Writing Text to MUI Dialog Control

Hello,
I have a requirement to preset the value for a text control, when the parent custom dialog box is displayed.

Here's the code for the leave function, associated with the dialog box:-

Function LeaveDialogue
; Write the value to text box
!insertmacro MUI_INSTALLOPTIONS_WRITE "${DIALOGUE_INI}" "Field 1" "State" "Hello After"

; Read the text box value
!insertmacro MUI_INSTALLOPTIONS_READ $0 "${DIALOGUE_INI}" "Field 1" "State"

; Display the text box value, recently read
MessageBox MB_OK $0

FunctionEnd

When the value is read, it is the new value ("Hello After"), but the text box doesn't refresh the value on the screen.

Any solutions?

You need to set the text with SendMessage and ${WM_SETTEXT}
