In my computer excel 2003 is installed. My code runs well in my computer but failed in another computer which only has excel 2007. If I want to make my code still functions in excel 2007, I heard of that something like late binding but I haven't experienced with that and not sure.

I'm trying to make a silverlight app for WP7 using VB and this is my problem. Can I solve it anyway or can I change it with something else with the same action??

I have just installed VS 2010 ultimate onto a desktop running WinXP sp3. When I load/convert my VS2008 projects (based on .Net 2.0) the conversion fails. I get a error message saying that the Targetted Framework is not available. Only .Net 4.0 Framework is available. I have downloaded and installed the .Net 2.0 SDK (as advised), but it still doesn't appear in the available frameworks. I also have VS2008 (Team Studio) installed on the same machine and that can see 2.0, 3.0 and 3.5 .Net frameworks no problems...

I started programming in VBA, then graduated to VB6, and I am now using VB.NET 2008 Express.I have read, in the various posts, that I should keep Option Explicit and Option Strict both on, in order that I use correct VB.NET code and not VB6.I am trying to do that but am totally confused with the results of one of my programmes that was running perfectly with Option Strict off, but now advises:Option Strict On disallows late binding. To me it appears that I am using early binding, but to be honest I am not clear on the binding situation. I have checked through a number of google items, and a number of this Forum's items without seeing the light.[code]

Is there any way to make my programs use a lower version of net.framework other than the newest version 4 that comes with VS2010?I use my programs within a closed network and there isn't an easy way for me to install any software since I'm not the administrator.

Using Visual Studio 2008 I've built a COM object that targets the .Net Framework 2.0.
I'm trying to use the component in MS Access 2007 on XP SP3. If I use early binding it works flawlessly. If I use late binding I get this error:
Run-time error '429': ActiveX component can't create object
Here's my code:
Dim objTest as Object
Set objTest = CreateObject("MyComNameSpace.MyComClass") 'Error occurs here

So I am taking a stab at converting a large VBA project I'm working into .NET. It's in VBA right now only because of convenience of a database (MS Access). But having stumbled upon VB 2010 Express, I'm seeing what I can do in .NET to make my project even better.To that end, one trick I am doing in the VBA project involves late binding.[code]To provide a simplified example, lets say I have three classes, clsOne, clsTwo, and clsThree. They are themselves similar, and in .NET, I'm actually reducing the code each has due to proper class inheritance. But I need to understand how to move away from late-binding, which I use in the VBA project.Now reading into VB .NET some, I've come across the 'Of' keyword, and this looks like the holy grail that I've been seeking. Please understand that these example is not actual code, and the issue cannot be solved (as far as I know) by fancy inheritance and overloading/overriding.[code]

The question is intended for lazy VB programmers. In vb I can do and I won't get any errors.

I have a class from where I need to set objects in another form?
Form1:
vb.net
Function SetMyObject(ByVal frmTarget As Object)
frmTarget.PictureBox1 = Form1.PictureBox1
End Function
(Not tested code, just wrote to show what I mean)So that's the late binding one.I should also say that the frmTarget variable isn't static so thats why I can't make something like Form2.PictureBox1 = Form1.PictureBox1

I should convert some code from VB to C#. Given following lines of VB work (I think only because option is not set to strict):
Dim someProp As SomeType
Try
someProp = CType(SomeInstance, Object).SomeProp
' ...
Due to late binding, this code is possible under VB. Of course, following won't work under C#:
SomeType someProp;
try
{
someProp = ((object)SomeInstance).SomeProp;
// ...
How could I formulate something similar under C#?

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 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 have a function where i am opening up an excel doc and spitting some data out to it. I had this working but then needed to make it so that it would work with older versions of excel as well as 2010.
It was suggested on here that i use late binding instead of including the office interop and allow the system select the appropriate version of interop to use.

I'm trying out MVC Scaffolding in a VB.NET MVC3 project and running into an issue with late binding with Option Strict set on (and I want it on).
This works in C#:
public ActionResult Create()
{
ViewBag.PossibleTeams = context.Teams;
[code].....
causes the compiler error Option Strict On disallows late binding. I took a look at the documentation here: [URL] but it wasn't very helpful.
I notice that a new empty application in C# uses the ViewBag in the HomeController but the VB.NET version uses ViewData, so maybe this is a VB.NET limitation.

We are working with an existing native application (most likely written in VB) that loads assemblies and calls methods with "Late Binding." We do NOT have access to its source code. We want to implement this interface in C#, and have the native application call our C# assembly. Is this anything we have to do beyond matching the method names and method signatures to make it work?
