That error usually occurs when there is no data in the data readers, ie, dataReader.Read() did not return true. It is probably a small error in your code.

why would this make your kid happy?

A piece of paper with the tables on would be much better for them, that way they can take into school and use them to cheat

plus you should prob have an option to set what multiple they want to generate upto

DLL and C# classes

ScotDolan10-Feb-09 4:36

10-Feb-09 4:36

I have developed a C# class library that is used to control network communication of two application. The class provides all the functions/methods necessary to initialize, control, implement communications. I would now like to make this class into a DLL or someother object so that communication code is compiled and maintained sperate of the two application.

Question? Is Putting the C# communication code into the DLL the right solution for the problem? If not what is the right solution.

We don't have your problem definition so we can't know that. However there is nothing inherently wrong with it. Designing libraries can introduce different problems like configuration or security.

10-Feb-09 4:36

hmmm... well if you need them to stay in your array then maybe you need to add a 'group id' property to your graphics object

i would suggest a groupObject that contains a collection of graphics objects;

Then you have a collection of groups rather than directly collecting graphics objects.

Just one approach to think about

Hello ,

i find this code in C#

public static Image GetImageFromBase64String(string str, bool makeTransparent) <br />
		{<br />
			return GetImageFromBytes(Convert.FromBase64String(str), makeTransparent);<br />
		}<br />
 <br />
private System.Windows.Forms.PictureBox pictImage;<br />
pictImage.Image =GetImageFromBase64String(txtinput);<br />

in asp they aren't a method Image?

public static Image GetImageFromBase64String(string str, bool makeTransparent) <br />
		{<br />
			return GetImageFromBytes(Convert.FromBase64String(str), makeTransparent);<br />
		}<br />
<br />

I think you are getting confused between PictureBox control and image itself. Picturebox is a control and you can assign any image to it in Windows forms. where as in asp.net Image is image itself. You need to specify either the url of the image or you can write the image to Response.Outputstream to display it on web page. You can't
set the Image in web application as you can set it in windows app.

In short you need to save the image to temp folder and set the ImageUrl property

OR

Write the image to Response's Outputstream as byte.

Why do i get This Error ??????

i have a server and client networked application , each time i test them , gives me an error "Unable to read data from the transport connection: The I/O operation has been aborted because of either a thread exit or an application request.
"

Here is the code for the client , knowing that the server doesn't disconnect the current client , the server still see the client as connected

the client code as follows :

<br />
<br />
<br />
<br />
<br />
<br />
void RunClient()<br />
        {<br />
            try<br />
            {<br />
                IPAddress ip = IPAddress.Parse("127.0.0.1");<br />
<br />
                int port = 5079;<br />
<br />
                IPEndPoint ipendpoint = new IPEndPoint(ip, 5079);<br />
<br />
                //create the tcp client<br />
                client = new TcpClient();<br />
<br />
                client.Connect(ipendpoint);<br />
<br />
                Console.WriteLine("The Client has been Connected Successfully");<br />
<br />
                //begin Reading <br />
                lock (client.GetStream())<br />
                {<br />
                    (client.GetStream()).BeginRead(data, 0, data.Length, new AsyncCallback(IASyncResultCallBack), client);<br />
                }<br />
                <br />
<br />
            }<br />
            catch (Exception s)<br />
            {<br />
                this.Invoke(new SetText(SetTextMethod), new object[] { s.Message });<br />
            }<br />
        }<br />
<br />
 void IASyncResultCallBack(IAsyncResult ar)<br />
        {<br />
            try<br />
            {<br />
                //get the tcp client instance<br />
                TcpClient currentclient = ar.AsyncState as TcpClient;<br />
<br />
                if (currentclient != null)<br />
                {<br />
                    if (currentclient.GetStream().CanRead)<br />
                    {<br />
                        //get the instance of the data<br />
                        int count = (currentclient.GetStream()).EndRead(ar);<br />
<br />
                        if (count <= 0)<br />
                        {<br />
                            //disconnect the current client<br />
                            currentclient.Close();<br />
                            currentclient = null;<br />
                            GC.Collect();<br />
                            return;<br />
                        }<br />
                        //build the Received Text<br />
<br />
                        ReadText(data, 0, data.Length);<br />
                    }<br />
                }<br />
<br />
                //now begin Reading again<br />
<br />
                lock (currentclient.GetStream())<br />
                {<br />
                    currentclient.GetStream().BeginRead(data, 0, data.Length, new AsyncCallback(IASyncResultCallBack), currentclient);<br />
                }<br />
            }<br />
            catch (Exception s)<br />
            {<br />
                this.Invoke(new SetText(SetTextMethod), new object[] { s.Message });<br />
            }<br />
        }<br />

The error is in the following line of code

<br />
 int count = (currentclient.GetStream()).EndRead(ar);<br />
<br />

br mode="hold" />when the compiler executes the following code it jumps to the next catch block giving the above error statement .

so what is wrong ????

Human knowledge belongs to the world.

I have used the XMLTextReader class to read the data from XML file and displayed
it in a listbox control...
XML file contains a path ...

Now i want to create a DataGrid having a column named Path, and
display the path in it...

I used the following code to create DataGrid..but it does not display
it..What changes should i make inorder to create the grid?Thanks for any help in advance.

private void SetupGrid()
       {
           DataGrid dg=new DataGrid();
           this.dg.Location = new Point(100, 200);
           dg.CaptionText = "Table";
           dg.Name = "Table";
           dg.Visible = true;
       }

Aren't you missing two statements?

dg.Columnn.Add(...)<br />
dg.Show()

And you are also not binding the datasource? If you bind it properly, you don't have to create a column.

I will assume you are using windows ... so you can usually cheat and use the file extension to determine the appropriate content-type. After that you could examine the file contents for known header information. However, the most accurate would be the Windows API: http://msdn.microsoft.com/en-us/library/ms775107(VS.85).aspx[^]
