• Visual Studio 2008 (Pre-release) Entity Framework & Entity Attribute Value (EAV) Models

  What I've seen so far comming with the next release of ADO.NET and the Entity Framework is absolutely amazing; you efforts will be much appreciated! I do have one question though which relates to dynamic entity attributes that can be defined at runtime; more specifically something known (and often frowned upon) as Entity Attribute Value (EAV) Models. I realize there are contrary views on the validity of this model in a relational space and hope to avoid "good or bad" discussions in the thread ;-) Specifically, it has been demonstrated how we can perform logical/conceptual mapping and in turn generate logical objects that map to our entity objects. How will we map entity attributes that are unknown at mapping/compile time Will the ...Show All

• Visual Basic accessing information in an opend word document

  I am trying to create an application that will open a Microsoft Word document then be able to access what the user types in to it. I'm using visual studio 2005. I have opened the document in two different ways; using the shell method and creating a new variable as a process, but once the word document is open, I cannot figure out how to access it's information. If anyone knows how to make the ms word application save, copy/paste, or knows a way for my application to access its information let me know. I've created the application once using a RichTextBox built in to my application, but my client (I'm a college intern in over my head in software development) prefers to enter the data in MS Word.
