Error Created when opening beta 1 file in beta 2

Go Edit > Find and Replace > Quickfind

Search for 'Namespace' in the current project and that will take you to the problem section of code.

Copy & Past this section of code below over the code that was generated by Beta1, but replace the ######### with the name fo your startup object (I have left .Form1 in to give you a better idea of what this line does because for most smalls apps it will be Form1).

Namespace My 'NOTE: This file is auto-generated, do not modify it directly. To make changes, ' or if you encounter build errors in this file, go to the Project Designer ' (go to project properties or double-click on the My Project node in the ' Solution Explorer), and make changes on the Application tab. ' Partial Class MyApplication <Global.System.Diagnostics.DebuggerStepThrough()> _ Public Sub New() MyBase.New(Microsoft.VisualBasic.ApplicationServices.AuthenticationMode.Windows) Me.IsSingleInstance = false Me.EnableVisualStyles = true Me.SaveMySettingsOnExit = true Me.ShutDownStyle = Microsoft.VisualBasic.ApplicationServices.ShutdownMode.AfterMainFormCloses End Sub <Global.System.Diagnostics.DebuggerStepThrough()> _ Protected Overrides Sub OnCreateMainForm() Me.MainForm = Global.#########.Form1 End Sub End Class End Namespace

Following this both my little apps that I wrote in Beta1 now work under Beta2.

Hi,

The error you are seeing is a result of namespace changes that were made between Beta 1 and Beta 2. Although you can simply globally replace System.Windows.Forms.[WindowsFormsApplicationBase/ShutdownMode/AuthenticationMode/etc] with Microsoft.VisualBasic.ApplicationServices to mitigate these errors, you may want to have Visual Studio regenerate the files for you.

Here's how you can do that:
- Select "Show All Files" in the Solution Explorer
- Rename "MyApplication.myapp" to "Application.myapp"
- Remove "MyApplication.vb" (This is the file that's likely giving you errors)
- Right-click "Application.myapp" and select "Run Custom Tool"
- Rename "MyResources.resx" to "Resources.resx"
- Remove "MyResources.vb"
- Right-click "Resources.resx" and select "Run Custom Tool"
- Rename "MySettings.settings" to "Settings.settings"
- Remove "MySettings.vb"
- Right click "Settings.settings" and select "Run Custom Tool"
- Rename "MyEvents.vb" to "ApplicationEvents.vb"

These steps will effectively upgrade your project to match the structure that's used in Beta 2 (and RTM). It's a somewhat annoying process, but (for what it's worth...) you only have to do it once per project.

Additionally, you may run into compilation errors in your code because other types in My have changed namespaces. Here's a quick list:

The following types in System.IO have been moved to Microsoft.VisualBasic.FileIO
-TextFieldParser
-FileSystem
-SpecialDirectories
-MalformedLineException
-UIOption
-UICancelOption
-SearchOption
-RecycleOption
-FieldType
-DeleteDirectoryOption

The following types in System.Diagnostics have been moved to Microsoft.VisualBasic.Logging:
- FileLogTraceListener
- Log
- LogFileCreationSchedule
- LogFileLocation
- DiskSpaceExhaustedOption

The following types in System.Windows.Forms have been moved to Microsoft.VisualBasic.ApplicationServices:
- ApplicationBase
- AssemblyInfo
- AuthenticationMode
- BuiltInRole
- BuiltInRoleConverter
- ConsoleApplicationBase
- ShutdownMode
- WindowsFormsApplicationBase

You may also receive compilation errors for the following types, which now live in the Microsoft.VisualBasic.Devices namespace:
- Audio
- Clock
- Computer
- ComputerInfo
- Keyboard
- Mouse
- Network
- NetworkAvailabilityEventArgs
- Ports
- ServerComputer

We really appreciate your early adoption of VB Whidbey, and realize that these sorts of change are a big pain in the pain place... Sorry 'bout that. The changes were made in response to customer feedback that the previous organization was confusing, and we wanted to get things right for the final release of Whidbey.

Don't hesitate to let me know if you run into any similar issues.

Thanks!
