Hi,

a chess program that plays a mediocre game and has any chance at ever beating someone is a major undertaking, my rough estimate would be some 25 thousand lines of code.

If you are rather new to programming, if you are rather new to the language you intend on using, or if your largest program sofar is smaller than some 5000 lines of code, I strongly recommend you to reconsider, and first do something less ambitious.

You might want to solve the 8-queens problem first: how to put 8 queens on a chess board in such a way they can;t capture each other. That one can easily be solved in 500 lines of code.

The next challenge should be a program that solves "mate in 2" problems; that one requires full impementation of the rules of chess, and already needs some attention to performance concerns.

When you have finished a sufficient number of such smaller tasks, you may or may not be ready to create a true chess game.

FYI: the GUI of a chess game is less than 1% of the effort; there are many available freely on the web.

Smile | :)

With the limited information you provided I would guess that the date is saved in the wrong format. Hence the database thinks the day is the month and vica versa.

SQL-server has a format that always works: yyyyMMdd. Easy to convert it to that format with date.tostring("yyyyMMdd")
Don't know if it works for oracle or not. If not I'm sure there is a similar format for oracle.

On a side note: 'need help' isn't a very good subject, it says nothing about your question.
Better would have been: 'Error saving date into oracle db.'

I'v never used oracle but I would think that as with sql you can provide parameters with your command.

Use those and they should format your date and time correctly, you also prevent sql-injections (read up on those)

How do I search for text in PDF through C#.Net.

What have you tried so far?
I found a lot of pdf components for the .net framework by searching for read pdf .net in google.
The approach to search fro the string would be to extract the text from the pdf - through whichever component - and then search the text.

1. When I make a Setup of a project today (i.e.,14 July, 2009), how to lock that setup such it should not work ofter some days(consider after 20days, i.e., 3 August, 2009).

How can make this?
2. If the setup is installed on a PC today, it also should not show its effect after 3rd August, 2009, eventhough it is not uninstaled?

How can lock the setup according to date or no.of days?

You can write the installation date in a persistent place (registry, file, database etc.) during the installation. You should be able to do this a Custom Action[^]
Every time your application starts check this date and do a validation.

Hi,

Using GDI32 dill i'm trying to build a form with curve, it works fine, as i've mentioned FormBorderStyle as NONE it is appearing entire screen and hides system task bar. How to avoid this?

<br />
<br />
Screen screen = Screen.PrimaryScreen;<br />
<br />
Region = System.Drawing.Region.FromHrgn(CreateRoundRectRgn(0, 0, screen.WorkingArea.Width - 60, screen.WorkingArea.Height - 60, 20, 20));<br />
<br />

What in particular do you want to avoid?
'appearing entire screen' or 'hides system task bar' ?

Hi,
Is this correct?
I am not sure why I get unknown username or bad password.
Note that the login and password I enter are both correct.
Is there something wrong with the way I am setting the username and password?
Thanks

private void CheckLogin()
{
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = "cscript.exe";
process.StartInfo.Arguments = strScriptPath;
process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;

process.StartInfo.UserName = "myusername";
System.Security.SecureString strPassword = ReadPassword("password");
}

public static System.Security.SecureString ReadPassword(string password)
{
System.Security.SecureString secPass = new System.Security.SecureString();
for (int i = 0; i < password.Length; i++)
secPass.AppendChar(password[i]);
return secPass;

It doesn't look like that you're setting the password on the process.StartInfo.Password property....

Is the account that you're using a domain account? If so, you might need

process.StartInfo.UserName = "domain\username";

for it to work properly.

You can quety WMI with System.Management Namespace

Here is an example. ReleaseDate property is what you are looking for

private void Form1_Load(object sender, EventArgs e)
 {
     List("Select * from Win32_BIOS");
 }

 private void List(string query)
 {
     ManagementObjectSearcher m = new ManagementObjectSearcher();
     m.Query = new ObjectQuery(query);
     foreach (ManagementObject mo in m.Get())
     {
         foreach (PropertyData pd in mo.Properties)
         {
             if (mo[pd.Name] != null)
             {
                 if (mo[pd.Name] is string[])
                 {
                     foreach (string s in (string[])mo[pd.Name])
                     {
                         MessageBox.Show(s);
                     }
                 }
                 else
                 {
                     MessageBox.Show(pd.Name + ":" + mo[pd.Name].ToString());
                 }
             }
         }
     }
