• Game Technologies: DirectX, XNA, XACT, etc. Terrain component source code

  The terrain is split into batches, one batch from every texture type. Each batch has a vertex buffer and an index buffer. It uses quad trees to find which tiles should be rendered. Once it has the list of tiles that are visible it populates the batch's index buffer. I'm sorry for the disgraceful lack of comments in the code, but here you go, a tile-based terrain component implementation for XNA.

• Visual C# Make end of statement ";" optional?

  I think microsoft should make the end of line statement, (i.e. the ";") optional. If you program VB.net like I do and is inevitably forced to write/read C# code, having to write the ; after each statement is annoying. I know C/C++/java etc all have it but in an enviroment like Visual studio where the IDE makes life so much easier the end of line statement is unnecessary. Who agrees with me Daticus wrote: Just look at the express versions of C# and VB, VB has two fold more traffic, which means VB is more popular with up and coming programmers. True (probably, I don't know the actual numbers). However, you're missing the big picture here. Of all the world's programmers, 90+% use some form of Visual Basic (VB.Ne ...Show All

• SQL Server dataset with parameterized top query

  I have a report based on a dataset that has a "top()" statement in it. SELECT TOP (10) name, val FROM tab ORDER BY val DESC I wanted wanted to return a report with 10 rows as the default. But allow the user to change the default and regenerate the report with more rows. I tried the following; SELECT TOP (@N) name, val FROM tab ORDER BY val DESC Normally in VS2005, the paraemeters work fine for things like the WHERE clause. But when i do the TOP(@N) the query/report parameter synchronization messes up. If i manual go to the parameter tab of the dataset and configure the matching between query and report params it works. But doing anything to the dataset resets this. Its getting very tiring. Any advice for a ...Show All

• Windows Forms bindingsource.addnew and .haschanges

  I have a form that loads in a new state, but the user may decide not to add a new row, but will want to edit an existing row. When the form opens with no ID for the form, my code calls: BindingSource.AddNew() Even if no changes are made to the form, calling: DirectCast (BindingSource.DataSource, DataSet).HasChanges() This will always come up as having changed. Is there any way to find if there have actually been any changes after AddNew is called. Mark Dahl Gavin, Thank you for the response. I really appreciate it. However, the following code is run when the form loads: '// Header refresh If FormHelper.DBInt(FormID) > 0 Then EmployeeTableAdapter.Fill( Me .Emplo ...Show All

• SQL Server Performance probelm with large table

  I have a web page to allow user to create Sales Order. For this i have 2 tables, one for the informations (Sales Order) about the order and the other table (Sales Order LineItems ) contains the details of the order. For exemple for one order if i order 2 CD i will have 2 rows for this order in the Sales Order LineItems table. When i've created the page i've made some test by creating 100 orders. Everything was working fine. Now yesterday i've tried to create 100 000 orders and 400 000 details rows. Since i 've created all thoses order the performance are not good at all.
