how to check if the user input has a match in my given string
Dim a as string
a = "abc"if the user input in the textbox "erty" the message box will be shown string not found. if the user input 123abc the message box will be string found. how to do that?
Dim userString as string
dim ActualString as string="123abc"
userString =textbox1.text
If userstring=actualstring then
messagebox.show("String Found")
Else
messagebox.show("String not Found")
End IF
You can do it more appropriate with creating its own method, and call it from your main one:
Private Sub MyMethod()
Dim toCheck As String = "someValue"
Dim bChecking As Boolean = Checking(textBox1.Text, toCheck)
If bChecking Then
MessageBox.Show("Values are equal.")
Else
MessageBox.Show("Values are different.")
End If
End Sub
Private Shared Function Checking(input As String, toCheck As String) As Boolean
Return If(input.Equals(toCheck), True, False)
End FunctionIf understand correctly you need to identify if 'abc' is part of the inserted string.
this can be done be using the existing functions of vb.net like this
Dim SearchString as string ="abc"
Dim userstring As string= textBox1.Text
If userstring.contains(SearchString) then
messagebox.show("String Found")
Else
messagebox.show("String not Found")
