Question

In my code i want to use if condition. In which i want to use “OR” around 18 times.
Like for e.g.

If a="something" or a="something" or a="something" or.........(up to 18 times)... then
  'do nothing
else
  'do action
end if

[Note : value of a is changing in For loop every time]
so i just want to ask does there any limitation in IF for using OR in limited times.
OR is there any other better way to do the same.

Thanks

Answer 1

As far as I know, there is no limitation when using OR this way.

Yet, you may consider alternative ways of coding this.

Negating a condition using Not

First, if you do nothing in the first case, then consider using the Not statement:

If Not True Then
'do somethin
'no else
End If

Consider using Select Case

Second, if you are checking the very same variable, you could either consider using a Select Case but it doesn’t seem appropriate in your case if you have only one case.

Try to use a search

Eventually, if you are checking strings, you could probably better use a search within an array (with Application.Match if you are within Excel or .Contains) or within a String using Instr.

Using a collection or a dictionary

[EDIT] Another very good way to handle this would be to use the Dictionary Structure of VBA and check if a exists (see MSDN for some information).
