How to handle shortcut key options in LabVIEW

Hi,
I want to handle the ctrl+c option for a string control in labview. I just want to prevent the user from pressing the ctrl+c button for copying. is it possible to handle that inEvent Structure?
Thanks
Alagar

Ben,
removing the entry Copy from the context menu is not sufficient. In order to disable the control to copy the current active selection, you have to disable <ctrl + c> as shortcut for copying data in the complete LabVIEW environment. You have to open the Tools >> Options, switch to Menu Shortcuts and browse to Edit >> Copy. Switch the shortcut to something else than <ctrl + c>. This will disable the copy function for the shortcut <ctrl + c> (it will occur with the new shortcut of course!)
Drawback:
a) You remove the ability to use <ctrl + c> from the whole LabVIEW environment. So also in edit mode of VIs....
b) When making a selection and then pressing <ctrl + c>, it will replace the selection with a simple 'c'. Most often, this is not intended.
So all in all, i would definetly NOT recommend anyone to alter the shortcuts for common functions defined by the OS (<ctrl + c> for Copy, <ctrl + n> for New Document, .... )
hope this helps,
Norbert

How to set Shortcut keys for button in Apex

Hi
Could anyone help me on how to set shortcut keys for buttons in Apex.
I need to use say ALT + S to submit the page.
The following thread pertaining to HTML DB refered to use ACCESS key. but that couldnt work in my case.
Re: operation of the app. with the keyboard
Any pointers on achieving this would be helpful.
Thanks
Vijay

Hi Vijay,
I’m afraid you must do it using javascript key listener. You can’t use action() on template based buttons because they are actually not HTML buttons but images with hyperlink.
Key listener checks which key has been pressed down and invoke some JS function. For example, write this code in page header:
<script>
document.onkeydown=keyCheck;
function keyCheck(e){
     var KeyId = (window.event) ? event.keyCode : e.keyCode;
     switch(KeyId){
          case 113:
               doSubmit('SAVE');
               break;
          case 118:
               alert('Hello');
               break;
</script>
This script will submit page with request 'SAVE' if you press F2 or will show alert message if you press F7. Modify it to your issue.

How can configure shortcuts key like in CFstudio 5

how can configure shortcuts key for CF tags (e.g. alt + o for
cfoutput) like in CFstudio 5? With DW 8 it seems not possible
unless you write a snippet of the cf tag which is time consuming.
There must be a smarter way. Any feedbacks? Thanks

Don't have DW8 in front of me (am at work, still using
MX2004), but look in the edit menu for Keyboard shortcuts. It will
open up a dialog box where you can re-assign

You can't change them. Some stuff is simply hard-wired.

How to use shortcut keys on wireless keyboard with ipad

i just purchased an ipad 4 with a wireless keyboard and do not know how to use the function keys on the wireless keyboard to access the homescreen, scroll up and down, etc. please help with anything i need to turn on/off or download . thanks

If you have more than one keyboard active, you may be using a different one than you want. Use the "globe" key to make sure your virtual keyboard is set to Japanese Romaji or Japanese Kana. Which one do you use?
On the hardware keyboard, use apple/command plus space to switch between different keyboard layouts which may be active.

How to get NI veristand option in LabVIEW tools menu

HI All
I have developed a code in LabVIEW for which I want to develop Veristand model.
but for creating the model , the procedure which i followed on this forum is from LabVIEW tools go to NI Veristand and then create the model.
BUt in my LV2013 and 2012 also , I am not getting NI veristand option in tools.
I have NI veristand 2011. Do i need to select any option while installation?
I have selected LV model support also while installing.
Please help.

You need LabVIEW 2011 to build lvmodels for VeriStand 2011. This goes for all LabVIEW plugins.
After you install LV 2011, you can re-run the veristand 2011 installer and select the model support option I believe I get the menu item you need.

How to handle 'ENTER' Key on ALV Editable Grid on sub screen (Tabstrips)

Hello Experts ,
I have 2 questions with ALV Editable grid;
please help me if you have answers.
I created ALV grid on one of sub screens on a Tab Strip,
As soon as user types one of the columns of the ALV grid and press u2018ENTERu2019 key, it has to return corresponding details for that line.
I tried to implement this logic in ALV grid event u2018handle_data_changedu2019, but ALV internal table is not getting populated with new entry entered in the grid. but u2018double_clicku2019 event working my purpose, but user might need enter key.
and I thought I would do implement that logic in PAI event of the sub screen, u2018ENTERu2019 key not getting trigger on PAI event of the screen until cursor is on grid.
Another question 2: How do I control and not to be deleted a line on the grid (based on validation), where do I validate and by pass the delete function for a particular line, or suggest me to gray out only one line on the grid .
I would like to have delete function to work as it is ,except for some validations..
Can I implement using PAI event of the sub screen or any by ALV event.
Please suggest me..
Edited by: Ravindranath Arusam on May 13, 2010 2:42 PM

In DATA_CHANGED event, you will get the modified row into the attribute MP_MOD_ROWS of the impoerting object ER_DATA_CHANGED. Since this MP_MOD_ROWS is the Object reference to Data, you need to have the field symbol to get the value.
FIELD-SYMBOLS: <lft_mod_output> TYPE t_t_output.
ASSIGN er_data_changed->mp_mod_rows->* TO <lft_mod_output>.
You can get the Value of the Cell by using the method GET_CELL_VALUE of the same ER_DATA_CHANGED object and use the method MODIFY_CELL To update the value back to ALV.
To Restrict the row deletion:
When the row is deleted it is being added to Attribute mt_deleted_rows of the object ER_DATA_CHANGED. You can put the data back to the table in the DATA_CHANGE_FINISHED event. Visit this post http://help-abap.blogspot.com/2008/10/alv-disable-delete-key-on-keyboard-in.html for more information.

How to disable shortcut keys not listed in the keyboard shortcuts system

Hi all
As a Graphic Designer I find the shortcut Shift+F12 amazingly irritating when using QuarkXpress, as this is the key command for editing the colours list. For those of you who don't know this shortcut works exactly the same as F12 (Hide/Show dashboard but in slow motion.
You may be supprised that I find this of somewhat limited usefulness.
Can anybody help?
Ta

Hi supertottenham
The Shift key is slo-mo for several functions so I doubt if it can be disabled.
However if Dashboard is not one of your priorities there is an app called TinkerTool which enables alterations to several of the built in apps including Dashboard which it stops appearing completely including Shift+F12
It is a freeware download from http://www.bresink.de/
Hope this is of some use

I have a small issue in terms of cleaning up the data while loading into BI..
Based on some specific fields I am sorting and deleting adjacent duplicates from source_package using start routine then its working fine for most of the cases but not working for some records
when I observed that It was due to the reason that those records fall into different data pockets so start routine is not able to identify the duplicates.....how can we handle this ..
Any idea Pls???

How to handle radio /checkbox options

If you have a report like so
select HTMLDB_ITEM.RADIOGROUP(1,accid,'keep') "Accept",HTMLDB_ITEM.RADIOGROUP(1,accid,'delete') "Delete" ,accid,userid,username,authfails,clientid,tncdate,docsource,lastlogin,usertype,dateadded,recert from GFMIS.AUTOBAHNDIRECTACCOUNTS where recert = '0'
Which would diplay two radio buttons one with keep and one with delete. When run run this through a process like
FOR i in 1..HTMLDB_APPLICATION.G_F01.COUNT LOOP
UPDATE GFMIS.AUTOBAHNDIRECTACCOUNTS SET recert = '1', RECERTBY = :APP_USER, RECERT_DATE = SYSDATE, RECERT_ACTION = 'radiobutton' WHERE ACCID = HTMLDB_APPLICATION.G_F01(i);
END LOOP;
How do i say if radiobutton = 'keep then RECERT_ACTION = 'what ever radio button was selected'

Hi Kiranmai,
You can capture the event of the radio button in the following way in oninputprocessing.
DATA: event             TYPE REF TO if_htmlb_data,
               radioButton_event TYPE REF TO CL_HTMLB_EVENT_RADIOBUTTON.
         event = cl_htmlb_manager=>get_event( request ).
         IF event IS NOT INITIAL AND event->event_name = htmlb_events=>radiobutton.
           radioButton_event ?= event.
           ENDIF.
you can get the attributes of clicked radio button in
event->event_class
event->event_id.
event->event_name
event->event_type
event->event_server_name
In layout define the radio button as
<htmlb:radioButtonGroup   id          = "test_id">
        <htmlb:radioButton      id          = "id_red"   text = "Red"               onClick="myClick" />
        <htmlb:radioButton      id          = "id_blue" text = "Blue"          onClientClick="alert('blue clicked')"/>
        <htmlb:radioButton      id          = "id_green" text = "Green"      onClick="myClick" onClientClick="alert('green clicked')"/>
      </htmlb:radioButtonGroup>
Hope this will solve your problem.

How to handle multiple key press in numeric keys

I have used the code from eta . Code is somethg like tis
lastKeyPress = System.currentTimeMillis();
protected void keyPressed(int keyCode){
          boolean keyRepeated = false;
          if(System.currentTimeMillis() - lastKeyPress < 1000 &&
     lastKey == keyCode) {
          keyRepeated = true;
          lastKey = keyCode;
     lastKeyPress = System.currentTimeMillis();
switch(keyCode) {
          case KEY_NUM0 :
          case KEY_NUM1 :
