All -
I've made some fixes to the COM interface, and want to know what other items
are necessary.
The fixes are:
The company description now matches the description in the charts.
The company info object now returns the correct information for the irl
index value.
Enhancements:
There is a new price object - price2 - that contains some additions :
[id(12), helpstring("method OpenInterest")] HRESULT OpenInterest([in] long
lDay, [out, retval] VARIANT* pValue);
[id(13), helpstring("method GetMaxInRange")] HRESULT GetMaxInRange([in]
QP_PRICETOKEN whichField , long StartDay , long EndDay , [out] DOUBLE
*dValue , [out,retval] BOOL *pOK);
[id(14), helpstring("method GetMinInRange")] HRESULT GetMinInRange([in]
QP_PRICETOKEN whichField , long StartDay , long EndDay , [out] DOUBLE
*dValue , [out,retval] BOOL *pOK);
[id(15), helpstring("method GetMfJulianDate")] HRESULT GetMfJulianDate([in]
int month, int day, int year , [out,retval] int *JulDay);
[id(16), helpstring("method SetMfJulianDate")] HRESULT SetMfJulianDate([in]
int JulDate, [out] int *Year, int *Month , int *Day);
[id(17), helpstring("method SetPeriod")] HRESULT SetPeriod([in] BSTR
Period);
[id(18), helpstring("method GetPeriod")] HRESULT GetPeriod([out,retval] BSTR
*Period);
[id(19), helpstring("method Change")] HRESULT Change([in] long lDay, [out,
retval] VARIANT* pValue );
The additions would be helpful for those who want to write their own
programs in VB using the com interface.
Let me know what other items you want in the interface, I can add your
changes now.
Thanks,
Gary

Let me make this a little easier to read
The com enhancements are:
OpenInterest Returns the open interest for commodities
GetMaxInRange Get the maximum open,high,low,close,volume or open
interest in a range
GetMinInRange Get the minimum open,high,low,close,volume or open
interest in a range
GetMfJulianDate Returns a monday-friday julian date value from
month,day,year
SetMfJulianDate Returns the month,day,year from a monday-friday
julian date
SetPeriod Sets the period - (daily/weekly) of the data
GetPeriod Gets the current period
Change Returns the net change for a day from the previous day
There is also a days to load parameter on the load data call
These will be available from VB or Excel etc.
