Form will not question the existing record
I am creating a page of user preferences based on a table that contains a record by the user, with the primary key = user_id.The form creates the record fine. If I exit the screen and return, however, he does not get this recording existing.
The form contains:
-A Point of Application called GLOBAL_ID
-A calculation Application called GLOBAL ID with:
Calculation Point = * on the new Instance *.
Calculation type = SQL query
Calculation = select f_get_id from double
-A process page called line of SZBRPRF with:
Process = * load before header *.
Run the process = once per Page visit...
Element that contains the value of the primary key column = * P1_USER_ID *.
Primary key column = * USER_ID. *
DML Fetch Mode = Memory Cache on Fetch
Where the Runtime = * = USER_ID: GLOBAL_ID *.
Success message = * read record for & GLOBAL_ID.*
-L' P1_USER_ID element has the following attributes to be defined:
Source type = * column database *.
Source of value or Expression = * USER_ID. *
Default value = *: GLOBAL_ID *.
Type of the default = * PL / SQL Expression *.
When I opened the page, the success message (recovered record for + 389 + is displayed, but the values are not.)
It seems that GLOBAL_ID contains the value I want that it contains, at the time where extraction is performed, but the record is not found?
If I enter a value in one of the fields and click on create, I get an error of unique constraint.
I also confirmed, through SQL * Plus, recording existing in the database.
I still think that the problem is with the field of P1_USER_ID and have tried various combinations, but it still does not work.
Any suggestions would be greatly appreciated.
Laura - please change your handle to something easier to read and to put your first name in your profile for us help. Thank you.
Calculation = select f_get_id from double
If f_get_id uses APP_USER to determine the file ID, you must move this point code definition process after authentication of the authentication scheme instead of use a calculation sur-nouvelle instance.
-A process called page line of SZBRPRF with:
Process = * load before header *.
After the cessation of header is a good cooking for ARF process
Where the Runtime = * = USER_ID: GLOBAL_ID *.
This seems redundant. I would like to delete it.
-L' P1_USER_ID element has the following attributes to be defined:
Source type = * column database *.
Source of value or Expression = * USER_ID. *
Default value = *: GLOBAL_ID *.
Type of the default = * PL / SQL Expression *.
The path of fires of ARF process before any point of form (as a default) attributes are evaluated. In addition, if the element of PK is null, the ARF process is not pick anything (the message of success of process notwithstanding).
I still think that the problem is with the field of P1_USER_ID and have tried various combinations, but it still does not work.
I think that a calculation before heading to set P1_USER_ID is your best bet (as Dimitri proposed). Make sure that this event fires before the RFA process.

Write that VI PNG file will not replace the existing file
Hi all
I use VI file PNG write to store the graph in a png file. I am able to save the file with a specific file name, which includes the date, model number, serial number etc.. Once the chart is saved as a png file, if I make changes in the graph (as autoscale, turn captions etc.) and try again to save the file with the same file name, write PNG leader VI does not save the changes I made on the chart. I'm looking at the timestamp on the windows Explorer, but it is not updated. I opened the VI itself (which is write protected) to see if it generates an error if I provided the same file name, but it does not generate an error.
I don't know if I am missing anything.
Can you people please help me find a way to replace the existing PNG file?
I'm using LabVIEW 2013 on Win 7 machine.
p.s. I use the second method mentioned in this article:
http://digital.NI.com/public.nsf/allkb/5AE4ADCBB65A6D8F86256FBF007A1AC1
(Programmatically with the Get Image method).
Thanks for your help

Explorer Windows cannot update the timestamp in the display immediately, or you might be looking at creation time, which doesn't seem to change when you replace a file.
I can say that I saw a similar question very recently (he was also PNG, even if it's not really relevant), and here it certainly crushes - http://forums.ni.com/t5/LabVIEW/LAVA-snippet-overwrite-keeps-old-date-time-of-png-file/m-p/3257059#M...

CS6 upgrade will not identify the existing Installation of CS5.5
I have a legal copy of CS5.5 Master Collection for Windows on my PC. It is installed on an SSD, mapped to the B drive for speed. Just purchased and downloaded CS6 Production Premium for Windows. Entered the serial number, but the installer could not find the installation of MC CS5.5 (itself an upgrade to a version full of CS5 MC) so he prompted me to the S/N of a qualifying product. I entered my CS5.5 MC S/N, and the installer says that it is not a product calling. What gives, and how do I solve this problem and get the CS6 switch to run? Thank you.
You are partially right. I contacted Adobe support and they were able to help me with a special code. Of course, it's sort of downgrade (but I use no more product non-ProdPro like InDesign) but it is legal and I did qualify for the upgrade price. Choices in Setup included CS 5.5 MC, so that Setup is misprogrammed so that is not supposed to happen. So now I moved on, no worries.

PDF form will not calculate the selected fields as soon as there is a numeric value entered.
All selected fields and as soon as there is a digital value entered, the total field displays nothing, not even a 0. It worked yesterday so I'm not sure what the question is today. I hesitate to do it again because this form has a ton of fields.
Things to check:
-That there is no error message in the JS Console
-The field calculation order is correct (IE, that there is no 'delay' in the order in which the fields are correct results)

New facility will not load the existing catalogs

What Miss me?
Thank you
Jim
Jim,
Now that your problems seem to be attributed to a permission problem on your drive/folder containing the catalogs, I suggest you to clean up the "mess" we started last night while doing research:
- Close LR
- Rename the newly created presets folder "... \Adobe\Lightroom" to something like "... \Adobe\Lightroom.new."
- Rename the original folder "... \Adobe\Lightroom.old" to "... \Adobe\Lightroom".
- LR to start as administrator
In doing so, restore you your presets folder to what it was before the investigation. If LR is running to your satisfaction, you can delete the folder "... \Adobe\Lightroom.new."

Fuze 4 GB will not recognize the change of information tracking
Right then, I had some problems with my Fuze MP3 player. When I download the new music on the device, the ID3 tags all come out the way they are supposed to. However, if I remove the music that is on the drive and replace it with the same tracks with ID3s update, it will not recognize the change of title, album, or artist, if the song file will be updated. I know because I had problems with the songs with the same name or accidentally given songs the name of another song, which resulted in incorrectly labeled music.
I tried to format the drive, I tried to remove the music manually in the file system, I tried to change the USB mode and delete the file that I said holds the ID3 data, and I tried all the possible permutations of disconnection and let the Player recognizes the changes. This includes the removal of all the music in the player, disconnection of the latter, confirming that there is no music on the system, to change the USB mode, deleting the file with the ID3 information, turning the rear USB mode, reconnect, put my music on the device, and the problems have not been resolved.
It is likely, it is just to be fickety, and there is something I'm don't is not right, but it's the second "rocket" I've owned - I love the model and went up to return a Fuze + in favour of the former model - and one has never had this problem. I'm willing to try anything within reason to solve the problem, so I hope someone can point me in the right direction.
In fact, the problem was not as expected at all. I think it turns the problem is Windows Media Player, which I only use to sync my music on my MP3 player, had a library with outdated information. So after the Player update multimedia, I refreshed my library recordings and everything worked as you wish. I just to make sure that if I make changes to existing songs in my library.
Thanks for all the help, guys, guess it was on my end.

Windows 7 will not recognize the dvd drive
Windows 7 will not recognize the dvd drive, although it worked well for more than two years. Now I can't access it to install new software.
It will not be displayed in the Device Manager, bad shooters to say it is not connected or is, tried Fixit fix (could not as "not applicable to your computer update"), uninstall iTunes (in the case of a conflict - even if it worked with the DVD of > 1 year), etc., but still cannot access the DVD.
It's obviously a known issue, given that a support page - http://support.microsoft.com/kb/976187 that recommends the fix or manually disable ALPM active power management. If it of a known issue, why is not included in the updates and that I have to disable ALPM power if management it worked ok before?

PS5 will not change the date registration
PS5 will not change the date when I save a document I'm working. I tried save as and save and it keeps the date of the photo, in this case, a scanned image that swept the 09/07/11 @ 15:49. I saved many iterations of the PhotoShop photo and the date remains the same. I tried it with other photos and even once, it retains the original date. If I open in AI5 and save it, he recorded with the current date. Am I missing something here?
I use the current build 12.0.4 x 64, Win7 Home Premium
PAM
Chances are Windows found the folder a folder "photo", and explore does NOT show you the date of the modified file.
Personally, I hate having "automatically" selected multiple views for me, and I tweaked my copy of Windows so that it always shows me the "General items" view all records, be they full of photos or music or something else.
You can check this by clicking on the name of the folder in the Navigation of Explorer (left), and then selecting Properties. On the Customize tab, see what it says in the "optimize this folder for:"selector. ". If it is different from the general items, change it to general Articles. This gets you a good "Date Modified" column, indicating the date of the file.
If you want to make a permanent change to Windows 7 (so all new folders are displayed in the form of General items in the folders, and automatic display selection is disabled), a value can be added to (or changed in) the registry as follows:
Registry key: [HKEY_CURRENT_USER Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell]
Name of the Data Type value
FolderType REG_SZ NotSpecified

Preview will not open the hyperlink to the specific DOI PDF format
Hi all
I generated a PDF of markdown by Pandoc (with xelatex as the tex engine); the PDF document contains hyperlinks URLS. One of hyperlinks is a specific address of DOI: doi:10.2307 / 488160. In Adobe Acrobat Reader, this link accurately opens in Firefox (my default browser) and is then solved using a DOI Manager that I have in firefox. Overview, however, will not open the link. When you click, you get just that boing sound error.
I believe this may have to do with the security aspects of preview that are cooked in the program - what kind of overview is able to open external files. There was a discussion on this here, but it is not exactly answered my question: https://apple.stackexchange.com/questions/119299/why-preview-app-refuse-to-open-local-lien-dans-un PDF file.
If this isn't a connected safety side overview, is it possible to adjust preferences overview way treats the links that start by "doi:"? Other ideas.
Note: I know there is a better way to include the Doi in Tex docs (with the DOI package) as the starting URL by "doi:" but I like to keep my Markdown as clearly readable as possible and does not markup inside latex. I might add a Pandoc filter for this - but I would rather understand the problem of this end if possible.
Thank you!
... One of hyperlinks is a specific address of DOI: doi:10.2307 / 488160.
This address SHOULD you present is only the persistent identifier. To make a connection, precede the string with the http://dx.doi.org/ url so that your example is http://dx.doi.org/10.2307/488160
Basically, the url is a program of resolution. By including a DOI link, there is no need for the Manager/addon Firefox DOI. You can have the text that is displayed differs from the URL. In other words, the manuscript shows doi:10.2307/488160 but the underlying url link is http://dx.doi.org/10.2307/488160
