How to set control text
Hello,

New to NSIS... I'm trying to set control text to "AAA". I'm doing this in the following way:

...

!include LogicLib.nsh
!include nsDialogs.nsh

!macro __SetText CONTROL VAR
System::Call user32::SetWindowText(i.${CONTROL}, t.'AAA')
!macroend

!define SetText `!insertmacro __SetText`

...

(In a callback:)

${SetText} $Ctl "BBB"

But it doesn't work. I tried to change prefixes in SetWindowText (i ... t), but no success. See the attachment.

Any idea?

Thanks.

I have tried to make it:

!macro __SetText CONTROL VARIABLE

 !ifndef __SetTextVars

   !define __SetTextVars

   Var /GLOBAL __SetTextVar1

   Var /GLOBAL __SetTextVar2

  !endif

 StrCpy $__SetTextVar1 `${VARIABLE}`

 StrCpy $__SetTextVar2 `${CONTROL}`

 messagebox mb_ok `$__SetTextVar1 $__SetTextVar2`

 System::Call user32::SetWindowText(i$__SetTextVar1, t$__SetTextVar2)

!macroend

>!define SetText `!insertmacro __SetText`

...and call:

StrCpy $0 'AAA'
${SetText} $EDIT $0

But it doesn't work. I know, where is problem - because I don't understand that i., t., i, t tricks

!macro __SetText CONTROL TEXT
System::Call `user32::SetWindowText(i${CONTROL}, t${TEXT})`
!macroend
!define SetText `!insertmacro __SetText`

... It also doesn't work.

But I found a solution elsewhere:

SendMessage $Ctl ${WM_SETTEXT} 0 STR:$Text

Thanks for replies.

Sorry, would need to ensure that the text is surrounded by quotes:
System::Call `user32::SetWindowText(i${CONTROL}, t"${TEXT}")`

WM_SETTEXT with SendMessage will work as well.
