IShellFolderParseDisplayName Method

Translates the display name of a file object or a folder into an item identifier list.

Definition

Namespace: DevCase.Win32.Interfaces
Assembly: DevCase.net48 (in DevCase.net48.dll) Version: 6.0.0.0 (6.0)
XMLNS for XAML: Not mapped to an xmlns.
void ParseDisplayName(
	IntPtr hwnd,
	[OptionalAttribute] IBindCtx bindContext,
	string displayName,
	ref uint refEaten,
	ref PIDL refPidl,
	out ShellItemAttributesMask refAttributes
)

Parameters

hwnd  IntPtr
A window handle. The client should provide a window handle if it displays a dialog or message box. Otherwise set hwnd to NULL.
bindContext  IBindCtx  (Optional)
Optional. A pointer to a bind context used to pass parameters as inputs and outputs to the parsing function.

These passed parameters are often specific to the data source and are documented by the data source owners. For example, the file system data source accepts the name being parsed (as a WIN32_FIND_DATA structure), using the STR_FILE_SYS_BIND_DATA bind context parameter.

STR_PARSE_PREFER_FOLDER_BROWSING can be passed to indicate that URLs are parsed using the file system data source when possible.

Construct a bind context object using CreateBindCtx and populate the values using IBindCtx::RegisterObjectParam.

If no data is being passed to or received from the parsing function, this value can be NULL.

displayName  String
A null-terminated Unicode string with the display name.

Because each Shell folder defines its own parsing syntax, the form this string can take may vary.

The desktop folder, for instance, accepts paths such as "C:\My Docs\My File.txt".

It also will accept references to items in the namespace that have a GUID associated with them using the "::{GUID}" syntax.

refEaten  UInt32
A pointer to a value that receives the number of characters of the display name that was parsed.

If your application does not need this information, set refEaten to NULL, and no value will be returned.

refPidl  PIDL
When this method returns, contains a pointer to the PIDL for the object.

The returned item identifier list specifies the item relative to the parsing folder.

If the object associated with displayName is within the parsing folder, the returned item identifier list will contain only one SHITEMID structure.

If the object is in a subfolder of the parsing folder, the returned item identifier list will contain multiple SHITEMID structures.

If an error occurs, NULL is returned in this address.

When it is no longer needed, it is the responsibility of the caller to free this resource by calling CoTaskMemFree.

refAttributes  ShellItemAttributesMask
The value used to query for file attributes.

If not used, it should be set to NULL. To query for one or more attributes, initialize this parameter with the ShellItemAttributesMask flags that represent the attributes of interest. On return, those attributes that are and were requested will be set.
