Hello, please check the attached sample. It works fine on the current release.
Regards, Fred

Thanks !! Your sample works fine.

(defun c:Test(/ c:Test/Dialog1#OnInitialize)

    (defun c:Test/Dialog1#OnInitialize (/)
(dcl-Control-SetBackColor Test/Dialog1 200)
(dcl-Control-SetBackColor Test/Dialog1/Rechteck 200) => it works !!
      ); c:Test/Dialog1#OnInitialize

      (dcl-Control-SetBackColor Test/Dialog1/Rechteck 200) =>  it does not work !!
)

But why it does not works outside (defun c:Test/Dialog1#OnInitialize (/) ..) ??

Sorry , I am a beginner in lisp and sorry for my bad english !

Hi, please have a look at the samples of OpenDCL. You can only set control properties within the form's or control's events within modal forms.
Of course you can set control properties outside the events if you use modeless forms or palettes.
