Help with strings

[Axle]

I'm writing a visual C++ .Net Console application, and I have it almost finished. The object is to create arrays and populate them with stock symbols, amount of shares for each stock, purchase price of each share, and to generate a random price for the current price. Then I am to calculate the total purchase value of each stock, then the current value of each stock. Then I am to output each stock symbol, the purchase value of each stock, the current value of each stock, and the difference (profit/loss) of each stock to a MessageBox. The problem enters when I try to build a string using a build string method that returns a concatenated string (concatenated within a for loop local to the BuildOutputString method), and then try to assign the returned string to a string variable local to the main method.

// Stocks.cpp : main project file.

#include "stdafx.h"
#include <Windows.h>
#include <stdio.h>
#include <string>

#using <System.dll>
#using <System.Windows.forms.dll>

using namespace System;
using namespace System::Windows::Forms;


const int NUMSTOCKS = 3;

//void GetValue( array<int ^> ^gcnew[], array<double ^> ^gcnew[] );
array<String ^>^ AddSymbol();
array<int ^>^ AddShares();
array<double ^>^ AddPurchasePrice();
array<double ^>^ GetCurrentPrice();
array<double ^>^ GetPurchaseValue( array<int ^> ^shares, array<double ^> ^prices );
array<double ^>^ GetCurrentValue( array<int ^> ^shares, array<double ^> ^prices );
String ^BuildOutputString( array<String ^> ^symbols, array<double ^> ^pValues, array<double ^> ^cValues );


int main( array<System::String ^> ^args )
{
	array<String ^> ^ stockSymbols = AddSymbol();
	array<int ^> ^ stockShares = AddShares();
	array<double ^> ^ purchasePrice = AddPurchasePrice();
	array<double ^> ^ currentPrice = GetCurrentPrice();
	array<double ^> ^ purchaseValues = GetPurchaseValue( stockShares, purchasePrice );
	array<double ^> ^ currentValues = GetCurrentValue( stockShares, GetCurrentPrice() );
	String ^output = BuildOutputString( stockSymbols, purchaseValues, currentValues );
	

	//String ^str = &stockSymbols[i];
	//MessageBox( NULL, &stockSymbols[i], "Stocks", MB_SETFOREGROUND );
	MessageBox::Show( output,
			"Stocks",
			MessageBoxButtons::OK,
			MessageBoxIcon::Information );
		
	return 0;
}

array<String ^>^ AddSymbol()
{
	array<String ^> ^localArray = gcnew array<String ^>( NUMSTOCKS );
	localArray[0] = "KWK", localArray[1] = "SFY", localArray[2] = "GM";

	return localArray;
}

array<int ^>^ AddShares()
{
	array<int^ > ^localArray = gcnew array<int ^>( NUMSTOCKS );
	localArray[0] = 10, localArray[1] = 10, localArray[2] = 10;

	return localArray;
}

array<double ^>^ AddPurchasePrice()
{
	array<double ^> ^localArray = gcnew array<double ^>( NUMSTOCKS );
	localArray[0] = 36.67, localArray[1] = 43.09, localArray[2] = 31.55;

	return localArray;
}

array<double ^>^ GetCurrentPrice()
{
	Random ^randomDouble = gcnew Random();
	array<double ^> ^localArray = gcnew array<double ^>( NUMSTOCKS );

	for ( int i = 0; i < localArray->Length; ++i )
	{
		localArray[i] = randomDouble->NextDouble() * 100.00f;
	}

	return localArray;
}

array<double ^>^ GetPurchaseValue( array<int ^> ^shares, array<double ^> ^prices )
{
	array<double ^> ^localArray = gcnew array<double ^>( shares->Length );

	for ( int i = 0; i < shares->Length; ++i )
	{
		localArray[i] = ( ( Convert::ToDouble( shares[i] ) )  * ( *prices[i] ) );
	}
		
	return localArray;
}

array<double ^>^ GetCurrentValue( array<int ^> ^shares, array<double ^> ^prices )
{
	array<double ^> ^localArray = gcnew array<double ^>( shares->Length );

	for ( int i = 0; i < shares->Length; ++i )
	{
		localArray[i] = ( ( Convert::ToDouble( shares[i] ) )  * ( *prices[i] ) );
	}
		
	return localArray;
}

String ^BuildStringOutput( array<String ^> ^symbols, array<double ^> ^pValues, array<double ^> ^cValues )
{
	String ^localString;
	
	for ( int i = 0; i < symbols->Length; ++i )
	{
		double change = ( *pValues[i] - *cValues[i] );

		localString = String::Concat( localString,
					symbols[i], 
					"/n", pValues[i]->ToString(),
					"/n", cValues[i]->ToString(),
					"/n/nChange In Value: ", Convert::ToString( change ) );
	}

	return localString;
}

and the error:

Any help is greatly appreciated.

Btw, I'm using VS2k5 with WinXP

Fixed it, was a name mismatch between the prototype and method signatures. Figured it was something simple, could have sworn I checked that though.
