I'm looking for code to measure SNR, SNDR, etc. using Measurement Studio, Visual Basic.

I've collected audio ADC data and wish to measure signal-to-noise, frequency, amplitude, etc. I'm using Measurement Studio with VB.

Frequency and Amplitude should be easy to measure. The CWDSP frequency domain processing methods perform transformations between the time domain and frequency domain and perform analysis in the frequency domain. Slightly more difficult is the measurement of SNR. I would recommend the following tutorial:
"The Fundamentals of FFT-Based Signal Analysis and Measurement in LabVIEW and LabWindows" available here. This page also links to a LabVIEW example, which can be used to understand the dataflow and functions necessary to create the system.
There is also a good signal to noise ratio tutorial here.

How to look for a certain value in a database using sql

Hello everyone. How do you do this in SQL? Or, is there a way to look for a certain value in a database? What I'm trying to do is this:
I want to look for the exact value "abcdefg" in the database so that oracle will return me details on the following that contains the said value:
1. the name of the table(s)
2. the column/field name(s)
Note: "abcdefg" could exist in different tables with different column names with different data types.
Any help is much appreciated. Thanks.
UPDATE: What about if I just want to check those fields/columns with string data types?

HI i have tried so many times to import images, both pictures and video from my hard drive to elements 131, and it keeps coming up with the error message " .....has stopped working we are looking for a solution to this problem etc " please help!

After taking days to upload elements 13 I am now having trouble even trying to import my images and videos into the program for editing. Each time I IMPORT files an error message comes up that says " ....has stopped working, we are looking for a solution to the problem and will notify you if a solution is found" I have not been able to edit ANYTHING or even drag files/images to the time line.... is it me? is my computer too slow? surely if it was, then Adobe elements 13 would not have installed in the first place? please someone help me sort this out as I have a deadline to make for a docco! thanks in advance Lyddy

From the Premiere Elements Information FAQ http://forums.adobe.com/thread/1042180
•You MUST use an account with Administrator Privileges to run Premiere Elements
•(Doing Run as Administrator http://forums.adobe.com/thread/969395 [says Encore and also for "All" versions of Premiere] will sometimes fix "odd" errors)
•What version of Premiere Elements? Include the minor version number (e.g., Premiere Elements 12 with the 12.1 update)
•What operating system? This should include specific minor version numbers, like "Mac OSX v10.9.4"---not just "Mac"
•Has this ever worked before? If so, do you recall any changes you made to Premiere Elements, such as adding Plug-ins, brushes, etc.? Did you make any changes to your system, such as updating hardware, printers or drivers; or installing/uninstalling any programs?
•Have you installed any recent program or OS updates? (If not, you should. They fix a lot of problems.)
•What kind(s) of image file(s)? When talking about camera raw files, include the model of camera.
•If you are getting error message(s), what is the full text of the error message(s)?
•What were you doing when the problem occurred?
•What other software are you running?
•Tell us about your computer hardware. How much RAM is installed? How much free space is on your system (C:) drive?
•How many and what speed are your hard drive(s)... ie 5400rpm or 7200rpm or?

•What is your exact brand/model graphics adapter (ATI or nVidia or ???)
•What is your exact graphics adapter driver version?

Looking for an example from app gallery that uses WAAD for identity

I'm looking for an example from the app gallery (http://azure.microsoft.com/en-us/gallery/active-directory/) that uses WAAD for identity. I need one the show our business what the process would look like for an organization signing up for a SaaS offering
via the App Gallery. I know all the Microsoft applications use WAAD but I was hoping to find a third-party example. What I mean is an app where all tenant and user identity is done using WAAD as opposed to federated identity.

I doubt that what you are looking for exists yet.

Looking for pictures of Apeture Books to be used as samples

Anyone know where I can find pictures of what the end result of an Aperture Book looks like so I can show it to a Client?
If I show the Client the book in Aperture, it is difficult for them to visualise what the final book will look like.
Any help here???
Thanks!

Thanks for the link. I did know about this facility to preview the book before buying already. What I'm looking for is some kind of picture of what the final book actually looks like, something I can show a Client and say "it will look like this".
Do you know of anywhere I can see a jpeg or some equivalent of the final results?
A deep Google search has revealed nothing...
Thanks,
Chris

How can i measure the transmision time in gpib with visual basic with more precision if i use time() function?

I want to take a measurement of the time that i use to make a gpib transmision in a Visual Basic program,i use the function TIME() to take the time in the begining and other time in the end,but this way only give me precision of seconds, and i want miliseconds,can i use other function,other way?
Can answer in spanish?

Try using GetTickCount() API function, which provides millisecond precision. If you need more precise timer, try using QueryPerformanceCounter() function.

RMAN script for hot backup (looking for code critic) code attached.

Hello Guru's,
I have been having soem trouble running a successful hot full rman backup nightly.
We max our CPU load whenever our RMAN takes too long and conflicts with a Legato tape backup. I have a development server that I attempted to get a consistent backup time duration that is rock solid as to not conflict with the Legato backup time.
I just found out about duration with RMAN scripts here is my code:
#!/bin/bash
#rman backup script for daily hot whole database backup
at -f /hd1/rman_scripts/rman_backup 0600 tomorrow
rman target/
run {
allocate channel d1 device type disk format '/path/%U';
backup duration 1:00 partial minimize load database filesperset 1;
backup as BACKUPSET tag '%TAG' database;
backup as BACKUPSET tag '%TAG' archivelog all delete all input;
delete noprompt obsolete;
release channel d1;
exit
It completes the backup, but does not use the 1 hour allocated- it only uses 15 minutes on average and creates many files instead of normally three backup files.
Here is the results from querying the v$rman_status table for operation,status,start_time:
RMAN,FAILED, 17-OCT-06 0600
BACKUP,FAILED,17-OCT-06 0600
RMAN,FAILED,17-OCT-06 0606
BACKUP,COMPLETED,17-OCT-06 0606
BACKUP,COMPLETED,17-OCT-06 0606
BACKUP,FAILED,17-OCT-06 0615
RMAN,COMPLETED,17-OCT-06 1513
REPORT,COMPLETED,17-OCT-06 1513
DELETE,COMPLETED,17-OCT-06 1513
However, the timestamps of the backupset files it creates is:
06:15 and not 1513?????????????
RMAN appears to have only taken 15 minutes to create the files, why do I have a completed timestamp from v$rman_status of 1513???
Please advise and comment, I am just learning RMAN.

Try to remove the DURATION option in your script.
Here more details about that part.

Hello,
Use below code lines to write ur code:
This is in case of transformation, do it in end routine:
data: wa_result_package like line of result_package,
it_DSO2 type standard table of /BIC/A<DSONAME>00,
wa_DSO2 like line of wa_DSO2.
select * from /BIC/A<DSONAME>00 into corresponding fields of table it_DSO2
for all entries in RESULT_PACKAGE where FSRNO = result_package-FSRNO.
loop at RESULT_PACKAGE into wa_RESULT_PACKAGE.
read table it_DSO2 into wa_DSO2 with key FSRNO = wa_RESULT_PACKAGE-FSRNO.
if sy-subrc = 0.
wa_RESULT_PACKAGE-FSRNO = it_DSO2-FSRNO.
modify RESULT_PACKAGE from wa_RESULT_PACKAGE.
endif.
endloop.
Use proper object names. I have just used referenced sample.
