I am trying to convert a string into a uniqueidentifier by using the following code
string contrID = Request.Params["oId"
SqlGuid sqlID = SqlGuid.Parse(contrID
I am then putting sqlID into my SQL WHERE clause so it only pulls that record. I've double checked that the record I'm trying to pull is in the database. I am getting the error below. I don't understand what is causing it, Any Help is appreciated!!!!!!

I'm trying to get the Name of the USB device pluged in from the
RegisterDeviceNotification that I've used P/Invoke to marshal. I have
seen a similar posting on the VisualBasic newgroups but I do not know
how to translate the ReDim that occurs there into C#. Or wither this
will actually give me what I'm looking for.

set the length of the name correctly in the...

Hi,
I have being trying to get a grip of HTML data manipulation and am using the mshtml class and System.Net to retriver HTML pages.
Now as far as I can see, one can read HTML in different ways.
1. Using the WebBrowser and loading the HTML into the mshtml.HTMLDocument class and then step through the various tags (input, a), tables etc.
2. Use System.Net.WebRequest/Response to load the data into a HTML string using a Stream Reader.
Now...

HiddenField into a TemplateField. The porpose of this HiddenField is to hold
the ID of the row. Each row in the GridView shows a purchase order. This ID
column shows the ID of the purchase order. So if the user wants to delete
this purchase order then the value in the HiddenField is sent into a stored
procedure and updates the database....
So that's why I...

Hi!
While implementing a property manager (that supports key / value pairs), I
was wondering how to constrain T to a struct or string type. Basically, I
guess what I'm looking for is the common denominator for structs and strings
and while looking through the SDK I only noticed the IEquatable<T>
interface.
So I implemented the class with methods such as the following, but I'm aware
that this is not the right approach.

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,...

Hello
I'm a network technician in training and I need your help.
