Problems saving and loading RichEdit file after resizing image.

[Jemboy]

Hi,

For an internal project I want to write internal script to mail some special request to an external party.
To make it a little bit universal I decided that the user should be able to write or edit the e-mail signature.
Because I wanted to put a logo into the e-mail, I decided to use RichEdit.

I I found the following code by  @UEZ and adapted it a little to save and load.
When I start the script and edit the text only, I can save and load the signature.rtf.
However the moment I resize one of the images (with the mouse), the script wil only save the edited image.

Somehow resizing an image deletes the other content of the RichEdit object.

Does anyone know a solution for me?

P.s. you need to delete signature.rtf to reset the file.

changing to:

Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE, $idBtnExit
                _GUICtrlRichEdit_SetSel($hRichEdit, 0, -1, True)    ;this line avoid's the problem
                _GUICtrlRichEdit_StreamToFile($hRichEdit, @ScriptDir & "\signature.rtf")
                _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
                GUIDelete()
                Exit
        EndSwitch

@AutoBert your addidtion was spot on. All RichEdit changes are now saved properly. Thanks!!!😀

_GUICtrlRichEdit_SetSel($hRichEdit, 0, -1, True)    ;this line avoid's the problem

2. (and better solution?)

Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE, $idBtnExit
                _GUICtrlRichEdit_Deselect($hRichEdit) ;needed unless in case a image is selected only the image will be safed  
                _GUICtrlRichEdit_StreamToFile($hRichEdit, @ScriptDir & "\signature.rtf")
                _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
                GUIDelete()
                Exit
        EndSwitch
