How to detect USB Flash Drive name in LabVIEW

Hi there
I was looking for how to detect a USB Flash Drive name in Labview
appearently every time i insert USB Flash Drive in a computer, windows assign it a different name
once "J:" and sometimes "M:"
Is there anyway to obtain USB Flash Drive name programmatically in Labview ?
Because in my program an user shouldn't be able to access HDD Drives except his USB Flash Drive (for inserting some file ...)
thank you and excuse me for my poor english

I was able to get the demo.vi to load, but it could not load the other two because there is no block diagram associated with those. I'm not sure why this is. I haven't had any issues with other llbs before.

How to detect a selected row in ALV GRID

Hi,
Can anyone tell me how to detect and catch an event when a row is selected in an ALV GRID?
I would like to catch such event when the end user presses Ctrl + Shif + Space bar.
Thank you and best regards.
Hassane.

Hi,
Use this wiki link, to have a checkbox with all the records in ALV Grid and to process those selected records at a user command, as per the requirement.

How to detect the Acrobat Browser Plug-in version installed on a users system for non-IE browsers?

How to detect the *Acrobat Browser Plug-in version* installed on a users system, on Firefox, Safari, Opera, etc?
Or one script for detecting Plug-in version for major browsers. Need full example code.

Wrote an article on this with code samples (Javascript + HTML) - basically there are differences between IE and other browsers. Chrome natively comes with the Chrome PDF Viewer so I've incorporated that in my detection script.
The script detects the browser type, and the installed acrobat version...
Have a look here:

How to detect the path of Temp directory

I am writing a class library which allows users to manipulate a database in the web server java applications/applets. In my logic the Application/Applet communicate with a CGI script/Servlet in the server and that do all the database handling. My objective is to make the Client independant from the Database Drivers, and to some restrictions and possible security threats that can arrice when accessing the database directly.
99% of the work is done and now I am doing the fine tuning.
My Problem:
When the user downloading a blob object from the server database. each time the program read the blob it will get a new copy from the server. This is not good if the blob is large (few 100 megs) . So I am going to implement a cache system. but the problem is If I am caching in the memory it will not support large objects (Memory is a limited factor). So the preferance is use the Temperary files but I do not know how to detect the path to temperary folder.
And my 2nd questions is are the applets allowed to write and read in temperary folder.

The Java default temporary file path can be determined with
System.getProperty("java.io.tmpdir")This is typically the same value as the os environment variable

How to detect color pages in a PDF?

I am using a C++ Acrobat plug-in do read/edit a PDF file.
I need to get the total number of pages in the PDF as well as the page numbers of color pages.
So far I have been able to get the total number of pages using PDDocGetNumPages() without any trouble.
However, I cant seem to find an API that lets me know whether a particular page is color or not. Is there a way to do this?
Thanks in advance!

But what if there is RGB data that means black or gray (R == G == B), does that mean black or RGB?
There is some sample code in the SDK for iterating over the content in the PDF, and then you can get the colorspace and the color of each object.
But you really need to do some background research on colors & colorspaces to properly achieve this goal.

How to detect the HTML extension window close in In-design? Does the In-design throws any event on opening/closing of extensions?

How to detect the HTML extension window close in In-design? Does the In-design throws any event on opening/closing of extensions?
I have a HTML extension running in In-design CC 2014 version.
I want to perform some required set of actions before my extension window is closed(by clicking on the cross button on top right corner).
Does In-design throws any event for it? Or can we capture it using C++ plugin in some way?

Naah.......haven't got any event for that yet.
Although, since HTML extensions are using chromium browser, as a workaround, u can attach listener to HTML onClose event, but it won't solve any purpose if you
are looking to logout session or do some business login in your code.

How to detect the final loop iteration of a step in a PostStep Engine Callback?

I see the need to use a PostStep Engine Callback and look at the Step.Result container of the caller.
My issue: If the caller is configured to loop, the PostStep Engine CB executes with each iteration and I do not see how to detect the final iteration (which is the only iteration I am interested in).
Ideas are welcome. Thanks in advance,
Guenter

Guenter,
well, the way i discripted IS the generic way. The reason for this is the following:
You can compare TestStand very well with procedural programming languages. So you have variables with different lifetimes and scope. RunState is one variable, which is available in every scope, but it may have different content.
So you leaving the execution of your clientsequence in order to call the callback, you leave the scope of the RunState from your clientsequence. But only there the information is stored on how many iterations are left. It does not make sense to pass this anywhere, since the execution of your clientsequence has to decide if to loop further or not.
But, please note that there are different scopes for the "disable result recording" as well. You have found the most global one, the station option. But you can as well set this in the sequence settings (Edit >> Sequence Properties >> Disable Result Recording for All Steps) and at step-level (Run Options >> Record Result {uncheck it}).
Looping on a single step using the step settings, you can additionally choose not to record results for each iteration. This will lead to only a single entry in the ResultList, the overall result of the looped step (if resultcollection is enabled of course!).
hope this helps,
Norbert

ANSWER: HOW TO DETECT Java Plugin from JavaScript

I created a new topic because the questions about
how to detect Java Plugin in browsers are scattered
thoughout this forum.
Basically you need to employ two approaches for IE and NS.
In IE you need to try to instantiate a small applet
(not your production applet) in order to see if browser
can do it. if the browser can do it, you can make a
call applet from JavaScript in order to find version of
JRE (as well as a host of other things).
In NS you can write a simple JavaScript which will
interrogate the browser for all plugins installed. Then
ypu can make a desicion whether to pass execution to
the next(or generated) page which hosts your applet,
or ask the user to download/install a plugin.
I ecourage everybody to host a plugin on your site
rather leave default link to it which is generated by
html converter.
In order to run sample,
Prerequisites:
Java Plugin 1.3.
If you have a different version of plugin,
substitute hardcoded plugin version in JavaScript for
value that you have.
1. compile java file
2. put class file in the same directory with html file
3. load html file into the browser.
4. press "Check Java Plugin.." button
5. see it work
6. examine code
7. uninstall plugin
8. repeat steps 1 - 4
9. see it work
10. install plugin.
Sample code follows:
**********************HTML FILE BEGIN***********
<HTML>

How to detect the OS version and the hardware info??

Hi all, according to the project needs, I to know how to detect OS version and the hardware info.
The point is to detect client's OS version, weather Win98, 2000, XP, Vista.
I have been search the information for several days already.
But can not really found a example which returns the OS version like"Windows XP Version 2002 *****".
And also could not find the CPU type such as"Core 2 due, or pentium D".
Is there anyone have done this before?
Thanks.
The Info I need looks like the photo below.
Message Edited by EricLu on 07-21-2009 08:09 PM

Well, in fact I have the VI and also read the topics as well...... The searching tag is OS info , system info......... After reading your post, now I understand the relation between the version number and the real OS version now, tks. And another problem is, the processor type returned within the VI have only 4 type:"INTEL 386, INTEL 486, PENTIUM, Unknown".
It can not really return my CPU TYPE. For example the desktop I’m using now is a Pentium, D , 2.80G, 2.80G.. and it only returns type "Pentium". That's why I'm asking is there any other way to do this...... (( Please forgive me if you can not really know what I'm talking about in my first post, now I know how bad my english is....... )) I guess I can only try to find out the solution from the registry then... Thanks for your information and reply.

How to detect session objects in a project

Hi,
There are many session objects in our project which has over 1000 classes. What would you suggest as the best practice to identify all of them. I am using eclipse. How to detect they are serialized or not. If not serialized how could i make sure they are serializable or not.?
Appreciate your time.
Pralav

If not serialized how could i make sure they are serializable or not.?By implementing the Serializable interface.
If you want to ensure they can't be serialised, then you implement Externalisable and throw exceptions when you override readExternal() and writeExternal()
As for identifying the objects that are added to a session.... do a search for things like session.setAttribute() on your code. No easy way.
regards,
Owen

How to detect modifications in an ABAP Object?

Hi all,
I was wondering if there's a simple way of detecting modifications in an ABAP Object.
Imagine an ABAP entity object which holds several attributes and you need to know if this object has been modified. Instead of having to check attribute by attribute to compare it's previous value with the new one I came with the idea of calculating a HASH code for the object before the execution of the application which can change the object attributes and comparing it with the HASH calculated for the same object after the execution.
That way, checking only two hashes simplifies a lot the code. So.... is there any way of calculating a HASH for any object instance? if not... any other approach?
Thanks in advance.

Sorry Hüseyin Dereli, but I'm not talking about source version control, but how to detect attribute modifications of an ABAP Object Instance.
for example, suppose you have a program which reads data from DataBase and stores temporally that data into an ABAP Object like this:
ABAP Object AAAA{
   private attr1
   private attr2
and passes this ABAP Object into a screen for user interaction, or even a FunctionModule or Method or anything else...
data: myObject type ref to AAAA.
myObject-attr1 = 1
myObject-attr2 = 2.
CallFunction AnyFunction Changing data = myObject
After the execution of AnyFunction I would like to know if myObject has been changed but I'm trying not to check attribute by attribute because if myObject has a lot of attributes (not in this example but in the real source code)
It would be great if we could do something like this:
data: myObject type ref to AAAA,
          oldHash type hash,
           newHash type hash.
myObject-attr1 = 1
myObject-attr2 = 2.
oldHash = myObject->get_hash()
CallFunction AnyFunction Changing data = myObject
newHash = myObject->get_hash()
if oldHash NE newHash.
* MyObject has been modified
endif.
