Data Changes not being saved from DataAdapter

[RSH]

I have a simple application that is filling a dataset, importing several
rows, building an Insert Statement, then attempting to commit the changes.
No exceptions are being raised but the data is never saving and I can't
figure out why not.

This is the method that fills the dataset:
public void PopulateDataset(string strSql)

{

try

{

OleDbCommand _ObjCmd = new OleDbCommand(strSql,
(OleDbConnection)Connection);

m_LDataAdapter = new OleDbDataAdapter(_ObjCmd);

if (Connection.State == ConnectionState.Closed)

{

Connection.Open();

}

m_Dataset = new DataSet();

m_LDataAdapter.Fill(m_Dataset, "tbl");

m_DatasetInitialized = true;

BuildInsertCommand();

}

catch (Exception ex)

{

MessageBox.Show(ex.ToString());

}

}

This method imports the row into the dataset:

public void AddRow(DataRow row)

{

if (m_DatasetInitialized == true)

{

m_Dataset.Tables[0].ImportRow(row);

}

}

This Method builds the Insert Command:

private void BuildInsertCommand()

{

if (m_DatasetInitialized == true)

{

OleDbParameter sqlParam;

OleDbCommand sqlUpdateCommand = new OleDbCommand("INSERT INTO [sheet1$]
([Group],[Category],[SearchPhrase],[CaseNumber],[TimeReceived],[SubmittedBy],[ClientNumber],[ClientName],[Status],[DateClosed],[Product],[AssignedToTech],[Detail])
VALUES(@Group,@Category,@SearchPhrase,@CaseNumber, @TimeReceived,@SubmittedBy,@ClientNumber,@ClientNa me,@Status,@DateClosed,@Product,@AssignedToTech,@D etail)",
(OleDbConnection)m_ObjConn);

sqlParam = new OleDbParameter("@Group", OleDbType.VarChar, 100, "Group");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@Category", OleDbType.VarChar, 100,
"Category");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@SearchPhrase", OleDbType.VarChar, 100,
"SearchPhrase");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@SearchPhrase", OleDbType.VarChar, 100,
"SearchPhrase");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@CaseNumber", OleDbType.VarChar, 100,
"CaseNumber");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@TimeReceived", OleDbType.VarChar, 100,
"TimeReceived");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@SubmittedBy", OleDbType.VarChar, 100,
"SubmittedBy");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@ClientNumber", OleDbType.VarChar, 100,
"ClientNumber");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@ClientName", OleDbType.VarChar, 250,
"ClientName");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@Status", OleDbType.VarChar, 250, "Status");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@DateClosed", OleDbType.VarChar, 250,
"DateClosed");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@Product", OleDbType.VarChar, 250,
"Product");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@AssignedToTech", OleDbType.VarChar, 250,
"AssignedToTech");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

sqlParam = new OleDbParameter("@Detail", OleDbType.VarChar, 1250, "Detail");

sqlParam.SourceVersion = DataRowVersion.Original;

sqlUpdateCommand.Parameters.Add(sqlParam);

m_LDataAdapter.InsertCommand = sqlUpdateCommand;

}

}

And this method attempts to save the data:

public void SaveChanges()

{

m_Dataset.AcceptChanges();

m_LDataAdapter.Update(m_Dataset, "tbl");

m_ObjConn.Close();

}

When I run the code in debugger I see the rows that were imported into the
dataset. I see that the insert Command was been added to the data adapter.
What am I missing?

Thanks so much for the help!
