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~~~~~

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
