Hi all, sorry i had to do some other work. @ O_o: We already took a look into the UML editor from GOOP: The code is horrible. @drjdpowell: Thank you for your Picture and your inspiration. Up to now we try an other way. We will report if we found a solution. Thanks again Oliver

Hi drjdpowell, thank you very much. How did you select the place for the function block (fb) you want to insert: - with a click on the wire or - bevor the selected fb Did you have a simple Demo of the surface, wich you can send us? We planed to program it with classes so we can send each object the mouse event with the coordinates. One of them will be get active then. Oliver

Hi all, instead of an script based flow control programming UI for our user, where they type text to control the measurment instrument. We want to program an graphical UI where they can add new commands per drag'n'drop from a Picture Ring to a surface. Similar to a flow chart tool (e.g.: yED Graph Editor), or to the UML Modeller from Symbio (Picture). But we are not sure how to solve this... Draw it on an big picture control: Then we have more work find the right object if the user double click it to configure it. We have more work drawing the flow arrows especially if the user move something. Draw it via scripting on a frontpanel and reload it in a subpanel: Then it is easier to interact with the user because we can use an event structure and using pictured boolean controls for the objects. But the arrows are still a problem. And perhaps the dead time is to long if the user works faster. Draw it to a small picture control in an array, because we just need rows and no colums? So our question is: How could we program this UI: Picture control, Subpanel or something else? Did anyone solve this by himself before? Thanks for help and sorry for my broken english. Hope i make it clear. Oliver

Hi Neville D, You are absolutly right. The invoke node "FP.Open" don't work in the same way on a RT-system like on a standard PC. Also if looked already in the help for that method. But NI just write "Available in Real-Time Operating System=Yes". That means in this case: you won't get an error running that method... That is no option for me because the RT-system running standalone. The task was to check the state wih a browser on any PC or laptop wich will be connected to the system temporarily. So i think i've to draw a graph by hand if no one other have an idea... Thanks Oliver

Hi all, i've a project on a cRIO with some I/Os running under LabVIEW 2012. Now i want to visible my results on a website with the cRIO webserver. So i wrote a web service witch show the content of some shared variables. Because the default website show only a table with each name and content of the variables, i toke a string variable and save a html link to a picture in it (<img src="myGraph.bmp">). In my LabVIEW code i get the image of the graph using a property node and save it to an *.bmp file. Code of the initalisation of the variable and saving an empty graph at start up: Now when i deployed my program the picture was saved and the website look like i want to. But when i run my cRIO as a standalone it seemd that he didn't open the frontpanel and so he take an empty picture with. I checked if the frontpanel was removed by the build specifications and i try to set a invoke node to open the frontpanel first. But both didn' help. I'm a native html but a good LabVIEW programmer. So i try to solve it in LabVIEW. But perhaps there is an easier way in html. But up to now i don't know how to reference to the webservice variables from an html file. I found an example for forms connecting to webservices. There i've to send the returned website with a LabVIEW build html string and i don't know how drawing an graph in html. Now i'm thinking about drawing my own graph in a picture with LabVIEW and saving them... So have anyone an idea how i get a graph easier to the website? thanks for help and sorry for my bad english grammar Oliver

Hi all, on an instrument they want to save the data in HDF5 format. So I tried to install the HDF5 library on my Ubuntu 10.10 (32bit) system with LabVIEW 8.5. I installed the hdf5-tools package over the packet manager from Ubuntu. After that i unpack the library to the LabVIEW system directory. Starting LV I found the HDF5-VI's in the function palette. But when i placed them he asked me for the libhdf5.so library. I found it under: /usr/lib/libhdf5.so.6 Now he asked me for the libh5helper.so library. I found it under: /usr/local/natinst/LabVIEW-8.5/vi.lib/addons/_hdf5/libh5helper.so But it seemed that the libh5helper.so file are corrupt or must be recompile. The error message is: library not found or failed to load So i load the source code from libh5helper.so and try to compile it but I didn't have success. (./configure -> make -> sudo make install) So my question is: - Did anyone else have the same problems and how did he solve it? - How can I compile the source code of the libh5helper.so? Thanks Oliver

Thanks David Boyd, very usefull nice tool. :thumbup: I can't count how often i missed them... Could you compile it in LV6.1? Beause a lot of projects are still running in 6.1? Thanks Oliver
