Index of the row where the cursor is clicked

Hi all,
   I need to set some values in table control for the fields where i clicked the cursor. Actually i am using the below code but its not working...
     lo_el_zdcapsc = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).
    lv_sel_index = lo_el_zdcapsc->get_index( ).
         lo_nd_zdcapsc->set_attribute(
       EXPORTING
         index = lv_sel_index
         name = `ZPLANTID`
         value = lv_plant ).
For example I placed the cursor in 3 row at the plant column in my table control. So only 3 row plant value has to be set.
Can anybody tell me how to read the index when a cursor is placed at a particular row.
Regards
Sireesha.

hi
u can use get_index method to get the index of the particular row selected
data: lr_element type ref to if_wd_context_element.
DATA ls_cn_node TYPE wd_this->element_cn_node.
lr_element = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).
* get all declared attributes
lr_element->get_static_attributes(
IMPORTING
static_attributes = ls_cn_node ).
data lv type I.
lv = lr_element->GET_INDEX( ).
u have got the table row values in a strucure , now u can set it to new value
regards,
amit

Trackpad does not work properly

Now impossible to insert the cursor by clicking in one paragraph. I am able to 'find' the cursor by going to another paragraph, then using the arrows to position the cursor in this rogue paragraph.

I use Pages version 4.0.5.
My software is all up to date, 10.6.8 version of OS.
The particular document with the problem is 255 pages and currently at 125,000+ words. One area of a paragraph seems to be at fault and clicking within it has no effect. No cursor appears, no editing is possible and no other input is possible for that part of document.
I can work round this by going to another paragraph, clicking there when the cursor appears, then using the arrows to get the cursor in to position in this 'rogue' paragraph.
I am fairly new to Mac, only having bought this machine at the end of last year but have used it everyday since then. I did have problems with an image editing program supplied with a new Pentax camera but I have stopped using that program after taking the laptop to Apple tech in Sheffield UK who said the laptop was OK but the program was VERY slow and they could see when checking forums that this program was causing problems for other Mac users.
That was about three months ago, so the laptop was deemed to have a clean bill of health then.
I am curious and disappointed more than anything, as I can work around the problem at the moment.
What might be going wrong, how can I correct it, if at all, and should I be worried that there might be a more significant problem developing?

In Lion, sometimes clicking on close button or tabs doesn't respond as if the buttons aren't there, i have to move the cursor away and move back to make them work again, anyone can help me?

I'm not sure if anyone had run into this issue. Clicking the same place on the display sevral times will cause the click to stop working. For example, if i open safari and click on the Show Reading List button, it will work the first time i click it, but stop responding to my command as i click more, as if the button is not there, i have to move away the cursor and click somewhere else and move back to click the button to make it work again. And it happened everywhere, not just the show reading list button. The scrolling and moving are normal.
In fact, I have my trackpad replaced in an apple store for this issue but it turned out this is not a hardware problem, and it is not only my problem. Ironically, i found the same issue on several of the demo Macs inside the apple store. So anyone can help me here? Thanks.

Hi manni394, what version of Firefox are you running now?
Firefox 22 has a new way of setting the default zoom level: it is based on your Windows font size setting. So, if you set Windows fonts to 125% (enlarged 25%), your Firefox pages also will be enlarged 25%. On pages that do not adjust their layout, you may get a horizontal scroll bar.
To reduce the zoom on a page, hold Ctrl and tap the - key (the one on the numeric keypad or the one on the number row of the keyboard). The zoom should be reduced for each tap.
If you want to globally adjust your zoom level to be lower, you can use either of these add-ons:
* [https://addons.mozilla.org/firefox/addon/default-fullzoom-level/ Default FullZoom Level]
* [https://addons.mozilla.org/firefox/addon/nosquint/ NoSquint]
If you already have one of those add-ons, check the default/global zoom level in case it needs to be adjusted.

Update only the row in DB where the cursor are positioned using Write Back

Hello,
I need to have the possibility to create/change values (insert or update data back into the database), dynamically or by typing, in some columns of the physical DB that are mapped in a report request, and that new or changed values could be used as a filter columns in another report request.
So, I have created a new report request in a Subject Area where a certain column of the request result could be editable to make possible change the present value and then write it back in the physical DB.
I have implemented for the column name ‘MOV_VALUE’ the value interaction type format Write Back, and every time I changed any value on this column it updates all rows with this same value from the table ‘MOVEMENTS’.
See below the Template file used in the Write Back table properties:
<?xml version="1.0" encoding="utf-8" ?>
<WebMessageTables xmlns:sawm="com.siebel.analytics.web/message/v1">
<WebMessageTable lang="en-us" system="WriteBack" table="Messages">
<WebMessage name= "UpdateMovementData">
<XML>
<writeBack connectionPool="Connection Pool">
<insert> </insert>
<update> UPDATE MOVEMENTS SET MOV_VALUE=@{c4} </update>

</writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
Is there any possibility to only update the record from where it is the cursor positioned by using the Write Back in the Answers report?
Is necessary to create any condition to the where clause for the update statement? Which conditions?
Thanks in advance.

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.

Well it's too much to read. I was really tired when I wrote it. Even the below is too much to read but perhaps gets the point across of what I would like to do which I think
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 can I get the index of the selected row, ALV

In alv I need to get the selected row id and then calling a screen to show the detailed infomation on this row and providing the ability to update the row.
I know how to do but do not know how to get the selected index of the alv grid.
If it was desired based on just double click, it was ok but I have to provide a button and when it is clicked the detailed screen will come with the selected row details.
Thanks everyone.
Deniz.

Hi Deniz,
While defining the internal table which u pass in ALV_GRID function module, define a field (suppose CHECK type c) in the structure of that internal table.
and while defining field layout, pass the value 'CHECK' to the field BOX_NAME of the layout.
Now, when you execute the report, a selection box will be displayed infront of every record. If you select that record and press the button on application tool bar, the field 'CHECK' in the internal table will be having the value 'X'... By looping throught this internal table where check = 'X', you can achieve your functionality.
Example:
     Structure for output details
TYPES: BEGIN OF GS_OUTPUT.
        INCLUDE STRUCTURE ZAS_WATER_QLTY_REP.
TYPES: CHECK(1) TYPE C,
       END OF GS_OUTPUT.
    Internal    table for output details
DATA: GT_OUTPUT   TYPE STANDARD TABLE OF GS_OUTPUT.
Before calling the function module to display ALV
grid, define a layout usine
Local workarea
DATA: LW_LAYOUT TYPE SLIS_LAYOUT_ALV.
Local constants
CONSTANTS: LC_UFORM TYPE SLIS_FORMNAME
                    VALUE 'ALV_USER_COMMAND'.
LW_LAYOUT-BOX_FIELDNAME = 'CHECK'.    "Field for checkbox
This function module outputs an internal table with whatever
structure in the form of a formatted single- order multi-line list

       EXPORTING
            I_CALLBACK_PROGRAM       = LV_REPID

            OTHERS                   = 2.
and in the form alv_user_command
FORM ALV_USER_COMMAND USING UCOMM SELLINE TYPE SLIS_SELFIELD.

Lets hope that the user command of the push button in * PUSH
when 'PUSH'.
loop at gt_output where check = 'X'.
You can write your code here...
endloop.
endcase.

Hope this helps...

HT1436 My Power Mac G5 will not fully boot without safe mode, it only comes to a blue screen where my cursor duplicates in to 2, (one is frozen, one can move by moving the mouse). What is my problem, and how do I fix it?

My Power Mac G5 will not fully boot without safe mode, it only comes to a blue screen where my cursor duplicates in to 2, (one is frozen, one can move by moving the mouse). What is my problem, and how do I fix it?

Great clue Lukas...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

As I said earlier, it is not possible to get the index. You can only loop and get the current index by doing a field comparison. That too will fail if you have two identical rows.
A better idea would be to have your table as read-only. Have a 'Display/Change' button in your toolbar. You should be able to select a row and click on 'change'. Then you should make the row as editable and do your validations on the edited values. If you have your entire table as editable, it will not be easy to track the changes.
Otherwise, if you want to have the table as editable only, then you can get the changed values using the context change log. Refer to web dynpro component DEMO_CONTEXT_CHANGES to see how this works. You will not get the index, but you will get all the changes that have been done to the context after the last binding.

How do I find the index of a row of a group in a presentation?

I am using a BPM Object Presentation for this and the code is in PBL. From a method (triggered by an event) I need to find out the current row, the index within a Group. (In this case I am referring to the Group array widget, not a user group.)
The specific implementation is as follows:
1. Each row of the group has a button named "Edit Topic"
2. The user clicks the button
3. The action for that button calls the method EditTopic()
4. The method EditTopic() needs to know which row it was triggered from.
Thanks in advance.

Hi,
You can retrieve the zero based value of the row in a Group clicked if you add a method inside of the group (make sure it's inside the group and not in the parent BPM Object).
The presentation's property for the push button inside the group has to be designated as an "action" (vs submit, save or cancel). Name the method associated with the push button in the group something like "getLineClicked()".
The method only needs to have this one line of logic:
lineSelected as Int = orderLines.indexOf(this)
This will give you the zero based index of the row in the group they picked.
Hope this helps,
Dan

How to know the number of rows in a cursor?

Hi all,
How can i know how many rows a cursor has ?
Glen

dbms_sql... you can use when you want to know how many lines of code the cursor has.
If you want to know how many rows it will fetch, you have to fetch all rows - the number of rows actually fetched are assigned to the variable <cursor_name>%ROWCOUNT.
When you don´t want to fetch all rows, all you can do is count(*)...

How to get the index of table row without selection?

Hi all,
I have an table designed in XML view.Now i have added an change method for qty cell "valqty". When user inputs the qty in the cell and press enter this method is triggered now I want to know which index of the table is currently edited.Through which i can get the value of other cell in the same row.
NOTE: The table row doesn't have selection either multiple or single
I tried the following inside the valqty method but it now working
this.getValue();
this.getBindingContext().getProperty('PRD_NUM');
<Table id="idProductsTable"
inset="false"
items="{oModel>/deliverylist}"
visibleRowCount= "7"
mode="MultiSelect"
modeAnimationOn="true">
<headerToolbar>
<Toolbar>
<Label text="Products"></Label>
</Toolbar>
</headerToolbar>
<columns>
<Column
minScreenWidth="Tablet"
demandPopin="true">
<Text text="Order" />
</Column>
<Column
minScreenWidth="Tablet"
demandPopin="true">
<Text text="Quantity" />
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{oModel>PRD_NUM}" />
<Input value="{oModel>DEL_QUAN}" change="valqty" maxLength="13" />
</cells>
</ColumnListItem>
</items>
</Table>
Thanks

Thanks Robin,
But in my case oEvent.getSource() is returning the cell instance and
oEvent.getSource().getBindingContext() is undefined
Hence not getting the value
I also tried the following
oEvent.getSource().getParent().getParent().indexOfItem()
But index returned is -1

TablePopin: Identifying the row where an action of a popin occured

Hi,
i want to use the TablePopin UI-element. The popin can be opened for more than one row at the same time. In the popin some actions might occur (like actions of buttons etc.) My problem is how to identify the row where the action occured. I saw a solution in the wiki using some modifcation of the actions ( https://www.sdn.sap.com/irj/sdn/wiki?path=/display/wdjava/how%2bto%2bimplement%2btablepopin ). It works quite good. However, it will become a pain if you have not only one table but various tables with popin-elements and if you have not only one action but various actions. So, i wonder if there is any easier way to identify the specific row an action occured.

hi
please go through this link
