  1. INVALID_ACCESS_VIOLATION

    Hi All I get this error when I am trying to access a winapi function. The code is as follows: try { foo = new xFunction("Advapi32", "int GetUserNameA(CSTRING, int)"); //foo = new xFunction("kernel32", "int Beep(int,int)"); } catch (Exception xe) { System.out.println("XFunction Init Error:" + xe.toString()); } try { Argument[] args = new Argument[2]; StringBuffer sb = new StringBuffer(); int iCount = 0; for (iCount=0; iCount < 1024; iCount++) { sb.append(" "); } uName = sb.toString(); Argument CompName = new Argument(uName, Argument.CSTRING); Argument iSize = new Argument(iCount); args[0] = CompName; args[1] = iSize; foo.invoke(args); uName = (String) args[0].getValue(); //int ret = ((Integer) foo.invoke(new Argument(463610), new Argument(1024), new Argument(0), new Argument(0))).intValue(); //foo.invoke(new Argument(1770), new Argument(100)); } catch (Exception xe) { System.out.println( "Could not get computer name." + xe.toString()); return err; } The Error message is as follows: An unexpected exception has been detected in native code outside the VM.
