Definition

Open a previously created structured file data element and returns a pointer to the format index, data element, and pointer to a string containing the format version.

int OpenExisting(std::wstring const & szFileName, unsigned int dwShareMode, unsigned int dwCreationDisposition, unsigned int dwFlagsAndAttributes, Microsoft::VisualStudio::Shell::Interop::IVsStructuredFileIOHelper const & pIVsStructuredFileIOHelper, [Runtime::InteropServices::Out] unsigned int & pnFormatIndex, [Runtime::InteropServices::Out] Microsoft::VisualStudio::Shell::Interop::IVsPropertyFileIn const & & ppIVsPropertyFileIn, std::Array <std::wstring const &> const & pbstrFormatVersion);
public int OpenExisting (string szFileName, uint dwShareMode, uint dwCreationDisposition, uint dwFlagsAndAttributes, Microsoft.VisualStudio.Shell.Interop.IVsStructuredFileIOHelper pIVsStructuredFileIOHelper, out uint pnFormatIndex, out Microsoft.VisualStudio.Shell.Interop.IVsPropertyFileIn ppIVsPropertyFileIn, string[] pbstrFormatVersion);
abstract member OpenExisting : string * uint32 * uint32 * uint32 * Microsoft.VisualStudio.Shell.Interop.IVsStructuredFileIOHelper * uint32 * IVsPropertyFileIn * string[] -> int
Public Function OpenExisting (szFileName As String, dwShareMode As UInteger, dwCreationDisposition As UInteger, dwFlagsAndAttributes As UInteger, pIVsStructuredFileIOHelper As IVsStructuredFileIOHelper, ByRef pnFormatIndex As UInteger, ByRef ppIVsPropertyFileIn As IVsPropertyFileIn, Optional pbstrFormatVersion As String()) As Integer
