/// Creates a bitmap from the supplied ActiveX control using OleDraw

An example of this that I have encountered is using the FarPoint Spread 3.0/6.0 ActiveX controls. These controls will throw a Runtime protected memory violation exception if they are hosted in a WinForms Form, instantiated and then the Form.MDIParent property is set to an MDI container Form but using the SetParent(childForm.Handle, Me.Handle) call works.

        FEATURE_RESTRICT_ACTIVEXINSTALL = 10,

    SBSP_TRUSTEDFORACTIVEX = 0x10000000,

interface ActiveX {

Interface ActiveX

This sample uses IInternetSecurityManager within an ActiveX control to determine the Zone from which the web page hosting the control is loaded. If the Zone is not My Computer, a flag is thrown indicating the zone is not safe. This is useful for cases where you want to mark a control as safe for scripting, but you want to limit the zones in which it is allowed to run or to perform certain actions, something IE security does not allow. Note that you will need to add shdocvw.dll as a reference within your project, and that you should set "Register for COM Interop" to True in Project Properties | Configuration Properties | Build.

I haven't been able to get this to work at all in JavaScript unless the ActiveX control in is object tags.

So, even if your ActiveX control doesn't have any UI, don't do this:

  MyObject = new ActiveXObject("IEZoneSecurity.ZoneSecurityDemo");

    ActiveXScriptletRun = unchecked((int)0x00001209),

    DownloadUnsignedActiveX = unchecked((int)0x00001004)

    ActiveXScriptletRun = 4617

    DownloadUnsignedActiveX = 4100

            //Get a IOLECommandTarget object form the ActiveX control

        axWebBrowser = (SHDocVw.IWebBrowser2)webBrowser.ActiveXInstance;

// Get the ActiveX interface of some window of class "Internet Explorer_Server"

        //        [in]    LayoutDesign.CtlLayout (ActiveX control)

        // An ActiveX control returns a handle to a LOGFONT in unmanaged global mem.

        //        [out]    LayoutDesign.CtlLayout (ActiveX control)

        // Use the ActiveX's global memory.

        // Update the ActiveX control.
