  1. Hi, I have built an ActiveX control to interact with my hardware, and intend on using labview to control with ActiveX control and my other instruments. Basically my ActiveX control allows me to scan a USB hub for all hardware attached and then be able to communicate with all the hardware, as I may have mroe than 1 set of my hardware attached that I have under test at any one time. I have a means to do this in a sequential fashion but i'd quite like to exploit Labviews parallel abilities and multithread the communications to the devices, so basically scan my USB hub for connected devices (I have this in my ActiveX control) and then depending on how many are attached make my VI create a "thread" or a "process" for each device attached and then run it... So essentially i will find N number of devices attached and then force my Labview VI to use the ActiveX control in a multithreaded way to talk to them all at the same time (i realise its not true parallel.) Any ideas? Im struggling a bit.... Thanks
  2. Hi I was wondering whether anyone has any experience of creating ActiveX components for use within Labview? I'm pretty new to Labview in general but pushing ahead and quite enjoying it, yea yea so that irrelevant, but hey! I'm pretty competent in both C++ and Visual Basic 6 so can use either of those for creating my ActiveX component. I'm not at work at present so can't log into my NI account to search properly but I was wondering whether there were any quirks to watch out for and ideally if theres any tutorials out there that I can look at to get a better idea of how to push ahead with this more complex element of my project. Thanks
  3. Hi Great Information! Thanks My API is in the form of a DLL, written in C++ and I use simple Windows API functions ReadFile and WriteFile so interact with my driver, Nothing fancy, just functional and easy to get my head around... Also if I want to ship "Labview Compatability" with my board, what would I need to do? just create something like this http://zone.ni.com/devzone/conceptd.nsf/we...625691F0072B2C5, and ship the files? What do NI cards come with to allow when to be used?? thanks I think i'll have to get experimenting! Thanks
  4. Hi, Im very very very new to Labview so excuse my ignorance as my questions is rather daft. I have a custom PCI device, that i have creating a Driver for (driver windows XP based), and also a basic API to communicate with the device and do basic IO. So my question is, with labview if I want to interface my driver (prehaps my API? I dont know how labview deals with this) what do i need to create? What are each of the elements called? I assume theres a means of interfacing with a driver and then displaying the icons in labview? Does anyone have a simple blinking LED/ button press example that I could look at? Tutorials or books? (what the hell do i even search for?!) Currently in our lab with have a few test machines with labview 7.1 and 8 on, i i developed on 7.1 would it have full useability in 8? or if i developed in 8 would it work in 7.1 and earlier versions?? Sorry for all the questions Thank You i2c
