vs2008中创建的的VB.net项目如何分模块设计
你这个问题不怎么号回答,实际上一个项目可以分成N个小项目,具体如何划分需要根据经验以及具体情况具体分析,这方面有专门的书籍来论述,不是一两句能讲清楚。这里只是讲一下划,下图,rocket项目划分为bootcode rbuild......等5个子项目,每个子项目可以完成自己功能 ,总项目调用这些子项目的功能。

期末老师让做一个比较有创意的vb.net小软件,无从下手!求帮忙
随手做了个打地鼠,代码拿去吧。
下图是10x10超大窗体“打地鼠”
直接新建个窗体,覆盖全部代码,不需要拖控件,全部动态创建了。
参数都在前面几行,可以随便改。
格子宽和高是70,间距20,因此横格子和竖格子不要超过10,不然窗体会扩张到非常大的程度。
调整时钟的Interval可决定地鼠的出现频率,你可以修改变化概率 = 15这句话改变出现几率。

求写一个VB.Net小程序
随机生成2-5阶方阵:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim d(,) As Integer
Dim n As Integer
Dim i As Integer
Dim j As Integer
Randomize()
n = Int(4 * Rnd() + 2)
ReDim d(n, n)
Label1.Text = ""
For i = 1 To n
For j = 1 To n
d(i, j) = Int(Rnd() + 0.5)
Label1.Text = Label1.Text d(i, j) " "
Next
Label1.Text = Label1.Text vbCrLf
Next
End Sub
谁能帮我用VB.net做个简单的游戏设计啊,我快愁死了
这是个vb6的BINGO小游戏的代码 如果要源程序 去我资料里找我网盘的地址 下载bingo.rar
因为没有任何第三方控件,可以直接转成vb.net的!~

vb.net 如何在一个项目中创建类,并且使用他?
在任意form类或模块中都可以创建类,跟建立函数和过程一样。
示例:
public class form1
‘创建一个属于form的子类,名称为【类名】。
public class 类名
’定义类成员text
public text as string
end class
‘定义一个【类名】类的公共变量。
dim 类名1 as 类名
’定义一个过程,使用【类名】类的text成员
public sub 过程
‘实例化【类名1】
类名1=new 类名
类名1.text=“赋值”
’定义一个【新类】类的私用变量,并实例化。
dim 新类1 as new 新类
新类1.name=“一个字符串”
新类1.age=12
end sub
end class
‘’‘创建一个与form同级的类,名称为【新类】
public class 新类
public sub new()
end sub
public name as string
public age as integer
end class
在模块中使用:
public class module1
dim a as new form1.类名
end module
