Parameters

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

[in] Project requesting to add files.

cFiles
Type: System.Int32

[in] Number of files to add.

rgpszMkDocuments
Type: array<System.String[]

[in] Array of files to add to the project.

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

[in] Array of flags associated with each file. For a list of rgFlags values, see VSQUERYADDFILEFLAGS.

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

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

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

[out] Array of results for each individual file. For a list of rgResults values, see VSQUERYADDFILERESULTS.

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 IVsTrackProjectDocumentsEvents2.idl

HRESULT IVsTrackProjectDocumentsEvents2::OnQueryAddFiles(
   [in] IVsProject *pProject,
   [in] int cFiles,
   [in, size_is(cFiles)] const LPCOLESTR rgpszMkDocuments[],
   [in, size_is(cFiles)] const VSQUERYADDFILEFLAGS rgFlags[],
   [out] VSQUERYADDFILERESULTS *pSummaryResult,
   [out, size_is(cFiles)] VSQUERYADDFILERESULTS rgResults[]
);

Use IVsTrackProjectDocumentEvents2.OnQueryAddFiles to indicate whether specified files can be added to the project. Only deny a query if allowing the operation would compromise your stable state. For example, source control denies add queries if a file being added conflicts with an existing file already under source control.
