send

I am writing a class in Java which is used to greatly simplify the process of multicasting. However, I am having two big problems with it: The class sends data (I can verify this with my net monitor, Wireshark) but the data is not received by any others in the same group. On some machines, the sending packet TTL is exceeded in transit (again, according to Wireshark). Could anyone please help me? I've been trying and searching for answers for hours, and it appears that my code follows all of the basic procedures for connecting to, joining, sending, and receiving data from a multicast host.

I'm building a distributed web server in C/MPI and it seems like point-to-point communication completely stops working after the first MPI_BARRIER in my code. Standard C code works after the barrier, so I know that each of the threads makes it through the barrier. Point-to-point communication also works just fine before the barrier. However, when I copy-paste the same code that worked the line before the barrier into the line after the barrier it stops working entirely. The SEND will just wait forever. When I try using an ISEND instead, it makes it through the line, but the message is never

I want to send a simple message and i have <uses-permission android:name="android.permission.SEND_SMS"/> in my manifest, but I always get: java.lang.SecurityException: Sending SMS message: uid 10064 does not have android.permission.SEND_SMS. I checked this answer , but it still doesn't work. this is my manifest: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.roa.sendsms" > <uses-permission android:name="android.permission.SEND_SMS"/> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label

I am new to VC++ and programming. I have to write code to send a email in VC++. How do I go about it? Please help!! Here's how I do it with the ATL classes. I think you need one of the paid versions of VC++ to get ATL. You will need the name of your email server. CSMTPConnection smtp; if (!smtp.Connect(m_strEmailServer)) return false; // start generating the email message; remember to call CoInitialize somewhere in the app before this CMimeMessage msg; msg.SetSubject(m_strSubject); msg.SetSender(m_strSender); // repeat the following as necessary msg.AddRecipient(strSingleRecipient); msg

I working on a form whereby when the user enter in their email account and click on send, an email will be sent to their email account. I have everything worked out. Just that it doesnt send the email to my account. Anyone have any ideas? Is there a configuration that I left out or something? This is the sample from my controller: public function retrieveemailAction(){ $users = new Users(); $email = $_POST['email']; $view = Zend_Registry::get('view'); if($users->checkEmail($_POST['email'])) { // The Subject $subject = "Email Test"; // The message $message = "this is a test"; // Send email //
