At a guess I would say that the ActionState of the MiDocView control is set to a value that is no longer valid under Office 2007.

Open Form1 in design mode and select the axMiDocView1 control, then look at the properties for the control, under Misc there is a property called ActionState, set this to a different value and see what happens. You may need to remove and readd the reference to the MODI ocx control as well.

For each and every active x control, it is needed to create it first, so that all the events and handles should be initialized.

Use axMiDocView1.CreateControl()

Hi,
I am using AxMSTSCLib.AxMsTscAxNotSafeForScripting activex component for open RemoteDesktop on a windows forms code is given below

Dim RDP As New AxMSTSCLib.AxMsTscAxNotSafeForScripting
RDP.CreateControl()
RDP.Server = "Servername"
RDP.UserName = "user"
Dim s As IMsRdpClientNonScriptable = DirectCast(RDP.GetOcx(), IMsTscNonScriptable)
s.ClearTextPassword = "PWD"
RDP.Connect()

code works fine but when i run the program the control is not visible.

How to fix this??
