档链接到一个例子:
#define _WIN32_WINNT 0x0501
#include <windows.h>
#include <tchar.h>
#include <stdio.h>
#define BUFSIZE MAX_PATH
int _tmain( int argc, TCHAR *argv[] )
{
BOOL bFlag;
TCHAR Buf[BUFSIZE]; // temporary buffer for volume name
if( argc != 3 )
{
_tprintf( TEXT("Usage: %s <mount_point> <volume>\n"), argv[0] );
_tprintf( TEXT("For example, \"%s c:\\mnt\\fdrive\\ f:\\\"\n"), argv[0]);
return( -1 );
}
// We should do some error checking on the inputs. Make sure there
// are colons and backslashes in the right places, and so on
bFlag = GetVolumeNameForVolumeMountPoint(
argv[2], // input volume mount point or directory
Buf, // output volume name buffer
BUFSIZE // size of volume name buffer
);
if (bFlag != TRUE)
{
_tprintf( TEXT("Retrieving volume name for %s failed.\n"), argv[2] );
return (-2);
}
_tprintf( TEXT("Volume name of %s is %s\n"), argv[2], Buf );
bFlag = SetVolumeMountPoint(
argv[1], // mount point
Buf // volume to be mounted
);
if (!bFlag)
_tprintf (TEXT("Attempt to mount %s at %s failed.\n"), argv[2], argv[1]);
return (bFlag);
}
只需以交互方式执行此操作,您可以打开“卷管理器”,右键单击卷并分配驱动器号。
