Hi,

I am using OpenEdge 10.2B and download ocx button. it called MyHover.ocx. This ocx is already work when using AppBuilder.

But i failed to create MyHover.ocx using Procedure Editor ( Progress 4GL) as i want to create it dynamically.
Is anyone can help me ? I am very appriciated if can give me an example program.

Thanks in advance.

I just can tell you why it does not work: The integration with OCX is static in that the AppBuilder creates a control frame when you drop an OCX onto a Progress frame as an interface to the OCX. Furthermore it automatically creates a file with the same name as the 4GL program but with an extension of wrx. That are the steps that you are missing and I don't know whether you could achieve them dynamically at run time but I doubt it.

Instead you would need OLE automation integration - which, IMHO of course, might not make that much sense for a user interface widget.

Maybe somebody else knows how you can work around this.

Hi RealHeavyDude,
Thanks for your reply.

Hi Cringer,
These are the answer:
1. Progress OpenEdge Studio 10.2B No Service Pack
2. Windows XP SP 3
3. Just now i succeed to create 2 button MyHover dynamically.

The Steps as follows:
A. Create .wrx file.
1. Using Appbuilder, Create Window
2. Put the MyHover ocx button
3. Save file . ie. c-win.w

B. Create program to create Myhover ocx button dynamically.
The Simple Program as follow:
================================================================================================
DEFINE VARIABLE CtrlFrame AS WIDGET-HANDLE NO-UNDO.
DEFINE VARIABLE chCtrlFrame AS COMPONENT-HANDLE NO-UNDO.
DEFINE VARIABLE UIB_S AS LOGICAL NO-UNDO.
DEFINE VARIABLE OCXFile AS CHARACTER NO-UNDO.
DEFINE VARIABLE CtrlFrame-2 AS WIDGET-HANDLE NO-UNDO.
DEFINE VARIABLE chCtrlFrame-2 AS COMPONENT-HANDLE NO-UNDO.




OCXFile = SEARCH( "c-win.wrx":U ).

DEFINE FRAME frame01
WITH 1 DOWN NO-BOX KEEP-TAB-ORDER OVERLAY
SIDE-LABELS NO-UNDERLINE THREE-D
AT COL 1 ROW 1
SIZE 80 BY 16 WIDGET-ID 100.


CREATE CONTROL-FRAME CtrlFrame ASSIGN
FRAME = FRAME FRAME01:HANDLE
ROW = 2
COLUMN = 14
HEIGHT = 1
WIDTH = 15
HIDDEN = no
SENSITIVE = yes.


CREATE CONTROL-FRAME CtrlFrame-2 ASSIGN
FRAME = FRAME FRAME01:HANDLE
ROW = 3
COLUMN = 14
HEIGHT = 1
WIDTH = 15
HIDDEN = no
SENSITIVE = yes.




ASSIGN
chCtrlFrame = CtrlFrame:COM-HANDLE
UIB_S = chCtrlFrame:LoadControls( OCXFile, "CtrlFrame":U)
CtrlFrame:NAME = "CtrlFrame":U
chCtrlFrame-2 = CtrlFrame-2:COM-HANDLE
UIB_S = chCtrlFrame-2:LoadControls( OCXFile, "CtrlFrame":U)
CtrlFrame-2:NAME = "CtrlFrame-2":U
.


VIEW FRAME frame01.

=========================================================================================

Right now, i want to make the above program more eficient as the variable for widget-handle and com-handle should i create as much as how many button that i want to create

If anyone have another opinion about my program, please let me know.

One can learn something new every day - I did not think that it is possible ... hats off to you!

Instead of creating YASOV (yet another slew of variables) I would keep track of the buttons in a Temp-Table that contains 1 record per button.

Agreed RHD - a temp-table is definitely the best course of action for all the handles.
