Compare text

Hello,I am new to vb and I had this question.
I need to read a file that has different fields.
one of the fields has to be uppercase.
what i need to do is a validation if the string is lowercase raise an error.
It only has to be upper.
Thanx for your help

This will check for uppercase:

Code:

---

Dim SomeText As String

SomeText = "HELLO"

If Ucase(SomeText) = SomeText Then
    Msgbox "Uppercase."
Else
    MsgBox "Not uppercase."
End If

---

There is a like function (forgot my vb textbook at school so I can't show you how to use it) sorry

Like is a simple operator.

Code:

---

If String1 Like String2 Then TheyAreTheSame

---

Private Sub Command1_Click()
'this will not work as ucase converts it to uppercase
'and so it will always be uppercase even if it isn't

Dim SomeText As String

SomeText = "Hello"

If UCase(SomeText) = SomeText Then
MsgBox "Uppercase."
Else
MsgBox "Not uppercase."
End If
End Sub

'option like is not an option as you are not
'comparing strings you are merely looking for
'any uppercase characters anywhere in string


'Working Code

Code:

---

Option Explicit

Private Sub Form_Load()

'this would be the var read from file
    Dim myString As String
    myString = "hello"
   
    Dim myLen As Integer  'string len
    Dim iCount As Integer 'var to loop the string

'set to false at beginning
    myAt = False
'get the len for loop
    myLen = Len(x)
   
'loop and check for ascii value of letters in string
    For iCount = 1 To myLen
        y = Left(x, 1)
'if any capital found then alert user and exit sub
      If Asc(y) <= 90 _
        And Asc(y) >= 65 Then
              MsgBox "Capital is included"
          Exit Sub
      End If
  Next
End Sub
