Help for conditional indexing in LV 2012?

Not that I need it, but I could not find any help on the new LV 2012 Conditional Indexing feature. It appears in the contextual menu, but the contextual help does not provide any hint of what this is, and it's nowhere to be found in the Help:
Solved!
Go to Solution.

Sorry it took so long to get back. I had to download LV2012. I think I still need to download the patch. And also setup all of my setting and addons. VIPM will be busy for the rest of the day.
Anyways, your benchmark is flawed. Add outputs to the arrays and you will get radically different results. I think some of your loops didn't exactly iterate the 10000 times since there was no output. And I have no clue what you were trying to show with the second benchmark.
I didn't edit the labels yet. So for those who haven't looked at the VI, "x/y" is the time for pre-allocating and keeping only what is needed. "x/y 2" is the same except with another data type. "x/y 3" is using the build array. "x/y 4" is using the new conditional indexing feature. Each one is looped 10000 times and the average is given (in ms).
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Help for conditional formatting of a chart query!!!!!

Dear Gurus,
can Anyone give me a step by step for conditional formatting on the chart?
I want my charts in my queries to be for example:
green color when actual data <= version,
Yellow if actual > version & 101%, red if actual >=101%.
Thank You very much for sharing your Knowledge.

Hi Des,
You can achieve this through exceptional reporting. Choose your query & execute the report. click on the 'Exceptions & Conditions' button. create the exception you wish to have by choosing version & your key figure, in your case. when you click 'Transfer' it automatically gets activated & you can be able to view the colors set by you.

Help for with slow, glitchy (late 2012) iMac

This is an ANSWER and not a request for help. I didn't know where to post this and apologize for stepping where I shouldn't.
I have a Late 2012 iMac that has been crashing, running slow, and now worse; all my documents and everything in Finder have disappeared. I discovered a fix that may help others with similar issues. I use my iMac for use with Logic Pro X and Mainstage where freezeups are a disaster. I thought about this awhile and realized I had installed a new USB 3.0 external hard disk a few months ago when this issue began. I began to experience more and more crashes and extremely slow performance. Beach-balls and slow performance were common. But the last straw was when everything in Finder disappeared. My Document and Application folders were empty. If I clicked on "About This Mac" I saw nothing. It took two tries to prove my theory, but here's what I did to make "the fix". I unplugged the USB 3.0 drive and all USB and external devices. I did a restore of OSX Mt Lion. All was back to normal. But after plugging in the USB 3.0 drive, all the afore mentioned problems came back. I did one more restore, this time NOT connecting the USB 3.0 external hard disk. Now I have gone some time and my iMac's speed is back to "incredible", no beach balls or any sign of slow performance in recording or running any other app. Apparently, the 2012 iMac; although spec'ed to be USB 3.0 compatible, may not be all that compatible. Hope this helps someone!

Likely the external drive is bad or defective cable.

Please help for create index for table in db2

Dear Consultants,
Our Production Servers have a problem, when user input materials in t-code VA01, the check data take long time to complete.
I was create a incident on SAP Portal and they recommended to create a new index on table:
VBRP in the order MANDT, AUBEL and AUPOS.
but we don't sure how to do this, please help us !
The SAP consultant message:
" It was identified that there is one SQL statement which was
responsible for the majority of the time spent during the VA01
transaction. It accounted for around 49 seconds.
The SQL statement was analysed and a selectivity analysis was carried
out on certain fields specified in the WHERE clause. The statement is
currently executed via a full table scan which is not an efficient
access. It is therefore recommended to create a new index on table
VBRP in the order MANDT, AUBEL and AUPOS. "
Our System Landscape IS : DEV -> QAS -> Production and DataBase server : db2 9.07 , SAP ECC 6.0, windows server 2008

This is fixed now. Thanks a lot for helping out this. I have two questions.
1) I am seeing very slowness when selecting the select list. Will these java code require much resource?
2) I need to put this logic in many screens for many columns. So having these many application process and application items and java code, will the application performance get a hit? I know that application process are on-demand and get called only when required.

Regarding Condition Index

Hi All,
With regards to condition index I have made the required tick in the condition type now when I am going into the master data with regards to creating condition records selecting the condition index tab by giving the input as the condition type, the system says that there are no records found, eventhough I have created the sales order in the system, the access sequence consists of line item and sales order please advise if any other configuration needs to be done for condition index and how do I check if the configuration is complete.
Kind Regards
Atul

Hi Condition indes only Specifies whether the system updates one or more condition indices when maintaining condition records. It depends whether you had created the combination of condition recored to determin if you can find the existing one, please be sure you had created the condition record via vk11.

Conditional Help for Multiple Customers

In the company I work for we have a software product that is configurable for different customers. I have a master online help that contains ALL the components. When we are sending a particular iteration of the software to a customer with their specific set of components exposed, I have to generate a specific help for this set of components. I have all the different components conditionalised so that I can pick and choose the components needed for each customer. Development here are trying to automate the software build process and I am wondering if there is any way for our build process, via a script or something, to pick the conditionalised topics from the master help system so that we do not have to generate a new help for every customer? Any help or advice would be great. Thanks.

Creating an index: it's not possible to select a tablespace for the index

Hi,
we are using SQL-Developer Version 3.0.04.
When creating an index it's not possible to select a tablespace for the index. The only choice which is offered by SQL-Developer is <DEFAULT>.
The user itself has privileges on several other tablespaces - and therefore not just only on the default tablespace of the user.
Any help will be appreciated
Rgds
JH

Hi JH,
Well, the capability is somewhat buried in the UI, but it is there.
In the Create Index dialog ...
1. Tick the "Advanced" check-box in the upper right-hand corner.
2. Select "Properties" from the left-hand list (Definition, Properties, Partitions, DDL).
3. Click the Storage Options... button
4. Use the drop-down list to select the desired tablespace.
Return to (2.) and select DDL to see that your tablespace choice is present.
Regards,
Gary
SQL Developer Team
Edited by: Gary Graham on Mar 7, 2012 5:06 PM
And if all you see in the drop-down list is <DEFAULT>, then I would suggest rechecking the user's privileges. Or provide more details about your environment: OS / Database / JDK version, and so on.

How to update a large (over 4 million item) List(Of Byte) quickly by altering indexes contained in a Dictionary(Of Integer, Byte) where the Dictionaries keys are the indexes in the List(Of Byte) that need to be changed to the values for those indexes?

   I'm having some difficulty with transferring images from a UDP Client to a UDP Server. The issue is receiving the bytes necessary to update an original image sent from the Client to the Server and updating the Servers List(Of Byte) with the
new bytes replacing bytes in that list. This is a simplex connection where the Sever receives and the Client sends to utilize the least amount of bandwidth for a "Remote Desktop" style application where the Server side needs image updates of whatever
occurs on the Client desktop.
   So far I can tranfer images with no issue. The images can be be any image type (.Bmp, .Gif, .JPeg, .Png, etc). I was working with sending .JPeg's as they appear to be the smallest size image when a Bitmap is saved to a memory stream as type
.JPeg. And then I am using GZip to compress that byte array again so it is much smaller. However on a loopback on my NIC the speed for sending a full size screen capture is not very fast as the Server updates fairly slowly unless the Clients screen capture
Bitmap is reduced in size to about 1/3'd of the original size. Then about 12000 bytes or less are sent for each update.
   Due to .JPeg compression I suppose there is no way to get the difference in bytes between two .JPegs and only send those when something occurs on the desktop that alters the desktop screen capture image. Therefore I went to using .Bmp's as each
.Bmp contains the same number of bytes in its array regardless of the image alterations on the desktop. So I suppose the difference in bytes from a second screen capture and an inital screen capture are what is different in the second image from the initial
image.
   What I have done so far is save an initial Bitmap of a screen capture using a memory stream and saving as type .Bmp which takes less than 93 milliseconds for 4196406 bytes. Compressing that takes less than 118 milliseconds to 197325 bytes for
the current windows on the desktop. When that is done PictureBox1 is updated from nothing to the captured image as the PictureBox's background image with image layout zoom and the PictureBox sized at 1/2 my screens width and 1/2 my screens height.
   Then I save a new Bitmap the same way which now contains different image information as the PictureBox is now displaying an image so its back color is no longer displayed (solid color Aqua) and the cursor has moved to a different location. The
second Bitmap is also 4196406 in bytes and compressed it was 315473 bytes in size.
   I also just found code from this link Converting a Bitmap to a Byte Array (and Byte Array to Bitmap) which gets a byte array
directly from a Bitmap and the size of that is 3148800 for whatever is full screen captured on my laptop. So I should be able to work with smaller byte arrays at some point.
   The issue I'm having is that once the Client sends an image of the desktop to the Server I only want to update the server with any differences occuring on the Clients desktop. So what I have done is compare the first screen captures bytes (stored
in a List(Of Byte)) to the second screen captures bytes (stored in a List(Of Byte)) by using a For/Next for 0 to 4196405 where if a byte in the first screen captures List is not equal to a byte in the second screen captures List I add the index and byte of
the second screen captures list to a Dictionary(Of Integer, Byte). The Dictionary then only contains the indexes and bytes that are different between the first screen capture and second screen capture. This takes about 125 milliseconds which I think is pretty
fast for 4196406 byte comparison using a For/Next and adding all the different bytes and indexes for each byte to a Dictionary.
    The difference in Bytes between the inital screen capture and the second screen capture is 242587 as an example which changes of course. For that amount of bytes the Dictionary contains 242587 integers as indexes and 242587 bytes as different
bytes totaling 485174 bytes for both arrays (keys, values). Compressed the indexes go from 242587 to 43489 bytes and the values go from 242587 to 34982 bytes. Which means I will have to send 78, 481 bytes from the Client to the Server to update the display
on the server. Quite smaller than the original 4196406 bytes of the second Bitmap saved to type .Bmp or the compressed size of that array which was 315473 bytes. Plus a few bytes I add as overhead so the server knows when an image array ends and how many packets
were sent for the array so it can discard complete arrays if necessary since UDP is lossfull although probably not so much in current networks like it may originally have been when the internet started.
    In reality the data from the Client to the Server will mostly be the cursor as it moves and updating the Server image with only a few hundred bytes I would imagine at a time. Or when the cursor selects a Button for example and the Buttons
color changes causing those differences in the original screen capture.
   But the problem is if I send the Dictionaries Indexes and Bytes to the Server then I need to update the original Bitmap List(Of Byte) on the server by removing the Bytes in the received informations Index locations array from the Servers Bitmap
List(Of Byte) and replacing those Bytes with the Bytes in the received informations Byte array. This takes so long using a For/Next for however many indexes are in the received informations Index array to update the Bitmap List(Of Byte) on the server using
"Bmp1Bytes.RemoveAt(Index As Integer)" followed by "Bmp1Bytes.Insert(Index As Integer, Item As Byte)" in the For/Next.
    I've tried various For/Next statements including using a new List(Of Byte) with If statements so If the the integer for the For/Next ='s the Key in a Dictionary(Of Integer, Byte) using a Counter to provide the Dictionaries Key value then
the Dictionaries byte value will be added to the List(Of Byte) and the counter will increas by one Else the List(Of Byte) adds the original "Bmp1Bytes" byte at that index to the new List(Of Byte). This takes forever also.
   I also tried the same For/Next adding to a new Dictionary(Of Integer, Byte) but that takes forever too.
   I think I could use RemoveRange and AddRange to speed things up. But I don't know how to retrieve a contiguous range of indexes in the received indexes that need to be updated in the servers "Bmp1Bytes" List(Of Byte) from the received
array of indexes and bytes which are in a Dictionary(Of Integer, Byte). But I believe this would even be slower than some realistic method for replacing all Bytes in a List(Of Byte) when I have the indexes that need to be replaced and the bytes to replace
them with.
   Even if I just used AddRange on a new List(Of Byte) to add ranges of bytes from the original "Bmp1Bytes" and the changes from the Dictionary(Of Integer, Byte) I think this would be rather slow. Although I don't know how to do that
by getting contiguous ranges of indexes from the Dictionaries keys.
   So I was wondering if there is some method perhaps using Linq or IEnumerable which I've been unable to figure anything out which could do this.
   I do have some copy and pasted code which I don't understand how it works that I am using which I would guess could be altered for doing something like this but I can't find information that provides how the code works. Or even if I did
maybe I can't understand it. Like the code below which is extremely fast.
   Dim strArray() As String = Array.ConvertAll(Of Integer, String)(BmpComparisonDict.Keys.ToArray, Function(x) x.ToString())

Monkeyboy,
That was quite a bit to read, but still a bit unclear. Could you put a specific list of goals/questions, asked in the smallest possible form?
It seems like either you're making a program that monitors activity on your computer, or you're writing some kind of remote pc app.
When you do get your bytes from using lockbits, keep in mind all the files header info would be lost. I think retaining the header info is worth the extra bytes.
The other, thing: I'm not sure if you're taking 32bpp screen shots, but also keep in mind that the "whole desktop" is the final destination for blended graphics, if that makes sense. What I mean is that there is no need to capture an "alpha"
channel for a desktop screenshot, as alpha would always be 255, this could save you 1 byte per pixel captured... Theres nothing "behind" the desktop, therefore no alpha, and every window shown above the desktop is already blended. I suggest using
24Bpp for a full screen capture.
Your X,Y information for the mouse could be stored as UINT16, this would save you a measly 2 bytes per location update/save.
When you update your byte arrays, maybe you can turn the array into a stream and write to whatever index, however many bytes, that should prevent a "Shift" of bytes, and instead overwrite any bytes that "get in the way".
ex
Dim example As String = "This is an example."
Dim insertString As String = "was"
Dim insertBytes As Byte() = System.Text.Encoding.ASCII.GetBytes(insertString)
Dim bytes As Byte() = System.Text.Encoding.ASCII.GetBytes(example)
Dim modifiedBytes As Byte() = {}
Using ms As New System.IO.MemoryStream(bytes)
ms.Position = 5
ms.Write(insertBytes, 0, 3)
modifiedBytes = ms.ToArray
End Using
Dim newString As String = System.Text.Encoding.ASCII.GetString(modifiedBytes)
'Notice how below there isn't the word "is" anymore, and that there isn't a
'space.
'This demonstrates that you overwrite existing data, versus shifting everything to
'the right.
'Returns: This wasan example.

Joel Engineer may have answered but I'm not sure. As I'm still too tired to understand that yet and research what he said in order to figure it out yet.
But maybe the code below can provide the concept of the operation with the comments in it. But seeing as how I'm still tired it may be confused.

How to create a F4 help for a report selection screen field

hi,
can any one guide me to create F4 help for a field in a selection screen in a report program,plz give me a sample code

hi,
Here are the following ways
1.with the help of match code objects we can create the F4 Functionality for Field.
Syntax is :
PARAMETERS: p_org LIKE t527x-orgeh MATCHCODE OBJECT zorg.
2. One more thing is we can do it with Search Help's also.
3. Even we can do it HELP Views also.
Help Views:
You have to create a help view if a view with outer join is needed as selection method of a search help
The selection method of a search help is either a table or a view. If you have to select data from several tables for the search help, you should generally use a database view as selection method. However, a database view always implements an inner join. If you need a view with outer join for the data selection, you have to use a help view as selection method.
All the tables included in a help view must be linked with foreign keys. Only foreign keys that have certain attributes can be used here. The first table to be inserted in the help view is called the primary table of the help view. The tables added to this primary table with foreign keys are called secondary tables.
The functionality of a help view has changed significantly between Release 3.0 and Release 4.0. In Release 3.0, a help view was automatically displayed for the input help (F4 help) for all the fields that were checked against the primary table of the help view. This is no longer the case in Release 4.0.
As of Release 4.0, you must explicitly create a search help that must be linked with the fields for which it is offered (see Linking Search Helps with Screen Fields ).
Existing help views are automatically migrated to search helps when you upgrade to a release higher than 4.0.
A help view implements an outer join, i.e. all the contents of the primary table of the help view are always displayed. You therefore should not formulate a selection condition for fields in one of the secondary tables of the help view. If records of these secondary tables cannot be read as a result of this selection condition, the contents of the corresponding fields of the secondary table are displayed with initial value.

How to get search help for 2nd parameter based on the 1st parameter value

Hi all!
   I have 2 parameters (material no, revision level). I have created a search help for revision level. It has an importing parameter :material no. and one exporting parameter : revision level.When I checked it, it's giving the revision values only for the specified.
In my report , I have kept these 2 materials in my selection screen.For revision level , I have added the matchcode object which I have created. When I pressed F4 for revision level, it's giving all the values irrespective of the material no. in the first parameter. How to solve it? Please suggest.
