• .NET Development Complex SELECT query

  Hi All, I have a query regarding the optimisation of a "SELECT" query. The probem is that there is a table having 1,00,000 of records. I have to make a "SELECT" query on them and display them in a datagrid as a report. The problem here is that i am using simple "SELECT" (SELECT * from tablename) query. and it is taking too much time. is there any optimize way so that the query will execute in less time. Thanks in advance Select * is slower than using the column names. Sounds like you need to add or tweak your table indexes. Are you sure the lag is in sql It can take a long time to load that many rows in a grid. ...Show All

• .NET Development Newbie: script runs on local but not networked drive??

  Hi all, Newbie question - I want to create a script/executable to copy files from a subdirctory, and then update the copied ("local") versions with the current timestamp. The only way I could figure out the timestamp issue, was to actually write over the local copy's contents, then save it. See code at bottom of message. Now maybe there's a better way to do that - but that's not my question. (Note: code implies you have a subdirectory called "SubDir", and it contains a readable text file called "myfile.txt".) I can compile the code (using jsc), and run the executable on my C drive and everything's fine. Now I move the whole directory/subdirectory tree somewhere else on my C drive, and everything's still fine ' ...Show All

• Architecture Typed Dataset or Custom Classes

  Hey friends, I am a VB developer, soon I am going to start a new project. It will be a client application, I will use a SQL server database. I am used to use custom classes, I create my onw variables properties, events and methods. I am aware of the Typed Data Set and thinking about using it on my new project. The problem is that  I have never used it,  I do not know the minuses and plusses of the Typed dataset. Now, my boss and me on the desicion phase, we want to implement the most efficient and easy maintainable one. If you ask me , I'm quite happy with custom classes :)) My opinion is that the custom class is better for performance purposses, because I  create properties and meth ...Show All

• SQL Server Disk activity

• .NET Development Memory Issues

  Hello all, I've been trying to profile my ASP.NET application on my application server. I set up 2 counters for aspnet_wp process namely '#bytes in all heaps' and 'process:private bytes'. According to a documentation that i read, '#bytes in all heaps' should be less that 'process: private bytes'. However the '#bytes in all heaps' was far greater than that of the 'process: private bytes'. I'm lead to believe that this indicates a memory leak somewhere. Now, the problem is that i've got 15 ASP.NET applications running on that server and i need to find which application(s) are causing the problem. Please i'll need help on which counters to set up that will enable me pin point the rouge application. Thanks Emeka. ...Show All
