hello programmers, first of all i would like thank you all for your big help. Sirs ive got another problem here as you see ive created 5 textboxes where the first four would actually multiply to each other and the solution goes to the fifth textbox. My problem is when it is a whole number (1,2,3,4,etc) the formula is solving it the right way, but if it is a decimal number the the answer is wrong. Please help dont know the syntax.
Here is my code:

VB

If IsNumeric(TextBox1.Text) And IsNumeric(TextBox2.Text) And IsNumeric(TextBox3.Text) AndAlso IsNumeric(TextBox4.Text) Then
          TextBox5.Text = CInt(TextBox1.Text) * CInt(TextBox2.Text) * CInt(TextBox3.Text) * CInt(TextBox4.Text)
      End If

Solution 1

Hi. I've never coded in VB, but I think that maybe you should use CSng instead of CInt.

thanks sir

sir is there any way that in can only show two decimal places?

saxenaabhi6 17-May-11 22:22pm

you can format the string like


TextBox5.Text = Format(TextBox5.Text, "####.##")

that is four place to the right of decimal and 2 to the left

if you want to do the rounding read more about how to round the numbers

sir found the solution ^_^ thanks
TextBox5.Text = Round(CDbl(TextBox1.Text) * CDbl(TextBox2.Text) * CDbl(TextBox3.Text) * CDbl(TextBox4.Text),2)
