<%@ Page Language="VB" AutoEventWireup="false" ContentType="image/gif" %>

<%@ Import Namespace="System.Drawing" %>

<%@ Import Namespace="System.Drawing.Imaging" %>

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

Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

Response.ContentType = "image/gif"

Dim copy As Bitmap = New Bitmap(100, 100)

Dim g As Graphics = Graphics.FromImage(copy)

Dim f As Font = New Font("Tahoma", 11, FontStyle.Bold)

g.DrawString("Test", f, New SolidBrush(Color.Green), 0, 0)

copy.Save(Response.OutputStream, ImageFormat.Gif)

g.Dispose()

copy.Dispose()

End Sub

</script>

 

this file is called genimage.aspx. i want to have this file display a dynamicly generated image in another page. at the other page, it will look something like this:

<asp:Image ID="Image1" runat="server" ImageUrl="barcode.aspx" />

But it seems that genimage.aspx doesn't want to work. Can anybody help me with this??

Thanks,

Alan,

ImageUrl property should be genimage.aspx not barcode.aspx?

also try adding
Response.StatusCode = 200;
Response.End();
after disposing the objects

Hi,

thanks for replying. I still can't get it to work. Here is the most current modified code:

genimage.aspx:

<%@ Page Language="VB" AutoEventWireup="false" ContentType="image/gif" %>

<%@ Import Namespace="System.Drawing" %>

<%@ Import Namespace="System.Drawing.Imaging" %>

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

Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

Response.ContentType = "image/gif"

Dim copy As Bitmap = New Bitmap(100, 100)

Dim g As Graphics = Graphics.FromImage(copy)

Dim f As Font = New Font("Tahoma", 11, FontStyle.Bold)

g.DrawString("Test", f, New SolidBrush(Color.Green), 0, 0)

copy.Save(Response.OutputStream, ImageFormat.Gif)

g.Dispose()

copy.Dispose()

Response.StatusCode = 200

Response.End()

End Sub

</script>

and i made the change to the page calling genimage.aspx also, still doesn't work... i did look at references and I do have system.drawing... 

 

Thanks,
