Release. Com.WordToAccessFigC.jpg' alt='Microsoft Activex Data Objects Library Missing Books' title='Microsoft Activex Data Objects Library Missing Books' />Object is correct in theory, but, unfortunately, very difficult to manage in practice.If one ever slips anywhere and uses two dots, or iterates cells via a for each loop, or any other similar kind of command, then youll have unreferenced COM objects and risk a hang.In this case, there would be no way to find the cause in the code you would have to review all your code by eye and hopefully find the cause, a task that could be nearly impossible for a large project.The good news is that you do not actually have to maintain a named variable reference to every COM object you use.Instead, call GC.Collect and then GC.Wait. For. Pending.Finalizers to release all the usually minor objects to which you do not hold a reference, and then explicitly release the objects to which you do hold a named variable reference.You should also release your named references in reverse order of importance range objects first, then worksheets, workbooks, and then finally your Excel Application object.For example, assuming that you had a Range object variable named xl.Rng, a Worksheet variable named xl.Sheet, a Workbook variable named xl.Book and an Excel Application variable named xl.App, then your cleanup code could look something like the following Cleanup.GC. Wait. For. Pending.Finalizers. Marshal.Final. Release. Com.Objectxl. Rng. Marshal.Final. Release. Com.Objectxl. Sheet. Book.CloseType. Missing, Type.Missing, Type. Missing.Marshal. Final. Release.Com. Objectxl. Book.Marshal. Final. Release.Com. Objectxl. App.In most code examples youll see for cleaning up COM objects from.NET, the GC. Collect and GC.Wait. For. Pending.Finalizers calls are made TWICE as in GC.Collect. GC. Wait.For. Pending. Finalizers.GC. Wait. For. Pending.Finalizers. This should not be required, however, unless you are using Visual Studio Tools for Office VSTO, which uses finalizers that cause an entire graph of objects to be promoted in the finalization queue.Such objects would not be released until the next garbage collection.However, if you are not using VSTO, you should be able to call GC.Collect and GC. Wait.For. Pending. Finalizers just once.I know that explicitly calling GC.Collect is a no no and certainly doing it twice sounds very painful, but there is no way around it, to be honest.Through normal operations you will generate hidden objects to which you hold no reference that you, therefore, cannot release through any other means other than calling GC.Collect. This is a complex topic, but this really is all there is to it.Once you establish this template for your cleanup procedure you can code normally, without the need for wrappers, etc.I have a tutorial on this here Automating Office Programs with VB.Net COM Interop. Its written for VB.NET, but dont be put off by that, the principles are exactly the same as when using C.Connecting Outlook to Databases.Connecting Outlook to Databases. Download Crack For Crime Life Gang Wars Trainer . A common question is, Can I connect Outlook with my existing customer databaseDefinitely yes, using the resources on this page.Two basic approaches are available Expose database information in Outlook either directly or by synchronization.Write your own code to make the database connection and create, modify, and delete records.ADO, a programming library included with Office to facilitate database connections, is most commonly used in this scenario.Replication APIFor Outlook 2.Microsoft provides a programming interface to synchronize an external data source with an Outlook.Outlooks ability to expose data from Share.Point lists is an example of this use of a proxy.To make this technique work, you need a wrapped.For more information, see LINQ Queries.If your main interest in treating Outlook as a database is to be able to run queries against its data, the capabilities of the new LINQ query feature for.NET 3. 5 Visual Studio 2.In the article Querying Outlook and One.Note with LINQ, Stefan Cruysberghs shows how to use LINQ to query Outlook messages, appointments, tasks, contacts, and notes with several very practical examples, including running a single query to get the count of messages sent for each day during the past week.ADOA flexible method for using Outlook with a database is Active.X Data Objects ADO, the programming interface for OLE DB database technology, which allows you to connect to virtually any kind of data source.ADO 2. 0 is included with Office 2.Outlook. Later versions of Office come with later versions of ADO.In. NET applications, youd use its equivalent ADO.NET. If you want to synchronize data between Outlook items and database records, you might link the Outlook item and the database record through a custom ID field on the Outlook item that has a counterpart in the database, both holding the same values.See Developer information about the calendar changes in Outlook 2.Service Pack 2 and later versions about changes related to the Entry.ID in appointments that may make it a poor choice for this kind of linking.My book, Microsoft Outlook Programming Jumpstart for Administrators, Developers, and Power Users, includes practical examples for connecting to Access and SQL Server databases with both DSN and DSN less connections, populating a combo box from a database table, and using a database to generate a sequential unique ID.You can download the sample code from the get Sues code link below.Also see DAODAO Data Access Objects, an older database connection technology that supports ODBC Open Database Connectivity drivers and works with Office 9.Many of Microsofts sample forms and code examples demonstrating OutlookAccess connectivity use DAO.Web Service Outlook 2.In Outlook 2. 00.Windows Share. Point Services site are copied a background process to a proxy.The underlying WSS feature that supports this functionality is a web service.Therefore, you can use a similar web service to expose any kind of data in Outlook.As long as it uses the same contract as the WSS web service, Outlook will handle the data just like the native WSS contact and event data.Examples are available for both contacts and calendar from Microsofts Stephen Toub, who pioneered this technique Linked Tables.Without programming, you can add a table linked to an Outlook or Exchange folder to any Access database, using drivers built into Office 2.In Access, click the New Table button to add a new table.In the New Table dialog, choose Link Table, then click OK.In the Link dialog, under Files of type, choose Outlook or Exchange.If youre prompted for an Outlook profile, indicate which one you want to use.In the Link ExchangeOutlook Wizard, choose the address book or folder you want to link to, then click Next.Give the linked table a name, then click Finish.See the MSKB article OL2.How to Use Your Outlook Items with Other Office Programs for more information.Unfortunately, this method has at least three huge limitations and, therefore, is not recommended The linked table ignores any custom fields.Not all address fields are linked.The Home and Office addresses each are listed as one field, while the Business address probably whatever is the default mailing address is parsed into its street, city, etc.Not all fields are included for all items not even all essential fields.You can see the fields available by switching to Design View.Michael Kaplan wrote articles in the August and September 2.Smart Access newsletter that explain how to get around the above limitations and make this method work much better.Unfortunately, we have not been able to duplicate his results.The August article is available on MSDN The Jet 4.ExchangeOutlook IISAM.Samples.
