There are so many options available in labwindows CVI I am not sure what you need that it doesn't have, there is most likely something available that will fit your needs, also you are able to add programming behind anything making it an extremely customizable tool. What specifically are you trying to do and maybe we can get it to work with existing functions.
Thanks,

Thank you very much for your reply. Actually we are thinking of customizing several controls. One of them is the ring gauge, which is used usually as a vehicle speed indicator. We need some client requested features on that.
I looked for a while but I did not find an option to customize this control. Of course it is possible also to make a Active-X control from ground-up. But I am wondering if there is something from NI to make the job easier.
Well if you need to make a completely original control than you are stuck making something external and linking it. You can make an activeX as you mentioned or you could create something in C++ or C# and link it as a dll. Perhaps you are unable to give out details because of confidentiality but what type of function do you want the gauge to do? You can look into the SetCtrlAttribute function which will allow you to change the look (colors, text, values, size) etc.. throughout execution of your program, also if it is the value that needs to be special than you can have it update based off of c code which could contain any formula etc.. Give more details if you can if not I'm afraid you might be stuck using an external feature.
