Hi. I made several test with dll examples available for downloading in udn official page:

http://udn.epicgames.com/Three/DLLBind.html

I tried with the one that comes with a DLL compiled and I can't get it work with my 64 bit UDK Release(One of the last releases). I tried to run UDK.exe make -full from both folders, win32 and win64, but i get a Warning message indicating that bind could not be done (from one folder i get it at compiling time, and from the other it is registered on log file).

I've also tried to compile a 64 bit dll from Visual C++ 2010 Express. And the result is the same. Is Actually UDK supporting 64 bits dll? Anyway there's must be some bug with latest 64 releases, since i cannot bind a 32 bit dll though...

Any clue?

Thanks

Quoting your link:
Limitations
  • Only Unicode (UTF-16) strings are supported. Compile your DLL with Unicode enabled.
  • As only the 32-bit version of UDK is currently available, only 32-bit DLLs are supported. At such time as a 64-bit version of UDK is available, 64-bit DLLs will be supported.
  • DLLs can only be loaded from Binaries\Win32\UserCode.
  • Under Win32, only stdcall is supported. (See this link for information about calling conventions).

I'd say it's a bit outdated, as obviously UDK comes with a 64bit version by now. However, over in the Epic Games UDK forum I often see people asking for 64bit DLLbind, which still doesn't seem to work as expected.

Where did you put your DLL file?

Yes, I supposed that the problem with official page dll might be that is outdated... I tried everything. Putting dll on win32/userCode and win64 folders, launching udk.exe make -full from both win 32 and 64 folders. Made all combinations :)

I read on the official page that 64 bits dll were not supported, but i thought that documentation was also outdated...

So at the moment only works launching udk.exe from win32 folder and binding 32 bits dll, isn't it? Knowing this fact i may enclose the problem...
