vb.net分辨率问题,vb分辨率适配

vb.net保存图片时如何调整其分辨率

保存前加一句 myImage2.SetResolution(300, 300) 你设置的bMape不是保存的主画布 所以无效，设置分辨率就是 SetResolution（X,Y）

vb.net 怎样将窗体和所有控件根据电脑分辨率固定？

使用SplitContainer1控件不就行了，SplitContainer1控件的Fixedpanel属性设置为Panel1\x0d\x0aSplitContainer1的Panel2里面再放置一个SplitContainer2\x0d\x0aSplitContainer2控件的Fixedpanel属性设置为Panel2\x0d\x0a二个SplitContainer设置为水平折为器方向\x0d\x0a至于播放器控件就放在SplitContainer2控件Panel1里面\x0d\x0a播放器控件DOCK设置为FILL\x0d\x0a\x0d\x0a这样不管放大缩小界面，播放器控件总是自适应窗体大小而菜单按钮总是在最边缘

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

.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~~~~~~~~~~·
