Parameters

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

[in] Project to which the files will be added.

cFiles
Type: System.Int32

[in] Number of files to add. It is not valid for cFiles to be zero.

rgpszMkDocuments
Type: array<System.String[]

[in] Array of paths for the files to be added. This is the same size as cFiles.

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

[in] Array of flags associated with each file. For more information, 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.

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::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[]
);

Call this method when you want to add files to your project. This method must be called before the files are added to the project. The environment will return a flag indicating which files can be added. After you have received authorization to add the files and you have added the files, call OnAfterAddFilesEx or OnAfterAddFiles to confirm that the files have been added.
