delete in edit menu, select all text

[Brian Heibert]

How do I do the delete function in the edit menu?
Sometimes called Delete other times called Clear?

Also how do I select all text in my edit field

Brian,
In the other example I gave you , with the Select/Unselect text, at:

http://www.garybeene.com/power/code/gbsnippets_gbs_00139.htm

If you want to remove the text in an edit control, then all you need is to use this line for the response code for one of the buttons.

Control Set Text hDlg, %ID_Text, ""

[Brian Heibert]

I tried to use this
CONTROL SET TEXT hDlg, %IDM_EDIT_DELETE, ""

However it isn't working it doesn't delete the text in the edit field

Really Brian, showing your full code, preferably in compilable form would get you a lot more help that wouldn't leave you asking so many questions. Reading the manual and checking the files in the Examples or Samples folder that came with your compiler would save you time.
Because some of your questions are to some quite elementary, we aren't sure that you are asking the right question.
In this latest question of yours, an ID with %IDM_etc is usually a Menu ID and as such "CONTROL SET TEXT" does not apply to it.

There is a very good Menu example in the Help file, just click on M from the home page of the HELP, select a MENU item and at the bottom of it, it will show "EXAMPLE See Menu Example".

The EM_SETSEL message allows you to set the selection text in an edit control; the EM_REPLACESEL message allows you replace that selection with anything, or with nothing (delete it).

Windows provides messages for easily duplicating functionality in an edit field context menu:

MSDN: WM_UNDO
MSDN: WM_CUT
MSDN: WM_COPY
MSDN: WM_PASTE
MSDN: WM_CLEAR (delete)
MSDN: EM_SETSEL

EM_SETSEL can be used in this form to duplicate Select All functionality:

SendMessage hWnd, %EM_SETSEL, 0, -1

or

CONTROL SEND hDlg, CtrlID, %EM_SETSEL, 0, -1

[Michael Mattias]

....OR (for those of us who cannot remember which parameters are used with which messages.. or how to spell all those messages )......

#IF %DEF(%USING_DDT)
   MACRO Edit_SelectAll (hWnd, idctrl) = CONTROL SEND hWwd, idctrl, %EM_SETSEL, 0, -1&
#ELSE
  MACRO Edit_SelectAll (hWnd, idctrl) = SendDlgItemMessage hWnd, idctrl, %EM_SETSEL, 0, -1&
#ENDIF


....
CALLBACK FUNCTION ....
       
        Edit_Selectall (CB.HNDL, %ID_MY_TEXTBOX)

delete didn't work

I tried to do this to do delete

CASE %IDM_EDIT_DELETE
' Control Set Text hDlg, %IDM_EDIT_DELETE, ""
CONTROL SEND hDlg,%IDC_USERENTRY, %EM_SETSEL, 0, -1

But nothing happened no deletion

What next?

>What next?

What's next is learning how much and how to post the code which is giving you trouble.

[Fred Buffington]

How about

LOCAL Clearit$=""
CONTROL SET TEXT hDlg,Control_ID%,Clearit$

where hDlg is the dialog handle and Control_ID% is the handle of the control within the dialog.

This will work for textbox and Static controls (Label).

[Rodney Hicks]

Try it this way:

CASE %IDM_EDIT_DELETE
   ' Control Set Text hDlg, %IDM_EDIT_DELETE, ""   
   CONTROL SET TEXT CB.HNDL, %IDC_USERENTRY, ""
   CONTROL REDRAW CB.HNDL, %IDC_USERENTRY

The REDRAW forces the change now, rather than letting it wait in the queue.
Notice the use of the CB.HNDL instead of hDlg in the CALLBACK FUNCTION.

He has posted the code in one of the many other forum threads dealing with his issues. An epiphany is in order, though.

IMO one should not ask others to "search" - and in this case, "guess which one" as the first step in helping you.

Besides, if this line is not working, it's not the same code, is it? And I do believe we've all seen one or two times A "problem line" was not THE REAL "problem line."

Michael, I am not and was not expecting you to experience the epiphany!
I concur fully with you.
