__UserSettingsFlags Enum

Definition

Used by the integrated development environment (IDE) to define how imported settings are handled.

This enumeration supports a bitwise combination of its member values.

public enum class __UserSettingsFlags

Fields

USF_DisableOptimizations 2

Specifies that a VSPackage should disable optimizations.

USF_None 0

Specifies that a VSPackage is free to either reset settings with valid imported values, or to treat settings import as an additive or merge operation.

USF_ResetOnImport 1

Specifies that a VSPackage should overwrite any existing settings with valid imported settings.

Remarks

The IDE passes registered implementations of ImportSettings flags constructed from __UserSettingsFlags to communicate user preferences during the Import/Export Settings operations.

For example, consider a setting that is a list. The current setting has the members A, B, and C. The settings to be retrieved contain the values D and E. When ImportSettings is called:

  • If the USF_ResetOnImport is used, the implementation of ImportSettings must overwrite the existing settings with D and E.

  • If the USF_None is used, the implementation of ImportSettings is free to

    1. Overwrite the existing settings with D and E.

    -or-

    1. Merge the imported data with the current data, in this case create a new list containing A, B, C, D, and E.
