Disable Copy/Paste In SingleLineEdit in PowerBuilder

Published on 24 August 18

Stop Copy/Paste Into Single Line Edit

You might have Encountered the scenarios where we are supposed to stop copy/pasting from RightMouse Button / SHIFT + Insert / Cntrl + V to the Single Line Edit. Use the below technique to accomplish the same

/* Create a function f_dissable_copy_paste or a window function of_disable_copy_paste( ) with return type (None) and write the below code in that. I am using window function in this case.*/

string ls_str

ls_str = clipboard()

ls_str = ""

clipboard(ls_str)

/* To Disable right click write below code in RButtonDown of SLE*/

MessageBox("Info","Right Click Disabled,Please enter the values manually")

of_disable_copy_paste( )

return 1

/* To Disable the Cntrl+V and Shift+Insert options, the moment the user press Cntrl/Shift make the clipboard data to blank which means nothing will be there in clipboard to copy. Simple, right? But how to achieve this ?*/

/* Write one user event ue_disable_copy_paste for SLE and select the event ID as pbm_keydown . Write the below code in that */

IF Key = KeyControl! or Key=KeyShift! THEN of_disable_copy_paste( )

That's It!!!!!!!!!!!

You may use a userobject of SLE type and reuse the code further if you are using SLE multiple times :)

Hope you enjoy this!

Note:

Make sure - if you want to use control and shift the focus should not be on SLE
