i am writing my very first program with visual basic 2010. my question:
textbox1 + textbox2 = textbox3 if i want to add textbox1 and textbox2 together and display the value in textbox3 WITHOUT creating a button for a command, what do i have to do?
basically, i want the value to appear in textbox3 automatically when i input textbox1 and 2.
I was wondering how I can make textbox1 get divided by textbox2 at the click of button1. The number will go into textbox 3. I was also wondering how I can make the number round up or down. I also want all three text boxes to only accept numbers.show me the code in an easy to read format.
View 2 RepliesI have three textbox textbox1, textbox2, textbox3where
Textbox1.Text = 739
TextBox2.Text = 2.95
TextBox3.Text = Val(TextBox1.Text) * Val(TextBox2.Text) / 100
[code].....
Lets say that I had three TextBox's and they are named TextBox1, TextBox2, and TextBox3, is there a way to do like TextBox And Rand(1,3).Text = Nothing? Something similar to this where you click a button and it will choose at randomly a textbox to clear?I know I could do like Dim Number = Rand(1,3)if Number = 1 Then TextBox1.Text = Nothingend ifif Number = 2 Then TextBox1.Text = Nothingend ifor use else if and such, but I have 12 different textbox's, not three, so, I want to shorten the code, if you could do something like TextBox And Rand(1,12).Text = Nothing that would defenitely be way shorter, can you do anything like that to put together "TextBox" and the number to reference the control? I am not looking to use the full controls list to search for the right control nor to make an array that contains the controls, I just want to reference them without adding extra arrays or searhing for them.

Let's say that you have a texbox labeled TexBox2 and you don't want it to be seen when the program runs because TextBox1 pulls information from TextBox2 and it shows up inside of TextBox1. How would you go about doing this?
