vb.net保存圖片時(shí)如何調(diào)整其分辨率

保存前加一句 myImage2.SetResolution(300, 300) 你設(shè)置的bMape不是保存的主畫布 所以無效，設(shè)置分辨率就是 SetResolution（X,Y）

vb.net 怎樣將窗體和所有控件根據(jù)電腦分辨率固定？

使用SplitContainer1控件不就行了，SplitContainer1控件的Fixedpanel屬性設(shè)置為Panel1\x0d\x0aSplitContainer1的Panel2里面再放置一個(gè)SplitContainer2\x0d\x0aSplitContainer2控件的Fixedpanel屬性設(shè)置為Panel2\x0d\x0a二個(gè)SplitContainer設(shè)置為水平折為器方向\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設(shè)置為FILL\x0d\x0a\x0d\x0a這樣不管放大縮小界面，播放器控件總是自適應(yīng)窗體大小而菜單按鈕總是在最邊緣

在VB.NET中通過那個(gè)函數(shù)可以獲取當(dāng)前屏幕的分辨率?

您可以用下面給出這一小段代碼檢測當(dāng)前屏幕分辨率，然后根據(jù)結(jié)果作出反應(yīng)──例如，重新調(diào)整窗體大小以適應(yīng)用程序戶分辨率。

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)調(diào)用API使窗口大小能夠超過屏幕分辨率要怎么做???

首先你要熟悉API函數(shù)，具體用哪些函數(shù)就不記得了~~~~~

其次，把你要用到API函數(shù)引用到代碼中來，就可以用了啊

VB里貌似這段代碼挺多的，需要好好研究

C#中，可以通過

winform窗體分辨率問題解決方案：

你也可以選擇使用TableLayoutPanel等控件作為容器，把其他的控件放入Panel中，這個(gè)控件會使其中包含的控件隨著程序環(huán)境的變化而變化。

注：TableLayoutPanel和Panel控件的DOCK屬性應(yīng)該都設(shè)為：fill。

的方法來實(shí)現(xiàn)~~~~~~~~~~·
