_VSRDTFLAGS Enumeration

Specifies options for a document in the running document table (RDT).

Namespace: Microsoft.VisualStudio.Shell.Interop
Assembly: Microsoft.VisualStudio.Shell.Interop (in

public enum _VSRDTFLAGS
/** @attribute FlagsAttribute() */ 
public enum _VSRDTFLAGS
public enum _VSRDTFLAGS

 Member nameDescription
RDT_CanBuildFromMemoryIndicates that a save of the document is not forced on a build.  
RDT_CantSaveCombination of RDT_DontSave and RDT_DontSaveAs flags.  
RDT_CaseSensitiveWhen comparing MkDocument strings, perform a case-sensitive comparison of the strings. 
RDT_DOCMASKMask of the flags from RDT_DontSaveAs through RDT_DontAddToMRU. Allow __VSCREATEDOCWIN flags in doc mask.  
RDT_DontAddToMRUDo not add to the list of most recently used files.  
RDT_DontAutoOpenIndicates that the document is not persisted in the list of documents that can be opened when the solution is re-opened. Such a document would not be opened using an editor factory, but might be opened using a wizard or special programmatic code.  
RDT_DontSaveAny document marked with this value is not included in the list of documents shown in the SaveChanges dialog box. The Save Changes dialog box is displayed when the user selects Exit from the File menu.  
RDT_DontSaveAsIndicates that the SaveAs command should not be made available for this document.  
RDT_EditLockPlaces an edit lock on the document  
RDT_LOCKMASKMask of the RDT_NoLock, RDT_ReadLock, RDT_EditLock, and RDT_RequestUnlock flags.  
RDT_NoLockIndicates that no lock is placed on the document.  
RDT_NonCreatableIndicates that the document is created through some special programmatic means. For example, using a wizard. If you specify the RDT_NonCreatable flag, then the RDT_DontAutoOpen flag automatically applies to your document.  
RDT_PlaceHolderDocUsed in the implementation of miscellaneous files. Prevents the Miscellaneous Files project from calling the CreateDocumentWindow method on the document added to the project.  
RDT_ProjSlnDocumentSet automatically by the environment when a solution or project is opened. Used to flag solution and project files in the running document table. Clients are required to set this flag in the case of nested projects.  
RDT_ReadLockPlaces a read lock on the document.  
RDT_RequestUnlockRequests an unlock of the document.  
RDT_SAVEMASKMask of the RDT_Unlock_NoSave, RDT_Unlock_SaveIfDirty, and RDT_Unlock_PromptSave flags.  
RDT_Unlock_NoSaveUsed by UnlockDocument. Release the edit lock and do not save.  
RDT_Unlock_PromptSaveUsed by the UnlockDocument method. Release the edit lock and prompt the user to save the file.  
RDT_Unlock_SaveIfDirtyUsed by the UnlockDocument method. Release the edit lock and save the file if it is dirty.  
RDT_VirtualDocumentExclude this document from being considered in the documents collection for the automation model.

This enumeration is used by a number of methods in the IVsRunningDocumentTable, IVsRunningDocTableEvents, IVsRunningDocTableEvents2, and the IVsRunningDocTableEvents3 interfaces.

These flags are also used in combination with flags from the __VSOSPEFLAGS enumeration when passed to the OpenSpecificEditor method.

The flags masked by the RDT_DOCMASK value can also be combined with flags from the __VSCREATEDOCWIN enumeration when creating a document window in calls to the CreateDocumentWindow, AddDocument (IVsExternalFilesManager interface), AddDocument (IVsExternalFilesManager2 interface), and AddDocumentEx methods.
