My questions :
1. Can I get property on MyOCX, like VB
2. Can I create class to call MyOCX property

Areang,

> 1. Can I get property on MyOCX, like VB

You may use Microsoft OleView to inspect the properties, methods and events of the ActiveX that you are going to use. Another choice is to install if from Microsoft Office built in VBA (macros editor in Word, Excell, etc.) and inspect it from there.

> 2. Can I create class to call MyOCX property

You may use ERROR HANDLER OnError( uParam1 ) to route PRG msgs to Class TActiveX Methods GetProp, SetProp and Do. Please review source\classes\database.prg to see how to use ERROR HANDLER.

[areang]

Thank.
I will try it.

Antonio ! Can you help me about this :

I have CoolControls.ocx, viewed by oleview on :

dispinterface _jcFrames {
properties:
methods:

I can see the methods like this :

[id(0x6803000f), propput]
void Caption([in, out] BSTR* rhs);

Please give me sample about this with complete classes.
to call Caption properties

Thank
best Regard
Areang

[Antonio Linares]

Areang,

Try these:

Code: Select all  Expand view  RUN

local cCaption := ""
...
oActiveX:Do( "Caption", cCaption )
MsgInfo( cCaption )
...
MsgInfo( oActiveX:GetProp( "Caption" ) )
...
oActiveX:Do( "Caption", @cCaption )
MsgInfo( cCaption )

Antonio

I Created the Class, still can't put the caption on the frames
and please also ERROR HANDLER ERROR().

Please Help me !

Here is the sample


#include "Fivewin.ch"

FUNCTION Main()

LOCAL oWnd, oFrames

DEFINE Window oWnd

oWnd:setText( "Use JcFrames from CoolControls.ocx" )

oFrames := Framesx():New( oWnd )

Areang,

To set the caption try this:

oActiveX:SetProp( "Caption", "Hello world" )

[Antonio Linares]

Code: Select all  Expand view  RUN

METHOD ERROR( uParam1 ) CLASS FRAMESX

   local cMsg := __GetMessage()

   if SubStr( cMsg, 1, 1 ) == "_"
      return ::SetProp( SubStr( cMsg, 2 ), uParam1 )
   else
      return ::GetProp( cMsg )

Thank Antonio, It's work now.

Hi Antonio !

This is the first class was create by me, and so happy.

But can't put the others control on this frames to work with my windows.

How to work together between xHB control and myocx control.

when uncomment this "oWnd:oClient := oFrames:oControl"
the others control can work together, Is that true ?

In VB, I can see the properties position :
Height, Left, Top and Width but I can't see on oleview of them.

Can you help me again about this ?

Thank
Best Regard

Areang

[Antonio Linares]

Areang,

>

>

Yes, because oWnd:oClient fills the entire surface of the window with the control, so if you want to use more controls on it, you can't assign it to oWnd:oClient.

Class TActiveX inherits from Class TControl, so you can do:

oActiveX:nTop = ...
oActiveX:nLeft = ...
oActiveX:nWidth = ...
oActiveX:nHeight = ...

[areang]

Antonio !

On activex.prg, I can see the class :

CLASS TActiveX FROM TControl
there is :
METHOD ReSize( nFlags, nWidth, nHeight ) INLINE ;
ActXSetLocation( ::hActiveX, 0, 0, nWidth, nHeight )

Can I use it for position my frames ?

Or I have to add this :

Class TActiveX inherits from Class TControl, so you can do:

oActiveX:nTop = ...
oActiveX:nLeft = ...
oActiveX:nWidth = ...
oActiveX:nHeight = ...

But where to write of this code below :
( Please you write here or on activex.prg )

Areang,

> @100,100 BUTTON "Save" size 60,20 of oWnd pixel action MsgAlert("Save")

That control is a child control of oWnd so oWnd should get notified when it gets clicked and the ACTION clause should work.
