  string cur_drive = c2.const2 ( ); // this is just the current drive ("D:") string pathq = cur_drive + " \\VFP_Projects\\Data\\Stoxx\\ " + symbol + ".csv"; File.Delete ( pathq ); using ( StreamWriter sw = new StreamWriter ( pathq ) ) { sw.Write ( response ); sw.Close ( ); } response is a string variable that contains a whole *.csv file downloaded from Yahoo.

I have to look into the file and repeat the operation which is a great inconvenience. Is there a way to improve performance Why does it happen How can I get a feedback as to th ...Show All

• SQL Server error when connect to sqlserver from another machine

  hi .. i install sqlserver and make app with vb6 using ADO to connect to the database and successfully i put that application on another pc on the network when i open it it says "can't login computername\guest" !! any help thanks in advance. It's hard to describe "domain controller" and related stuff in short words. I recommend you find some documents related to Windows Networks to read. Are you sure your client is running under the user account you created and you used that account to login to the server It means you may need to login the client Windows system and run your client app under that account. If you user Administrator or even logon the computer without a user/password, it won't work. ...Show All

• Software Development for Windows Vista Reasoning behind CardSpace's secure desktop

  The CardSpace's secure desktop is displayed in order to submit your card. I don't fully understand the reasoning behind the decision to disallow interaction with the desktop while selecting and submitting a card. Can anyone explain this What I'm most interesting in, is the fact that there is a Firefox Identity Selector plug in available at http://www.xmldap.org/ . This plugin, being based on Java, does not lock up the desktop. So, given that there may be valid reasons for having a secure desktop for identity selection, would that mean that any non-Microsoft identity selection solution will be 'sub-optimal' One of the advantages of building an identity selector for a particular Operating System is ...Show All

• Architecture dataSet Vs DataReader

  Hi All, I have one question regarding implementing data reader and dataset in my project. My project is a windows application with the database in a separate server. I have numerous records to be retrieved and processed.My application has many master data tables and has many transaction tables too. Is it a good approach to frequently hit database server to get the data using datareader or to get the data using dataset with minimal round trips. Which is good approach Please advice me on this. Thanks in advance. I agree that it depends on the scenario. Certainly if the data is being directly serialized into a different format then using datasets makes no sense. Also if you are just using the data for a mom ...Show All
