hi , I am pradeep.
i wrote a code to get all information with in brackets of each sin() ,which i would like to give as my input to text box.
but i am not able to get it exactly,
for example i write "sin(90*2)+sin(60)+sin(60+(75*2))+sin(50)+sin(20)" in textbox
i need "90*2,60,60+(75*2),50,20" as my out put
here is my code what i wrote ,please modify my code and help me
public class form1
Private Sub Button25_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button25.Click
Dim j As Integer = 0
Dim startPos As Integer
Dim parenCount As Integer = 1
Dim innerLen As Integer = 0
For j = 0 To TextBox1.Text.Length - 1
startPos = TextBox1.Text.IndexOf("sin(", j) + 4
For i As Integer = startPos To TextBox1.Text.Length
If TextBox1.Text(i) = "("c Then
parenCount = parenCount + 1
End If
If TextBox1.Text(i) = ")"c Then
parenCount = parenCount - 1
End If
If parenCount = 0 Then
Exit For
End If
innerLen = innerLen + 1
Next i
MsgBox(TextBox1.Text.Substring(startPos, innerLen))
Next j
End Sub
end class
