Sample video streaming with datasockets not working

[rogelio]

We're trying the VB sample code in http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3E90B56A4E034080020E74861 but we're getting a visual basic error 30222: "newer NI-IMAQ version needed" in CWIMAQ1.LoadInterfaceDefaults.
We have installed IMAQ Vision 6.0 for Measurement Studio, and NI-IMAQ for IEEE 1394 for the camera.
Any ideas of what could be happening here?

Hello,

Thank you for contacting National Instruments. You mentioned that you had NI-IMAQ for IEEE 1394 installed. Do you also have an NI IMAQ board and the NI-IMAQ driver installed? If so, which board and what version of the NI-IMAQ driver?

The CWIMAQ ActiveX control is based on the NI-IMAQ driver and requires an NI IMAQ frame grabber board. NI-IMAQ for IEEE 1394 will not work with the CWIMAQ control. Unfortunately, NI does not currently offer a similar ActiveX control for the 1394 driver.

I tested this example with NI-IMAQ 3.0, IMAQ Vision 6.0, and a PCI-1409, and the program behaved as expected. Note that NI-IMAQ 2.5 or newer is required for this example.

If you do have an IMAQ board and the NI-IMAQ driver, let me know the versions so I can conti
nue to investigate the error you are receiving.
