int OnQueryRemoveDirectories(
    [InAttribute] IVsProject^ pProject, 
    [InAttribute] int cDirectories, 
    [InAttribute] array<String^>^ rgpszMkDocuments, 
    [InAttribute] array<VSQUERYREMOVEDIRECTORYFLAGS>^ rgFlags, 
    [OutAttribute] array<VSQUERYREMOVEDIRECTORYRESULTS>^ pSummaryResult,

function OnQueryRemoveDirectories(
    pProject : IVsProject, 
    cDirectories : int, 
    rgpszMkDocuments : String[], 
    rgFlags : VSQUERYREMOVEDIRECTORYFLAGS[], 
    pSummaryResult : VSQUERYREMOVEDIRECTORYRESULTS[], 
    rgResults : VSQUERYREMOVEDIRECTORYRESULTS[]
) : int

Parameters

pProject
Type: Microsoft.VisualStudio.Shell.Interop.IVsProject

[in] Project containing the directories to remove.

cDirectories
Type: System.Int32

[in] Number of directories to remove.

rgpszMkDocuments
Type: array<System.String[]

[in] Array of paths for the directories to remove.

rgFlags
Type: array<Microsoft.VisualStudio.Shell.Interop.VSQUERYREMOVEDIRECTORYFLAGS[]

[in] Array of directory removal flags. For a list of rgFlags values, see VSQUERYREMOVEDIRECTORYFLAGS

pSummaryResult
Type: array<Microsoft.VisualStudio.Shell.Interop.VSQUERYREMOVEDIRECTORYRESULTS[]

[out] ] Summary result object. This object is a summation of the yes and no results for the array of directories passed in rgpszMkDocuments. If the result for a single directory is no, then pSummaryResult is equal to VSQUERYREMOVEDIRECTORYRESULTS_RemoveNotOK; if the results for all files are yes, then pSummaryResult is equal to VSQUERYREMOVEDIRECTORYRESULTS_RemoveOK. For a list of pSummaryResult values, see VSQUERYREMOVEDIRECTORYRESULTS.

rgResults
Type: array<Microsoft.VisualStudio.Shell.Interop.VSQUERYREMOVEDIRECTORYRESULTS[]

[out] Array of results[]. For a list of rgResults values, see VSQUERYREMOVEDIRECTORYRESULTS.

Note If you pass in nulla null reference (Nothing in Visual Basic) for this parameter, then only the summary result will be returned (pSummaryResult).

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 IVsTrackProjectDocuments2.idl

HRESULT IVsTrackProjectDocuments2::OnQueryRemoveDirectories(
   [in] IVsProject *pProject,
   [in] int cDirectories,
   [in, size_is(cDirectories)] const LPCOLESTR rgpszMkDocuments[],
   [in, size_is(cDirectories)] const VSQUERYREMOVEDIRECTORYFLAGS rgFlags[],
   [out] VSQUERYREMOVEDIRECTORYRESULTS *pSummaryResult,

);

Call this method when you want to remove directories from the project. This method must be called before the directories are removed. The environment will return a flag indicating which directories can be removed. After you have received authorization to remove the directories and you have removed them, call OnAfterRemoveDirectories to confirm that the directories have been removed.

Note

All directory calls are optional. However, if you call one of the OnQuery* directory methods, then you are required to call the corresponding OnAfter* directory method if the OnQuery* call was successful.
