Hi Tim

Thats one of the best approaches. ^^

Used this construct:

FFaceApi fface = null; Native.setProtected(true); for (int j=0; j < 7; j++) { fface = (FFaceApi) Native.loadLibrary( flipFlop ? "Test2" : "FFACE", FFaceApi.class); System.out.println(">>> "+(flipFlop ? "Test2" : "FFACE") +" "+fface.GetInventoryItem(1, 0)); }

When GetInventoryItem() returns a struct, the test2.dll returns steadily a properly filled structure while fface.dll returns random values. Changing GetInventoryItem()'s signature to return int's both dll deliver steadily the right value.

So, given these test results your conclusion is that there is something wrong with FFACE.dll? Dumb question: Does the evaluation of structure contents work aswell if the data is coming from another process? Saying process A is producing data, fface.dll is accessing that process and delivering data from there to Process B. No idea why it should work with int then, but just asking.
