I'm using SHGetFileInfo api call from VB.NET so as to retreive icon
associated of a file. I want also to get "type of file" string with
SHGFI_TYPENAME flag but I can't see nothing. When I call api function and I
look for szTypeName all I get is a null string.
Quick and dirty:
\\\
Imports System.Runtime.InteropServices
Public Class Form1
Inherits System.Windows.Forms.Form
Private Declare Auto Function SHGetFileInfo Lib "shell32.dll" ( _
ByVal pszPath As String, _
ByVal dwFileAttributes As Integer, _
ByRef psfi As SHFILEINFO, _
ByVal cbFileInfo As Integer, _
ByVal uFlags As Integer _
) As IntPtr
<StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Auto)> _
Private Structure SHFILEINFO
Public hIcon As Int32
Public iIcon As Int32
Public dwAttributes As Int32
<MarshalAs(UnmanagedType.ByValTStr, SizeConst:=260)> _
Public szDisplayName As String
<MarshalAs(UnmanagedType.ByValTStr, SizeConst:=80)> _
Public szTypeName As String
End Structure
Private Const SHGFI_TYPENAME As Int32 = &H400
Private Sub Form1_Load( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs _
) Handles MyBase.Load
Dim x As SHFILEINFO
Call SHGetFileInfo("C:\test_tl\ausarb.tex", 0, x, Len(x), SHGFI_TYPENAME)
MsgBox(x.szTypeName)
End Sub
End Class
