Therefore, this chapter will focus on the aspects of ADO. NET against a sample database. Should the user wish to edit values, a modal child form is displayed with several combo boxes containing the possible values for acceptable input to edit the row. Calling the EndEdit procedure of trowNewRow 2. From there, you'll begin a section illustrating how to perform basic database operations creating, reading, updating, and deleting of records. I'll then illustrate several techniques for reading and writing data in batch in order to keep round trips to the data server to a minimum and dramatically speed up insert operations. Finally, the chapter ends with a section on generating strongly typed datasets, using them in an MFC application, and the pros and cons of using untyped vs. NET data access layer. At this point, you'll be fairly comfortable with the basics of reading and writing data to a disconnected data table. I've verified the AcceptChanges procedure of trowNewRow is not explicitly being called by any of my code. Included in that section are tips on handling the common issues of dealing with disconnected data and auto-increment primary keys, and how to specify primary key information for untyped datasets. The strong-typing is preserved. Once finished with its work, the application could then connect the IMDB back to its data store and synchronize any changes that were made. Manually performing a WriteValue on the combo boxes 3. NET and disconnected data as well as the basics of constructing those objects and connecting to a data source. Manually checking the values of the row indicates the changes have indeed been recorded. After the user submits the changes by clicking an OK button, a procedure is triggered to evaluate whether or not a change was actually performed. Unfortunately, just as Release Candidate 2 for the Windows operating system was being released, Microsoft announced that for various reasons IMDB just wasn't ready for prime time and would not ultimately be a part of the Windows final release. I pass the reference by performing a "Select" procedure on the dataset and filtering by a unique ID field corresponding to the row that is to be edited. Every combination of the above Thank you in advance for any ideas or solutions. One of the key benefits of an IMDB is its support of the ability to search, sort, and filter data once it's been retrieved. The result is a single-item array of strongly-typed rows of the same schema as the dataset's from which I pass the first and only item as my object. I have tried the following: The user is allowed to input values and save them, each time creating a new record in the dataset. Binding to the source's display and value members works fine.

Each combo box is bound in the constructor for the child form in the fashion below: Binding to the source's display and value members works fine. The result is a single-item array of strongly-typed rows of the same schema as the dataset's from which I pass the first and only item as my object. The chapter begins with a section illustrating the basic terminology and classes specific to ADO. I have a VS smart device project containing a strongly-typed dataset. Therefore, the next section illustrates how to accomplish these tasks as well as how to create multiple filtered views on a single dataset. Calling the EndEdit procedure of trowNewRow 2. Included in that section are tips on handling the common issues of dealing with disconnected data and auto-increment primary keys, and how to specify primary key information for untyped datasets. Unfortunately, just as Release Candidate 2 for the Windows operating system was being released, Microsoft announced that for various reasons IMDB just wasn't ready for prime time and would not ultimately be a part of the Windows final release. The RowState, however, remains "Added" regardless of the changes.
