Author	Topic: RegisterClientApp() bugs in IQ32.dll (2 messages, Page 1 of 1)
sasha -Interested User- Posts: 54 Joined: Jul 21, 2004	Posted: Nov 2, 2004 08:28 AM Msg. 1 of 2 Having both DTN.IQ and IQFeed API installed seems incompatible. I am using the IQ32.DLL located in the "C:\Program Files\DTN\IQFeed\" directory for my application development/API. (IQ32.DLL file version is 3.7.0.0 with size 98,304 bytes). If DTN.IQ is running and logged on, calling RegisterClientApp() returns true (for success). However, a MessageBox pops up with the message "Error: a version of IQConnect is already running". This is a problem because the call the RegsiterClientApp() returned true but in fact it should have returned false - a failure. And the callback doesn't get called so there is no IQ32 status returned. Since we are relying on this status callback it should always work. I think RegisterClientApp() should block until a successful registration is confirmed. I cannot use the IQ32.dll in the "C:\Program Files\DTN\DTN.IQ\" directory after calling RegsiterClientApp() it pops up a message box error "Error: Cannot find IQConnect.exe" and then causes an unidentified exception. In addition there is no SetAutoLogin() function exported. P.S. Does this mean it is impossible to run a third party application with DTN.IQ client applications running?

Again, this is something we will be supporting much better in the future. Jay Froscheiser DTN Market Access, LLC.
