CloseAllDocuments(0) crash

[entropics]

Hello,

We are using the ActiveX SDK With Delphi.

If the first command we issue is CloseAllDocuments(0) then we get an access violation.

Any idea ?

Hi, entropics.

We cannot reproduce this. Can you send to us the simple example with reproducible issue?

Hello,

Here is a very simple program to reproduce it (in Delphi XE6)

Thanks entropics,

I've passed it to a colleague from the dev team that will take a look.

Hi, entropics.

If the first command we issue is CloseAllDocuments(0) then we get an access violation.

Reason of that: you called the CloseAllDocuments() when no one document is opened. In this case this function returns the error code "HAVE NO DOCUMENTS". Your COM-stub generates exception on that, in standard way. To prevent this exception use:

Code: Select all

try
     CloseAllDocuments(0);
exept
     { on ex : EOleException do
        ShowErrorMessage(ex.ErrorCode); }
end;

- for more examples look to our Viewer ActiveX Delphi Examples (<X>:\Program Files\Tracker Software\PDF-XChange Viewer SDK\Examples\DelphiExamples)...

Thank you very much for your answer,

But i'm a little bit suprised that if you call CloseAllDocuments and there is no opened documents, it fails. I would have expected the function to succeed.

Hello entropics,

It does not "fail" - it returns an exception - which was not handled correctly before.
If there are no opened documents - Close All can not "perform" it's operation so that it can exit with a success code and gives you the exception so that you are aware there were no files closed.
