• Windows Forms How to debug data adapter fill errors

  Hi. I've got a C# application that uses an ODBC connection to retrieve data from a DB2 database. When running the application I get the following error: [OdbcException: ERROR [HY000] [IBM][Client Access Express ODBC Driver (32-bit)][DB2/400 SQL]SQL0802 - Data conversion or data mapping error.] Now it just so happens that this application is designed to retreive the data through a mail merge in word. It's using the Microsoft.Office.Interop.Word assembly to create a Word.Application object, then passing the necessary ODBC connection string and sql statement to the word document's MailMerge.OpenDataSource() function.

  Is there a bug with caching objects that are not DataSets in Office 2k3 docs Although the examples state that anything xml-serializable can be cached using the "Cached()" attribute, I have had no luck trying to cache a simple string in a Word doc. My code in ThisDocument.cs is something like: public partial class ThisDocument {     string id = string .Empty;     [Microsoft.VisualStudio.Tools.Applications.Runtime.Cached()]     public string ID     {         get { return id; }         set { id = value; }    ...Show All

• SQL Server Web synchronization for SQL Sever 2000?

  Knowing that web synchronization is a new feature comes with SQL Server 2005.  Is it possible to achieve http synchronization using SQL Server 2000 instead of SQL Server 2005 Is there other means of achieving http synchronization beside using SQL Server components like connectivity components and SQL Server Replication Listener The idea of the HTTP replicationg is to obviate the use of VPN tunneling.  You can still use tunneling to protect the data in 2000. Best way would be to have firewall to firewall VPNs with your SQL servers in DMZs on each site. ...Show All

• Software Development for Windows Vista Page

  How can I set the page size and other PageSetup parameters when creating and printing an XpsDocument PrintTicket pt = printQueue.UserPrintTicket; pt.PageMediaSize.PageMediaSizeName = PageMediaSizeName .ISOA5; seemed like the obvious thing but it is readonly. Thanks Michael Daniel, (our posts maybe just crossed) I'm using the overloaded constructor but isn't ISOA5 a known size I'd like to understand the reasoning as to why Width and Height are not set to a default for the passed PageMediaSizeName. It means every WPF program must store these defaults when it could very easi ...Show All

• Windows Live Developer Forums Edit Issues

  I'm having some issues with my editPost implementation. The first is that each time I edit a post the dateCreated moves back 5 hours. I am at GMT -5 which leads me to believe that the adjustment is being applied somewhere but I'm not doing it myself so I'm not certain as to where it is happening. I'm assigning the dateCreated value of the post I get from getPost to the dateCreated value of the post I'm assigning via the editPost. Along the way both DateTime.Parse and DateTime.ToString are used at least twice which leads me to believe they aren't changing it or the difference would be 10 or more hours not 5. Flow goes like this: 1) xml ...Show All
