          <p>
            <var>TDBCustomNavigator</var> is the parent class for 
<var>TDBNavigator</var>, an advanced tool for navigating through datasets held locally in response to a query sent to the database. Most of the important properties are defined here.</p>
          <p>It consists of a series of toolbuttons to move to the <b>First</b>, <b>Prior</b>, <b>Next</b> or <b>Last</b> record; to <b>Insert</b> or <b>Delete</b> a record; to <b>Edit</b> a record (enter Edit mode), to <b>Post</b> the changes. to <b>Cance</b>l the changes, and to <var>Refresh</var> the display from the database. The set of buttons for display can be customised in <var>VisibleButtons</var>, which allows display of individual buttons to be suppressed</p>
          <p>If used in conjunction with a DataAware control such as <var>TDBGrid</var> or <var>TDBMemo</var> it controls which records are displayed , the position of the record selection cursor, and the initiation of changes to the dataset and ultimately the database.</p>
          <p>Most of the functionality of the toolbar is already built-in to the control, but if the programmer needs to specify actions to be associated with individual buttons, there is a procedure  <var>BtnClick</var> to which an argument can be sent with the index value of the button clicked, and the procedure chooses which action to call dependent on the button index.</p>
          <p>The <var>DataSource</var> property must be set to link to the appropriate set of data.</p>

            <var>TDBNavigator</var> is an advanced tool for navigating through datasets held locally in response to a query sent to the database.</p>
          <p>It consists of a series of toolbuttons to move to the <b>First</b>, <b>Prior</b>, <b>Next</b> or <b>Last</b> record; to <b>Insert</b> or <b>Delete</b> a record; to <b>Edit</b> a record (enter Edit mode), to <b>Post</b> the changes. to <b>Cancel</b> the changes, and to <b>Refresh</b> the display from the database.</p>
          <p>The programmer may determine, at design time, which buttons are to be displayed or suppressed by adjusting the <var>VisibleButtons</var> property in the Object Inspector.</p>
          <p>If used in conjunction with a DataAware control such as <link id="#lcl.DBGrids.TDBGrid">TDBGrid</link> or <link id="TDBMemo">TDBMemo</link> it controls which records are displayed , the position of the record selection cursor, and the initiation of changes to the dataset and ultimately the database.</p>
          <p>Most of the functionality of the toolbar is already built-in to the control, but if the programmer needs to specify actions to be associated with individual buttons, there is a procedure <link id="TDBCustomNavigator.BtnClick">TDBCustomNavigator.BtnClick</link> to which an argument can be sent with the <var>Index</var> value of the button clicked, and the procedure chooses which action to call dependent on the button index.</p>
          <p>The <var>DataSource</var> property must be set to link to the appropriate set of data.</p>

          <p>
            <var>HowToUseDataAwareControls</var> - Hints for accessing databases. A set of Data-Aware components is provided, to make it easier to access information held in databases.</p>
          <p>Before using Data-Aware components, it is necessary to make a connection with a database, and this should be done either using a TSQLConnection or a TDBf component, depending on the type of database that is being used. In any case, the components for connection with the database need to be found in $Lazdir/components/sqldb/, $Lazdir/components/tdbf/ or whatever other source is appropriate. They need to be added using the <var>Components</var> Menu Item of the IDE, and compiled ready for adding. The IDE needs to be re-built to include the new components.</p>
          <p>To make the connection with the database: first place a <var>DataBase Connection</var> on the Form (invisible at run-time, so put it anywhere convenient); set its properties to connect the user (with name and password) to the appropriate server, database and table (the connection component should deal with all the user-authentication issues, opening and closing the database etc). Then put on a <var>TDataSource</var> from the Data Access tab of the Component Palette, and perhaps items such as <var>TSQLTransaction</var> and <var>TSQLQuery</var>, depending on the particular database you are using. The various database components need to be linked to each other, for example by setting the <var>Transaction</var> property of a database connector to the appropriate transaction component, and linking the <var>DataBase</var> property of the Transaction component back to the database connector; link the DataSource's <var>DataSet</var> property to the appropriate SQLQuery or other set of data, and its <var>Transaction</var> property to the transaction component</p>
          <p>Each Data-Aware control (on the Data Controls tab of the Component Palette) has the usual set of properties to determine its shape and size, position, colour and font etc. But there are also special properties to define the data to be displayed or modified. These include the <var>DataSource</var> property which must be set to link to the defined set of data, and often a <var>Field</var> component to determine which of the columns in the database is to be displayed. </p>
          <p>Most of the components operate on a single Row or record of the database, but the <var>TDBGrid</var> is capable of displaying and operating on multiple rows and columns, in a <var>StringGrid</var> format, allowing the user to get an overview of what is in the database. The DBGrid will display the contents of the DataSet even at design time, provided the various components are enabled or rendered active; this allows the designer to ensure that all the connections to the database have been correctly made.</p>
          <p>The <var>TDBNavigator</var> component is used in conjunction with the Data-Aware components. It consists of a series of buttons to allow browsing through the DataSet, displaying the first, previous, next or last record (or Row), inserting or deleting records, committing the changes back to the database or refreshing the DataSet from the database.</p>
          <p>The way database programming works is typically as follows:</p>
          <ul>
            <li>a database is opened for access by the user (Database Connection)</li>
            <li>a command is issued (eg by <var>TSQLQuery</var>) to select or extract some or all of the records which are then stored locally in the <var>DataSet</var>
            </li>
            <li>the contents of the <var>DataSet</var> are acted on by the Data-Aware components, displaying one Row or record at a time from selected Columns, or perhaps the whole DataSet in a <var>DBGrid</var>, editing records, inserting or deleting records, or using the data to perform statistical tests or calculations</li>
            <li>at intervals usually prescribed by the user (sometimes after every change, sometimes after a whole series of changes), the contents of the local DataSet are sent back to the database, causing an update of the database's contents. This process is referred to as 'Commit' or 'Post' or sometimes as 'Update'</li>
          </ul>
          <p>The programmer can determine which events are associated with a Commit action by supplying suitable event handlers for <var>OnClick</var>, <var>OnChange</var>, <var>OnFinishedEdit</var> etc.</p>

    <element name="TDBImage.WriteHeader"><short>Write a header in the image stream.</short><descr><p>The <var>WriteHeader</var> property controls whether or not a header will be written to the image stream. By default a header will be written. This helps to efficiently identify the image format when loading. The writing of a header in the image stream could be a problem if the database will be shared with external applications that do not expect a header in the image stream. In this case, set WriteHeader value to false in order to skip the header writing.
</p><p>The default value is true.</p><p>Note: The <var>WriteHeader</var> value is ignored if <var>OnDbImageWrite</var> event is implemented.

      </element><element name="TDBImage.OnDBImageRead"><short>Event to read a custom header from image stream.</short><descr><p>By default, the <var>TDbImage</var> component expects a header at the start of the image stream. This helps to efficiently identify the image format contained in the data stream. On writing, the header is controlled by the <var>WriteHeader</var> property or the <var>OnDbImageWrite</var> event handler.</p><p>When loading image data which was created by external applications, the data stream may not have a header or the header is not a format identifier that the <var>TDbImage</var> component would recognize.</p><p>In this case, the <var>OnDbImageRead</var> event can be used to identify the image format in the data stream. In the <var>GraphExt</var> parameter it must return a format identifier corresponding to the registered image format. This format identifier could e.g. be read from the data stream provided in the <var>s</var> parameter. On return, the data stream should start with the raw image data.</p><p>If the <var>OnDbImageRead</var> handler was not implemented or if it returns an invalid format identifier, the <var>TDbImage</var> component will try to load the image by checking the data stream content. This means that it is not necessary to write an <var>OnDbImageRead</var> event handler for the most common image formats, For example: jpg, png, gif or bmp.</p><p>The <var>TDbImage</var> component will be able to identify the image format even if the data stream doesn't have a header for those TGraphic registered classes that implement the IsStreamFormatSupported method.</p>

      </element><element name="TDBImage.OnDBImageWrite"><short>Event to write a custom header into image stream.</short><descr><p>Use <var>OnDBImageWrite</var> to write a custom header in the image stream. This header could be "decoded" in the handler for the <var>OnDbImageRead</var> event when loading. The header will be followed by the image raw data.</p><p>By default, <var>TDbImage</var> will write an image header in order to efficiently identify the image format when loading. This behaviour is controlled by the <var>WriteHeader</var> property. If your database will be shared with external applications that do not support this, it is important to not write an image header. This could be achieved by writing an empty handler for <var>OnDbImageWrite</var>. Note that an empty handler has the same effect as setting <var>WriteHeader</var> to false.</p><p><var>OnDbImageWrite</var> has precedence over the <var>WriteHeader</var> property.</p>
