• Game Technologies: DirectX, XNA, XACT, etc. How Use DirectX Draw a 2D Polygon which have a hole?

  In C# We can Use SetClip() To draw 2d polygon which have a hole, But In Direct It's seem very hard to complete. If the hole is defined mathematically, you can use pixel shaders to clip() pixels that you don't want rendered. If it's defined by an artist, texturing is probably the way to go, combined with alpha blending or alphakill. ...Show All

• Visual Studio Express Editions you must have a license to use this activex control

  I'm very new to C# so this is probably a simple thing. I am working on a project that uses an activex control and some other third party dlls. Whenever I click on the main form window I get an error telling me I must have a license to use this activex control. Of course, I do have the license but it isn't doing it's trick. Some background.... The sample source I'm working on was created in an earlier version of visual studio. The sample was "upgraded" when I loaded it. The sample does compile and run just fine but I can't edit the main form because of the error. I'm using visual studio 2005 express for C#. ...Show All

• SQL Server Creating an SRS Report

  We've been developing in .NET for some time now, and I'm currently working on a large project which uses a mixture of VB.Net and C#.Net objects. I'm considering the use of SRS instead of Crystal Reports for all the reporting in this system, either way the reporting is fairly straightforward stuff, not really complex reports.  Because the reporting is simplistic, I want to use someone who is not a programmer to develop the reports, I have confidence that she can produce the reports as she has done som Crystal Reports in the past.  However, I cannot figure out how to develop the reports.  It appears that she will need ...Show All

I am basically copying the entire db - with the exception of a few tables. package.transactionOption = required , and all tasks transactionOptions are set to supported. Several questions.

• Windows Forms autocomplete AND dropdownlist combobox

  I want to give the user the functionality of the autocomplete, allowing them to enter one or more letters and receive a list of possible entries, whilst also ensuring that the user can only select an item from the list and not type any old thing. I know that I cannot use the dropdownlist list option along with autocomplete, but how can I make sure that the user does not enter invalid data Basically, at all times during the edit process, I want the data in the combo to be valid, so if a user enters invalid data, maybe the previously selected entry should be selected Whatever works best.

• SQL Server remote queries (linked servers) wait or timeout during a DBReindex of any table/index

  SQL2000 SP4 - build 2039 and also tested with a newly applied build 2162 It looks like when a SQLMaint optimization job OR a DBCC DBReindex is executed on ServerA, remote queries (at least using linked servers) to ServerA do not work.  They wait until the DBReindex is complete or until the connection (if connection has a specified timeout) times them out. Why can I not execute a remote query during an index rebuild   The query being run in the remote connection is very simple and does not read a table being 'reindexed'.  IE, I can run the same query locally during the reindex and it works.
