definition Language,idl). IDL is the language used to define function flags, which is independent of the various programming languages, allowing the RPC bottom to package, load, and unpack parameters between different computers. In our Iadd interface, we have the Setfirstnumber and Setsecondnumber methods, which are used to pass the parameters of addition. There is also a method, dotheaddition, that is used to complete the addition and pass the results back to the client. 1th Step: To create

this option. Here, add three parameters, where result is returned (the retval parameter is checked ). If you select retval, you will not be added to the parameter again, indicating that only one return value is allowed. Check only the out parameter. js has no effect.

. • Check the version number of the managed automated OLE system file. These files are usually installed as collections. These files must match the internal version number. The installation utility with incorrect configuration may mistakenly install these files separately. This causes file mismatch. To avoid automation problems, check the file to ensure that the file version matches.The automatic file is located in the Windows/system32 directory or WINNT/system32 directory. Check the

On msdn, you can find that IObjectSafety inherits from iunknown and is a custom interface. Through the previous chapter, you can find that when registering with COM, a guid must be provided as the CLSID to identify the C # class in the Assembly. In fact, in COM, the interface and Type Li

The stdpicture class has two interfaces, including the picture interface and the ipicture interface. The picture interface is the default Interface of stdpicture, so to some extent, there is no error when the stdpicture type is equal to the picture type (because the ipicture interface is rarely used) The ipicture interface has more attributes than the picture interface, as shown in the following (incomplete ): Attributes Curdc Keeporiginalformat Type, etc. The pictue attribute of our common VB
