  1. I think that maybe a tool to analyze dependency links would be helpful. Not just for this type of issue either. In a couple of our projects I end up saying "why is that class being pulled in"? Many times you end up with a "uses a" relationship with another class (static vi reference, passing a class into another class's method). If you could visually and programatically inspect your class relationship it would be great. I am wondering what Symbio tools would do with the weird setup I had going (we don't use them). A tool like that would be pretty nice for code reviews. Just a simple re
  2. Slight restructure worked. I had some weird linkage because of some static vi references. Database class was clean. So my main GUI class is passed to all main screen guis as data from screens is sometimes shared (they are plugin screens for a sub panel). I could of done it diff but that is what I ended up with. Anyway, the GUI screen vis were part of the main GUI class because they use the main GUI class. For each screen I have another class containing the control refs for that GUI. In the init function for the screen class I had a static ref for that screens gui (which was part of the main
  3. Posting here because NI forums is down...plus I found this thread which may have something to do with my problem. So what if there is a class that both the XControl calls and the Main class calls? For example, my Xcontrol calls a database class (which calls .net ADO), but that class is also in the dependencies of my main GUI class (which the XControl is also dependency of). I've been dealing with crashes, bad property and method nodes for the last two days am pretty much at that point where I start posting on forums. So my GUI class is in charge of getting data from and updatin
  4. I have stopped using this tool because the latest version of tortoiseHG will now go through all the files first and then give a list of conflicts. It also allows you to select local or theirs and can use a merge tool of your choice on individual files (in the case of VI's just use lvmerge directly).
  5. Since the XControl is only being used in my application and in one spot I was able to fudge a little and use the following code. Note the plus 10 which I think is due to splitters or panes not being at origin. I think NI also has a similar issue with their tip strips that has been documented. If you hover over control that is in a paned window that is in a subpanel you will see it. The location of the tip strip can vary and to get it in the correct place you have to scroll the pane. Maybe this is fixed in 2012, but haven't switched from 2011SP1 yet so I'm unsure. Anyway here is the code
  6. I am writing an X control that launches a popup that I want to place in reference to a control that is part of the XControl. It worked ok when the X Control was in a normal VI (even with multiple panes), but when that vi is in subpanel it always shows up in the same location. It gets the same "panel coordinates" everytime regardless of where the top level vi is placed, but changes when the subpanel is moved on the front panel of the main vi. It seems like I need to go one more level up, but so far have been unable to find a way to do that. It is almost like instead of "owning vi" I need the
  7. I did a quick search of the website but I didn’t see something like this posted so I’d thought I’d post it. It’s probably been done before but I found that it pretty helpful in my current project. I usually use DVRs whenever I want to use the aggregation pattern (zero or more relationship). Many times though I want to sort or return an object from the array based on an attribute in the object (like name). Since I am using a DVR I found I can quickly make a hash table using variant attributes. I just use the “Name” or other unique value and make the DVR the value. I can then lookup a DVR
  8. Question posted on NI's site. Thought I would list it here in case you don't check NI's forums and you have an answer for my question! http://forums.ni.com/t5/LabVIEW/Setting-quot-Scale-Objects-While-Resizing-quot-programmatically/td-p/1970005 I am thinking of sharing this API after I get this figured out because it makes collapsing / expanding panes a breeze. Is there is a different \ easier way to accomplish this? I have attached what I have so far in an example vi. MessingAroundWithSplitters.zip
  9. I mis-wired the unbundle, but that occurs after VData to Cluster function.
  10. I ran into an interesting issue with the Array of VData to VCluster when using XControl references as part of the VData. It looks like it puts it together correctly into a cluster, but when trying to type back to the XControl reference type it throws an error. You can convert it back to a normal control type, but when doing generic sets on controls in a cluster that method doesn't work very well. LV2011, Latest verison of the library. Screen shots here and code attached. I actually tried it with a couple different XControls and it didn't work. I wouldn't think that this behaviour is n
  11. Great API. Couple comments and suggestions. I was using a couple of panes in my application and so the locations got a little messed up. I modified it so it could register pane mouse down events instead of vi mouse down and it works pretty good. Although I don't have a current need I noticed that you can't register multiple controls on the same window or in two windows that are up at the same time. Finally it seems to take a little bit of time to load because it is using vi server. I am using it on some popup windows and when I switch between step interfaces quickly it is a bit noticable
  12. I was going to post on the NI site, but they have one huge LabVIEW forum so I though it might get lost. Was not aware that every post was read there. Thanks for the information and for entering the CAR.
  13. I am flattening an array of classes and loading into an MSSQL database in an XML column. When the XML is returned it is formatted to take up less space. Which means a line of "<Cluster></Cluster>" becomes "<Cluster/>". When returned in this manner I get an error: 1403 LabVIEW: Attempted to read flattened data of a LabVIEW class. The data is corrupt. LabVIEW could not interpret the data as any valid flattened LabVIEW class. Lines that have <Val/> and <Name/> work ok. It is only the custer tag that has the issue. I have attached two xml files...one with <
  14. Finally got around to checking it without recompile and it works as expected for me. Private function has an X and the public functions do not.
  15. I did not try that yet. I did however realize that the red X on the property node vi was because I had made it a private function. I will try it without compiling, but will probably do it tonight.
