Help with Primary/Subreport and Shared Variables

I've been trying in vain to get this to work.
Main Rpt:
In GH1 I've got shipping address information.
In GH2 I've got a linked subreport where I have shipping addendum information.
Goal...I want to get two fields from subreport to show up in shiping information showing in GH1 on main report.
Sub Rpt:
Addendum information is in GH1
Here is my formula field from the subreport GH1 section:
Whileprintingrecords;
Shared StringVar OpCoSD;
OpCoSD := {tmp_confirm_delivery_vw.operating_company_sd};
Main report:
Here is my formula from the Main rpt GH1 section:
Whileprintingrecords;
Shared StringVar OpCoSD;
OpCoSD;
Nothing shows up in the main report....data showing fine in Subreport.
I've read other posts that seem to say for this to work I have to duplicate my subreport and place it "above" the main report GH1, white it out and shrink it so it won't display, because it must process first before the main report GH1 section.
Many thanks.

Carl,
Yep...after reading more about it on various sources...that's what I tried and it work just as you described.
Thanks so much for your excellent support on this forum.

Problems with builded app and shared variables

I got connection error message (Invalid server: cannot connect to server) when selecting a shared variable using dashboard. The app is running on a Win7 PC.
I have no problem connecting the PC's IP at my dashboard indicator, even, I can select the shared vars library of my app.
I opened the ports on Windows and Router TCP: 2343, 59000-60000 UDP: 2343, 6000-6010, and created new inbound rules for the kads.exe, lktsrv.exe and tagsrv.exe programs and installed the Run-Time 2013 engine on that PC. By the way, the application also has HTML files created with the web publishing tools that is working OK.
When I test the application on my develop PC (with LabVIEW 2013) everything works fine.
Did I miss something?

Hello jesushidalgo,
Make sure that there is not a personal firewall enabled on either computer that could be blocking the NI-PSP packets.

Datasocket and Shared Variables

I am curious if there is any advantage to using Datasocket to read/write shared variables (as opposed to a direct read/write). I'm specifically talking networked shared variables here.
Is there any speed advantage to accessing shared variables thru the Datasocket functions? Since both a direct read/write and a Datasocket PSP read/write talk to the same variable engine I assume they are equally efficient but I'm looking for confirmation here. I've seen benchmarks for shared variable performance but none of them use DS/PSP to access the variables.
Normally I would not even think of using Datasocket to access shared var's but where I currently work we have a large app that does this and it works great. I suspect that this functionality only exists in LV8.x for backward compatibility and non-Windows OS compatibility and is not really meant to be used for new, Windows-based apps? Am I off base on this?
I am working in LV 8.5, BTW.....

Hello Jared,
Thank you for the reply with clarification.
Based on your comment, I changed the buffer parameters and also tried the programs with two different data types, previously StringArray and now String.
In the attached LV8.6 project, you have all the programs, and shared variable library to review my tests.
There are two sets of two files - each set has a Write Shared Variable and Read Shared Variable file. One set is for StringArray type Shared Variable (named StrArr in the library), and the other set is for String type Shared Variable (named Str in the library).
String Array example:
MultipleDS-Write-SharedV-StrArr.vi / MultipleDS-Read-SharedV-StrArr.vi
In my String Array shared variable, I use only 4 element array, each having 4 character strings - meaning 16 bytes per String Array data. I have two loops in the write file, writing to the same variable, an array of 4 strings, each loop continues until the loop index is >0. This means, sometimes, depending on the processor speed, the variable will be written 3 times or 4 times (the variable could have a new value before the loop condition is checked).
So this means, if I have buffer of 100 bytes (16*4=64<100), it's enough for 4 such arrays (of 4 elements, each element with 4 characters) could be buffered to have sufficient time at the client (Read) program to read them.
I am putting 2048 bytes in buffer, which is much more than sufficient in my case.
The writer loops run with 200 ms to wait for each iteration. The reader loop runs with 100 ms in DS timeout and 100 ms in wait timer. This gives results without any loss. However, if I run the reader loop with 1000 ms to wait for each iteration, the data is lost. The buffer is not maintained for 2048 bytes.
In the read program, just to make sure if all data is read or not, I am showing data in two different string indicators, showing data of each loop.
String example:
MultipleDS-Write-SharedV-Str.vi / MultipleDS-Read-SharedV-Str.vi
The String Array shared variable didn't show values in the Distributed System Manager. Hence, I created another simple variable with String datatype.
The writer program writes strings of 4 characters, one-by-one, in two loops. Meaning, total 8 strings of 4 characters each are written in the "Str" Shared variable.
The reader program, however, doesn't always display all the 8 strings. Although the wait timer is not high (slow) it still misses some data usually. Data is overwritten even before the buffer is filled (in buffer, I have defined 50 strings with 4 elements in each).
In both of the Read programs, I read using datasocket. I think thought datasocket has more ability to buffer. Earlier I had "BufferedRead" in DataSocket, which I have changed to just Read, because BufferedRead didn't give any special buffer advantage in the Shared Variable reading.
---- This is an update on the issue.
Ok, just while typing the last paragraph above, regarding datasocket, something clicked in my mind, and I changed the DataSocket functions to simple Shared variables (completely eliminating datasocket functions) in the read programs as well. And bingo, the buffer works as expected, even if I have reading loops very very slow, there is no data loss in any of the program sets.
The two changed Read programs are also included in the attached project - MultipleSV-Read-SharedV-Str.vi and MultipleSV-Read-SharedV-StrArr.vi
So this means, I can completely eliminate DataSockets (not even using PSP URLs in DataSocket Open/Read functions) from my programs.
One question here, what will be an advantage of this (or any side effects that I should be keeping in mind)?

Use buffering and psp with datasocket-VIs and without any binding and shared variable node

Hello,
I'm using LV 8.5.
I'm trying to develop a multiplatform (windows and mac os x) and multi-computer application. II want to get executables running on each device, communicating through the network. Communication process includes datas (such as images) and events messages (something like "Hello, I got an error" or "youyou, my work is done" or "I'm hereeeee!!!!...."). I do need a communication without any loss of data.
I worked a lot and wanted to test a psp-based design, without any binding nor shared variable node (mac os...) using data socket VIs and SVE buffering.
I managed to :
- deploy shared variable library dynamically (even in an executable)
- communicate between two PCs with datasocket VIs
However, I never managed to enjoy buffering (even locally with one VI doing the deployment and writing datas and another one for reading).
I worked hard (dynamic buffering setting, dynamic buffering watching like in http://zone.ni.com/reference/en-XX/help/371361D-01/lvconcepts/buffering_data/ and in the example "DS send image" and "DS receive image" in the labview examples, trying to use "?sync=true" in the URL, etc...) but no way to get things work.
I attached a jpeg of an example of receiver and sender. I use wait commands in both receiver and sender to test buffering
Receiver do receive datas (the last written) but buffering doesn't work.
Did somebody did that before ? (better than me...)
Thanks
Bo

Hello,
Indeed my problem has been solved. My error : in the While loop of the receiver VI, I always reactualize the PacketsMaxBuffer and OctetsMawBuffer parameters, what resets the buffer and make it appears ineffective.
I now set the PacketsMaxBuffer and OctetsMawBuffer values only once at the begining of the VI and the psp buffering works perfectly.
Sorry for the desagreement...

Strange behaviour with Vision 8.2 and Shared Variable 1D Image Array

I've just upgraded to LabVIEW 8.2 and Vision 8.2. When loading a particular VI, it is searching numerous times for ...\LabVIEW 8.2\resource\objmgr\IMAQ Image.ctl - which of course doesn't exist. As best as I can track it down, this seems to be cause by a Shared Variable I have in the project which is a custom control of a 1D array of Image.
So I've created a new project from scratch to illustrate (attached). The VI runs OK, but any editing means that this non-existant control is searched for again. Of interest is also that there is a coercion dot where the Image is used, but the data type on the wire seems OK. Creating a control (rather than a Shared Variable) works fine.
Anyone know what's going on here?

Hello Greg,
I downloaded your project and opened it up on my
system. I received the same results as you
did – I tried to open the project it searched for \LabVIEW 8.2\resource\objmgr\IMAQ Image.ctl. I also used the 1d Image.ctl file as a constant on my block diagram and it did not
show the coercion dot as you mentioned.
There does seem to be some strange behavior going on here
with the coercion dot and the shared variable.
I will have to look further into it and report this to R&D.
But for now, we need to address your application. What is the goal of your application? How does using a shared variable with IMAQ
Images help you get there? You may be
aware of this already, but when an Image wire is passed around LabVIEW, it is
not actually passing a copy of the data in a dataflow manner. The large size of IMAQ Images necessitates
that LabVIEW pass around a pointer to the IMAQ Image. Therefore, when an array of Image controls is
made and used as a shared variable, the controls do not contain the actual
image data. Instead, they contain
pointers to the IMAQ Images. When they
are passed into a shared variable, unexpected results may occur. If the shared variable is network published,
for example, another computer on the network would receive a pointer to an
image that it would not be able to find or access.
There may be a much better way than shared variables to
achieve the same functionality you are currently looking for. If you do in fact require shared variables,
you could use IMAQ ImageToArray.vi
to create an array that can be used in the shared variable like any other data
type, and then use IMAQ ArrayToImage.vi
on the other end to be able to view the array as an image.
Please post back with more information about your
application and we should be able to find the best solution for you.

Modbus and shared variable performance in large application

Hi all,
I am preparing to work on an application which is going to reading from up to 500 Modbus input registers on a CompactRIO over Modbus Ethernet using the LVRT Modbus IO Server implementation. I've put together some minor test VIs on the local network to test the Modbus connectivity and understand in the shared variable minding mechanism.
To save potential headaches in the future, do you all have any best programming/proejct management practices for using high channel count Modbus applications? Has anyone done high channel count testing (similar to the link below) but for shared variables bound to a Modbus I/O Server? Any caveats I should keep in mind?

If your application can deal with it I would recommend staying clear of the 'Networked Published' option.
When I started my Modbus development on cRIO....I left it enabled, and with ~100 shared variables on a 9074, the CPU was railing, and I saw a buffering behavior on the shared variables (which was not desirable in my application).
In my application I am using the old modbus library (as apposed to the new API) for cRIO to slave comms, the cRIO being the master.
I am also using the IOserver making the cRIO a slave to an external SCADA - and it passes essentially the same data arrays as I use on the modbus library for my local HMI [Not an NI product].....Which is two full Modbus frame writes (@ 120 words each, and about 60 words more for ~300 words outbound from the cRIO).
The IOserver slave was a recent addition and did not add much to the CPU load - although only 16 bytes is high speed, the balance of the total word package is at either 1 second or 3 seconds.
So, in my experince, the 'Networked Published' option adds significant CPU loading (on entery level cRIOs) YMMV.
I am huge fan of the shared variable engine (some at NI were pusing the CVT, and TCE etc...). However most of my shared variables are not the Networked Published variety (excepting local module channels) those have remained networked published for DSM (Distributed System Manager) use.

Mapping in OWB with primary key and foreign key relationship

Hi all,
I am new to this datawarehousing field. I have just started my career. I have to now create a mapping in owb where a table has a field which is a primary key of another table in the same staging area. If you guys could help me out with the a method it can be created that would be very helpful to me.
I thought of 2 ideas,
1. If I can use a look up, but then I am not sure if i can use a lookup for primary key, foreign key relationship. If I can use also, I do not know how to use that.
2. What if I can directly take that the first table and link the primary key of that table to the second table which uses that primary key of the first table as one of its fields.
I do not know how feasible these methods are. Please guys help me out.
Thanks in advance.

I have a similar case where table a and table b having relation but table a got inserted with data and table b is empty so there no values for foriegn key column in table b to realte with table a.
Now i want to load table b foriegn key with primary key column values of table a.
how can we do this in owb
thanks

Help with managing RAW and jpeg images and installing iphoto 9

Greetings: Fist, let me make the neophyte apology and plea - I'm sorry, I should have come here first; I didn't and now I need your help.
I have just purchased a macbook pro (still in its box) with updated software for my older imac os x. I have a number of Canon related photo editing programs (that came with my 40D digital SLR) and Adobe photo elements 6 for mac on the imac. Following some erroneous advice I have made a complete mess of the pictures folder's content by trying to delete images directly from that folder (there are now 6000+ images in the folder, many of which are duplicates(?). Most of the images are not tagged or labeled and some have been organized in/by iphoto (I corrupted the iphoto's library structure very early on by disrupting and editing its images - which might explain why iphoto had a difficult time 'finding' and displaying some of my photos). The picture folder now holds jpegs, smallRAW images (a Canon 40D photo format) and various duplicates of the orignal images - (some of the duplicates don't display as images, but as jpeg logos, which, when opened contain duplicate image or are completely black) The first time I downloaded RAW images into iphoto 6 the RAW data displayed as a black image. When shooting in smallRAW on the Canon 40D, the camera produces a jpeg image for 'easy viewing and editing in the camera' but it looks as though iphoto 6 made duplicates of the jpeg and the RAW data and stored them in different locals in the picture file. In an attempt to get the number of images down, I have been trying to delete them from the picture folder. (My daughters both download images rather indiscriminately in hopes of 'editing them on the computer' which inevitably does not happen) and there is a lot of experimental bracketing of images - shooting raw and different Camera formats etc., all of which need to be cleaned up before I proceed.
Sometime in the not-too-distant future I would like to have iphoto 9 running on my imac with a clean library of images and a seamless way of downloading, editing and storing images (including the RAW data).
The macbook pro is for my highschool-aged daughter, who will run iphoto 9 but not have any RAW image data on her system. She would like to copy some of the old iMac's images to put into her own iPhoto 9 library (probably using a disk, email or on-line photo service - ideally, I would like to be able to copy and remove a number of those images from my HD and give them to her for the macbook)
A few questions and queries: Can I 'dis-able' iphoto 6, while I delete images (RAW and jpeg) from the picture file? (and is this even a good idea).
Once I have edited the # of images down to a reasonable size, should I re-launch iphoto 6, rebuild the iphoto library and then update to iphoto 9 or skip v6 and rebuild with v9?
And now for the 'how stupid is this guy question' - I really had planned to purchase an external backup; but between new the macbook, car repairs and braces it has never come to fruition. So, I have never properly backed up my images. What is the bare-bones, least expensive method for me to do this? I'd even consider burning everything to disks if that works. I can't afford the $ to purchase a new external hard drive right now (really). Budget is set aside mid-November for one though.
I've been looking through some other discussion boards and it looks like I'm not the only one having RAW image issues. I know that shooting smallRAW with the companion jpeg is probably not helping things but I take my camera equipment on extended canoe trips - and we like the ease of on-the-spot editing with this format.
Thanks in advance for your help - Mark

Terence, Is the picture folder the primary source for the images or does that data reside somewhere else?
If you gathered them there, then yes.
I really don't want to have to go through 14,000 images looking for the pictures that I want to keep (or is that my only option?).
Only you can decide what you want to keep.
Why does the computer keep making copies of the images and filing them under date and events?
That's how iPhoto works. It's not a problem usually, only you did go in there and make a problem, and now we are trying to fix it.
You advise not to muck around in the picture file via preview,
No I don't. I advise not to much around in the iPhoto Library Folder.
but if I download images through a program other than iPhotos - image capture or adobe aren't I doing that anyway?
Adobe what? Adobe is a software manufacturer who make many excellent applications, you need to be more precise. And no, if you import photos with Image Capture or “adobe” no you are not interfering with the iPhoto Library Folder.
Can you edit a base image file somewhere and remove it from the HD without iphoto making a copy of it and storing it somewhere else?
This is stunningly easy. Don't use iPhoto. Use an image editor.
I want to look the negatives, decide which ones I want and throw the rest away. Can that be done or am I way off course?
Yes, and iPhoto (or similar apps) make this really easy.
Hook up your camera. Import the pics to iPhoto. Go through the imported pics. Trash the ones you don't want. Then process the ones you do. But you must learn how to use iPhoto to do this successfully
To trash: put the pic in the iPhoto trash and empty it. This removes the file from iPhoto and the Hard Disk.
Process it: If you want to use another editor: You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.

Compact FieldPoint and Shared Variables

Hi Real-Time community,
let me first to describe my problem: I have a project running perfectly on Windows XP machine. The Real-Time Target (compact FieldPoint) is acquiring a data from different sensors and sends them via Shared Variables to the host machine (WinXP). Now this host application has to migrate to Windows 7 machine, which second Ethernet port is also connected to the compact FieldPoint's network. I have created an installer, it run on Win 7 computer but I I see no data there. Shared Variables are standart network-published. What else I need to configure to get Shared Variables visible over there? Thank you in advance for any helpful hint.

Hi,
we do have the full edition of Signal Express, this is not the problem. We are already logging the information comming from our cFP-1808 : TC-120 and AI-111 module. The problem is that the AI-111 module is a 4 to 20mA module, and we have thermocouple connect to it. We want to read temperature in Signal Express instead of mA.
There's a option in MAX where you can add scaling to a cFP module. This scaling work in MAX, in the OPC server of the cFP, but not in Signal Express. In Signal Express, you still read the mA value.
I know we can add a formula in Signal Express, but we don't want to do that, when there is an other option in MAX.
Thanks

Need help with iphoto 8 and two users on same computer

Let's me start by stating I'm brand new to Mac. My wife is putting all our photo's under her user name, but when I open my iphoto program I don't see the same photos. I thought I set up my iphoto to share from hers but I've obviously done something wrong. Any help would be appreciated. Thanks in advance.

Afrergy
Welcome to the Apple Discussions.
There are two ways to share, depending on what you mean by 'share'.
If you want to be able to see the pics, but not add to, change or alter the library, then enable Sharing in your wife's iPhoto (Preferences -> Sharing), leave iPhoto running and use Fast User Switching to open your account. In your account, enable 'Look For Shared Libraries'. Her Library will appear in her source pane.
Remember iPhoto must be running in both accounts for this to work.
IF you want to have the same access to the library: to be able to add, edit, organise, keyword etc. then:
Quit iPhoto in both accounts
Move the iPhoto Library Folder to the Users/Shared (or an external HD)
Make sure the file permissions are set to allow read/write access to everyone
In each account in turn: Hold down the option (or alt) key and launch iPhoto. From the resulting dialogue, select 'Choose Library' and navigate to the new library location. From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
However, there is a catch with this system and it is a significant one. iPhoto is not a multi-user app., it does not have the code to negotiate two users simultaneously writing to the database, and trying will cause db corruption. So only one user at a time, and back up, back up back up.

Hello friend..
The error you are getting *"ORA-27101: shared memory realm does not exist"* may be coz you are trying to connect to your database which is already shutdown not as sysdba user but as some other user, becoz of which you are getting this error. It sometimes happen that the service of the database is already started but when you try to connect to a shutdown database as users other then sys even having the DBA priviledges you cannot connect to database.
Try to connect as SYS user hope your problem will be resolved.

Windows XP vs Windows 7 and shared variables

I have a stand-alone app I install onto 2 different PCs. One PC runs Win XP and the other Win 7. The application must deploy 3 shared variable libraries before the executable can run. On the Win XP PC, I can be a user and accomplish this. On the Win 7 PCI must be sys admin. If I login as a user in the Win 7 PC, I must have the app set to run as sys admin otherwise the user cannot run the app. What has changed?

Faustina,
I do not know of a good way around this. However I did find several links that I think should help. First here is information about what is going on http://digital.ni.com/public.nsf/allkb/E06C1800F5AFCCBF86257236006C9F2A?OpenDocument. Next as a workaround I would suggest setting the exe to run as admin you can find instructions for that here https://technet.microsoft.com/en-us/magazine/ff431742.aspx.
