• .NET Development WebException: The underlying connection was closed

  Hi After upgrading our win client app to run on version 2.0 of the .net framework (prev. v1.1) on of our customers reports the following error when calling a web service on our server: System.Net.WebException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. The customer is using a proxy-server, but it worked fine before the upgrade, and other customers who are behind proxy-servers has no problems. The error does not occur when the customer accesses the web service using Internet Explorer. The customer is behind a firewall. /Daniel This is not an answer, but similar problem.

• Game Technologies: DirectX, XNA, XACT, etc. Game Loop? WTF?

  Maybe you mean XNA GSE 1.0 Beta2, which we played with in November Microsoft removed Beta2 from their download servers, because it was just wasting space. Also, it would be confusing to still have it pop up when you search for XNA. As far as I can tell, there is no difference between Beta2 and the final version. If you use the final version, and have problems compiling something which was written with Beta2, then I'm sure someone at Microsoft would like to know. ...Show All

• SQL Server UDF?

  I have a table of zip code ranges that map to regions: zipfrom zipto region I also have a list of companies and their zip codes: company zipcode What I would like to do is find the related region in the first table based on the company zip code. Do I need a function to do this or can it be done using T-SQL An example would be helpful. Thanks. You can use a join: select company, region from company join region on company.zipcode between region.zipfrom and zipto It will be helpful if the regions don't overlap, or you would get duplicates returned. I would also consider producing another table, a zip code table that has one zip code and relates to a region table, the ...Show All

• Visual C# NetworkStream doesn't support seeking

  I want to play sound from network stream. For playing sound i use directsound, but when i try to create SecondaryBuffer: try { ApplicationBuffer = new SecondaryBuffer ( this .netStream, ApplicationDevice); } catch ( Exception ex) { MessageBox .Show( ex.ToString()); } i'm getting error that netStream doesn't support seek operation.

• Windows Forms Searching for specific text data in the datagridview control

  I have been tearing my hair out looking for a way to search all the rows in a selected column of a databound datagridview control for specific text (like a combo box lookup) without success. I am beginning to think that it is not supported and I will have to buy something like vsflexgrid.net. Is there a way to do this without buying a third party control Thanks that looks like it will work. I am a little worried about speed and was hoping then the datagridview control would have an autosearch feature that I just didn't know how to turn on. I couls have as many as 150000 item in a lookup box using a datagridview.... ...Show All
