mobile - Limitations on SMS messages sent using free email->SMS gateways -

-

In the United States, many cell (mobile) phone providers have an email gateway for SMS, which allows anyone to send an email that will be

Send a text message For example, to send a text message to a user who has a Verizon phone, you can send an email to user_phone_number@vtext.com.

But ... how reliable are these entrances, and at which rate can the message be sent? At some point, what is the provider block or throttle service?

Email-to-SMS gateways are generally reliable in some situations (read below). Whether you should use an email-to-SMS gateway or an actual third-party provider, depending on the application . If you need a lot of control over the formatting of the messages, collecting the answers, then go with a third-party provider. If you are sending a lot of messages from the same email address, then the messages will be backed up. For example, I sent a message to about 3,000 AT & T wireless recipients, and some received messages for up to 3 days, but generally sending 10-30 minutes would not be a problem.

I emailed to that iPhone application SMS had been using Gateway that I made. It sends about 10 messages per minute for all US carriers, and it may take a seldom problems.

There are three main issues I run with email via SMS gateway:

  • You do not have control when appearing like a message. Each carrier is different for some, the recipient will show the email address and show the other names. Some include the subject line of email, nothing happens.
  • You can not control the incoming number of messages. Fortunately, the general population usually reads all the text messages
  • You can not control the answer without the server-side script to handle the incoming email. For most carriers, a reply from the phone goes back to the sender's email address.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
