VS 2008 - Excel Automation Late / Early Binding
Apr 25, 2011i am having some doubt & problems.
(1) if multiple versions of MS/office is installed in a computer & if i use late binding which version office instance will be rendered by the system.
(2) in the same way if i early binding then which version of office instance will open.
still be more clear i use late binding code. but here how to set the number format of the cell to text.
Office Automation :: Cells Property - Early And Late Binding
Mar 1, 2010I've been aware for some time that the Cells() property is early bound but the Cells.Item() property is late bound. In VBA this all works seamlessly apart from the fact that we lose intellisense in the VBA IDE in the latter case:
Code:
'VBA code
Cells. '<---- we get intellisense
Cells(1). '<---- we do not get intellisense
However, in VB .Net with Option Strict On this means that we have an extra consideration in that we have to explicitly convert to an Excel.Range if we want to set the range reference to a range variable:
Code:
'VB .Net code
Option Strict On
Imports Excel = Microsoft.Office.Interop.Excel
'
'
'
Dim oApp As New Excel.Application
[Code] .....
I'm comfortable enough with this because I'm aware of it and it is trivial to handle by explicitly converting to an Excel.Range. We also had a pretty good discussion about the Cells property a little while back in the VBA board which looked at some of its inner workings. My question is to dig a little bit deeper into the way that this has been implemented. I'm trying to get a better understanding about the reasoning behind the Cells.Item() property returning an Object rather than a Excel.Range?
C# Implement Late Binding For Native Code
Aug 14, 2009We 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?

VS 2008 Option Strict On Disallows Late Binding?
Mar 18, 2009I 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?)

View 19 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]

VS 2008 Does FIND Always Find Within The FILTER Of A Binding Source
Jun 8, 2009I've got a form - CMCConsole It pops up a dialog form for adding a new case.If the matter number in a textbox on that dialog form matches an existing cases matter number I would like to find it in the binding source of the CMCConsole form
Private Function CheckMatter(ByVal MtrNum As String) As Boolean
Dim cfIndex As Integer = CMCConsole.caseBS.Find("MatterNumber", MtrNum)
Dim cfIndex2 As Integer = CMCConsole.casefileBS.Find("MatterNumber", MtrNum)
[code]....
But it appear the filter for the CASE we were just on that is set on the binding source is keeping the FIND from seeing other cases.
caseBS.Filter = "CaseId=" & e.Node.Tag.ToString
Do I have to clear the filter in order to find a matter number in some other case??

View 2 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?
Jul 28, 2010I 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
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?

Asp.net Mvc 3 - Late Binding Issue With MVC3 ViewBag?
Feb 18, 2011I'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.
Hashtable 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?
