1. Sending instant messages

整数 SkypeSendInstantMessageW(弦 skype_name,弦 message,整数 status);
整数 SkypeSendInstantMessageA(弦 skype_name,弦 message,整数 status);// メタトレーダー用 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	価値	description
STATUS_OFFLINE	1	Offline
STATUS_ONLINE	2	オンライン
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, 例えば: STATUS_ONLINE | STATUS_AWAY.

The maximum length of an instant message is ~8000 ANSI symbols, ~4000 Unicode symbols.

The example of a code:

弦 InpSkypeName     =  "echo123";        // Skype name
弦 InpTextMessage   =  "こんにちは :)";       // メール

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

もしも(err==ERROR_NO_ERRORS) msg=文字列形式("Sent IM to %s, %s",InpSkypeName,InpTextMessage);
それ以外 msg=文字列形式("Error sending IM to %s, エラー: %s",InpSkypeName,EnumToString(err));

2. Sending SMS messages

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

整数 SkypeSendSmsMessageW(弦 phone_number, 弦 message);
整数 SkypeSendSmsMessageA(弦 phone_number, 弦 message);// для MetaTrader 4

入力 弦 InpPhoneNumber   =  "+380123456789";  // Phone number
入力 弦 InpTextMessage   =  "こんにちは :)";       // メール

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

もしも(err==ERROR_NO_ERRORS) msg=文字列形式("Sent SMS to %s, %s",InpPhoneNumber,InpTextMessage);
