vb.net 中如何處理輸入小寫變大寫
可以試著用典型的VB字符串函數(shù)UCase解決。

比如先把輸入的內(nèi)容放到字符串A$中，若A$="a",則經(jīng)
A$=UCase(A$)轉(zhuǎn)換后，結(jié)果即是A$="A"。
我在程序中是這麼處理的。行不行，試試就知道了。
6.隨機產(chǎn)生一個大寫字母的VB.NET的表達(dá)式是_______(Int(Rnd()*26)+65)。
Chr
用這個函數(shù)，將數(shù)值轉(zhuǎn)換為字符。
生成的隨機數(shù)是在大寫字母A與Z之間的asc碼值，用CHR函數(shù)轉(zhuǎn)為相應(yīng)字符。
怎么用VB.NET 編寫大小寫轉(zhuǎn)化程序
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress e.KeyChar 使用參數(shù)e來控制輸入字符 End Sub 追問： 能給出大小寫切換程序的整段 源代碼 嗎 回答： 我不明白你的大小寫切換程序是要實現(xiàn)什么功能 是輸入 大寫 變小寫嗎？ 追問： 是的 回答： If e.KeyChar.IsLower(e.KeyChar) = True Then e.KeyChar.ToUpper(e.KeyChar) 或 If e.KeyChar.IsUpper(e.KeyChar) = True Then e.KeyChar.ToLower(e.KeyChar)
用VB.NET實現(xiàn)人民幣大小寫轉(zhuǎn)換工具 （互相轉(zhuǎn)換）
Public Function je(ByVal szje As Double) As String
Dim s As String = ""
Dim sz() As String = {"零", "壹", "貳", "叁", "肆", "伍", "陸", "柒", "捌", "玖"}
Dim dw() As String = {"圓", "拾", "佰", "千", "萬", "拾", "佰", "仟", "拾", "佰", "仟"}
If szje 0 Then
s = "負(fù)"
szje = Math.Abs(szje)
End If
Dim zh() As String = Split(Str(szje), ".")
If zh.Length 2 Then
Return "ERROR:格式錯"
Exit Function
End If
zh(0) = Trim(zh(0))
zh(1) = Trim(zh(1))
Dim i As Integer
For i = 1 To Len(zh(0))
s = s sz(Val(Mid(zh(0), i, 1))) dw(Len(zh(0)) - i)
Next
For i = 1 To Len(zh(1))
s = s sz(Val(Mid(zh(1), i, 1))) Choose(i, "角", "分", "厘", "毫")
Next
s = s "整"
Return s
End Function
