本文介绍一种通过ADO列举Access文件中所用用户表和表信息的方法，仅供参考，源代码在VC6.0＋XP环境通过测试。
首先，需要引入msado15.dll文件，在stdafx.h中添加：
#import "c:\program files\commonfiles\system\ado\msado15.dll" no_namespacerename("EOF","adoEOF")
其次，将下面的代码复制到cpp文件中：

{
int nRetCode = 0;
//初始化com环境
CoInitialize(NULL);
GetDatabaseInfo("c:\\test.mdb");
CoUninitialize();
return nRetCode;
}
void GetTableInfo(_ConnectionPtr& pConnection, CStringstrTableName)
{
_variant_t recAffected;

{
int nCount = 0;
//开始打开表，以便得到表的结构
_RecordsetPtrpRecordset;
pRecordset.CreateInstance(__uuidof(Recordset));
pRecordset->Open((LPCTSTR)strTableName, pConnection.GetInterfacePtr()
, adOpenDynamic, adLockOptimistic, adCmdTable);
FieldsPtr fds =pRecordset->GetFields();
//依次读取字段，并显示
//字段名
for(int i = 0; i <fds->GetCount(); i++)
{
FieldPtr fd= fds->GetItem(_variant_t(short(i)));
if(fd->Value.vt != NULL)
{
CString strName((LPCTSTR)fd->GetName());
printf("字段%i,名称%s,类型%s,长度%ld
\r\n",i+1
, (LPCTSTR)fd->GetName(), GetType(fd->GetType())

}

}
}
编译运行，可以打印Access数据库的信息，一个例子如下：
view plaincopy to clipboardprint?
查到一个表：Result
字段1,名称ResultID,类型Integer,长度4
字段2,名称TaskID,类型Integer,长度4
字段3,名称TestTime,类型Integer,长度4
字段4,名称DestIP,类型VarWChar,长度255
字段5,名称TestType,类型Integer,长度4
字段6,名称AvgDelay,类型Integer,长度4
字段7,名称MinDelay,类型Integer,长度4
字段8,名称MaxDelay,类型Integer,长度4
字段9,名称IPAvailability,类型Integer,长度4
字段10,名称IPDV,类型Double,长度8
字段11,名称LossRate,类型Double,长度8
查到一个表：ResultData
字段1,名称ResultDataID,类型Integer,长度4
字段2,名称ResultID,类型Integer,长度4
字段3,名称ElapsedTime,类型Integer,长度4
字段4,名称PacketSize,类型Integer,长度4
字段5,名称ResultType,类型Integer,长度4
字段6,名称Delay,类型Integer,长度4
字段7,名称ErrorInfo,类型VarWChar,长度255
