vb.net最小化到托盤 vb窗體最小化按鈕不可用怎么設(shè)置

vb.net怎么把其它程序最小化到托盤

如果用vb.net程序打開可以用如下代碼:

Shell("C:\文件",?AppWinStyle.Hide)'打開C:\文件,并在其打開時(shí)將其隱藏

如不懂可以追問

望采納

vb.net 利用NotifyIcon實(shí)現(xiàn)最小化到系統(tǒng)托盤,但是收縮到軌跡到開始菜單

添加托盤圖標(biāo)控件,并設(shè)置好其Icon屬性,然后添加如下代碼:

Private Sub Form1_FormClosing(sender As Object, e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing

e.Cancel = True

Me.Hide()

End Sub

這樣實(shí)現(xiàn)了點(diǎn)關(guān)閉,進(jìn)入托盤,如果點(diǎn)最小化進(jìn)入托盤:

'窗體最小化時(shí)候隱藏窗體,

Private Sub MainForm_SizeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.SizeChanged

If Me.WindowState = FormWindowState.Minimized Then

Me.Hide()

Me.ShowInTaskbar = False

End If

End Sub

vb中怎么最小化系統(tǒng)托盤

首先添加一個(gè)模塊,寫入代碼,代碼我已經(jīng)準(zhǔn)備好了

然再給Form窗體添加代碼

模塊

Option Explicit

Public Const MAX_TOOLTIP As Integer = 64

Public Const NIF_ICON = H2

Public Const NIF_MESSAGE = H1

Public Const NIF_TIP = H4

Public Const NIM_ADD = H0

Public Const NIM_DELETE = H2

Public Const WM_MOUSEMOVE = H200

Public Const WM_LBUTTONDOWN = H201

Public Const WM_LBUTTONUP = H202

Public Const WM_LBUTTONDBLCLK = H203

Public Const WM_RBUTTONDOWN = H204

Public Const WM_RBUTTONUP = H205

Public Const WM_RBUTTONDBLCLK = H206

Public Const SW_RESTORE = 9

Public Const SW_HIDE = 0

Public nfIconData As NOTIFYICONDATA

Public Type NOTIFYICONDATA

 cbSize As Long

Public Declare Function ShowWindow Lib "user32" (ByVal hWnd As Long, ByVal nCmdShow As Long) As Long

Public Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long

From窗體Private Sub Command1_Click()

With nfIconData

.hWnd = Me.hWnd

.uID = Me.Icon

.uFlags = NIF_ICON Or NIF_MESSAGE Or NIF_TIP

.uCallbackMessage = WM_MOUSEMOVE

.hIcon = Me.Icon.Handle

.szTip = App.Title + "(版本 " App.Major "." App.Minor "." App.Revision ")" vbNullChar

.cbSize = Len(nfIconData)

End With

Call Shell_NotifyIcon(NIM_ADD, nfIconData)

Me.Hide

End Sub

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)

End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)

Dim lMsg As Single

lMsg = X / Screen.TwipsPerPixelX

Select Case lMsg

Case WM_LBUTTONUP

End Select

End Sub

vb.net點(diǎn)關(guān)閉 最小化到托盤

添加托盤圖標(biāo)控件,并設(shè)置好其Icon屬性,然后添加如下代碼:

Private Sub Form1_FormClosing(sender As Object, e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
