UnexpectedCastException was uhandled [solved]

I am working on a simple spammer, but I keep getting this error when making the "Set Interval"

[highlight=vb.net]
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox5.Text = ("") Then
MsgBox("Please, put a valid number value", MsgBoxStyle.Critical + MsgBoxStyle.OkOnly, "ERROR")
Else

End If
Timer1.Interval = TextBox1.Text * 1000

End Sub[/highlight]

The Timer1.Interval = ((TextBox1.Text) * (1000)) is giving the error.

isn't it just

Code:

timer1.interval = TextBox1.Text * 1000

It debugs fine. But when I put a number in the text box under interval, it closes the application and gives a error.

nvm
Got teamview ???

You're implicity casting a String to an Integer.

Code:

Timer1.Interval = CInt(TextBox1.Text) * 1000

It would be better to use a NumericUpDown control otherwise if someone puts letters into text box the program will shit itself.

I just edited it and I still get the same error.

try...

[highlight=vb.net]
try
Timer1.Interval = CInt.parse(TextBox1.Text) * 1000
catch
msgbox("please enter numbers only")
end try
[/highlight]

[/highlight]

@master131

I added a NumericUpDown control instead. What code do I need to put in?

Thank you, It works perfectly now. Can you tell I'm new to visual basic?

Obviously. You should attempt to read the documentation (at least the properties) of any control you intend to use. MSDN is particularly helpful in this regard. It will make your life a lot easier once you start understand the capabilities of the controls you are using.

Marked Solved.
