I am having trouble getting following code to work from the other month for altering a control to read-only.

The code is in a subroutine as below. I pass the Ctrlentid. I checked the STYLE property before and after the send_message, but it doesn' t change.

What am I doing wrong?

TIA

Glen.

Previous Code:

$INSERT LOGICAL

Equ WM_USER$ To 1024

Equ WM_SETREADONLY$ To WM_USER$ + 31

hwndEdit=Get_Property( CtrlEntID, "HANDLE" )

Call SendMessage( hwndEdit, WM_SETREADONLY$, TRUE$, 0 )

Hi Glen,

This message only applies to EDIT class controls ( Edit Lines and Edit Boxes in OI-speak ), so is this what you are trying to use this on?

Can't say as I've ever had any problems with this before…

Thanks Carl,

The controls I'm trying to make read-only are EDITLINE/EDITBOX type controls! The style before and after for EDITLINE is 0x50000080 running previous code.

Do I need to change the STYLE manually?

Regards,

Glen.

Glen,

The code is 100% correct. It works all the time for me.

(Or 99% correct, because (according to Carl) WM_SETREADONLY$ should be EM_SETREADONLY$, but what's in a name?)

The only possible error I can think of is that your CtrlEntId is wrong.

(Or there was one other thing I had a problem with once. Is your edit box bound to a symbolic field? Then the form compilation logic automatically makes it disabled. So you might have to call set_property(…, 'ENABLED', TRUE$) right before you make the edit box read-only (quoting Gene). But I don't know if this really affects the STYLE property.)

Hi Glen,

You shouldn't need to change the STYLE at all…check Oystein's response, is it a symbolic?

Carl

Thanks Carl and Oystein.

When is a SendMessage not a SendMessage? When its a Send_Message! Sometimes I amaze myself.

Apols,

Glen.

Glen,

I at least don't need any apologies. I'll fight for the right to make blunders in public. I don't know about Carl, though.
