IE ActiveX problem

[James Bott]

I am trying to view an XML file using IE and activeX. When I call the function using the ON INIT clause of ACTIVATE WINDOW it works fine. But when I call the same function from a button all I get is a blank screen. See my code below.

I have tried putting sysfresh() in several places but that didn't help.

Any ideas?

I am using FWH Sept 2006 build/ xHarbour. You can use any HTML or XML file to test the code.

Code: Select all  Expand view

#include "fivewin.ch"

function main()
   local oWnd, oBar
   define window oWnd
   define buttonbar oBar of oWnd
   define button of oBar action viewXML()  // Doesn't work
   activate window oWnd on init viewXML()  // Does work
return nil

function viewXML(cFile, cPath)

   local oWnd, oActiveX, oBar

   default cPath := (cFilePath( GetModuleFileName( GetInstance() ) ))
   default cFile:= "test.xml"

   DEFINE WINDOW oWnd TITLE "Test XML Report"

   oActiveX = TActiveX():New( oWnd, "Shell.Explorer" )

   oWnd:oClient = oActiveX

   oActiveX:Do( "Navigate", cPath+cFile )

   ACTIVATE WINDOW oWnd

   oActiveX:end()

return nil

Hello

Same as me.
I don't know FWH's ActiveX problem or Compatible problem as code.

Hi James,

I have not yet played with ActiveX but I tried messing aroud with your sample.

Strange but if you REMOVE the:

oActiveX:End()


It will work via the button.

Hope this helps.

Hi All !

For any window dialog, please do not put anything after this :

ACTIVATE WINDOW oWnd

>>> oActiveX:end() <<<<
Sometimes get error.

Change to :
ACTIVATE WINDOW oWnd valid ( oActiveX:End(), .t. )

Jeff and Areang,

Thanks a lot guys! It works great now. I was pulling my hair out all day trying to solve that. I would have never guessed that the End() call was the problem. It doesn't seem logical.

Antonio, any idea why that is happening?

No, it is logical. Your secondary window is modeless and oActiveX:End() method is therefore called immediatly.

Duh, I was thinking it was a dialog. I need some sleep--I only had three hours last night...

Hmm, then why doesn't the activeX object get closed when called from the ON INIT clause?

Probably because the second window is modal if created in the ON INIT clause?

Enrico,

>Probably because the second window is modal if created in the ON INIT clause?

That would be a good reason.

James

[Antonio Linares]

Enrico is right, the main window is modal and others windows are non modal. If ON INIT clause used then the second window is activated as the main one, thus it becomes modal.

Hello,

How can I make the window visible? When activate the window, it runs minimized and I have to click on application on taskbar for window to appear and allow user to continue.

DEFINE WINDOW oWnd2 FROM 0, 0 TO 40, 85 MENU oMenu
oActiveX = TActiveX():New( oWnd2, "Shell.Explorer" )
oWnd2:oClient = oActiveX
oActiveX:Do( "Navigate2", cAesdd + cHan )
ACTIVATE WINDOW oWnd2 VALID ( oActiveX:End(), .T. )

Thank You,

[James Bott]

You could try:

ACTIVATE WINDOW oWnd2 VALID ( oActiveX:End(), .T. ) ;
on init BringWindowToTop( oWnd2:hWnd )

Hi James,

Thank you for your response. Unfortunately that did not work. Can I try something else?

[James Bott]

Darrell,

Can you provide us with a working example that we can test?
