New Post: Saving large workbooks

I have the same problem :(

MemoryStream WriteToStream()

{
    //Write the stream data of workbook to the root directory
    MemoryStream file = new MemoryStream();
    hssfworkbook.Write(file);
    return file;
}

generate the error in the line:

 hssfworkbook.Write(file);

constructs the workbook but in the moment of make the write... failure!!

no way I finished building the excel?
