Bug ID: 158557
Summary: I am trying to use COM on Windows to load an
OpenOffice Writer object in a window but it fails
Product: LibreOffice
Version: unspecified
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
I am embedding a new LibreOffice text document in another window, but it fails.
After building LibreOffice... I discovered that the code that creates class
factories for creating the various LibreOffice objects, immediately deletes
them...
app.cxx line 1917
1917 xSMgr->createInstance("com.sun.star.bridge.OleApplicationRegistration");
1918 xSMgr->createInstance("com.sun.star.comp.ole.EmbedServer");
the assembly code is
xSMgr->createInstance("com.sun.star.bridge.OleApplicationRegistration");
5B148004 lea edx,[xSMgr]
5B148007 push edx
5B148008 call
com::sun::star::uno::Reference<com::sun::star::lang::XMultiServiceFactory>::operator->
(5B13DCC0h)
5B14800D add esp,4
5B148010 mov dword ptr [ebp-20h],eax
5B148013 mov eax,dword ptr [ebp-20h]
5B148016 mov ecx,dword ptr [eax]
5B148018 mov edx,dword ptr [ecx+0Ch]
5B14801B mov dword ptr [ebp-48h],edx
5B14801E movzx eax,byte ptr [ebp-0Fh]
5B148022 push eax
5B148023 push 5B25AC88h
5B148028 lea ecx,[ebp-24h]
5B14802B call rtl::OUString::OUString<char const [47]> (5B1321F0h)
5B148030 mov byte ptr [ebp-4],2
5B148034 lea ecx,[ebp-24h]
5B148037 push ecx
5B148038 lea edx,[ebp-4Ch]
5B14803B push edx
5B14803C mov eax,dword ptr [ebp-20h]
5B14803F push eax
5B148040 call dword ptr [ebp-48h]
5B148043 add esp,0Ch
5B148046 lea ecx,[ebp-4Ch]
5B148049 call
com::sun::star::uno::Reference<com::sun::star::uno::XInterface>::~Reference<com::sun::star::uno::XInterface>
(5B13BFC0h)
5B14804E mov byte ptr [ebp-4],1
5B148052 lea ecx,[ebp-24h]
5B148055 call rtl::OUString::~OUString (5B13CED0h)
Since this code never gets called again, attempts to create COM objects time
out because the class factory is missing.
Steps to Reproduce:
1.Try to embed a Libre Office object using COM
2.
3.
Actual Results:
The code times out and Windows gives an error
Expected Results:
It should display the new document in the window
Reproducible: Always
User Profile Reset: No
Additional Info:
let me know what this is fixed ([email protected])
