How To Validate Textbox : Only Numbers, Only Characters, Not Null, Only Email in VB.NET , textbox

Today I have brought you something delicious :) so you guys wonder how it works , first we have to create a module and we just have to assign the textbox for a validation (Only Number,Only Characters,Not Null,Only Email) so first of all lets create a new module and add this codes

Imports System.Text.RegularExpressions
Module Module1
    Public Enum ValidationType
        Only_Numbers = 1
        Only_Characters = 2
        Not_Null = 3
        Only_Email = 4
    End Enum
    Public Sub AssignValidation(ByRef CTRL As Windows.Forms.TextBox, ByVal Validation_Type As ValidationType)
        Dim txt As Windows.Forms.TextBox = CTRL
        Select Case Validation_Type
            Case ValidationType.Only_Numbers
                AddHandler txt.KeyPress, AddressOf number_Leave
            Case ValidationType.Only_Characters
                AddHandler txt.KeyPress, AddressOf OCHAR_Leave
            Case ValidationType.Not_Null
                AddHandler txt.Leave, AddressOf NotNull_Leave
            Case ValidationType.Only_Email
                AddHandler txt.Leave, AddressOf Email_Leave
        End Select
    End Sub
    Public Sub number_Leave(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
        Dim numbers As Windows.Forms.TextBox = sender
        If InStr("1234567890.", e.KeyChar) = 0 And Asc(e.KeyChar) <> 8 Or (e.KeyChar = "." And InStr(numbers.Text, ".") > 0) Then
            e.KeyChar = Chr(0)
            e.Handled = True
        End If
    End Sub
    Public Sub OCHAR_Leave(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
        If InStr("1234567890!@#$%^&*()_+=-", e.KeyChar) > 0 Then
            e.KeyChar = Chr(0)
            e.Handled = True
        End If
    End Sub
    Public Sub NotNull_Leave(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim No As Windows.Forms.TextBox = sender
        If No.Text.Trim = "" Then
            MsgBox("This field Must be filled!")
        End If
    End Sub
    Public Sub Email_Leave(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim Email As Windows.Forms.TextBox = sender
        If Email.Text <> "" Then
            Dim rex As Match = Regex.Match(Trim(Email.Text), "^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,3})$", RegexOptions.IgnoreCase)
            If rex.Success = False Then
                MessageBox.Show("Please Enter a valid Email Address", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information)
                Email.BackColor = Color.Red
                Exit Sub
                Email.BackColor = Color.White
            End If
        End If
    End Sub
End Module

now lets test the module i mean lets add 4 textboxes and assign each for a validation and see whether it works !

add 4 textboxes  now add labels for each like this

validate textbox in

you can only enter numbers in textbox1
you can only enter characters in textbox2
you cannot leave textbox3 blank
you can only enter email in textbox4

now go to form_load event and add these codes


        AssignValidation(Me.TextBox1, ValidationType.Only_Numbers)
        AssignValidation(Me.TextBox2, ValidationType.Only_Characters)
        AssignValidation(Me.TextBox3, ValidationType.Not_Null)
        AssignValidation(Me.TextBox4, ValidationType.Only_Email)

thats where we assign the textbox for a validation !!

now lets test it just debug and try entering characters in textbox1 you cannot enter , go to textbox2 try entering characters you cannot enter , go to textbox3 and without entering anything go to textbox4 a message box will popup now go to textbox4 and enter something and click into another textbox and he textbox4 will be red in color and you will get a message

thanks for reading hope this is useful ! share ! comment !

How To Make God Mode Windows 7 In C#/VB.NET

god mode is just a folder that can be used to control anything it's really easy rather than using the windows control panel because it has all the things that a user can control :) now we are going to create that folder using c# . just put these codes in button click event or form_load event

string godmode = @"D:\god.{ED7BA470-8E54-465E-825C-99712043E01C}";

you need to add the using; namespace to make the directory applicable . now you see when i debug the program and make the event work there will be a folder called god.{ED7BA470-8E54-465E-825C-99712043E01C} remember god is the folder name and this is the extension {ED7BA470-8E54-465E-825C-99712043E01C}

if you want to do it in use this codes

        Dim godmode As String = "D:\god.{ED7BA470-8E54-465E-825C-99712043E01C}"

you need to add the namespace imports

now when you debug i mean when i debug i will show you the folder created in my D drive

as you see you will also see the same folder created in the directory you have given ok now i will show inside of the god folder

you have 274 files inside : how cool

i hope you enjoy this tutorial very much .

How To Make Scrolling Graphics Effect In VB.NET

    Dim g As Graphics = Me.CreateGraphics
    Dim offsetvalue As Integer = 150
    Dim x, y, cx, cy As Integer
    Dim randd As New Random

        rota = 10
        x = randd.Next(0, Me.Width)
        y = randd.Next(0, Me.Height)
        cx = randd.Next(5, 10)
        cy = randd.Next(5, 10)

        End If
        Dim G_path As GraphicsPath = New GraphicsPath()
        Dim rectangle As RectangleF = New RectangleF(x, y, 200, 100)
        Dim str_format As StringFormat = New StringFormat()
        str_format.Alignment = StringAlignment.Center
        str_format.LineAlignment = StringAlignment.Center
        G_path.AddString("Ultimate programming tutorials", Me.Font.FontFamily, CInt(Me.Font.Style), Me.Font.Height + 15, rectangle, str_format)
        angle += rota
        If angle > 360 Then
            rota = -rota

        ElseIf angle < 0 Then
            rota = -rota
        End If
        g.DrawPath(New Pen(Brushes.Black, 4), G_path)
        g.FillPath(Brushes.Azure, G_path)
        Dim matrix As Matrix = New Matrix()
        matrix.Translate(0, 0)
        matrix.RotateAt(angle, New PointF(Me.Width / 2 + (50), Me.Height / 2 - (50 / 2)))
        g.DrawPath(New Pen(Brushes.White, 4), G_path)
        g.FillPath(Brushes.Black, G_path)
        g.DrawPath(Pens.Black, G_path)
    End Sub
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    End Sub
End Class

don't do anything for the timer . just tweak the codes for your need and enjoy .
