39155 - ActiveX control cannot be used at all from within Delphi.

Status: VERIFIED DUPLICATE of bug 2111

(Core Graveyard :: Embedding: ActiveX Wrapper, defect, P3)

Description

[Simon Steele]

The control appears to be created OK with the default type-library import, and 
causes no problems at all at first. When you first load it, it asks for the 
location of Mozilla which it remembers, and then no problems. As soon as you 
try to navigate anywhere, the exception:

EOleException: Method called while control is uninitialized.

is raised. This is better to previous nightly build which crashed outright with 
an access violation. I'm not sure what extra details I could provide. I am 
calling the standard create routine present in the import.

I don't know much about Delphi, but you could try talking to Nick Bradbury at 
Bradsoft since he was doing some work with the control a while back. I don't 
have a contact address on me but there may be one on the website: 
http://www.bradsoft.com/topstyle/index.asp

From what you're saying here it looks like you are calling a method before the 
control has been activated. Is there a property or a method that Delphi requires 
you to explicitly call or set before a control will work? Are you calling the 
method somewhere before the control has been created properly such as during 
WM_CREATE/WM_INITDIALOG?

I suspect that this is the same problem as some people using VB were reporting 
in bug 42239. I don't know for sure what caused the problem, but it was not the 
control itself because it had not changed at all around the time the bug was 
raise. I think it was caused by subtle changes in the docshell initialization 
code. Please try out the control I put up on my website and see if the problem 
still persists:

For the time being, I'll assign this bug to myself but I should be able to close 
it as soon as the next control checkin happens (within a day or so).

Attachment: Diff to call OnStartURIOpen on the content listener when the URI is unrecognized. Review/approval please

Comment 7

[Adam Lock]

Ignore this patch - wrong bug!

Comment 8

[Adam Lock]

Please test the control from the latest nightly with Delphi please.

Comment 9

[Adam Lock]

In the absence of confirmation that this is still a problem, I'm marking this as
a duplicate of 2111 which will be a catch-all bug for Delphi-specific problems
with the control.

Duplicate of bug 2111 -Mozilla Layout control does not work properly in a
Borland Delphi 4 compiled program.
