Update IIS Bindings?
Feb 15, 2011I have a list of sites that I need to update their bindings from the current IP address listed to another one, how can I possibly do that using VB.NET? I will have to do this often and I don't want to manually update that every time.
View 1 RepliesHow To Change Key Bindings Programatically
Dec 11, 2010I'll try to make this simple, using VB.Net on Windows Vista:How do you change key bindings programatically?I'm thinking it has to do with the registry so if it does just give me the registry key names(i know how to change the registry already)If it helps, the reason I want to do this is to change the Windows media center button so that it opens my program rather than WMC.

Jul 23, 2010I'm trying to set up an installer to register a web site. Currently, I've got it creating an Application Pool and Web Site under Windows Server 2003. Unfortunately, whenever I try to modify the ServerBindings property to set the IP Address, it throws an exception at me. I first tried this because the documentation here told me to [URL]. I'm currently using VB.NET, but C# answers are okay too as I need to switch it over to using C# anyway.

Difference Between Early And Late Bindings?
Oct 28, 2009Difference between Early and Late Bindings.
Example of Late Binding:
If
sender IsNot Nothing AndAlso TypeOf sender Is Values Then
receiveobj = CType(sender, System.Object)
a1 = CType(receiveobj.a1, Int32)
End If
How do I change this into the prefered Early Binding?

C# - Dependency Property Bindings Not Working For Class

Data Bindings Not Updating When New Record Selected
Feb 26, 2009This is the form I'm having problems with. As you can see I've created a tab interface which is working. There are five text boxes on it which are binded to the Staff table in the database. When the tab is changed, the binding is changed to a new field. However, unfortunately, when a new record is selected, the data bindings do not update, and instead, the first record is always being used. We suspect the problem may be coming from the fact that there is code to unbind from the text box and rebind it again. This is the code I'm talking about...
Private Sub TabCheck()
If TabState = 1 Then
pnlTabs.BackgroundImage = My.Resources.tabs1
txtBox1.Visible = True
txtBox2.Visible = True

DataBinding Cannot Find A Row In The List That Is Suitable For All Bindings
Aug 6, 2008I have a GridView and some textboxes, etc whose BindingSource is a list of business objects.
Problem comes when my business objects are updated programmatically. My objects implement INotifyPropertyChanged, and I raise the PropertyChanged event when the object is updated. When the object changed happens to be the selected row in the GridView.
I get the following exception: System.InvalidOperationException
DataBinding cannot find a row in the list that is suitable for all bindings.
How can I solve this?

VS 2010 Multiple Control Property Bindings
Oct 28, 2010I am having difficulty getting some form control property bindings to work correctly. Below is the code I am using-
[Code]...
The ZedGraphControl is just a GraphPane, and the TolSelectBtn is just a button. Problem is, the ZedGraph control binding works properly, but the binding to the button does not (both controls' Visible properties are set to False in the design window). Can a ToolStripMenuItem only handle one data binding? Or is there something else I should be looking for?
Access Database - Setting All Bindings And Table Adapters
Feb 24, 2009 I have a project that I used the 'Connect to Database' tool to set all the bindings and table adapters, etc. Currently the database is housed in the same directory as the exe. I was asked if I could have the database location be a dynamic value. My question is when you set up a project to work with a database using the 'Connect to Database' tool, how can you change its location?
I found this setting:
ASRDBConnectionString
But its read only.
Within that setting is text that says: DataDirectory
So thought that might be a variable to change somewhere....but can't find it.
DateTimePicker Losses Data Bindings On Changing Date?
Feb 9, 2010I have a form with a datagridview, 2 datetimepicker(dtp) controls, combobox, textbox, 3 buttons and a bindingsource. All my controls are bound to the datasource and seem to work fine when the form loads. One of my datetimepicker controls losses the bindings when I add a new row to the datagridview and save the changes. I validate the date entered in this dtp.

VS 2010 Data Bindings - Invalid Cast Exception With DBNulls
Sep 8, 2011I'm binding a ComboBox's SelectedIndex to a Nullable database field like so:
VB.NET
ColapsoComboBox.DataBindings.Add("SelectedIndex", EnsaiosBindingSource, "Colapso", False, DataSourceUpdateMode.OnValidation, 0)
As you can see, I've defined the NullValue to be zero, yet I get an InvalidCastException. Is there anything I'm doing wrong? Or is handling the binding's Format and Parse events the only way around this?
Databinding In WPF Be Done Simply With A Dataview Like In Winforms?
Jun 15, 2012Short and simple question. In Winforms you can bind a dataview to a combobox or some other control by simply:
combobox.DataSource = dataview
combobox.DisplayMember = "Something"
In WPF I've generally done databinding using an ObservableCollection and edits to the xaml. Is there a way to quickly do it, like the above? Edit: This seems to be the simplest/quickest thing I can come up with, anything inherently wrong with it?

VS 2010 Can A Dll Simply Be Updated By Overwriting Old One?=

Can I just give my users a new copy of the .dll or do I have to re-reference it in my project and then compile my programs all over and then give them a new copy of the entire program?
View 5 RepliesBind Combobox To Datatable And Object Property Causing Duplicate Bindings
Aug 19, 2011I'm trying to populate the list of a combobox by binding it to a datatable. Also, I want the selected value of the combobox to be bound to an object property so that when the selected value changes, it's automatically updating the object. However it's causing an error at runtime: "This causes two bindings in the collection to bind to the same property.
Parameter name: binding" I thought binding the dropdown list to a datatable and the selected value to an object were different properties but obviously I'm not getting it right.

With Me.PlanSiteSelect
If _Plan.PlanID <> Nothing And _User.UserID <> Nothing And _Plan.Category <> Nothing Then

C# - Isn't .NET's Integer Just Simply Based On Two's Complement System
May 18, 2012MSDN: Int32 values are represented in 31 bits, with the thirty-second bit used as a sign bit. Positive values are represented by using sign-and-magnitude representation. Negative values are in two's complement representation. Isn't it true that the representation of positive values using sign-and-magnitude system is identical to the representation of positive values using two's complement system? So shouldn't it have been rewritten as: "Int32 values (regardless of positive or negative) are represented in two's complement representation",

I have tested this with some simple dates, but would like some input if this can be done in better ways.This sample assumes a week with 5 business days, monday-friday, where first day of the week is monday.
