Fill and sort a Matrix/Grid

Hi gurus !!
I want to know if there is a way to fill a Matrix with a sql query or with element of a collection ?
In fact, i want to fill a "grid" or a "matrix" with data wich came from differents tables with join AND have the possibily to sort my "grid" or "matrix" by clicking on RowHeader....
Thanks for your answers.
Laurent.

Hi Laurent,
Like Louis said; you'll need the Grid object. Multiple tables is not possible with matrix (or you must use a very slow recordset object) You'll find a detailed sample in the SDK sample directory or in the SDK Help: UI-API > Reference > Objects > Grid (Click the link below the page "Adding a Grid item")
Or, if you are using SBO 2005 SP01, you can create the Grid in the Screen Painter, you'll find a detailed instruction in the SDK Help by the topic Screen Painter > Working with the Screen Painter
For the sorting; it's not possible 'right out the box', however, you can create it. Capture mouseclicks on the Grid header, and perform a new query on the grid. See the pseudo code below.
switch(pVal.ColUID)
case 1:
 sSQL = "SELECT * FROM FOO ORDER BY column1";
 break;
case 2:
 sSQL = "SELECT * FROM FOO ORDER BY column2";
 break;
MyDataTable.PerformQuery(sSQL);
You might want to make it a bit smarter to sort ascending/descending, but that's up to you...
Hope it helps, good luck,
Rowdy

Dashboards PowerShell Grid Widgets - Grouping and Sorting?

First of all, to those who made Dashboard PowerShell Grid Widgets possible - Thank you, Thank you, Thank you. Love it! So much more power except for the output......
Is there a way to group and sort my results or is it my system? Clicking the column header doesn't seem to work, no personalize option, nor does sorting in the script seem to work.
Thank you.
BTW, it looks like the dashboard is sorting by ID no matter what one does.

Tried it, doesn't work. Moreover, the example in the link uses CreateInstance
whereas I'm using CreateFromObject. Below is my code. If I run the first two lines from the SCOM PS command prompt, I receive a nicely sorted results. Not so in the PowerShell Grid Widget (PsGW). If I change
my sort property to Id, then the output order matches the PsGW. So is this a result of using
CreateFromObject?
Editorial Feedback for the SCOM Team: From all the examples I've seen on the web, and most seem to be derivative of two or three MS examples, the trend appears to be that CreateInstance
is used for the PowerShell Web Browser Widget and everyone seems to be enamored by its capabilities. It sure is pretty, but for my environment doesn't offer a great deal. I feel the real meat and potatoes is PsGW - being
able to create one's own output. I'd love to see more examples of the methods in ScritpContextObject (who's link I'm unable to add) that have nothing to do with the web.
$class = Get-SCOMClass -Name Microsoft.Windows.Cluster.Group
$clstrGrpRes = Get-SCOMClassInstance -Class $class | ? { $_.HealthState -ne "Uninitialized" } | sort-object -property Name -Descending
foreach ($gRes in $clstrGrpRes)
$dataObject = $ScriptContext.CreateFromObject($gRes,"Id=Id,Health=HealthState", $null)
$dataObject["Cluster"] = $gRes.Name.Split(".")[0]
$dataObject["Group Resource"] = $gRes.Name.Split(".")[1]
$dataObject["Hosting Node"] = ($gRes | % { $_.values } | ? { $_.Type.ToString() -eq 'GroupActiveOnNodeDuringDiscovery' } ).value
$ScriptContext.ReturnCollection.Add($dataObject)

How i get data in matrix grid from A/P Invoice

How i get data in matrix grid from A/P Invoice before click add button

Hi,
Are you trying to read the data in the matrix of a system form? Then you only have to look for the matrix with the ID you can see by visualising the System Information in B1 and then directly read from the matrix cells (using columns element in matrix), the DBDataSources are not filled in until the document has been added to the database.
There are many messages in this forum talking about how to read information in matrix item, just make a search for it.
Hope it helps

Standard and sorted itab

what is the diff between standard and sorted itab

Hi Abhay,
check the following explanation.
Standard tables
This is the most appropriate type if you are going to address the individual table entries using the index. Index access is the quickest possible access. You should fill a standard table by appending lines (ABAP APPENDstatement), and read, modify and delete entries by specifying the index (INDEX option with the relevant ABAP command). The access time for a standard table increases in a linear relationship with the number of table entries. If you need key access, standard tables are particularly useful if you can fill and process the table in separate steps. For example, you could fill the table by appending entries, and then sort it. If you use the binary search option (BINARY) with key access, the response time is logarithmically proportional to the number of table entries.
Sorted tables
This is the most appropriate type if you need a table which is sorted as you fill it. You fill sorted tables using the INSERTstatement. Entries are inserted according to the sort sequence defined through the table key. Any illegal entries are recognized as soon as you try to add them to the table. The response time for key access is logarithmically proportional to the number of table entries, since the system always uses a binary search. Sorted tables are particularly useful for partially sequential processing in a LOOP if you specify the beginning of the table key in the WHEREcondition.
Hope this helps.

ALV OO and refreshing the ALV grid

Hi,
i have some problems with my ALV 00 program.
On screen 1 i have to fill in a material number.
For that material i'm getting some data and show in screen 2 in a ALV grid.
Via BACK-button i'm getting back to screen 1 and can fill in another material number.
But the 2nd (and 3rd, etc) time i fill a material, the ALV grid data from material 1 is shown. Even if the internal table I_ALV where the data is, is changed.
What should i do ?
I have initialized the customer container and the grid, but that didn't solved the problem.
regards,
Hans

Hi,
Try clearing and refreshing the alv grid data table in screen 2.
Check with this code. this code is working fine. If we go back and change the input, it is showing the output corresponding to the second input only.
Have you use this method?

mainly performance reason ,if you use sorted internal table then it will have good performance than standard intentable
The internal tables could be catogrised into two.
indexed : standard and sorted tables.
nonindexed: hash tables.
standard table: it is the one we use generally.In this the data is not sorted and the only thing we can do is just process the data with out any restriction on it.
sorted tables: it works in two different manner.
 Frist one: is similar to standard table but the only difference is the data will be filled in a particular manner either ascending or descending.
 Second one: u can also fill the table keeping any field as primary key.now the data will be filled based on that particular key.
Hash tables: u can use this when u want to fill your internal table avoiding the duplication of data.it never permits the duplicate record to be stored in a internal table
Thanks

hi,
For explain more in details.
I need the search result in a table displaying some meta common in the different library.
I've to have the possibility to filter and sort the grid.

Copy sheets and sort

I'm new to numbers, and have been learning how to use the software - great tool!
I have - what should be - a simple request, but I have not found the answer just yet - so I'd like some feedback and direction. I have a sheet set up which I would like to be able to duplicate (on another sheet) where I could sort the second (or third) in a different way, and still only have to make changes on the first sheet as information gets updated/removed/altered.
Thx,
Daryl

Daryl,
Yes, it's pretty simple. You can use three sheets if you wish, but since this is Numbers, you can put the two (or three) tables on one sheet where they are all in view at once and sort to your heart's content.
In the second table, in A1, type an =sign and then click on A1 in the first table. Select A1 in the second table and then grab the little circular handle in the lower right corner and pull it down to Fill the expression to all the other rows in column A. Then select the entire column A and again grab the Fill Handle and pull it across to copy the expressions to all the other columns.
Repeat for the third table.
Any edits in the first table will appear in the other tables, but the sort orders will be independent.

Read and sort a semicolon seperated csv file

Hi all,
I need to sort the given csv file columnwise (alphabatically)... which means the corresponding row/rows also have to be sorted. need help.
the csv file looks like:
Wear;9;;;
;;;Image;1
;;;Area;2
;;;ner;3
;;;Content;1
;;;BContainer;1
;;;View;1
VIEW;10;;;
;;;get;8
;;;ner;1
;;;View;1
ACTIVE;21;;;
;;;Image;1
;;;get;7
;;;Area;4
;;;ner;1
;;;de.vw.mqbkombi.widgets.TransitionContainer;3
;;;Aget2;2
;;;ner2;1
;;;Sget;1
;;;iView;1
The idea is to first sort Wear,VIEW, ACTIVE alphabatically (columnwise), making sure all the rows that they have are also moved.
after that, alphabatically sort all the in-between rows.
would appreciate the help from any expert on csv, excel table.

If you know that your columns never have embedded semicolons, you could call String.split to split each row at semicolons. Although you could leave the results in the arrays that String.split gives, you should probably create a Java class to represent each row. It will make your code easier to understand, and you could also more easily represent numeric values as numbers such as primitive int values (so that they sort correctly as numbers instead of as Strings). Then create a List of instances of that Java class, and sort the list using Collections.sort and a custom java.util.Comparator.Or indeed make it Comparable; but I'd agree this is definitely the way to go.
Also, assuming that all your "secondary" rows, such as:
;;;Image;1
;;;Area;2
refer to the preceding "primary" (Wear;9;;;), I'd suggest you fill in the unsupplied values for them. That will allow you to sort them all in one go. It might also be worth including a type in your "Row" class (maybe as an enum); alternatively you could have two different subclasses of a common Row class.

Cropping and the snap to grid?

When cropping my crop area (square/rectangle/what-have-you) is always snapping to some sort of invisible grid. Is this just how Lr4 works or is there a setting I have settup incorrectly?
And also, When I crop an image I have to move the image into the cropping "square" and cut of a portion of the photo but it's only part of the image I want cropped. And when I do have the image I press "return" and the image appears to be cropped until I go to crop more of the image. Suddenly I'm left back at the state before the previous crop. What am I doing wrong?
Thanks! (I hope this makes sense)

When you are satisfied, you either hit the <enter> key or click on "close" on the crop-panel. It is the bottom of the crop panel, but that is still high on the right-hand panel.
I do not find a "done" in my LR4.0.
...as I am more of a keyboard-guy than mouse-guy I always have to take a look to answer.
<esc> is the shortest way to abandon the crop endeavour and return to where you started invoking the crop (which could be library module if you used the R key).
To my knowledge you can only crop in rectangular way. You have different overlays to guide your decision-making (like spiral etc. - toggle with O key), but the result will always be some rectangle, which can be square, of course.
If you open the padlock you are free to drag the ratio, or you could choose from the drop-down menu "Aspect" one of the presets or enter your own dimensions. LR will recalculate them, though and display maybe different.
So circular is not possible.
For circular you could employ a trick e.g. in Print module: create a watermark or identity plate with circular opening, opaque for the rest.

My iPod touch shows that it is charging but it actually doesn't charge and I've tried to restore/ restart it but the only icon is the charging icon with the battery icon with a bit of red fill and a small lightning icon below it. Can anybody help me?

My iPod touch shows that it is charging but it actually doesn't charge and I've tried to restore/ restart it because the only icon is the charging icon, the one with the battery icon with a bit of red fill and a small lightning icon below it. Can anybody help me and give me solutions before I go to an apple service center?

Place the iPod Touch into DFU mode. This will be similer to what the factory would do to install the iOS onto new iOS devices.
Placing it into DFU mode will allow you to "format" and install the current iOS for that device.
To place your iOS device into DFU mode.
First connect you iOS device to you computer.
Open iTunes if not already open
Now turn off your iOS device using the power swipe.
Press the home and sleep button on your iOS device for 10 seconds.
Release the sleep button but carry on holding down the home button. For another 10 seconds.
Your iOS device should now be on DFU. Click on restore and iTunes will download the lastest iOS for your device.
Hopefully that sorts it if not, you will have to go to a sevice centre or call Apple Care up and get them to collect it and repair it. (replace it)

i want to gather signals from different channels and put these into a matrix which will be updated at every time step. then this matrix should be normalized and the covariance matrix should be calculated. then i want to calculate the eigenvalues of this latter matrix and display them. this last part(normalize,covariance and eigenvalue) can be done either at every time step or after a specific time interval.(i prefer time interval because i don't need that dense information). my main problem is to update the signal matrix. i tried to use "insert into array" but as the matrix should be empty initially it creates problems while trying to connect this to other blocks. the minor problem is i am new and i canno
t find a block to calculate the covariance matrix although i realized that the software has the capability to do it while fitting curves etc. thanks for help.

cigdem,
i attached two examples which show how you can solve the issue with generating the 2D-array (matrix). i annoted it the best way i could, but if you have any questions, feel free to post them.
we have a toolkit called "simultion interface toolkit". you can insert matlab-code in LabVIEW with it and vice versus.
the question about "trigger" is not very specific in this point. normally you trigger the acquisition via a starttrigger and then continue to acquire data either continousely or in "N samples". the time of filling a row the matrix is defined therefore by number of samples and samplerate.

Hi,
Are you trying to place more than one signature on a PDF document?
Please explain the workflow.
