<P>Hi, </P>
<P>I want to take a test about&nbsp;the&nbsp;capability&nbsp;of creation and deletion&nbsp;for all&nbsp;supported formats of ogr .</P>
<P>The code&nbsp;like below,&nbsp; The parameter&nbsp;"const char" are copied from api doc. But&nbsp;all flag return a value of 0, why ?&nbsp;&nbsp;&nbsp;</P>
<P>&nbsp;&nbsp;int flag;</P>
<P>&nbsp;&nbsp;flag=poDriver-&gt;TestCapability("ODrCCreateDataSource");<BR>&nbsp;&nbsp;if(flag==TRUE)<BR>&nbsp;&nbsp;&nbsp;cout&lt;&lt;endl&lt;&lt;"&nbsp; --Supported Creation. "&lt;&lt;endl;<BR>&nbsp;&nbsp;flag=poDriver-&gt;TestCapability("ODrCDeleteDataSource");<BR>&nbsp;&nbsp;if(flag==TRUE)<BR>&nbsp;&nbsp;&nbsp;cout&lt;&lt;endl&lt;&lt;"&nbsp; --Supported Deletion. "&lt;&lt;endl;</P>
<P>Many funcions need const char * params, is there a list of these values ?</P>
