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）

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
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

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~~~~~~~~~~·
