Hi hans,
I already found some problems in v2.4.1 and fixed it. A new hotfix will be released within one or two days.
Sorry if I’m opening a old issue again. It seems that I have the same problem with v3.0.4
Object reference not set to an instance of an object.

in separate assembly I have the following code :
public void Load(byte[] datastream)
{
System.IO.MemoryStream memoryFile = new MemoryStream(datastream);
excelFile.Open(memoryFile);
Initialize();
}
And I have an upload.asp which should load the uploaded file into the Excel object
The followig is just a small piece of the code
<upload.aspx>
fileLength = uploadedFile.ContentLength;
byte[] dataStream = new byte[fileLength];
uploadedFile.InputStream.Read(dataStream,0,fileLength);
// load xls file as datastream
uploadParser.Load(dataStream);
</upload.aspx>
and I checked in debug mode, the datastream isn’t empty. I can save the object called memoryFile to a xls file again. (did that in another test.)
oeps… ignore this one.
I already found the error. Forgot to initialize the Aspose.Excel.Excel object
