How to set the size of an ActiveX control? [message #452608]

I have embedded a custom (inhouse developed) ActiveX control via the
OleControlFrame and OleControlSite classes. When displaying the control
(OLE.OLEIVERB_OPEN) its size is fixed by 32 x 32 pixels. Even changing
the layout (GridLoyout) or the boundaries of the frame or the site
doesn’t help. When displaying the control by OLE.OLEIVERB_PRIMARY it
shows up as dialog with the expected size.

Is it necessary to set some properties (width, height) of the ActiveX
control?

Thanks in advance,
Thomas

Maybe you need to invoke OleFrame.setBounds on your OleFrame instance every
time your widget (that hosts your ActiveX and probably extend SWT composite)
is resized.

Listener listener = new Listener() {
public void handleEvent(Event e) {
switch (e.type) {
case SWT.Resize: {
frame.setBounds(getClientArea());
break;
}
....
};
addListener(SWT.Resize, listener);

where frame is a reference to your OleFrame.

That's how the SWT Browser widget is doing it on Windows, look for
SWT.Resize at

This would depend on the ActiveX control. For most controls, they just take
the size of the OleFrame. The OleFrame calls
IOleInPlaceActiveObject.ResizeBorder every time the OleFrame resizes to
inform the ActiveX control about size changes. Do you implement
IOleInPlaceActiveObject.ResizeBorder in your activeX control? What happens
if you use OLEIVERB_INPLACEACTIVATE?

OLEIVERB_INPLACEACTIVATE causes the same situation.

We are using the XSal2 ActiveX control
(http://www.iceteagroup.com/Products/XSal2.htt) to wrap an existing
Centura/SQL Windows application. This ActiveX control probably does not
implement the required interface. I’m trying to get more details about
XSal2. By the way, in C# the size can be controlled by setting the
Width- and Height-property.

Has anybody already integrated a Centura/SQL Windows application into
Eclipse?

Implementing a listener doesn’t help. Probably, the ActiveX control
(XSal2 - http://www.iceteagroup.com/Products/XSal2.htt) that we are
using to integrate an existing Centura/SQL Windows application does not
provide the required interfaces (IOleInPlaceActiveObject).

You could probably also set the width and height property in SWT using
OleAutomation.setProperty().

For more details about OleAutomation see:

Width and Height are not properties of the XSal2 ActiceX control itself
(only ApplicationName and FormName are accessible via OleAutomation). I

I think, that the C# statements

axXSalForms1.Width = 400;
axXSalForms1.Height = 200;

can be compared to the SWT statements

OleFrame frame = ...;
frame.setBounds(1, 1, 400, 200);

What is the minimal set of interfaces an ActiveX control must implement
to be displayed within an OleFrame container (sorry, I’m not familiar
with ActiveX development at all)?

SWT uses OleCreate for non-licensed ActiveX controls. See the MSDN for
information about interfaces OleCreate requires.
