pinvoke.net: Edit: Structures.STRRET

Summary: TODO - a short description

The example given previously was incorrect - the cStr member should be an array of MAX_PATH (260) bytes, not a single IntPtr. I've added the Size=264 parameter to the StructLayout attribute to make this work. I know this is right in C#, have no idea about VB.

!!!!C# Definition:
 [StructLayout(LayoutKind.Explicit, Size=264)]
 public struct STRRET
 {
     [FieldOffset(0)]
     public UInt32 uType;	// One of the STRRET_* values

[FieldOffset(4)]
     public IntPtr pOleStr;	// must be freed by caller of GetDisplayNameOf

[FieldOffset(4)]
     public IntPtr pStr;		// NOT USED

[FieldOffset(4)]
     public UInt32 uOffset;	// Offset into SHITEMID

[FieldOffset(4)]
     public IntPtr cStr;		// Buffer to fill in (ANSI)
 }
!!!!VB Definition:
     <StructLayout(LayoutKind.Explicit, Size=264)> _
     Public Structure STRRET
         <FieldOffset(0)> Public uType As UInt32     'One of the STRRET_* values
         <FieldOffset(4)> Public pOleStr As IntPtr   'must be freed by caller of GetDisplayNameOf
         <FieldOffset(4)> Public pStr As IntPtr      'NOT USED
         <FieldOffset(4)> Public uOffset As UInt32   'Offset into SHITEMID
         <FieldOffset(4)> Public cString As IntPtr   'Buffer to fill in (ANSI)
     End Structure
!!!!User-Defined Field Types:
None.

!!!!Notes:
 Example:
 // Structure used to return the display name to
 STRRET pDisplayName;
 String DisplayName;
 SHFILEINFO m_shfi = new SHFILEINFO();

// Request the string as a char although Windows will likely ignore
 // the request.
 pDisplayName.uType = (uint)STRRET_TYPE.STRRET_CSTR;

// Get the "normal" display name.
 iShellFolder.GetDisplayNameOf(pidlItems[0], SHGNO.SHGDN_NORMAL, 
                 out pDisplayName);
 System.Text.StringBuilder sbDisplayName = new System.Text.StringBuilder(256);
 // Get the display name from the STRRET structure
 WindowsAPI.StrRetToBuf(ref pDisplayName, pidlItems[0], 
                sbDisplayName, (uint)sbDisplayName.Capacity);
 DisplayName = sbDisplayName.ToString();

!!!!Question
These codes are correct in 64bit platforms?
The size of STRRET sturctre in 64bit is 272 bytes.
