An obvious way is to write a system where it chooses moves randomly or semi randomly ( prefer the middle, then prefer the corners, etc, or whatever you think ) and remembers which moves lead to it winning. Obviously, some basic 'finish the row if I can win this turn' code also makes sense to have.

I dont think you will need much in the line of AI. you could simply calculate all available moves and assign a weight to each move and choose the best one. You could even use some kind of probability to "see ahead" to try to guess what the opponents best moves may be given a certain move.

there're only 9! (363k) potential games. Brute force is a viable option.

Agreed! Not very elegant but certainly viable.

I got to the same point a couple of years ago.

As already stated, brute force (check every move possible) is viable in TTT as the number of moves is quite small.

You might also like to read up on AI algo's like AlphaBeta - there is LOADS of reading online about AI.

My head got a bit swallowed up by it all and thats why I never got any further with my TTT game. But I did learn a hell of alot anyway.

Will the form be maximised ? If not, the best you can do is catch the moving event and move it back.

I want to create a spooler service (windows Service) which spools the job (which has to executed in time) in message queue.
What will happen if the system crash occurs or the system is restarted.
Is it possible to recover and restart it?

you can set the start up type to automatic, you will have to program the recovery yourself because if it crashes in the middle of some work, that work will be lost.

You can use the Microsoft Message Queue (MSMQ):

This provides you with the ability to have a persistent and even distributed queue.

Heres an article on using it from c#:

navigating using arrows keys in Datagridview with combobox

I have combobox column in DataGridView.
Up and down error keys should be used to navigate previous and next row in
grid.

For this I override them in ProcessCmdKey() event.

When combobox dropdown menu is open arrow arrow keys should move to previous
and next item in
dropdown menu instead of moving betveen rows.
How to check that combobox dropdown menu is open in ProcessCmdKey() ?

DataGridView ProcessCmdKey() method:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {<br />
<br />
const int WM_SYSKEYDOWN = 0x104;<br />
<br />
if ((msg.Msg == WM_KEYDOWN) || (msg.Msg == WM_SYSKEYDOWN)) {<br />
 switch (keyData) {<br />
  case Keys.Down:<br />
   if (this.CurrentCell is DataGridViewComboBoxCell) {<br />
    CurrentCell = Rows[CurrentCell.RowIndex + <br />
1].Cells[CurrentCell.ColumnIndex];<br />
    return true;<br />
   }<br />
   break;<br />
<br />
  case Keys.Up:<br />
   if (this.CurrentCell is DataGridViewComboBoxCell) {<br />
    CurrentCell = Rows[CurrentCell.RowIndex - <br />
1].Cells[CurrentCell.ColumnIndex];<br />
    return true;<br />
    }<br />
   break;<br />
   }<br />
 return base.ProcessCmdKey(ref msg, keyData);<br />
}

So how can you conclude from what somebody posts on a forum?

That's good to know. But in an interview situation the interviewer wants to know about YOUR experience. Not the experience of skilled people that volunteer on internet forums.

Did you get asked these ? What do you think the answers are ? These are very entry level questions, I have to say.

In that case, you'll never be a programmer. Being able to do research is a vital skill
