Outputs

Hi,
What specifically do you mean by outputs and inputs?
As far as I understand your question, you could do this.
(Assuming that your using VB6, bcoz of the msgbox statement)
Dim in_put As Double
Dim out_put As Double

'get input
in_put = CDBL(textBox1.Text)
'do some calculation
out_put = A - ((B + C) + (D + F) + (G + H))
'display both input and output
textBox1.Text = cstr(in_put) & out_put

Note:
Next time, please don't cross-post on other forum groups...

I tried it didn't work. It said input_var and result_value undefined.

Hi,
Finally, I quite understand on what you mean. As i understand, your trying to create a calculator (windows style calc) application... So here's a sample routine that I think would get you started...
Dim x as double
dim y as double
'Place this code in your + button
if x = 0 then
x = CDBL(txtInput.Text)
txtInput.Text = "0"
else
y = CDBL(txtInput.Text)
txtInput.Text = x + y
x = y
end if
'Place this code in = button
txtinput.text = x + y
x = 0
well, as you see this code is just good if your doing a + and = operation. If you plan on doing all of the mathematical funcs. THen you should do some major overhauling on the code above. I suggest looking up on MSDN Docs for some help...
