How to Get AutoGenerate Code with Strings and Numbers in C#

I agree.

You can see the method parameters though, which basically are locals; they probably included those for supporting interface documentation.

How about...

string GetRandomString(int length)//length of random string
{
   System.Text.StringBuilder sb = new System.Text.StringBuilder(length);
   Random rnd = new Random();
   for(int i = 0; i < length; i++)
   {
      sb.Append((char)rnd.Next(33, 127));
   }
   return sb.ToString();
}

Use parameters (odbcparameter). (read up on sql-injunctions)

2) use the 'code block' tags to post code

3) Your question: One way to do it would be to do a select from the user + date first. If the select returns 0 rows --> insert else --> don't insert

Nah. I only do that when a very basic question is getting asked; anyway, feel free to visit a decent book store, I could recommend the Stanford University Bookstore on the Palo Alto campus, it is quite impressive (I think it looks like an Amazon warehouse).

FYI: I added a book thread[^] on my personal CP blog for your convenience.

That's a bit far for me, but thanks none the less. I went to a book store the other day and could not even find a computer section! I'll try a different one next time...

Some good advise in your thread Smile | :)

Hi All,

I have to develop an application using C#. Application requirements is given below:

1.Automatically send job alerts to all the registered job seekers based on some criteria like
work experience,Skills etc.
2.There are about 9 lac registered users and will increase in future.
3.Once the application started will send email to all the users and after completing the
email sending to all users it will stop/pause for some time say 3 hours and after that
it will automatically started . This process will keep on repeating until administrator
stop the application.
4.Application will run on the same server where database is running.

Please suggest me how to develop the application so that it consume minimum resources of the server?

Should I develop an application or a windows service? Which will be the best solution?

Please give suggestion keeping in mind that server resources should be consumed minimum?

Please Help.

Thanks & Regards,
Dev

I'll need to keep polling for checking when to start the next batch as he wants to do this every 3 hrs.
