What's in your derived functions?<br />
Do you simply pass control back to the base class ::Open() and ::CanAppend()?

Hi<br />
<br />
I have a CRecordset derived class which I have added a new method too, to enable<br />
records to be added in my own custom way.<br />
<br />
When I try and call <br />
<br />
if(!Open()) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Open the Project recordset<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return FALSE;<br />
if(!CanAppend()) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// check we can add to the recordset object<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return FALSE; <br />
<br />
I get an exception. It seems that MFC doesn;t like these methods to be called from<br />
within the derived CRecordset class. <br />
<br />
Does anyone know any different, or a way of calling these functions from within<br />
the dervived class??<br />
<br />
<br />
Thanks in advance<br />

CRecordset functions

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
