制作过程：

1．在MDB文件的相同文件夹下放上一个图片文件，假定文件名为ico.ico。

2．有一个窗体frmopen，并设为启动窗体。

在窗体frmopen的打开事件中写代码：

Private Sub Form_Open(Cancel As Integer)
    '更改窗体图标
    SetFormicon Me.hWnd, CurrentProject.Path & "\ico.ico"
    '更改系统标题及图标
    Dim intX As Integer
    Const DB_Text As Long = 10
    intX = AddAppProperty("AppTitle", DB_Text, "我是修改的窗体名称！！！")
    intX = AddAppProperty("Appicon", DB_Text, CurrentProject.Path & "\ico.ico")
    Application.RefreshTitleBar
    
End Sub

在模块中写代码：

Declare Function LoadImage Lib "User32" Alias "LoadImageA" (ByVal hInst As Long, ByVal lpsz As String, ByVal un1 As Long, ByVal n1 As Long, ByVal n2 As Long, ByVal un2 As Long) As Long

    hicon = LoadImage(0&, IconPath, IMAGE_ICON, 16, 16, LR_LOADFROMFILE)
    If hicon <> 0 Then
        Call SendMessage(hWnd, WM_SETICON, 0, ByVal hicon)

    Set dbs = CurrentDb
    On Error GoTo AddProp_Err
    dbs.Properties(strName) = varvalue
    AddAppProperty = True
AddProp_Bye:
    Exit Function
AddProp_Err:
    If Err = conPropNotFoundError Then
        Set prp = dbs.CreateProperty(strName, varType, varvalue)
        dbs.Properties.Append prp

    Else
        AddAppProperty = False
        Resume AddProp_Bye
    End If
