• .NET Development Cache invalidation

  When using Asp.Net caching API, if cached items has the same priority, what algorithm is used to decide what items to be removed from cache to release some memory space I am also looking at the Enterprise Librarchy Caching block, the online documentation mentioned that: The onus of the items that need to be scavenged is placed on the BackGroundScheduler object. The BackGroundScheduler performs a: major sort on priority minor sort on LTA Does anybody know what LTA is Thank you Thank you very much for your answer. Is last time access actually the same thing with LRU(Least Recently Used) From my understanding, I can't see the difference. Please correct me if I am wrong. Thank you ...Show All

• Windows Forms Validate DataGridView Cells.

  Hello, I am currently using a DataGridView on a WindowsForm, for entering data into an Access Database. Data are entered into the database programmatically when a submit button is clicked. Data insertion in the database works just fine. The problem is the cells validation when i press the Submit button. I'll explain what i mean. So far i have utilized the datagrid _CellValidating event for validation but this works only when i click and edit a cell. If i don't click a cell and i just bypass it, the cell will contain an incorrect value (null or empty string) and this will cause problems later when i click the submit button. Is there any way i can validate the whole datagridview cells when i click the submit button Than ...Show All

• SharePoint Products and Technologies SharePoint error when editing documents with custom content types

  Hi, We have these weird problems with standard MOSS workflows. We've created some publishing pages in the Pages document library using custom content types with al sort of site columns (about 20+). Now, when we attach a standard approval workflow to the list and start it manually, everything is ok and the workflow is started.

• Visual Basic ComboBox and Messge

  How do you pass a name from a ComboBox list to a variable and then give a message in a message box via a Select Case Statement i.e Case 1 - meesage 1 Case 2 - message 2 etc etc. Ta you don't need to store the item selected in a variable then based on that do a case statement. You can totally avoid this step and just get the Text chosen from the combobox and do your case statements. http://msdn.microsoft.com/library/default.asp url=/library/en-us/vblr7/html/vastmselectcase.asp Example: Select Case Me.theComboBox.Text Case " Bob " MessageBox.Show("Your name is Bob") Case " Jim " MessageBox.Show("Your name is Jim") end select you can of cour ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. drawing order for multiple passes

  I'm porting a MDX project to XNA, and have found a problem. In MDX, when drawing using a multi-pass technique, the scene first is drawn using the first pass, then using the second pass and so on. In XNA, I have the impression that first, the first object is drawn using pass1, pass2, etc. When the first object has been drawn, the second object is drawn. Summarized: MDX: (foreach pass: draw all objects) XNA: (foreach object: draw using all passes) In more detail, the XNA case would be (foreach triangle : draw using all passes). The screens I get quite convince me of this, and if you want I can post some code and some screenshots of both cases. But first I would like to ask if there is some kind of way to instruct XNA to (foreach pas ...Show All

• Windows Live Developer Forums Draw Circle on Map?

  Hello, I would like to draw a circle on a Virtual Earth v3 map, based on the user clicking a point and dragging a radius. I've seen some of the "background search" topics on this forum, but none seem to deal with doing this in Javascript with the map control. Can this be done Thanks, -Mike I started messing around a bit with this. The best I could come up with (and I think this would be an IE-only solution) would be to trap the onclick and mousemove locations (so you know where the center is and what the radius length is), and then draw your own circle using VML. I did something like this: function AddCircle() { var el = document.createElement("div"); el.innerHTML = "< ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Input for fighting game

  Hello, I have been working on a sort of fighting game and now i don't know how to do the Input. It's a windows game so I use keyboard input. What i need is A for punching and W for kicking preceded by a left/up/right/down key to make different punches/kicks. So first tap one of the arrow keys and then tap A/W to make a move. ((If no arrow key is pressed do a default punch)). How can i do this I tried a lot but I don't know how to recogneize which combination keys the user tapped. greets jeroen.
