I'm making the calculator similar to the windows one (standard)

I have problems with 2 functions one is button , (for making decimals) and function that will prevent someone to paste text into the txtbox.

Please someone help me

What exactly are your problems? Are you unclear on how to create these functions? You need to provide a little more detail.

well i have no clue about the code for , button

and i have some problems with the code for txtbox and don't know what function and syntax to use, i did make it to prevent somebody to enter text but i don't know how to make it prevent text pasting.(i need a function that looks at txtbox when somebody pastes into it, it starts and checks the entry and if non numerical string was entered it deletes txtbox)

try this.

dim a as integer
a=instr(display.text,".")

if a = 0 then
display.text = display.text + dot.text
else
display.text = display.text
end if



display.text it is textbox name
dot.text it is dot button name

cool works but there is a little problem you can make 5 commas and you get the error

solved

instead of a=instr(display.text,".") you have to write a=instr(display.text,",")

tnx a lot


anyone knows how to make someone to prevent pasting text and only allowing numbers to be pasted in txtbox

How about the IsNumeric function to make sure it is a number?
