I had posted a long time ago about a bug that crashed Labview. Tech support was all over it. I ran several tests to attempt to isolate it and provided some samples. I just installed the latest 2009 version and wanted to see if they fixed some of the problems I had found. Good to know the bugs are still there. If you run this with your 2009, make sure you save all your work first as Labview will crash and then close. Cursors in digital graphs don't mix I guess... Simple Digital Waveform Graph0.vi

Installed the latest version of Labview (09). I had been using 8.5.1. I left the older version install, just in case. First thing I noticed was the 09 version did not import all the settings I made in the previous version. So it has all these new wizz bang features enabled again. Is there a simple way to just import the settings from my previous version? Why isn't the software smart enough to do this for me anyway? It took an act of God to find how to change all the settings in the old version to something more pleasing to me. Do I have to call on him again?

After blowing the whole install away, I tried it all from scratch again. Both VISA and GPIB work now from the installer. A glimmer of hope.. I have been asked by three other people how to use the builder with the new tools. In all cases, they gave up and installed Labview. So I don't feel so bad.

That is the menu I am looking at. When I expland the My Computer, I do not see the entire computers drives, just the top level VI. I thought maybe I could add it under the Dependencies, but I don't see any add feature. I'm sure it's very simple to add it, I just don't understand how. Maybe you have to use some other program to add. Seems poor at best from an ease of use standpoint. Time to break out the books I guess. Ah ha!! You have to add it to using the higher level Project Explorer menu. If I select the lvproj, then select the Project and Add, it will not let me add it. However, if I select My Computer, then right click, or select the Add, it then allows me to add. I guess my computer is not considered the Windows My Computer as its been forever. Easy enough after you know how but not user friendly. I'll blow away all the installs on my test PC and see if I can get everything to work now.

I wish the new versions of Labview were just that simple to include what I want. How do I even add the INF to the project? I can't find anything in this new tool. After making a project file, I go under the installer properties and Select source files. I would expect to be able to go to any location to select the files I want to add and add them. The tool will not let me. I have the VISA runtime selected as well as NI-488 under additional installers. In the case of the GPIB, I use the ENET1000. It's a similar problem where I seem to have to install the full version Labview, then run the GPIB wizard to find the ENET1000 to get it working. A whole different problem I am sure. I am amazed with as much as Labview has changed that tools like the builder are not smarter and more user friendly.

I am using Labview 8.5 and would like to use the application builder. In this case, the PCs I want to target are clean installs and have no Labview support. So, I want to make a Project Installer. The program runs on an embedded PC and talks to a custom card through a CPCI bus. Rather than write all the low level code in C, the VISA calls were used. Very simple and it works fine. The NI-VISA Diver Wizard was used to create the files. The problem I am having is that I don't see a way to include this during the build. What I end up having to do (yea, this was a total desperate attempt as I needed to get it working) was after I installed the project, I installed a full copy of Labview on the target PC without a license, then ran the wizard with the INI file. In the past I was just mirroring the disk drives so everything was being copied. I have licenses for the images but now I want to use this outside the building so need a better solution. Is there a step by step guide to get around this. Thanks for any help.

If that is true, where is the +/-? Are you trying to preload (offset the force) the cell so is goes through the 0 point? If so, why? What sort of resolution, accuracy and repeatablity are you required to meet? I am currently working with an 'S'-type load cell. The twist in my case is prevented by the system design and the amount of deflection has no effect on the data. Maybe there is something that can be done in your case that would allow you to remove all that added hardware around the loadcell. Do you have any pictures or can you post some details about what your trying to do at a higher level?

A couple of screen shots showing the CAD overlay with a Smith and the other using the VNA for some phase noise measurements.

Feri, I tried to attach some screen shots for you, but the site seems to hang when I do this. I have done what your wanting to do with a couple of old HP VNAs. The problems with mine are that there was no real good way to display the data direct. I ended up doing some graphic overlays with a transparent background and placed them over an X-Y graph. This way I could display polar, Smith, etc. on the same graph. This worked very well for a generic type program. The one VNA I have has a built-in SOLT calibration, the other does not. So I just wrote this in Labview. In some cases I just wrote programs for a specific test. Easier than trying to make a generic program that would do everything. Do you have the programming manuals? If so, this shouldn't be too hard to get working. More time consuming than anything. If you run into a specific question and have the manuals, maybe I can help.
