1.文件屬性對話框
Type SHELLEXECUTEINFO
cbSize As Long
fMask As Long
hwnd As Long
lpVerb As String
lpFile As String
lpParameters As String
lpDirectory As String
nShow As Long
hInstApp As Long
lpIDList As Long '可選參數(shù)
lpClass As String '可選參數(shù)
hkeyClass As Long '可選參數(shù)
dwHotKey As Long '可選參數(shù)
hIcon As Long '可選參數(shù)

End Type
Const SEE_MASK_INVOKEIDLIST = &HC
Const SEE_MASK_NOCLOSEPROCESS = &H40
Const SEE_MASK_FLAG_NO_UI = &H400
Declare Function ShellExecuteEX Lib "shell32.dll" Alias "ShellExecuteEx" _
(SEI As SHELLEXECUTEINFO) As Long
Public Function ShowProperties(filename As String, OwnerhWnd As Long) As Long
'打開指定文件的屬性對話框,如果返回值<=32則出錯
Dim SEI As SHELLEXECUTEINFO
Dim r As Long
With SEI
.cbSize = Len(SEI)
.fMask = SEE_MASK_NOCLOSEPROCESS Or SEE_MASK_INVOKEIDLIST Or SEE_MASK_FLAG_NO_UI
.hwnd = OwnerhWnd
.lpVerb = "properties"
.lpFile = filename
.lpParameters = vbNullChar
.lpDirectory = vbNullChar
.nShow = 0
.hInstApp = 0
.lpIDList = 0
End With
r = ShellExecuteEX(SEI)
ShowProperties = SEI.hInstApp
End Function
新建一個工程,添加一個按鈕和名為Text1的文本框
把以下代碼置入CommandbButton_Click 中
Dim r As Long
Dim fname As String
'從Text1 中獲取文件名及路徑
fname = (Text1)
r = ShowProperties(fname, Me.hwnd)
If r <= 32 Then MsgBox "Error"
2.使用Win95的關(guān)于對話框
Private Declare Function ShellAbout Lib "shell32.dll" _
Alias "ShellAboutA" (ByVal hwnd As Long, ByVal szApp As String, _
ByVal szOtherStuff As String, ByVal hIcon As Long) As Long
示例:
Dim x As Long
x = shellabout (Form1.hwnd, "Visual Basic 6.0", _
"Alp Studio MouseTracker Ver 1.0", Form1.icon)
2.調(diào)用"捕獲打印機端口"對話框
Private Declare Function WNetConnectionDialog Lib "mpr.dll" _
(ByVal hwnd As Long, ByVal dwType As Long) As Long
示例:
Dim x As Long
x = WNetConnectionDialog(Me.hwnd, 2)
3.調(diào)用顏色對話框

lStructSize As Long
hwndOwner As Long
hInstance As Long
rgbResult As Long
lpCustColors As String
flags As Long
lCustData As Long
lpfnHook As Long
lpTemplateName As String
End Type
Private Declare Function ChooseColor Lib "comdlg32.dll" Alias "ChooseColorA" (pChoosecolor As ChooseColor) As Long
將以下代碼置入某一事件中:
Dim cc As ChooseColor
Dim CustColor(16) As Long
cc.lStructSize = Len(cc)
cc.hwndOwner = Form1.hWnd
cc.hInstance = App.hInstance
cc.flags = 0
cc.lpCustColors = String$(16 * 4, 0)
Dim a
Dim x
Dim c1
Dim c2
Dim c3
Dim c4
a = ChooseColor(cc)
Cls
If (a) Then
MsgBox "Color chosen:" & Str$(cc.rgbResult)
For x = 1 To Len(cc.lpCustColors) Step 4
c1 = Asc(Mid$(cc.lpCustColors, x, 1))
c2 = Asc(Mid$(cc.lpCustColors, x + 1, 1))
c3 = Asc(Mid$(cc.lpCustColors, x + 2, 1))
c4 = Asc(Mid$(cc.lpCustColors, x + 3, 1))
CustColor(x / 4) = (c1) + (c2 * 256) + (c3 * 65536) + (c4 * 16777216)
MsgBox "Custom Color " & Int(x / 4) & " = " & CustColor(x / 4)
Next x
Else
MsgBox "Cancel was pressed"
End If
4.調(diào)用復制磁盤對話框
Private Declare Function SHFormatDrive Lib "shell32" (ByVal hwnd As Long, ByVal Drive As Long, ByVal fmtID As Long, ByVal options As Long) As Long
Private Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long
示例:
向窗體中添加一個名為Drive1的DriveListBox,將以下代碼置入某一事件中
Dim DriveLetter$, DriveNumber&, DriveType&
Dim RetVal&, RetFromMsg&
DriveLetter = UCase(Drive1.Drive)
DriveNumber = (Asc(DriveLetter) - 65)
DriveType = GetDriveType(DriveLetter)
If DriveType = 2 Then 'Floppies, etc
RetVal = Shell("rundll32.exe diskcopy.dll,DiskCopyRunDll " _
& DriveNumber & "," & DriveNumber, 1) 'Notice space after
Else ' Just in case 'DiskCopyRunDll
RetFromMsg = MsgBox("Only floppies can" & vbCrLf & _
"be diskcopied!", 64, "DiskCopy Example")
End If
5.調(diào)用格式化軟盤對話框
Private Declare Function SHFormatDrive Lib "shell32" (ByVal hwnd As Long, ByVal Drive As Long, ByVal fmtID As Long, ByVal options As Long) As Long
Private Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long
參數(shù)設(shè)置:
fmtID-
3.5" 5.25"

示例:要求同上
Dim DriveLetter$, DriveNumber&, DriveType&
Dim RetVal&, RetFromMsg%
DriveLetter = UCase(Drive1.Drive)
DriveNumber = (Asc(DriveLetter) - 65) ' Change letter to Number: A=0
DriveType = GetDriveType(DriveLetter)
If DriveType = 2 Then 'Floppies, etc
RetVal = SHFormatDrive(Me.hwnd, DriveNumber, 0&, 0&)
Else
RetFromMsg = MsgBox("This drive is NOT a removeable" & vbCrLf & _
"drive! Format this drive?", 276, "SHFormatDrive Example")
Select Case RetFromMsg
Case 6 'Yes
' UnComment to do it...
'RetVal = SHFormatDrive(Me.hwnd, DriveNumber, 0&, 0&)
Case 7 'No
' Do nothing
End Select
End If
