Insert Text to Line Number in Edit Control - ?

[atomman]

Need to insert text at a specific line number (already existing) in an edit control, something like _GUICtrlEdit_InsertText, except that does character positioning.

I know how to do it with caret position, but that's not reliable in my case.

Might look at _GUICtrlEdit_LineIndex in conjunction with _GUICtrlEdit_InsertText

[atomman]

i looked at that before, but didn't understand how to use it.

what is a "character index"?

Return Value -- Success: the character index of the line specified in the $iIndex parameter

That's from the manual and i read about the functions used in that example and played with the script. Still, i don't understand how to use '_GUICtrlEdit_GetLineCount' and '_GUICtrlEdit_InsertText' to insert text to a predetermined line number in an edit control. And i'm not seeing how 'Random' can be used to generate the current line number from the caret position. I can convert 'WinGetCaretPos' to a line number, but now i need to write to that line number.

I've been toying with different methods of doing this for days and days and none are reliable/work. I'm so close to being done with this script but being able to simply write to a line number like "_FileWriteToLine" does is driving me

Your looking to hard at it, it's simple, the 'Random' and _GUICtrlEdit_GetLineCount represent the line you want to insert text in, I have no idea what line you want to insert at.

For all intents and purposes you only really need to look at

_GUICtrlEdit_InsertText($hEdit, "MY INSERTED TEXT", _GUICtrlEdit_LineIndex ($hEdit, 'your line number goes here'))

[atomman]

It works! And i can now see why it works. Thank you Gary!

I think a UDF would be a good idea here -- _EditWriteToLine -- but that's over my head.

[atomman]

I spoke too soon...

I still need to find a way to insert text at an edit control line number.

Right now i'm converting WinGetCaretpos() to a line number then using something like this, inside a while loop, to write:

If WinActive($Form1) Then
    $Caret = WinGetCaretPos()
    $Line = (($Caret[1] - 3) / 13)

  Case $Button1
    _GUICtrlEdit_InsertText($Edit1, $Text1 & @CRLF & $Text2 & @CRLF & @CRLF, _GUICtrlEdit_LineIndex($Edit_TextEditor, $Line))

It seems very finicky... works much of the time, then fails, and it's now frustrating the daylights out of me.

[atomman]

trying this once again and it seems to be working.

$Line = (ControlCommand($Win_SBE, "", $Edit_TextEditor, "GetCurrentLine") -1)

[atomman]

nothing works because of the behavior of edit controls -- everything gets selected when you click, or there just isn't a caret, etc..

is there not a simple way of writing to a specified line number in an edit that works?

[therks]

I think you have to stop saying "specified".

To me, specified means you are giving it a specific number, which Gary has given you code for (which works in my tests): _GUICtrlEdit_InsertText($hEdit, "MY INSERTED TEXT" & @CRLF, _GUICtrlEdit_LineIndex ($hEdit, LINENUMBER))

It seems to me that the real problem you're having is retrieving the current line number.

[atomman]

Yeah, for the most part i think you're right, but i had problems with both. The biggest problem is everything getting selected in an edit control when it's focused.

For now i *think* i have it working, but the nature of edit controls (selecting everything) makes it annoying. I asked in another post if there was a way to prevent this and didn't get an answer. If you can help me out, i'd certainly appreciate it.

Would look at using _GUICtrlEdit_SetSel and set the start and end to the same position where you want to insert the text

Or instead of using the built-in edit control you could use the _GUICtrlEdit_Create, doesn't select all when it gets focus.

[atomman]

the latter would be the ticket. was close to trying _GUICtrlEdit_Create before, but i didn't see why i'd need it. now i do!

thx
