How to use DLLs ?

["Philippe_Lhermie" <philippe_lhermie@xxxxxxxxxxx>]

Hi All,

I tried to use a DLL function as explained in the TSY2K developer's kit.

I created a Signal using a slightly modified Omega's example :
{#DLL001}

DefineDLLFunc: "USER32.DLL",bool,"MessageBeep",int;

If Open > Close  or Open < Close then MessageBeep(0);


After I inserted this signal into a system with the systemBuilder and I
plotted it into a chart.

The results are :
It beeps endlessly and TS is stuck during 1 minute, even if there's no new
quotation.
Furthermore, It stops without my intervention and after it works fine : it
generates a beep each 5 minutes on a 5 min bar chart.


1. Could you explain to me why ?

2. How can I find the useable DLLs with TS2000 ?

3. How can I know the functions available in one DLL ?
For example, what else can we do with the USER32 library ?



Thanks,


Greetings from Paris
