I have both the VB and C# versions of Visual Studio 2008 Express. When I run a console application in either version, instead of the console opening in an old DOS style command window like it does in VS 2005, it actually blacks out both monitors attached to my computer and treats the entire screen real estate as the console.Anyone know how to get the app to run in a small command-type window when I run it? It's like the console is running Full Screen. If I set a break point, switch from the IDE t the console and then hit Alt+Enter it switches to the small window that I want, but I still can't figure out how to make the app start with the console that way.I could post a screenshot but it would look like a big black square...no window, no frame, just the inky blackness of frustration.

I have another question about my customizable Menu/Tool/StatusStrip control.
I have three controls called CustomizableMenuStrip, CustomizableToolStrip and CustomizableStatusStrip. Each of those controls has a property called Appearance, which accepts an instance of a component called AppearanceControl.
The AppearanceControl component basically exposes all color properties for the customizable strips, so the user can edit them, and more importantly exposes a ToolStripProfessionalRenderer which the three strips have to use. This way the three strips are rendered with the colors the user chooses in the AppearanceControl.
Now, I'm wondering if I'm doing things the right way. When any of the color properties in the AppearanceControl has changed, all the strips that use that particular AppearanceControl should have their Renderer set again, and should be invalidated.
I figured the easiest way (and probably the only way?) to go about this was to have the AppearanceControl raise an event (AppearanceChanged), which the three strip controls listen for. When that event is raised, the strip controls can set their Renderer to the Renderer that the AppearanceControl exposes, and then invalidate themselves.

I'm developing a device app in VB.net that will access a SQL Server database. I need to establish a connection when the app is launched, and keep the connection open until the app is closed. I've done the following:In the Master Module:
Public CNN
As SqlConnection
In the Main menu form load:
CNN =
New SqlConnection(sqlConnString)
CNN.Open()
Then when I want to read from the database:
Dim sqlDR
As SqlDataReader
SQL = "SELECT Name FROM Table"
[code]....
When I run the same code without the global CNN, but rather dim the connection inside the Select function, all works well.
