help needed!!

[Shum]

Hi all!!! I found this piece of code from one of the threads here, I too want to get the list of tables and data types of columns, but when i tried to use this code in my program it gives me error:
"WindowsApplica tion2\Form1.cs( 202): The type or namespace name 'TableInfo' could not be found (are you missing a using directive or an assembly reference?)"

and similar errors for m_oleDbSrcConn and table info obj... which namespaces do u think are needed?? what else could be the problem..

private void GetTableInfo()
{
DataRowView drvCols = null;
DataTable dtCols = null;
DataView dvColumns = null;
TableInfo tabInfoObj = null;
string sTableNm = null;
string sNamePrefix = null;
string sColName = null;
int nColType = 0;
 
// Get the list of tables that there are.
DataTable schemaTab =
m_oleDbSrcConn.GetOleDbSchemaTable(OleDbSchemaGuid .Tables,
new Object[] {null, null, null, "TABLE"});
 
for (int i = 0; i < schemaTab.Rows.Count; i++)
{
sTableNm = schemaTab.Rows[i].ItemArray[2].ToString();
sNamePrefix = sTableNm.Substring(0, 4);
 
if ((sTableNm != "_NEW_TABLES") && (sNamePrefix != "temp"))
{
tabInfoObj = new TableInfo(sTableNm);
 
// Get the column name and its type and sort them
// according to their position in the table.
dtCols = m_oleDbSrcConn.GetOleDbSchemaTable(
OleDbSchemaGuid.Columns,
new Object[]{null,null, sTableNm, null});
dvColumns = new DataView(dtCols);
dvColumns.Sort = "ORDINAL_POSITION";
 
// Get the column names and their types.
for (int j=0; j< dvColumns.Count; j++)
{
// Get the name of the column.
drvCols = dvColumns[j];
sColName = drvCols.Row.ItemArray[3].ToString();
 
// Get columns data type code and save it off.
nColType = Convert.ToInt32(drvCols.Row.ItemArray[11]);
tabInfoObj.AddColumn(sColName, nColType);
m_alTables.Add(tabInfoObj);
}
} // if
 
} // for
}
