This function does a case sensitive search for an occurrence of a substring in a string. It returns the substring if it is found. Otherwise it returns null(""). It was created by slightly modifying [[StrRep]]
== How To Use ==

=== Syntax ===

; Single command
: This is by far the easiest way to use StrContains.
<highlight-nsis>
${StrContains} $0 "Dirt" "Dirty deeds done dirt cheap"
StrCmp $0 "" notfound
MessageBox MB_OK 'Found string $0'
Goto done
notfound:
MessageBox MB_OK 'Did not find string'
done:
</highlight-nsis>

; Push/function call
: For when you're used to NSIS :)
<highlight-nsis>
Push "It's a long way to the top (if you wanna rock n' roll)"
Push "long"
Call StrContains
Pop $0
StrCmp $0 "" notfound
MessageBox MB_OK 'Found string $0'
Goto done
notfound:
MessageBox MB_OK 'Did not find string'
done:
</highlight-nsis>

; Usage
: ${StrContains} "$result_var" "Needle" "Haystack"

=== Parameters ===

; $result_var
: Variable will contain the "needle" value if the needle is found in the haystack. Otherwise, it will contain null ("").

; Needle
: String to search for.

; Haystack
: String to search.

=== Example ===

<highlight-nsis>
${StrContain} $0 "just " "This is just an example"
;$0 = "just"
</highlight-nsis>

<highlight-nsis>
${StrContain} $0 "missing " "This is another example"
;$0 = ""
</highlight-nsis>
