-  <!-- 

-    Microsoft ResX Schema 

-    

-    Version 2.0

-    

-    The primary goals of this format is to allow a simple XML format 

-    that is mostly human readable. The generation and parsing of the 

-    various data types are done through the TypeConverter classes 

-    associated with the data types.

-    

-    Example:

-    

-    ... ado.net/XML headers & schema ...

-    <resheader name="resmimetype">text/microsoft-resx</resheader>

-    <resheader name="version">2.0</resheader>

-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>

-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>

-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>

-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>

-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">

-        <value>[base64 mime encoded serialized .NET Framework object]</value>

-    </data>

-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">

-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>

-        <comment>This is a comment</comment>

-    </data>

-                

-    There are any number of "resheader" rows that contain simple 

-    name/value pairs.

-    

-    Each data row contains a name, and value. The row also contains a 

-    type or mimetype. Type corresponds to a .NET class that support 

-    text/value conversion through the TypeConverter architecture. 

-    Classes that don't support this are serialized and stored with the 

-    mimetype set.

-    

-    The mimetype is used for serialized objects, and tells the 

-    ResXResourceReader how to depersist the object. This is currently not 

-    extensible. For a given mimetype the value must be set accordingly:

-    

-    Note - application/x-microsoft.net.object.binary.base64 is the format 

-    that the ResXResourceWriter will generate, however the reader can 

-    read any of the formats listed below.

-    

-    mimetype: application/x-microsoft.net.object.binary.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter

-            : and then encoded with base64 encoding.

-    

-    mimetype: application/x-microsoft.net.object.soap.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter

-            : and then encoded with base64 encoding.

-

-    mimetype: application/x-microsoft.net.object.bytearray.base64

-    value   : The object must be serialized into a byte array 

-            : using a System.ComponentModel.TypeConverter

-            : and then encoded with base64 encoding.

-    There are any number of "resheader" rows that contain simple 

-    name/value pairs.

-    

-    Each data row contains a name, and value. The row also contains a 

-    type or mimetype. Type corresponds to a .NET class that support 

-    text/value conversion through the TypeConverter architecture. 

-    Classes that don't support this are serialized and stored with the 

-    mimetype set.

-    

-    The mimetype is used for serialized objects, and tells the 

-    ResXResourceReader how to depersist the object. This is currently not 

-    extensible. For a given mimetype the value must be set accordingly:

-    

-    Note - application/x-microsoft.net.object.binary.base64 is the format 

-    that the ResXResourceWriter will generate, however the reader can 

-    read any of the formats listed below.

-    

-    mimetype: application/x-microsoft.net.object.binary.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter

-            : and then encoded with base64 encoding.

-    

-    mimetype: application/x-microsoft.net.object.soap.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter

-            : and then encoded with base64 encoding.

-

-    mimetype: application/x-microsoft.net.object.bytearray.base64

-    value   : The object must be serialized into a byte array 

-            : using a System.ComponentModel.TypeConverter

-            : and then encoded with base64 encoding.

-    The primary goals of this format is to allow a simple XML format 

-    that is mostly human readable. The generation and parsing of the 

-    various data types are done through the TypeConverter classes 

-    associated with the data types.

-    ... ado.net/XML headers & schema ...

-    <resheader name="resmimetype">text/microsoft-resx</resheader>

-    <resheader name="version">2.0</resheader>

-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>

-        <comment>This is a comment</comment>

-  <!-- 

-    Microsoft ResX Schema 

-    

-    Version 2.0

-    

-    The primary goals of this format is to allow a simple XML format 

-    that is mostly human readable. The generation and parsing of the 

-    various data types are done through the TypeConverter classes 

-    associated with the data types.

-    

-    Example:

-    

-    ... ado.net/XML headers & schema ...

-    <resheader name="resmimetype">text/microsoft-resx</resheader>

-    <resheader name="version">2.0</resheader>

-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>

-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>

-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>

-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>

-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">

-        <value>[base64 mime encoded serialized .NET Framework object]</value>

-    </data>

-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">

-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>

-        <comment>This is a comment</comment>

-    </data>

-                

-    There are any number of "resheader" rows that contain simple 

-    name/value pairs.

-    

-    Each data row contains a name, and value. The row also contains a 

-    type or mimetype. Type corresponds to a .NET class that support 

-    text/value conversion through the TypeConverter architecture. 

-    Classes that don't support this are serialized and stored with the 

-    mimetype set.

-    

-    The mimetype is used for serialized objects, and tells the 

-    ResXResourceReader how to depersist the object. This is currently not 

-    extensible. For a given mimetype the value must be set accordingly:

-    

-    Note - application/x-microsoft.net.object.binary.base64 is the format 

-    that the ResXResourceWriter will generate, however the reader can 

-    read any of the formats listed below.

-    

-    mimetype: application/x-microsoft.net.object.binary.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter

-            : and then encoded with base64 encoding.

-    

-    mimetype: application/x-microsoft.net.object.soap.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter

-            : and then encoded with base64 encoding.

-

-    mimetype: application/x-microsoft.net.object.bytearray.base64

-    value   : The object must be serialized into a byte array 

-            : using a System.ComponentModel.TypeConverter

-            : and then encoded with base64 encoding.

-    various data types are done through the TypeConverter classes 

-    associated with the data types.

-    

-    Example:

-    

-    ... ado.net/XML headers & schema ...

-    <resheader name="resmimetype">text/microsoft-resx</resheader>

-    <resheader name="version">2.0</resheader>

-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>

-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>

-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>

-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>

-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">

-        <value>[base64 mime encoded serialized .NET Framework object]</value>

-    </data>

-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">

-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>

-        <comment>This is a comment</comment>

-    </data>

-                

-    There are any number of "resheader" rows that contain simple 

-    name/value pairs.

-    

-    Each data row contains a name, and value. The row also contains a 

-    type or mimetype. Type corresponds to a .NET class that support 

-    text/value conversion through the TypeConverter architecture. 

-    Classes that don't support this are serialized and stored with the 

-    mimetype set.

-    

-    The mimetype is used for serialized objects, and tells the 

-    ResXResourceReader how to depersist the object. This is currently not 

-    extensible. For a given mimetype the value must be set accordingly:

-    

-    Note - application/x-microsoft.net.object.binary.base64 is the format 

-    that the ResXResourceWriter will generate, however the reader can 

-    read any of the formats listed below.

-    

-    mimetype: application/x-microsoft.net.object.binary.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter

-            : and then encoded with base64 encoding.

-    

-    mimetype: application/x-microsoft.net.object.soap.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter

-            : and then encoded with base64 encoding.

-

-    mimetype: application/x-microsoft.net.object.bytearray.base64

-    value   : The object must be serialized into a byte array 

-            : using a System.ComponentModel.TypeConverter

-            : and then encoded with base64 encoding.

-    Microsoft ResX Schema 

-    

-    Version 2.0

-    

-    The primary goals of this format is to allow a simple XML format 

-    that is mostly human readable. The generation and parsing of the 

-    various data types are done through the TypeConverter classes 

-    associated with the data types.

-    

-    Example:

-    

-    ... ado.net/XML headers & schema ...

-    <resheader name="resmimetype">text/microsoft-resx</resheader>

-    <resheader name="version">2.0</resheader>

-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>

-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>

-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>

-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>

-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">

-        <value>[base64 mime encoded serialized .NET Framework object]</value>

-    </data>

-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">

-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>

-        <comment>This is a comment</comment>

-    </data>

-                

-    There are any number of "resheader" rows that contain simple 

-    name/value pairs.

-    

-    Each data row contains a name, and value. The row also contains a 

-    type or mimetype. Type corresponds to a .NET class that support 

-    text/value conversion through the TypeConverter architecture. 

-    Classes that don't support this are serialized and stored with the 

-    mimetype set.

-    

-    The mimetype is used for serialized objects, and tells the 

-    ResXResourceReader how to depersist the object. This is currently not 

-    extensible. For a given mimetype the value must be set accordingly:

-    

-    Note - application/x-microsoft.net.object.binary.base64 is the format 

-    that the ResXResourceWriter will generate, however the reader can 

-    read any of the formats listed below.

-    

-    mimetype: application/x-microsoft.net.object.binary.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter

-            : and then encoded with base64 encoding.

-    

-    mimetype: application/x-microsoft.net.object.soap.base64

-    value   : The object must be serialized with 

-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter

-            : and then encoded with base64 encoding.

-

-    mimetype: application/x-microsoft.net.object.bytearray.base64

-    value   : The object must be serialized into a byte array 

-            : using a System.ComponentModel.TypeConverter

-            : and then encoded with base64 encoding.
