• Aditya.P DataTable.Select() Question

  I've searched high and low for an answer to this, but all I can find is stuff about the filter/sort bug, so hopefully someone can help me. I want a distinct list of instruments where the date is the first date where the instrument has data. Ignore the possibility of null values. Normally I would write this is SQL: Select ValueDate, Instrument, Price where Instrument = '0001' and ValueDate = (select min(ValueDate) where Instrument = '0001') For some reason I just can't get this to work, no matter how many variations I use. I hope I'm missing something terribly obvious. Thanks in advance, James If you are using DataTable.Select(), you can simply achieve what you want by using strFilter ...Show All

• Dan Heile Type of File

  Hi Guys, How can I extract the information of a file like 'Type of File' ex. Type of File: Microsoft Excel Worksheet. I am able to extract the other information like Last Access..using FileInfo.

• itznfb Accessing XML files via network shares

  Hi; Note: While our specific use is ASP.NET, this is a general "accessing XML" question. Our ASP.NET application allows a user to give it an XML filename and the app then opens that file as a datasource to generate a report. The issue we face is we do not want the file opened using the credentials of the user that our ASP.NET app is running under for two reasons: The ASP.NET user may not have access to \\hr\payroll\salaries.xml but the person requesting the report does. The ASP.NET does have access to Web.Config but the person requesting the report does not. Our app supports both forms and WindowsIdentity as an authtication/authorization method. So we do not have the client identity to use if they are using ...Show All

• Jamie Thomson store a file into a database and retrive it

  hi I want to store my generated xml files into a database and then retrive some of them. my data type in sql server database is Image. my algorithm works OK with images but when I try to store xml files I miss a few characters from the end of the retrived xml file. and for some heavier xml files have the same problem with some rubbish characters attached to the end of the file. what's going on file is a file. if my algorithm had problem it shouldn't work with Images either. SQL expects an image column to be binary, an xml file is not binary, it is text utf* . You should not really insert text into a binray field, you should insert it into a text/xml field.

• Giulio-G Is an assembly the only possible target for an emitted method?

  I am wondering if there is any way to emit a method and its supporting metadata without having to create a full-fledged assembly I want to be able to emit individual methods on the fly and feel that it's rather heavy handed to create a whole assembly just for one method. What I would ideally like to do is emit the byte codes into a buffer that is part of another data structure and then pass that buffer's adress along with a pointer to appropriate metadata (which could contain metadata for multiple methods and data types) to a function that will jit-compile the method and execute it. Is there an interface that will let me do this -- that will let me separate the metadata I point to from the acutal executable byte code and submit them in se ...Show All
