Im writing a server to receive key events from an iPhone. I can send a message from the iPhone and have my server display it, on the Mac, now i just need to translate that into a Key press, and simulate that press in Cocoa.
Could anyone offer me a starting point, as i guess this is quite low level.
Thanks
I believe IOHIDPostEvent may be what you're looking for. Something like this:
static void HIDPostVirtualKey(
const UInt8 inVirtualKeyCode,
const Boolean inPostUp,
const Boolean inRepeat)
{
NXEventData event;
IOGPoint loc = { 0, 0 };
bzero(&event, sizeof(NXEventData));
event.key.repeat = inRepeat;
event.key.keyCode = inVirtualKeyCode;
event.key.origCharSet = event.key.charSet = NX_ASCIISET;
event.key.origCharCode = event.key.charCode = 0;
IOHIDPostEvent( get_event_driver(), inPostUp ? NX_KEYUP : NX_KEYDOWN, loc, &event, kNXEventDataVersion, kIOHIDPostHIDManagerEvent, FALSE );
}

Right, parsing the clipboard, I am trying to detect if a stored bitmap in there might be the result of a screenshot the user took.
Everything is working fine as long as the user only has one monitor. Things become a bit more involved with two or more.
I am using the routing below to grab all the displays in use. Now, since I have no idea how they are configured to hang together, I do not know how to calculate the size of the screenshot (that Windows would produce) from that information.
I explicitly do not want to take a screenshot myself to compare. It's a privacy promise by my app.
Any ideas?
Here is the code for the size extractor, run in the UI thread.
public static async Task<Windows.Graphics.SizeInt32[]> GetMonitorSizesAsync()
{
Windows.Graphics.SizeInt32[] result = null;
var selector = DisplayMonitor.GetDeviceSelector();
var devices = await DeviceInformation.FindAllAsync(selector);
if (devices?.Count > 0)
{
result = new Windows.Graphics.SizeInt32[devices.Count];
int i = 0;
foreach (var device in devices)
{
var monitor = await DisplayMonitor.FromInterfaceIdAsync(device.Id);
result[i++] = monitor.NativeResolutionInRawPixels;
}
}
return result;
}
Base on Raymonds comment, here is my current solution in release code...
IN_UI_THREAD is a convenience property to see if the code executes in the UI thread,
public static Windows.Foundation.Size GetDesktopSize()
{
Int32 desktopWidth = 0;
Int32 desktopHeight = 0;
if (IN_UI_THREAD)
{
var regions = Windows.UI.ViewManagement.ApplicationView.GetForCurrentView()?.WindowingEnvironment?.GetDisplayRegions()?.Where(r => r.IsVisible);
if (regions?.Count() > 0)
{
// Get grab the most left and the most right point.
var MostLeft = regions.Min(r => r.WorkAreaOffset.X);
var MostTop = regions.Min(r => r.WorkAreaOffset.Y);
// The width is the distance between the most left and the most right point
desktopWidth = (int)regions.Max(r => r.WorkAreaOffset.X + r.WorkAreaSize.Width - MostLeft);
// Same for height
desktopHeight = (int)regions.Max(r => r.WorkAreaOffset.Y + r.WorkAreaSize.Height - MostTop);
}
}
return new Windows.Foundation.Size(desktopWidth, desktopHeight);
}
I'm writing an application in C# to remote control another application. I don't have access to that application yet, but it's most likely written in either Visual C++ or VB6. I'm currently remote controlling a simple C# winforms program I created instead. So far, I can get all of the controls in a manner similar to Spy++ using PInvoke. I can also do things like setting the text in a textbox. The problem I have is that I can't uniquely identify a specific text box between executions of the application I'm controlling. I can't use hWnd for example because it's different every time you run the application. GetWindowLong returns whatever the hWnd is so that's no help. The internet speaks of this message called WM_GETCONTROLNAME. The scary code below attempts to use that message to get the name the developer used to uniquely identify the controls. The SendMessage seems like it's returning the number of bytes in the name. But the buffer containing that name comes back all zeros.
So here's the question. How can I fix the code below so that it returns that name correctly? (Hopefully it's a boneheaded mistake that's easy to fix) Or, just as good, is there some other ID that will be guaranteed to be the same every time I run the program? Without something to uniquely identify the textbox controls, my code can't tell them apart.
I do have a hack in mind. It seems to me that using the position of the textboxes to tell them apart would work. But I'd much prefer to have the code below working.
public static string GetWindowText(IntPtr Handle)
{
int BufferSize = 256;
uint Message = RegisterWindowMessage("WM_GETCONTROLNAME");
StringBuilder sb = new StringBuilder(BufferSize);
byte[] ControlName = new byte[BufferSize];
long BytesRead = 0;
IntPtr BytesReadPointer = new IntPtr(BytesRead);
IntPtr OtherMem = IntPtr.Zero;
try
{
OtherMem = VirtualAllocEx(Handle, IntPtr.Zero, new IntPtr(sb.Capacity), AllocationType.Commit, MemoryProtection.ExecuteReadWrite);
var Result = SendMessage(Handle, Message, new IntPtr(sb.Capacity), OtherMem);
//Result contains different numbers which seem like the correct lengths
var Result2 = ReadProcessMemory(Handle, OtherMem, ControlName, BufferSize, out BytesReadPointer);
//ControlName always comes back blank.
}
finally
{
var Result3 = VirtualFreeEx(Handle, OtherMem, BufferSize, FreeType.Release);
}
return ""; // Convert ControlName to a string
}
So after a good night's sleep and a little tinkering, I managed to fix the problem myself. There were two problems. First, I was passing in the handle to the control to VirtualAllocEx. But in the documentation for that function, it says that it takes a handle to the process. So started supplying that. Then VirtualAllocEx was telling me that I had an invalid handle. So it turns out the handle you pass to VirualAllocEx has to have PROCESS_VM_OPERATION set. So I made a call to OpenProcess to get that handle, then passed that to VirtualAllocEx. After that, everything worked. I just had to convert the byte array coming back into a string, and trim a bunch of nulls. This returns the Name property on the controls. I'll post the code here in case anyone else needs something like this.

I am trying to create an app on pebble using MenuLayer. My intention is to create Menu's and then sub-menus using the MenuLayer.
I did some basic implementation using "menu_layer_set_callbacks" method and registering callbacks methods for each submenu layers. However, now I realise its getting too messy.
I want to know if there is any easy way out provided in the framework to meet this requirement.
Thanks.
KK
I don't know what you ended up with, but for my project, I made a set of sub-windows but reuses the same callbacks, you can pass custom data to let each know what type it is. Then just push the required sub-windows as needed
void sub_window_load(Window* parentWindow) {
Layer* window_layer = window_get_root_layer(parentWindow);
const GRect bounds = layer_get_frame(window_layer);
MenuLayer* new_layer = menu_layer_create(bounds);
const int context = *((int*) window_get_user_data(parentWindow));
if (context == ID_A) s_A_layer = new_layer;
else if (context == ID_B) s_B_layer = new_layer;
menu_layer_set_callbacks(new_layer, window_get_user_data(parentWindow), (MenuLayerCallbacks){
.get_num_sections = sub_menu_get_num_sections_callback,
.get_num_rows = sub_menu_get_num_rows_callback
/* etc */
});
menu_layer_set_click_config_onto_window(new_layer, parentWindow);
layer_add_child(window_layer, menu_layer_get_layer(new_layer));
}
void createSubWin(Window** w, int* context) {
*w = window_create();
window_set_user_data(*w, context);
window_set_window_handlers(*w, (WindowHandlers) {
.load = sub_window_load,
.unload = sub_window_unload
});

I need to develop an application in c# that could automatically detect an iPhone when it is connected to the system and read a particular file for the iPhone file system. I basically want this file to be downloaded automatically from device to the PC. I used USBpcap tool that suggests that iTunes connects to phone using some XML format. Any help or insight greatly appreciated. Is there any documentation of Third party APIs that can get me started? There are some applications that can replicate iTunes functionality e.g Copytrans
Is there any protocol or APIs provided by Apple?
I have been digging the internet and found this link Layered communication for iPhone.
Also I am using the LibUsbDotNet libraries for communicating to the usb device(Example). Can any one suggest which EndPoints should be used.
It seems to me that I have to implement usbmuxd in windows application. It is a multilayer protocol. There must be some libraries that implement usbmuxd(I dont think I have to implement the protocol all by my self)
I dont have much idea about iTunes communication as well as USB communication. I am adding as much information as I can(of course with the things I come up with in my R&D). Any help is highly appreciated.

I have been trying to send hello packet bytes to iPhone but I am not able to read any response from phone.
To play with ipod you can use SharePodLib
As I understand it, only one client can use the USB connection to iOS at one time. On both macOS and Windows, that one client is usbmux. That library multiplexes TCP connections with higher-level clients, including iTunes, Photos, and (on macOS) the open-source peertalk library.
So on Windows, you wouldn't want to implement your own usbmux, but rather a client that sits on top of that, analogous to peertalk. I haven't seen anything open-source that does this, but a number of developers have accomplished it with their own proprietary software.
If anybody else has pointers about using usbmux on Windows, I'd love to hear about it.

You can use imobiledevice-net. It provides a C# API to connect to iOS devices using your PC.
For example, to list all iOS devices connected to your PC, you would run something like this:
ReadOnlyCollection<string> udids;
int count = 0;
var idevice = LibiMobileDevice.Instance.iDevice;
var lockdown = LibiMobileDevice.Instance.Lockdown;
var ret = idevice.idevice_get_device_list(out udids, ref count);
if (ret == iDeviceError.NoDevice)
{
// Not actually an error in our case
return;
}
ret.ThrowOnError();
// Get the device name
foreach (var udid in udids)
{
iDeviceHandle deviceHandle;
idevice.idevice_new(out deviceHandle, udid).ThrowOnError();
LockdownClientHandle lockdownHandle;
lockdown.lockdownd_client_new_with_handshake(deviceHandle, out lockdownHandle, "Quamotion").ThrowOnError();
string deviceName;
lockdown.lockdownd_get_device_name(lockdownHandle, out deviceName).ThrowOnError();
deviceHandle.Dispose();
lockdownHandle.Dispose();
}
I am creating a software on Mac and I would like to change the value of an IORegistryEntry. I can view it on the IORegistryExplorer, but I can't edit it. So it's my understanding that I have to edit it via code. Here is my code:
CFMutableDictionaryRef matchingDict = IOServiceNameMatching("AppleUSBMultitouchDriver");
io_service_t service = IOServiceGetMatchingService(kIOMasterPortDefault, matchingDict);
if(service) {
CFStringRef manufacturer = IORegistryEntryCreateCFProperty(service, CFSTR("Manufacturer"), kCFAllocatorDefault,0);
NSLog(#"%#", (NSString*)manufacturer);
kern_return_t err = IORegistryEntrySetCFProperty(service, CFSTR("Manufacturer"), CFSTR("test"));
NSLog(#"error = %d", err);
}
This will output
2010-04-10 16:09:09.015 Test[41548:a0f] Apple Inc.
2010-04-10 16:09:09.015 Test[41548:a0f] error = 0
But after I check the value in the IORegistryExplorer, it still doesn't change. Does anybody have any suggestions?
Thank you
In order for this to be possible, usually the driver for the particular hardware you're changing has to implement setProperties() (in IOKit) that makes this change for you.
It's unlikely that Apple will implement setProperty() in their AppleUSBMultitouchDriver in a way that allows you to change the manufacturer name. They want to specify what kind of fruit they are. ;)
Use IOConnectSetCFProperties instead of IORegistryEntrySetCFProperty. Pass it a dictionary with the settings you want to set.
For example to turn off three finger swipe to navigate, call it with a dictionary containing { TrackpadThreeFingerSwipe = 0; }
This is example how to change trackpad settings properly. Trackpad.prefpane do exactly this, but also save this setting somewhere in defaults (if you will not find out where exactly, ask here about it).
P.S. getEVSHandle() may be found in MachineSettings.framework.
P.P.S. Checked only on 10.5 & 10.6.
NSInteger zero = 0, one = 1;
CFNumberRef _numberWith0 = CFNumberCreate(kCFAllocatorDefault, kCFNumberNSIntegerType, &zero);
CFNumberRef _numberWith1 = CFNumberCreate(kCFAllocatorDefault, kCFNumberNSIntegerType, &one);
CFMutableDictionaryRef propertyDict = CFDictionaryCreateMutable(kCFAllocatorDefault, 1, NULL, NULL);
CFDictionarySetValue(propertyDict, #"TrackpadThreeFingerSwipe", flag ? _numberWith1 : _numberWith0);
io_connect_t connect = getEVSHandle();
if (!connect)
{
// error
}
kern_return_t status = IOConnectSetCFProperties(connect, propertyDict);
if (status != KERN_SUCCESS)
{
//error
}
CFRelease(propertyDict);
