Another update from myself (original poster).
This issue now appears to be resolved since updating to the new version of IQFeed 2.3.0.3 (beta).
Thanks,
Alex.
No update from my side - we are still making do with the workaround here, but would be very interested to use the fix once available ...
Alex.
Thanks - I'll hold out for the fix for the COM version.
Alex.
Thanks for your response.
Please can you let me know : - Is there a DotNet alternative to using the IQFeedY ActiveX control? - Do you have an expected date for the IQFeedY ActiveX control to be fixed to prevent the IQConnection Manager closing?
Alex.
An update on this question after some further research ...
I can still only connect using DotNet if I have established a connection first using one of the example tools - otherwise the IQ Connection Manager is created temporarily in my system tray and then immediately disappears, resulting in errors.
I have also found that disconnections are only successful if I connect using product name IQFEED_DEMO. However, if I connect using our own product name, then disconnections fail ("clients connected" do not drop in IQ Connection Manager and no system disconnect messages are received). The only way to successfully terminate the IQFeed connection here is to terminate my process.
Please can you confirm how I can connect / disconnect in a more reliable manner and what connection parameters (name, version and key) I should use?
Thanks,
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.
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.
I am a developer at Bellrock Capital and am getting started with the IQFeed API for DotNet.
I am having trouble running the two example DotNet applications (csharplevel1com and vbdotnetlevel1com). In both cases, a connection box comes up to connect to IQFeed, but then no data comes back when making requests through these applications.
I have found the workaround is to use another one of the example tools first (e.g. IQExplorer / VC++ examples) which connect successfully and launch the IQ Connection Manager in my system tray - then when I run the DotNet applications, I get the initial error "A client application already exists with that name", after which everything seems to work.
How can I get the DotNet examples to work independently without loading up these other tools first?
Our product name is as sent to us in your e-mail, together with a version of "1.0" and a key of "1.0" - please let me know if these values are correct?
