Members
| Member name | Description | |
|---|---|---|
| VSQEQS_FileInfo | Specifies whether the file attributes are valid. This value is used for optimization and indicates that the members of the corresponding VSQEQS_FILE_ATTRIBUTE_DATA structure are valid, thus avoiding having to query the disk for file attributes. A caller can use this value if it has recent file information; otherwise, leave the flag un-set, and when you call QueryEditFiles, QuerySaveFile, or QuerySaveFiles, this information will be provided. Use the SVsQueryEditQuerySave service to access these methods. | |
| VSQEQS_AllowCheckout | Deprecated flag: ignored. | |
| VSQEQS_NoSaveAs | Deprecated flag: ignored. |
Remarks
VSQEQS_FileInfo is an optimization. It indicates that the members of the corresponding VSQEQS_FILE_ATTRIBUTE_DATA are valid and thus a call to FindFirstFile (or GetFileAttributesEx on NT) is unnecessary. A caller can use this if it has "recent" file information; otherwise SVsQueryEditQuerySave acquires the information.
