messages

I have a question about events in .NET (C#). I have had to write code for several situations in which I have a background task running and I want to notify a main thread, or controller class, that something has occurred, such as task completed, or finished copying a file, but I don't want the background task to wait for the main thread's delegate to process the event. I want to do something like message passing: Send the message, but who cares what they do with it. For example: A class is written to process several processes in sequence, one after the other. Each process needs to run on a

Is there a way to retrieve all Facebook Message ids with the read_mailbox permission and then delete them all one by one? Everyone is crying about how it's difficult to delete your chat/message history. Wondered if there was an easy way to write an app to do this. http://developers.facebook.com/docs/reference/api/message/ Normally you would issue an HTTP DELETE call to https://graph.facebook.com/messageID?access_token= ... But it appears that this is an API call that either require special whitelisting from Facebook or isn't currently supported because it does not work right now and returns

I'm somewhat confused and wondering if I've been misinformed, in a separate post I was told "New threads are only created when you make them explicitly. C++ programs are by default single threaded." When I open my program that doesn't explicitly create new threads in ollydbg I noticed multiple times that there are often 2 threads running. I wanted to understand how the message loop works without stopping up execution, the explanation I got was very insufficient at explaining how it works. Does the message loop create a new thread or does it take up the main thread? If it takes the main thread

i have an input component that has three types of validation (required,validatorMessage,converterMessage) and this input has its own message icon, and the whole form has a messages component to display all the messages for all components as follows: <p:message for="idEstNumOfUser" display="icon" id="msgEstNumOfUser" /> <p:inputText id="idEstNumOfUser" placeholder="Estimated Number of Users" value="#{mybean.estimatedUserCount}" required="true" requiredMessage="" maxlength="8" title="Estimated Number of Users" validatorMessage="Please enter digits only for 'Estimated Number of Users'"

I'm looking for suggestions about choosing a portable way to achieve local IPC in a robust way, since i'm new to C++ and would like to avoid common pitfalls of fiddling with shared memory and locks; therefore I was thinking about message-passing style ipc. I was planning to use qt for other reasons anyway, thus i took a peek to Qt ipc options. if i understand correctly qt doesn't offer a completely portable message-passing ipc feature. it can use d-bus, but using it on windows would be a problem. other ways are limited to embedded linux platforms (and i would like to port this thing to AIX). I

Here is a portion of my struts.xml: <constant name="struts.custom.i18n.resources" value="global" /> and <action name="picture_save" method="pictureSave" class="PictureActionBean"> <interceptor-ref name="fileUpload"> <param name="maximumSize"> 2097152 </param> <param name="allowedTypes"> image/bmp,image/gif,image/jpeg,image/jpg,image/png </param> </interceptor-ref> <interceptor-ref name="defaultStack"></interceptor-ref> <result name="success" type="redirect">picture</result> <result name="error">error</result> </action> My global.properties file is stored directly in src/ and it contains this:

I'm trying to use js-ctypes in Firefox to receive USB media/drive notifications, but I'm having a few issues and I can't tell if it's because I'm very inexperienced at Win32 API or awful at js-ctypes (or both!) I've started by adapting an example I found on Alexandre Poirot's blog: Blog Entry Full JS Source That example uses js-ctypes to create a "message-only" window, and then interacts with the shell service for the purpose of communicating with the Windows notification tray. It seems simple enough, so after some research on the merits of RegisterDeviceNotification vs SHChangeNotifyRegister

SignalR loses many messages when I transfer chunks of bytes from client over server to client (or client to server; or server to client). I read the file into a stream and sent it over a hub or persistent connection to other client. This runs very fast, but there are always messages dropped or lost. How can I transfer large files (in chunks or not) from client to client without losing messages? As @dfowler points out, it's not the right technology for the job. What I would recommend doing is sending a message that there is a file to be downloaded that includes the link and then you can

What is the Message that matches the TextChanged property in .NET for C++\Win32? Assuming you're talking about the Edit control , EN_CHANGE is the notification you're looking for. The parent of the Edit control receives the notification via the WM_COMMAND message, with HIWORD(wParam) == EN_CHANGE , LOWORD(wParam) == edit control identifier and lParam == edit control HWND . 来源： https://stackoverflow.com/questions/3435730/edit-control-text-changed-message-in-c-win32
