calling unmanged code from j#
-
i have an unmanaged dll that exports a function that takes a TCHAR* parameter. i need to call this function from j#. in my j# file, i tried to set the marshal attribute like so, public static native void testStringFunction(/** @attribute MarshalAs(UnmanagedType.LPTStr)*/String s); when i call that function, my string is not marshaled to a TCHAR*. i tried all the different string types in the UnmanagedType enumeration. anyone have any ideas?? thanks.

Did you attribute it with the
DllImportAttribute, specifying the right native DLL? You should also specify in that attributeCharSet=CharSet.Auto. Other than that, your code looks fine.-----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?
