• VB.NET, templates, reflection, inheritance, feeling adrift

  - by brovar

  I've just made myself up a problem and am now wondering how to solve it. To begin with, I'm using some third-party components, including some calendar controls like schedule and timeline. They're used in the project classes more or less like that: Friend Class TimeBasedDataView 'some members End Class Friend Class ScheduleDataView Inherits TimeBasedDataView Public Schedule As Controls.Schedule.Schedule 'and others End Class Friend Class TimeLineDataView Inherits TimeBasedDataView Public TimeLine As Controls.TimeLine.TimeLine 'and others End Class (Hmm, code coloring fail, never mind...) Now, to allow managing the look of data being presented there are some mechanisms including so called Style Managers. A lot of code in them repeats, varying almost only with the control it maintains: Friend Class TimeLineStyleManager Private m_TimeLine As TimeLineDataView Private Sub Whatever() m_TimeLine.TimeLine.SomeProperty = SomeValue End Sub End Class Friend Class ScheduleStyleManager Private m_Schedule As ScheduleDataView Private Sub Whatever() m_Schedule.Schedule.SomeProperty = SomeValue End Sub End Class I was wondering if I could create some base class for those managers, like Friend Class TimeBasedCtrlStyleManagerBase(Of T As TimeBasedDataView) Private m_Control As T 'and others End Class which would unify these two, but I've got lost when it came to maintaining two components that have nothing in common (except their properties' names, etc.). Type reflection maybe? I'll be grateful for any advice ;)

• Drop down menu going under #main div background in IE 7/8/9

  - by Adrift

  Here is the link to the domain http://linenwoods.com I am working on. I am going to fit the navigation list items on the header, but when the drop down menu is implemented I'm pretty sure it'll go under the #main div like you see currently. Is there any easy way fix to this? I couldn't find anything related to this from a google search .. was hoping someone could help me out. Below is the relevant CSS .. I tried playing around with z-index with no luck as I was told IE8 renders it strangely. If you have the time please follow the link with IE and leave a response .. I am trying to be as cross-browser compatible as possible and already am at a pretty pathetic start. Any help would be appreciated :) body { background-image:url('Background1.jpg'); background-position: center; height: 100%; margin: 0; padding: 0; opacity: 0.8; filter: alpha(opacity=80); } #main { width : 1010px; height: 1315px; background-color: white; margin-top: 15px; filter: alpha(opacity=80); } header { width: 1010px; height: 230px; background-color: white; margin: 0 auto; margin-top: 15px; filter: alpha(opacity=80); } footer { width: 1010px; height: 230px; background-color: white; margin: 15px 0 15px 0; filter: alpha(opacity=80); }

• Space partitioning when everything is moving

  - by Roy T.

  Background Together with a friend I'm working on a 2D game that is set in space. To make it as immersive and interactive as possible we want there to be thousands of objects freely floating around, some clustered together, others adrift in empty space. Challenge To unburden the rendering and physics engine we need to implement some sort of spatial partitioning. There are two challenges we have to overcome. The first challenge is that everything is moving so reconstructing/updating the data structure has to be extremely cheap since it will have to be done every frame. The second challenge is the distribution of objects, as said before there might be clusters of objects together and vast bits of empty space and to make it even worse there is no boundary to space. Existing technologies I've looked at existing techniques like BSP-Trees, QuadTrees, kd-Trees and even R-Trees but as far as I can tell these data structures aren't a perfect fit since updating a lot of objects that have moved to other cells is relatively expensive. What I've tried I made the decision that I need a data structure that is more geared toward rapid insertion/update than on giving back the least amount of possible hits given a query. For that purpose I made the cells implicit so each object, given it's position, can calculate in which cell(s) it should be. Then I use a HashMap that maps cell-coordinates to an ArrayList (the contents of the cell). This works fairly well since there is no memory lost on 'empty' cells and its easy to calculate which cells to inspect. However creating all those ArrayLists (worst case N) is expensive and so is growing the HashMap a lot of times (although that is slightly mitigated by giving it a large initial capacity). Problem OK so this works but still isn't very fast. Now I can try to micro-optimize the JAVA code. However I'm not expecting too much of that since the profiler tells me that most time is spent in creating all those objects that I use to store the cells. I'm hoping that there are some other tricks/algorithms out there that make this a lot faster so here is what my ideal data structure looks like: The number one priority is fast updating/reconstructing of the entire data structure Its less important to finely divide the objects into equally sized bins, we can draw a few extra objects and do a few extra collision checks if that means that updating is a little bit faster Memory is not really important (PC game)
