Cl_wd_table - enable/disable certain cells

Hello together,
I'm looking for a good solution to enable/disable certain cells in a table.
For example I have the following table (the real table is more complex - with buttons and so on...):
User
ToDo
State
A
Todo1
Done
B
Todo2
In Process
A
Todo3
In Process
B
Todo4
Done
I have different users which are working on this tabe:
- Administrator: Can edit whole table (except State column)
- Employee: Can only edit State Column where he is assigned
I think it would be difficult to work with context attributs in this case?
Is it possible to Loop over all table lines an set "enabled" Attribut in the coding?
Best Regards

ALV: how to disable editable cell and F4 in certain rows only.

I am building a table maintenance front-end with an ALV grid using OOP concept. Certain fields are editable and also have customised search helps assigned to them in the ALV structure defined for the grid. What I want is where I have identified an entry in my database table as being locked by another user, I want to grey the line out on the ALV grid so that the entry cannot be edited and not have f4 input whilst this entry is locked by another user.
I can grey the line out or disable F4 but not both at the same time. If I disable the cells of the row concerned using MC_STYLE_DISABLED, the F4 is still active and will change the contents of the cell concerned via the data_changed event method in CL_GUI_ALV_GRID.
I have used MC_STYLE_DISABLED where I have declared a layout in my table similiar to this:
DATA: BEGIN OF OUTPUT OCCURS 0,
FIELD1,
FIELD2,
STYLE TYPE LVC_T_STYL,
LOCK TYPE C.
END OF OUTPUT.
DATA: ls_celltab TYPE lvc_s_styl.
* Where lock identified, field LOCK set to 'X'.
LOOP AT OUTPUT where lock = 'X'.
ls_celltab-fieldname = 'FIELD1'.
ls_celltab-style = cl_gui_alv_grid=>mc_style_disabled.
APPEND ls_celltab TO OUTPUT-STYLE.
ls_celltab-fieldname = 'FIELD2'.
ls_celltab-style = cl_gui_alv_grid=>mc_style_disabled.
APPEND ls_celltab TO OUTPUT-STYLE.
ENDIF.
append OUTPUT.
I have tried adding MC_STYLE_F4_NO to field LS_CELLTAB-STYLE2 but this does not do both actions atthe same time.
Can anyone suggest what I might be doing wrong or an alternative way around this?
Many thanks
Regards
Larissa

As I have explained, I have fields that are editable AND are F4 enabled. What I want is for certain rows of the ALV that I do not want any procesing to occur to make all fields in that row not available for input AND not f4 enabled. I read a lock using a lock object. If the entry in my ALV matches the key locked in the lock object, I want that line to be in display mode only in the ALV with no F4 help being able to be called. It happens on the grid frontend when I press enter and have checked if any of my entries in my ALV are already locked by another user. The code is too long to post here. I can disbale the editable fields using MC_STYLE_DISABLED as described above but then the little drop down to enable F4 input is still visible against the field.
I have got round it by calling the f4 in event HANDLE_ON_F4 to not go via the search help and set er_event_data->m_event_handled = c_yes so that the F4 hit list does not appear, but I want to get rid of the drop down marker in that field in that instance.
Hope this is a little clearer now.

Disable input in certain cells of ALV

Hi All,
This probably has been posted before, but i can't find the answer to my question, I have an ALV table that requires certain cells to be disabled and enabled based on the value.
Can anyone guide me on how do i go about solving this? also if you have good sites/guide step by step on cell variant. please let me know.
Help is very much appreciated.
Thank you,
Vinod

You need to use Cell variant.
Refer the Program: SALV_WD_TEST_TABLE_CV

I have tried all the steps you listed in your FAQ sextion on enabling and disabling cookies but I am still getting the error message "cookies not enabled" on certain websites. Now what do I do?

I have tried every step you have listed in your FAQ section for enabling and disabling cookies but I am still getting error messages "cookies not enabled" on certain websites? Why is this and what do I need to do to fix this?

I have STILL NOT received an answer to my question as of this date. I am VERY disappointed in Firefox support.

Enable / disable combo box in datagrid cell

I have a datagrid with 8 columns 2 check boxes a text box and
5 combo boxes. I am trying to disable the combo boxes if the first
check box is not checked. So far I am able to disable the entire
column with the combo box in it, but what i am trying to achieve is
if the check box is false then the 5 combo boxes are to be
disabled.
So what I am asking in a nutshell is is there a way to enable
or disable particular cells in a datagrid ?
Example
of what I have already done
Any suggestions will be gratefully received.

I put the following code in that I took from samples:
Bindable]public var test:ArrayCollection;
private
function init():void
test =
new ArrayCollection([{label:"High", data:"high"},{label:
"Medium", data:"medium"},{label:
"Low", data:"low"}])
Then in the mxml:
<mx:DataGridColumn
headerText="From Fiscal Period">
<mx:itemRenderer>
<mx:Component>
<mx:ComboBox dataProvider="{test}">
</mx:ComboBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
I still get the same error: 1120: Access of undefined property test.

Enabling/Disabling PDF in Browser Option (Acrobat XI)

Firstly, know that yes I understand that this setting is no longer found in and handled by Acrobat XI and that to enable or disable PDF in browser setting you enable/disable the add-on in IE (or other browser).
In the hopes of making it more straightforward and convenient for users to toggle this setting, one option is being explored to create a custom Javascript action in Acrobat to write to the user registry to turn this on/off.
Is this feasible? Can Acrobat JavaScript actions read and write to the user's registry? As we have a collection of users that need to regularly toggle this setting (for reasons I won't go into here), it would be ideal to have an easy and straightforward means to change this setting. One possibility might be a custom Acrobat JavaScript action.
Thoughts, suggestions, ideas?
Thank you

Thank you. Forgive me but I want to make absolutely certain...in no way can a custom Acrobat JavaScript action change the user's registry. Is this correct? A pointer to official documentation stating such would be excellent. I have to convince someone not easily convinced

Hide/show or enable/disable report column

Hi,
I m using Oracle Apex4.0
I m having an interactive report which has a cloumn with Link provided to it.
I want to enable/disable the linked cloumn for certain records or else the link column can ba hidden/shown for certain records.
How can it be done?

Hi,
Did you look at the Denes example ? It looks as good solution for you.
Is your report in format like this ?
col_1 col_2 col_link
col_1 - column1
col_2 - column2
col_lnk - column with link
in the link there is some redirection to detail page where you can provide update ?
the link should contains record ID. correct ?
The only possibility in your case is Denes or some other simple solution. (case solution)
It should be good if you reproduce it on apex.oracle.com
We can provide more help to you in there.
Regards

Updater fails 9.1.1 to 9.1.2 - msg "re-enable disabled components"

Adobe reader 9.1.1 won't update itself via updates, nor will the stand alone updater work.
The "re-enable disabled components" message referred to with other products pops up.
I've deleted the app. Deleted all pref and lib/app support files. Reinstalled, and hit the same wall.
The computer is PPC running 10.5.7.
The HD is formatted w/ a case-sensitive journaled HFS.

Michael:
Thanks for your speedy reply.
Adobe Reader has worked atop case sensitive file systems for me for some time. I began using them in 10.4 Tiger, though they were introduced as an option going back to 10.3 Panther, which was released to the public 10/2003, and developers like Adobe before that.
If the file system is not supported then it should be clearly, and prominently noted on the download page, and perhaps a warning in the installer (if the installer can't itself test for the presence/type of file system and put up some dialog box warning of pending difficulties).
While I don't use/have no need for the CS, I'm aware of the issues Adobe had w/ the CS suite and case sensitivity (it was just reported in the mac news) but I don't ever recollect seeing that Reader was affected. Certainly finding out that this is the case by doing google searching, troubleshooting, and help forums takes a distant rear seat to getting warned up front.
Just to make sure, I went to the download page (no warning), went to system requirements (no warning), and opened up the files that are downloaded (and again, no warning in the installers).
As a layperson I have trouble imagining that the coding/development of a PDF reader would be inconsistent to the point that it breaks down trying to point to its own components..but that is probably an oversimplification.
Hope that it is resolved, and that until then appropriate warnings are offered to end users.
Thanks again for your time and interest.

Is it possible to programatically enable/disable a schedule?

Hi,
I'm looking for a way to start and stop an existing schedule based on certain criteria.
Is it possible to enable/disable a schedule programatically, from within an Action block? Calling an HTTP URL for example?
Thanks.

Hi,
One solution would be using the Illuminator service for this:
First execute the Scheduler service with list mode (using XML query or HTTP Post action) as :
/XMII/Illuminator?service=Scheduler&mode=List
This will give you the list of the available scheduler configurations in the system along with the corresponding Job ID. Use XPath in BLS to retrieve the JobID from the list by the Scheduler Config name.
Next execute the Scheduler service with Disable mode passing the JobID retrieved from :
/XMII/Illuminator?service=Scheduler&mode=Enable&ID=<JobID>
This will disable that particular scheduled job. To enable it use the same service with Enable mode:
/XMII/Illuminator?service=Scheduler&mode=Disable&ID=<JobID>
Hope this helps.
Thanks,
Dipankar

Disabling a cell or a row in a matrix

1.is there a way to disable a cell in a matrix?
2.is there a way to disable a row in a matrix?
3.is there a fast way to disable all the controls on a form as a result of a checkbox change?
rgds
Hagai

1) Yes
<b>Code (C#):</b>
// Get the item properties of a cell
SAPbouiCOM.Item oItem = (SAPbouiCOM.Item)oMatrix.Columns.Item("LOC_CODE").Cells.Item(1);
// Disable the cell
oItem.Enabled = false;
<i>Notes:
- oMatrix is my matrix object
- LOC_CODE is a column name in my matrix
</i>
2) Probatly... It can be done for each column as I described above, but there could be a better alternative?
3) I guess not, you should disable all controls one by one

Multipage Crashes if enabling/disabling

Hi folks
This is the first time using this control and I have some real issues with it after initially thinking 'this is a cool control', no more frames and tabstrips!! However, for no apparent reason, just enabling or disabling the multipage as the form loads or
disabling certain controls within it in normal use causes Excel to go 100% processor, 'Not Responding' and you have to end the process. If I click a tab and all the controls are disabled within it, I can get the same problem. I have
even stepped through the code where it disables a control or the multipage and it crashes after executing the line!!
The form is very straightforward, 4 radio buttons, about a dozen text boxes spread between three pages connecting to an Access DB after doing some simple updates to a spreadsheet. I have tried the same spreadsheet in 2003, 2007, 2010 and 2013
on different machines and all exhibit the same problem. Just removing a control from the form or disabling the multipage after the form is displayed seemed to solve the problem until it reared it ugly head again when I disabled all the controls on one
tab and then selected the tab after the form was displayed...crash again. Locking the controls instead of disabling them...all works fine!!!!
I have only found one similar post to this and the 'clean-up tools' link is broken. Is there anything I can do with this to identify what the problem is? Obviously a nasty exception under the hood.

Eventually I found out what causes this and similar problems! When you first use an ActiveX control it caches a version of it to speed up loads the next time. If for some reason, most recently, a security update causes the underlying DLL interface
to change, the interface can end up being incompatible and crashes the workbook. You can get similar problems when you move a workbook written in 32-bit to 64-bit. On some systems you will not see any problems because a recompile would normally
refresh the caches but various reasons can prevent them from being updated.

Apple script to enable/disable dark menu bar and dock when sunsets/sunrises

Greetings,
Regarding the new dark menu bar and dock function in Yosemite. Would it be possible to write a script that would enable this function at a certain time say sunset and to disable it at another time say sunrise?
If so, is there anybody who could possibly help me write such a script or atlas point me in the right direction please?
Many thanks in advance
G_D

Although you can set or remove the Dark interface style with defaults write syntax, the reset back to default (non-dark) interface will require a log-out/log-in cycle to entirely remove the Dark style. Toggling this style on and off in the System Preferences > General panel does not require the preceding log-out disruption. Unfortunately, other than possible GUI scripting, the Apple Script dictionary in Yosemite is very limited with respect to System Preferences access, and enabling/disabling the dark interface style.

Enable/disable fields in Workspace form

Okay here is my scenario. I need to disable some fields on a form depending on which user logs onto workspace to open the same form.
1. User1 logs onto workspace and opens leave request form, fields at the top of the form are enabled for the user to fill out, bottom fields which are for leave request administrator to fill out are disabled but visible.
2. User1 fills out top portion of leave request form and completes form. Workflow sends form to leave request administrators "To do" list in Workspace.
3. Administrator opens up submitted form in Workspace and sees User1's filled out data on the form and the bottom fields are now enabled for administrator to approve or dissaprove. Bottom fields only include two check boxes, two text fields and one date field.
Now how is this done? I am sure their maybe scripting involved? if so what is it and at what events in the form? Is this whole process done in the form or through Admin UI or Workebench as well? Please help!!!!!!!!!

Hi Rahat,
You can use the same form and enable/disable some fields according to the user's role with only little scripting. Review the steps the below:
1-First place a hidden field ("user_role") in your form
2-Insert a script object into your form onder "Variables" in object hierarchy and write a script for enabling/disabling the fields (regarding the value of "user_role")
3-On the initialize and change events of the "user_role" call your script object
4-On your process design, put a SetValue service before User tasks. In the asssignment you should set the desired user_role to the form, so that the script is triggered in your form and the fields are enabled/desiabled
Fro further needs on your form or process design you can contact us from: http://www.kgc.com.tr/company_Contact.html
