如何 在 vb.net 中 按下鍵盤(pán)A與W 兩個(gè)按鍵組合時(shí)彈出 MsgBox("你按下了A+W鍵")，最好有例子程序。

樓上的按了一次A+W后,接下來(lái)單按W鍵就會(huì)彈出信息框

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鍵")

End If

End Sub

End Class

按照順序的話,這樣寫(xiě):

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鍵")

End If

End Sub

End Class

望采納~

VB.NET 窗口彈出問(wèn)題

你在第一個(gè)窗口里寫(xiě) Form2.ShowDialog()

這樣就可以了，關(guān)掉form2的時(shí)候form1的代碼就會(huì)繼續(xù)執(zhí)行

VB.net怎么彈出如下類(lèi)似的對(duì)話框（看圖）？

可以利用msgbox 實(shí)現(xiàn)，也可以通過(guò)另外的窗體上畫(huà)出表格實(shí)現(xiàn)

方法一，利用msgbox：

Private Sub Command1_Click()Dim a As Long, b As Long, c As LongMsgBox "┌────┬────┬────┐" vbCrLf _ "│ 庫(kù)存1 │ 庫(kù)存2 │ 庫(kù)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，利用窗體實(shí)現(xiàn)：

’新建form2窗體‘將以下代碼復(fù)制到form2窗體中Private Sub Form_Load()ShowPrint "┌────┬────┬────┐" vbCrLf _ "│ 庫(kù)存1 │ 庫(kù)存2 │ 庫(kù)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‘將以下代碼復(fù)制在form1窗體中Private Sub Command1_Click()Form2.ShowEnd Sub
