Android Question [SOLVED] Help with an IF clause

techknight · Jan 27, 2021

Now, I suppose I am getting more stupid as I age, but I must be missing the obvious.

This works if its either one of the string matches, which is a desired operation:

B4X:

If VarD = "GqrNrmcZyTvqG67B" Or VarD = "E4YhdpBsQ88jWR6p" Then

However, I am trying to do a return if VarD does not contain either one of those, like this:

B4X:

If VarD <> "GqrNrmcZyTvqG67B" Or VarD <> "E4YhdpBsQ88jWR6p" Then Return

But, it doesnt work. it returns regardless if VarD has either one of the strings.

I want it to work like this: If VarD doesn't contain either of those strings exactly as they are, then return.

Thoughts?

Shouldn't it be AND instead of OR ?

and, not or.

Use of Not

B4X:

    Dim VarD As String = "GqrNrmcZyTvqG67B"
    
    If Not(VarD = "GqrNrmcZyTvqG67B" Or VarD = "E4YhdpBsQ88jWR6p") Then
        Log(True)
    Else
        Log(False)
    End If

Time ago I had problems with such logic clauses and spent some neurons to remember NOT(a OR b) is equal to NOT(a) AND NOT(b) and similar ones...

    End If

Never even thought about that.

Thanks

VarD.Contains("GqrNrmcZyTvqG67B") Or VarD.Contains("E4YhdpBsQ88jWR6p")

yes, sometimes we have a positive logic and never a negative.

The problem with Contains, is I dont know if there were extra characters at the beginning or end, would it satisfy. the string needs to contain "exactly" that. nothing more or less or extra.

Your code works great, but I wanted to be a little fancy like Erel would do sometimes:

B4X:

Log(oparra("GqrNrmcZyTvqG67B"))

B4X:

Sub oparra( Vard As String) As Boolean
    Return Not(Vard.Contains("GqrNrmcZyTvqG67B".trim) Or Vard.Contains("E4YhdpBsQ88jWR6p".trim))
End Sub

or this:

B4X:

Sub oparra( Vard As String) As Boolean
    Return Not(Vard = "GqrNrmcZyTvqG67B" Or Vard = "E4YhdpBsQ88jWR6p")
End Sub

Sub oparra( Vard As String) As Boolean Return Not(Vard = "GqrNrmcZyTvqG67B" Or Vard = "E4YhdpBsQ88jWR6p") End Sub

I thought about it but was guided by the code of the post.
