To link two pices of codes with condition

Question

Hi,

 

I have four textboxs (txtResultA, txtResultB, txt_SoldForResultA, txt_SoldForResultB).

 

The two txtBoxes: txtResultA, txtResultB doing one operation. But when one of these txtBoxes have a number superior to another one. The result should be displayed on txt_SoldForResultA or txt_SoldForResultB.

 

For example, txtBoxA.Text (100) – txtBoxB.Text (70) = 30 (should appear on txt_SoldForResultA).

 

Another example is, txtBoxA.Text (70) – txtBoxB.Text (100) = 30. For this result should be appear on txt_SoldForResultB.

double d1, d2, total0;

double.TryParse(txtBoxA.Text, out d1);

double.TryParse(txtBoxB.Text, out d2);

total0 = d1 - d2;

txtBox_SoldForA.Text = total0.ToString("N2");

/////// Need to link these two pieces of code to do what I explained

double d3, d4, total1;

double.TryParse(txtBoxA.Text, out d3);

double.TryParse(txtBoxB.Text, out d4);

total1 = d3 - d4;

txtBox_SoldForB.Text = total1.ToString("N2");
