Trying to run my app. in VS 2005 and keep getting this error message:
"This application is currently offline. To enable the application, remove the app_offline.htm file from the application root directory"

Anyone any ideas how to solve this problem or what it is.

I cannot find app_offline.htm.

there is one main reason for this error which i have faced

when your IIS Server is down VS.Net2005 Framework would automatically add a file called app_offline.htm

Remove this file and then restart your IIS and then try.
there might be some other error which would be coming but since IIS is down and framework doesnot get any response. it adds the page app_offline.htm and start showing instead of the actual error.

Hi all,
How can we change the value of a BoundField of Gridview like I have password field in table user_Information and I am storing password in encrypted form. My problem is that when I use following format, the Password field show those password in Encrypted form(i.e. stored in table) but I want to show them in decrypted form. I don't know whether it is possible or not, if yes please let me know. I am using AccessDatasource object to bind the GridView.
Thanks in advance.....

I'm not sure that I understood correctly, but I suggest using the DataRowBound event of the GridView and replace the values you want.

I would convert the boundfield for the password to a template field. something like this:

<asp:TemplateField SortExpression="User_Password">
<ItemTemplate>
<asp:Label ID="lbPassword" runat="server" Text='<%# DecryptPassword(DataBinder.Eval(Container.DataItem,"User_Password")) %>'></asp:Label>

Then make sure your method to DecryptPassword is public so the DataBind can call it.

I haven't actually tried to do this, but I think the code above will work.

Hope that helps.

Don't cross post, but to answer your question, I believe you will need to write your own thumbnail generator.

Luckly for you, here's one I already done :-

Create a new Web Form and call it Thumbnail.aspx
Put the following code in the code behind

Partial Class Thumbnail<br />
    Inherits System.Web.UI.Page<br />
<br />
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load<br />
        Try<br />
            Dim oImage As System.Drawing.Image<br />
            Dim oThumbnail As System.Drawing.Image<br />
            Dim sServerPath As String<br />
            Dim sFileName As String<br />
            Dim iWidth As Int16<br />
            Dim iHeight As Int16<br />
<br />
            sServerPath = AppPath() & Request.QueryString("p")<br />
            sFileName = Request.QueryString("f")<br />
            Try<br />
                oImage = System.Drawing.Image.FromFile(sFileName)<br />
            Catch ex As Exception<br />
                oImage = System.Drawing.Image.FromFile(AppPath() & "Images\error.gif")<br />
            End Try<br />
<br />
            If Request.QueryString("w") = Nothing And Request.QueryString("h") Is Nothing Then<br />
                iWidth = oImage.Width<br />
                iHeight = oImage.Height<br />
            ElseIf Not Request.QueryString("w") Is Nothing And Not Request.QueryString("h") Is Nothing Then<br />
                iWidth = Request.QueryString("w")<br />
                iHeight = Request.QueryString("h")<br />
            ElseIf Not Request.QueryString("w") Is Nothing Then<br />
                iWidth = Request.QueryString("w")<br />
                iHeight = oImage.Height / (oImage.Width / iWidth)<br />
            ElseIf Not Request.QueryString("h") Is Nothing Then<br />
                iWidth = oImage.Width / (oImage.Height / iHeight)<br />
            End If<br />
<br />
            oThumbnail = oImage.GetThumbnailImage(iWidth, iHeight, Nothing, System.IntPtr.Zero)<br />
            Response.ContentType = "image/jpeg"<br />
            oThumbnail.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg)<br />
            oImage.Dispose()<br />
            oThumbnail.Dispose()<br />
        Catch ex As System.Exception<br />
            'Your error handling here<br />
        End Try<br />
    End Sub<br />
End Class

To use the Thumbnail.aspx simply call into from the webpage you wish the thumbnail to appear like so :-

<img src="Thumbnail.aspx?w=100&f=myimage.jpg">

The w parameter represents the width of the thumbnail, you call also use a h parameter for the height or combine the two. The f parameter is path to the image.

Dear kiran,

you have to read the content of the file and then store the content in sql server and have to maintain the file name and extensions.

When you need to get the file back means you can create the file through the

content then you can send it to the client using response.writefile method

All The Best

I tried to setup a web server using IIS 5.1 on my Windows XP but somehow, it's only working on that PC. I know that I should not be using XP as a server on our company but since I will use it only for small transactions, i'd rather give it a try. I installed the old version of Apache 2.0.54 plus modules and it works perfectly... is there any advise from any experts here??? shall i stick to Apache or try IIS + Prayers to make it work?

Do you know Windows XP is built in with a Personal Firewall? Windows Firewall restrict port 80 to be access by the outsiders by default. You have to add a exception to port 80 in the Windows Firewall and try to access from other machines.

Another drawback of using Windows XP as Server is, XP can serve for maximum of 10 connections only. As a result, your Webpage will not open fully (Images may not load) or restricts some connections. Have a nice day... :->

Thanks Venkatesh for the info. I already added the port 80 to windows firewall but still failed. Regarding the limitations of XP, maybe i need to change my OS to maximize the connection. But is it advisable to use IIS or Apache? what do you think is the best for ASP.NET?

Actually you could and it's very easy! but you will have some difficulties in finding the right version of Apache which is (2.0.54). I think this is the only version that have the modules for ASP.NET. you need to install mod_aspdotnet 2.0.0 then a little bit configuring. but let's stick to IIS.. Big Grin | :-D

Is there any free domain that host ASP.NET?
