  1. AQ I will try again today and see if i can replicate it.... Dan
  2. FragRz I didn't mean the private Method you referred to , I was talking about the when you have LV open and go to Tools -> Compare -> Compare VI Hierarchies... Dan
  3. Well , since I installed the evaluation version of LV2018 i played around with the Compare VI Hierarchies tool , it actually does everything I need ... But , be cautious using it at first when Creating a Report , it did the webpage report just fine , when I tried to create a Word Doc it failed , AND , deleted everything in the directory it was supposed to save the Word doc in , luckily I was using the Temp directory so it wasn't a big issue , in fact on a second try at it , it deleted the Temp directory too , not just the contents... As I said I am using the evaluation version , so , maybe something is wrong with my install. Dan
  4. FragRz I have the evaluation version of 2018 , so i looked into the 'User Interaction:Compare VIs XML and it does just what I need .... I will have to wait until we upgrade to utilize it ... Thanks Dan
  5. After much googling I think I know the answer , but , I will ask here... I need to write a utility to compare vi's in a large project , and probably future projects.. Automating the Compare Hierarchy is pretty simple , but , I need to go one step farther and and show the differences circled then saved as a jpeg etc.... As of now there doesn't appear to be a way to automate showing the differences , it will be a real pain to have to do it all manually ... We are currently using LV 2012 , but , will be upgrading to either 18/19 soon... Dan
  6. Well , your memory is working , I went back and disabled the part that replaces the DD control , and it works as expected , I think I will just rename it ... the 2 others on the front panel are of the Default class , (In/out) , it appears I have to replace them as I get the Connector pane doesn't match on the DD vi's if I don't .... it works , so now I will move on to the next issue on my list , I may come back and revisit it at a later date to see if I am doing something not quite correct... Dan
  7. Yep , basically all I did ... if I don't change the controls , it doesn't work correctly , I will investigate a little more and see if I can eliminate that step... Dan
  8. Ok , I decided to start over , turns out there is an invoke node LVClassLIbrary.Save a copy... this copies everything to a new directory , then I just need to replace the control(s) , set the parent and save the whole thing using Save All This Project.vi.... works perfect ... thanks for the pointers .... Dan
  9. Ok , I would like to programmatically copy a Default class and a Default Test.vi to another folder say , XYZ , rename the Default Test.vi to XYZ.vi, then change its DD terminal from the default class to the newly created XYZ.lvclass and add it to the project. I currently can do everything I need to do , except , after changing the XYZ parent to the Default class I copied it from , add it to the project etc.... When I try to open the newly created/renamed XYZ.vi from the project I get a dialog box that says , "Default.lvclass:XYZ.vi" is at the expected path but it is part of a library. Default.lvclass:XYZ.vi" will be opened but it will be removed from the project". I really need to be able to do this programmatically , we will have hundreds of test cases that will have different functionality but use the Default Test.vi as a starting template , I also have to assume that future users will be totally unaware of classes and how to create/use them... I have a framework that should be very expandable in the future , I just want to automate as much as possible.... <EDIT> I should mention this is in LV2012 <EDIT> TIA Dan
  10. Well , I closed LV down and restarted it and opened the project , now I can do a save as and preserve the inheritance , no clue why it didn't work yesterday , but , seems go to go now.... Dan
  11. I have a class that I would like to copy (up to 70 times) and keep its inheritance on each copy , I tried doing a save as but , that didn't work.... just trying to avoid re-creating this dozens of times , the main reason for doing it this way is to take advantage of DD , and that we can override a couple of the instances ... Dan
  12. Well as usual , after I post on a public forum , I figured it out , not sure if it is the best way , but , it works... I create the half sine arbitrary file , load it up to be "played" , set trigger to external , set burst count to 1 , then when I need the pulse I use a software force trigger command... Dan
  13. I am totally new to Arb's , I need to output a single pulse of a half sine wave .... how does one go about that ? TIA Dan
  14. Hooov I was kind of worried about that .... I have already started down the road of populating as the user clicks on the control... I wish there was a more elegant way of doing this , but , I can deal with it this way .... Or if a Multi Column list box would allow you to highlight different cells in columns I could work with that too... My limited messing with the multi column list box it didn't appear I can do that either... Thanks Dan
