How do you make something happen if a number is less than zero.
If Number < 0 Then
Break // Happen
// Go on, making nothing happen
Dim i as integer
If i < 0 then msgbox “Too low”
You may also want to look at computed properties.
They are the answer if your question means something like
’ When the user sets the value of dfBankAccount to zero, then I want to send an email’
What you do is create a computed property (maybe called dfBankAccount), with a Get and a Let pair of methods.
Inside the Let method, if the value being set is zero, you can call another method, send an email, throw up a messagebox, or anything you like.
That doesnt happen simply by setting a normal integer variable to zero.
What I made subtracts from a number when you click a button but I don’t want some one to be able to make it go below zero
Then in the action event before you return put something like this:
If myValue < 0 Then
myValue = 0
Another way would be
myValue = Max(0, myValue)
I tend to do the Max option here. Drives my coworkers nuts as they prefer an explicit conditional apart from assignment.
I just figured it out by putting in Cash.Text.Val <0
