Hi,
In my application, on some given actions while debugging in Visual Studio, I
suddenly get a "System.ComponentModel.Win32Exception was unhandled"
Message="Error creating window handle." exception.
The problem is that this exception isn't raised somewhere in a method, so it
just shows up, and it causes the application to shut down.
Is there anyway how to catch this kinds of exceptions? Can I put somewhere a

This may seem simple, but I'm having a bit of trouble figuring out
exactly how to do it. I'm accessing a database through an ODBC link,
and I have a query that returns only jobs completed that day (it's
automatically generated). 1 user may finish 10, 20, or 50 jobs a day,
but there can be at least 20-50 users per day, and they're always going
to be different. The users aren't going to return, or if they do, it's
always going to be under...

Dear All,
I have spend a number of hours attempting to find some answers about
how to remove the 3D BorderStyle within a combobox and have come to
the conclusion that the simplest method is to create a user control
and hide the borders using some panels.
This however is not the most efficient method of doing things so I
appeal to those developers who know far more than I. I assume you need
to create a derived class which inherits the...

Hi,
I'm populating a ComboBox with objects which contain two properties -
IntegerValue and StringValue. I display StringValue in the ComboBox
form and can retrieve IntegerValue from the SelectItem.IntegerValue
property. This is all good but now I want to get a little bit more
complicated.
I want to be able to set the ComboBox's SelectedItem property by
setting IntegerValue, so for instance if I have the following items in

If you look at this page on relational database design:
http://r937.com/relational.html
And scroll down to the "Many-to-Many Relationships" Section you will
see a common database structure.
I can not find a simple way to create forms and reports in Access that
allow you to enter and display data in a structure such as this.

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:
