VB.net怎么弹出如下类似的对话框(看图)?

可以利用msgbox 实现,也可以通过另外的窗体上画出表格实现

方法一,利用msgbox:

Private Sub Command1_Click()Dim a As Long, b As Long, c As LongMsgBox "┌────┬────┬────┐" vbCrLf _ "│ 库存1 │ 库存2 │ 库存3 │" vbCrLf _ "├────┼────┼────┤" vbCrLf _ "│" formatstr(a) "│" formatstr(b) "│" formatstr(c) "│" vbCrLf _ "└────┴────┴────┘" End SubPrivate Function formatstr(ByVal inputStr As String) As StringDim j As Integerj = (8 - Len(inputStr)) \ 2formatstr = Space(j) inputStr Space(j) Space((8 - Len(inputStr)) Mod 2)End Function

方法二,利用窗体实现:

’新建form2窗体‘将以下代码复制到form2窗体中Private Sub Form_Load()ShowPrint "┌────┬────┬────┐" vbCrLf _ "│ 库存1 │ 库存2 │ 库存3 │" vbCrLf _ "├────┼────┼────┤" vbCrLf _ "│" formatstr(a) "│" formatstr(b) "│" formatstr(c) "│" vbCrLf _ "└────┴────┴────┘" End SubPrivate Function formatstr(ByVal inputStr As String) As StringDim j As Integerj = (8 - Len(inputStr)) \ 2formatstr = Space(j) inputStr Space(j) Space((8 - Len(inputStr)) Mod 2)End Function‘将以下代码复制在form1窗体中Private Sub Command1_Click()Form2.ShowEnd Sub

如何 在 vb.net 中 按下键盘A与W 两个按键组合时弹出 MsgBox("你按下了A+W键"),最好有例子程序。

楼上的按了一次A+W后,接下来单按W键就会弹出信息框

Public Class Form1

Private Declare Function GetAsyncKeyState Lib "user32.dll" (ByVal keyCode As Integer) As Short

Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown

If GetAsyncKeyState(Keys.A) And GetAsyncKeyState(Keys.W) Then

MsgBox("你按下了A+W键")

End If

End Sub

End Class

按照顺序的话,这样写:

Public Class Form1

Private Declare Function GetAsyncKeyState Lib "user32.dll" (ByVal keyCode As Integer) As Short

Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown

If GetAsyncKeyState(Keys.A) And e.KeyCode = Keys.W Then

MsgBox("你按下了A+W键")

End If

End Sub

End Class

望采纳~

vb.net 怎么让 win10 弹出系统通知

自己创建个无边框窗体 控制下显示位置 不就好了

样式图标随你设计

VB.NET 窗口弹出问题

你在第一个窗口里写 Form2.ShowDialog()

这样就可以了,关掉form2的时候form1的代码就会继续执行
