How to do a loop for controls

I have the same code to be run for all the ring controls.How to do this.I want to put the code inside the loop but only the controls name is to be repeated or changed.thanks in advance

In the file attatched I included the things I thought you could do. Since all the Rings are the same you can put them in an array. The operation you are doing is allways the same so I put it in an SubVi. Now you can easily use a loop to calculate the 8 differences you are looking for.
Hope this helps

How to download apple loops for Garageband 10.0.1 ?

How to download apple loops for Garageband 10.0.1 ?

If iDVD was not preinstalled on your Mac you'll have to obtain it by purchasing a copy of the iLife 09 disk from a 3rd party retailier like Amazon.com: ilife 09: Software or eBay.com. Why, because iDVD (and iWeb) was discontinued by Apple over a year ago.
Why iLife 09 instead of 11?
If you have to purchase an iLife disc in order to obtain the iDVD application remember that the iLife 11 disc only provides themes from iDVD 5-7. The Software Update no longer installs the earlier themes when starting from the iLIfe 11 disk nor do any of the iDVD 7 updaters available from the Apple Downloads website contain them.
Currently the only sure fire way to get all themes is to start with the iLife 09 disc:
This shows the iDVD contents in the iLife 09 disc via Pacifist:
You then can upgrade from iDVD 7.0.3 to iDVD 7.1.2 via the updaters at the Apple Downloads webpage.
Export the slideshow out of iPhoto as a QT movie file via the Export button in the lower toolbar. Select Size = Medium or Large.
Open iDVD, select a theme and drag the exported QT movie file into the open iDVD window being careful to avoid any drop zones.
Follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
And yes, iDVD 7.1.2 will work with Mavericks.
Happy New Year

How to use a loop for a object

Hi, All
I have a procedure that needs a collection to pass in. The pass_in collection has multiple records with multiple fields, so I guess I need a loop for each record.
How to assign each record of multiple fields to each corresponding local variables?
Thanks In advance
T_Object is a table object
T_ProfileInfo is a collection
procedure P_Updateprofile(UserId in number, NewProfileInfo in T_ProfileInfo) as
V_B_ID number;
V_A_ID number;
V_Profile      T_ProfileInfo;
begin
     V_Profile := NewProfileInfo;
     --use the loop for each records
FORALL i IN V_Profile.FIRST..V_Profile.LAST
-- assign each value to the local variables
-- I got error here. ideally I want to assign each record to the local variables
     select B_ID, A_ID
     into V_B_ID, V_A_ID
     from table(V_Profile(i));
     -- insert the record into the table
     INSERT INTO PROFILE
     VALUES (UserId, V_B_ID, V_A_ID);
     commit;
end;

You don't say which version of the database you are using. Oracle extended the collections functionality in 9.2....

How to execute a loop for a user specified amount of time

This seems like it should be a no brainer. But I can't figure it out. What's the best way to execute a loop for a user specified number of seconds?

You can use the Elapsed Time Express VI (available in LabVIEW 7.0 and later). I have attached a sample VI saved in LabVIEW 7.1 format that shows how to use this Express VI.
Good luck,

How to stop while loop for particular time

               test(); // call thread function
               i++;
in this code while loop don't stop
plz help me to stop while loop for certain period by using thread or other technique

Yes.. the original problem would be your test() method put the sleep in an entirely separate thread of execution. So the thread is created then the method just keeps waiting. The while loop should directly call Thread.sleep... which you have apparently figured out!

How to run a loop for 1hour

Hello All,
I am very new to labview and its components. I want to program a loop which would run for one hour.
Actually, I would like to make it more user friendly, by asking the operator to enter how long he would like to run the code.
Can anyone please suggest me how to do this?
Please excuse me if I entered into wrong forum ...
Now on LabVIEW 10.0 on Win7

How to create a loop for my problem? Please read for more detail.

Hi guys,
I am doing my project and currently i faced one problem and that is more towards looping i guess. My project is about embedding and I had done all the embeding stuffs already but I am only able to embed my barcode into image at starting at coordinate 0,0.
What i want to know is how do i had to structure my loop so that i can embed my barcode even when i start at x=20 and y=30 for example?
currently i used nested for loop which is why i can only start at 0,0.
I wanted to make it something like this:
for<lets make it x=20>
for<lets make it y=30>
<my code retrieve pixel at x=20 y=30>
<my code retrieve pixel of barcode at x=0 y=1>
end
end
end
I wanted to have something like above where i can start at 20,30 but at that certain cooridnate i will starting retrieve barcode pixel at 0,0.

So just say what you don't know how to do, because what I showed is exactly what you need.
So please answer the following:
1.) I have an image of my barcode and I don't know how to paint it onto another image.
or is it
2.) I have a routine that draws a barcode at a fixed location and I don't know how to get it to draw anyplace I tell it.
or
3.) I don't have anything yet, and I want someone to code this for me.
or it is
4.) Les you don't have any idea what I want to do, so here is what I need (pay more attention):
but in any case (well except #3), you'll be better off if you can give us some code to look at and explain what you are specifically trying to do and where you are having problems.

How to make default value for controlling area for MDG-F 7.0

how do we default certain pre-defined values for few fields? e.g. controlling area or company code for MDG finance?
Thank you in advance.

Hello Sahil
Account and CC/PC are 2 different entity types. For PC and CC there is dependency. First you have to load Cost centers and then load PC.
For CC - load CC master data first. Then load hierarchy file then group file and finally assignment file.
Follow same process for PC.
GL you can load independently but you have first load group GL then operational GL and then GL at company code level,

How to use jampack loops for multiple accounts

I have one computer but there are two people that will be using it. I have the jampack loops and added them to my account...but when the other person logged into their account those loops weren't in their GB library...do we have to ad them into each accounts libraries for seperatly or is there a way to do it once for both??? (it would save more HD space, wouldn't it?)
thanks

OK I FEEL STUPID, before i did was i said i was going to, i look in the pref for GB and noticed under the loops tab, at the bottom there is a box to be able to choose user only or all users...so i took out the loops from the library folder and trashed them, the checked the box for all user and repulled the loops back into the GB loop browser as instructed, logged into the other users account and as if by magic, the jampack loops where there!!!
Thank you very much for trying to help me HangTime, i appreciate it!
I guess next time i'll look for the obvious.

How to create a loop with control over iteration?

Is it possible to create your own loop where you can CREATE your own iteration variable and change the iteration variable's count whenever its needed?
The For loop and While loop in labVIEW have the iteration (i) provided but I can't change where it begins and such. The i always starts at i=0, however, if i can make my OWN iteration variable, where I can feed back into it whenever I need to jump to a specific iteration count, it would be awesome.
Thank you.

How to put a loop for the entered value

hi all,
I have 6 different scenario or cases and in my selection screen i am entering a value say 10. then in my program, it should go to all the 6 cases along with the first 4 cases. so the total turn is 10.
if the value is 20, then it should go 3 times to all the 6 cases + first 2 cases.
how can i handle this. provide the coding if possible.
thanks in advance
points will be rewarded

Hi!
If i understand right, maybe you can do something like that:
data: v_mod type i,
      v_div type i.
Selection-screen...
P_input (type)
start-of-selection.
v_mod = p_input MOD 6.
v_div = p_input DIV 6.
*For my 6 scenario
Do v_div times.
*     do 6 things....
enddo.
*For my first cases.
do v_mod times.
*     do my first case things
enddo.
I hope it helps,
Regards,
John

Can we cascade PID and PIV loops to control the servo motor

hi
presently we are using PID loop for controlling the motion of a servo motor using ni-7352 card. We are not able to receive the desired response from this implemenatation. So is there any other alternative like using a PIV loop or using PID cascaded with PIV to achieve a better response. If there is possibility help us to proceed further with this.
also tell us which is more reliable 1)using PID alone 2) Using PIV Alone 3) using PIV and PID cascaded.
please mail to this query to [email protected]

Sidda,
before you start thinking about advanced control architectures I want to ask you to tell me some details about your system behavior and the control parameters that you have used. I have used 73xx boards for very dynamical systems and I have always been able to find control parameters that resulted in a very fast and stable system behavior.
For the case that you need some help with tuning please have a look at this link. In many cases autotuning doesn't result in good system behavior but you will find a lot of interesting hints about the manual tuning process there (e. g. that increasing the Kd gain typically results in a better damped system).
If this doesn't help please attach some screenshots from your step response and the control parameters that you have used.
Best regards,

How can I repeat a for loop, once it's terms has been fulfilled???

Well.. I've posted 2 different exceptions about this game today, but I managed to fix them all by myself, but now I'm facing another problem, which is NOT an error, but just a regular question.. HOW CAN I REPEAT A FOR LOOP ONCE IT HAS FULFILLED IT'S TERMS OF RUNNING?!
I've been trying many different things, AND, the 'continue' statement too, and I honestly think that what it takes IS a continue statement, BUT I don't know how to use it so that it does what I want it too.. -.-'
Anyway.. Enought chit-chat. I have a nice functional game running that maximum allows 3 apples in the air in the same time.. But now my question is: How can I make it create 3 more appels once the 3 first onces has either been catched or fallen out the screen..?
Here's my COMPLETE sourcecode, so if you know just a little bit of Java you should be able to figure it out, and hopefully you'll be able to tell me what to do now, to make it repeat my for loop:
