Path problem for "Load VRML File.vi" in EXE

Hello,
The new integrated 3d Picture Control functionality in LabVIEW 8.20 is amazing. It is a really easy to use implementation of OpenGL. I've discovered one bug/issue when building VI's to an exe that includes the 3d Picture Control:
If "Load VRML File.vi" is used, in the executable, you will encounter a LabVIEW Error 7 due to a path problem in the following vi:
NI_3D Picture Control.lvlib:Load VRML File.vi->NI_3D Picture Control.lvlib:NI_Old 3D Toolkit.lvlib:Read WRL file.vi->NI_3D Picture Control.lvlib:NI_Old 3D Toolkit.lvlib:Initialize.vi
The File Not Found problem will prevent the vrml file from loading. Navigating down into the subVI's of the "Load VRML File.vi" shown above easily reveals the problem. I've included a screenshot of the diagram of that VI. The relative
path resulting from the double "Strip Path" operation is not valid
in the executable. I'm not sure where that "definitions" file resides
in the runtime deployment or if it's even included, so fixing the path to account for the differences in the exe vs. development environment path is not an option. I'm also usually very hesitant to make any mods to anything in vi.lib.
For the development environment, the "definitions" file can be found at: [LabVIEW 8.2 dir]\vi.lib\picture\3D Picture Control
The easy fix is to include the "definitions" file in the same directory as your exe when you build. Fortuitously, this does the trick because the first strip path gives the path to the exe and then the second strip path results in the path to the directory where the exe resides.
Hopefully NI will fix this path reference properly in future revisions.
Enjoy!

Question for load VRML file with scale and position missed

Hi,
I trid to read a .wrl file from the "load VRML" vi, most simple .wrl models can be correctly read but for some more compliacted models their scales and positions were incorrect.
I attached the file which I read the .wrl file and a car model from Matlab Virtual Reality toolbox. The file can be read but their position and scale was missed. I check this model on other VRML readers and I believe the car model is correct. Does anyone know how to fix this problem?
Thanks,
-Alex

Hi Yi Y,
Thanks for your reply.
The attached files are the correct .wrl file and the one read from LabVIEW.
The colored is incorrect, the car is seperated to some parts, and the scale of some of the parts are wrong.
I think you can use any .wrl reader to read the wrl file I posted, all the reader I tried can read it successfully besides LabVIEW.
In the vi I have you can try to adjust the scale or rotate it then I think you can find the seperated car parts.
I will appreciate if you can give me any suggestion. Thanks,
-Alex

Loading Vrml files in Swing using java3d loader

I've got problems loading Vrml files in Swing using java3d vrmlLoader. It seems to be only able to load vrml files that contains simple geometry like squares, cones etc. But when it comes to complicated shapes like IndexedFaceSet, its a blank. Does anyone know why?
What are the points to note when loading vrml files? Doesn't the code:
vrmlLoader = new VRML97Loader(VRML97Loader.LOAD_ALL);
and
scene = vrmlLoader.load(loadUrl);
load the entire vrml file? Is there any comprehensive tutorial or example that I can refer to? The fly through in Java 3d demo is too complicated. I'm still pretty new to this field. Thanks.

Did you download the example VRML file I had listed?
First make sure you test it with that one...it that works
then maybe the VRML file you are using is not version
#VRML V2.0 utf8
...Actually, I think you'd get some parsing error if you
used a VRML v1.0, so that probably is not the issue.
Do you have the vrml97.jar file in you path, maybe?
Check you path in Windows by typing "path" in command window. If you have the vrml97.jar file then
that's cool...if not then you must add it to your path.
OR you can temporarily compile by invoking
the -classpath <path> command....I think you'll have to
do the same when running the code....so do:
javac -classpath PUTPATHHERE TestVrml.java
java -classpath PUTPATHHERE TestVrml
If that doesn't work, do you have Java 3D installed?
just checking...
I'm kind of lost as to what to do beyond that....by the way, I double checked my files and and recompiled and
reran them and they work fine. I've also checked them
on a different computer at work and they work their too.
So, long story short, it's something wrong on your end either with the java install or the vrml97.jar file not being in the path...I don't know much more.
Let me know if anything worked.

Issue in calling webdynpro for loading flat file in IP

Hello,
We have implemented the How-To load flat files in IP paper and we are facing an issue in that. The generated webdynpro runs on ABAP Application server but we need to call this from a Web template which runs on portal server.
These two servers are different and we don't want to hardcode the url in webtemplate as the server names will change in Q & P for webdynpro. Can anyone advise how we can read the ABAP Application server details in WAD may be using javascript and then generate the URL for webdynpro dynamically.
Regards,
Deepti

Hi Deepti,
We have also facing the same challenge. Could you please post the solution in which URL path change dynamically.
I have created the ABAP function module based on the below link.
http://wiki.sdn.sap.com/wiki/display/Snippets/BICustomWebItemtoLaunchanABAPWeb+Dynpro
But not sure how to call the function module using custom web item & java script. Coould you please explain the steps on the same ?

Problem in loading SWF file

Hi All,
I am facing a problem in file loading. I have a file
https://shopping.easycite.com/admin/tree/main.swf and in that file
loading another file named “editNodeFome.swf”. To load
"editNodeFome.swf" i am using related path. But the file is not
loading.
mcLoader.loadClip("editNodeFome.swf", _root.tempForm_mc);
Can any one help me to find out the solution?

show your mcl code or use trace(mcLoader) to confirm it
exists along with _root.tempForm_mc. and make sure editNodeFome.swf
is in the same directory as the html file that embeds
main.swf.

Other problems with loading Captivate files into Flash AS3 project

I have a Captivate file done with Captivate 3, published to
Flash player 9 that is being loaded into Flash AS3. The captivate
is a simple recording of some mouse clicks in a browser. I am
displaying the playbar along the bottom, and its buttons all work
fine except for the progress bar, where you can drag the knob and
scrub back & forth in your presentation.
This progress bar is not working as it should. I see the
mouse cursor change to a hand, but when I click I cannot drag the
knob to control the progress bar. The other buttons in the playbar
do work (replay, pause, play, back, forward).
This is a unique problem in that it is only happening when
viewed in IE (7) when loaded into my Flash AS3 project. When viewed
in Firefox in my project, or as a standalone SWF, or as a SWF
simply embedded onto a plain HTML page, it works just fine.
Does anybody have any insight?
Another thing I notice with loading Captivate files with AS3
is the the amount of output messages it displays. Rather annoying
(unless this is a "feature" I've yet to be aware of - heh)

Hi,
I know exactly how you feel, there is simple answer; replace
Captivate for Camtasia Studio 5 at techsmith.com. The weight on
those shoulders will be gone! You'll smile more, be more
socialable. One Happy Person.
I am very happy person ;)

please help me how can i load full xml into single column using command line without hardcoding in control file
Edited by: 907010 on Jan 10, 2012 2:24 AM

but strangely it's trying to load each line of xml file into table instead of whole fileNothing strange, the data parameter specifies the file containing the data to load.
If you use the XML filename here, the control file will try to interpret each line of the XML as being separate file paths.
The traditional approach to this is to have the filename stored in another file, say filelist.txt and use, for example :
echo "/u01/APPL/apps/apps_st/appl/xxtop/12.0.0/bin/file.xml" > filelist.txt
sqlldr $1@$TWO_TASK control=$XXTOP/bin/LOAD_XML.ctl data=filelist.txt direct=true;

Applescript: Problem Using Load Script File. Please Help :-!

My setup: file 1 is a script object and file 2 is the script that uses the script object in file 1. This seems straightforward, but I'm getting runtime errors when tryig to use the script object, whether looking at its properties or calling its handlers. The whole thing just doesn't work. What am I doing wrong?
Question 1: Is the 'load script' statement correct in file 2? It took forever and looking at many examples to not get an error in that statement. I don't understand why the path string is 'as alias'.
Question 2: When loading a script and specifying its path, is there a way to start with the current path (of the executing script file). All the scripts are stored together, but so far, I've only seen commands for absolute paths or user or desktop, etc. how can I get the path of the currently running script?
Question 3: Is the cURL syntax ok? I can't even get the script to run to that line, so I don't know if it will even execute.
Thanks a million, in advance.
Cheers,
Mark
File 1: this is the script library file
script AR_Redeye
-- IR Command URLs
          property outside_lights_ON : "http://..."
          property outside_lights_OFF : "http://..."
          on do_command(command_url)
          -- execute the url using cURL
                    set command_status to (do shell script "/usr/bin/curl -s -S " & command_url) as string
          -- the url (when opened in a web browser) displays 'success' or 'fail'
                    return command_status
          end do_command
end script
File 2: The script that calls the handlers in the library file
set arRedeye to load script (("Macintosh HD:Users:...:AR Redeye Class.scptd") as alias)
tell arRedeye to do_command("http://...")

If I may indulge you again, I've cleaned up the scripts according to your advice and made progress, but I am still receiving the following errors:
Applescript Error:
«script» doesn’t understand the do_command message. (see below for where it occurs)
I also get an error for referencing a property of the script object.
Might you provide some insight as to why this is occurring?
Still a little confused.
Thanks,
Mark

Sax Parser for loading XML file

We have a requirment by which we need to load huge XMl file in our DB everyday.
THe XML file format is like --

Complete code for loading swf file in actionscript 3

i have a swf
file which i want to load into a fla file and export as a new swf file. I understand this part but my actionscript 3.0 code that i put on frame one of the timeline does not work. I have tried every version i have seen online including in adobe's actionscript 3 classroom in a book.... and other books..... i want the swf to run immediately so i dont think i need any event listeners since i am not clicking a button or anything like that... just running the swf at start. any help wuld be appreciated... sent two day on this already... i can do it in actionscript 2 but have not figured it our in actionscript 3......... why does eeryone seem to do this slightly different too? a complete code would be nice since obvously i am stupid........
thanks

Show the code you put in frame 1. I don't think you can do what you say you intend to though. As far as I know you cannot create a new filein the way you explained you intend to. If you load the file dynamically as a separate swf, then you will always need to.
