'Declaration
Function EnumHiddenRegions ( _
    dwFindFlags As UInteger, _

) As Integer
'Usage
Dim instance As IVsHiddenTextSession 
Dim dwFindFlags As UInteger 
Dim dwCookie As UInteger 
Dim ptsRange As TextSpan()
Dim ppEnum As IVsEnumHiddenRegions 
Dim returnValue As Integer 

returnValue = instance.EnumHiddenRegions(dwFindFlags, _
    dwCookie, ptsRange, ppEnum)
int EnumHiddenRegions(
    uint dwFindFlags,
    uint dwCookie,
    TextSpan[] ptsRange,
    out IVsEnumHiddenRegions ppEnum
)
int EnumHiddenRegions(
    [InAttribute] unsigned int dwFindFlags, 
    [InAttribute] unsigned int dwCookie, 
    [InAttribute] array<TextSpan>^ ptsRange, 
    [OutAttribute] IVsEnumHiddenRegions^% ppEnum
)
function EnumHiddenRegions(
    dwFindFlags : uint, 
    dwCookie : uint, 
    ptsRange : TextSpan[], 
    ppEnum : IVsEnumHiddenRegions
) : int

Parameters

  • dwCookie
    Type: System.UInt32

    [in] Specifies the client-defined hidden region type to find. Specify a value that matches the client-defined identifier specified during the creation of the new hidden region (that is, the dwClient member in the NewHiddenRegion structure).

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsHiddenTextSession::EnumHiddenRegions(
   [in] DWORD dwFindFlags, 
   [in] DWORD_PTR dwCookie, 
   [in] TextSpan *ptsRange, 
   [out] IVsEnumHiddenRegions **ppEnum
);

IVsHiddenTextSession.EnumHiddenRegions returns a static snapshot list of hidden regions. There is a variety of Find options that you can specify, based on the value of the dwFindFlags parameter. These options include finding all regions, finding regions of a type matching that specified in the dwCookie parameter, and finding hidden regions that intersect or are fully contained by a particular span of text. For more information on the available options, see FIND_HIDDEN_REGION_FLAGS.
