StrComp function- Limited Case sensitive string comparisons? 1

[irethedo]

I have a question about Case sensitive string comparisons...

I have a form with a text box called OldPWD that I entered "Test" into and with the code below I am
comparing this to "test" and the result is 0 which indicates that they are equal.

If I enter "TEST" (all caps) into the OldPWD text box then I get a result of -1

I am getting the impression that the strComp function can only compare case sensitivity text
as either fully upper case versus fully lower case...

I first tried " If OldPWD <> "test" and that compare also resulted in True...

Is there a way to test for any differences in case sensitive letters between two strings.

Private Sub Command3_Click()
Dim stcmp As Integer

stcmp = StrComp(Me.OldPWD, "test", 0)

End Sub

thanks

If Me.OldPWD = "test" Then
    MsgBox "Your OldPWD is 'test'"
Else
    MsgBox "Your OldPWD is NOT 'test'"
End If

Hi Andy

I just tried your code, and found that if "Test" is placed in Me.OldPWD then the Message Box= "Your OldPWD is 'test'"
and if if "TEST" is placed in Me.OldPWD then the Message Box= "Your OldPWD is 'test'"

I am looking for a way that can determine if each letter in a string matches the case...

thanks

I think you are interpretting -1,0 incorrectly. That is not true and false.

If StrComp returns
string1 is less than string2: -1
string1 is equal to string2: 0
string1 is greater than string2: 1
string1 or string2 is Null: Null

Test

Public Sub Compare()
  Dim x As String
  Dim y As String
  Dim z As String
  x = "Test"
  y = "TEST"
  z = "test"
  Debug.Print StrComp(x, y, vbBinaryCompare)
  Debug.Print StrComp(x, z, vbBinaryCompare)
  Debug.Print StrComp(y, z, vbBinaryCompare)
  Debug.Print StrComp(x, x, vbBinaryCompare)
End Sub

resutlts:
1 'Test > TEST
-1 'Test < test
-1 'Test < test
0 ' Test = Test
All results are correct

MajP, could you check my logic, please?

Works as I expected at my end....

Andy. You are both right depending what is at the top of your module

option Compare Database

Public Event HelloWorld()
Public Sub Command5_Click()
  Debug.Print Me.TextOne = "Test"
End Sub

True

Option Binary or no option you get false.
You have nothing or binary and he has compare database.
