Details of dll or plugin:
If the plugin or dll can't connect to pipe or by disconnected, it unload it self.

Choice of communication mode:
The named pipe, that's isolate language and architecture, the you can use plugin/dll 64Bits with 32Bits application.
You can too code the dll in c++ with application in pascal. And it's only local. That's allow too detect when the application is closed or crashed.

Recomposition and decomposition:
For plugin/dll, the data need be cut in 32KB max, each term will be preceded by its size in 32 bits.
The application need regroup the packet , and remove the 32Bits of size.

Encoding used:
The choice is utf16 big endian. For better multi-platform, and all the OS use it now.

Example:
Data cleaned and recomposed:

0000DC79 00000001 0000001800460069006c0065004500780070006c006f007200650072 000000060000000200610000000400610062000000060061006200630000000800610062006300640000000a006100620063006400650000000c006100620063006400650066

0000DC79 is the id of the copy, generated by the system that's connecting to the application charged of the copy.
00000001 is the version of the protocol
00000018 (string size in byte) 00460069006c0065004500780070006c006f007200650072 -> "FileExplorer" is the string for identify the system/explorer connected at the copy application.
After visual cutting for the example:

• 00000006 List size
• 00000002 (string size in byte) 0061 -> a
• 00000004 (string size in byte) 00610062 -> ab
• 00000006 (string size in byte) 006100620063 -> abc
• 00000008 (string size in byte) 0061006200630064 -> abcd
• 0000000a (string size in byte) 00610062006300640065 -> abcde
• 0000000c (string size in byte) 006100620063006400650066 -> abcdef

The reply:
When the copy is done (success or failure), we resend the copy id if no egal to 0:

Code: Select all
