Correctly initializing the COM library from V8Handler

[mrp]

Not sure if this is even a question to this forum (apologies if so) but I am trying to call an executable that requires elevated permissions from the V8Handler in the render process. But calling the CoInitializeEx() results in an exception in the KernelBase.dll. Doing the same from the browser process handler (Handler::OnQuery()) succeeds.

This is the code snippet:

Code: Select all

      class V8Handler : public CefV8Handler
      {
      public:
         V8Handler()
         {
            ...
         }


         virtual bool Execute(const CefString& name, CefRefPtr<CefV8Value> object, const CefV8ValueList& arguments,
            CefRefPtr<CefV8Value>& retval, CefString& exception)
         {      
                 ....
                 ....
   
                 SHELLEXECUTEINFO sei;

                 ZeroMemory(&sei, sizeof(SHELLEXECUTEINFO));

                 CoInitializeEx(NULL, COINIT_APARTMENTTHREADED);

                 sei.cbSize = sizeof(SHELLEXECUTEINFO);
                 sei.lpVerb = L"runas";
                 sei.lpParameters = cmd;
                 sei.lpFile = file;
                 if (!ShellExecuteEx(&sei))
                 {
                    DWORD le = GetLastError();
                    error = GetErrorString(le);
                    result = false;
                 }

                 CoUninitialize();


Any ideas what I am doing wrong.

Thanks,
