  I've noticed that XInput v1.3 now provides keyboard support. Not yet tested this on the Xbox360 (October XDK) with my USB keyboard, however I was wondering if the version present in DirectX9.0c for Windows supports the standard keyboards as an active device If so, how do I set it as an XInput device If not, then could you see about providing support to provide adding devices that would ordinarily be accessed using DirectInput ...Show All

• Architecture database watcher ... need suggestions !!

  Hi all, i'm trying to develope a windows service which will listen on a database table (Oracle database) , when a record updated ,the service will store it on another database . (Sql Server database) the question is what is the best methodology to detect database update my idea is to run a query periodically and check the update is anyone have a better solution thanks. If you want to catch every version then you will need to use a trigger on the Oracle to post it into another table (which could be inside SQL Server). If you only run a query periodically then you may not catch every version. This will effect performance. However if you don't need to have every version and only want updates every hal ...Show All

• Windows Forms Duplicate component name 'iDKontaDataGridViewTextBoxColumn'. Component names must be unique and case-insensitive.

  This is the error, which makes me cry. Everytime i work with datagridview, it makes this error in time. I remove every problematic Columns, but it doesnt work. It seems that designer sees something that no longer exists . For instance iDKontaDataGridViewTextBoxColumn was removed from the designer part of the class. ANd designer still says, that it is there. What may be the sollution of this I would like to continue my work without removing whole tab pages of my forms. Please help. Tnanx for every help. The .resx file can be kind of misleading. It defaults the filter to Images, and unless you've got any buttons with images on them you won't see anything initially in the .resx file. Make sure you change the Filter from "Images ...Show All

• SQL Server Restricting Date Parameter Values

  Would like to restrict the dates users can put as parameters. For example, I have a report showing all orders in year 2007. I have exposed Start Date and End Date parameters. When users click the 'View Report' button, the report will filter for orders where attribute EnteredDate is >= Start Date and <= End Date. I want to restrict the users from entering a start date greater than today's date. Would also like to restrict them from entering an end date that is less than the start date parameter. How can I do this TIA. ElSalsero Sure, this could be a workaround. However, your original question was how to restrict the users to enter wrong days.

• SQL Server Mapping a string field to Boolean output in SELECT clause

  Hello, I am facing a problem in a SELECT clause which i cannot solve. In my SQL table ("myTable") i have a few columns ("Column1", "Column2", "TypeColumn"). When I select different columns of the table, instead of getting the value of TypeColumn, i would like to get a boolean indicating whether its value is a certain string or not. For example, the TypeColumn accepts only a number of selected strings: "AAA", "BBB", "CCC". when i do a select query on the table, instead of asking for TypeColumn i would like to ask a boolean value of 1 if TypeColumn is "AAA" and 0 if TypeColumn is "BBB" or "CCC". Also, i would like to make this query while I am ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Lines and curves in 3D

  I am looking for a way to draw lines in 3d space using shaders and xna, but so far my search on the internet have been unsuccesful. I want to duplicate the functionality of the Line-class from MDX 1.1, and basically have the option to draw ie an array of vector3's, but with the option of controlling the width. My (so far not so developed) understanding of shaders have gotten me to the point of rendering linestrips with 1px width using a simple shader, but I need more. What I have found out in my search, is that the lines will probably have to be rendered using screen aligned sprites, positioned along the "curve" of the array of vector's. SpriteBatch does not seem to be able to help me do this, unless I somehow come up with eac ...Show All
