Data Strings
The data string holds address information. The first part of a data string consists of a series of keyname= value elements separated by semicolons (;). You can include optional user data by putting a number sign (#) after the last value, followed by an application-defined string.
The key name is a lowercase string that identifies the data and implicitly indicates what type of data is contained in the value. For instance, the "provider" key name indicates that the value contains a Microsoft® DirectPlay® service provider globally unique identifier (GUID), in the form of a GUID string. The following characters are reserved and should not be used in value strings.
| Ampersand (&) | Forward slash (/) |
| At sign (@) | Number sign (#) |
| Colon (:) | Question mark (?) |
| Equal sign (=) | Semicolon (;) |
The first element in the data string must be the provider. Other elements can follow in any order. A generic URL looks something like this.
x-directplay:/provider=Provider_GUID;[keyname1=value1];[keyname2=value2][...]#[user defined string]
The Provider_GUID should be of the form
{EBFE7BA0-628D-11D2-AE0F-006097B01411}
but using the escape characters for the invalid characters as shown in the following example.
%7BEBFE7BA0-628D-11D2-AE0F-006097B01411%7D
