[SNP] Convert Base64 string to BItmap / Image / Picturebox.Image [VB.NET]

Okay, this is the second part of :
[SNP] Convert Image / PictureBox Image / Bitmap to string / text [VB.NET]


Here is a function, that will convert the Base64 string to Bitmap / Image back again.

But first:

Imports System.IO

Then:

 Public Function StringToBitmap(ByVal sImageData As String) As Bitmap
        Try
            Dim ms As New MemoryStream(Convert.FromBase64String(sImageData))
            Dim bmp As Bitmap = Bitmap.FromStream(ms)
            Return bmp
        Catch ex As Exception
            Return Nothing
        End Try
    End Function

Use it like this:

 Dim IMG As Bitmap = StringToBitmap("PUT CONVERTED IMAGE'S STRING HERE")

Or like this:

   PictureBox1.Image = StringToBitmap("PUT CONVERTED IMAGE'S STRING HERE")

Do not forget, that if you put the image's string in a textbox, it may limit the default lenght of the textbox.text.

I am sorry for the long delay, but here we go again !

A code to convert your bitmap/picturebox image to string and another one to reverse it.

But you must: Imports System.IO first ;)

 Public Function BitmapToString(ByVal bImage As Bitmap) As String
        Try
            Dim data As String
            Dim ms As MemoryStream = New MemoryStream
            bImage.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)
            data = Convert.ToBase64String(ms.ToArray())

            Return data
        Catch ex As Exception
            Return String.Empty
        End Try
    End Function

Use it as this:

        Dim STR As String = BitmapToString(BITMAPIMAGE)

Or like this:

  Dim STR As String = BitmapToString(PictureBox1.Image)

The next post will be about a function, to convert it back to image/bitmap

[SNP] Using HTTPWebRequests to login to Facebook [VB.NET]

Dim cookieJar As New Net.CookieContainer()
  Dim request As Net.HttpWebRequest
  Dim response As Net.HttpWebResponse
  Dim strURL As String = ""

  Try
    'Get Cookies
    strURL = "https://login.facebook.com/login.php"
    request = CType(HttpWebRequest.Create(strURL), HttpWebRequest)
    request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3"
    request.Method = "GET"
    request.CookieContainer = cookieJar
    response = CType(request.GetResponse(), HttpWebResponse)

    For Each tempCookie As Net.Cookie In response.Cookies
    cookieJar.Add(tempCookie)
    Next

    'Send the post data now
    request = CType(HttpWebRequest.Create(strURL), HttpWebRequest)
    request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3"
    request.Method = "POST"
    request.AllowAutoRedirect = True
    request.CookieContainer = cookieJar

    Dim writer As StreamWriter = New StreamWriter(request.GetRequestStream())
    writer.Write("email=username&pass=password")
    writer.Close()
    response = CType(request.GetResponse(), HttpWebResponse)

    'Get the data from the page
    Dim stream As StreamReader = New StreamReader(response.GetResponseStream())
    Dim data As String = stream.ReadToEnd()
    response.Close()

    If data.Contains("<title>Facebook") = True Then
    'LOGGED IN SUCCESSFULLY
    MessageBox.Show("logged in sucessfully")
    Else
    MessageBox.Show("Not logged in")
    End If

  Catch ex As Exception
    MessageBox.Show(ex.tostring)
  End Try

With this basic HTTPWebRequest you can check if the login details - user and password are correct .
