I have a webbrowser in the form, ele is a HtmlElement on the page in the browser. now, I want to get ele's value (if it exists). if I turn off option strict, then
If (ele.DomElement.value() IsNot Nothing) Then
val = ele.DomElement.value.ToString.ToLower()
End If
this works. but if I turn on option strict, then it has error for "disallow late binding".
I guess I should use ctype to convert ele.domElement, but what type should I convert it to? htmlelement will not work.
I have strongly typed code which throws a Late binding Disallowed due to Strict On exception. Is there a way to allow late binding, without turning my stict option to off?
I am trying to get some code to compile after switching Option Strict On. However I am using some Interop with VB6 and passing in a form object ByRef so Form.Caption fails and I can't convert it to type Form because a VB.NET Form doesn't have a caption property.
How can I can get the following to compile with Option Strict ON:
Public Sub EditFormLegacy(ByRef objForm As Object) objForm.Caption = objForm.Caption + " Edited" End Sub
Is there any way to switch option strict off for specific methods?
I am new to VB .NET I am having an error:Option strict on disallows late binding, when I execute my script. So I turned off the "option strict off" then I got the error: cannot create activex component, at microsoft.visualbasic.interaction.createobject(string progId,string serverName) what is wrong in this code.
How do I code this routine to work with Option Strict On? I understand it is a late binding problem but I don't know enough about how to correct.
Code: Dim parms As String = "" For Each chk In Me.GroupBox1.Controls If TypeOf chk Is CheckBox Then If chk.Checked Then parms &= chk.Tag.ToString & " " End If End If Next
I am migrating VB 6.0 code to C#.Net via VB.NET. To prevents typr conversion errors, Option Strict needs to be on. However this is giving me the error 'Option Strict On Disallows Late Binding' on these follwowing lines of code. The code is to read the Global Address Book and the contacts before sending mail using MAPI.
I've set Options strict On in my project. I've been able to fix most of the code, but am stuck on on: cboCity.SelectedValue = cboFacility.SelectedItem("city_id") This worked fine until I set the option. Is there a better way to do this?
I have seen numerous errors with this, but I am a bit confused. I am taking a vb.net class now, and we are learning that Option Explicit is definately the way to go in all projects to make sure you follow some coding standards and to deviate from sloppyness.
Anywho, could someone explain what late binding actually is? I have seen a few definations of it, but nothing really makes sence. I know that you have both Early and Late Bindings, and from what I can understand, it is where you reference what you will be using in your project (as in references?)
I'm converting one of my projects with Option Strict On, but I get a failure which I can't seem to solve.
Option Strict On doesn't allow late binding:I'm loading a combobox with a particular field from a .sdf. When I select a value from the combobox it loads other values from the sdf, but I get the error when Option strict on.
I am working with another programmer's code. Had it been my code from scratch, option strict on would've been set. But it wasn't. So I turned it on and I have 46 errors. That doesn't bother me as they're usually simple issues but I do not understand late binding What is wrong with this code?

I'm using a flow layout panel, with picture boxes inside. Using the code "AddHandler Picture.DoubleClick, AddressOf PictureClick" I wanted to open the picture in the program the computer uses. This is because my program shrinks the picture to 400x400.The problem I'm having is getting to the path to start the program. I tried setting Picturebox.tag to the path, but I got Option Strict Disallows Late Binding error. I know this is because a handler requires "ByVal sender As Object" and I need to tell it that I'm using a picturebox, but I cannot without stopping the handler from working.
I like to keep Option Strict On, but in some cases I need late binding.
For example I need to read the value of Geometry.Area when Geometry could be either a Square or a Circle.
It is not my object model, and Square and Circle are not derived nor share an interface that implements the Area property, so I need either a huge Select Case for each geometry type and for each property, or I use late binding.
I tried with this and a few similar variants, but I couldn't get it to work:
Geometry.[GetType]().InvokeMember("Area", Reflection.BindingFlags.GetProperty Or Reflection.BindingFlags.Public Or Reflection.BindingFlags.Instance, Nothing, Geometry, Nothing)
I have this declared up top. Public oldDocument As mshtml.IHTMLDocument And this function. Public Function GetFocusedElement() As mshtml.IHTMLElement Dim focusedElement As mshtml.IHTMLElement = Nothing [Code] ..... On the "OldDocument" lines, I get the error "option strict disallows late binding" when I have Option strict on.
I have to take over a project written in vb.net, which contains more than 400k lines of code written in option strict off mode. I want to build it under option strict on first before I do anything else -- which maybe converting it into C#. I found there's thousands of lines of code raises compilation error, mostly are about implicit type casts. Is there any tool would help to make it compile under option strict on mode if I don't want to correct every single line manually? Because it's really painful to add CStr/CInt invocation into every line of Code myself.
