How to save multiple snap shots in one file?

Hi,
I've been trying to take snap shots using a USB camera and save the
them into one file; however, I've had no luck with the saving part. Can
anybody help me with this problem? I've attached the code I'm using in
case anybody wants to take a look.
Thank You,
Molana

Camera Snap Shot1.vi ‏100 KB

Hi Molana,
If you are looking to save these images to file, you can use either the IMAQ Writefile VIs, or potentially the AVI writefile VIs. These VIs are both on the FIle I/O palette of the Vision Utilities subpalette. To write an AVI file, you <b>open</b>, write to, and then <b>close</b> a session, very similar to most processes in LabVIEW.
I also noticed in your code that you are enumerating your USB cameras and closing the camera session all within the while loop. This adds a great deal of overhead and time to your acquisition process. I would recommend moving these processes outside of the acquisition loop, such that they occur once before and once after the snaps.
If you are still having trouble acquiring, I would recommend that you download and install the NI IMAQ driver. It includes examples for snapping and saving images with NI IMAQ. This process is extremely similar to that which you would use in NI IMAQ for USB.
Hope this helps!

How to save multiple new entries in one shot?

Hi,
I am working on a pretty complex Create form. So apart from the standard form fields to allow user to enter the data, one of the sections in this form is a table which allows user to create multiple entries for this entity. And when hitting the "Save" button in this form, it will save all the data plus the multiple entries defined in this table.
Is it possible to create multiple new entries in a table, and then save all of the new entries at the end? My experience so far is only create and save one new entry at a time.
Any sample?
Please advise.
Thanks.

Yes, I am using ADF BC.
Let me explain more in details of the scenario:
I have a table with "Create New" and "Save" button. The "Create New" button's ActionListener is set to "#{bindings.CreateInsert.execute}", and the "Save" button's ActionListener is set to "#{bindings.Commit.execute}".
When the "Create New" button is hit, a new row shows up in the table to allow entering data inline. When the "Save" button is hit, it got committed. I would like to allow user to create multiple rows before committing. But currently, after I hit "Create New" button, then enter data, then hit "Create New" button again without committing, it gives error.
Since this table is part of a form with other fields, I would like to save/commit it until everything in the form are completed, including creating multiple rows in the table.
Any ideas how to achieve this?
Any comments are appreciated.
Thanks.

How to apply multiple automator workflows to one file

Hi everyone,
I've set up a few workflow applications to automate the process of making packshots from PDF files. The way those roughly work is they create a temporary copy in a folder, open a Photoshop droplet that executes all the actions on the file, and then save the finished product in a "finished" folder.
However, we frequently need to deliver multiple packshots made from the same file. I was asked to make one automator app that allowed us to drop the PDF version on it, resulting in the multiple types of packshots in the "finished" folder, together with the original PDF.
The way I have this set up right now is as follows:
1) Copy the original PDF file to the "finished" folder
2) Execute the first automator app
3) Execute the second automator app
This seems simple enough, and does work in 10.6.8. When I try it on a different computer in our studio though, with 10.7 installed, I get various errors:
- Sometimes it says an error occured within one of the automator apps, while the app works fine when running it seperately (on all computers).
- Sometimes it says something like "An error occurred while converting the data" when moving on from the first application to the second application
- Sometimes I'll get an error message in the log, saying:
*** -[_NSArrayl objectAtIndex:]: index 0 beyond bounds for empty array
What I got from this is that it's actually not getting the right input it requires (or not getting any input, since it's an empty array). However, the previous task is set to "return the task input" (our systems are Dutch so excuse me for any discrepancies in translations please), and the resulting output that I get seems to be what I want the next automator application to use. Below is a screenshot of the error message:
What I've tried:
- I read somewhere that the newer versions of Automator require the action "Retrieve selected finder items" between them. I've tried using this in various ways (between all other actions/tasks, only before the second application to be run and before both applications to be run), but with no success. The problem I have with these is that, during the applications, it moves the files around, thus apparently selecting those folders as well.
- Building an entirely new workflow on the newer system
- Using "Start application" instead of "Execute Automator workflow". This results in Automator saying that it did execute the workflow while nothing happened.
- Using "Ignore input" for the second application. This also results in Automator saying that it executed the workflow while nothing happened.
So right now, I'm pretty stumped as to how to get this combination of apps to work in 10.7. Any solutions or workarounds are most welcome.
Thanks in advance!

Yes, angelanna. You can merge or split your video file via FCP sequence.
ahaah, maybe I think angelanna would like to get the resulting file with MTS format because he mentioned “No need to be compressed”. Are you asking for this, angelanna?
If so, a simple MTS files managing and editing tool is needed. Maybe you can have a try the Mac version of Aunsoft Final Mate for managing HD camcorder footages. I just downloaded its free trial version and it offers a simple way of garping footages directly from camcorder. And also it provides a attractive feature to join flawlessly and split accurately native MTS files for video file output with original MTS format.
Maybe this is the tool cwhich an help you out, angelanna.
Enjoy your video.

How To Install Multiple OBIEE Instances On One Linux Machine

Hi,

Hi
I was not much clear about what you are telling
See my first OBIEE instance URL is http://hostname18.oracle.com:7777/analytics (As i deployed OBIEE on Application server 10g(OAS1))
and second one is http://hostname18.oracle.com:7778/analytics (As i deployed OBIEE on another Application server 10g(OAS2))
Also My port for first OBIEE instance is 9704 and second one is 9725(Which i changed to this)
Now tell me what are all i should update

How to keep multiple function modules under one Web service

Hi Experts,
I have Three RFC function modules and i need to create one web service for these three RFC function modules. I know How to crearte a web service for one function module.
please suggest me How to keep multiple function modules under one Web service.
Thanks in advance
Lakshminarayana

Hi Lakshmi,
The best way to do it is to assign all the three RFC Enabled FM's to one function group. Later on the top menu in Utilities you get an option to Create a Webservice from a Function Group.
You can create one single Webservice using all the the 3 FM's.
I hope this helps.

How to setup multiple base station under one network?

How to setup multiple base station under one network? I have 6 rooms but one airport base station makes really difficult to get good signal from every rooms. I wonder if I can setup multiple airport base stations talking to each other under the same network to build up the signal strength will help solve this problem. But, is it possible? How?

One route would be to utilize a "roaming" network. In a roaming network, you would connect multiple AirPort Extreme Base Stations (AEBS) to the same Ethernet. Of course, this would require that your home is already wired for Ethernet.

How to combine multiple Unmanaged Solution to one single Managed solution

Hi,
How to combine multiple Unmanaged Solution to one single Managed solution.?
There were some other third party developer have kept things lik ein UAT there are 2 release solution and both are Managed Solution.
And in Production the changes are only deployed for release 1 and for the release 2 changes deployment needs to be done.
But when i import that second release Managed Solution from UAT to Production then i got number of elements missing but i have checked they are already there in Soolution.
I did some R&D on this but not much helpful.
I thought i require to convert Unmanaged Solution of Production environment to Managed first for first release and then needs to import Managed solution of UAT to Production for second release.
Is this the right way to overcome form this situation?
Any help and response would be really appreciated.
Thanks.

How to Save Multiple Records In Data Block

Hi All,
I Have Two Blocks --> Control Block,Database Block
Please Any Idea How to Save Multiple Records In Data Block when User changed Data in Control Block.
Thanks For Your Help
Sa

Now i have to use each record of control block(ctl_blk) as where condition in data base block(dat_blk)and display 10 records from database table.>
Do you want this coordination to be automatic/synchronized or only when the user clicks a button or something else to signal the coordination? Your answer here will dicate which trigger to put your code in.
As to the coordination part, as the user selects a record in the Control Block (CB), you will need to take the Key information and modify the Data Block's (DB) "DEFAULT_WHER E" block property. The logical place to put this code is the CB When-New-Record-Instance (WNRI) trigger. You code will look something like the following:
/* Sample WNRI trigger */
/* This sample assumes you do not have a default value in the BLOCK WHER E property */
DECLARE
   v_tmp_dw    VARCHAR2(250);
BEGIN
   v_tmp_dw := ' DB_Key_Column1 = '||:CONTROL.Key_Column1||' AND DB_Key_Column2 = '||:CONTROL.Key_Column_2;
   Set_Block_Property('DATA_BLOCK', DEFAULT_WHER E, v_tmp_df);
   /* If you want auto coordination to occur, do the following */
   Go_Block('DATA_BLOCK');
   Execute_Query;
   /* Now, return to the Control Block */
   Go_Block('CONTROL_BLOCK');
END;
The Control block items are assigned with values in Form level (Key_exeqry).If your CD is populated from a single table, it would be better to create a Master - Detail relationship (as Abdetu) describes.
Hope this helps,

How to save 2-3 doc in one folder on ipad

How to save 2-3 doc in one folder on ipad.

Got it figured out ... but I'll repeat it here in case it helps others.
When I went to "Documents" it was always bringing me into a subfolder within (probably where I'd last been). And I think I had so many files in Documents from trying over and over that if I ever did end up there, I wasn't finding what I'd just opened because there were so many.
Thanks again for your help!
