Targeted Version Of The .net Compact Framework Does Not Support Late Binding Warning?
Jun 1, 2010
i am developing a mobile application on visual studio 2008 under .net compact framework for windows ce platform.i use vb.net language i want to add a new row to datatable using Bindingsource object.my code is
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 have a sender as system.object and I want to code textblock1.text=textblock1.text + sender.text sender is the chars(numbers) sent by digitclick of buttons. the problem is this: it doesn't support sender.text and says it's a latebinding and it is not supported by this platform. 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...
How come software created in an older framework version won't run on a newer framework version? Actually whenever i try to run some old specific software having .net 3.5 framework on my PC they show they needs .net framwork 1.1 . What a bad thing?My newer version of Photoshop ans Ms office open all lower version files.
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.
i have this code:Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]...
Error 1: Option Strict On disallows late binding.Im using visual basic 2010 express on a gateway laptop thats running Windows 7 OS How do i resolve this error?
I have a listbox and it it I am showing numbers.It should look like this (line by line) 1,2,3,4,5,6,7,8,9,10,11.....but is is showing it like this 1,10,11,...2,20,21...3,30...ow can I make it that it will show it in number order 1,2,3,4,5......
I'm getting a late binding error message on this specific section of code: objsys.Sessions(shrd.ocSess) Any suggestions as to why I'm getting this late binding error and how to fix it? [Code]
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]
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 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 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 need to create a sound if validation fails. Anyone know how to do that? It can be a wave file or any kind of format.
How can i create a sound in .net compact framework 2.0. using vb.net. I saw codes asking to use system.media class. However in compact framework there do not seem to have this class.
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?
