For a search by product, the code builds criteria using a subquery that finds the ContactID from records in the tblContactProducts table that match the product you selected Finally, if you leave the Include Inactive Contacts check box unchecked, the code adds a test to include only records that are active After examining all the possible filter values the user could have entered, the code checks to see if there s anything in the filter string (varWhere) There s no point in opening the form without a filter, so the code displays a message and exits, leaving the form open to allow the user to try again The final part of the procedure builds a simple recordset on the tblContacts table used in both the frmContacts and frmContactSummary forms, applying the WHERE clause built by the code in the first part of the procedure. barcode reader vb.net source code Read Barcodes from Images C# /VB.

In chapter 6, we presented a high-level view of some of the capabilities of LINQ to SQL. By now, you should have enough tools under your belt to start working with LINQ to SQL. In this chapter, we dive a bit deeper and explore how the technology works under the covers. We ll start by looking at the mapping options at our disposal. We explain not only the mapping options, but also how to employ some of the tools that come with Visual Studio 2008 to make mapping easier. We ll continue by looking at the underlying technologies that make LINQ to SQL behave differently from LINQ to Objects. We won t have enough time to create our own O/R mapper, but we ll discuss how they differ at their core. We ll conclude this chapter by examining the object life cycle and see how LINQ to SQL manages the objects through their changes until they are updated. By combining the mapping, translations, and object life cycle, LINQ to SQL emerges as a powerful extension of the LINQ family of technologies. 23 23 barcode reader code in asp.net c# asp.net read barcode-scanner - Barcode SDK

Microsoft Office Access 2003 Inside Out When you first open a Recordset object in code, its RecordCount property is 0 if the recordset is empty and is some value greater than 0 if the recordset contains some records. The RecordCount property of a Recordset object contains only a count of the number of rows visited and not the number of rows in the recordset. So if it finds some rows, the procedure moves to the last row in the temporary recordset to get an accurate count. When the record count is greater than 5 and the frmContacts form is not already open, the procedure uses the MsgBox function to give the user the option to view a summary of the records found in the frmContactSummary form or to display the records found directly in the frmContacts form. (As noted earlier, both forms use the same record source, so the code can apply the filter it built as it opens either form.) We ll examine how the frmContactSummary form works in the next section. 23 23 22 23 23 23 In the previous chapter, we extended the Book and Subject objects of our running example using several custom attributes. By decorating the classes and properties, we demonstrated how to eliminate repetitive traditional ADO.NET code and let the framework handle mapping the relational tables to our business entity classes. We re able to specify the mappings once. The framework can determine the SQL necessary to translate our declarative query constructs into a syntax that our database can recognize. By changing the business needs, we do not need to implement an entirely different data tier, potentially with separate code both in our application and on the database itself. We can let the framework manage the language translations based on the mappings we set up. When we initially presented the mappings, we showed how to manually map the values. The attribute-based mappings provide a direct method of specifying the mappings. In addition to explicitly specifying the mappings with attributes, Visual Studio 2008 offers three other mechanisms to assist with mapping data to your objects. The full list of mapping options consists of As you saw in the cmdSearch_Click procedure in the previous section, the user gets to make a choice if more than five rows meet the entered criteria. To examine this feature in more detail, make sure the frmContacts form is not open, and ask for a search of contacts with a Contact Type of Customer in the fdlgContactSearch form. The result should look like that shown in Figure 23-17, in which 13 contacts are categorized as customers. Figure 23-17. The message box that appears when the cmdSearch_Click procedure returns more than five rows. barcode reading in c#.net Reading barcode using vb.net code - CodeProject
