CreateFromFile of COleClientItem fail

[MKC002]

I want to preview doc file using CreateFromFile of COleClientItem.Tis method takes COleDocument object as argument. Sometimes CreateFromFile success and i can see the preview but sometimes it's fail for same file. I did not understand the reason why. Can someone guide me? Is there any memory problem? Also if i have office 2003 installed at my system and to open ofice 2007 file i installed utility provided by microsoft. Using CreateFromFile if i want to preview office 2007 file then CreateFromFile failed. But in some cases it's succeed and i see the file name in preview contents.How to see the actual contents? Should i use any other function in this case.

I used CoInitialize(NULL) and AfxEnableControlContainer(); in InitInstance. Is there something else which i sould do

[Hans Dietrich]

Try calling AfxOleInit() in InitInstance.
