We have a DLL that keeps giving AV errors. It seems to be linked with the Ribbon bars. Below you can see the exception log.
Any ideas ?

Hello Mark.
First, please accept my apologies for the delay in responding.
Unfortunately, this information is not enough to determine the exact cause of this problem. Please try to create some example to reproduce this problem and attach it to your next message.
We suppose that this problem is related to incorrect initializing of the DLL with Ribbon. Do you call the dxInitializeGDIPlus/dxFinalizeGDIPlus methods in your DLL?
Please review the following reports, which contain helpful information:
B142804: OCX with a dxRibbon causes error when creating
B94305: Need to Call dxFinalizeGDIPlus before free library
B93061: AV exiting DLL with DX components
Best regards,
Ingvar.
The procedure that is causing the problem has not been changed for at least 6 months. The AV problem has only really started in the past 3-4 weeks. I use many .dll's and call them all in the same fashion - see below
I'll have a look at your suggested links (one of which was mine a while back !) - and see if it sheds any light on the problem.
Mark
Handle := LoadLibrary('STOKERS_EMAIL.DLL');
if Handle <> 0 then
begin
try
@SendMessage := GetProcAddress(Handle,'Send_Message');
dxInitializeGDIPlus := GetProcAddress(Handle,'dxInitializeGDIPlus');
if Assigned(dxInitializeGDIPlus) then
dxInitializeGDIPlus;
if @SendMessage <> nil then
SendMessage(Application.Handle);
finally
dxFinalizeGDIPlus := GetProcAddress(Handle,'dxFinalizeGDIPlus');
if Assigned(dxFinalizeGDIPlus) then
dxFinalizeGDIPlus;
FreeLibrary(Handle);
end;
end;
Hello Mark.
Thank you for the response.
Unfortunately, I did not manage to reproduce this problem. Attached is an example that works as expected on my side. Please modify it to illustrate the problem or provide us with your own sample project. We will test it and try to find an acceptable solution for you.
Best regards,
Ingvar.
