• Windows Forms How to display SmartTags/DesignerVerbs in a home made DesignerHost

  Hello, I have a some custom controls that i drag and drop onto a form designerhost that i've implemented. The custom control i'm adding has its own designer that adds properties and designer verbs. My form designerhost is able to display the new properties generated in its designer, but the designerverbs are not visible. Which services/interfaces have to be implemented by my designerhost to get this to work (when I add my custom control to the Visual Studio form designer, the designer verb displays as expected). The designerhost currently implements the following interfaces IContainer, IComponentChangeService, IDesignerHost, IExten ...Show All

• Visual C# Database - Best Practices

  I am working on a database application and was hoping someone might be willing to give me some advice on what the "best practices" are regarding where to put my database access code: Should I place the database access code in my Main method, the Load Event of the main form, a seperate method inside my main form, or in a seperate class file Thanks! Here is a good list with resources, it is allways good to seperate it in tiers, but remember that it depends on your needs.

• Visual Studio 2008 (Pre-release) Custom TriggerActions

  Are we supposed to be able to create our own TriggerActions TriggerAction is not sealed, but the abstract 'Invoke'  method is defined as Internal in the base class, so there is no way it can be overridden outside of the WPF assembly. I should mention that I would like to create two trigger actions. The first will simply invoke a method (by name) on a target instance using reflection. The second will call Execute on an ICommand instance. The instances will be hooked up using {StaticResource}. I looked for something prebuilt to do this but I can't find anything. It seems like a common task to want to e ...Show All

• Visual Studio 2008 (Pre-release) WPF & Games

  Hello everyone, After learning of the number of possibilites of Windows Presentation Foundation I was, naturally, excited. But now I'm confused. WPF is based on DirectX. So when I develop games, do I use my DirectX wrappers and classes, or do I use WPF Thanks for your answer in advance. - Ryan.  We can say that WPF is a simplified layer over DirectX. It doesn't have all the resources of it. About game creation using WPF there are this site having tutorials including source code, executables etc: http://www.dmu.com     ...Show All

• Windows Forms MsgBox Font

  Seems like a simple solution, but can't find the answer.  How do you change the font properties for a Message Box. I want the text to show as Font Size 15 Thanks MsgBox("HELLO WORLD", MsgBoxStyle.OKOnly, "Title") You cannot modify the font properties or layout of the MsgBox since under the covers, it calls MessageBox in User32.dll. This Win32 C-function only exposes the owning window, text, caption, buttons to display, and dialog result. If you want to modify font properties, you'll have to create your own Form, as DMan1 mentioned. ...Show All
