Hi ppolymorphe. "manually setting" is not the right verbiage I should have used. I would write an algorithm which would generate 64 tables, each table consisting of 8X8 squares. The queen is placed on square 1 for the first table… and so forth until the last table… she is placed on square 64.
Each table has Boolean true/false squares. All I have to do is looked at the correct table depending what square she is on and the square I am interested in would return the correct Boolean value.
Thanks for your reply.

Once all tables prepared, there is nothing faster than loading the table.

Hi ppolymorphe. I will now have to write an algorithm is generate these tables. Nothing easy but doable. 64 bytes X 64 bytes: I will stick them in memory.

Bits might be more efficient: 64 bits fits in a single machine word on most machines these days, and the conversion from coordinates to mask is trivial:

C#

long bitmask = ((long)1) << ((y << 3) + x);

Where x and y are integer coordinates.

Thanks OriginalGriff, I will try that and see how it works.

You're welcome!

It's not so bad, as suggested you can use bitboards (which will be useful when using them too, giving trivial intersection tests and so on), and because this is chess, this is all already known: chessprogramming - On an empty Board[^] gives the initialization routines for various attack masks, you can combine them here because you don't need the separate components.

Thanks Harold, I did not realize how extensive bit tables are being used.

Hi
I want to add a session in the webMethod. but it ignores it totally

C#

[WebMethod (EnableSession = true)]
        public string GetTasksCountWebMethod()
        {
            int result;
            
            if (Session["tasks"] == "" || Session["tasks"]==null)
            {
         //somecode
                Session["tasks"] = result.ToString();
                return result.ToString();
            }
            else
            {
                return Session["tasks"].ToString();
            }
           
        }

Thanks

How do you know it ignores it? I assume Session["tasks"] is null? Check Session.SessionID. Also, how are you calling the webmethod?

Hi all

I've been trying to add sql data base on my connention windows properties but

but the "select or enter database" option do not exsist.

You're going to have to describe what you're looking at, which windows and in what application. We can't see your screen or read your mind.

Hi sorry for the lake of information so i'am talking about visual studio. in my case vs2013.
And when i am trying to add sql server connection on my server explorer (right click )

The "Select or enter data base name " drop down list from Add connection windows property is missing. The only why to the add relevant connection is to modify connection and add a the intial catalog by manual. what should i do in order to avoid set the initial catalog manual on Add Connection windows

The first thing you get asked when "Adding Connection..." is to specify what kind of data source to use. You're telling the system what type of database engine you're connecting to, be Access, ODBC, SQL Server, Oracle, ... and which provider to use to get at it. Once you pick that THEN you get to pick the database server (if applicable) and database name.

Hello,

I want to add an application to windows firewall exception in Standard user without prompting for admin password.
I don't want to store my password of user who have admin privileges and later call it in standard user.

How can I achieve this ?

AFAIK, you can't.
And if you think about it, that's for good reasons.
If your app could change firewall settings without Admin privileges, then so could any other app - including a lot of nasty ones that would really like to open holes in your firewall as a side effect!

Be glad you can't - or half your system security would disappear overnight...

Yes, I got the same answer everywhere. But I got this doubt because of Tally.ERP 9.
I am using Tally.ERP 9 which is installed in Local server ( Requires admin privilege to install). When I access that application remotely in standard user the Tally.ERP 9 gets added to firewall exception in Local PC. (There is no common users in Server PC and Local PC)
How Tally.ERP 9 added without admin privileges ?

How do you do that? Web browser, local client application, RDP, ...?
Your problem in understanding the firewall settings is likely based on your problem in understanding that mode of access.

You can't. Simple as that.

I want to display the file name in the right mouse button menu, similar to the function of 7--zip

example

You'd need to write a shell-extension if you want to hook into the shells' menu. Have you considered searching the articles on this site? Smile | :)

Hi,

I have below code to send email to customers but sometimes it's failing because of slow internet and sometimes it show the please wait splash for long time.

I want to know how can I just send it in the background and keep retrying for x number of times without disturbing the users with Please wait splash or error messages?

C#

email_body = new StringBuilder();

email_body.Append("<html>");
email_body.Append("<body>");
email_body.Append("Please do not reply to this message. Replies to this message are routed to an unmonitored mailbox.");
email_body.Append("<hr>");
email_body.Append("<img src='cid:" + email_logo.ContentId + "' align=baseline border=0>");
email_body.Append("<br><br>");
email_body.Append("Dear " + customer_title + first_name + ",");
email_body.Append("<br><br>");
email_body.Append("We are glad to inform you that your order# " + order_id.ToString() + " has been delivered / picked up at " + MarkAsDeliveredForm.dateDeliveryTime.Time.ToString("HH:mm") + ".");
email_body.Append("<br><br>");
email_body.Append("We appreciate your business and encourage you to reach out to us for all your occasions.");
email_body.Append("<br><br>");
email_body.Append("<center>THANK YOU FOR CHOOSING <a href='http://www.cakeboutiquebh.com' target='_blank' style='text-decoration: none;'>CAKE BOUTIQUE</a></center>");
email_body.Append("<br><br>");
email_body.Append("<img src='cid:" + email_footer.ContentId + "' align=baseline border=0>");
email_body.Append("</body>");
email_body.Append("</html>");

mail_message.Subject = "Your Order# " + order_id.ToString() + " is Delivered";
mail_message.IsBodyHtml = true;
mail_message.Body = email_body.ToString();

smtp_client.Port = 587;
smtp_client.Credentials = new System.Net.NetworkCredential("noreply@mydomain.com", "xxxxxxxxxx");
smtp_client.EnableSsl = true;

smtp_client.Send(mail_message);
