• Visual Studio VS2005 fails to build solution

  I'm having a strange problem where the VS2005 Beta 2 IDE fails to build my projects. The setup is at follow: 1 Solution with 2 projects all located in the same folder.

• .NET Development the performance of DataTable.Merge() in ADO.NET 2.0

  Dear Sirs,       I have see ideas at         http://msdn.microsoft.com/msdnmag/issues/05/11/DataPoints/default.aspx and I have a question about the performance of DataTable.Merge().     It seems in ADO.NET 2.0 this method executes with increasing time when DataTable has more data rows, while merging about 10 rows each time. The table I used as follow,     DataSet ds=new  DataSet();     DataRow dr;     ds.Tables.Add("BigTable");     ds.Tables[0].Columns.Add("ID", Typ ...Show All

• SQL Server Metadata driven SSIS

    I am looking for some pointers on Metadata driven SSIS.   Specifically, how to automate creation of a large number of packages in SSIS using metadata.   I am looking at this as a solution to deploy multiple packages on multiple servers. Any other ideas on this would be highly appreciated.   Thanks   Vishal Verma By the way, I think what Suresh may be talking about here is that we're doing some work to identify and promulgate best practices around metadata for IS that will be released as either a KB article or whitepaper. That is supposed to be available around the time ...Show All

• .NET Development Encrypting the app.config file

  My application will use the DataProtectionConfigurationProvider to encrypt my app.config file. I can encrypt the file from within my applicaiton, but I would like to be able to encrypt it outside the application so that the file is encrypted when it is deployed. I know that you can encrypt web.config files with aspnet_regiis.exe. Is there a tool that can encrypt app.config files as well Eric No there is currently no tool available to encrypt your app.config automagically...well at least to my knowledge so don't quote me on that.

• Visual C# Future C# string optimization directions

  This is a topic of academic interest to me.  Are there any plans to optimize code patterns such as: string results = ...; bool foundSomething = results.ToLower().Contains( "something" ) ) Here, I'm making a case-insensitive search and it seems that ToLower() is an unnecessary use of CPU cycles and memory accesses.  One possible solution, which isn't very extensible, is for ToLower() to do a lazy-copy: it will first make a reference to the input string and add a "use-lower-case" bit.  Contains() uses this bit to do the case-insensitive compare on the original string.  Brian ...Show All
