VB.NET打印问题(有滚动条控件的内容怎么全部打印)

参考:

把执行SQL语句后得到的记录集逐条(含字段名)显示在LISTVIEW控件中

'----------------------------------------------------------------

Public Sub ListUpdate(ByRef rs As Recordset, ByRef lv As ListView)

Dim head As ColumnHeader, Item As ListItem

Dim i As Integer, j As Integer

'初始化LISTVIEW的某些属性

lv.View = lvwReport

lv.GridLines = True

lv.FullRowSelect = True

lv.ListItems.Clear

lv.ColumnHeaders.Clear

For i = 0 To rs.Fields.Count - 1

Set head = lv.ColumnHeaders.Add

head.Text = rs.Fields(i).Name

head.Width = lvWidth / rs.Fields.Count

Next

For j = 1 To PERPAGE

If rs.EOF Then Exit For

Set Item = lv.ListItems.Add

Item.Text = "" rs.Fields(0).Value

For i = 1 To rs.Fields.Count - 1

Item.SubItems(i) = "" rs.Fields(i).Value

Next

VB用随机函数产生50个【10-100】的随机整数,并按照从小到大的顺序打印出来

Dim A(50) As Integer

Private Sub Command1_Click()

Randomize

For i = 1 To 50

A(i) = Int(Rnd * 90 + 10)

Next i

Picture1.Cls

Picture1.Print "排序前数据:"

For i = 1 To 50

Picture1.Print A(i);

If i Mod 10 = 0 Then Picture1.Print

Next

End Sub

Private Sub Command2_Click()

For i = 1 To 49

Max = A(i)

For j = i + 1 To 50

If A(j) Max Then

Max = A(j)

temp = A(i): A(i) = A(j): A(j) = temp

End If

Next

Next

Picture1.Print "排序后数据:"

For i = 1 To 50

Picture1.Print A(i);

If i Mod 10 = 0 Then Picture1.Print

Next

VB.net 数组怎么按任意元素的顺序排序输出

你直接传一个数组进去,而且是一个结构体数组,array.sort怎么知道根据结构中的哪一个属性进行排序?放一个c#的代码你看看,VB和C#很相似的

class Program

{

static void Main(string[] args)

{

People[] p = new People[3]

{

new People{name="张三"},

new People{name="李四"},

new People{name="张二名"}

};

//重点传一个实现了IComparer接口的类进去,告诉Array.Sort怎么排序

Array.Sort(p, new PeopleCompare());

foreach (var item in p)

{

Console.WriteLine(item.name);

}

Console.ReadKey();

}

}

//People结构体,换成类一样的

public struct People

{

public string name { get; set; }

}

//实现了IComparer接口的类

public class PeopleCompare : IComparer

{

public int Compare(object x, object y)

{

People p1 = (People)x ;

People p2 = (People)y;

return p1.name.CompareTo(p2.name);

}

}
