• Visual C# C#, VB6 or Borland C++

  Hello all, I am part of a team of a new company, and we are fighting on what language to use. What are the advantages of C# over all the others. I need hard arguments to make them use C#. Thanks If you're having to fight to use C# over VB6 or Borland C++ then I'd recommend leaving the company and working for a company where you don't have to waste so much time. You can say that one of the big advantages of C# and .NET is that it's very easy to accommodate modern versions of the other two languages you mentioned (VB.NET and C++/CLI) once you're working in the .NET framework.

• Smart Device Development WM 5.0 + VS2005 + SQL Mobile Problem.

  Good morning. A few people in here have helped me out with various noob questions I've popped out while developing my first Mobile app. Now I seem to have hit a major stumbling block. I've been scouring the net for several days trying to find an answer but I can't seem to make sense of the wealth of information. (The abbreviated gist of my post is - "Why can't I run SqlCe classes under Windows Mobile 5.0 and Visual Studio 2005 ") The story is this: * I developed the app using VS2003 and CF 1.0, succesfully deploying it to a Windows Mobile 2003 SE device. The app used SQL CE 2.0 as part of its operation. * The device we have been given now (Symbol MC70) which will be the production model has just been catastrophically diagnosed as ...Show All

• Software Development for Windows Vista tableadapter update inside failed transactionscope doesn't rollback the datatable

  I have a number of tableadapters which must update under one transaction. After a transaction failure I notice that the data in the (SQL Server 2005) database has rolled back but the data in the datatables on the middle tier has not. This creates problems as some of the tables contain data on which other data tables are dependent. In particular, identity fields on these datatables are left populated with the identity from the failed insert. Is there a way to accomplish a rollback of data in these datatables without resorting to datatable.clear() followed by datatable.Add[tablename]row Regards. All the work that gets done against the DataTables (inside DataSets) is accessed through methods ...Show All
