• Visual Studio Copy WSSF and use as base for new GA package (formerly Where are the configuration files located?)

  I want to create a custom package. I have used the "Giuidance Package Development" project to start me off but I want to look at some example packages to see how they work. Specifically I want to see how code is generated from a database schema and how code is generated from classes. I think the database part can come from the WSSF. I'm not sure how the BusinessEntity classes work but I think they can be found in the same package. Should I be looking at the Guidance Automation configuration file for WSSF If so where can I find it I want to create a guidance package creates a data access layer, business entity layer, a web service layer (all of this can be done with the WSSF I know) but also I want my classes to act as data providers of ...Show All

• SQL Server Which database to use?

  Hi there, I'm about to start work on a single-user app. I'll be writing it in C#, as a Windows Application, and am trying to decide what database to use. All installation (application and database) must occur through an installation package - I will not have administration access to the customer machines. My customers will not have any database engines installed, but will use Windows XP SP2. I guess this means that if I use Microsoft Access I don't need to do any extra installation work - I can just install a blank DB MDB file in the application directory and go from there. However, I'd really rather use SQL Server Express if possible - what is involved in using SQL Express instead of Access Is it possible to automate installation of the S ...Show All

• Visual Basic How do i create event every time a property is changed

  How do i create event every time a property is changed. Something like a TextChanged. i have a property IPClass and want to update some other control in another form like a label depending in which instance if the control is it. I know i maybe able to use My.Forms.controlName... but i chose not to since i have multiple instances of it in a form. Hi, i found that i can accomplish my goal by just using Public Event ClassChanged() Public Event PrivatePublicStatusChanged() and in the places where u want to raise the event, eg. ' ip is a object of my custom class IPv4 ' The ClassChanged is a boolean variable that ' becomes true every time the _IPClass ' property is changed Set() is trigg ...Show All

• .NET Development Deleting a single row from related tables

  Hi, I have 3 related tables. First one is the parent and the other two are children of the first one. Ican navigate through parent and its children using DataGridViews and relations. When I delete a single row from my parent table I want to delete only its children not all the deleted rows in child tables.
