int ret = document.Open(“[Document_Path]”,”[Document_Password]”)

* [Document_Password]: set to “” if the document is not encrypted.

Process document open result:

private void ProcessOpenResult(int ret) {
switch( ret ) {
case -1:
//Failed: need input password
case -2:
//Failed: unknown encryption
