[C# .Net] Changing timer interval at runtime?

[Guest Dan C]

Okay,

I have one text box and one timer. I want to be able to change the interval of the timer at runtime, by entering the number into the text box and clicking OK.

In VB6, it was like timer1.interval = textbox1.text

How can it be done?

Thanks.

it's the same as in VB: just call the "Interval" property of the timer and assign to it the text from the textbox, just like in your example. But remember C# is case-sensitive:

timer1.Interval = textbox1.Text

Good luck!

You have to convert the text in the textbox to an integer. Like this:

timer1.Interval = int.Parse(textBox1.Text);

And wrap a try..catch block around it, unless you want it drop exceptions on unparseable stuff.

Okay, that worked :D Thanks for the help guys (Y)

Edit. Good tip aswell Tom ;)

Well to make life easier, I decided to use NumericUpDown control.

I tried this code, but I just get a error :/

Maybie it just a silly mistake, I have no idea.

timer1.Interval = int.Parse(numericUpDown1.Value) * 60000;

Sorry about these rather silly questions tho :unsure:

Ummmmm... you're parsing a value? Parsing can be done on Strings only i think.

Ah allright then. Well, I think'll just use textbox instead then.

Sorry and Thanks :)

Try this:

timer1.Interval = int.Parse(numericUpDown1.Value.ToString()) * 60000;

But what i don't get is, why do you even need to parse it, when the numericupdown control provides a value back, and all u need is basically (numericUpDown1.Value * 6000)

Because the data-type of the Value property of the numberic up/down control is of type Decimal, which contains extra functionality, so it must therefore be converted to an int value.

The example I gave above actually isn't very good, a better way to perform the convertion would be:

timer1.Interval = Decimal.ToInt32( numericUpDown1.Value );

Oh i always thought the value method, returned integer type.

just cast it as an int.

(int)numericUpDown1.Value

It couldn't be easier. :rolleyes:
