Dim fs As FileStream
Try
fs = New FileStream("C:\Inetpub\wwwroot\xyz.jpg", FileMode.OpenOrCreate, FileAccess.Write)
Dim l As Long
l = UBound(bytes)
fs.Write(bytes, 0, l)
Catch ex As Exception
Finally
fs.Close()
End Try
here bytes is a byte array which holds the binary data from the databse
after that assign the file name to ur image control.

I don't think you can directly render a raw file as an image in HTML. You are going to need to transform that .RAW file into a .jpg or something else that is readable by a web browser. I would look into possible using the SDK provided by Canon or maybe Nikon. Beyond that, and not knowing anything about the RAW file (each RAW format is different, it isn't standarized from my understanding)

Normally when storing images in databases blobs are used. Simply load data in memory stream and then create bitmap object from that stream, save a temp image and built a URL to that new temp image and then anchor it on desired location.

Question about tag : <form> and runat="server".</form>

Hello.

I made a master page whose name is "main.master".

and I used this tag :

And..

I made a sub page which is connected with the master page.

I alreay know I shouldn't use the tag; like this.

So, I made coding like the following this below.

<form>
<div align="center">
<hr/>
</div>

<p>Sample textarea follows:</p>

<textarea id="yourFieldNameHere" style="width:814px; height:95px" runat="server">

</textarea><br/>
<script type ="text/javascript" language="JavaScript1.2">
editor_generate('yourFieldNameHere');

</script>

In the area of , unless I use runat="server", it won't work.

It won't show the Text Editor. (I'm making Text Editor though.^^)

In addition, if I make this way :<script type ="text/javascript" language="JavaScript1.2" runat="server">, then, there is a message "JavaScript1.2 is not a language applied for ASP.NET".
But, no matter how I change "language = "JavaScript" runat="server", it still doesn't work.

Any helps??

Thank you..

I dont Think U have to Use tag again i.e. the masterpage has a form tag

But If u want to use the Script tag
then use it in Content place holder Like Below

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

    <script type="text/javascript">
    function checkDate(sender, args) {
        if (sender._selectedDate > new Date()) {
            alert("You cannot select a day greater than today!");
            sender._selectedDate = new Date();
            // set the date back to the current date
            sender._textbox.set_Value(sender._selectedDate.format(sender._format))
        }
    }
      </script>

Why would you use outlook to send mail in a web app ?

In any case, this is the ASP.NET forum, asp has been obsolete for a long time. The web dev forum is still there for people using antiquated technologies.

There is no separate place for asp. Thats why i put my query here.

My client does not give user name & password to authenticate mails. With out authentication they dont want send mail. So CDO is not a right choice in this place, thats why i choose outlook. I can ask them to configure outlook in webserver then i can send mails through this.

I can't make head or tails of this. Did you fail to mark your post to not parse HTML tags, and actually post a web.config file ?

It's usually wise to tell us what the error message is, instead of asking us to guess.

sashidhar, This is correct !
But I guess, this code is applicable for CS file not in web.config. This is not good to provided hardcoded ConnectionString in Code. Smile | :)

   <add key="dbfile" value="~/App_Data/data.mdb"/>
 </appSettings>
