I 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 RepliesI'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.
View 3 RepliesI'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.
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?
Can I use VB.Net's generics to simply Wpf notifiable bound controls?
View 1 RepliesI want to update the date and time from two separate pickers to my table.My 2 DTPers are bound to a dataset.One is in the Short Format, the other is Time.I have several other bound controls, and I just do a .Update to update my table. I tried just updating the row:
Me.DsTradeShow1.Tables("Tradeshow_Details").Rows(0).Item("Show_Date") = CDate(Me.DateTimePicker15.Text & " " & Me.DateTimePicker16.Text)

I have a custom class and my dependency properties won't work with bindings unless I declare the class as a static resource.

This 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

I 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?

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?
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.
I 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.

I'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?
I'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.

I am using an update panel and when I click a button it will update all the panels. updapanel1.update() is very simple, but my data is not updating unless I hit the button twice. My gridviews shows data for a selected user, and then all the grids reflect that users data. works fine all the update panels work for the gridviews.
