How can I read HRESULTS

[francisco]

I find it a little dumm but I can´t not read an HRESULT as a <br>char value. For example, I have a function as <br><br>HRESULT Myfunction()<br><br>Which tries to make something, it has DI_OK return values for succes and different DIERR_... to describe errors, I would like to call Myfunction and then with a TRACE call perform an error description:<br><br>HRESULT hr;<br>hr=Myfunction();<br>TRACE(Something to return hr as a character);<br><br>Thank in advance<br><br><br>javi

javi,

Perhaps I am missing the point of your question, but I'll try to answer it as I understand it.

An HRESULT is just a long integer. If all you want is the value, you could use ltoa to convert it to an ascii value and then trace out

I have a feeling what you want is the &quot;hex&quot; representation of the HRESULT, in which case all you need to do is to set up a character buffer and sprintf the HRESULT into it using %lx as the format specification.

Or if you want to get fancy, you could set up a quick switch statement based on the HRESULT and using the text descriptions for the errors that you will find in dinput.h.

Hope this helps!
