怎样关闭一个程序
你可以使用API函数FindWindow和PostMessage来寻找一个窗口并且关闭它。下面的范例演示如何关闭一个标题为"Calculator"的窗口。
Dim winHwnd As Long
Dim RetVal As Long
winHwnd = FindWindow(vbNullString, "Calculator")
Debug.Print winHwnd
If winHwnd <> 0 Then
RetVal = PostMessage(winHwnd, WM_CLOSE, 0&, 0&)
If RetVal = 0 Then
MsgBox "Error posting message."
End If
Else
MsgBox "The Calculator is not open."
End If
For this code to work, you must have declared the API functions in a module in your project. You must put the following in the declarations section of the module.
Declare Function FindWindow Lib "user32" Alias _
"FindWindowA" (ByVal lpClassName As String, _
ByVal lpWindowName As String) As Long
Declare Function PostMessage Lib "user32" Alias _
"PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, _
ByVal wParam As Long, lParam As Any) As Long
Public Const WM_CLOSE = &H10
*****************************************************************
如何使Form的背景图随Form大小改变
单纯显示图形用Image即可,而且用Image也正好可解决你的问题
设定Image的Stretch=true
在加入以下的code
Private Sub Form_Resize()
Image1.Move 0, 0, ScaleWidth, ScaleHeight
End Sub
或者使用以下的方式来做也可以
Private Sub Form_Paint()
Me.PaintPicture Me.Picture, 0, 0, ScaleWidth, ScaleHeight
End Sub
*************************************************************************
软件的注册
可用注册表简单地保存已用的天数或次数
'次数限制（如３０次）如下：
Private Sub Form_Load()
Dim RemainDay As Long
RemainDay = GetSetting("MyApp", "set", "times", 0)
If RemainDay = 30 Then
MsgBox "试用次数已满，请注册"
Unload Me
End If
MsgBox "现在剩下：" & 30 - RemainDay & "试用次数，好好珍惜！"
RemainDay = RemainDay + 1
SaveSetting "MyApp", "set", "times", RemainDay
End Sub
'时间限制的（如３０天）
Private Sub Form_Load()
Dim RemainDay As Long
RemainDay = GetSetting("MyApp", "set", "day", 0)
If RemainDay = 30 Then
MsgBox "试用期已过，请注册"
Unload Me
End If
MsgBox "现在剩下：" & 30 - RemainDay & "试用天数，好好珍惜！"
if day(now)-remainday>0 then RemainDay = RemainDay + 1
SaveSetting "MyApp", "set", "times", RemainDay

通用对话框专辑（全）
使用API调用Winodws各种通用对话框(Common Diaglog)的方法（一）
1.文件属性对话框
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 '可选参数
lpClass As String '可选参数
hkeyClass As Long '可选参数
dwHotKey As Long '可选参数
hIcon As Long '可选参数
hProcess As Long '可选参数
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
'打开指定文件的属性对话框,如果返回值<=32则出错
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
新建一个工程,添加一个按钮和名为Text1的文本框
把以下代码置入CommandbButton_Click 中
Dim r As Long
Dim fname As String
'从Text1 中获取文件名及路径
fname = (Text1)
r = ShowProperties(fname, Me.hwnd)
If r <= 32 Then MsgBox "Error"
2.使用Win95的关于对话框
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.调用"捕获打印机端口"对话框
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.调用颜色对话框
Private Type ChooseColor
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
将以下代码置入某一事件中:
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.调用复制磁盘对话框
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:
向窗体中添加一个名为Drive1的DriveListBox,将以下代码置入某一事件中
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.调用格式化软盘对话框
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
参数设置:
fmtID-
3.5" 5.25"

0 快速
1 完全
2 只复制系统文件
3 只复制系统文件

9 完全
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

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")
