I am trying to sink an Access.CommandButton Click Event in Vb.NET. I have tried about every technique unsuccessfully. I get the following error: An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in interop.access.dll Additional information: Exception from HRESULT: 0x80040202. My code is as follows: Friend Class clsMain Private oAccApp As New Access.Application Private WithEvents oAccBtn As Access.CommandButton Public Event Fire() Public Sub LaunchAccess() oAccApp.Visible = True oAccApp.OpenCurrentDatabase("C:\Temp\automation.mdb") oAccBtn = oAccApp.Forms("frmMain").Controls("cmdFireEvent") End Sub Private Sub Btn_Click() Handles oAccBtn.Click RaiseEvent Fire() End Sub End Class Has anyone successfully been able to do this? -- AutomationGuru Reynolds Automation Solutions
