i was using this for a custom form that was visual basic inside visual basic (Hb) and this is what the code is:
Public Class Form1
Dim t As Integer
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
If TextBox1.Text = "(Hb window" AndAlso TextBox2.Text = "(document" AndAlso TextBox3.Text = "(text" AndAlso TextBox5.Text = "text)" AndAlso TextBox6.Text = "document)" AndAlso TextBox7.Text = "Hb window)" Then
t = TextBox4.Text
Form2.Label1.Text = (t)
Form2.Show()
End If
End Sub
End Class
but when I type text in textbox4, which I will call "ten" it says that "type ten cannot be converted to integer" could you help?

[@morpheus2953]

You must have entered Dim Number1 As String

[@ken2614]

Try.... Number1=val(Textbox1.text)

[@MuhammadAkbar2127]

Great

[@alvinkoay2961]

what different of value single and double

[@yes-ej2uv]

Alvin Koay Double contains a decimal number/point. Single is a whole number

[@monakapoor43]

plzzz send link before Tuesday plzzz🙏

[@kwstasber9190]

Perfect

[@ghunghroo1]

plzz explain me the concept of comma in i/p & result
hw floating pint variable accepts "," and not "." in result msg box

[@jeffschultz4168]

I'm using 2015 and this does not happen to me, in fact, it parses out commas. This did not make any sense to me, perhaps it is something else such as formatting of the text boxes that is causing this.

[@zuffyzuyyf9618]

ty

[@پروگرامینگبامن]

i don't wanna judging you but the variable must be FLOAT. because if someone wanna use decimal number. he/she could do that.
