Is there a way to add multiple borders to a single cell with one click or do I have to add one border at a time for example, one cell with borders on three sides?

I would like to know if there is a way to add multiple borders to a single cell or selection of cells in one click. At this time, if i want to add for example a top border and a bottom border to a single cell I have to do this in two steps: first select the top border, style, thickness, and color, and then next select the bottom border, style, thickness, and color. Is there a way to select the top and bottom border of a cell in one click? Clicking on the top border then holding down the command key while selecting the bottom border does not work, nor does holding down the option key, the control key, or the shift key work. Thanks for your help.

Thank you for the suggestion but this did not work for my Mac. When a cell is selected for which I want borders, the entire cell is lit up. Then when I go to the border tool and select style, thickness, and color, the entire lit up cell takes on the border, that is the Outside Edges of the cell now have a border. So selecting the style, thickness, and color first doesn't work.
If I select the top border first (or any border), the drop down goes away and I can't select multiple borders - I get to choose one at a time. After selecting one border, style, thickness, and color, said border is now on the spreadsheet. Then I go back to the border selection and pick another border and the the previously selected style, thickness, and color reverts to null, so I start over with the new border style, thickness, and color. Yes, it is tedious.
The Fix would allow the user to select multiple borders, say left and right, before the drop down goes away after selecting only one border
Does it have something to do with Allow or Disallow border selection?

How do i get music videos to play like the music does on my ipad, for example one right after another and shuffle

I need to know how I can get the music videos on my IPad to play like the music does. What I mean id setting up a playlist, shuffle, and have them play one right after another instead of going back to the main screen.

At the top of the playlist where it shows the playlist title and the number of songs, there are two icons. Click the "play" triangle to add the entire playlist to "Up Next", or the "shuffle" symbol to do the same thing but in random order. But the currently playing track will stop playing, and all the songs in "Up Next" will be removed (replaced by the ones from this playlist).
If you hold down the "option" key while clicking those icons, the currently playing song will continue playing, and the new playlist will be added to "Up Next" (above the songs that were already there).

HT1311 Can I have two ITunes accounts at once. For example one for Canada and the other for France?

Would someone be able to tell me if I can maintain two I tunes accounts at once. We like to downloads movies from the French Itunes movie site but would also like to keep at the same time our Canadian account. I'm not to keen on having to cancel one account in order to access another.

Welcome to the Apple Community.
You can't keep changing accounts in iTunes, you will need to wait 90 days after changing once. You would need to use two computers or use two user accounts.

How to compare two strings whether both are equal while ignoring the difference in special characters (example: & vs & and many others)?

I attempted to compare two strings whether they are equal or not. They should return true if both are equal.
One string is based on Taxonomy's Term (i.e. Term.Name) whereas other string is based on String object.
The problem is that both strings which seem equal return false instead of true. Both string values have different special characters though their special characters are ＆ and &
Snapshot of different design & same symbols:
Is it due to different culture or language?
How to compare two strings whether both are equal while ignoring the difference in special characters (＆ vs &)?

Hi Jerioon,
If you have a list of possible ambiguous characters the job is going to be easy and if (＆ vs &) are the only charracters in concern awesome.
You can use the below solution.
Before comparing pass the variables through a replace function to standarize the char set.
$Var = Replace($Var,"＆","&")
This is going to make sure you don't end up with ambiguous characters failing the comparison and all the char are "&" in this case.
Similar technique is used to ignore Character Cases 'a' vs. 'A'

A timout generally means you are being ignored, or far more likely there's nothing that can respond despite the fact there should be.

SSAS - Many to Many Relationship Grain Filters Out Data (Many to One)

I have a simple Many to One example: One Fact Table record has many Dimensional Items. The Example I'm using is One FactEvent record can have multiple EventMembers. These members are always unique so the relationship is really many to one (vs.
many to many). The grain of the Fact is one row for every event. Not all events have members, but I have stubbed those with -1
I tried using a Referenced dimensional relationship, but it threw my total counts off. I decided to make it more complicated by using a
Many to Many relationship, but I had issues once I started slicing the data.
The following are my two very simple tables:
FactEvents:
EventMemberID MemberKey EventMemberKey MemberName MemberGender
1             1         -1             None       N
2             2         E2             Tyler      M
3             3         E2             John       M
4             4         E2             Sue        F
5             5         E5             Tim        M
6             6         E5             Jane       F
7             7         E12            Ashley     F
8             8         E12            Jessica    F
9             9         E12            Kristy     F
10            10        E17            Mike       M
11            11        E17            Josh       M

You can see many events have no members and some events have multiple members. There is not separate members Dim, just the bridge table. I tried to build view that would work as bridge tables, but it started to feel like overkill.
Here is the SSAS structure:
Cube:
I tried creating a bridge Dim and Measure Group that can be used to join FactEvents with DimMemberEvent:
When I query the database tables directly, I can get the structure I'm looking for:
Gender Count
F            5
M           7
N           15
This represents that although there are 20 events, there were 5 Female and 7 Male participants and 15 events with No participants. When looking at the cube in excel I get:
Gender Count
F            3
M           4
N           15
Grand Total 20
The grand total is correct, however, it looks like it is grouping the events, so if there are multiple Female members at a particular event, they get rolled up. You can see this better if I pull in member name:
It includes all the names with count 1 ie. 5 Females with count 1, but the gender subtotal is 3 (as it is grouping the gender dimension)
The detail member counts are good, but the rolled up M and F counts are stripping out duplicates. Is there a way to model this in SSAS to preserve the detail member counts when the member dimension is used? Is a many to many the best solution?
This is all using SQL Server 2012 Multi-Dimensional Model. Thanks.

Ok, for starters, if it's a one to many relationship, don't set it up as a many to many! Avoid many to many relationships and really anything other than "regular" relationships.
Second, the tables you pasted the data for aren't the tables you are describing them as, based on the dsv screenshot you included. If your post is confusing to the people who are wanting to help you, they will quickly move on.
It seems that you are not clear on how to construct a star schema. I will lay one out for you and hopefully this can help you on your journey.
fact_member_event:
event_id
member_id
member_event_count
dim_member:
member_id
member_key
member_name
member_gender
dim_event:
event_id
event_name
fact_event:
event_id
event_count
Or alternately, you could drop the fact_event fact table and have a calculated member that uses dimEvent.event.event.allmembers.count. It's a little bit of a weird situation that I would want to play with, but I would start with the above.
Also if you post back and show query results, you should make it clear what columns you are displaying. I see "count" in your query above, but nowhere in the star schema do I see "member count"
as a field.. I guess that's event count?
Hope this helps,
Ken

Plea for example - Many-to-Many CMP EJB

I am attempting to create an EJB that uses Container Managed Persistence,
but my situation seems to be an odd one. The EJB needs to have a
Many-to-Many relationship to itself, because the object is Hierarchical.
Because this is my first EJB I am having a hard time with all of the
deployment descriptors.
I am asking for an example of any Many-to-Many EJB relationship that uses
Weblogic's built-in link table creation to make the relationship (that
works). I realize that there are confidentiality issues with many people
releasing code. I will make any promise (short of selling my soul) that the
code will be safe and promply destroyed immediately after inspection.
Thanks for any help,

The following describes how to establish a self many-to-many relationship with regards to Product having many parent products and many children products. I have attached the example files as well. Most of these files were generated using EJBGen. I would highly recommend it...
EJB
v Navigating from a Product to its parent Products results in getParents() method in Product
§ Since a Product can have many parents the return type of getParents() method is
java.util.Collection
§ Calling setParents() method results in establishing the new links between this Parent and
parent Products
§ Adding a Product as Parent to the Product results in establishing a new link between this
Product and other Product as parent
· This product is made available in the collection of children in the other Product
§ Removing a Product as Parent to the Product results in breaking a link between this
Product and the other Product as parent
· This product is also removed from the collection of children in the other Product
v Navigating from a Product to its children Products results in getChildren() method in Product
§ Since a Product can have many children the return type of getChildren() method is
java.util.Collection
§ Calling setChildren() method results in breaking the old links between this Product and
children Products
§ Adding a Product as child to the Product results in establishing a new link between this
Product and other Product as child
· This product is made available in the collection of parents in the other Product
§ Removing a Product as child from the Product results in breaking a link between this
Product and the other Product as child
· This Product is also removed from the collection of parents in the other Product.
v Example: ProductBean
Ø DataBase
v For a many-to-many relationship define a new associative (join) table
v Define a new Parent_Child_Product associative table
v The Parent_Child_Product has compound primary keys: Parent_Product_ID and
Child_Product_ID
v Parent_Product_ID and Child_Product_ID are foreign keys to Product table
v Example: Product, Parent_Child_Product
Ø Deployment Descriptors
v ejb-jar.xml
§ Within <ejb-jar>.<relationships>.<ejb-relation> define the following:
· Name of the relationship
o Example: <ejb-relation-name>Parent-Product-Children</ejb-relation-name>
· Role from the parent Product side

Dynamic table - some fields of different rows in one column

Hey guys,
i have the following problem:
i habe a itab with some data like:
name | id | date | number
pete | 1 | 27.07 |    2
pete | 1 | 28.07 |    2
pete | 1 | 30.07 |    2
ann   | 1 | 28.07 |    3
ann   | 2 | 30.07 |    2
the user can define a period of time, e.g. 28-29.07
so my dynamic table will consist of the "hard" columns name and id and the dynamic added columns for every day:
name | id | 28.07 | 29.07
that's what i already have!
so my problem is, that i have to read the data from the itab into the new dynamic table (field-symbol) like:
name | id | 28.07 | 29.07
pete   | 1 |    2     |    2
ann    | 1 |    3     |    -
i hope you can understand what i want! please give me code sample or a example report!
many thanks in adance!
best regards,
ludwig

hey Asik, you have understand what i want!
here is my table:
http://img181.imageshack.us/my.php?image=wh20080916113004ym8.png
after the loop, the 4 rows should be in my field-symbol only one row (no sum)!
but after the loop, there are to many rows! only one row is needed!
Look at the screenshot:
http://img185.imageshack.us/my.php?image=wh20080916113547wl0.png
So the second row at column "tag20080801" should be initial and with the next loop, the next day "tag20080730" should be filled with the number!

How to create a multiple PDF-form outputs into one PDF?

I`d like to create a PDF document with a few pages in it, build from different PDF-forms using many form-function calls. Where each PDF-form can use its own interface.

Sorry, but making single PDF from many smartforms is not what I want to achieve. I wold like to know how to get one PDF document made by ALC-forms.
In my example I have many PDF documents. So, how to get (or put) them all in one PDF?
ps: the way to get one PDF from smartforms is also here:

How to submit InfoPath form data to multiple SharePoint lists at one time?

Hi,
I'm looking for a way to submit certain data in InfoPath form to separate SharePoint lists at the same time. I have a form that has two views with many data in them. I want to keep these data in separate SharePoint list besides keeping them in the XML. I know that you can submit to a form library using SharePoint document library data connection, but I'm not sure if you can use several data connections for submitting data to multiple SharePoint lists. Is it only possible to do using code? If yes, can anyone show a sample. I have never coded in InfoPath, though I used C# a lot in .Net.
Thank you!Regards,
R.D.M.

This is an old thread but I tripped over a codeless method to do this with OOB InfoPath 2010 and SP 2010.
Assuming your main InfoPath form is published to a document library with the promoted fields that you want to see.
Publish your form to a new document library to capture the secondary data fields that you want separated out.
Using the Publishing Wizard do the following:
Go to – File then Publish
Select SharePoint Server “ Publish form to a SharePoint Library”
Enter location of your SharePoint or InfoPath Forms Services Site:
accept the default in this field from the first published event
Next screen, keep the default or change it, Form Library, Site Content Type or Admin Approved
Next screen, What do you want to do?
Create a new form library
Add new document library name and description
Next screen, Remove all promoted fields not applicable to the new library and add all of the ones you want to see data for.
Click Next and Publish
Come back into the form: If you don’t have buttons added directly to the form to submit or update, add them.
Create a new Action rule on the button
Label the rule to keep it straight
Condition, occurs when button clicked
Add action, Submit data
Use data connection to the second library created
Create a second new Action rule on the same button
Label the rule to keep it straight
Condition, occurs when button clicked
Add action, Submit data
Use original data connection to the library
Then you can add another action to close the form or do whatever you need.
Republish the form to both libraries to set the template for both.
File – Publish – SharePoint Server
Select Secondary library from drop down follow the rest of the prompts
Follow step 5a again, select Primary library from drop down, Add back in all of the promoted fields needed for the primary library and follow the prompts.
DOCUMENT YOUR FORM WELL FOR MAINTENANCE
Special considerations, your primary library needs a unique ID to reference in your secondary library.
Your secondary library will need a unique ID that is not related to the primary if you are going to store multiple records for a single primary library reference.
Example: One form, multiple updates.

How do I copy parts of layers from one AI doc into a new AI doc and keep/create same layer names?

How do I copy PARTS of layers containing many objects from one CS5 AI (v.15.0.2) doc into a new CS5 AI doc and keep/create the same layer names?
To start with, I have one fairly complex AI document with 100 layers, with several hundred items in each layer. For example, one layer named "Stars" contains 400 separate stars (not grouped), another layer named "Crosses" contains 300 separate crosses, and a 3rd layer named "Text" contains 200 separate words (not outlined).
If I select, by marqueeing a section of the image/artboard, some (but not all) of the individual items contained in the several layers, then paste that selection into a new CS5 AI doc, I cannot get them to create new layers of the same name. Instead they go into one general layer (e.g. "Layer 101") as a jumble of discrete, but unorganized objects (no layers or sublayers). In other words, I have lost the 3 main layers from which I selected a bunch of objects.
Checking "Paste Remembers Layers" has no effect on this result. In fact "Paste Remembers Layers" does not remember layers at all. Only if I select ALL the items in the several layers will it paste those layers by those names into the new doc (or create new layers of the same names).
Of course it is a COLOSSAL waste of time copying the ENTIRE document, then pasting the WHOLE thing into the new doc (with layers retained), then deleting the parts I DON'T need, so please don't suggest that as the solution.

No Monica, nothing in Plug-ins other than the standard installed items (extensions, filters, formats, etc.). No 3rd-part clipboard extension on my computer that I'm aware of, either. All frustratingly basic. And my other CS5 Adobe programs appear to work well, at least to the extent that I am familiar with them.
So, from what I can tell of the various comments (thanks to all of you), am I correct in thinking that it seems I can't, in fact, do what all of you can do (that is, copy some objects from some layers in one doc and paste into another doc preserving those same layers by name and organization, and each containing the correct objects from each original layer)?
If so, that solves half my issue - "is it supposed to be possible to do it"; leaving just the other half - "why can't I do it too".
I'll get those screenshots made and posted later just in case I haven't adequately described the issue, or y'all haven't understood it.

How to create a theme with more than one master-slide size defined?

I would like to create a Keynote theme that has more than one size of page defined - for example one for on-screen show, and one for printing.
I noticed that the stock themes, and those from theme vendors, come with multiple page dimensions, and that the master slide layouts for the 'same' master slide appear to be designed differently for the different sizes.
How do I create themes like this in Keynote? I cannot find any information about this in the Keynote manual. I have worked out how to change the master slide dimensions, but not how to tell Keynote that the layout I've created for a slide is for a particular set of dimensions. So when I look at my theme in the theme browser, I only see the dimensions I had selected last time I saved my theme showing.
Any help most appreciated.

The same reason that Apple and 3rd Party vendors put multi-size templates in one file I expect. I am trying to construct an in-house standard template for use in our company, and it is easier to manage if there is only one file to send to people rather than many - both initially and for subsequent edits / updates to the template.
Of course it would be possible to create several templates (one for each size). But since it is clear that templates can be combined, it appears sensible to do this - unless the doing of it is horridly complicated

[ADF] Adding/deleting entries in a many-to-many relationship

I am using JDeveloper 10.1.3 and the ADF BC / ADF Model / ADF Faces / JSF technology stack.
For this question, I am using the SRDemo application as an example, specifically the many-to-many relationship between USERS and PRODUCTS (the Staff Expertise relationship), outlined in red in this schema diagram: Image Link
Users may have any number of product expertise areas and many users may have the same product expertise area. For the purposes of this example I have added two reference fields from the PRODUCT table into the ExpertiseAreas VO (Name and Description), outlined in red in this data control palette section: Image Link
I have created a page which shows the details of a user (1), along with a table showing the expertise areas the user has (3), and a table of all the products available (2), numbered on this design page: Image Link and corresponding to the numbered data controls on this data control palette section: Image Link, where 1 is rendered as an ADF Read-only Form, 2 is an ADF Read-only Table with a tableSelectMany element in the selection facet, and 3 is also an ADF Read-only Table.
What I am trying to do is have the tableSelectMany element reflect which of the products are linked to the current user in the expertise areas relationship (by having the checkbox for currently linked products checked), and when you check or uncheck a product's checkbox, it should add or remove the row in the EXPERTISE_AREAS intersection table, respectively (asume for this example that there are default values for Expertise Level and Notes).
So far I have been following the process used in section 19.8 of the ADF Developer's Guide for Forms/4GL Developers, which describes how to set up a selectManyShuttle which implements the adding and deleting functionality. So I have a Client Interface method in the Application Module, updateSkillsForCurrentStaff (described in section 10.6.7.2), and I have a selection listener for the assignment table in the backing bean for the page, which calls the updateSkillsForCurrentStaff method:
public void selectionChanged(SelectionEvent event)
BindingContainer bc = getBindings();
DCIteratorBinding productsIB = (DCIteratorBinding)bc.get("ProductListIterator");
Set keys = getTable1().getSelectionState().getKeySet();
Iterator iter = keys.iterator();
List productIds = new Vector();
while (iter.hasNext())
    String product = ((Key)iter.next()).toStringFormat(true);
    productsIB.setCurrentRowWithKey(product);
    ViewRowImpl productRow = (ViewRowImpl)productsIB.getCurrentRow();
    Number productId = (Number)productRow.getAttribute("Id");
    productIds.add(productId);
OperationBinding ob = bc.getOperationBinding("updateSkillsForCurrentStaff");
Map pm = ob.getParamsMap();
pm.put("productIds", productIds);
ob.execute();
All of this works, but I can't work out how to link the selection state of the assignment table to the expertise areas that are linked to the user. Also I think the method listing above must be a bit of a hack, but I don't know enough about this to know if there's an easier way of doing it.
Any help is appreciated.

Have a look at this example I cooked up for you.

It might not be the first way one thinks to implement something, but it illustrates a very interesting, model-centric approach to the problem you propose.
My feelings won't be hurt if you prefer a more view-centric approach, but I wanted to illustrate what was a maximally-model-centric solution (in fact, which doesn't even require a backing bean!) If you like a more view-centric approach, I can help you figure out what's wrong with your key-handling above. For one, I would probably start by passing the Set of Key's directly to the middle tier application module method to eliminate client-side code.
Check it out and let me know what you think. Try it directly in the Business Components Tester to appreciate one of the benefits a model-centric solution can bring.

Example: One to many & Many to One..
