The
Microsoft.VisualBasic namespace contains types that support the Visual Basic Runtime in Visual Basic.
For more information about the language elements in the Visual Basic Runtime, see Visual Basic Reference.
| | Class | Description |

 | Collection | A Visual Basic Collection is an ordered set of items that can be referred to as a unit. |
| ComClassAttribute | The ComClassAttribute attribute instructs the compiler to add metadata that allows a class to be exposed as a COM object. |
| Constants | The Constants module contains miscellaneous constants. These constants can be used anywhere in your code. |
| ControlChars | The ControlChars module contains constants used as control characters. These constants can be used anywhere in your code. |
| Conversion | The Conversion module contains the procedures used to perform various conversion operations. |
| DateAndTime | The DateAndTime module contains the procedures and properties used in date and time operations. |
| ErrObject | The ErrObject module contains properties and procedures used to identify and handle run-time errors using the Err object. |
| FileSystem | The FileSystem module contains the procedures that are used to perform file, directory or folder, and system operations. The My feature gives you better productivity and performance in file I/O operations than using the FileSystem module. For more information, see My.Computer.FileSystem Object. |
| Financial | The Financial module contains procedures used to perform financial operations. |
| Globals | The Globals module contains script engine functions. |
| HideModuleNameAttribute | The HideModuleNameAttribute attribute, when applied to a module, allows the module members to be accessed using only the qualification needed for the module. |

| Interaction | The Interaction module contains procedures used to interact with objects, applications, and systems. |
| MyGroupCollectionAttribute | This attribute supports My.Forms and My.WebServices in Visual Basic. |
| Strings | The Strings module contains procedures used to perform string operations. |
| VBCodeProvider | Provides access to instances of the Visual Basic code generator and code compiler. |
| VBFixedArrayAttribute | Indicates that an array in a structure or non-local variable should be treated as a fixed-length array. |
| VBFixedStringAttribute | Indicates that a string should be treated as if it were fixed length. |
| VBMath | The VbMath module contains procedures used to perform mathematical operations. |
| | Structure | Description |
|---|
 | SpcInfo | This class supports the Visual BasicPrint and PrintLine functions. |
| TabInfo | This class supports the Visual BasicPrint and PrintLine functions. |
| | Enumeration | Description |

| AudioPlayMode | Indicates how to play sounds when calling audio methods. |
| CallType | Indicates the type of procedure being invoked when calling the CallByName function. |

| DueDate | Indicates when payments are due when calling financial methods. |
| FileAttribute | Indicates the file attributes to use when calling file-access functions. |
| FirstDayOfWeek | Indicates the first day of the week to use when calling date-related functions. |
| FirstWeekOfYear | Indicates the first week of the year to use when calling date-related functions. |
| MsgBoxResult | Indicates which button was pressed on a message box, returned by the MsgBox function. |
| MsgBoxStyle | Indicates which buttons to display when calling the MsgBox function. |
| OpenAccess | Indicates how to open a file when calling file-access functions. |
| OpenMode | Indicates how to open a file when calling file-access functions. |
| OpenShare | Indicates how to open a file when calling file-access functions. |
| TriState | Indicates a Boolean value or whether the default should be used when calling number-formatting functions. |
