• Fusion1224 System.Threading.Thread & ThreadPool

  Hi, All! If it’s possible please answer me on one question: ThreadPool is created on application start but it doesn’t work until I call ThreadPool.QueueUserWorkItem () method. But if I don’t use ThreadPool and use System.Threading.Thread myThread = new Thread(new ThreadStart(OnStart)); myThread.Start(); then whether will be myThread belong to default ThreadPool Or it will be independent from everyone Or all of threads must belong to created ThreadPool always In http://blogs.msdn.com/yunjin/archive/2005/07/05/435726.aspx Yun point that all of assesible for user-code thread belong to ThreadPool Please let me know your meaning about this problem.

• cverdon DataReader Loop and Dataset Question

  I am looking for the best way to do this very common need of getting data from one table to another. Both tables are in sql server 2000, different databases. I am opening a SQLDataReader (for performance), then need to load them into a Dataset. From the Dataset there are SQLCommandBuilder and SqlDataAdapters available to give correct INSERT/UPDATE syntax for the destination table (on a seperate instance of SQL Server 2000) I got the data in the reader, opened the needed objects to pull the data over. I dont want to loop through every row of the DataReader because the schemas are the same (between source and destination table). How can I load the DataReader into the DataSet that is connected with the SQLDataAdapter without ...Show All

• Hans1982 WinFX and Interop

  Hello everyone! Right i was wondering since WinFX (.Net 3) is part of the Subsystem in Windows Vista if its possible to use the Managed API framework to communicate with other running applications using User32.dll in .net 2.0 i have to use Interop to import the dll and manually managed the code. But since WinFX is a subsystem surely there is already a managed API for User32 or something I cant find anything about the new WinFX features or documentation on the new procedures, namespaces and classes. Does anyone have any links or ideas to some form of documentation or anything of interest Thanks Thanks for the article link. Why do Microsoft continue to make silly mistakes Since .net 3 isnt actually any ...Show All

• dba_sql Attributes and inheritance on fields/properties/methods

  Hi there! I'm trying to work out how (if at all) attributes are inherited on overriden fields properties and methods. According to this msdn page , they are inherited, but how do you retrieve these attributes Here's some code I'm testing with... I've discovered that the static method Attribute.GetCustomAttribute works as you would expect with inherited attributes, just in case anyone else is having the same problem. It would still be helpful to understand why the above doesn't work like this though. TaylorMichaelL, I could freakin kiss you. I've been grappling with this exact problem for almost a week, and your post solved it right away. Thank you! 大家好，我 投入 网 技 ， 大家在以后的日子里多多指教哈哈 1)注 的 示名 ...Show All

• DavidAragornHouse compact access 2007 database

  Does anyone knows how to compact an access 2007 database with .net The previous code with JRO.JetEngine is not working for 2007 format. We used that code for previouse db but not working for the latest one. I haven't tried using JRO to do this myself, but does your connection string specify the new database engine for Access 2007 (not Jet OLEDB) I believe that you have to use the Access 2007 Application object: How to: Compact and Repair a Database I also have an application that needs to CompactDatabase and run on any machine regardless of their Office version (if any).

• .Net General [Best Practice] Verify a value is part of an enumeration

  What would be the best way for verifying, upon converting an int to an enumerated type, that the value actually exists in the enumeration Ideally, this would work with [Flags] and non-[Flags] enumerated types. A case statement would work, but is clearly undesirable, unless one does some sort of code generation. Perhaps checking int.TryParse((EnumeratedType){int value}, out dummy).ToString()) would work, but that seems awfully kludgy. I'm not particularly thrilled with using reflection to test enum values, so I think I'm back to either manually coding verification routines or using some sort of code generation. What would be really nice is an option to have the compiler turn Enum.IsDefined into the most ...Show All

• ZaaM IT Ultra-fast deserialization/serialization

  Hi, I'm wondering if there is a way to speed this up: I have objects that implement the following methods: public void Serialize(System.IO.BinaryWriter writer) { writer.Write(this.price); writer.Write(this.size); writer.Write(this.dateTime.Ticks); } public MyObject Deserialize(System.IO.BinaryReader reader) { return new MyObject(reader.ReadDouble(), reader.ReadInt32(), new DateTime(reader.ReadInt64())); } That's what I use for serialization & deserialization. Currently I manage to write 10,000,000 objects in 5.5 seconds, however my Raid 0 drives can write up to 140MB/s, so I think there should be some upside left (10mio objects result in 195MB file).

• V.E VB.Net Datatables and Identity Fields problem...

  ok im adding a new row into a datatable , the table on the database has an identity field. When the row is added the database updates correctly and i get a new value in the identity field as expected. What doesnt seem to be happening is the new identity value isnt being reflected in the datatable. When i query the table later on in the application theres only a DBNull value where the new ID should be. Heres the code im using to update the datatable, how would i make the new identity field appear in it Theres no obvious datatable.refresh method and its a pretty large table anyway, id imagine it would be a bit wastefull to have to reload it all every time i add a new record to it. is there a way to get the new identity value set in th ...Show All

• J-Chen How to handle data in different tables?

  I was wondering if someone could point me to a tutorial that might help me I have an application that I'm developing that will display a tabbed form which needs to contain data from different tables. For example, my database has a contact table with typicall information and then it also has a lead table which contains information if the contact is a sales lead. They are linked together by a common contactID column. There are a few other normalized tables also like an AlternateAddress table. My first problem was that I could only get the binding source to connect to a particular table. This was a problem cause the data that I need to modify is normalized across a few different tables. My solution to that problem was to create a view ...Show All
