simple simple question need FAST help!

Hi,

 

I'm in need of some QUICK help!

 

how do i write a statement so that value 1 and value 2 check value 3 to see which value (1 or 2) is numerically closer to value 3?

 

to explain this tongue-twister further...

 

private int hello = 21;

 

lblgoodMorning (has a value of 13)

lblgoodBye (has a value of 10)

 

in this case, a message box would display lblgoodMorning is closer!

 

 

Many Thanks

Just subtract and take the absolute value.

if (Math.Abs(value1 - value3) > Math.Abs(value2 - value3)) ...

Thanks for your quick reply. I entered the following...

 

 

void BtnBankStickClick(object sender, System.EventArgs e)
	{
		if (Math.Abs(lblRandom - thisScore) > Math.Abs(lblBankRandom - totalScore))
		{
	lblplayerWin.Show();
		}}

 

 

but i get the following error message...

 

 

Operator '-' cannot be applied to operands of type 'System.Windows.Forms.Label1' and 'int'

 

any ideas?

You need to access the text in the label and convert it to a number.

int.Parse(lblRandom.Text)

[snarfblam]

You can't compare a label to a number. One is a number, and the other is... well... a label. Try this:

void BtnBankStickClick(object sender, System.EventArgs e)
       {
           if (Math.Abs(Int32.Parse(lblRandom.Text) - thisScore) > Math.Abs(Int32.Parse(lblBankRandom.Text) - totalScore))
           {
       lblplayerWin.Show();
           }} 

You have to parse the text of the labels. Note that this will cause an error if either of the labels' text is not a valid number.

That worked perfectly. Thank you so much!

 

Do you know how could i go about reloading the entire form from scratch on the click of a cmd button?

[thenerd]

Like, restarting the program? or clearing the form?

 

Clearing the form is me.invalidate()

 

Restarting the program, the only way I can think of is to simply reset all the variables you used. Maybe have a sub that runs in the beginning that resets all variables, and then run that again...

Me.Invalidate will force the form to repaint itself rather than clear it or 'reset' it.
