Excel file problem in C#

Question

Hi All, I have an excel file which is stored in the DB2 blob field. My client application, which is a windows application, will connect to this database and download this excel file from the database. If I try to open this excel file I am getting the following exception " cannot be accessed. The file may be read-only, or you may be trying to access a read-only location. Or, the server the document is stored on may not be responding.". If I open the original excel file, which I have inserted into the database, is opening without any problem. I am getting this strange exception for only some specific file. Not for all. Anybody has any information/ideas to solve this problme. Thanks, Gopal
