Office Programming-Why RPC server is unavailable

The following problems occur when the RPC server is unavailable:

1. The object is closed externally (for example, through the Task Manager)

2. The access control of operation objects cannot be implemented. Sequential or inter-thread access may cause unavailability of the RPC server.

The solution is to control the frequency of continuous access and perform some other processing after N accesses, such as moving the cursor position in the Word document before proceeding with the processing. Inter-thread access is easier to solve.

3. If the versions of the referenced office operating database are inconsistent, the RPC server may become unavailable on some machines, this problem occurs mainly because the referenced versions are inconsistent because of automatic GAC reference, and SVN is not easy to find this problem. You only need to ensure that all referenced office libraries are consistent, the main involved libraries are word. DLL, Excel. DLL, office. DLL, VBE. DLL (mainly for Word and Excel operations ).
