Cant solve it!! DSOFile.dll error: The name is not valid. 0x800300FC (STG_E_INVALIDNAME)

Question

User-431313886 posted

Hello. I am using the DSOFile.OleDocumentPropertiesClass to read the author property of all files in a directory. It works perfectly on my machine, and another development server, but when I try it on our SQA server, I get this error:

Exception:The name is not valid. (Exception from HRESULT: 0x800300FC (STG_E_INVALIDNAME)) File:\\eng-dev1\xxx_WebSite2\Projects\xxx2.0xxx\xxxatingWorksheet.xls

I have been trying to solve this issue for a couple days now and I get the error every time.

Is there somthing special I need to do to the path before giving it to the Open method in the OleDocumentPropertiesClass? Does it need to be unicode? I know the error code is actually "The name %s is not valid" so that %s is being replaced by an empty string maybe... really need help with this one. This is the code I have. Basically the Open call throws an error.

DSOFile.OleDocumentPropertiesClass oleProps = new DSOFile.OleDocumentPropertiesClass();

DSOFile.SummaryProperties summary;

oleProps.Open(fi.FullName, true, DSOFile.dsoFileOpenOptions.dsoOptionOpenReadOnlyIfNoWriteAccess);

summary = oleProps.SummaryProperties;

last_saved = (DateTime)summary.DateLastSaved;

Thanks for your time.

you need to put a @ before the filename

  docDSO.Open(@"C:\test.doc", false, DSOFile.dsoFileOpenOptions.dsoOptionOpenReadOnlyIfNoWriteAccess);
