Delphi-Word Automation refresh Issues
Jen Collier [Feb 25 2004, 10:08]

Can anyone help with a few refresh issues that users are experiencing when using word automation from Delphi? 

When users save documents in Word, the whole screen is refreshed and the vertical scroll bar at the right hand side of the screen has duplicated, so there are 2 vertical scroll bars. If the user clicks in the middle of the outer vertical scroll bar, all of the toolbar buttons underneath the drop down menus at the top of the screen completely disappear and the scroll bar changes colour to black. 

The work around at the moment  is for the users to click on the arrow at the bottom of the outer vertical scroll bar to correct the scroll bars so that one remains.

We're using an Ole Container modified to control word, this is the attached word container.pas. The form we use the container in is the DocEdit.pas/dfm. If they save a document (in the OLE Container in Delphi) then we have to clear the document and reload it to make the flag behave correctly.

Users experiencing the problem are using Win XP Professional SP1, application written in Delphi 6.0, Office 2000 standard up to SP3. They are not running Norton anti virus software, but do run an app called Hayes DX which they have to close down before attempting to hook into word from the Delphi app otherwise they get the error message 'call was rejected by callee'.

Any suggestions for the scroll bar phenomenon much appreciated.

WORDCONTAINER.PAS
{Word Interface Component using VBA and TOleContainer to
allow viewing and editing of Microsoft Word documents.

To open a word doc, set CurrentDocFile := 'C:/Path/Docname.doc';
To edit the document on opening, call WordContainer1.ActivateDocument
from FormShow.

To have the Word toolbar appear where you want it, place 2 panels on
a form. One has TWordContainer and Locked := True. The other has
Locked := False and the toolbar will appear there.

Note that the document is deactivated when any other TWinControl gets
focus. Use the Activate button to reactivate the document. A separate
form is used for control buttons to prevent activate/deactivate of
the document whenever a mode change is made.

This app and component are not all-inclusive nor perfect, but they go
a long way toward having a usable Word container.

Re: Delphi-Word Automation refresh Issues
Oliver Townshend [Feb 25 2004, 10:35]

> Users experiencing the problem are using Win XP Professional SP1,
application written in Delphi 6.0, Office 2000 standard up to SP3. They are
not running Norton anti virus software, but do run an app called Hayes DX
which they have to close down before attempting to hook into word from the
Delphi app otherwise they get the error message 'call was rejected by
callee'.

Build a stand alone system which is just WinXP and Office (i.e. no Hayex DX,
or any other unnecessary software).  See if you still have the problem.
