I need to convert a the string of a Text box to a Value

[Tony Hill]

I checked that twice and still missed that (Doh)

Hmmm, I'm reading back a sensor, it's giving values all over the show!

private void button1_Click(object sender, EventArgs e)
{
//int value = 0;

// MessageBox.Show(textBox1.Text);

if (int.TryParse(textBox1.Text, out int value))
{
   
    if (value > 1000)
    {
        MessageBox.Show("Here!");
    }
    MessageBox.Show(value.ToString());
}

MessageBox.Show(value.ToString());

}

value is taken as 0, despite textBox1.Text having 1234.56...

But 1234.56 is a Float/Double not an Int; the two are quite different.

Maybe try decimal.TryParse()? as the input is not an int.

You are right, but even if make 1234 it still returns a 0...

Come on Glen, you need to show us the exact code, and the exact text that you are using.

Thanks, that appears to work! :-D

Did the TryParse call succeed, return true?

Hi, This is the code I have been trying to get all afternoon!

private void button1_Click(object sender, EventArgs e)
{
float ForceVal = 0;
//MessageBox.Show(weightTxt.Text);
//ForceVal = Convert.ToDecimal(weightTxt.Text);

	//int.TryParse(weightTxt.Text, out int value);
	decimal.TryParse(weightTxt.Text, out decimal value);
   //  MessageBox.Show(value.ToString());
     if (value > 1000)
     {
         MessageBox.Show("Here!");
     }
     MessageBox.Show(value.ToString());
 
	          
}

I think that should do it. I'm hacking together a test program that interfaces to a Phidget load cell in trying to measure a value that needs to converted to Newtons from Grams (I think!). I hate the fact I wasted so much time trying to get the value to be used out of a darned label. I haven't really done much Windows code (I'm an embedded guy really) since VS2008 was the new kid on the block and times like these it shows! :sigh:

[glennPattonWork3]

Sort of I had to:

decimal.TryParse(weightTxt.Text, out decimal value);

as I was messing with a floating point number, haven't coded in Windows for a while, man it shows!

:thumbsup: Good news!
