WebBrowser Application Error

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi 

I am receiving an application error when hosting a WebBrowser control within a VB ActiveX control and using the SetObjectForScripting (if you remove it there is no error).

I guess it is a problem with the clean up when the control is destoyed (it happens on exit of the .exe or VB itself in design time).

I am hosting your control in another because I extensively use the MSHTML functionality for HTML editing but also need the ability for HTML to call functionality within the application.

Any thoughts?

David

	uploads/20080414_042921_codejock.zip Hi Attached is a sample of both control and app in the most basic form possible. If you build and register the control and then build the app, the error occurs when closing the .exe. (Environment: VB6 (SP5) Extreme 11.2.2 / Windows 2000 (SP4) or XP) Thank you David (Can only assume it's to do with binding the function on the control rather than a form)

	Thanks. Ye, problem that need to release ObjectForScripting. You can add public method and call it from container: Public Sub BeforeUnload() WebBrowser1.SetObjectForScripting Nothing End Sub .... Private Sub Form_Unload(Cancel As Integer) UserControl11.BeforeUnload End Sub

	Hi we are having a similar problem but we cannot get the scripting errors to stop by using webbrowser.setobjectForscripting. We have the webbrowser control inside of our application. below is the snippet of where we are calling it. When we set the setobjectforscripting... it still comes back with scripting errors Private Sub Form_Load() On Error GoTo handle_error Screen.MousePointer = vbHourglass sDefaultPage = "http://intranet.woodloch.com/roomready" Me.web.Navigate sDefaultPage Me.web.setObjectForScripting Me bFrmLoaded = True GoTo doneSub handle_error: bFrmLoaded = False Call objErrHandler.HandleError(Err.Number, Me.Name & ".Form_Load", Err.Description) doneSub: Screen.MousePointer = vbDefault End Sub

	Hi You can stop the standard script warnings by simply adding: WebBrowser1.ScriptErrorsSuppressed = True However it does require the 'Disable script debugging' in the advanced settings of IE to be checked, otherwise you get a debug error.
