SystemDefinition: NullReferenceException when creating an Alias

Hello,
I'm programatically creating a SystemDefinition and I have the problem that I cannot create an Instance of the "Alias" class when using the (String, String, String) overload. No matter what texts I pass as arguments, I always get a NullReferenceException saying "Object reference not set to an instance of an object".
What's wrong?
Thanks

Hi,
basically LabVIEW and other text based programming languages are always referencing to the .NET API of VeriStand.
Please check the following link, they create an Alias for a custom device

Here is also another example basedLabVIEW Walkthrough: Modifying Models in a System Definition File on LabVIEW
Are you able to create the Alias in LabVIEW? If so, please use the same .NET calls in Iron Python

Shortdump "ITAB_DUPLICATE_KEY" in SICF when creating an alias

Hi
I'm trying to create a reference to the WSHANDLER service in SICF, on a WAS 7.00 system (IDES), but when i'm switching to the tab "Alias Target", the system generates a Shortdump (see below).
Have any of you experienced/solved this problem (It's on an IDES System so i'm afraid that help on the OSS isn't very likely )
I have found a post from [mani sahay,|DSWP;, with at reference to OSS Note 1042052, but it doesn't seem to exist
Any help on this issue would be very appreciated

When is an Alias created?

While helping a friend I found a folder full of aliases of jpgs. She thought they were the real images but in fact the real images were not on her hard drive. I know an alias is created when you drag a file to a CD to burn but these were in a folder on her hard drive. I did a searh on Alias here, but not an answer to the basic question, "under what circumstances might one end up unknowingly creating an alias by simple drag and drop". I doubt very much she did any dragging with an option or command key combination. Searching for the file names showed the originals were not on her computer. She often burns CD and often copies images from a compact flash card mounted via a CF card reader but I can't imagine she mounts a cd, copies original from the mounted CF card to the CD and then drags the alias to the hard drive... What other ways might somebody end up with a folder full of aliases and no originals on their HD ?

Most likely she thought she was copying the .jpg’s from another computer to a CD by dragging them without holding the option or command keys, which copied only the aliases and then copied that folder of aliases to the computer.
The only other ways I can think of would be by 1) dragging the files to the CD (making aliases), dragging the folder of aliases back to the computer, and the deleting the originals (unlikely)
or 2) making a new folder, making aliases of the files (command-L), dragging the aliases to the new folder, and deleting the originals (also unlikely).
With either of the last two it may be possible to recover them from Time Machine. For the first, and most likely, find the computer with the originals and copy the files (not aliases) to a CD and move them to the desired computer.

Finder crashes when I create an alias on my iDisk

This is sort of weird, and I believe it may have started with the last OS update. When I create an alias by control-clicking or right clicking on a file that is on my iDisk, Finder crashes to permanent beachball. It does this every time. It can be restarted with the force quit menu.
But this is kind of a pain, and I think it's possibly a bug in the update? I store my frequently-worked files on my iDisk and create aliases on both of my computers' desktops to access them. The only way now that I can create these aliases without crashing is to drag the file off the iDisk, make the alias on my desktop, and then drag the real file back to the iDisk.

Yes, I do know - thanks, Kirk. And I used to use that feature. But now, I have so many files on my iDisk that it takes too long to sync the whole thing, particularly on my Macbook when I'm away from home on a hotspot or slow wireless.
I don't want to take the older files off, because I need to reference them occasionally so I want to make sure they're available everywhere, even when I might not have my laptop and be on someone else's unit. It's just the two or three active files I am working at the time that I put on my desktop as aliases.
I suppose "back to my Mac" might now be an option for the older files, since I now have an Airport Express. It previously would not work on my cable modem connection, though.
In any event, I used to be able to create the aliases exactly the same way, and now it crashes Finder. So I'm kind of suspicious a bug came in on the last revision.

Hi ,
Please verify the Information Store service is started.
Distribution Group and contacts both have no mailbox in information store. So you can create them.
And now, we may need to verify if the mailbox database is mounted and we can get its information.
The following similar issue for your reference.
Cannot execute Get-MailboxDatabase cmdlet:<//span>

By the way, do you choose which mailbox database you want to store when create mailbox ?

Create an alias to run a plug-in?

I'd like to create an alias on my desktop that would run an Automator plug-in.
Is this possible?
I find it clumsy to have to right-click my desktop and navigate three menus to get to it.
Thanks in advance.

Indeed I could create an alias to the workflow, but then Automator has to start and then I have to click the Run button and then quit Automator when that's done.
I just want to double-click an alias rather than right-clicking on my desktop and navigating the appropriate menus.
My workflow does not prompt me for any input when it runs; I've told it to use the same input every time (Get Specified Finder Items (External Harddrive) -> Eject Disk -> Put Computer To Sleep (this is a Cocktail action)).
At the moment I've saved the workflow as a plug-in for the Mac's script menu, which isn't as bad but still not the best.
I've discovered that you can run Automator workflows via Terminal, so I'm currently investigating if this could lead to the answer...

TS4002 Can't create any alias in iCloud mail, see message "Cannot save alias.

Can't create any alias in iCloud mail, see message "Cannot save alias. This alias cannot be saved at this time". I tried different variations at different dates (I thought this is temporary issue) but this not helped me. Perhaps some of you have resolved this issue and can tell me how I can do it?

Do you see in account settings two email addresses - with "@me.com" and "@icloud.com"? Or only "@me.com"? In second case just wait - your account will be updated in some time. I've waiting from summer and my account was updated in one day as soon as I've start this discussion When your account will be updated - you will see in preferences two addresses, with "@me.com" and with "@icloud.com".

Problem in creating HTTP alias in WAS

Hi,
i have followed the steps to create the http alias mentioned in the below link
[Creating an HTTP Alias in WAS]
when i click on the HTTP Provider in visual administrator, "Error while loading service HTTP provider" is displaying. after that i have created alias as
Alias : testexample
Path : E:usrsapj2ejc00j2eeclusterserver0 estexample
and saved the properties. when i see for the folder "test" under E:usrsapj2ejc00j2eeclusterserver0, i did not find the folder which was i created.
how can i make the folder visible and to add a text/html file in that.
regards,
vv.

Hi,
the first thing is that you have to create the folder manually on the filesystem (in your case E:\usr\sap\j2e\jc00\j2ee\cluster\server0\test\example => test and example) Then you can access this file.
Maybe you should start with only a name without a "\". Create the alias "test" and create a folder e:\testfolder. Then point the alias test to the folder testfolder.
That should help,
Holger.

Creating an alias - is this a bug or what??

Please let me know if this is a bug or a "feature"!!! As I understand things (a few changes since OS 6.0.4 in 1989...) there are 4 ways to create an alias when one is in a folder. For example, I'm in my Applications folder with 300 items in that folder. Generally I put my aps into a folder with the name of that app and the word folder. (I used to use ƒ but read that Unix doesn't appreciate that symbol)-- OK back to the main point: ALIAS creation - 4 ways I know to do this:
1. I right-click and choose Make Alias with the folder or icon selected
2. I hold down the option and command keys and select the folder or icon, then drag it just a bit and voilà - an alias.
3. I choose the folder or icon I want and then do cmd-L to create the alias.
4. I go to the file menu after selecting the folder and choose Make Alias
GREAT all 4 work (is there a 5th way?)--
BUT when I do choices 3 or 4, then instead of everything staying in place, the alias is created and then the screen jumps to the very top - to the "A" or numbered labeled folders / apps!
NOTE: My apps folder has the view choice to ARRANGE BY NAME. If I change this to none - then cmd-L or Make Alias just makes the alias in-place!
BUT choices 1 and 2 also keep the window of my apps folder in the same location EVEN WHEN IN THE ARRANGE BY NAME mode.
Again - is this a bug or a feature? Certainly annoying to make an alias and then have to go back and search for the alias... And note: If arrangement is SNAP TO GRID then choices 3 and 4 for creating an alias also have the screen jump to the "A" folders, i.e. the BUG!
Any comments appreciated - this is a real pain as I keep many of my folders organized by SNAP TO GRID or ORGANIZE BY NAME.
Best regards,
Steve Schulte

Thanks for your fast reply! There are 3 issues and I'm mainly concerned with #3- but I likely confused everyone with my long post - so let me try this:
1. Moving Apps out of the Applications folder: You are right, it is best to keep the apps in the Applications folder. Especially Apple's applications - for the update and maybe other reasons and I do that.
2. Creating an alias and where does the alias go: That's right, it has the same name and just the word alias added to the end so YES it stays right next to the original (especially when the folder is in the Arrange by Name view). So no problem there - mine is the same.
3. Third issue is really my only concern: The act of creating an alias by cmd-L or the menu: In a window that scrolls, i.e. with many apps or several apps with large icon size (I should mention I'm talking in ICON view here)-- when you make an alias, the window automatically scrolls to the very top. So if you have a folder with 300 apps in it and you make an alias of ZEBRA FOLDER, then the alias is in the correct place but the window scrolls to the top (AARDVARK Folder or whatever).
*ADDITIONAL INFO:* After several restarts - yup, this is now NOT happening very often. Mostly the window is NOT scrolling so perhaps I'm wasting your time and others with this post. Let me recheck the next few days and then post again- especially if the problem has disappeared... which it seems is the case... (I should remember to restart 2x when anything unusual before posting!)

I graceful with you if can help me, thanks and regards.

you dont create a infopack on DTP rather you need to create on datasource.
rightclick on datasource - create infopack (when you schedule this infopack, it will load data only till PSA. From there you need to use DTP to load to further data targets)

URL checksum when using page alias

Hello to all.
I'm using Apex v4.1.1.00.23, and I'm having a problem when using page aliases in URLs.
When creating a list with links to Apex pages, if I use a page alias, then no checksum is generated. I tried this using the "classic" way to create list entries (i.e. "Create list entry" and entering desired values in the "Target" region), and also using a dynamic list and an SQL query.
For example:
SELECT 1
,'First page'
,apex_util.prepare_url( 'f?p=&APP_ALIAS.:1:&APP_SESSION.::NO:1::', p_checksum_type => 'SESSION')
FROM DUAL
UNION ALL
SELECT 1
,'Second page'
,apex_util.prepare_url( 'f?p=&APP_ALIAS.:second_page:&APP_SESSION.::NO:second_page::', p_checksum_type => 'SESSION')
FROM DUAL
For the second link, I always get "Session State Protection Violation", but the first one works fine.
Both pages have the "Page Access Protection" set to "Arguments Must Have Checksum".
I tried to set up an example on apex.oracle.com, but it seems that in v4.2 this problem is fixed :)
So, is there any way to use page aliases while session state protection is active?
Thank you for any help that may come by,
best regards.

Indesign creates an alias file

Indesign creates an alias file when saving larger files on a Mac with Windows Server 2008. Does anyone know a fix for this?

Launch terminal and use this command /usr/bin/SetFile -a a followed by the path name to the damaged file.
Something like
/usr/bin/SetFile -a a /Volumes/YourServer/ShareName/FileName.alias
or
/usr/bin/SetFile -a /Users/UserName/Documents/WIP/FileName.alias
The easiest way to get the correct path name is to launch Terminal and drag the damaged file to the command line, Terminal will create the correct path, now all you need do is paste the command in to the Terminal command line before the path and hit return.
I don't expect you will have this issue with InDesign files stored on your local HD, it most commonly occurs with files stored in a share on a Windows server.
Good luck,
Cheers

After creating an alias, the App Store application has disappeared from the Launchpad. Huh?!

So, I opened the Applications folder, then selected the App Store application and created an alias of it.
Now, when I activate the Launchpad the original app is nowhere to be found. The alias is there, but the application proper is not displayed.
It IS displayed (as well as the alias) in the Applications folder when I open that in the Finder.
I have no idea how to remedy this. Logging out and back in is fruitless. And a reboot makes no difference.
Any ideas, please? Any one? Bueller? ;-)

Yes. The alias works. And the App Store application (which is still in the Applications folder) also works.
Interestingly, I just tried a similar thing with the Adobe Reader app...created an alias of the application in the Applications folder. The same thing happened. The Adobe application disappeared from the Launchpad, replaced by the working alias. The fix for that was to delete the alias from the Applications folder. Then copy the Adobe app onto the desktop and finally copy it back into the Applications folder, answering "Replace" the original when prompted.
Of course, when attempting to copy the App Store app back into the Applications folder, the process cannot be completed because the OS says... “App Store” can’t be modified or deleted because it’s required by Mac OS X."

Creating an alias table

Hi all. I have a situation where I need to create an alias copy of a table and then pull information from both the original and the alian (the database creators built the table to hold different description, amount, and date info in the same fields when triggered by another field. Lovely)
Can I do this in Crystal?

I believe you can just add the same table twice to your report, and specify how they should be joined. I believe Crystal will put a "2" (or some such) at the end of the second table's name for reference purposes in the report.
Or, do what I usually do, and base your report off of an SQL command, something like this (MS SQL):
select orig.order_no, ref.order_no
from orders orig, orders ref
where orig.ref_order_no = ref.order_no
I rarely use tables directly, as reports tend to run faster when based on an SQL command that just returns the required data (as opposed to whole copies of perhaps several very large tables), so I could be wrong on the first suggestion...
HTH,
Carl
