Long string problem while communicating with DLL

Hi
In our project, we encountered problems about passing strings longer than 255 characters while the SAP system communicates with a dll method.
We do not want to use file operations as the intermediary layer. Is there a way to handle this situation other than a file-related solution?
Thanks & Regards...

Hi
Sorry for answering late. The dll is created via VB. At the ABAP side, a type having length greater than 255 or the string type gives error. This seems to be a restriction of OLE interface?
Thanks...

Parts of string lost while communicating with Arduino.

While communicating with arduino, the string I receive from arduino is buffered but it isn't totally read by LabVIEW
and some information is lost, changing the data I plot. Anyone knows how to solve this problem?
Maybe useful information:
Arduino mega
Baud rate: 19200
Loop delay in Arduino: 10 ms
The string is composed by 3 integers values concatenated like this:
gh123ab123cd123ef
I´m attaching the Vi.
Thx very much!

Problem while communicating with ECU through NI USB CAN

Hello sir,
I want to communicate with ECU through NI USB CAN interface while i tried to communicate with ECU it gives timeout error. here i am using CCP version 1.0, ECU toolkit 2.1.4 and NI CAN 2.7.2 .if you have any problem that communicates with ECU using CCP version 1.0 Please attach it.
Thanks and Regards,
Madhan

So for the fifth time you start a new thread about the same problem!
If you don't get any response to your threads, it could be because you are not giving a lot information about your problem.You could start with giving the vi you have problem with, so that we can see what you are doing.
You also need to give any error code and a description on that you have done, in details!
You also had one response in one of the other threads, it is polite to make an answer when someone is replying to you.

Error while communicating with the server

Hi Experts,
I'm having the following issue, when I try to send data using an input schedule the server says that there was an error while communicating with the server and don't send the data, I took a look at the log file and it says the following,
==============[BPC Logging]==============
[Message Type] : ERROR
[Job Name]     : OSoft.Services.Application.FileAccessService.FileAccessServiceProxy
[DateTime]     : 4/6/2011 8:42:44 AM
[UserId]       : CAMESAP\BPC_SYSADMIN
[Message]       : UJF_EXCEPTION E018     Cannot find document/directory 0
==============[BPC Logging End ]==============
Also i went to take a look at the default script logic, because i remember that this error happened to me when i wrongly program an script logic in the default.lgf but it shows me the following error when I open it,
System.InvalidCastExeption: Specified cast is not valid
at System.data.DataColumnCollection.get_Item(String name)
at System.data.DataRow.get_Item(String columnName)
at Osoft.Consumers.Admin.AdminLogicClient50.LogicMain.GetLogic()
If I compile the file, the error stop appearing, put with all new logic files it happens at first, I think that these two errors are very deep related, if anyone can help me will be very appreciated,
Thanks in advanced

Hi,
I have faced the similar kind of problem in BPC NW 7.5 SP5.
The main reason is when you are trying to send any data via input schedule, you will get this web server communication issue.
1) Check if any thing you are calling script logic under default.LGF. Exclude the logic out from default and test it.
2) Process all the dimensions in application
3) Perform Lite optimization and check are there any errors.
4) Finally check BPC COM+ services and check if any service stopped and also check osoft send governer service in microsoft services.
5) Diagnoise usign server manager.
6) Try input some thing in apshell and check if u face the same web server communication error?

Conversion Error: I/O error while communicating with native process

Hi,
I am trying to use Oracle Outside In Technology Image Export for conversion of images. I am trying to run the example ExportTest that comes with the downloaded SDK.
I get the below error while running the ExportTest example.
Conversion Error: I/O error while communicating with native process .
Am I missing any settings?
Please guide to the right forum if this is not the one for posting queries on Oracle Outside In Technology Image Export.
Thank you.

Hi Revanth,
I am using Image Export 8.3.7 and I am trying to run the java class "ExportTest" that is in the location sdk\samplecode\ExJava\Examples\ExportTest\src of the download.
My input folder has one jpg - puzzle.jpg (this is just a simple jpg), I am trying to convert it to TIFF. ExportTest.java uses the classes in Export.jar . Export.jar is located in the sdk\samplecode\ExJava\Examples\ExportTest . You can see source files of the Export.jar at location sdk\samplecode\ExJava\Java API\src of the download. I am running the 'ExportTest' by providing the arguments (input folder, output folder and ix.cfg - this file comes with the download). So now when I run this class I was getting the error I mentioned in this post. Inorder to find more details about the error I modified the 'Export.java' (at sdk\samplecode\ExJava\Java API\src\com\outsideinsdk) just to printStackTrace when the exception occurs and rebuilt the 'Export.jar' and ran the 'ExportTest.java'.
And below is the stack trace that I got :

An error occured while communicating with the web server

hi Experts
Im having a problem with bpc when i try to send data in an input schedule
message error prompt
"an error occured while communicating with the webserver"
Any body encounters this?
Thanks

Hi,
I am from support team, so this is the method how I troubleshoot this kind of issue.
First, I would like to say that this error message in BPC for Excel is a very common error, and it means nothing. Please move on the following steps:
1. Reproduce the issue again.
2. Logon to ABAP side, go to RSA1. Enter OBJECT=UJ* and SUBOBJECT=UJQ.
Note: UJQ means query related. The same, you can use UJD to filter all Data Manager's activity.
3. Under UJQ, you will find the log, which you reproduced in step 1. It must be shown as Red. Double-click it. See what the error message is.
4. Besides the error, right-side, you will see a Details button. Click on it, and another window with MDX Statement will show up.
5. Copy the MDX statement out for next usage.
6. Go to another T-code MDXTEST (this is a test tool for MDX statement).
7. Copy the MDX statement into MDXTEST, and run it. (find the run button at above).
What is the error message?
Based on my experience, if this is a Time out error, related to MDX Paser, you can try note:
1032461 MDX parser does not start
If not, it must be a specific error. Need to check further, accordingly.

An error occurred while communicating with the scanner canon mp640

Since 3 weeks I have this error *An error occurred while communicating with the scanner" when I tried to scan some document.
The all in one CANON PIXMA MP640 is connected via WIFI to my network and the printer works without problems.
I have repaired the disk permission but I have the same problem.
I have also removed the Scanner only from the system preferences and re-installed the software CD from CANON, no changes.
Do you have any idea about this type of problem? and help me for a solution?
Thanks a lot for a reply
Amedeo

First, delete the scanner again. Then I would suggest downloading the latest version from the Canon website.
http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/pixma_mp_s eries/pixma_mp640#DriversAndSoftware
Select your OS and download/install.

I'm trying to scan but instead of the scan a message comes up from PS saying "An error occurred while communicating with the scanner." help- I cannot scan!

Problem of communication with compactrio

Hello,
I am working with a compactrio 9014 and labview 8.5
I have a problem of communication with my compactrio. I acquire sound with NI 9215 and transmit points from the fpga VI to the VI on the real time target at a rate of 10Khz. On the VI on the RT I have two loops, one determinisic running at a speed of 10Khz (0.1ms) (in this loop I will do my signal processing) and one non-deterministic running much slower (20ms) to communicate data to my computer. To communicate data to my PC, I used shared variable.
The problem is that if I run the VI_RT, I loose immidiately the connection. I think that is because the VI is taking up all of the execution time of the
processor and is starving out the communication loop that is used to
send data back to my PC.
Because of this problem, I try to configure my compactrio to automatically run on startup of my cRIO. So I follow the steps I have read in another message in the forum posted by MattP
To make your application (RT host VI and FPGA VI) run automatically on startup of your cRIO, you will need to do the following:
1. Download the FPGA VI to the flash memory on your cRIO. If
using LabVIEW 8, right-click on the VI in the Project Explorer Window
and select Download VI or Attributes to Flash Memory...
2. Build an executable out of the RT VI. Under your RT target
in the Project Explorer, right-click on Build Specifications and select
New>>Real-Time Application. Select the source files necessary
for your application and any support files to be included. Click Build.
3.. After building the RT Application, you will find its entry
under the Build Specifications folder in your project. Right-click on
the application and choose Set as startup. Right-click again and
choose Deploy, which will download the application to your cRIO.
With this procedure, I thougt that I can run my loop faster because I don't have the RT VI open on my desktop (PC), so the PC don't have to synchronise the VI. But when I startup my compactrio, I loose connection with the target...
So, what is wrong with my project? Is it possible to run a loop at 10kHz on the real time processor and communicate in the same time (but every 20ms) data to my PC. Can someone explain me the right procedure to do that at this frequencies?
I have attached my project and hope that someone can help me.

Hello,
The method you use in your application to transfer the data from the FPGA to
the RT Host use the Front Panel Interactive Communication that write/read the
control/indicators of the FPGA VI. This method provides also risk of Race
Condition and use uP resources.
To avoid errors in data caused by race conditions and use less processor resources,
I suggest you to rewrite this part of your application with the method
DMA transfer from FPGA to Host.
You will find some good tutorial at the following address.

is the Best Method For Synchronizing a LabVIEW FPGA and a Host Interface VI?

Error on timesheet submission "An error occurred while communicating with the server.

Hello, we have many users who are encountering errors submitting timesheets following our migration to Project Server 2013 (SP1 April 2014 CU). The error is:
An error occurred while communicating with the server. Check connectivity with your administrator to determine whether further action is necessary.
This follows the specific timesheet, if I open a delegate session on my machine, I can reproduce the error. However, simply deleting and recreating the timesheet has resolved it for many users, at least until the next timesheet submission.
Has anyone seen this sort of widespread behavior and have a solution beyond deleting and recreating the given timesheet?
Thanks!

Hello Joncantrell
I just ran into issue and found a way to resolve, though it may not be the best. I think it is a bug, but here is how I fixed it.
1) Delegating as the user
2) Deleted the timesheet
3) Going line by line, I check each task that had a status of "Not Submitted" and "Send Progress for Select Task".
4) The error came up only for one task.
5) Open that schedule, remove resource from task, saved and published.
6) Deleted and recreated timesheet
7) Submitted timesheet and processed normally.
I hope this helps

MAX don't release LAN connction while communicating with Agilent 86122A

Dear guys,
Yesterday I met a communication issue while talking to Agilent 86122A via LAN.
It showed I cannot run MAX before launching LabVIEW; otherwise I'd have trouble in send commands in LabVIEW.
I doubt if MAX MAX don't release LAN connection while communicating with Agilent 86122A?
Please advise,thanks.
I debugged as below:
1, Ping the IP of Agilent 86122A shows internet is OK.
2, I restarted the instrument, LabVIEW reported the same error code.
3, I restarted PC, launched LabVIEW first and run the code (*IDN?), everything is OK!!!
4, Again, I send *IDN? With MAX, and it seemed to be OK.
5, hit x to close MAX and then run the same and simple code (*IDN?) in LabVIEW, but it reports error code -1073807346.

Caglar,
The documents you mention ahould include the proper prcedure for using this hardware in LabVIEW. Here are my recommendations:
The version of NI-VISA you mentioned is not valid. The most recent version is 4.6.2. I would recommend ugrading if you do not have this version. After the upgrade,ensure that tulip is enabled as well as the other settings and see if this helps.
When talking about the instrument, the biggest concern that usually is relevant with 488.1 is that it will not respond to *IDN?. In your case, it looks like it does, and should work as 488.2 is backwards compatible. It seems to me, the issue is still with the 82357A, and we have not yet reached the voltmeter.
In order for NI-VISA to work with your device, NI-VISA must be the primary visa driver.
Hope this helps, let us know how the upgrade turns out. If you continue to have issues, take some screenshots of the preferences in MAX and upload them on the forum.

"error occurred while communicating with scanner" mac os x 10.8.2 with new hp 6700.

device will not scan to computer. returns "error occurred while communicating with scanner". this error returns from the print/scan settings, from image capture and from the HP scan utility. the printer will copy so the scanner will function to some extent. it is brand new. on a wireless network. prints fine
OS is fully up-to-date, drivers are current, downloaded from HP and installed rather than using CD. device has been unplugged from wall, computer restarted, printers cleared and reinstalled.
any other ideas?
some more info...
if a sheet is placed in the scan feeder, the scanner illuminates and makes a ping sound.
firewalls are off
router has UPnP on
old printer, an hp6500, worked fine with identical setup
and a further note as I try to solve this...
the webscan function works from the printer web server
HP Utility does not have a Scan section. HP Utility Applications has Scan 3. this does not work

Hi BetterL8,
I understand your frustration. The software you are using was designed for the older operating system not for Mavericks. There has not been software released for the c310 that is compatible with Mavericks therefore, you will be using the Apples Print and Scan not the HP Scan. Because you have this old software still on the computer, I recommend you uninstall it and download the Apple Software Update. Follow the instructions below:
Scrub
Open the Applications folder > HP or Hewlett Packard folder > HP Uninstaller
Click continue, click on one of the printers in the list.
Hold down Control, Option and Command
While holding the three buttons down, Click uninstall.
Reset Printing System
Click the Apple icon ( ), and then click System Preferences.
In the Hardware section, click Print & Fax/Scan. The Print & Fax/Scan dialog box opens.
Right-click (or Ctrl +click) in the left panel, and then click Reset printing system…
Click OK to confirm the reset.
Type the correct Name and Password.
Click OK to reset the printing system. The Print & Fax dialog box shows no printer selected
Note: This will remove all printers in the print and Fax/Scan, any printer removed can be re-added later by clicking the plus (+) symbol
Repair Disk Permissions (this is good measure to ensure non of your permissions differ)
On the Dock, click Applications, and then click Utilities.
Double-click Disk Utility.
Highlight your hard drive/partition on the left (by default this is "Macintosh HD").
Click the Repair Disk Permissions button at the bottom of the window.
Once the repair is complete, restart the computer.
Restart the computer.
Check for apple updates
Connect the USB cable if it is not already connected
Click on the Apple icon
Select Software Updates.
Restart the computer.
Leave the printer on and unplug the power cable, reconnect after 1 minute.
See next post for further instructions....
