求解怎样在vB中求出有字的行数

借助另存为txt. ActiveWorkbook.SaveAs Filename:="D:\Users\soulbag\Desktop\新建文本文档2.txt", FileFormat:=xlUnicodeText, CreateBackup:=False 然后用 vb的读文件 readline 遍历 txt的 用split 分割每一行vbtab.成数组 看 arr(0) 是否为空...

'获得光标位置(按字节计算,起如行和起始列均为0) Private Function GetCurPos(ptPos As POINTAPI) As Long Dim nLine As Long, nCol As Long Call SendMessage(Me.Text1.hwnd, EM_GETSEL, 0, ptPos) nLine = SendMessage(Me.Text1.hwnd, EM_L...

先在窗体上放置一个 Label1,右键点它,点复制。然后在窗体空白处按右键,点粘贴,提示会问是否创建控件组。点是,控件组就做好了。然后把粘贴出来的Label1(1)删掉,只留下Label1(0),并把它放在靠左上合适的位置。然后代码如下: Private Sub F...

Dim rng As Range Dim i As Integer, j As Integer Set rng = xl.ActiveSheet.UsedRange i = rng.Rows.Count '已使用的行数 j = rng.Columns.Count'已使用的列数 但是建议你不使用这种方式,比如你的excel有3行,然后你在第5行里写入数据,然后...

Module Module1 Sub Main() Dim i, j, k As Integer For j = 2 To 1000 k = 0 For i = 1 To j / 2 If j Mod i = 0 Then k = k + i End If Next If j = k Then Console.WriteLine("完全数为" & k) End If Next Console.ReadLine() End SubEnd Module

Dim a() As Integer, n As IntegerPrivate Sub Command1_Click() ReDim a(1 To n) Randomize (Timer) For i = 1 To n a(i) = Int(Rnd(i) * 900 + 100) Next i Call median(a, n)End SubPrivate Sub Command2_Click() ReDim a(1 To n) For i = 1 ...

Dim x As IntegerPrivate Sub Command1_Click()x = 1MsgBox CalcStr(Replace(Text1.Text, "x", x))End SubFunction CalcStr(strNum As String) As DoubleDim MSSC As ObjectSet MSSC = CreateObject("MSScriptControl.ScriptControl")MSSC.Langu...

VB中Log(N) 表示以e为底的自然对数即LnN 要计算以n为底x的对数值,可以借助于数学上的换底公式,写为Log(x)/Log(n)。

编写一个判断素数的函数: function prime(x as long) as boolean dim i as long for i=2 to x-1 if x mod i=0 then prime=false exit function end if next i prime=trueend function主程序循环2~50,依次调用上面的函数prime判断是否素数,代...

非常简单, 在窗体上建立两个text 和一个command ,复制下面的代码 就搞定 Private Sub Command1_Click() Dim str() As String, zf As String zf = InputBox("请输入要查询的字符") str = Split(Text1.Text, zf) Text2.Text = zf & "出现的次数是"...
