"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip
"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

"I just wanted to let you know how fast and easy I found it to integrate IQFeed into our existing Java code using your JNI client. In my experience, such things almost never go so smoothly - great job!" - Comment from Nate
"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim
"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

I am unable to use DTN from my java app on
vista x64. When it attempts to load the library iq_jni.dll
i get the message:

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Program Files (x86)\DTN\IQFeed\iq_jni.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

iq_dni.dll is a 32bit dll. It is not possible to load a 32bit dll from within a 64bit assembly without doing quite a bit of work to make it think it is loading a 64bit dll instead of a 32bit.

We do not currently have a 64bit version of iq_jni.dll.

As a result, you will need to either continue to run your app as a 32bit assembly or create a 32bit assembly to launch the feed before running your 64bit assemply.

well that IS a bummer.

Don't you think you should make an iq_jni_64.dll?

usually this requires merely a recompile.
