QUOTE (Eugen Graf @ Aug 2 2008, 04:12 AM) We do so, our reusable library consists both of single VIs and classes and we place them all in the user.lib, we also have that folder under version control. //Mikael

Hi I just came back from New Zealand where I held the OO course in Auckland at a company. During the first day of the course I go through the principle of OO-Design and Analysis and objects by flow and references. The second day we create a whole test system application from a problem description, using UML class diagram and then we implement it. I like to customize the course as much as possible depending on the student needs, so I normally like to know what kind of systems the students are developing. Cheers, Mikael

I'm using AutoIT-scripts compiled into exe-files that I run from LabVIEW. http://www.autoitscript.com/ //Mikael

Hi I've made a quick UML diagram of how I would have solved the design. When I get more time I'll try to give you more feed back. Remember that all base class methods should makes sense to the child classes. Cheers, Mikael

Hi Gustavo I've created dot net code that I call from LabVIEW without any problem, I also got the dot net code to invoke a VI when special event happens that the dot net code is controlling. I don't really understand what you are trying to achieve. But just to be sure, have you opened/called a constructor of the dot net class before you used it? You can create several constructors for a dot net class, the constructor in the example below takes 3 arguments. Cheers, Mikael

Hi This is the design your leaning towards: I would probably use a composite aggregation, which means I would have to solve the creation of the correct I2C object internally in the battery create methods. Using this way it makes it easier to use the battery class, as you don't have to worry about the communication interface. Of cause it will be harder to develop the battery class but you top VI will be simpler. For the I2C communication I would probably not do an active object design to start with, I might use a static attribute in the I2C-Implementation classes which I use to synchronise the read and write to the batteries so I don't run into any race conditions. Good luck

Remove this line: <Property Name="NI.LVClass.ParentClassLinkInfo" Type="Bin">....................</Property> and the reopen the project. I always use the GDS function "GOOP->Modify this class inheritance", to do this, but in your senario it can't solve your problem. //Mikael

You can use the Connectivity->Input Device Control-VIs for this. E.g. Download File:post-941-1213217744.vi Cheers, Mikael

QUOTE (Aristos Queue @ Jun 5 2008, 06:40 AM) When I read this I started to think about the "Paper Clip" Whould it be nice if NI added it in LabVIEW http://lavag.org/old_files/monthly_06_2008/post-941-1212705172.png' target="_blank"> Cheers, Mikael

QUOTE (Jim Kring @ May 28 2008, 04:42 AM) Hi I hope NI will abandon the LLB structure they are using in the exe-file or at least add folder support in the a LLB, this will make it possible to store everything inside the exe-file. One other painful thing I have is that a quite large application, with lot of classes and lvlibs, it takes me more then 30 minutes to build an executable and during that time I can't use my computer for something else, since LabVIEW uses all my resources. Cheers, Mikael

So you have to do this in your code then... Maybe it's because LabVIEW supports foreground and background colors for colors in development environment, and the Color Boxes gets 2 event one for the foreground and then one for the background color. //Mikael

QUOTE (Yen @ May 22 2008, 02:54 AM) I did a test right now. http://lavag.org/old_files/monthly_05_2008/post-941-1211425248.png' target="_blank"> ..and when sitting at the office and accessing my local network at home, it took 1448 ms per image. So on the same local network you should probably be able to get 2 images per second. You might need to use normal TCP/IP function so you don't need to reconnect every time, and use a normal HTTP Get command. //Mikael

Hi Jim I had these problems when adding drag support from the Project Tree to my UML modeller. I had to solve it by using the Input Device Control VIs. This code will do the first part: -Know when the move is over the Path Control. Download File:post-941-1211341397.vi -The next should be to check if the button was pressed, when you entered the VI (drag started outside VI) -Check for button released. -Then you'll get the Path-Value change event. But of cause you like to check the content of the dragged file before, the user releases. E.g. Flag that the file has the wrong format and can't be dropped here. I guess you have to use some windows API to get the content of the dragged file. Good luck, //Mikael

I use a web based camera and uses the Data Socket VIs to download the image from the cameras. Camera: Code: URL: --Mikael

FYI, I have the user.lib under version control, and then the .svn folder appears in the function palette. But by selection the Tortoise Option: Use "_svn" instead of ".svn" directories , I've solved that problem. //Mikael

QUOTE (Yen @ May 20 2008, 03:38 AM) The Endevo GOOP2, is pure LabVIEW without lvclasses, just like Sciware GOOP so that should work. //Mikael

Hi Tomi I've used LabVIEW to measure the composite video signal before. But what I never heard anybody managed to do is to generate a composite video signal from LabVIEW before :-) So if you get the fastest analog out card, and a real fast computer you could generate your own video signal and feed it to a TV :-) That would be something to show at NI-week! Good luck //Mikael

Hi Tomi I've experiensed the same kind of effect, when I run a convert application from EndevoGOOP2 to EndevoGOOP3, the project I tried to convert took 65 hours, and it spend a couple of minutes each, when saving a modified dynamic dispatch VI. I guess your Save All, is about to save that kind of VI... I would start by right click on the classes one by one and select "Save All(this class)", and you could also try to open one class (.lvclass) at a time. And then "Save All(this class)", this approach has help me a lot. You could also try to remove all inheritance links among your classes, save all, and restore the inheritance. Cheers, Mikael

I have had to use the "Deallocation VI", in one of my current test system. But I also needed to increase the memory to 3GB for LabVIEW to use. It's a simple switch in the "c:\boot.ini" file. [boot loader]timeout=30default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect [b][color="#ff0000"]/3GB[/color][/b] You can read more about this in the section "Enhancing Virtual Memory Usage" in the LabVIEW help Contents: "LabVIEW 8.5 Features and Changes" Cheers, Mikael

What I'm missing in LabVIEW is the ability you get in .net using Measurement Studio. Where you can override any calls to the Graph, e.g. When a plot point gets drawn you can check for some criteria and just change the color or shape of the point. --Mike
