• Visual C# Public field not accessible, forced to create an accessor...why?

  I have run into this multiple times in the life of the app I'm working on. The scenario is simple. I've got a public field in a class that I create an instance of. I cannot access the variable via an instance, but I can if I access it via the base type or if I make it private and create an accessor. Initially, before adding the accessor, both the field and class are public and not static. The only pattern I can follow is that it is consistent across classes. Either all the public fields are open in a class or none. Any ideas on things to look at I can post some code if it comes down to it. Thanks!

• SQL Server Runtime temporary table in SQL2000

  I am trying to create a runtime temporary table at SQL2000 server in my VB 6.0 program. However, I am keeping getting "object not found" error from my program when I trying to issue a SELECT or INSERT statement in my program. Can anyone shows me how to do it properly. I thought I can create a temporary table with a # prefix as a table name. Am I correct Help is very much appreciated. John Tsoi If you are using connection pooling in your application you will grab "a" connection, does not need to be actually the one where you created the temp table before. DIsbaling connection pooling will help you in this case, but might not be the best solution. What about using a stored pr ...Show All

• .NET Development Add new record

  I learned how to edit a record, but now how do you add a new record Dim workRow As DataRow = workTable.NewRow() what is a datatable this is my hang up for now Davids Learning OK, I'll answer one question with a code example and then add some additional comments. A datatable is a type used in .NET to allow tabular data to be stored. If you familar with a database, then a datatable is a type that can be used to represent a table from a relational database. As its not a table in a database but a datatype that can be used to represent this data - it can also be created and used independently of any database to allow collections of tabular data to be used in you application.

• Software Development for Windows Vista Config Properties as Dependancy Properties?

  What is the best way to get .config values into my activities My initial thoughts are to create DependencyProperties which I set via AppSettings in the Workflow, and just bind them to my Activity properties. Is there any way to bind directly to them I guess this will also apply to Web Services, how the WSDL url is dynamically changed during deployments etc. Thanks, Dave Wow, I am suprised that we can't just bind to publicly exposed config properties, but I guess I can just add DependencyProperties in the Workflow code and manually hook these into my attributes - I was thinking of things like my Custom Email activity, which needs things like SMTP Host, User Name/Pwd etc.. Thanks for the help, Dave ...Show All

• Visual Studio 2008 (Pre-release) Eliminating a control if it binds to null

  I have a series of controls in a Gridview cell that are in a StackPanel binding to various fields on the same object. If one of the controls binds to a field that is null, I would like that control to not get created and all the controls under it to shift up. I've tried two ways, but I'm not very excited about either one. 1. Created a CellTemplate with a DataTrigger that checked the data and set the Visibility to collapsed. This has the right look, but my data is pretty sparse and I would like to only create the controls I really need. 2. Create serveral CellTemplate's. One for each purmutation of controls, and use a template selector. This works great for 2 or 3 controls, but gets out of hand rather quickly as I have to create 2^n t ...Show All

• SQL Server AVG Measure

  In AS2005 how i make a measure with tha aggregate function avg Thanks Javier, To create a new calculated member, go to the calculations tab in your cube in BI Studio and then do one of two things, click on the "New Calculated Member" button on the tool bar. It looks like a calculator - or you can go to the menu and select "Cube", "New Calculated Member". Once you have done that, you should put the name at the top in the box labeled "Name". (Average). Then in the "Expression" box, put the calculation. What you have looks correct, although it would probably throw an error if you divide by 0. I would suggest getting your cube created w/o the calculated member and then pul ...Show All
