Multiplication 1 data in textbox into another textbox and showing the result in another textbox

i know about the read only command for textboxes . I am making an app with two screens and how do I get my data from screen 2 to screen 1. Basically i multiply a number into another number in another text box and how do I put the answer into screen 1 into the read only textbox?

You can use something like these :

Screen1 (Click Me)


Screen2 (Click me)


You could consider using virtual screens, then not have to worry about transferring data between screens

Use different screens wisely

If you decided to use different screens, then you should switch them correctly, else you will run out of memory after a while...
