If I need to pass an integer it's pretty straightforward: User32.INSTANCE.PostMessage(hwnd, WM_MOUSEMOVE, new W32API.WPARAM(), new W32API.LPARAM(x | y << 16)) but how do I get WPARAM out of W32API.HDC for example? ...
I'm writing a service (say, service.com) that provides a REST API to external apps running inside of IFrames. (These apps are hosted from domains outside the service.com). I'm planning a javascript client library for the apps to make pure-javascript requests to the service.com REST API -- basically using postMessage and some ad-hoc en...
Is there any good tool out there that allows developers to correctly debug messages sent between windows with postMessage? Or maybe a plugin for Firebug? Thanks! ...
I'm trying to accomplish this in Win32, but I'm sure the same rules apply in the world of WinForms. Q: I create my main window, and then, when it is being shown, I want to show a modal dialog. The problem is; how can I know when the main window is completely initialized and visible? That is, exactly when is the best time to show the dia...
The documentation for postMessage implies that cross-domain messaging is possible. However: // When the popup has fully loaded, if not blocked by a popup blocker That isn't a very clear note of how to actually do it. In the meantime, I have created two websites: Parent hosted on qc-a.nfshost.com Child hosted on qc-b.quadhome.com ...
What is the equivalent of PostMessage/SendMessage in Windows on Mac OS X? I have recently started out with Mac development, with most of my experience coming from Windows and nix. I want to hook a window and simulate mouse clicks or keyboard presses. Also I want to be able to find a function like GetWindowText or any function that can ...
Hey, I am trying to type a message into notepad without having to have it as my focus window (Foreground Window). This is what I have so far: const UInt32 WM_KEYDOWN = 0x0100; const int VK_F5 = 0x74; [DllImport("user32.dll")] static extern bool PostMessage(IntPtr hWnd, UInt32 Msg, int wParam, int lParam); [STAThrea...
I have to execute some code in the context of the main thread. I am using Lazarus + FPC. I receive an event from a thread inside a DLL (shared library if on linux) and my callback function gets called. Note that this function is not a member of any class but a standalone traditional function with a "cdecl" directive attached. I have to ...
I have a C++/MFC application I need to restructure. The app used to process most of the data on the main thread, therefore blocking the input, and now I want to change it so, that all GUI updates are done through PostMessage. Unfortunately, I can't seem to find a good source on how to achieve this goal. Right now I'm thinking of creati...
I'm aware of the hacks using hash tags, however, I need bi-directional communication with larger payloads and higher throughput. Are there any Flash/ActiveX/etc options that make this possible? ...
As an amateur to anything lower than VB/VBS (C++ WINAPI is a nightmare for someone of my experience) I have no idea how to go about constructing the long lParam for a simple KEYDOWN message in C++ and have probably spent more time looking for a decent explanation than is worth, would someone be able to describe exactly how to go about th...
