Hmm I just noticed that the NI Visa Server didnt even install. With my frustration I was going ahead in reinstalling LabVIEW until I noticed that some components did not install for some odd reason. Sorry for the inconvenience.

Hey all, I am having trouble with LabVIEW recognizing my communications ports on my notebook computer. I have one serial com port (COM1) built into the dock for my notebook as well as a USB to Serial connector (COM4). Both are working properly and are detected by Windows under Device Manager. Unfortunately for me, the VISA Find Resource tool does not recognize any of my communications ports, and with all VISA Open connections there isn't anything in the dropdowns. Has anyone else had this problem? Hoping it is just a quickfix in LabVIEW. Thanks in advance.

Thanks a lot for your help guys. I am going to play around with it a bit because I am looking to have the user mark the boolean in runtime and have the ability to turn on and off whenever the user pleases. Thanks again.

Alright last question on this topic which I seemed to have butchered. I am trying to incorporate a boolean control array along with the listbox where each control corresponds to the specific index in the listbox. Idealy I would like the array to scroll along with the scrolling of the listbox, so the controls line up so to speak. I didn't have any luck with finding events or properties that can be manipulated. The only other option I tried was using an array of clusters, where each cluster has some data (like a numeric or string) and the boolean control, in this case a checkbox. However what I found was that for one thing, I would have to play with the pixels of course to get the original question on clicking on an array to work, and another thing I found that I was unable to check off the boxes in the array, they simply acted as indicators. Any suggestions? Attached is the listbox vi and the array of clusters vi. edit: when continuously playing with the array of clusters option, i found that using the pixels as a tracker for the clicks, if i 'scroll' (ie updating the index), and complete a cycle for example in scrolling, if i click on the first element in the new appearing cycle, it gives me the first element of the entire array, so I guess for my application the listbox would be ideal if I can incorporate the boolean checkboxes along with each row.

haha wow... I think I tried everything else but that. Thanks again.

haha well I guess if you want to get rid of a couple of extra wires edit the control. I have been having so much fun with listboxes, that I've filled them totally up, however just can't seem to figure out how to make sure I have a 'clean' listbox when I start my program. Attached is a simple insert, if someone can tell me how on earth to clear it (because I can't seem to find any property nodes, and if I have a list of 500 items, does it make sense to delete all the rows each time i start up...)

Hey thats not a bad idea, thanks! Guess you got to be a little creative :thumbup:

Thanks a lot for the input guys. Both the listbox and the array will come in handy. One thing I like about the listbox is that it has a vertical scrollbar. Is there any way of inputting a scrollbar on an array?

Hey all, I am a long time reader, first time poster (not really experienced). I was hoping someone can help me out with this problem. Given an array of say ten elements, all being numeric for example, I want to be able to say click (or double click) on for example the 5th element and bring up another window with information solely for that element. I tried playing with the Events Structure however I can only select the entire array to perform the event, not just a single element in the array. Is there a way to I guess, track where the mouse clicked so that I can perform actions pertaining to the desired element? Or another 'proper' way of doing what I am looking to do? Hope I made sense... Thanks. Rohit
