RAPPS fails to format error message when network is down and misses MessageBox to the user

Using : reactos-bootcd-0.4.15-dev-4914-g2220e56-x86-gcc-lin-dbg

• Open RAPPS
• Unplug network cable
• Download and app

Fails (as expected) but RAPPS fails to properly format the error message and logs says : loaddlg.cpp:548: (base/applications/rapps/loaddlg.cpp:548) FormatMessageW unexpected failure (err 1813)

as a consequence no error message is shown to the user as MessageBoxW(hWndOwner, lpMsg, NULL, MB_OK | MB_ICONERROR); is not executed

 

Culprit code section :

if (!FormatMessageW(FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_IGNORE_INSERTS |
(bInetError ? FORMAT_MESSAGE_FROM_HMODULE : FORMAT_MESSAGE_FROM_SYSTEM),
(bInetError ? GetModuleHandleW(L"wininet.dll") : NULL),
dwLastError,
LANG_USER_DEFAULT,
(LPWSTR)&lpMsg,
0, NULL))

{ DPRINT1("FormatMessageW unexpected failure (err %d)\n", GetLastError()); return FALSE; }
