问题 I am attempting to register for notifications on USB device arrival and device remove complete events from a java swing application. I have successfully called SetWindowLong(hWnd, MyUser32.GWLP_WNDPROC, listener); to register a listener and I am getting notifications of type WM_DEVICECHANGE . So far so good. Now I want to call RegisterDeviceNotification to ensure that I am notified of device arrival and remove complete events. Here is what I have tried: HWND hWnd = new HWND(); hWnd.setPointer

问题 I trying to read coordinates from a game. This works perfectly fine, when using ReadProcessMemory on a HANDLE that I receive through OpenProcess, with the memory I find in CheatEngine. For example, if I know the float value in the running process is at 0x5AB38F68, I can read this. However, the address changes everytime the game restarts. It depends on a module called AkSoundEngine.dll. So basically the address would be at AkSoundEngine.dll+0x168F68. However, I cannot for the life of me find

问题 I have an array of bytes and I want to pass it to C function using JNA. However I only found examples which allocated a pointer using new Memory and used write function to copy array data but for me is not acceptable because I have big block of data. Is there a possibility just to pass my Java array directly to c library ? I want to do something like this : MyLib lib = Native.loadLibrary("test"); Pointer p = myByteArray; //I want to make it possible lib.someFunction(p); 回答1: Passing a

问题 I'm trying to call a function in a delphi dll using JNA. the function definition is: function myFuncGetName (aHandle : THandle; var aBuf : pwideChar ): integer; export; my jna mapping looks like this: int myFuncGetName(PointerByReference aHandle, WString aBuf); the return value should be 0 for success and -1 for fail and I'm always getting -1. I have started up WinDbg and attached to the process and it breaks at myFuncGetName. 057cb384 eb11 jmp myDLL!myFuncGetName+0x87 (057cb397) 057cb386
