vb.net屏幕分辨率 windows屏幕分辨率

.NET (C#,VB也行)调用API使窗口大小能够超过屏幕分辨率要怎么做???

首先你要熟悉API函数,具体用哪些函数就不记得了~~~~~

我们提供的服务有:成都网站设计、成都网站制作、微信公众号开发、网站优化、网站认证、庐江ssl等。为成百上千企事业单位解决了网站和推广的问题。提供周到的售前咨询和贴心的售后服务,是有科学管理、有技术的庐江网站制作公司

其次,把你要用到API函数引用到代码中来,就可以用了啊

VB里貌似这段代码挺多的,需要好好研究

C#中,可以通过

winform窗体分辨率问题解决方案:

你也可以选择使用TableLayoutPanel等控件作为容器,把其他的控件放入Panel中,这个控件会使其中包含的控件随着程序环境的变化而变化。

注:TableLayoutPanel和Panel控件的DOCK属性应该都设为:fill。

的方法来实现~~~~~~~~~~·

VB6设置快捷键自我关闭程序和更改屏幕分辨率时自动调整窗体位置。

Option Explicit

'将屏幕长度(高度)的总缇数处以水平(Screen.TwipsPerPixelX)

'或垂直(Screen.TwipsPerPixelY)度量对象的每一像素缇数,就得到了相应方向的像素数。

'分别定义初始时候的屏幕宽和高,以及工程的宽和高

Dim pk As Single, pg As Single, fw As Single, fh As Single

Private Sub Command1_Click()

Dim x, y

x = Screen.Width / Screen.TwipsPerPixelX

y = Screen.Height / Screen.TwipsPerPixelY

MsgBox "你的电脑分辨率是 " x "*" y

End

End Sub

Private Sub Command2_Click() ' 让程序鼠标怎么按都没有用

Me.Enabled = False

End Sub

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer) '按F6退出

If KeyCode = vbKeyF6 Then Unload Me

End Sub

Private Sub Form_Load()

fw = Me.Width

fh = Me.Height

pk = Screen.Width

pg = Screen.Height

Timer1.Interval = 1000

End Sub

'我记得有个API函数的,可是具体的方法不记得了。所以就用一个timer来实时监控分辨率的··

'Set ddSet = dxSet.DirectDrawCreate("")

'dxSet建立DirectDraw对象ddSet

'ddSet.SetCooperativeLevel Me.hWnd, DDSCL_NORMAL

'设置协作水平

'Set DisModesEnum = ddSet.GetDisplayModesEnum(DDEDM_DEFAULT, dds2)

'DisModesEnum获得支持的显示模式

Private Sub Timer1_Timer()

If Screen.Width pk Or Screen.Height pg Then

Me.Width = fw / pk * Screen.Width

Me.Height = fh / pg * Screen.Height

End If

End Sub

在VB.NET中通过那个函数可以获取当前屏幕的分辨率?

您可以用下面给出这一小段代码检测当前屏幕分辨率,然后根据结果作出反应──例如,重新调整窗体大小以适应用程序户分辨率。

Public Function CheckRez(pixelWidth As Long, pixelHeight As Long) As Boolean

'

Dim lngTwipsX As Long

Dim lngTwipsY As Long

'

' convert pixels to twips

lngTwipsX = pixelWidth * 15

lngTwipsY = pixelHeight * 15

'

' check against current settings

If lngTwipsX Screen.Width Then

CheckRez = False

Else

If lngTwipsY Screen.Height Then

CheckRez = False

Else

CheckRez = True

End If

End If

'

End Function

Next, run the following code at the start of the program:

If CheckRez(640, 480) = False Then

MsgBox "Incorrect screen size!"

Else

MsgBox "Screen Resolution Matches!"

End If

vb.net中怎么使窗体全屏显示?

Me.Height = My.Computer.Screen.Bounds.Height

Me.Width = My.Computer.Screen.Bounds.Width

这是设置窗体的长宽和屏幕的分辨率一样大小,相当于全屏。

如果Me.WindowState=FormWindowState.Maximized的话,只是单纯的将窗体最大化,但恢复窗口大小后窗体的大小实际上还和原来一样大。

vb.net屏幕分辨率的单位是什么?

默认单位是像素

96是系统的一种设定,每英寸的点数,是系统界面用小字体时的设置

用像素数除以DPI没有意义
