But I'm still unsure whether this is really what you are wanting to achieve. Why can't you use a single editbox and simply update the text it contains?
Richard.


That is exactly what I am trying to do. The box is intended to show the current status of a process, and all that is required is to update the message displayed in the box from time to time. How do I do this?

You will probably want to use a read-only edit box, or perhaps a simple static control, so the user cannot modify the contents. Other options may be to display the information in the title bar or a status bar.

Quote:

That is the most basic of all operations on a dialogue box item, and indeed is the first to be described in the Initialising the contents of a dialogue box section of the BB4W Help docs:

http://www.bbcbasic.co.uk/bbcwin/manual/bbcwing.html#initdialog

It says: "To change the text associated with a dialogue box item (which may for example be the contents of an edit box or a label for a check box) you can use the SetDlgItemText API call":

Code:
      SYS "SetDlgItemText", !dlg%, id%, text$

Of course had GUILIB been developed it would have included a BASIC wrapper function for this call.

Richard.

Another one bites the dust.

It's easy when you know how (and when you remember to read the right documentation)!

Thanks Richard
