Essentially, InsertAT is broken!
For the past couple of hours, I've been getting this "Parameter name:
'-2147483550' is not a valid value for 'index'." error.
Apparently, its caused by having manually inserted a row in the table
bound to the Combo box. The InsertAt Method of adding a row just does
not work.
Hope this helps anyone with this problem.

Hello,
I have 6 comboboxes, that I thought I could bind to the same datasource, and
have them display different 'selectedvalue's', but apparently I can't...
My code is as follows:
dim drv as datarowview = me.listbox1.selecteditem
dim dtbDL as datatable = _dataset1.Tables(0)
dim dtvDL as new dataview(dtbDL)
dtvDL.RowFilter = "STR_ONE" = 'Matching Text'"

I am using a detail view and binding it to a sql data source (at some
point in the future it will be an object data source).
I have seen the article "Working with Data is ASP.NET 2.0 ::
Customizing the Data Modification Interface", and its description of
how to turn one of the fields into a template field, then add a drop
down list. I want to do the same thing except I want two drop down
lists, with the second one populating its values...

I've come across an interesting bug.
I have workarounds but i'd like to know the root of the problem. I've
stripped it down into a short file and hope someone might have an idea about
what's going on.
It's a simple program that loads a control onto a form and binds "Foo"
against a combobox ("SelectedItem") for it's "Bar" property and a
datetimepicker ("Value") for it's "DateTime" property. The
DateTimePicker.Visible value is set to...

Hello,
I made a windows form with a combo box and 4 text boxes. All 5 objects should get their data from a data set which is populated
in the form load method. The combo box has item ids. When the users selects an item from the combo box I'd like the 4 text boxes to
get populated with the corresponding item information from the same dataset table row that the combo box is pulling it's info from.
Is there an easy way of doing this besides...

Hi folks,
I've got another problem. Basically, I'm trying to use a nested GridView, however the nexted GridView displays no values (even though in debug I'm getting valid values into my DataSet. It's probably a binding issue somewhere, but I'm not sure where.
Here's the ASP (slightly edited to remove verbosity):
<asp:GridView ID="GridViewMain" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#999999"

After having longer discussions about a similar issue, I ask you to
provide an example of the source and destination value(s) and their data
types. Thanks.
Example (of an example):
Source: byte array, content=243 123 45 98 12
Destination: a string containing hex representation of the values,
seperated by blanks: "F3 7B 2D 98 0C"

I am having trouble preventing a bound source from updating using event-driven validation.
There is a very nice article on MSDN explaining this;
http://msdn.microsoft.com/en-us/library/ms229603.aspx
It clearly states, "When you use data binding, the data in your control is synchronized with the data source during execution of the Validating event. If you cancel the Validating event, the data will not be synchronized with the data source."...

Hi,
I have a TabContainer inside a data bound FormView (to logically group the
form fields into different tabs). The display part of the data binding works
fine, but the Update doesn't. Basically the FormView cannot find the
TextBoxes inside the tab container's tab panels. Some of the forums say that
it's because of the TabContainer's implementation (by design) of
"INamingContainer", and a hack is to take control of the TabContainer's...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
