利用ADOX修改ACCESS表字段名（VC/MFC）

//修改ACCESS表字段名
//dbFile:数据库文件名
//tableName:数据库中表名
//oldFieldName:原字段名
//newFieldName:修改后的字段名
BOOL ChangeFieldName(CString dbFile, CString tableName, CString oldFieldName, CString newFieldName)
{
ADOX::_CatalogPtr pCatalog = NULL;
try
{
pCatalog.CreateInstance(__uuidof(ADOX::Catalog));
CString connStr = _T("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=") + dbFile + _T(";");

pCatalog->PutActiveConnection(_bstr_t(connStr));
ADOX::_TablePtr pTable = NULL;
ADOX::_ColumnPtr pColumn = NULL;
pTable.CreateInstance(_T("ADOX.Table"));
pTable->ParentCatalog = pCatalog;
pTable = pCatalog->Tables->GetItem(_bstr_t(tableName));
pColumn = pTable->Columns->GetItem(_bstr_t(oldFieldName));
pColumn->Name = _bstr_t(newFieldName);

pCatalog->Tables->Refresh();  //刷新
}

{
CString errmsg = _T("修改字段名出错:") + CString((LPCSTR)e.Description());
