1. Sending instant messages

int यहाँ SkypeSendInstantMessageW(string skype_name,string message,int यहाँ status);
int यहाँ SkypeSendInstantMessageA(string skype_name,string message,int यहाँ status);// for MetaTrader 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	कीमत	description
STATUS_OFFLINE	1	Offline
STATUS_ONLINE	2	ऑनलाइन
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, उदाहरण के लिए: 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   =  "नमस्ते :)";       // Text message

string msg;
ENUM_SKYPE_ERROR err=(ENUM_SKYPE_ERROR)SkypeSendInstantMessageW(InpSkypeName,InpTextMessage,STATUS_ONLINE|STATUS_AWAY);

अगर(err==ERROR_NO_ERRORS) msg=स्ट्रिंगफॉर्मेट("Sent IM to %s, %एस",InpSkypeName,InpTextMessage);
else msg=स्ट्रिंगफॉर्मेट("Error sending IM to %s, गलती: %एस",InpSkypeName,EnumToString(err));

Print(msg);

2. Sending SMS messages

The service to send SMS messages is fee-paid at the moment!

int यहाँ SkypeSendSmsMessageW(string phone_number, string message);
int यहाँ SkypeSendSmsMessageA(string phone_number, string message);// для MetaTrader 4

There are several tests before sending SMS message:

• The telephone number must be specified in the international format: + [country code] [city or network code] [telephone number]
• The length of the string which contains the telephone number must be at least 7 symbols and start with a '+' sign
• 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:

इनपुट string InpPhoneNumber   =  "+380123456789";  // Phone number
इनपुट string InpTextMessage   =  "नमस्ते :)";       // Text message

string msg;
ENUM_SKYPE_ERROR err==(ENUM_SKYPE_ERROR) SkypeSendSmsMessageW(InpPhoneNumber,InpTextMessage);

अगर(err==ERROR_NO_ERRORS) msg=स्ट्रिंगफॉर्मेट("Sent SMS to %s, %एस",InpPhoneNumber,InpTextMessage);
else msg=स्ट्रिंगफॉर्मेट("Error sending SMS to %s, गलती: %एस",InpPhoneNumber,EnumToString(err));
