• .NET Development Inserting a New Record with FormView in ASP.NET 2.0

  In the insert mode of form view, the primary key is hidden from the user. In the underlying access database, the primary key is autonumber. Clicking the autogenerated insert button causes the error: "You tried to assign the Null value to a variable that is not a Variant data type." Do you have to programmatically set the unique ID key, and if so how would you do that in Visual Web Developer The form view is linked to an access datasource with ...Show All

• SQL Server SQL2005 Database Schema without Assocated Owner?

  I was quite happy to see that schema names and database users had finally been separated in SQL 2005 and used it to finally clean up a mish-mash database that hosts a number of tiny unrelated applications. I created a new schema for each little section, and the schemas are all owned by dbo. There is no associated user with the schema. Really it all works great... ...except... from an ADP project in Access! If an object is in the dbo schema, or i ...Show All

• Software Development for Windows Vista Getting Vista File Open dialog with .NET application

  Our application is written in C# 2.0 and using standard file open/save dialogs. In XP, these are pretty basic dialogs, but on Vista they remain the xp-style dialogs and not the Vista-specific open dialog. I've noticed with MFC based applications, if you use the common dialog you can get the Vista specific open dialog when running the same app on Vista. Any idea how we can get the OS-specific open dialog in C# ... if not possible withou ...Show All

• Visual C# Changing width of scrollbar on combo box

  I'm currently writing a C# application that will utilize a touchscreen as the primary interface method. Since I'm using a touchscreen and not a mouse, large, easy to hit controls are key. This hasn't been a problem for the most part, but I'm running into trouble in a situation where I use a combo box. I can change font size of the items listed in the combo box, so each row is tall enough to hit easily. The problem is that there are more item ...Show All
