• Game Technologies: DirectX, XNA, XACT, etc. texture coordinates

  The stupidest question..whats worse, Ive had the answer somewhere, but just cannot remember the link or how to do it. Ok, so here's the problem. I have a tileset - basically isometrci tiles of size 45px wide and 46px high. Now, having a gazzillion of textures with one sprite each is just stupid(talking 3D here), so I'm packing lots of tiles into one texture. No problem here, theyre made to fit together nicely, and its all going well. Now, say i have a 64x64 textre(im oversimplyfying it, just for the sake of the example), and one 45x46 tile on it, located in the left corner. Now, im trying to draw an isometric map..How well, basically defining tilted squares and mappig the texture to them. THe problem comes up when the texture is drawn - it ...Show All

• Software Development for Windows Vista LogonUser returns ERROR_PASSWORD_MUST_CHANGE

  Hello I use Logon user to get logon token and run some code with specified user rights (impersonate). If account password is expired, LogonUser returns flase and GetLastError returns ERROR_PASSWORD_MUST_CHANGE. Help me please - is it possible to change Windows user password from my code using some Windows API functions Thank you. I don't think that there is a workaraound. I'd expect that changing an expired password must not work without administrative privileges. If this would work, the entire password expiry thing would be useless. ...Show All

• Visual C# DateTimePicker.ValueChanged event

  I am trying to build some code in this event. The idea is to open an ODBC table and populate a DataGridView with a limited subset. All records in the table are dated and the grid will contain records (schedule) for one date only. The problem I have is that if I go back a few months then every time I change the month with the tool button on the top (the left one) the event fires and the date I get is not the one I need. E.g. today is 10/06/2006 and I need to select 01/25/2006. Then on my first click it will fire with the date 09/06/2006, then 08/06/2006 etc... then finally on 1/06/2006 and after I selected 01/25/2006 in January I will get my date. In the meantime the gridView will get updated needlessly. MouseDown event does not fire ...Show All

• SQL Server Single source, multiple lookups against same table

  Let's say I have 4 columns coming from my OLE DB source. Column1 Column2 Column3 Column4 I also have a table that I'll be using in a lookup, LUPTable. In LUPTable, I have two fields, LUPField, ReplaceField. In my data flow, I need to take columns, 2-4, and look them up against LUPField in LUPTable. I then need to add the value of ReplaceField (when a match is found) into the data flow. The problem that I'm running into is that I don't want to sequentially do the lookups in the dataflow, because that's just a waste of time/memory. I only need to build the in-memory lookup table once, because that exact same data (it is static, for the most part) will be used for the remaining lookups. What is the best way to achieve this The goal is to hav ...Show All

• Visual C# parsing the news websites

  how should i parse only the news from the html contents of any news websites using C#. Please give me the coding or algo. it should be generalize for all websites Such code does not exist. Please, write it and share it. I would be extremely interested to see how it is done. I'm sure there will be quite a bit of AI in there, and that's always been an interest of mine. However, you could try to parse a lot of RSS feeds to get the news. That's really your only option, unless you want to write separate code for each news site. ...Show All
