I need to connect to a .dbf
file in visual Studio using C# and populate a data table. Any ideas? I can currently view the tables in Visual Fox Pro 9.0
Code I have tried and failed, keep getting
External table is not in the expected format.
private OleDbConnection conn;
private OleDbCommand cmd;
private OleDbDataReader dr;
private string sqlStr = "";
private DataSet myDataSet;
private OleDbDataAdapter myAdapter;
void test2()
{
conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Users\\PC1\Documents\\Visual FoxPro Projects\\;Extended Properties=DBASE IV;");
conn.Open();
sqlStr = "Select * from Clients.dbf";
//Make a DataSet object
myDataSet = new DataSet();
//Using the OleDbDataAdapter execute the query
myAdapter = new OleDbDataAdapter(sqlStr, conn);
//Build the Update and Delete SQL Statements
OleDbCommandBuilder myBuilder = new OleDbCommandBuilder(myAdapter);
//Fill the DataSet with the Table 'bookstock'
myAdapter.Fill(myDataSet, "somename");
// Get a FileStream object
FileStream myFs = new FileStream
("myXmlData.xml", FileMode.OpenOrCreate, FileAccess.Write);
// Use the WriteXml method of DataSet object to write XML file from the DataSet
// myDs.WriteXml(myFs);
myFs.Close();
conn.Close();
}
This code worked for me!
public DataTable GetYourData()
{
DataTable YourResultSet = new DataTable();
OleDbConnection yourConnectionHandler = new OleDbConnection(
@"Provider=VFPOLEDB.1;Data Source=C:\Users\PC1\Documents\Visual FoxPro Projects\");
// if including the full dbc (database container) reference, just tack that on
// OleDbConnection yourConnectionHandler = new OleDbConnection(
// "Provider=VFPOLEDB.1;Data Source=C:\\SomePath\\NameOfYour.dbc;" );
// Open the connection, and if open successfully, you can try to query it
yourConnectionHandler.Open();
if (yourConnectionHandler.State == ConnectionState.Open)
{
string mySQL = "select * from CLIENTS"; // dbf table name
OleDbCommand MyQuery = new OleDbCommand(mySQL, yourConnectionHandler);
OleDbDataAdapter DA = new OleDbDataAdapter(MyQuery);
DA.Fill(YourResultSet);
yourConnectionHandler.Close();
}
return YourResultSet;
}
