When you use the various indexers of the DataSet and DataTable type, you can interact with the contained data in a straightforward but loosely typed manner. Recall that this approach requires you to treat the data as a tabular block of cells, as in this example: static void PrintDataWithIndxers(DataTable dt) { // Print the DataTable. for (int curRow = 0; curRow < dt.Rows.Count; curRow++) { for (int curCol = 0; curCol < dt.Columns.Count; curCol++) { Console.Write(dt.Rows[curRow][curCol].ToString() + "\t"); } Console.WriteLine(); } } The CreateDataReader() method of the DataTable type offers a second approach, where you can treat the data in the DataSet as a linear set of rows to be processed in a sequential manner. This allows you to apply a connected data reader programming model to a disconnected DataSet: static void PrintDataWithDataTableReader(DataTable dt) { // Get the DataTableReader type. DataTableReader dtReader = dt.CreateDataReader(); while (dtReader.Read()) { for (int i = 0; i < dtReader.FieldCount; i++) { Console.Write("{0}\t", dtReader.GetValue(i)); } Console.WriteLine(); } dtReader.Close(); } Finally, you can use a strongly typed DataSet to yield a code base that allows you to interact with data in the object using properties that map to the column names in the relational database. Using strongly typed objects allows you to author code such as the following: static void AddRowWithTypedDataSet() { InventoryTableAdapter invDA = new InventoryTableAdapter(); AutoLotDataSet.InventoryDataTable inv = invDA.GetData(); inv.AddInventoryRow(999, "Ford", "Yellow", "Sal"); invDA.Update(inv); } pdf password recovery online free: Protect PDF - Protect your PDF documents online - PDF2Go how to protect pdf file from copying online Unlock your password protected PDF files online for FREE !

Note You only use the LINQ to DataSet to apply LINQ queries to DataSet objects returned by a data adapter, but this has nothing to do with applying LINQ queries directly to the database engine itself. 23 will introduce you to LINQ to Entities and the ADO.NET Entity Framework, which provide a way to represent SQL queries as LINQ queries. pdf merge online: Merge PDF - Combine /Join PDF Files Online for Free - Soda PDF pdf password remover online Unlock your password protected PDF files online for FREE!

Recover lost password . This document's ... Out of the box, the ADO.NET DataSet (and related types such as DataTable and DataView) do not have the necessary infrastructure to be a direct target for a LINQ query. For example, the following method (which uses types in the AutoLotDisconnectedLayer namespace) results in a compile-time error: static void LinqOverDataTable() { // Get a DataTable of data. InventoryDALDisLayer dal = new InventoryDALDisLayer( @"Data Source=(local)\SQLEXPRESS;" + "Initial Catalog=AutoLot;Integrated Security=True"); DataTable data = dal.GetAllInventory(); // Apply a LINQ query to the DataSet var moreData = from c in data where (int)c["CarID"] > 5 select c; } If you were to compile the LinqOverDataTable() method, the compiler would inform you that the DataTable type provides a query pattern implementation. Similar to the process of applying LINQ queries to objects that do not implement IEnumerable<T>, ADO.NET objects must be transformed into a compatible type. To understand how to do so requires examining the types of System.Data.DataSetExtensions.dll. pdf password remover online Unlock PDF – Free Online PDF Password Remover - Smallpdf.com

Problems You want to use subscripts and superscripts Since each browser uses different vertical offsets and font sizes for subscripts and superscripts, you may also want to standardize their styles to fit your tastes For example, Firefox 2 lowers subscripts just a little, and Opera 9 uses a larger font size for subscripts and superscripts The first three screenshots in the example show how subscripts and superscripts look in Firefox 2, Internet Explorer 7, and Opera 9 The fourth screenshot shows subscripts and superscripts styled to look the same in all browsers Solutions You can mark up inline content with <sub> for subscripts and <sup> for superscripts Subscripts and superscripts are semantic elements In foreign languages, such as French, certain characters must be superscripts to be correct, such as the lle in the abbreviation for mademoiselle In math, subscripts and superscripts change the meaning of a number. The System.Data.DataSetExtensions.dll assembly, which is referenced by default in all Visual Studio 2010 projects, augments the System.Data namespace with a handful of new types (see Figure 22-27). Figure 22-27. The System.Data.DataSetExtensions.dll assembly The two most useful types by far are DataTableExtensions and DataRowExtensions. These classes extend the functionality of DataTable and DataRow by using a set of extension methods (see 12). The other key class is TypedTableBaseExtensions, which defines extension methods that you can apply to strongly typed DataSet objects to make the internal DataTable objects LINQ aware. All of the remaining members within the System.Data.DataSetExtensions.dll assembly are pure infrastructure, and they are not intended to be used directly in your code base. Writing logging event data to a remote server is easy SocketAppender will do the job for us. We just need to pass to it the host name, the port, etc., as a part of the configurable bean properties.
