ActiveX

[Adrian]

Hi
What would the equivalent to an ActiveX be in VB.Net?

I need an application that will run as a trusted site and be imbedded in a
browser but have access to a locally installed programs Com objects. It also
need to be complied so I can't use VB or JS script.

Also is there an upgrade for code written in VB6 for a an OCX / ActiveX to
what ever has superseded it or is it start again time!

Thanks

In General, you cannot create ActiveX *controls* with .NET.

J# Browser Controls provide developers with a way to migrate their existing
Java applet source code to run within the context of the .NET Framework

For .NET 1.0, controls as ActiveX are only supported hosted in MS IE 5+6:

Hi

I can't get the VB.Net example to look like or work the one at
http://www.vbdotnetheaven.com/Code/Jun2003/2067.asp

I cannot get the Inherits System.Windows.Forms.UserControl, AxMycontrol line
to enter with out an error! What have I done wrong?

Thanks (and yes I'm new to .Net!)

Below is what it looks like when I enter the code from the above link!



Namespace ActiveXDotNet

Public Interface AxMyControl

Property UserText() As String

End Interface

End Namespace

Public Class myControl

Inherits System.Windows.Forms.UserControl

Private mStr_UserText As String

Public Property UserText() As String

Get

Return mStr_UserText

End Get

Set(ByVal Value As String)

mStr_UserText = Value

txtUserText.Text = Value

End Set

End Property

End Class

OK, it worked without the Inherits System.Windows.Forms.UserControl,AX...
Thanks
