You'll need to create your own control, deriving from the Control class. Override the OnPaint method in this, then use the Graphics object provided in it's PaintEventArgs argument to draw whatever you want. Hint: Graphics.FillPie might come in handy.

Doesn't really matter, UserControl allows you to use the visual designer, which you probably won't be needing in this case.

Hi All,
I am drawing rectangle on the form. (VC#)
I am able to resize the rectangle when rectangle is at zero degrees.
For example, if i want to resize top right:
rect.Y = mousepoint.Y;
rect.Height += OriginalRect.Top - mousepoint.Y;
rect.Width += mousepoint.X - OriginalRect.Right;
whereas 'rect' is rectangle after resize, 'mousepoint' is mouse pointer while mouse move.
But
When i rotate rectangle at, say 30 degrees, I have the problem, the above code won't work.
I need to change x, y, width and height. How to do it? I just want a clue.
I want to make sure that i am using Visual Studio 2005. This app is NOT WPF.
Thanks in advance.

Use the Rectangle's Inflate method.

What? You are doing your final year project, as in you have been in the class all year, and now you are doing your final project? And NOW you need to learn C#? Didn't pay attention in class huh?

Unfortunately not, however, I expect a functional prototype at the end of the second quarter, 2008. They will be issued to worthy members to combat ignorance and stupidity here at CP, free of charge.

Hello,
Any help would be great! I have tryed the (datagrid.columns[1]. visable = false) the issue is that, using this method shrinks all the rows of data in the data grid view. Even if i set the row height, it seems to make no difference. I need to set which columns are shown in code, and I change the data source for the data grid view as needed. I have also tryed (datagrid.columns[i].width = 0) and (col.width = 0), both produce the same result, the column width is changed to 0, but you can still see the column, only it appears as a line, and if you are hiding a few columns then it is very noticable. Also you can streach the columns with a width of 0 back out again.
any help would be great.
Thanks to thoes who replyed to my first question for this, I did try all suggestions.
thanks, J

Where have you tried this and what do you mean it shrinks the rows?

So this is a repost of the same question?

answer question 1: when using the (datagrid.columns[i].visible = false) method when the data grid load in the form, the row height is set to 0, even if i reset is before it is displayed it does not change. so there for all the rows appear shrinked. I do not know why this is happening, and no matter what I do, or set, it seems to set the row height to 0.
answer question 2: Yes I have posted this question before... the responses I had gotten, though helpfull, did not help with my problem, i am really stumped with this one.

You can repost this as many times as you like, but the answers (which you've already been given) does not change.

I don't agree with you. The other day, a person reposted a question to which he did not get an answer, in the hope that he would get one this time.
I happened to see his question that time and was able to answer it. At least, they stay polite by mentioning the repost fact.

That doesn't do much good except flood the forums with redundant posts.
The very reason Chris put View unanswered questions in the C# forum in each forum, so posts that haven't received any replies don't get lost.

Hello,
I hope somebody has a good explanation for this issue.
Okay I'm having troubles with the httpWebRequest method. I need to download reports from a specified server (can't give these details). Now I don't have trouble with an "HTTPS" url but I with an "HTTP" url I get the error :
error: The server committed a protocol violation. Section=ResponseHeader Detail=Header name is invalid
This the first time I got this error in c#.net. I tried this in Java and there I didn't had any problems. So I'm kind of lost.
I search the internet to see what the "ProtocolViolationException" throws. I found this on the msdn site:
ProtocolViolationException :
Method is GET or HEAD, and either ContentLength is greater or equal to zero or SendChunked is true.
-or-
KeepAlive is true, AllowWriteStreamBuffering is false, ContentLength is -1, SendChunked is false, and Method is POST or PUT.
I did an output of these properties and some how these don't have the values mention to trigger the ProtocolViolationException.
So my question is, How is this possible?
this is my testClass:
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Net;
namespace adlogix_views
{
static class httpTestClass
{
///
/// The main entry point for the application.
///
[STAThread]
static void Main()
{
string page = "";
try
{
// write a line of text to the file
HttpWebRequest wr = (HttpWebRequest)WebRequest.Create("http://www.mywebsite.com");
string userPass = "myUsername:myPassword";
string encoding = Convert.ToBase64String(Encoding.ASCII.GetBytes(userPass));
wr.Headers.Add("Authorization", "Basic " + encoding);
wr.PreAuthenticate = true;
Console.WriteLine("Method = " + wr.Method);
Console.WriteLine("ContentLength = " + wr.ContentLength);
Console.WriteLine("SendChunked = " + wr.SendChunked);
Console.WriteLine("KeepAlive = " + wr.KeepAlive);
Console.WriteLine("AllowWriteStreamBuffering = " + wr.AllowWriteStreamBuffering);
HttpWebResponse ws = (HttpWebResponse)wr.GetResponse();
Stream str = ws.GetResponseStream();
StreamReader sr = new StreamReader(str);
while ((page = sr.ReadLine()) != null)
{
Console.WriteLine(page);
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}
}
this is the output of the properties
output: Method = GET
ContentLength = -1
SendChunked = False
KeepAlive = True
AllowWriteStreamBuffering = True
I hope somebody can help me with this.
