<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Ramiro,<br><br>You can use the OGRLayer::TestCapability() method to check write capability of a layer. However, there are going to be errors if another process accesses the files in the mean while.<br>
<br>When ogr2ogr is executed with -append, -overwrite or --update options, it should error out with the message "Unable to open existing output datasource" if a file cannot be opened to write. Can you raise a new ticket [1] describing this problem?<br>

<br>I want to overwrite a shapefile using ogr(c++). If the dbf file in the destination shapefile is already open by anather program(exel), the operation fails in the middle and only the shp and shx files are updated.<br>
How could I check, using OGR, if the dbf(or any other file in the shapefile) is blocked before I overwrite it? <br><br>I tested this with "ogr2ogr -overwrite destination source.shp" and the same thing happens <br>
