<concept id="GUID-23A60DE7-B72D-41BD-9F1E-882D31A7E3C7" xml:lang="en"><title>Required
resource file statements</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>As noted in <xref href="GUID-EC49B54F-7724-433B-BD7F-201DE3B7DAA6.dita">Resource
file structure</xref>,
if the <parmname>NAME</parmname> is given, it must be the first statement
in the resource file.</p>
<p>After the <parmname>NAME</parmname> statement, resource files must begin
with the following three <parmname>RESOURCE</parmname> statements: </p>
<ul>
<li><p><parmname>RESOURCE RSS_SIGNATURE</parmname></p></li>
<li><p><parmname>RESOURCE TBUF</parmname></p></li>
<li><p><parmname>RESOURCE TBUF RESOURCE EIK_APP_INFO</parmname></p>
</li>
</ul>
<section id="GUID-4283E4EE-4553-4684-B19E-E22BA3248A72"><title>RESOURCE RSS_SIGNATURE</title>
<p>The <parmname>RSS_SIGNATURE</parmname> resource is used to declare the
version number of the resource file. Leave this blank. The syntax is as follows:</p>
<codeblock id="GUID-AA3B4D8C-55DA-4328-82D9-42F1A7BD18F6" xml:space="preserve">RESOURCE RSS_SIGNATURE
{
signature = value
}</codeblock>
<p>where signature is a <parmname>LONG</parmname> value.</p>
<p>By default the signature is set to 0.</p>
<p>For an example, see <xref href="GUID-6AD1DA34-EA3D-4EC9-A667-390507B4D6CB.dita">helloworldbasic.rss</xref>.</p>
<p>For more information on RSS_STRUCTURE, see <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-resource/bafl/BA_RSS_SIGNATUREStruct.html#BA_RSS_SIGNATURE" format="application/java-archive">BA_RSS_SIGNATURE</xref>.</p>

<section id="GUID-CB1C2A65-73EA-4130-923C-AABA2878D93F"><title>RESOURCE TBUF</title>
<p>The <parmname>TBUF</parmname> resource may be used to declare a file
name for use by the document class if it is stated that the <parmname>StoreL</parmname> and <parmname>RestoreL</parmname> of
the document class is called. Otherwise, it may be left blank. The syntax
is as follows:</p>
<codeblock id="GUID-79FD4FE0-2D55-4090-B342-FDFA288DC0A5" xml:space="preserve">RESOURCE TBUF
{
buf="NAME";
}</codeblock>
<p>where <parmname>buf</parmname> is one non-zero terminating string.</p>
<p>For an example, see <xref href="GUID-6AD1DA34-EA3D-4EC9-A667-390507B4D6CB.dita">helloworldbasic.rss</xref>.</p>
<p>Note that the TBUF structure is declared in <parmname>badef.rh</parmname>,
which is included in the <parmname>uikon.rh</parmname> file. For more information
on the TBUF resource, see  <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-resource/bafl/TBUFStruct.html#TBUF" format="application/java-archive"><parmname>TBUF</parmname></xref>.</p>

<section id="GUID-3687D483-9834-401B-B389-6C615B60AB87"><title>RESOURCE EIK_APP_INFO</title>
<p>The <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-resource/uikon/EIK_APP_INFO.html#EIK_APP_INFO" format="application/java-archive"><parmname>EIK_APP_INFO</parmname></xref> resource defines the objects
used in the application GUI. Note that not all possible objects need to be
declared. The syntax is as follows:</p>
<codeblock id="GUID-7930019A-52B6-449F-861C-81EE003A2DB2" xml:space="preserve">RESOURCE EIK_APP_INFO
{
menubar = value2;
cba = value5;
status_pane = value6;
}</codeblock>
<p>where:</p>
<ul>
<li><p><parmname>menubar</parmname> defines the menubar resource</p>
</li>
<li><p><parmname>cba</parmname> defines the softkeys resource</p>
</li>
<li><p><parmname>status_pane</parmname> defines the status pane
resource</p></li>
</ul>
<p>All values refer to resources defined either in the resource file or
in a generated resource header file (<parmname>.rsg</parmname>) included in
the resource file. Note that if an element is not defined, then it is not
used. For example:</p>
<codeblock id="GUID-52146026-2265-43B2-BD2D-B3589CA7E9A9" xml:space="preserve">RESOURCE EIK_APP_INFO
{
menubar=r_name4;
cba=R_AVKON_SOFTKEYS_OPTIONS_EXIT;
}</codeblock>
<p>sets the application to use the menu bar defined by the <parmname>RESOURCE</parmname> statement
with the name<parmname>r_name4</parmname>, and creates the softkey options <parmname>Options</parmname> and <parmname>Exit</parmname> in
the control button area. </p>
<p>For an example, see <xref href="GUID-6AD1DA34-EA3D-4EC9-A667-390507B4D6CB.dita">helloworldbasic.rss</xref>.</p>

the Symbian platform, see <xref href="GUID-CBB00F6A-CBA7-4872-B0A1-A86A863725F5.dita">Precompiled
