Hi,
the MappingName of the table style has to be set to the class name of the list class assigned to the data source. I dont know if IList is sufficient. If not take myList.GetType().Name as the mapping name.
The column style's mapping names then have to be set to the names of the properties you wish to show.

A simple example.
Suppose you have a dataSet that contains data from a couple of tables located in a Database. The following code snippet will loop through each of the records in the FIRST table of the dataSet and will display the values of the fields username and password, for each record (row). I know it's a silly example since it doesn't make a lot of sense to do something like that, but it demonstrates the way for accessing the rows in a table:
DataTable <code>dt</code> = dataSet1.Tables[0];
for(int <code>i</code> = 0; i < dt.Rows.Count; i++)
{
this.textBox1.Text.Trim() == dt.Rows[i]["Username"].ToString().Trim();
this.textBox2.Text.Trim() == dt.Rows[i]["Password"].ToString().Trim();
}
Hope this helps
Regards,

Good day to all of you, I'm an intermediate C# programmer, and I'm trying to help my friend who has a small computer rental for the monitoring of the pc use, mostly for gaming/internet. As of now, he is confined to writing all in a record book and do all by hand, so I want every computer to have a small window that has their time remaining before the computer logs off or hibernate, the workstations are being controlled by the server in the cashier. The problem is how can I access the workstations for me to control it in the server and to place small windows in them. Somebody told me that it can be done using winsock. This is my first time to handle a network related application using C#. Thanks in advance.

You can probably do it with a quick script but...
If you want to use c# the fastest way is to create a client / server app using remoting.

Can some one help me?

hi, i have tested it and it works. here are the 2 lines of my code
this.pictureBox1.DoubleClick += new System.EventHandler(pictureBox1_DoubleClick);
this.pictureBox1.MouseDown +=new MouseEventHandler(pictureBox1_MouseDown);
Make sure u get the sender and event args and no exception is skipping ur code.
I made a pic box which changes the location on double click and changes image in mouse down , show the methods code to see whats wrong.

Many Thanks,

Hi jrahma,
Get the rquired fileds from Database into a Dataset or data table. Set the Datasource , DataMember, Value member properties of the combobox control to the right columns in your dataset or table.
Thanks and Regards

I have an MDI child for and I want it to be shown maximized with preventing the user from clicking on Max, Min or X buttons on the control box.

To show MDI child as maximized, set the "WindowState" property to the value of "Maximized".
If you do not want to show the Max button, set the "MaximizeBox" property to "False".
For not showing the Min button, set the "MinimizeBox" property to "False'.
Likewise, if you do not want to show the X button (i.e., close button) on the child form, you can set the value of "ControlBox" as "False".

Hi Ashok,
I've tested your suggestion. But it still allows me to minimize the child form. Guess we need to do something more to prevent that.
Thanks and Regards

There's the SizeChanged event that will tell you when the window size has changed (minimized or maximized.) There's not a SizeChanging event to cancel the resizing that I could find, but you could immediately re-maximize your window (I don't know about flicker.)

Use the following code (i.e., in the Load event of the Child form). It should solve your problem, as I could test in my sample program. This code will give you a child window with no Max, Mix, Close (i.e., X) buttons and with fully maximized child window, as desired by you. You can still access other child windows from the Window menu of the MDI Parent window which displays links to different child windows.
private void ChildWindow_Load(object sender, System.EventArgs e)
{
this.Dock = DockStyle.Fill;
this.FormBorderStyle = FormBorderStyle.None;
this.MaximizeBox = false;
this.MinimizeBox = false;
this.ControlBox = false;
}

Ok , this time I think it is a logic error r smth... her eis the full code:
private void Tamam_Click(object sender, System.EventArgs e)
{
SqlCommand myCommand = null;
myCommand = new SqlCommand("INSERT INTO CES VALUES(@i_cesit,@i_uzunluk,@i_capı,@i_uzunlugu,@i_kavisi,@arayuz,@kod,@stok,@g_fiyat,@s_fiyat)",Form1.myConnection);
try
{
myCommand.Parameters.Add("@i_cesit",SqlDbType.VarChar);
myCommand.Parameters["@i_cesit"].Value = ıplık_cesıtı.Text;
myCommand.Parameters.Add("@i_uzunluk",SqlDbType.Int);
myCommand.Parameters["@i_uzunluk"].Value = ıplık_capı.Text;
myCommand.Parameters.Add("@i_capı",SqlDbType.VarChar);
myCommand.Parameters["@i_capı"].Value = ıplık_capı.Text;
myCommand.Parameters.Add("@i_uzunlugu",SqlDbType.Int);
myCommand.Parameters["@i_uzunlugu"].Value = (ıgne_uzunlugu.Text);
myCommand.Parameters.Add("@i_kavisi",SqlDbType.VarChar);
myCommand.Parameters["@i_kavisi"].Value = ıgne_kavısı.Text;
myCommand.Parameters.Add("@arayuz",SqlDbType.VarChar);
myCommand.Parameters["@arayuz"].Value = ara_yuzu.Text;
myCommand.Parameters.Add("@kod",SqlDbType.VarChar);
myCommand.Parameters["@kod"].Value = urun_kodu.Text;
myCommand.Parameters.Add("@stok",SqlDbType.Int);
myCommand.Parameters["@stok"].Value = (stok_mıktarı.Text).ToString();
myCommand.Parameters.Add("@g_fiyat",SqlDbType.Float);
myCommand.Parameters["@g_fiyat"].Value = (bırım_fıyatı.Text);
myCommand.Parameters.Add("@s_fiyat",SqlDbType.Float);
myCommand.Parameters["@s_fiyat"].Value =(bırım_fıyatı.Text); myCommand.ExecuteNonQuery();
}
catch (Exception a)
{
MessageBox.Show(a.ToString());
}
}
It keeps giving an error like :
"System.FormatException: Input string was not in a correct format.
at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream)
at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()
at CES.urun.Tamam_Click(Object sender, EventArgs e) in c:\documents and settings\şirin baba.aikanaro.002\desktop\ces\urun.cs:line 587"
o.k , what can be the problem , according to the articles found in net , there is nor mistake.. Has any one any idea?
Thanks a lot..

Someone please send me a code to read a binary file. The code should then change the first 2 bytes to hexadecimal codes..... the next 4 bytes to decimal.... the rest of the file can be in any format...... It should take the name of the file as a command line parameter...

Sorry, you have to write it yourself. If you have a specific problem, then you can come here and ask about it. We won't write the code for you.

Hi Prakash,
Create a binary reader by passing any stream that is created on the file. (Which you recieved through command line parameter). Use the binary readers read method to read the content into a byte array. You can use the Byte array's ToString method to convert the content to the necessary format.
fs = File.OpenRead(@"your file name");
BinaryReader br = new BinaryReader(fs);
byte[] buffer = new byte[32768];
int read= br.Read(buffer,0,buffer.Length);
mybytearry[0].ToString("X")---hexa decimal
Guess this will help you.
Thanks and Regards
