• Visual Basic Not Declared Issue With Visual Studio 2005

  Hi there! Recently installed the Visual Studio 2005 180-day-trial to see what it runs like and so-far I like, except I've encountered a rather show-stopping issue. I created a ASP.NET project, added a DropDownList Webcontrol to the page using the Design view, hopped into the Code view and happily wrote the code to connect to the database, create a new datatable from a db table and bind the results to the DropDownList. It worked perfectly and I was very happy. A few compiles later and the IDE says: 'Error "ddl_artists" is not declared'. Hmmm. I thought, checked the code and sure enough the variables were 'intellisensed'. I hadn't deleted the declarations. After a few minutes of pondering, I added Dim ddl_artists As System.Web.UI.W ...Show All

• SQL Server Is it reasonable that a table has 240 fields

  Hi, I have 240 sensors to sample one time per second,then store the data in sql server. Is it reasonable that the table has 240 fields If do,it will generate about 70,000 records every day.One month records will be 2,100,000.

Which method is better,or who can give me another better method or some suggestions. I need your help.Thank a lot. Yes,most of fields should be filled.

• Visual Studio Team System Custom Policy for Non-C# Code

  Our project is currently using TFS for some .NET based projects. We will soon be starting new projects using other technologies, such as Oracle PL/SQL, Java, HTML,etc. We will continue using a single tool for our source code control, i.e. TFS, even though some of the new projects will be developed by tools other than Visual Studio. We would like to make use of the code analysis policy to verify the quality of code being checked-in. However the existing code analysis policy is for C/C# code. My questions: (1) Are there existing policies developed for other languages, e.g. HTML, Javascript, PL/SQL, etc (2) If not, how does one go about developing these policies Thanks, Si. Hi: I do not think we have an ...Show All

• .NET Development C# ListBox Glitch

  Hi, I'm using VS .NET 2003. I have a list box and a user can add a file and it will read through the file and add each line to the listbox using: ListBox.Items.Add(theString); That part works fine. The problem is I set the list box to allow the user to select multiple items so those selected items can be removed. When I load just one file, it removes the correct selected items, but when I load two it doesn't remove every item that was selected. I've tested it in detail printing out everything it did and realised the 'aListBox.SelectedItem' method wasn't working correctly. Say when 5 items were selected the SelectedItem method said only 3 items were selected. Anyone know how I could possibley fix this problem without disabling multiple sel ...Show All

• .NET Development what is shim?

  This term is new to me. What does it mean Thanks Sure, you could use P/Invoke to call the native function. But that's error prone and not very OOP. You'll have to use a wrapper (shim) if you try to re-use a native C++ class, .NET cannot instantiate them. You can write a wrapper without P/Invoke if you use the C++ compiler. ...Show All
