Replace read character from file
HI,
I have updated my labview 2014 and have a load and save function wich not working on the new version.
It says that the read character from file is not supported any more.
How to i fix it to run in labview 2014?

Do you know about Snippets? This is what looks like a .PNG file, but can be dropped in a LabVIEW Block Diagram to become executable code. Find it on the Edit menu of the Block Diagram.

Hi,
I coded a program that reads a given integer. The integer represents a character location in another file. The program then opens a text file. The program is supposed to goto the integer laction and read 500 characters past that location. I am unable to get the program to goto the correct location in the file. If I give an integer value like 135159, the program goes the location it claims is correct, but it is not. Are there any constant values that LV uses when reading file locations? In my file there are 71 characters per line, 70 real characters and 1 line feed.

Find in other sequence_14.zip 258 KBThe problem is your offset doesn't take into account the file header or the end of lines. So, when you read from file, it includes all those characters. I wrote a little VI that will calculate the "true offset." Now, one point of confusion for me is that I had to enter the original spot (in your example 357750) to get what you said is the right point for the -500 spot. I would have thought I would have to take the 500 into account, as going 500 back also covers line feeds (in this case 7), but if you say that the spot you have is the correct spot, then do this with the desired offset not included.
You can avoid this by reading the file in, stripping the header, and removing all the line feeds. Your data should be one contiguous stream at that point. But, you will need to determine if loading the whole file to do this is practical. With this calculation, you can do it a byte at a time if you wish.

I Basically followed this guide [1] adopting it to arch.
That's where i got my nginx.conf from. Taking the standard nginx.conf that comes by install and replacing the server part.
After some searching I found the owncloud manual[2] with an example nginx.conf. Comparing that with my one I found some differences. Applying them works out fine.
I get now the owncloud page.
The systemd error still ocurs, but I think it does not matter to run the server.
Thanks for your help.

Bug: Keywords behave incorrectly after "Read Metadata from File"
(Happens in LR3.4 RC and probably also in previous versions... but I am not sure if it happened in LR2)
The problem seems tro be somthing like de-sync of database status and what we see on the screen.
1) Let's say we have a photo with keyword "abc"
2) Click in the Keyword List on the arrow around the "abc" keyword to show only photos with this keyword (single one), leave the filter on this settings
2) Save Metadata to File
3) Edit XMP in an external application, add new keyword "def"
4) Read Metadate from File
5) Now what happens is: The photos disappers from the screen as if it lost the "abc" keyword (weird), but if you look at the Keyword List, the "abc" keyword has still 1 photo attached to it. Also, if you release the filter and find the photo, it clearly has the "abc" and "def" keywords in the Keywording panel. And you can search for this keyword in the text filter (works correctly), but if you click on the arrow around the "abc" keyword, the photo is not shown.
6) If you restart the Lightroom, it will work correctly again.
I have an own application that is able to modify the XMP and the modifications may not be perfect, but in my opinion, this shouldn't happen when reading the metadata. If any developer is reading this, I can supply a file with original and changed metadata for debugging.
It would be great it this could be resolved.
Thanks!Please do report your find with the details you state (well done!) here: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform

Hello,
We are in perfroming the last dryrun of our CU&UC conversion.

I would like to read data from files in EJBS (Stateless Session Bean I think). I've heard that the EJB sepcifications don't allow to use the java.io package to access the filesystem. How can I resolve this problem? Possible solutions I've thought of are:
* Use a webserver to store the data
* put the files in a jar and access them using the getResource() in the classloader class
Could you comment on this plesae
greetingsThe specification states:
"An enterprise bean must not use the java.io package to attempt to access files and directories in the file system.
The file system APIs are not well-suited for business components to access data. Business components should use a resource manager API, such as JDBC, to store data."
From this I understand I cannot acces files directly, but it does not specifiy I can't use the java.io package at all. It specifically says not to use the java.io package to acces files and directories, they don't say anything about using the classes for other use.
however, a litle lower the specification states:
"The enterprise bean must not attempt to create a class loader; obtain the current class loader; set the context class loader; set security manager; create a new security manager; stop the JVM; or change the input, output, and error streams.
These functions are reserved for the EJB Container. Allowing the enterprise bean to use these functions could compromise security and decrease the Container�s ability to properly manage the runtime environment."
I'm not sure how to interpret this, but I believe this rule makes my solution invalid.
Please comment on this,
thanks -

ThanksThe code given to you as an example demonstrates how to open the file, read a line of data from it, and split that line into parts.
You are given the format of the file, and example data.
So - given that you know how to read a line of data from the file and split it into parts, and given that you know what the lines of the file look like - can you write out in your native language what you need to do, using "read a line", "split the line into pieces", "use the nth piece" operators, to process the file? If you can, then do, and convert that to Java. If you can't, then you need to back up and understand your problem better, then try to write out your solution in your native language.
If you run into any specific, technical problems come back and ask away
Good Luck

Bug: "Read metadata from file"
When I add GPS coordinates to a file (with the program Geotagger) and select "read metadata from file" to import the new metadata, a color adjustment badge appears on the thumbnail (even though I didn't adjust any colors). This only happens with files that have a cropping applied to them in Lightroom. If the file doesn't have a custom cropping the color adjustment badge doesn't appear. It happens with both JPG and CR2 files. Seams like a bug to me.
I'm on a 24" iMac 2.8 with 4 GB and OSX 10.5.5 / Lightroom 2.1It also happens with DNG. Anyway, I don't think it has anything to do with the GPS, but the issue has been around right back through version 1.x Try the following:
1. Select an image that has no crops or develop adjustments
2. Switch to Develop module
3. Apply a crop
4. Save metadata to file (Cmd+S)
5. Read metadata back from file (Metadata menu - "Read Metadata from file"
Please report what happens?
At my end the Crop badge remains but a Develop Adjustment badge also appears - IMO it shouldn't, but as stated above it has for a VERY long time. I'll bug it again and see what happens. -
Hi Everybody,
I wonder if Lightroom 3 offers a function that lets me read metadata from file for multiple images in a batch process. The reason is that I have changed the GPS information for quite a couple of my pics using the Geoencoding Support pluging from Jeffrey Friedl and let it write back into the DNG-file. Since I also flushed the shadow data I can't see any GPS information in my metadata table in Lightrrom even though the data are present in the DNG. Now the real question is: Is there a better way to get my GPS data into Lightroom than emptying the Library and reimport all of my pics?
Oh, and before I forget it: Yes, I have searched this forum - and a couple of others as well - and I found stuff about batch processing date/time information. However, the method presented there apparently does not apply to my problem.
Thanks for any information.
Have a nice day,
f.In Library Module, select Grid Mode. Select all images you wish to read metadata from. Go to Metadata>Read Metadata from Files
Similarly, you can edit time for time zone/ AM-PM issues, etc by going to Metadata>Edit Capture Time -
Reading Metadata From File Resets the Setting
I am using Lightroom 4 on MAC OS X Yosemite. I have done some editing on a picture in DNG format and then clicked "Save Metadata to File". I checked the XMP file with textedit and found that the change is indeed saved. But when I click "Read Metadata From File", it resets the pictures before any editing. Please, I need help to fix this problem.

I'm confused - I'm pretty-sure Lightroom 4 will not save changes to an xmp file (even if DNG is read-only, unlike Bridge) - it embeds the metadata in the DNG file. Did you mean you edited the DNG file with a text editor? Anyway, if you do have a .xmp sidecars to your DNG, I recommend deleting them, or renaming them (until you figure out what's going on anyway), then retry - any difference?
PS - last I checked, Lr will generate an error when saving metadata if DNG is read-only, but since you're having a strange problem, I'd definitely make sure they are not read-only.
Note: Lr WILL read metadata from an xmp sidecar, *iff* it seems newer than what is embedded. So, IF you have xmp sidecars that have a recent modification date, or *maybe* (I don't really know) if Lr was NOT able to successfully embed metadata into your DNG, it could be reading some incompatible metadata from the xmp sidecar - thus the reason to get it out of the way to test.. -
We use proxies in our work flow, pre-rendering certain comps before rendering out the final project. For the most part this works fine, but occasionally we'll get an error that reads: "Error (4) reading frame from file." It's always the same comp but it doesn't cause the problem in every project.
We use the quicktime codec with Tiff compression. Could it be a memory issue? Any help would be greatly appreciated. The error always pops up at the most inconvenient time -- of course.
Thanks,
JulianWell, if it's always the same file, then most likely one of the source footages is really damaged. The error not occuring every time mustn't mean anything. If the element in question is not visible at the given frame or AE doesn't do anything with it because it isn't required, naturally the error would not occur. I'm afraid the only way to track this down is to selectively disable/ remove the sources from the comps in question and render some test clips. Perhaps it would also help to check all the files used in the project in a "neutral" app such as external image and video viewers (XnView, VLC, MediaPlayer Classic...)

Read metadata from file cancel modifications !
Hi,
I use Lightroom 1.1 in french. I made some photo (in raw but in jpeg the result is the same) and import them in Lightroom with conversion in DNG. In Lightroom, in develop module, I crop, change contrast and som others.
After that, I geotag my DNG files with HoudahGeo. HoudahGeo write geotag in the file. So back in Lightroom, I make a 'Read metadata from file' ('Lire les métadonnées depuis les fichiers' in french) for having geotag in Lightroom.
Geotag are now in Lightoom, nice, but in develop history, I have a new line 'Rénitialiser les paramètres' !!! So I can't see all my modifications... Is it normal ?
Thank you
PS: Sorry for my english...I think you should test this with one or two pictures - import/convert, save metadata to file, geotag, read metadata. Also try import/convert, make small adjustment, save metadata to file, geotag, read metadata. In iView I often write metadata to DNG's that have been adjusted, then read the metadata in Lightroom - sometimes I add more data in iView and do more adjustments.
I have seen the problem you describe, but it has been with raw files which I have adjusted in Lightroom but haven't saved out the metadata. I have then created an xmp sidecar in iView, and read the metadata in LR. So the sidecar had no ACR/LR instructions. The result was that my adjustments were wiped out. What I suspect is that something similar is happening with your DNGs - that conversion creates them but doesn't write the ACR/LR fields.
So try a few alternative sequences.

Feature Request: save metadata to file, and read metadata from file.
Please have function to save metadata to file, and read metadata from file.
This would allow us to write cross-platform plugins that can assure data is up-to-date in the xmp, or modify xmp and have it reinstated in the catalog.
This would go nicely with the ability to save xmp for virtual copies, dng, and rgb formats.Perhaps someone with direct experience with publishing to Smugmug will chime in. Short of that, some thoughts on your issues:
Should I not bother to "Save Metadata to File", this seems to be what is messing up the SmugMug publish service?
I very much doubt that it is messing up the publishing. What gets saved to the file from the catalog is independent of what gets exported. Saving metadata to the file is generally a good practice (in case you screw up your catalog backups). Many, perhaps most, users set the preference Catalog Settings > Automatically Write Changes Into XMP.
I would have expected it to behave like an export which would write synonyms, exclude keywords that should be excluded, etc, which seems to work ok in point 6 above.
Yes, that's a reasonable expectation.
You may have done this already, but double-check: Right-click the Smugmug publishing service in the left-hand column of the Library, select Edit Settings, and in the Metadata section verify that you have Include: All Metadata set.
Did you download the Smugmug plugin from Smugmug? You might try this Smugmug plugin instead -- the author designed the publishing architecture of LR and has an excellent reputation.
Are the publish services more effort than they are worth? So I get SmugMug to work, what happens when I try Flickr?
I think many users find the publishing services are generally worthwhile. I publish regularly to Flickr (using the built-in Flickr plugin, which isn't completely reliable) and the Zenfolio plugin from Friedl. -
