Asking for source code is considered rude in CP. Read the guidelines first before posting questions.

What have you tried so far? Try something on your own first.

How about you quit your pathetic attempt at being a student and do something you actually have a chance at!

I assume you are following this career choice because you think its easy money? Well, 1 - it's not easy, and 2 - because of mass amounts of idiots, it's becoming harder for the deserved people to find a job, and even then, one that will pay well!

Now, go quit your course!

Although I agree with your sentiment, please read

No insults welcome

Kind of takes the fun out of some answers tho.

Maybe we should have a standard 'students please do your own homework' page we can all link to whenever a post like this comes up.

I think that points 2 and 11 of the How to get an answer to your question[^] post at the top of this forum pretty much cover it.

Yeah, I have read that.

There is also How to get an answer to your question[^], if the OP disregards that then I reserve the right to do the same for the answer one.

I think that is fair, is it not?

Sure I won't complain Poke tongue | ;-P

But look at it this way, the 'how to answer a question' thingy might restrict you somewhat but doesn't stop you from being creative in your answers Poke tongue | ;-P

Alas, the 'how to answer' item was added because some people[1] were getting more and more agressive in the answers to retards, nitwits and the ESN[2]. As a reault Dad said we have to play nice or we won't be allowed to come over any more.

[1] I reserve the right to pretend it was not me never.
[2] Not 'Educational Special Needs' but the older meaning. The new one is just a backronym.

The easiest way is to use String.Split() method to split the string by '\n', but that would waste lot of CPU time and memory if you are going to use only one of those items in the array, try String.IndexOf() instead.

Combo box events

Hi i have come across a problem using combo box events

private void comboBox1_KeyPress(object sender, KeyPressEventArgs e)
{
   if (Control.ModifierKeys == Keys.Delete)
   {
      imageViewer1.DeleteSelectedShape();
   }
}

private void comboBox1_MouseDoubleClick(object sender, MouseEventArgs e)
{
   comboBox1.Text = "hello";
}

For some reason the above code is not fired, it is probably a simple constraint i do not know about but can anyone see why this is would not fire.

Thanx in advance

I suggest you read the documentation on Control.ModifierKeys, your code is not OK.

Ah thanx that was a silly mistake.

Modifier keys (SHIFT, CTRL, and ALT) not Del

The problem is that when run it doesn't make it that far as the events are never fired

Just found a solution so thought i would post it :

Most controls don,t fire delete on key press so override command key pressed and check value in keypress

// Override cmd key press
     protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
     {

        if (keyData == Keys.Delete)

           OnKeyPress(new KeyPressEventArgs((Char)Keys.Delete));



        return base.ProcessCmdKey(ref msg, keyData);

     }

     private void Form1_KeyPress(object sender, KeyPressEventArgs e)
     {
        if (e.KeyChar == (Char)Keys.Delete)
        {
           imageViewer1.DeleteSelectedShape();
        }
     }

Thanx for the help
George

sounds fair. Some keys are used to support editing, unless you tell the control otherwise.

User Input parameter question

Hi,

I have a FOR loop in my code which is used to scan through a excel sheet. something like this

for(int i = 250 ; i< count -1 ; i++)

Basically I want to create some kind of a provision(like a text box and a save button) on the windows forms to allow the user to the set the value of "i" dynamically using the GUI and save this value, so that the excel sheet is read from that index. How do I set such a user parameter?

Kindly let me know how to go about achieving this task,,,, or if you have better ideas.

Thanks ,

This is covered in nearly all introductory tutorials and books on C# I have ever seen.
Add a text box and a button to your form.
Add code in your button_click event to get the text value, convert it to an int and store it in some useful location for your loop to use.

But I want to save the input value so that the sheet is read from that index unless updated later by the user.

OK, save it somewhere else. How difficult can this be?

OK sir, I have managed to solve it. I save the content into a text file user streamwriter and on form load used the stream reader.
