Comparison of suspicious of all references
I have my mistake using Find bugs tool, get suspicious the next integer references comparison, you can you please inform me how to solve this problem?public boolean equals (Object o) {}
If (o == null) {}
Returns false;
}
return (this.orderNbr == (((ProductCategoryType) o) .orderNbr));
}

Yes, people should compare the fields of integer type by using the equals() method.
I think that code reusable standard would look like
public boolean equals(Object o) {
if (o==null) return false;
if (!(o instanceof ProductCategoryType)) return false;
ProductCategoryType that = (ProductCategoryType)o;
if ( (this.orderNbr==null) && (that.orderNbr==null) ) return true; // yes ?
if (this.orderNbr==that.orderNbr) return true;
if (this.orderNbr==null) return false;
return this.orderNbr.equals(that.orderNbr);
}

If any software is uninstalled, the registry contains all references to this program?
Original title: registry - Windows 7 and 8
This is a generic issue, not a specific problem.
If I uninstall a program using the control panel (the uninstall has been total, which means that no parts of the show were asked to hold), the registry should contain all references to this program?
If the answer is YES, why?
Bill S
The answer is none, but some programs leave stuff behind. The uninstall program has a list of things to delete, and sometimes the developers who build the program do not remember to list everything in the Uninstall list.
It is a big reason for the new model "app" of Windows 8: stand-alone applications that can be neatly installed, managed, and removed. More like how Apple and Linux.

Is there a good way to find all references to a table or a column?
I have recently inherited an application large apex and receive requests to make changes. I would like to ensure that any changes that I could do on a table or a column in a table affect application pages which I think are involved. However, demand is high, and I'm assuming that it is possible for other pages may refer to the same column or table, and I was not aware of these references (at least until after he breaks once I have change the column or table).
My question is this: is there an integrated report, or a way to query apex, who will tell me ALL references to an application to a particular table or column? This way I could fix all pages in the application, rather than waiting to break.
Thank you!
John
John,
Look to the upper right while in the Application Builder, for the area of the search Application . Enter any string you want and APEX will search to find and view a report that contains a link. Click the link and APEX will show the page and control chain concerned.
Here's another way; query the table APEX seen through this code:
SELECT workspace, workspace_display_name, application_id, application_name, page_id, page_name, region, item_name, display_as, display_sequence, item_label, db_column_name, db_table_name, help_text, item_id FROM apex_application_page_db_items WHERE workspace = :workspace AND db_table_name = :table_name AND db_column_name = :column_name

I modified reference.vi get all the controls (http://zone.ni.com/devzone/cda/epd/p/id/2902) and it works very well in LV8.6.1. With LV2009, I get the class conflicts of wire (for references).
With LV8.6.1
With LV2009
I tried to type cast (more generic class) but it doesn't work, someone has an idea to solve the problem?
Jean-Marc
I agree with you,
I made the changes as soon as this morning. I just need the reference of the tab control itself (I don't need references from pages). I used 'generic' instead of 'control' and I catalogued to a more specific class (control) in step 5 in the block diagram.
Thank youJean-Marc

LV Scripting how to get all references to schema object.
Hello
I'm trying to find a way to get a list of all the schema for a VI object given. I tried the 'Plan - [AllObjects]' method, but this function returns references to key objects in the diagram, not all the objects recursively, which are inside these main objects. Is there a method to do? If not, is there a way to do it recursively? I did not found anything so far.
Thank you
Michel
Check the attached file.
Published:
In addition, it would be possible to make this operation recursively in the sub a high level VI VI?
Oops I missed the recursive part, you will still be able to use the code in the attached VI, however, you must provide the references VI/Subvi of recursively.

Remove all references to IE8, IE9.
I use IE11 on Windows 7 Ultimate 64 bit.
There are many references to registry to IE8 and IE9 in the HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main registry location. I want to remove these references REG_BINARY and REG_DWORD, but also the REG_BINARY WINDOW_PLACEMENT because IE11, no matter what I do, not, among other things, desktop shortcuts or full open or enlarged. I backed up the registry. I tried all the answers provided by the community, Google, Bing and a host of other search sites. IE11 also lock up, run very fast or drag his butt.
Continuing along this question, in c:/Windows/winsxs there are dozens of files in which properties/details clearly version 8.* * and 9.* * which I believe must be eliminated as well. I think my pc is confused about things compared to Internet Explorer.
I also scanned infinitum for horses of Trojan, virus, malware, etc. with Norton Security, Malwarebytes Pro, TrendMicro Housecall, Odile, Norton Power Eraser, SuperAnti Spyware and other known virus scanners, many of them have been recommended by Microsoft itself. I use not any what registry cleaners, fixers or doctors of any kind ever.
So, please, all moderators and people at Microsoft, please weigh in on the work of the registry, I mentioned, and the winsxs works also. Or y at - it a setting that I forgot.
I did 20 questions with a couple of moderators already so any help will be very appreciated.
Thank you in advance!

Hi Chris,
Important: Serious problems can occur if you modify the registry incorrectly. Therefore, you must make sure that you follow the steps carefully. For extra protection, you can always back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base: How do I back up and restore the registry in Windows
Your question would be better suited for the IT Pro TechNet public. I ask so post you your question in the TechNet Forums.
Do not hesitate to write to us in case you have any problems/concerns while working on your computer, we will be happy to help you.

Can I safely remove all references to the CHROME of about: config?
I was told that once I installed and used CHROME, it took longer for the most part, the operation of any other browser. I removed CHROME better I could, for reasons of confidentiality, but I noticed in FIREFOX about: config many references to CHROME. I want to delete them. What is recommended or safe? Or would I be better to uninstall FIREFOX and download a new copy of it? ... and if so, how can I save my favorites, etc. ??
Best regards
Bill LindquistHello Bill, none of the entries in firefox/a words of: config that contain the term 'chrome' is related to the browser google chrome.
chrome is a general term used to refer to the user interface of the browser (in contrast to the content - which is usually the information provided by Web sites). This reference is present in firefox long before the competing product with the same name came on the market.

all references to change the positioning of...
Hello
Are there references that you know maybe as to how I can replace the controls for the next and previous arrow in the Lightbox image gallery?
The default value is that they are on top of the image itself. I want to move them outside.
Also - is it a single known fix do the slide images aside rather than fade in? -J' had many prefer rather than interaction.
Thank you.
It worked! Don't you think that it is an acceptable method to solve the problem?
{a.lb - lb - nav-prev
Width: 34%;
position: absolute;
left:-80px;
Background: url (.. / img/lightbox-img/prev.png) left 48% no-repeat;
filter: progid:DXImageTransform.Microsoft.Alpha (Opacity = 0);
opacity: 0;

Find all references file/URL
This seems like a simple question for a person. I have a project that I upgraded. He uses many areas of click that uses an action = open a Url or file and then calls a PDF file.
My question is there a Captivate feature that will show me all files that are called within the project?
You can try to look at the dialog box Interaction advanced under project > Advanced Interaction.
This shows all the interactive objects in the project and what are their actions on the success or the last attempt.
You would look for those who say open a URL or file.

Comparison of references has failed
Hello
recently, I observed a strange behavior when you try to compare two references referring to the same controls typedefed.
What I want to achieve:
I created a control typedefed (a group of radio buttons with additional information) for use on the front end of the user interface. To manipulate the content, I created a Subvi, which takes a front control reference. The feature is not interest - he controls the values represented by radio buttons, so it is a sort of "advanced radio button control.
Now, I need to address the data structure, the cluster components. The first approach was to compare the labels with a hard-coded string. But then I ignored this first attempt because if someone changes the labels of front-end control the Subvi is no longer visible reason. So I decided to compare the references.
So far the story of presentation...
Now, I have observed some kind of pathological behavior - and this is my question:
Attached to this post is a little demonstration VI which should clearly state the question.
First of all, I created an instance of the control. For simplicity let's call him "MyControl".
Then, I created two references to this object.The first by selecting the Reference of the Server 'VI' in the 'Application' menu. Done, right click on the reference and choosing the menu option 'Link to .../Pane/MyControl' creates the link to the control. If I open the same menu entry, there is no point of control in the menu (this becomes important later).
The second, that I did a right click on MyControl and selecting the menu item "Create/Reference". As for the first difference this reference shows check marks in the entrance 'Link to... ". " of the right click menu.
Both references seem to be related correctly to control if used to read or write all properties. But if I try to compare using the "Equal?" 'Différent?' or the 'Comparison' palette, result is inequality. Unless we compare the cast type numbers or references by itself.
I know that the value of references may differ in value, but the comparison functions that must manage in resolving references before equality checking. (refer to the documentation for the range of comparison)
Why the references are uneven? Also, right-clicking on the control or its terminal and by selecting "Find all references" in the menu right click - only considers the first of these two references.
Is this a problem of referencing the typedef and contains the structure the typedef? (only typedefed controls behave as described, after that disconnection of the typedef comparison works)
One last thing, I found out: select 'Link to .../Pane/MyControl' in the menu on the right - click with the button of the second reference (the checked input) connects the reference correctly, even for the comparison functions and function "Find all references" . As a result, the checkmarks disappear.
How can I ensure a good related references? Is there a better way - more stable - to refer to a control by a label or a reference?
Is this a bug? I'm using LabView 2011 (without SP1) on a computer laptop win7.
