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?

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.

Alex,
The issue that you are seeing where IQConnection Manager is temporarily created in your systray and then disappears is an issue with the IQFeedY active X control. The .NET examples currently use this control, which is why you are seeing the issue. We are currently working to fix this issue.
If you try to run the samples that do not use IQFeedY, you will be able to connect fine. Also, the product name of IQFEED_DEMO is meant for you to use to initially get the apps running. Than, you need to replace it with you product name. Version and Key can always be 1.
Thanks!

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.

Alex,
- Is there a DotNet alternative to using the IQFeedY ActiveX control? Yes, you can use sockets. We do not currently have an example app for this.
- Do you have an expected date for the IQFeedY ActiveX control to be fixed to prevent the IQConnection Manager closing? No, I do not have a date. We are hoping to have it in BETA in the next month or so.
Thanks!

We addressed some additional issues that were found by developers in this release and that has extended the development and testing. We expect it to be released by end of this month (March).

I'm having the same problem, although only on a machine running WinXP Pro, not on one running Win2000 Pro.
Thanks to AlexBellrock for the workaround.
Any update to the release date? It would be good to get this sorted out.

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.
