Synergy-core: Drag and Drop for Files is not working

Created on 3 Feb 2016  路  11Comments  路  Source: symless/synergy-core

Hi,

I am using Windows 10 as the Server and Mac OSX as the Client.
Everything works great except for the drag and drop of files from both Windows and Mac.

Everytime I drag a file from Windows, the moment I reach the edge, the file is no longer getting dragged and I get a Window in the Taskbar with title DropWindow. After repeating the same for couple of times, I could see the application is synergys.exe in the Task Manager.

I have recorded the screen as well for the activity:

With synergy-v1.8.2-rc1-12e0120, drag and drop files not working for Windows 10 (server) Mac OSX (client). Sending files in either direction does not work.

I basically have the same problem. Both client and server are Windows 10, and when it gets to the edge of the screen, it says it "failed to get drag file name from OLE"
relevant log section below:
synergy-debug2.txt

devnuhl picture devnuhl on 12 May 2016

I was mistakely used the old-version synergyd.exe.
However, after I fixed that, It still not working and I got the same "failed to get drag file name from OLE" mentioned above(with or without elevate mode)

wywzxxz picture wywzxxz on 14 May 2016

I think it's a localization problem.
the error "failed to get drag file name from OLE" is not neccessry means OLE can't get file name , but also OLE got a filename but Synerigy can't be open it .
In my test,once the filename contains a chinese word, I got a OLE error,and high chance to crash synerigy.
And then I found something realy strange: when a pure english filename contains a space,it will not throw OLE error but It also crash Synerigy.dont know why for now

FOR UNICODE:
wcstombs need setlocale to work appropriatly,otherwise it will ignore chinese/or other unicode language.
setlocale(LC_ALL,""); //use the locate setting from the machine
wcstombs(filename, wcData, 2*wcslen(wcData));
setlocale(LC_ALL,"C");//use the default locate

UPDATE

no, space or long spaces don't crash synergy,it's something else.

notice: since Synerigy's file transfer works in a super silenct way(no dialog銆乶o notice銆乶o asking when name confilct,basically don't ),so in some case(file name confiltct銆乻uper bad network) ,It works but don't looks like
