WallPaper

How can I set the windows wallpaper to my picture by VB code?

THANK YOU!

Try this:

Code:

---

Private Declare Function GetPrivateProfileString _
Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal _
lpApplicationName As String, ByVal lpKeyName As String, _
ByVal lpDefault As String, ByVal lpReturnedString As _
String, ByVal nSize As Long, ByVal lpFileName As String) As _
Long

Private Function ReadINI(strsection As String, strkey As String, strfullpath As String) As String
  Dim strbuffer As String
  Let strbuffer$ = String$(750, Chr$(0&))
  Let ReadINI$ = Left$(strbuffer$, GetPrivateProfileString(strsection$, ByVal LCase$(strkey$), "", strbuffer, Len(strbuffer), strfullpath$))
End Function

Private Sub Form_Load()
    Picture1.Picture = LoadPicture(ReadINI("Desktop", "Wallpaper", "C:\Windows\Win.INI"))
End Sub

I'm sorry, Matthew.
In reality I want to set my picture to the windows wallpaper.
I want to change the windows wallpaper, by VB code.

Thank you!

Code:

Private Declare Function WritePrivateProfileString _
Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal _
lpApplicationName As String, ByVal lpKeyName As Any, ByVal _
lpString As Any, ByVal lpFileName As String) As Long

Private Sub WriteINI(strsection As String, strkey As String, strkeyvalue As String, strfullpath As String)
    Call WritePrivateProfileString(strsection$, UCase$(strkey$), strkeyvalue$, strfullpath$)
End Sub


Private Sub Form_Load()
    Call WriteINI("Desktop", "Wallpaper", "C:\MyPic.bmp", "C:\Windows\Win.INI")
End Sub

Hey Matthew when you are writing to the Win.ini file you can just use the WriteProfileString function....

Code:

---


Option Explicit

Private Declare Function WriteProfileString Lib "kernel32" Alias "WriteProfileStringA" (ByVal lpszSection As String, ByVal lpszKeyName As String, ByVal lpszString As String) As Long

Private Sub WriteWinINI(strsection As String, strkey As String, strkeyvalue As String)
    Call WriteProfileString(strsection$, UCase$(strkey$), strkeyvalue$)
End Sub


Private Sub Form_Load()
    Call WriteWinINI("Desktop", "Wallpaper", "C:\Windows\Forest.bmp")
End Sub

Thank you, guys, by your attention. But it doesn't work.
I changed the win.ini file (by your code) but it doesn't changed the Register (in Register Editor).
I think that is missing something.
