1. Sending instant messages
int SkypeSendInstantMessageW(string skype_name,string message,int status); int SkypeSendInstantMessageA(string skype_name,string message,int status);// 메타트레이더용 4
There are several tests in a function before sending instant message:
- The user name cannot be empty or begin with a number.
- The user with the specified name must be in the contact list.
- The message cannot be an empty string.
- The network status of the recipient must coincide with the specified value.
The list of the network status constants:
constant name | 값 | description |
---|---|---|
STATUS_OFFLINE | 1 | Offline |
STATUS_ONLINE | 2 | Online |
STATUS_AWAY | 4 | Out of place |
STATUS_DONT_DISTURB | 16 | Do not disturb |
To set several allowed statuses simultaneously bit-by-bit addition of constants is used, 예를 들어: STATUS_ONLINE | STATUS_AWAY.
The maximum length of an instant message is ~8000 ANSI symbols, ~4000 Unicode symbols.
The example of a code:
string InpSkypeName = "echo123"; // Skype name string InpTextMessage = "안녕하세요 :)"; // Text message string msg; ENUM_SKYPE_ERROR err=(ENUM_SKYPE_ERROR)SkypeSendInstantMessageW(InpSkypeName,InpTextMessage,STATUS_ONLINE|STATUS_AWAY); 만약에(err==ERROR_NO_ERRORS) msg=StringFormat("Sent IM to %s, %에스",InpSkypeName,InpTextMessage); 또 다른 msg=StringFormat("Error sending IM to %s, 오류: %에스",InpSkypeName,EnumToString(err)); Print(msg);
2. Sending SMS messages
The service to send SMS messages is fee-paid at the moment!
int SkypeSendSmsMessageW(string phone_number, string message); int SkypeSendSmsMessageA(string phone_number, string message);// для MetaTrader 4

- Text message must not be an empty string
Sending SMS to a non existing number is not an error. The cost for this operation will be charged, but returned after a short time, as the actual message wasn't delivered.
The SMS message is limited to 116 ANSI symbols, 58 Unicode symbols.
The example of a code:
input string InpPhoneNumber = "+380123456789"; // Phone number input string InpTextMessage = "안녕하세요 :)"; // Text message string msg; ENUM_SKYPE_ERROR err==(ENUM_SKYPE_ERROR) SkypeSendSmsMessageW(InpPhoneNumber,InpTextMessage); 만약에(err==ERROR_NO_ERRORS) msg=StringFormat("Sent SMS to %s, %에스",InpPhoneNumber,InpTextMessage); 또 다른 msg=StringFormat("Error sending SMS to %s, 오류: %에스",InpPhoneNumber,EnumToString(err)); Print(msg);
