I come again to you for help. this in my view is from the hard level. I have two forms the first has five textboxes the second is a numpad with the buttons from zero to nine, the comma, the enter and a textbox that serves as a display where I can see the values while typing. if in the first form I click on the textbox1 it will activate the numpad form. where I'll enter the value. when entering or closing the numpad I need the value to be inserted in textbox1. if in the first form I click on the textbox2 it will activate the numpad form. where I'll enter the value. when entering or closing the numpad I need the value to be inserted in textbox2. summarizing I need to find a way of form 2 know which textbox I clicked to enter the value there. Every help is welcome... thanks
