ENUM Values for Pull Down menu in MT4

I was trying to create a pull down menu based on enum and the discussion here http://docs.mql4.com/convert/enumtostring

However a few of the values are symbols for futures and are like this

enum SymbolToTrade
{
SelectSymbol, // Select Symbol
#NAS100_H6, // Nasdaq100 Futures H6
#DJ30_H6, // DJ30 Futures H6
EURUSD, // EURUSD FX
USDJPY, // USDJPY FX
};

MT4 doesn't like the # sign, the others are ok, any work arounds for this?

Hello Pipologist,

Use a sideways array instead to translate the ENUM values to the appropriate strings:
Inserted Code
enum SymbolToTrade
{
SelectSymbol, // Select Symbol
NAS100_H6 = 0, // Nasdaq100 Futures H6
DJ30_H6 =1, // DJ30 Futures H6
EURUSD = 2, // EURUSD FX
USDJPY = 3, // USDJPY FX
};
extern SymbolToTrade SymbToTrade;
string aSymbols[] = {"#NAS100_H6","#DJ30_H6","EURUSD","USDJPY"};
Comment("chosen value:"+aSymbols[SymbToTrade]);

Regards -- Aron

thank you. for now I've resigned myself to just manually inputting the symbol selection, but will refer back to this when I have more time and mental energy to give it a try
