abstract EnumHiddenRegions : 
        dwFindFlags:uint32 *

        ppEnum:IVsEnumHiddenRegions byref -> int

function EnumHiddenRegions(
    dwFindFlags : uint, 
    dwCookie : uint, 
    ptsRange : TextSpan[], 
    ppEnum : IVsEnumHiddenRegions
) : int

Parameters

dwFindFlags
Type: System.UInt32
[in] Options for finding hidden regions. For more information, see FIND_HIDDEN_REGION_FLAGS.

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).

ptsRange
Type: array<Microsoft.VisualStudio.TextManager.Interop.TextSpan[]
[in] Specifies the range of text over which to enumerate the hidden regions.

ppEnum
Type: Microsoft.VisualStudio.TextManager.Interop.IVsEnumHiddenRegions%
[out] Pointer to an IVsEnumHiddenRegions object that is used to enumerate hidden regions of specified type over the specified range in the text buffer.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

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.
