I am a developer at Bellrock Capital and am getting started with the IQFeed API for DotNet.

One function we require is to retrieve a history for a given symbol (e.g. last 10 days for MSFT). From the documentation, it seems I need to use a HistoryLookup object (from DTNHistoryLookup.dll) - however, when I try adding this to my Visual Studio toolbox, this does not give me any components - possibly this is not a DotNet compatible control?

Thanks for your help,

Alex.

Replying to this one myself after some further research ...

The HistoryLookup object cannot be used as a drag and drop control from Visual Studio designer but can be used successfully in DotNet by adding a reference to DTNHistoryLookup and using code such as the follows (here in C#) :

// connect HistoryLookup object
m_historyLookup = new HistoryLookup();

// hook up HistoryLookup events
m_historyLookup.DayCompleted += new _IHistoryLookupEvents_DayCompletedEventHandler(m_historyLookup_DayCompleted);


private void m_historyLookup_DayCompleted(int noDays_, object objTime_, object objOpen_, object objClose_, object objHigh_, object objLow_, object objVolume_)
{
// handle results here
}

Alex,

FYI - We provide a COM interface, and a socket interface. You may use which ever one you are more comfortable with.

Thanks!
