Examples with DWORD com.sun.jna.platform.win32.WinDef.DWORD used on opensource projects

Example 11 with DWORD

use of com.sun.jna.platform.win32.WinDef.DWORD in project jna by java-native-access.

the class RunningObjectTable_Test method Revoke.

@Test
public void Revoke() {
    PointerByReference pprot = new PointerByReference();
    HRESULT hr = Ole32.INSTANCE.GetRunningObjectTable(new DWORD(0), pprot);
    COMUtils.checkRC(hr);
    IRunningObjectTable rot = new RunningObjectTable(pprot.getValue());
//Can't yet be tested as IMoniker is not fully implemented,
// so we can't register an object, and hence can't get a registration key to Revoke one
//rot.Revoke(dwRegister);
}
