ASP.NET and GDI+

Please,

I need help
What I want is:
Using ASP.NET, VB.NET and GDI+in the same aspx PAGE to be able to display a simple text using a text box, a button and ??? to place to display the text.

Thanks.

Best regards.
:confused:

What do you need GDI for? Just add a button, a textbiox, and a label. Set the label text..That is all.

I don't need a Label because with GDI+ I have infinite posibilities to do with a text .

Best regards.:confused:

but it will be a lot more time consuming

and if many ppl go to ur page it will eat ur ram up all

Is the text custom to every visitor? If it isn't, and is just changed every now and then, you might want to look into having the page create one graphic, store it on the server, and include that in the page. Whenever you want a new graphic created, you can schedule your app to do so, and overwrite the old one.

i think I see what you mean. Look into the Bitmap object. You can create a new Bitmap object, then use the graphics object DrawString to write text to it, and use Bitmap.Save to write it out to the response object. Here is a little mor ecomplex example

Code:

<%@ Page Language="VB" ContentType="image/jpeg" %>
<%@ Import Namespace="System" %>
<%@ Import Namespace="System.Drawing" %>
<%@ Import Namespace="System.Drawing.Drawing2D" %>
<%@ Import Namespace="System.Drawing.Imaging" %>

<script language="VB" runat="server">

Sub Page_Load(Sender as Object, E as EventArgs)
        Dim rnd As New Random()
        Dim strText As String
        ' create a font
        Dim fnt As Font = New Font("Arial", 12, FontStyle.Bold)
        ' Load a bitmap based image from a file
        Dim newBitmap As Bitmap = New Bitmap(Server.MapPath("back.jpg"))
        ' This line is for creating a blank bitmap.
        'Dim newBitmap As Bitmap = New Bitmap(400,50,PixelFormat.Format32bppARGB)
        ' Bind the Bitmap to the graphics object
        Dim g As Graphics = Graphics.FromImage(newBitmap)
       
        ' Get a random number to choose what text to show
        Select Case rnd.Next(5)
                Case 1
                        strText = "The place to be!"
                Case 2
                        strText = "What did you expect this message to say?"
                Case 3
                        strText = "How about a nice hot cup of STFU!"
                Case 4
                        strText = "Proving Monkeys CAN fly!"
                Case Else
                        strText = "D'oh!"
        End Select       
       
        ' get the length of the string in pixels
        Dim tempg As Graphics = Graphics.FromImage(new Bitmap(1,1))
        Dim StringLength As Integer = tempg.MeasureString(strText,fnt).Width
        tempg.Dispose
       
        g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias
        g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias
       
        ' Draw the string to the Graphics object. Subtract the strings pixel length from the
        ' images width do determine postioning so that the lst character is always along the
        ' right edge of the image. Draw shadow first
        g.DrawString(strText, fnt, New SolidBrush(Color.Black), newBitmap.Width - StringLength, 65)
        g.DrawString(strText, fnt, New SolidBrush(Color.LightSteelBlue), newBitmap.Width - StringLength - 2, 63)
       
        ' Get an array of ImageEncoders..array item 1 is Jpeg.
        Dim imgCodecs() As ImageCodecInfo  = ImageCodecInfo.GetImageEncoders()
       
        ' Set quality Parameter for the Jpeg codec
        Dim imgParams As EncoderParameters = New EncoderParameters(1)
        Dim imgQuality As EncoderParameter = New EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 80)
        ' Set quality
        imgParams.Param(0) = imgQuality
       
        ' Render BitMap Stream Back To Client
        newBitmap.Save(Response.OutputStream,imgCodecs(1), imgParams)
        fnt.Dispose()
        g.Dispose()
End Sub
