I agree, newest and shiny is always best  You'd need linq to entity for this solution though and I'm not sure how performant that is at the moment.

Linq for Entities provide uptimized queries when used with the Entity Framework, but it's not needed to query a collection.
From MSDN[^]:
.NET Language-Integrated Query defines a set of general purpose standard query operators that allow traversal, filter, and projection operations to be expressed in a direct yet declarative way in any .NET-based programming language. The standard query operators allow queries to be applied to any IEnumerable<t>-based information source.
With regards to performance I am quite sure it will be fast enough to handle the size of most collections encountered by someone who are at the level where they have to ask for help getting the item sorted in the first place.

After you set doublebuffer = true how do you swap buffers? Thanks in advance.
The most knowledge doesn't mean the most wise...

Hi,
GUI parts implement double buffering by:
- allocating a memory buffer
- drawing (both background and foreground) into that buffer
- then blitting everything to the screen
The painting code remains exactly the same, the Graphics class and the underlying stuff
takes care of it all.
As a result the paint operation seems much faster, in particular there is no
time gap between a paint background then paint foreground any more.
The programmer is not involved in this, he does not manipulate the buffer.
(it is not a ping-pong buffering system, where one buffer is painted in while the
other would be shown, and both would get swapped at the programmer's discretion).

It's cunning the way they named it DoubleBuffered and made it a boolean. Damn them for the way that they hide these things.

Check on your markup view of new page on top the line where is defined class inherited, language... Sample:
...
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="SamplePage.aspx.vb" Inherits="SampleProject.SamplePage"%>

How can you put an image in an imagelist from a file in your solution?
Dany

Add the images you want to add to the imagelist, to your project resources.
Then to add an image, you would do this:
ImageList1.Images.Add(Properties.Resources.Image1);
That should work.

Hello there!
You need to create a setup project to install your application and its dependencies and to run your sql scripts to setup your database.

Hi all,

Thank you

If you are using the Office Interop, then no it will not work. This is why I never use the office Interop. If you use the ole db provider for the db then it will work.

I am using the Oledb provider, do you have another idea or advise.

Hi,
I have been looking to find a way to draw lines onto a richtextbox control but have not been able to find anything on the web (or here). To clarify, the specific application I am working on has a requirement that the GUI looks like a piece of lined paper (i.e. I do not just want to put a bitmap into my control) which the user can type onto.
Solutions I have looked at so far include (but are not limited to):
1) Subclass richtextbox and override OnPaint to draw lines after calling base.OnPaint -> This does not work which seems to be because of the way MS implemented the base method, but I don't want to have to rewrite the entire drawing of the control if I can help it
2) Put a 50% transparent form over the top of the rtb and draw lines onto it -> I found this idea somewhere but it seems very messy, and makes it trickier to type into the rtb at the same time
3) Copy a row of - or _ characters to the clipboard and paste into the rtb -> User typing then messes up the look
4) Insert bitmap images into the rtb -> doesn't work for same reasons as 3
5) Place an rtb onto a user control or form and draw lines on the form in correct positions -> Lines get drawn underneath the control
6) Use BitBlt directly to draw on top of the control -> I haven't tried this one yet, but I would rather avoid using Interop if I can
Given that these solutions do not work (at least as far as I can tell), can anybody suggest any other approach or any references I might look at?
Thanks in advance,
Chris

I don't know how to do this with the WinForms RichTextBox, but have you looked at using the WPF RichTextBox? It's so much more powerful and flexible than that WinForms one, I suspect it would be relatively easy to do there.

I hadn't heard of WPF until I just read your post so I have just looked it up - am I correct in thinking this is a .Net 3 feature? I haven't upgraded from 2 yet...perhaps it's time to get around to it! Anyway I will look into this a bit. Thanks for the reply
Does anybody have any other suggestions (.Net 2 or 3)?
Thanks,
Chris

Hi,
I haven't done this, but maybe you can:
1. use a Panel, and draw lines on it with Graphics.DrawLine
2. put a RichTextBox on top of it, and set its BackColor to transparant.
