PDF Viewer export to Tiff without interface and Delphi

[didierurban]

When i create a PDFView object (Delphi 2006) it's impossible to set properties or anything else before show ?

I want to export to Tiff but without interface, how to create the object without memory Read error... ?

Ah ah i'm not clear.

For example : On delphi formcreate, call the setdevinfo procedure and we get a big crash.

Maybe I'm wrong, but during FormCreate event does Delphi's form and its components already constructed? It is correct to call their methods ?

Yes, i always set properties of activex on formcreate.

Thanks

Don´t know if it´s by design or a bug. I´m also not able to do anything with the activex as long as it´s not visible. Here´s what i´ve tried with some VBA code

---------------------------
Private Sub UserForm_Activate()
olectrl.Visible = False ' hide the control, ok
End Sub

-----------------------

As expected the control isn´t visible, but lateron each attempt to access the control fails with the runtime error "8000ffff" ( translated as "Catastrophic failure" )


------------------------
Private Sub btn3_Click()
Dim xx As Variant

' the next line causes a crash

olectrl.GetProperty "General.ApplicationModulePath", xx, 0
MsgBox (xx)

To Charly:
We cannot reproduce the bug. Can you send your sample project on VB ?

[Charly]

Sorry, but i do not have VB installed. But just open the attached winword document. When you open the doc you must allow to execute makros !.

Now select "Extras" -> "Macros" -> "Visual Basic Editor" and you´re within the VBA IDE. Select the Project: "( PDFXChangeText2 )" and you can see the form-editor and the sources.

BTW. here are the complete extracted sources:

------------------------------

Public nID As Long

Private Sub btn3_Click()
Dim xx As Variant

' olectrl.OpenDocument "C:\huw.pdf", "", nID, 0
' MsgBox (nID)


' the next line causes an runtime error "8000ffff" ( translated as "Catastrophic failure" )
' when you activate the line :
'
' olectrl.Visible = False
'
' in the Sub UserForm_Activate()
'
' otherwise all works as expected.
'

olectrl.GetProperty "General.ApplicationModulePath", xx, 0
MsgBox (xx)

End Sub


Private Sub UserForm_Activate()

olectrl.Top = 0
olectrl.Left = 0
olectrl.Width = UserForm1.Width - 6
olectrl.Height = UserForm1.Height - 80

' olectrl.Visible = False

End Sub

Looks like olectrl.Visible = False causes trouble. For now I don't know who is responsible for this trouble -- the viewer, or Word. So, as a solution for now, you can jut put this control into 'wrong' place of the form, for example to set olectrl.Left = -1000.
