Yes, I've written a series of articles on image processing in C#, the first one has a greyscale function.

Well, I finally got the C# books that were recommended by CP users (or maybe I should say book). I bought "Inside C#" by Tom Archer, and "C# and the .NET Platform, by Andrew Troelsen. The second book was supposed to Charles Petzold's latest. Could anyone give me a comparison on what they thought between Charles Petzold and Andrew Troelson? I'm not sure if it's worth returning the book and getting the one that I was supposed to.
TIA

They are totally different - C# and the .NET platform is a whirlwind tour of C# and .NET, and the Petzold book covers in depth GDI+ and all the aspects of writing client apps in C#. I'd return it, you're going to have heaps of double up with Tom's book.

I was afraid of that  Hopefully returning it won't be too painful. Thanks for the help Christian.

By the way, in conjunction with what Christian said, since both Charles and I write for MS Press, our books are intentionally designed to complement one another. This is why he only has a few pages on C# syntax (while that is almost my entire book) and I don't cover GDI+ at all (where that's the focus of his book). That way, there is little to no overlap. In addition, to mine and Charles' books, you will definitely want to get Jeffrey Richter's book as it goes into a lot of detail with regards to the .NET runtime.

By the way, Tom, Amazon stitched me up with your book, in that they shipped me the Richter book, but have yet to ship Inside C# 2nd ed ( which frankly was the main one I wanted ). So I don't think they have it to ship yet, I dunno about anyone else though.
I'm sure I'll get it eventually, but I was a bit miffed because I asked them to ship them all at once.

I hate that when you pay someone to screw up  Oh well, you should have it shortly as I just got mine in the post.

Well, I think I'll be thanking *you* for the support shortly. I'm still a little lost C# wise, at least compared to C++.

When I last checked Amazon.co.uk (Tuesday) was still listing the first edition and not the second. I can't wait to get my hands on the second edition too.

Absolutely agree, Jeffrey Richter's book is awesome! Really teaches you an awful lot, I'm quite looking forward to getting my hands of Jeff Prosise's .NET book when its eventually in the shops -- the MFC book had to be the best one I've read particularly when I was first starting with VC++.
Anyone got any kind of insider knowledge about how good it is?

Can anyone help with this question - i'm trying to trap the MouseWheel event of a scrollbar control placed on a form, and although this doesn't appear as an event at design-time i can create an event at run-time to handle it, ie:
vScrollBar1.MouseWheel += new System.Windows.Forms.MouseEventHandle(WheelEventHandler);
Problem is that this doesn't trap the wheel scroll event at all even although i'm convinced this is how to do it.
I know it ain't a visible event at design time and similarly it's a MouseEventHandler instead of just an EventHandler (used for MouseDown/Hover/Leave etc) and bearing this in mind how do i trap it?
Cheers

Have you tried to override the event?
<code>
protected override void OnMouseWheel(System.Windows.Forms.MouseEventArgs e)
{
MessageBox.Show("I moved the mousewheel");
}
</code>

Yeah i've tried overriding it but nothing. I've also tried creating a UserControl (Windows Control Library) and inheriting my class from "System.Windows.Forms.VScrollBar" but this doesn't do anything for the MouseWheel event, although it does seem to work for SystemEventHandlers as i suggested earlier.
Another point to note is that this is only a problem on our Win2000 boxes - we've got an XP box and the original "vScrollBar1.MouseWheel += New etc etc..." works fine on that, even although MSDN suggests Win2000 should be OK as well - a bug....?

OK now for the most bizarre solution of the day....if ur Wheel Settings on Control Panel / Mouse Properties has 'Enable Enhanced Scrolling' checkbox then Uncheck it and hey presto - it works again.
Seems that even although you have to check this to modify the no. of 'scroll by' lines, it has to be Unchecked to allow the scrolling wheel facility in the first place!
Not only does this seem a bit back-to-front but not all mouse devices have them so watch out - also it's not something that can be found by interrogating the SystemInformation options in the code either...

I have a program which calculate the time i spent on the phone and I want to create a report to print. I got it by drawing each control on my form and the text, the image also, but i want to know if is there a solution I can use for all my futur report project. I tried Crystal Report but It's too hard for me, i don't understand how it's work and I don't want to spend my time on learning CR.
Anyone have an answer please ??
Thanks

... it will change all text when next text will be added!!!!
Like this, in my RichTextBox I handle TextChanged and do this code in it:
private void richTextBox1_TextChanged(object sender, System.EventArgs e)
{
// 'str' is the palayer name
String str = "Rickard Andersson:";
int howMany = str.Length;
int startAt;
// loop through the RichTextBox whole text to find 'str'
// with no Bold style... if we find 'str' with no Bold syle
// then we make it Bold
do
{
startAt = this.richTextBox1.Find(str);
if(startAt != -1)
{
this.richTextBox1.Select(startAt,howMany);
Font oldFont;
Font newFont;
// Get the font of 'str'
oldFont = this.richTextBox1.SelectionFont;
// If we found a 'str' with no Bold style, make 'str' Bold
if (!oldFont.Bold)
{
newFont = new Font(oldFont, FontStyle.Bold);
// Give the non-Bold 'str' bold style now
this.richTextBox1.SelectionFont = newFont;
this.button1.Focus();
break;
}
}
}
while(startAt == -1);
}
I have test this code with two buttons on my form, those add text like: "Rickard Andersson: Hell oman" and "Mike: Hello you too!"
And if "Rickard Andersson: Hell oman" will be added the "Rickard Andersson:" will be bold. But when I press the other button which add "Mike: hello to you too" ALL text will be bold instead of no change at all... what's wrong, dude!?
