Private Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As LongPrivate Const WS_EX_LAYERED = H80000

Private Const GWL_EXSTYLE = (-20)

Private Const LWA_ALPHA = H2

Private Const LWA_COLORKEY = H1Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long

Private Const HWND_TOPMosT = -1

Private Const SWP_NOMOVE = H2

Private Const SWP_NosIZE = H1

Private Declare Function GetForegroundWindow Lib "user32" () As Long

Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Const WM_KEYDOWN = H100

Const WM_KEYUP = H101

Const WM_CHAR = H102

Const VK_F1 = H70

Private Sub SendF1(hwnd) '调用这个过程即可对目标窗体发送F1键

Call PostMessage(hwnd, WM_KEYDOWN, VK_F1, 0)

Call PostMessage(hwnd, WM_KEYUP, VK_F1, 0)

End Sub这里是发送F1的实例,各个按键对应的虚拟键码,要到网上查

VB.NET可以制作游戏吗?

可以

做中小游戏

但它有个缺点,游戏比专业软件开发的运行速度要慢

大游戏,最好使用专业游戏开发软件

VB.net制作启动界面

新建一个Sub : Main

Private Sub Main()

xxx.show 'xxx指启动窗体

'载入图片、数据库之类的

Unload xxx

{from}.show '{from}指主界面

End Sub

然后在工程-属性将"Main"作为启动对象

用VB.NET制作相册

假设有三张图片在资源里,VB.NET不允许资源的名字是纯数字,假设取名Image1,Image2......

Dim Images() As System.Drawing.Bitmap = {My.Resources.Image1, My.Resources.Image2, My.Resources.Image3}

Dim CurrentImage As Integer

Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click

If CurrentImage 2 Then CurrentImage += 1 Else CurrentImage = 0

PictureBox1.Image = Images(CurrentImage)

End Sub

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

If CurrentImage 0 Then CurrentImage -= 1 Else CurrentImage = 2

PictureBox1.Image = Images(CurrentImage)

End Sub

vb.net 如何制作多图动画 最好用循环语句~

很简单啊,软糖给你代码

For i = 1 To 9999

Dim 名称 As String = String.Format("Img{0}.png", 编号) '会返回Img1.png,Img2.png...

picturebox1.Image = Bitmap.FromFile(名称)

Next

满意请采纳,谢谢。
