Hi,
I want to sublty allert my user to missing data with a visual prompt slighlty more stark than the basic "(null)" given by a data grid. Ive changed the message with a custom colomn style BUT i want to make that message bold and a different colour.
Is there an easy way to achive this using settings?
Thanks.

For a DataGridTextBoxColumn you can access the embedded TextBox using the DataGridTextBoxColumn.TextBox property. If you want more control - such as encapsulating the data logic for displaying text differently based on the current value - implement your own DataGridColumnStyle and draw the text and background as you want in your DataGridColumnStyle.Paint override.
There is at least one example of this here on CodeProject. Please search the articles using "DataGridColumnStyle" and you should find it.

hi,
I have a question. How can I insert/paste text from a clipboard into the current cursor position of a rich text box.

Quit simply you can call RichTextBox.Paste. You can either do this using the first available and acceptable format by calling the method with no parameters, or pass the data format you want. See the documentation[^] for the Paste method for more information.

I have an asynchronis socket class written by my manager that uses Socket.BeginSend(...) to send messages over the socket. He uses this overload of the function:
public IAsyncResult BeginSend(
byte[] buffer,
int offset,
int size,
SocketFlags socketFlags,
AsyncCallback callback,
object state
);
where the delegate callBack should call another function in the code, HandleSend, which does some important things after a packet is sent. The program goes all the way through the BeginSend function, but randomly, the callBack delegate seems to stop calling HandleSend. I am not sure if this is the problem, but it really looks that way. I don't think I understand how the function BeginSend works in conjunction with the AsyncCallBack delegate. Could there be a thread safe problem with this logic?
Please help!
Thanks,
Lilli

Here is my problem. I'm trying to draw a vector on a graph on a WinForm.
I want an arrow (triangle) on the end of the line. I have two files.
My pens are "cycled" on each paint event (0, 1, 2.. repeat). Everything works ok. I just can't seem to figure out how to draw an arrow....
Complex.cs
///////////////////////////////////////
private double x
private double y
//Constructor
public Complex()
{
x = 0;
y = 0;
}
public Complex( double _x, _y)
{
x - _x;
y = _y;
}
/////////////////////////////////////////////////////////////////////////////////////////////////////Form1.cs
public Pen[] activePen = new Pen[] { new Pen( Color.Blue, 2 ), new Pen( Color.Green, 2 ), new Pen(Color.Red, 2) };
private int _penIndex = -1;
/////////////////////////////////////////////////////////////////////////////////////////////////////////
private Pen GetNextPen()
{
_penIndex = (_penIndex + 1) % 3;
return activePen[_penIndex];
}
//////////////////////////////////////////////////////////////////////////////////////////////////////
g.DrawLine(GetNextPen(), 250, 250, x, y );
/////////////////////////////////////////////////////////////////////////////////////////////

Look at the Pen.EndCap property. There is an enumeration that will allow you to put arrows on your line.

Andy . Thanks. My problem is I can't figure out HOW to put the code in.
Where would it go?
|
|
|
|
|
Pen p = new Pen( Color.Blue );<br />
<br />
p.EndCap = System.Drawing.Drawing2D.LineCap.Triangle<br />
You need to do this for the pens that you want to have a cap.

Have you read what I wrote you?
I gave you the code and I said you could place it in the constructor... 
|
|
|
|
|
Sorry - I'm new to this. WHICH Constructor? The Form or the Complex class?
Thanks.
|

In the constructor of the class where the Pen array field is defined and being used.

I'm starting up on big project that will take much of my time in next year or two. Until now I was mostly self-employed on small projects so I didn't spent so much time modeling system before implementation. Sure, I wrote use cases now and then, draw UML in Visio but it wasn't matter of life and death.
But because of scope in next project I'm kinda frighten that sooner or latter I along my team will get lost in poorly documentet envoirement where no one will know what is truly purpose of system's part that they are working on or how to connect it to another.
So, since lot of envisioning and planning are up ahead I was thinking about sharing tought or two regarding UML modeling, drawing use case diagrams and similar subject. What programs for creating solution architecture you people recommend? I'm in need of something that can truly succesfuly reverse-engeenier and forward-engeneer (UML <-> C#.NET solution). What are your views on 2005 generation of tools (VS.NET 2005 with Visio 2005) that are comming next month? Anyone played long enough with Beta?
Tnx!

How can I rotate a picturebox? Not just the image inside, but the box as well. I want to rotate the WHOLE control. Any help would be great. Thanks.

I need to alter a C# Windows application to be a C# Web application.
From the documentation I have read that IIS needs to be installed on the development machine to effect this. Is this true ?
I don't have IIS installed as I use Apache. Can this be made to work ?

Alf Stockton
