Test if 4 variables are equal

4 posts in this topic

#1 ·  Posted (edited)

Hi all,

I'm just trying to figure out the best way to check if 4 variables are equal for error checking purposes.

I know I can test each of the combinations like this

if $var1 <> $var2 and $var1 <> $var3 and $var1 <> $var4 and $var2 <> $var3 and $var2 <> $var4 and $var3 <> $var4 then

but I am curious how programmers would format it to be more efficient.

Thank you

Like this

If $var1 = $var2 And $var1 = $var3 And $var1 = $var4 Then   ;all the vars are equal
If ($var1 = $var2 And $var1 = $var3 And $var1 = $var4) = 0 Then ;any of the vars are not equal. - you can use a "NOT" operator over here even.

My code:

PredictText: Predict Text of an Edit Control Like Scite. Remote Gmail: Execute your Scripts through Gmail. StringRegExp:Share and learn RegExp.

Run As System: A command line wrapper around PSEXEC.exe to execute your apps scripts as System (LSA). Database: An easier approach for _SQ_LITE beginners.

MathsEx: A UDF for Fractions and LCM, GCF/HCF. FloatingText: An UDF for make your text floating. Clipboard Extendor: A clipboard monitoring tool. 

Custom ScrollBar: Scroll Bar made with GDI+, user can use bitmaps instead. RestrictEdit_SRE: Restrict text in an Edit Control through a Regular Expression.
