A TActiveX working sample using Acrobat Reader 7

[Enrico Maria Giordano]

Here it is:

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oWnd, oPdf

    DEFINE WINDOW oWnd

    oPdf = TActiveX():New( oWnd, "{CA8A9780-280D-11CF-A24D-444553540000}" )

    oPdf:Do( "LoadFile", "filename" )

    oWnd:oClient = oPdf

    ACTIVATE WINDOW oWnd

    RETURN NIL

This is an alternative:

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oWnd, oPdf

    DEFINE WINDOW oWnd

    oPdf = TActiveX():New( oWnd, "AcroPDF.PDF" )

    oPdf:Do( "LoadFile", "filename" )

    oWnd:oClient = oPdf

    ACTIVATE WINDOW oWnd

    RETURN NIL

But they have a problem: the process AcroRd32.exe remains active after the end of the sample execution. Is there any way to unload it? I already tried various options without success: oPdf:End(), oPdf:Do( "Close" ), DeleteObject( oPdf:hActiveX ), etc.

Enrico,

Have you checked if after some time it gets unloaded ? Sometimes the activex remains loaded for some time and later on it gets closed.

[Enrico Maria Giordano]

No, I will check it, thank you.

Enrico,

Antonio, is there a way to know if the Activex Control is already loaded on memory, and a way to unloaded it if is true.

While doing some tests with an epson ocx, I got plenty of problems, I needed to reboot to make things work, so I think it was because it get loaded...

Any idea

Adolfo,

With some OCXs, like Acrobat Reader, if you press Ctrl+Alt+Del you can see AcroRd32.exe is loaded.

On some other OCXs where EXEs are not used, it may be more difficult to know it.
