I have a lot of respect for David Fenton and Allen Browne, but I don't
understand why people who know how to write code to completely replace
a front end do not write something that will automate the code that
implements managing unbound controls on forms given the superior
performance of unbound controls in a client/server environment. I can...

Hi,
I'm having trouble getting control data binding to work. As I understand
it, the simplest form of databinding requires three things:
1) A control (say a textbox) on a form or user control,
2) A field or object.member to which you want to bind,
3) A "Binding" object that connects the variable to a property of the
control ("Text"...

I have a WinForm with controls bound to a typed recordset that was generated
by the Dataset Designer. There are several ComboBox controls with their

except when I need to handle a null default value in the data record coming
from the database. I want the combo whose...

I am used to VB6 but need to develop something in .Net.
I need to create several bound combo-boxes which will use lookup tables to
get their values.
I created a form using the dataform wizard. As part of the setup, I
specified a new dataset, which included the data & lookup tables. I also
specified the relationships when required.

I have a number of TextBox controls bound to date fields in my

entering data into the bound field, if you enter any string that cannot
be converted by the system into the date/time format, the application
will not allow you to leave the TextBox control, even to close the...

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...

Can I use a bound ComboBox for both browsing and editing?
I'm working on a small, standalone database application using Visual
C#.NET 2003 and an Access data file.
In order to keep the number of different screens down to a minimum,
I'm trying to use the same Windows Forms for both browsing and for
updating. This works fine for TextBoxes,...

Is there a way that a bound ddl control can:
1. display the bound data, even if it does not match a selection in
the DDL?
2. allow the user to enter something other than the look up values?
I have a bound dropdown list that retrieves it's selections from a
look-up table. The DDL is bound to a database table and unless the
value in the...

I have a databound dropdownlist control. Based on some other criteria, I
need to specify the selected item in my pages Load event.
The problem is that, in my load event, the control does not yet have any
data. I've found I can call DataBind() on that control and then it works
okay. However, this has me wondering where the control normally...

So here's the situation (.NET 2.0 btw):
I have a form, and on this form is a textbox among many other
databound controls. The textbox is bound to a field in a data table
via the Text property. In this table there are multiple columns that
cannot be NULL, which, are bound to other controls (but they're not
really important at this time).

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. ...
