Cutting Edge: Build Providers for Windows Forms

  

In ASP. NET and Windows Forms projects, some file types are treated differently than others. For example, ASPX and ASCX files are dynamically parsed and compiled to an assembly on the fly. The contents of an XML Schema Definition (XSD) file are used to create a new, strongly typed DataSet-based object at design time.

Cutting Edge: A New Grid Control in Windows Forms

  

Grid controls are essential in many of today's apps. Until now, though, most developers using Visual Basic® have had to buy third-party components to get an effective, easy to use grid component. The Windows® Forms DataGrid turned out to lack too many features for the average developer.

Cutting Edge: Using Windows Hooks to Enhance MessageBox in .NET

  

It's fairly safe to assume that all programmers working in Windows® environments are familiar with MessageBox. The MessageBox function displays a message through a popup dialog box and lets programmers add dialog buttons and icons to the message to improve user feedback.

Cutting Edge: Windows Hooks in the .NET Framework

  

If you wanted to, you could distinguish two general categories of classes in the Microsoft® . NET Framework-classes that introduce new functionality such as XML readers and ADO. NET providers, and collections and classes that wrap underlying Win32® system functions.

.NET 4: Windows Workflow Foundation Production Environment footprint

  

Hi There,

We are currently an ISV evaluating WF4 for use as a Rules/Workflow engine, possibly intending to use the 'Forward-chaining' rules engine from WF3 in WF4. We currently have no WF assets.

We need to understand what the production environment footprint would be for WF4 and/or WF3.

I cannot find any useful info easily, so my questions are as follows,

1. What Server versions support WF4/3? W2003, W2008 etc

2. If I host my workflows in IIS what version of IIS will I need?

3. I have not got too far into WF yet, but I assume there are various datastores, what is the minimum version of SQL server I would need?

Thanks for you help


Why would I use Windows Workflow Foundation for Page Flow?

  

I just finished watching the WebCast that Israel Hilerio did on using WF within ASP.NET.  I keep seeing this example of using Windows Workflow Foundation for managing your page flows.  Is that something that just works well as an example?  Obviously we're always trying to preserve a Model View Controller pattern when building user interfaces and until now the User Interface Process application block suits us quite nicely.  This gives us the same capabilities through configuration that you're building into a workflow.  Wouldn't the in-process application block solution be less complicated?  What does WF give me above and beyond UIP that can help me sell this as a reason to start using WF.

By the way, I realize this isn't the only use of WF,  I will also start to look for opportunities to build inter-app business process workflows (and maybe someday even extra-app SOA aggregate solutions ... assuming I can figure out when I should use BizTalk for this and when I should use WF?????).

I guess there is a couple of quesitons in there :)  I look forward to anyone helping me sort all this out.  I DO want to find reasons to start using WF but I just don't know if page flow (from what I've seen so far) has a strong enough value prop.
