Try this:

messageArea.Attributes.Add("style", "display:block")

There is a typo of extra ">" inside;

runat="server">style='display:none;'

Hello Peter

Many thanks for that. Those errors have gone now.

Previously, if I clicked on the upload button without selected any file, I got this message:

"Your file " & Convert.ToString(uploadControl.PostedFile.FileName) & " can not be uploaded.<br>File types allowed: .doc, .docx, .txt, .png, .gif, .bmp, .jpg, or .jpeg.<br>"

Now, I don't get any message on screen. Likewise, if I select an .asp file which is not, strictly speaking, allowed, no message appears either.

I just wonder if the CSS and/or ASP label:

<<pre>asp:label id="messageArea" CssClass="formattedText" runat="server" style='display:none;'></asp:Label

is preventing the message(s) from appearing?

Thanks again.

I can only say that

style='display:none;'

will cause the "messageArea" label not to be shown.

I have removed that and I can now see the relevant text when I deliberately commit an error (wrong file type or no file). A step forward, thanks!

The only remaining problem is that when I remove

style='display:none;'

and before I attempt to upload anything, I can see on the screen a small white empty box with nothing in it. That box should really only appear with the error text when I have committed an error.

It should be this, but I haven't used it on a web form in a while
So I always remove the pervious style first, then add the style change, so I don't just add the same style back, resulting in 2 of the same styles.

With messageArea
.style.remove(HtmlTextWriterStyle.display)
.style.add(HtmlTextWriterStyle.display, "block")
End With

It is still there that box:

[^]

I have removed what I had in my aspx.vb file, namely:

'messageArea.Attributes.Add("style", "display:block")

and inserted your With | End With here:

Protected AllowedExtensions As String() = {".doc", ".docx", ".txt", ".png", ".gif", ".bmp", ".jpg", ".jpeg"}

    Private Property Label As Object

    Protected Sub uploadButton_Click(sender As [Object], e As EventArgs)

        With messageArea
            .Style.Remove(HtmlTextWriterStyle.Display)
            .Style.Add(HtmlTextWriterStyle.Display, "block")
        End With

        Me.messageArea.Text = String.Empty

        Try

I don't get any debug errors and I have had a look at a couple of Web examples:

http://msdn.microsoft.com/en-us/library/wc500chb.aspx[^]

so I am not sure why your script isn't working.

I looked at your message label in a post above, it looks correct to me.

To make the Label appear, it's display: inline-block;
and to make it not appear, it's display: none;

<asp:label runat="server" id="messageArea" CssClass="iForget" style="display: none"></asp:label>

You might just want to keep the label visible and just put something like
"Ready to upload image file" in it, and just change the text value.

'messageArea.Attributes.Add("style", "display:block")

You can do it that way, but you should really use the HtmlTextWriterStyle for that instead, then you can work with multiple styles.

FYI:

The code we are working with will override the CSS style.

This seems to have done the trick!

<asp:label runat="server" id="messageArea" CssClass="iForget" style='display: none'></asp:label

Just inverted commas here:

style='display: none'

not quotation marks.

I have the aspx file open and select 'View in browser'. The empty box has gone. I click on the browse button, choose an asp file which is not allowed, and I get a warning (white font in the white box) that only certain files are allowed.

This is the CSS:

.iForget {
      display: inline-block;
      display: none;
       font: normal 14px 'Droid Sans' , 'Trebuchet MS' , Arial, sans-serif;
          color: #ffffff;
          position: absolute;
          top: 330px;
          border: 1px solid white;
          padding: 15px;
  }

However, if I then press F5 to refresh/retry the page, that previous error is still there. But I think you have cracked it!

Thanks!

I don't feel comfortable with that, it should be double quote marks.

The iForget was just a placeholder, I wasn't able to remember the name of the CSS class, perhaps you have 2 CSS classes with the same name? Anyways complete your testing using the same name and then change it later, back to something more elegent.

Cleanup the .iForget CSS Class, and just put 1 display statement in it for display: none;

.iForget {
   display: none;
   font: normal 14px 'Droid Sans' , 'Trebuchet MS' , Arial, sans-serif;
   color: #ffffff;
   position: absolute;
   top: 330px;
   border: 1px solid white;
   padding: 15px;
}

In you button code, it should be

Protected Sub uploadButton_Click(sender As [Object], e As EventArgs)
  
  If Page.IsPostback then

   With messageArea //To Show the Message use 'inline-block'
     .style.remove(HtmlTextWriterStyle.display)
     .style.add(HtmlTextWriterStyle.display, "inline-block")
   End With

  End If

End Sub

but remember that the label or span tag will not change until the page posts back to the server and makes the round trip. So I'm not sure what the button click does, if it uploads a file, then the label will not change until the file upload is complete.

So this setup here will make the label not appear. You click the button, the tasks will complete, and then the label will appear.

Yes, thanks.

After changing the code, I previewed it in the browser and uploaded a .txt file and the message '

Successful Upload!

in a white box appeared. Then I uploaded an .asp file and got the expected

<pre>'....cannot be uploaded.<br>File types allowed: .doc, .docx,...

Well, that's exactly what I wanted! No empty white box at the beginning and the script seems to work. As with last time, if I press F5, the previous error is still there. Probably not a lot I can do about that.

Thanks for all your time and great help!

So you want to fix the '....cannot be uploaded.
File types allowed: .doc, .docx,... error ?

I prefer to show that error to give users an idea of what files are allowed and what are not allowed, otherwise they may not understand why their files are not being uploaded.

display contents of GAC 3.5 and 4.5 versions

Thanks again!

I've a web tool that currently output the contents of the GAC to a user. The Tool is built with .Net 3.5 the majority of the servers have .Net 3.5 framework installed. But some servers have been updated with .Net 4.5 framework and now the users want to view the contents of this GAC which is in a different location to 3.5 from C:\Windows\assembly to C:\Windows\Microsoft.NET\assembly. At present the class used to decipher the GAC contents is based on Microsoft KB Article KB317540. This is 3.5 specific. How can I update my app to display the 4.5 GAC contents where applicable?

Does Microsoft plan to continue with WCF:

I know that WCF Web API is now ASP.NET Web API!

WCF still have a future. If we are creating restful services ASP.NET web api is best choice. If we want to develop soap service we should use WCF

ASP.NET WebAPI is used to build Restful HTTP services, whereas WCF is used for building enterprise SOA applications. They have their similarities but are fundamentally different beasts.

They solve different problems, so I would say that certainly for the time being, WCF has a future.
