Does Coloring Of Rows and Column in Query effect the Performance of Query

Hi to all,
Does Coloring of Rows and Column in Query via WAD or Report designer , will effect the performance of query.
If yes, then how.
What are the key factor should we consider while design of query in regards of Query performance.
I shall ne thankful to you for this.
Regards
Pavneet Rana

There will not be any significance perofrmance issue for Colouring the rows or columns...
But there are various performance parameters which should be looked into while designing a query...
Hope this PPT helps you.

JTable about selection mode, setting a Color to rows and column.

I need an application with a table containing Double and String data. When the table is shown the Double data must be shown as selected. I need a special kind of selection mode similar to MULTIPLE_INTERVAL_SELECTION but it must be a mode as if CONTROL was pressed when the user left clicks the table so he or she can select and deselect columns without deselecting those wich have been selected previously... Besides I need to paint columns and rows only if they have certain conditions. This is an example of what I have done so far... The selection mode is what is really important.

Interesting concept! This is what I have tried and it works, but in the application I need the user to deselect the columns he wants only by left clicking on them... This is the main idea: there will be lots of columns (String and Double data). The user must deselect the Double columns he or she does not want to be processed... Maybe with a boolean array that changes it state if a user left clicks a column... but I suppose this method is called only once to initialize the table, isn't it? Thanks.
<code>
table = new JTable( new MyOwnTableModel() ) {
public boolean isCellSelected(int row, int column) {
MyOwnTableModel model = (MyOwnTableModel) this.getModel();

JTable Problem (table does not show rows and columns)

Hi All,
What the table is suppose to do.
- Load information from a database
- put all the values in the first column
- in the second column put combobox (cell editor with numbers 1-12)
- the 3rd column put another combobox for something else
- the 4th column uses checkbox as an edit
The number of rows of the table should be equal to the number of
record from
the database. If not given it default to 20 (poor but ok for this)
The number of columns is 4.
But the table does not show any rows or
column when I put it inside a
JScrollPane (Otherwise it works).
Please help,
thanks in advance.

I hope you don't expect us to read hundreds of lines of unformatted code? Use the "formatting tags" when you post.
Why are you creating your own TableModel? It looks to me like the DefaultTableModel will store you data. Learn how to use JTable with its DefaultTableModel first. Then if you determine that DefaultTableModel doesn't provide the required functionality you can write your own model.

Key figures in row and column.

Dear all,
I have a requirement in my BEx query to have to key figures in both the row and column. This is the scenario, I have a formula defined in the row which does a total up and the user would like to see this key figure formula in the column while still maintaining all other key figures in the row. How can this be done?
It seems that once I have a key figure in either the column or row I can only use either one- not both at the same time.
Thanks in advance and points will be awarded.

Hi,
You can use KF in either in Row or Column.It's not possible to use in both in rows and columns.

Row and Column Template ?

Trying to create this thing but no matter what I do I keep getting this ridiculous error:
Cannot create a linked row and column template based on
the selected rows. The grid needs to have at least one data row that is
not part of a row and column template.
What does this mean?

You can get your requirement done using the Row and Column Template
You can not save a row and column template with all rows in a report. You have to exclude at least one data row, otherwise you
will get the error that you mentioned.
If you want to save all the rows as a template and re-use it in other report, you can insert a data row at the end of all rows and hide that.
Now you can select the complete row set as a template by excluding the extra data row that you will insert & hide.
If you want to link the template in other reports with same row set you must be very careful with the formatting as you need to apply
inherit formatting before saving the template. I suggest to spend some time with the FR online documentation.

Search row and column for return value

Dear Sir/Madam,
                           I have a problem for searching spreadsheet and hope you can help me out a bit. Im pretty new to Labview and Im currently using Labview 8.0. My task is to search the spreadsheet I have attached in row and column-wise, then return the corresponding value out. I had an attempt in doing this as you can see from the vi that i have attached. I try inputting the 'read from measurement file' into an array and using delete, index and search array I will be able to find the index value for the relevant row and column that i searched for by inputting them into an index array with the orginal array from the 'read from measurement file'.
                          So ultimately, when i enter a row value of 0.5 and a column value of 0.3, my output will be 1.688.
                          I can't see any mistakes in my logic but I getting really strange results, like I can read my data has been entered into an array but when i try deleting the first column and put it into another array, the orginal array with nothing deleted is outputted hence making my search to give out -1 value. So could you take a look please and give me any suggestion that can solve my problem or enhance the code a bit. Thank you for your time.
Best Regards,
Coato
P.s for some reason i can't attached the .lvm file of my data hence i have attached the excel version but i think you need to convert it back to .lvm for the 'read from measurement file' function to work.

Your VI makes absolutely no sense to me, but maybe I don't understand what you are trying to do.
You seem to have dynamic data with 6 signals and 48 points/channel. Now you reshape this into an array of dynamic data with 4x13 elements from which you slice out one row or column, resp. "delete from array" is NOT the correct tool to do this, use "Index array" with one index unwired to get a row or column as 1D array.
So you end up with two 1D arrays of dynamic data that you search for DBL. It is difficult to understand how you want to search for an array element that corresponds to a scalar DBL value of 0.1. Your array elements are NOT DBLs but dynamic data, each containing many signals!
There are two elements on all your data that are "3", the rest are zero. You will never find anything that is 0.1.
Maybe you can convert your original dynamic data to a 2D array with "rows are signals" using "convert from dynamic data", then operate on the 2D array.

Sorry, Please explain.
Please make a VI containing a simple 2D aray as diagram constant that contains e.g. 5x5 typical values. Let us know what kind of result you expect from your algorithm..

Conditional Formating of rows and columns in template(cross tab)

Hi,
I am developing a cross tab report in which I have row header as the year like 2008,2007,2006....column header as months jan,feb,mar...and the data area contains the respective data...I need to format the background color of the rows and columns which are below the date of the report(report is ran for a particular month like mar-08)..I was able to format the background color of all the rows that fall below(ex:08) the year of the report(using <?if@row:row_name<'$first'?> <xsl::attribute name="background-color" xdofo:ctx="incontext">#C0D27F</xsl::attribute><?end if?>)..
and I need to format the 3(till march) columns in the yr 2008
Thanks...

Populate multiple rows and columns based off of a single cell

Does anyone know a way to populate multiple rows and columns based off of the input of a single cell. I'm trying to create a workout tracker that auto populates from a master list of workouts. Example, in A2 the user selects the workout from a drop down menu (St1, St2, St3, etc) and the workout is pulled from the master list and is populated into B2:C5.
I'm using =LOOKUP(A2,Master :: A2:A32,Master :: C2:C32) right now, but it's only drawing the top column. I'm looking for an edit for the formula (or completely new formula) that will place the info from the 1st column of the Master table into the 1st column of the Auto Tracker 1 table and then on down until the 4th column.
Here is a screen shot of what I have now:
And an example of what I'd like to accomplish:
Any and all help is appreciated, and please let me know if there is any more info that I can give that'd help out.

Hi Mike,
Your screenshots show that you have merged some cells in Column A of both tables. That may be the reason why the LOOKUP function is having trouble working out which range of cells to examine.
Hope this helps.
Regards,
Ian.

Get Row and Column info from an Array Cluster

I have an array with a cluster of 2 elements (string and double). Within my application, I am using the State Machine architecture with an Event Structure. When I click on a element within the cluster array, is there a way to retrieve the row and column? I seen the Coordinates within the Mouse Down event but I don't think that will work.
Any ideas?

Rows and column limit on Data Grids

Hello,
anyone know if there's a limit for the number of rows and columns per page in the Data Grids?
Thanks in advance

There is not a limit. There is a default of 1024 rows, but you can change this.

Spry tables: row and column rollover

I have created some tables with spry and they are very nice.
I got the nice rollover effect to work on the rows, but the table
has enough rows and columns that if the the row AND column where
highlighted that would be even better. Is there a way to get the
row and column to highlight at the same time (Essentially
highlighting or intersecting at particular cell or data point)?
Thanks.

Rows and Columns Help

Previously in AI9 when I wanted to modify a matrix I had created using Rows and Columns, I would select the cells of the matrix and then click on Rows and Columns. Now I have CS4 and the documentation says I should be able to do the same thing using Area Type Options. However, when I select the cells of a matrix that I created in AI9, Area Type Options is ghosted out. How do I modify this matrix?

I would copy and paste in front before I try this.
Then select the text that is place the text cursor in a the text frame you want to split or select it with a selection tool.
then see if the Type>Area Text Options are available. They should be.
If not that means they are object paths not Area Text.
Click the Frame with the Area Text tool to make it a Area Text Frame now the options should be available.
The way to tell if these are object paths is to select one and go to the Object >Path>Split into Grid and if that is available then it is an object path.
The text engine and this feature has changed in AI CS1 and that is probably the cause for the translation to get a bit messed up.

How to color Rows and Columns of BI Query

Hi to all,
I have created BI query in query designer, with 2 structures for rows and Columns.
Now I need that certain rows can be colored orange and certain columns as green color.
I knew that it can be done in Query designer, but slice and dice reporting can not be done, which I required in my report.
Is there any way I can do in WAD.
or any other way to do that.
i shall be thankfull to you for this.
