# First build a string that has a preprocessor include
$sbSrc = New-Object Chilkat.StringBuilder
$sbSrc.Append("1`r`n2`r`n3`r`n")
$sbSrc.Append("#include <qa_data/txt/helloWorld.txt>`r`n")
$sbSrc.Append("4`r`n5`r`n")

$($sbSrc.GetAsString())

# sbSrc contains:
# 	1
# 	2
# 	3
# 	#include <qa_data/txt/helloWorld.txt>
# 	4
# 	5

# The qa_data/txt/helloWorld.txt file contains "Hello World!"

$filePath = $sbSrc.GetAfterBetween("#include","<",">")
if ($sbSrc.LastMethodSuccess -ne $true) {
    $("No #include's found.")
    exit
}

$("filePath: " + $filePath)

# Load the contents of the filePath
$sbIncludeFile = New-Object Chilkat.StringBuilder
$sbIncludeFile.LoadFile($filePath,"utf-8")

# Replace the first occurrence of #include <...> line with the contents of the include file.
$sbSrc.ReplaceAllBetween("#include",">",$sbIncludeFile.GetAsString(),$true)

$($sbSrc.GetAsString())

# sbSrce now contains:
# 	1
# 	2
# 	3
# 	Hello World!
# 	4
