When I try to databind my comboBox (specifically field "emplcode") to a
filled dataset , the contents of the comboBox displays a bunch of
"System.Data.DataRowView". I assume the amount of times
"System.Data.DataR..." is displayed inside the combobox is the amount of
records in the dataset. On the other hand, if my query is "select emplcode
from payemployee", the databind will work fine (but I don't want to limit
the dataset to one field)....

I have 2 bound ComboBoxes. I want the datasource of the second to be limited
by the selection made in the first. I can do this by responding to the
SelectionIndexChanged event on the first, but this results in the
BindingContext's Current.Row.Rowstate becoming 'Modified' whenever the
BindingContext position changes. What is the RIGHT way to go about this?
Thanks,

ComboBox databindng Problem
== How the ComboBox is setup and used:
My comboBox is populated by a lookup table. The ValueMember is the
lookup table's Id and the DisplayMember is the text from a
corresponding field in the lookup table. In my data table we store the
ID in what I will call the 'key' field.
== Description of the desired operation:

Hi Everyone,
I am at my wit's end here. I have a combobox (combyQueryTitle) that I
need to use in order to select a query for my database project. Therefore,
I am using the comboQueryTitle_SelectedIndexChanged handler to, when a new
selection is made, update the query and refresh the display. The only
problem is that the program seems to inexplicably start with the
..selectedindex property at -1! This makes no sense to me. ...

I've been reading all the help I can on the topic (MSDN, other) but I
can't make sense of this.
Desired behavior;
The user is to choose from the displayed list of the databound combobox
and the coresponding 'Id' from the lookup table is to be inserted into
the field of the new record.
I have two simple tables. "tblPerson" is the data table. The lookup

I have a combobox that is very much like the one found in the RSS
project here:
http://msdn.microsoft.com/vstudio/express/visualCSharp/learning/
My projectNameComboBox basically is filled with a list of values from a
table, and as the user selects values, a datagrid displays related
records from another table because it is bound via FK relationship.
My table:
/****** Object: Table . Script Date: 06/19/2006

I'm using a ComboBox to display objects of a class I've defined, say CQQ.
Works great except somehow I occasionally set an Item to a String object
instead of an object of type CQQ.
It looks like Text replaces an item or something like that.
This results in a runtime error at which time I learn that the item that
should be CQQ is a String.

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 folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

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,...
