TActiveX:SetProp()

reinaldocrespo · Post by **reinaldocrespo** » Tue Jul 24, 2007 8:33 pm

Hi.

I'm having a problem setting one specific property to an ocx I'm using. All else works just fine.

From the OCX guide, the property data type is described as:

VARIANT=> Variant type (C/C++ type OLEVARIANT, Delphi type OleVariant, VB
type Variant (default type))
...And can be assigned to the .AcmFormat property directly, e.g.:
ocx.AcmFormat = "31000100401f0000590600004100000002004001"

On my fwh code I'm assigning this way:

Code: Select all

	cAcmString := "55000100c05d0000b80b0000010000000c00010002000000480001007105"

	::oActiveX:SetProp( "AcmFormat", cAcmString )

But it does not seem to work. After the property has been set (with the code above), when quering it I get back Nil which is the default value before it is set.

Can anyone help with this one?

Reinaldo.

Reinaldo,

have you tried to assign a shorter string, just for a test ?

::oActiveX:SetProp( "AcmFormat", "123" )

Antonio;

Yes, I have. Nothing gets assigned. I think it has to do with the Variant data type that is expected.

Reinaldo,

Are you using harbour or xharbour ?

xharbour.

Reinaldo,

Please do this: tlib fivehc.lib - ole.obj

and try it again

Reinaldo,

Please try this:

Code: Select all

function OleGetProperty( hObj, cPropName )

   local o := TOleAuto()

   o:hObj = hObj

return __ObjSendMsg( o, cPropName )

function OleSetProperty( hObj, cPropName, uValue )

   local o := TOleAuto()

   o:hObj = hObj

return __ObjSendMsg( o, "_" + cPropName, uValue )

function OleInvoke()

   MsgInfo( "not implemented yet" )

return nil

I see what you are trying to do. But I'm using fwh Tactivex class. Now this piece of code fails.

Code: Select all

TRY
	::oActiveX := TActiveX():New( ::oWnd, "MSSR300.MSSR300Ctrl.1" )
END

I get the msginfo "not implemented yet".

Reinaldo.

Reinaldo,

Please make this change to force an error and see where OleInvoke() is called from, thanks

Code: Select all

function OleInvoke()

   x++

return nil

reinaldocrespo · Post by **reinaldocrespo** » Wed Jul 25, 2007 3:13 pm

I did this instead:

Code: Select all

function OleInvoke() 
local x
   x++ 

return nil

Got this:

Reinaldo,

Don't you get more calls previous to ?

Called from: ACTIVEX.PRG => TACTIVEX:DO(0)

No. That's an actual cut and paste from the error.log file.

Reinaldo,

What source code do you have here ?

tVoiceRec.prg => TMSSR300:INIT(57)

Try to comment it out, if possible

Line 57 is:

Code: Select all

	::oActiveX:do( "Reset" )

But remember that I included:

Code: Select all

function OleInvoke()
local x
   x++    //<== this is line 789

return nil

Please allow me to send you the ocx with its documentation and sample code for your testing. I can create a very small .prg sample code.

Reinaldo.
