Question

[VB.NET]
Conversion from string ":0" to type 'Integer' is not valid.

Answer 1

I'm making a clock application where the user can set the time, and this is the code I'm using to set the minute to a lower minute:

`Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.click`
`Dim newmin As Integer`
`Dim currmin As Integer`
`currmin = RichTextBox1.Text.Substring(RichTextBox1.Text.IndexOf(":"), 2)` <line with the error
`newmin = currmin - 1`
`End Sub`

The text in the richtextbox is `00:00`, but I'm not sure why the error is occurring. Any thoughts?

Answer 3

Btw, it should be pulling the text from after the `:` and not the `:` itself.

Answer 4

Idk how the strings work in vb. try putting quote marks around the 2

Answer 5

That's not a string. It's specifying the length (of chars) to read.

Answer 6

Answer 8

Well if it's anything like C#, you should have 2, in round brackets.

Answer 9

Not necessary.

Answer 11

Might be an boundary error. Try changing `RichTextBox1.Text.IndexOf(":")` into `RichTextBox1.Text.IndexOf(":") + 1`
