• StefanKZVB opposite of XMLConvert class

  Hi! I was wondering if there is a class or method that does the opposite to what XMLConvert class does. i.e. convert a CLR type to a valid string for an XSD. Thanks in advance! Hi Derek, XMLConvert indeed is not what I'm looking for. That's why I'm asking for something that does the opposite. XMLConvert.ToString also does not do that. It returns culture sensitive string. I want to get an XSD valid string. Hi, I think the XMLConvert class does what your looking for. XMLConvert.ToString() method maybe. Hope thats what your looking for. Derek you are right! Here is the document that describes ToString() method (I home the link works): ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.VisualStudio.v80.en/WD_XML ...Show All

• BalajiSanro How should I send query to datatableadapter?

  I can only set a static query in DataSet designer How do i send and set query to DataTableAdapter by the code I don't think you can do this, one of the limitations when using the DataSet/TableAdapter wizard. You will have to create either other TableAdapters with a different query or programmatically as shown, use the standard approach (not using the wizard) of using the "raw" DataAdapter. Thank you. but i don't want to use DataAdapter . All i say is about DataTableAdapter Hi I want to use this in Win App. Double click in the dataset designer on your TableAdapter. Now use a partial class like the fo ...Show All

• veep Version 2.0 downloaded - now getting can't load messages on reboot

  Upon downloading the latest driver and ATI Control Center for my ATI X1300P video card, I was instructed to install .NET version 2.0, for it to work (hopefully for the video driver and not that pesky ATI Control Center application). I am working with Windows XP, Service Pack 2, and have no other reason to download this software - I don't even understand why I really need it. Anyway, I downloaded Microsoft .NET Framework Version 2.0 Redistributable Package (x86), and am now getting 2 messages on reboot: Could not load file or assembly 'MOM.Implementatiom, version 2.0 2589.34834 Culture=neutral, PublicKey Token=90ba9c70f846762e' or one of it's dependencies.

• moerderin CodeDom / Code Generator issue?

  I've discovered (a bug ) that has become a minor annoyance since our migration to the .NET 2.0 framework. We employ a code generator for the creation of many of our boiler plate classes (DAO / Domain Object type stuff)... which worked great under 1.1. When we upgraded to 2.0, I've noticed that the files it generates sometimes are not properly formatted. They still compile fine and, in fact will usually re-format if you open them in VS and then Ctrl-K, Ctrl-D, but the real issue is that if left in their original format, they really screw up our DIFF tool when compariing new minor revisions of files originally authored with the 1.1 generator. Here's what I mean: // The old way namespace ns1 { public class MyClass { private string m_st ...Show All

• sugrhigh listen port

  hi please help me. I have a question about ports & sockets . I am trying to write a program that cans listen to the port 80/8080 and deagnose pdf or zip files from other files(html,...). then recive this files from port . I know how resice the file by c#.net but I do not know how deagnose files type . thanks. If you're reading the file over the TCP (i presume) port then you will have to read the first few bytes to determine the file type. That is pretty simple: for instance, the every PDF file starts with the byte stream: %PDF-<version number> where <version number is something like 1.3 or 1.5. Zip files start with the byte stream: PK Hope this helps. ...Show All

• Dietz Xsd v2 and anonymous includes

  I've got an XML schema where I include a set of anonymous types. When running XSD to generate a class it doesn't seem to handle it very well.

• ksona configSource - share connection strings file across web-services ?

  We wish to have a single (external) config file that stores database connection strings, shared across a number of web-services that all connect to the same database. This would allow a connection string to be changed in a single file that then applies to all relevant web-services. Possibilities include the .NET configSource, or EntLib 2.0's "File Configuration Source" (I'm using Data Access block). But I believe that .NET 2.0 only allows configSource to be in a relative sub-directory, and can't access relative parent directories, so this wouldn't work for sharing a config file across web-services At least that's what this post suggests: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=146960&SiteID=1 Does .NET ...Show All
