Answer / debolina

For Save Images:

Private Sub Save()
Dim strConn, strQuery As String
Dim cmd As SqlCommand
Dim img As Image
Dim imagedata As Byte()
Dim imgFormat As Imaging.ImageFormat
Dim myParameter As SqlParameter
Try
img = Image.FromFile(Me.txtImage.Text)
imgFormat = img.RawFormat

imagedata = ConvertImageToByteArray(img, imgFormat)

strQuery = "Insert into TBL_STUDENT
(STUD_NAME,SUBJECT,NUMBER,IMAGES) values ('" & txtName.Text
& "','" & txtSubject.Text & "'," & txtNumber.Text & ",@Image)"
strConn = //Your Connection String
conn = New SqlConnection(strConn)
cmd = New SqlCommand(strQuery, conn)

myParameter = New SqlParameter("@Image",
SqlDbType.Image, imagedata.Length)
myParameter.Value = imagedata
cmd.Parameters.Add(myParameter)


conn.Open()
cmd.ExecuteNonQuery()

MsgBox("Saved Successfully", MsgBoxStyle.OkOnly)
Catch ex As Exception

End Try
End Sub

Private Shared Function ConvertImageToByteArray(ByVal
imageToConvert As System.Drawing.Image, ByVal formatOfImage
As Imaging.ImageFormat) As Byte()
Dim Ret As Byte()

Try
Using ms As New MemoryStream()
imageToConvert.Save(ms, formatOfImage)
Ret = ms.ToArray()
End Using
Catch generatedExceptionName As Exception
Throw
End Try

Return Ret
End Function

For Retrieve:

Private Sub RetrieveImages()
Dim strConn As String
Dim cmd As SqlCommand
Dim da As SqlDataAdapter

Try
strConn = //Connection string
conn = New SqlConnection(strConn)
cmd = New SqlCommand("Select * from
TBL_STUDENT", conn)
da = New SqlDataAdapter(cmd)
ds = New DataSet
da.Fill(ds)
Catch ex As Exception

End Try
End Sub

How to store jpeg / gif / bmp image in database and how to retrieve them? The most stressful condit..

Answer / raj

Hi Rahul,
if you want to save image in SQL Server DataBase,
first we have to convert that image into bytes(BCoz SQL
Server support byte format).
using system.io.iostream we can convert image into stream
of bytes.

For example :

stfFilename is path that contain your image.

Public Shared Function LoadImage(ByVal stfFilename As
String) As System.Drawing.Image

Dim oStream As System.IO.Stream
Dim oAssembly As System.Reflection.Assembly
oAssembly = System.Reflection.Assembly.GetEntryAssembly
oStream = oAssembly.GetManifestResourceStream(stfFilename)
Return System.Drawing.Image.FromStream(oStream)
End Function

for retrieving image from DB just reverse concept.
