.NET Component - Error When Using Late Binding
Mar 23, 2011Using 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

View 2 RepliesHashtable Value Array (late Binding) Error?
Feb 26, 2011I have a hashtable that stores sports players: key = jersey number, value = an array of information...and what I am trying to do is put this information into combobox (but only showing a certain array elements), so for example say this was the information stored in the hashtable:
(key,{value})
"01",{"john smith","125lbs","qb"}
"02",{"john doe","205lbs","rb"}
so what I have done is created an arraylist that will store the items in the combobox.but my problem happends when I try to loop through the array from the hashtable values.
(playerlisting is the hashtable)
Dim playerlist As New ArrayList
[code]....
The above works, however since it's a foreach loop I cannot specify which array indexes I want to add onto the "listitem" string.
Dim arr As Array = CType(item.Value, Array)
For i = 0 To arr.Length - 1
listitem += arr(i) & " "
Next
But, when I try a simple forloop instead I get a "late binding" error with the 3rd line. Even when I cast the arr(i) as a string I get the error. What needs to be changed?

Is A VB Variable The Equivalent Of An 'instance' In Flash And A VB Object Like A 'symbol' In Flash
Apr 15, 2009Hi, I'm just beginning to teach myself how to do OOP in VB 2008 Express. I have a quick question after seeing a video online.Is a VB variable the equivalent of an 'instance' in Flash and a VB object like a 'symbol' in Flash? Is this what it means by a variable being a reference or pointer to an object and not the object itself?
View 5 RepliesEarly Binding Late Binding
Aug 19, 2009I 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]

View 1 RepliesHow To Move Away From Late-binding Which Use In VBA Project
Aug 14, 2010So 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]

Late Binding And Setting Objects?

Form1:
vb.net

(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
Late Binding Magic Under .NET Converted To C#?
Nov 22, 2011I 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#?

Use Late Binding With Options Strict On
Mar 1, 2012I 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)
Use Option Strict On And Late Binding?
Jun 16, 2011I 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?
