Is Qt4.3 such Fragile? uuid problem!
Message 1 in thread
I use vs2003 open a project on:
C:\Qt\4.3.0\examples\activeqt\wrapper\wrapperax.vcproj
I made a single change on main.cpp Line 100:
Change the last digit from “8” to “9”
return "{6E795DE9-872D-43CF-A831-496EF9D86C68}"; // the last 8 to 9
Then, rebuild.
I then open PowerPoint and try to insert QCheckBox control from View ->
Toolbars -> Control Toolbox -> Toolbar Options -> More Controls”.
I got error:
“Object library invalid or contains references to object definitions
that could be found”
(See attached screen snapshot)
Such a fragile? I cannot believe. Please test by yourself. I hope not
happen on your machine.

I foget to say the original works well, but change "8" to "9" makes
QCheckBox control not insertable to PowerPoint.

Try registering it using:
regsvr32 /i wrapperax.ocx (or whatever it is called)
and/or
regsvr32 /i wrapperax.dll

I tried and obtain a message box:
"
wrapperax.dll was loaded, but the DLLInstall entry point was not found.
This file can not be registered.
OK
"
Any more idea?
Thank for your kind reply.

Without "/i" can be registered successfully, however, still the
QCheckBox is not insertable.

Hi,
It looks like that Office applications uses a Type Library cache. When you
changed the class information of the QCheckBox this cache entry became
invalid. This can be verified using the oleview tool (you can see two Type
Library entries for wrapperax). Once you clean the entry created by office
(both the registry entry and the file it points to), you should be able to
insert QCheckBox again in your office application.

Hi Prasanth,
This is a great help. It works after I delete the *.exd file from ppt11.0.
What I did:
1) delete exd file from ppt11.0.
2) search by uuid in regedit, and delete them from registry also.
Problem is when I typed oleview, I still saw them in Type Libraries.
Would you please tell me how to remove it properly?
Thank a lot.

Never mind this question.
I double checked. After I delete it from regedit, it does disrepair in
oleview.
Thank again.
