Sample Code
The following method populates a ListBox with a RecordSet. Is uses FieldCount to create the header for the ListBox with the names of the columns in the table:
Sub PopulateListBox(dataList As Listbox, rs As RecordSet)
If rs Is Nil Then Return
// set up listbox state for population
dataList.DeleteAllRows
// Add the DB columns as the headers for the ListBox
dataList.ColumnCount = rs.FieldCount
dataList.Column(-1).WidthExpression = "100"
For i As Integer = 0 To rs.FieldCount - 1
dataList.Heading(i) = rs.IdxField(i + 1).Name
Next
// Add the data from the table
While Not rs.EOF
dataList.AddRow("")
For i As Integer = 0 To rs.FieldCount - 1
dataList.Cell(dataList.LastIndex, i) = rs.IdxField(i + 1).StringValue
Next
rs.MoveNext
Wend
End Sub
If rs Is Nil Then Return
// set up listbox state for population
dataList.DeleteAllRows
// Add the DB columns as the headers for the ListBox
dataList.ColumnCount = rs.FieldCount
dataList.Column(-1).WidthExpression = "100"
For i As Integer = 0 To rs.FieldCount - 1
dataList.Heading(i) = rs.IdxField(i + 1).Name
Next
// Add the data from the table
While Not rs.EOF
dataList.AddRow("")
For i As Integer = 0 To rs.FieldCount - 1
dataList.Cell(dataList.LastIndex, i) = rs.IdxField(i + 1).StringValue
Next
rs.MoveNext
Wend
End Sub
