hello to everyone
i am working with vb6 & mapobjects2.4 and also i wrote code for "To select features based on an SQL expression" and i got an error as "Object Variable or With block Variable not set" .i want solution for this this problem

code:

Dim recset As New MapObjects2.Recordset
Dim LabelPlacer As New MapObjects2.LabelPlacer
Dim g_symSelection As MapObjects2.Symbol

Private Sub Form_Load()
Dim r1 As New Rectangle

end sub

If Not recSelection1.EOF Then

End Sub


Private Sub Map1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)

If Button = 1 Then

End If
End Sub

End If
End Sub

Private Sub cmbSel_Click()
If cmbSel.ListIndex = 0 Then
Map1.Visible = True
legend1.setMapSource Map1
legend1.LoadLegend True

End If
End Sub


Advance thanks for giving solution for my problem

Try to register the component with windows using REGSVR32 key before using in project.
