<div>Hi ,</div>
<div> </div>
<div>Thanks for the mail Frank.</div>
<div> </div>
<div>The problem is rightly pointed. In my case the dataset (poDataset) is not getting created at times (parameters being the same) . I have checked thoroughly everything related to this, but did not find any either solution or problem.</div>
<div> </div>
<div>I would appreciate if you can assist me solving this issue.</div>
<div> </div>
<div>Regards,</div>

If the dataset creation fails, a null pointer will be returned<br>and GetRasterBand() will fail - possibly crashing.<br><br>Best regards,<br><font color="#888888">--<br>---------------------------------------+--------------------------------------<br>
