How do I set a textbox to a number value such as an Integer?


There are several ways of going about this... The most basic way is to do a simple conversion, ike so:

Cint(textbox1.text)

This code is just used anywhere you would usually place

Textbox1.text

Rob =]

WebBrowser1.Navigate(NavBox.Text)

This one is not hard, all you have to do is use the KeyDown event instead... for example

Private Sub Form1_KeyDown(ByVal e As System.Windows.Forms.KeyEventArgs)Handles Me.KeyDown

If e.keyvalue = keys.enter then

WebBrowser1.navigate(NavBox.text)
End if

Have Fun!

HELP!!!! HELP!!! HELP !!!! How do I code the + , - and * buttons for a calculator? How do I code the text boxes for the numbers/text box,.. and for the 'sum' text box so it's cleared every time you put a diff. number in to add an subtract? Do you take out all the exisiting code that's between the Private Sub and the "end" ????? or do you leave in the existing code and add to it whatever's supposed to be IN there,.. and what IS supposed to be in there ?! our text book is NO HELP and Microsoft's help is NO HELP!!!! UUUUGGGGGH!!!!!

First of all, when you deal with textboxes and +/- you need to make them into integers, which is done by replacing TextboxAnswer.text or ButtonOne.text in your code with Cint(TextboxAnswer.text) etc.

Also, you need to place the following code in the event for the Equal button press

TextboxAnwer.text = ""

that clears it.

If you want, just before that line, you could include a variable to make the original sum hang around:

Public answer as integer = 0

Private Sub Equals_pressed(byval e as system.eventargs)Handles Equals.pressed
Answer = CInt(TextboxAnswer.text)
TextboxAnswer.text = ""
End Sub

Yes it may sound sad but how do i fix the "end statment expected" error?

Try defining your variable value within the line such as:

Dim VariableName As Integer = TextBox1.Text

I have a form with a disabled button and a normal text box. I want to make it so when the text box says something the button becomes enabled. For example if the text box says password then the button would become enabled

Define your password first

Public Password as string = "Password"

Then in the TextChanged event for the TextBox

Private Sub TextBox_TextChanged(ByVal e as system.eventargs) handles textbox1.textchanged
If textbox1.text = "Password" then
Button1.enabled = true
else
button1.enabled = false
end if

Simple form with 2 buttons
First button starts code running (say updating the value in a text box)
Second button stops the code
Problem I have is that form has lost focus so how do I effectively allow other things to happen while code runs - it's not multi-threading is is?
Thinking about it I could have a seperate process in another app to change a value which the running code tests for but that's very cumbersome!

Heres a basic Layout to do this:

Ingredients:
2 Buttons (1 Says Start Other Says Stop)
1 Textbox or NumericUpDown
1 Timer

Code:
Timer 1:

PrivateSub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick 

NumericUpDown1.Value = NumericUpDown1.Value + 1
Textbox.Text = TextBox1.Text + Val(1)

EndSub

Start Button:

  
PrivateSub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Enabled = True

  

  
EndSub

Stop Button:

PrivateSub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Timer1.Enabled = False

EndSub

Very Simple

VeeBeer

Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
TextBox1.TextChanged
    If TextBox1.Text = "InputText" Then
        Button1.Text = "InputText"
        Button1.Enable = True
        Button2.Text = ""
        Button2.Enabled = False
    Elseif TextBox1.Text = "InputText" Then
        Button1.Text = ""
        Button1.Enabled = False
        Button2.Text = "InputText"
        Button2.Enabled = True
    End If
End Sub
