access delete row by date
I have an access file with a datetime column. Apparently access doesn't have
just a date option when creating a column. I would like to create a query in
a dataset to erase all entries for a particular date. However when I say;
DELETE FROM Table WHERE (Date_Downloaded = ?)
nothing is deleted because it's not exact to the second. '12/20/2008
10:30:22 AM' How can I rework my stateme...

LINQ-to-SQL and intersection entities

has been represented as a User class, an Group class, and a UserGroup class
(the intersection). I would prefer to have the relationship modeled as:

Standard Control Locations on a Windows Forms Form
I have a groupbox I am creating programmatically ... I add textbox controls
to the groupbox. There is a user-defined number of rows and columns for
these textboxes so the groupbox grows in height and width (as does the form)

Size of images in image list
Hello,
I have an ImageList that will store a large number of images, but if
it starts using too much memory, I'd like to be able to purge it (or
part of it). The problem is, I'm not sure how to determine how much
memory is being used by this object. I've read that Marshal.SizeOf()
can determine the size of the object, but I get an exception:

portion of WAV file
Hi,
I'm trying to read (to end up plotting it and playing it) only a
_portion_ of a wav file. Looks like the System.Media.SoundPlayer class
is conceived to load and play entire wav files. Is there a way, maybe
using SoundPlayer in conjunction with streams, to do what I want?
Are there other better classes?
Thank you,

I can't seem to get them to work. I want to account for 1 or 2 digits in

After not getting the correct result I put it down to the simplest pattern

Regex question
This is really a regex question.
I am wonding if anyone knows a good Regex expression that would pull a valid
date from a string.
I have used:
strValue = Regex.Replace(valueIn, @"[^\d/]", "");
which works most of the time.
But I have some cases where I have strings like:
05/07/08(-4%)
09/19/08 DOM 55
09/19/2008 DOM 53
FOR 09/15/08 -23
