在VB 语句中 x = Val(Text1.Text) Val Dim y As IntegerPrivate Sub Command1_Click()Text2.Text = yEnd SubPrivate Sub Text1_Change()x = Val(Text1.Text)If x < 0 Or x > 100 ThenText1.Text = Text1.SetFocusLabel1.Caption = 请重新输入ElseLabel1.Ca 在VB中 a=”zpg96daq”,则 Val (a) 为什么 val()+val() 和 str(val()+val()) 的结果相同VB中 val()+val() 为数值 而 str(val()+val())为文本 别人说text只能显示文本 可我发现数值也能显示 VB中Val是什么 VB中求正弦,txtResult.Text = Sin(Val(txtInput.Text * 3.14159 / 180))txtResult.Text是输出值txtInput.Text是输入值为什么得出的结果总是错误的? 【VB的使用中间量交换两个变量数值】Dim x,y As Singlex = Val(Text1.Text)y = Val(Text2.Text)a=xx=yy=a那里错了,交换不成功,可是输入的是整数啊 ,而且交换不了. Private Sub Command_1Click()a=Val(Text1.Text)a=(3.141516180)*ax=Sin(a)x=Int(x*1000+0.5)/1000y=Cos(a)y=Int(y*1000+0.5)/1000Text2.Text=Str(x)Text3.Text=Str(y)End Sub①找出程序中哪些语句是完成信息的输入?哪些语句是完成信息的 VB编程,一元二次方程a*x^2+b*x+c=0的根Dim a As Double Dim b As Double Dim c As Double Dim delta As Double Dim x1 As Double Dim x2 As Double a = Val(Text1.Text) b = Val(Text2.Text) c = Val(Text3.Text) delta = b * b - 在vb中编辑程序,输入一个整数,判断是0,正整数,还是负整数Dim a As Stringa = Val(Text1.Text)If a < 0 Thenb = 负整数ElseIf a > 0 Thenb = 正整数Elseb = 0End IfText2.Text = b我这样有什么问题吗? 用VB子过程,算sin(x),为啥总是不对啊啊T TPrivate Sub Command1_Click()Picture1.ClsDim n As Integer, x As Singlen = Val(Text1.Text)x = Val(Text2.Text)Picture1.Print mysin(n, x)End SubPrivate Function mysin(ByVal n%, ByVal x!) As DoubleDim d 在vb语言中val代表啥意思,懂VB的高手请进. 请问在vb中 输出语句Print j & x & i & = & i * j VB中VAL(-2)的值是多少? 下列代码中为什么要写成 a=Val(Text1.Text),而不是直接写成 a=Text1.Text 如何用vb设计计算二次方程的根的程序Private Sub Command1_Click()Dim a As Single,b As Single,c As Single,d As Singlea = Val(Text1.Text)b = Val(Text2.Text)c = Val(Text3.Text)d = b ^ 2 - 4 * a * cIf d > 0 ThenLabel8.Caption = (-b + Sqr(d)) vb解二次函数代码问题!代码如下Private Sub Command1_Click()Dim a As Single,b As Single,c As SingleDim n As Single,m As Singlea = Val(Text1.Text)b = Val(Text2.Text)c = Val(Text3.Text)If b ^ 2 - 4 * a * c < 0 ThenLabel3.Caption = 无解Els 在vb 中,设变量A的值为-2,则Val(A)的结果是什么, VB奇数求和Private Sub Command1_Click()vl = Val(Text1.Text)vj = Val(Text2.Text)If vl < vj Then Exit SubFor i = 1 To vl Step 2sumi = sumi + iIf sumi >= vj ThenExit ForEnd IfNext iText3.Text = iText4.Text = sumiEnd SubPrivate Sub Form_Load()Me.Capti
