StrCmp or ${If}

I mean CONTAINS,not equals...

You can use the WordFind macro from the WordFunc Header (NSIS user manual E.3)

${WordFind} "$sample" "MSG" "#" $R0

${If} $R0 > 0

     DetailPrint '"MSG" found in string $sample ($R0 times)'

${Else}

     DetailPrint '"MSG" not found in string $sample'

${EndIf}

You can use WordFindS to search case sensitive if needed.
