messages

问题 Will it be possible to suppress messages such as "Using date format..." when using a function like? > ymd(vec) Using date format %Y%m%d Whilst these are good to see when you are casting a vector, it can be annoying in some circumstances. 回答1: Looking at the ymd code, it callse parse_date , which gives those annoying messages via the command message . Looking at ?message , there is a corresponding suppressMessages : suppressMessages(ymd(x)) (Note - other similar functions are suppressWarnings

问题 I have a text area inside a tab of accordion panel which is a description. I am trying to edit a description and saving it. I am validating the text area so that max character shouldn't exceed 1000 character. I am using <p:message> to display validation message.

问题 I've created a custom message type for use in resizing my Window , called WM_NEED_RESIZE . I've defined it in my .h file, and initialized in my .cpp file. I have also registered my WindowProc function to accept messages. Here is the code for these items: const uint32 WindowsGLWindow::WM_NEED_RESIZE = WM_USER + 100; LONG WINAPI WindowsGLWindow::WindowProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam) { static PAINTSTRUCT ps;// do I need this? static sint32 newWidth = 0; static sint32

问题 I wish to build my own application which can send keyboard commands(messages) to the Windows OS. For example when I press the combination ctrl+shift+n, I wish to launch the notepad.exe . How can I do that? Do you have some advice for me about the concept used. I've read that is possible when are used keyboard hooks? That's the only way? Do you know a free and open-source application which does this as simple is possible? 回答1: Your particular example can be done without any programming at all,

问题 i need to know when my application recieves a WM_SETTINGCHANGE message (formerly known as WM_WININICHANGE). Problem is that the message pump in TApplication sends it down a black hole (default handler) before i can get a chance to see it: procedure TApplication.WndProc(var Message: TMessage); ... begin Message.Result := 0; for I := 0 to FWindowHooks.Count - 1 do if TWindowHook(FWindowHooks[I]^)(Message) then Exit; CheckIniChange(Message); with Message do case Msg of WM_SETTINGCHANGE: begin

问题 First of all: Is this even possible? I have a third party dll that interfaces some hardware. It's written in MFC. I received (from the dll vendors) a sample Visual Studio 2010 solution which has only one project: An MFC application (.exe) which calls the third party dll in question. It works fine. When I try to use the third party dll from my dll (which is plain C++, no MFC, no .NET), I can call its functions fine, but there's a catch: the sample MFC app seems to "override" MessageProc in

问题 I am sending a normal message through a producer to RabbitMQ and then I send a second message with the expiration attribute assigned to a value. Then using the rabbitmqctl list_queues command I monitor the status of the messages. I found that if I send a normal message first and then a message with expiration , the rabbitmqctl list_queues is always showing me 2 messages pending on the queue. When I consume them, I get only one. On the other hand if I send just 1 message with expiration , in

问题 I am looking for a message broker (like Apache ActiveMQ for Java) that works with PHP, preferably open-source. Any ideas? 回答1: You can use Stomp (http://stomp.codehaus.org), it has a client for PHP that you can use to communicate with any of the brokers (includes ActiveMQ, http://stomp.codehaus.org/Brokers). There's also Memcacheq (http://memcachedb.org/memcacheq/), there's an example about how to use it on that page. You could also use Apache ActiveMQ and use a library like Zend_Queue (part

问题 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

问题 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/ 回答1: 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
