Hi all,

I've got a little problem. How do I bind a repeater to all files with the extention *.jpg, *.gif, *.png in a directory using the Dir() function?

All other forums couldn't help me, Microsoft wouldn't respond, so you're my last hope!

Allright, no posts...

Well, let me explain it a bit more. I want all the jpg files in the Dir("C:\Path\*.jpg") to be displayed in either a datagrid or repeater.

Why is this so difficult? I mean, I'm a n00b, so if I don't understand things, that makes sence.

100 views and no answer....

i think its safe to assume that no one has tried to do with wht you are talking about....... no need to "bump" up your post

i'd look elsewhere

Before going to forums, you should be looking up the System.IO class. There are also tons of articles about displaying images in datagrids.

I know, but I don't want to add or remove data from a database, so the Dir() function is the most simple thing (I thougt..)

i dont know what would be more involved than:

- Getting a list of the files with
Dim aLocalFiles As FileInfo() = (New DirectoryInfo(whatever directory)).GetFiles("*.jpg")

- Looping through that and put into an array

- Bind array to the control

seems like that would work

perhaps this 25 mins of my time can get you started :)
only thing i don't know how to do (and dont have time to investigate) is how to get mulitple types in that "GetFiles" method

<%@ Page Language="VB" %>
<%@ Import Namespace="System"%>
<%@ Import Namespace="System.IO"%>
<%@ Import Namespace="System.Collections"%>

<script runat="server">
Dim sVirtualDir As String = "/images2/" 'Virtual root to images
Dim blnShowDebugMsg As Boolean = True 'Show the Debug messages

Sub Page_Load(obj as object, e as eventargs )
Dim sLocalDir, ThisFileName As String
sLocalDir = Server.MapPath(sVirtualDir)

If Not Directory.Exists(sLocalDir) Then
  Message.Text = "Directory """ & sVirtualDir & """ (" & sLocalDir & ") doesn't exist!!"
Else
  Dim oLocalFile As FileInfo
  Dim aLocalFiles As FileInfo() = (New DirectoryInfo(sLocalDir)).GetFiles("*.gif")

  if aLocalFiles.Length > 0 then  'There are files to get, so continue
   Message.Text = "Total Files in Collection: " & aLocalFiles.Length
   List.DataSource = aLocalFiles
   List.DataBind()
  else
   Message.Text = "No files found"
  end if
End If
if blnShowDebugMsg then Message.Visible = True
End Sub
</script>
<html>
<head>
</head>
<body>
<asp:label id="Message" runat="server" visible="false"/>
<form runat="server">
<asp:Datagrid id="List" runat="server"/>
</form>
</body>
</html>

It works, thx alot (I edited a little bit, with loop's in it)

Do While aLocalFiles.Length > 0

PicsRepeater.DataSource = aLocalFiles

PicsRepeater.DataBind()

Loop

Do While aLocalFiles.Length > 0

PicsRepeater.DataSource = aLocalFiles

PicsRepeater.DataBind()

Loop

End If

And The ASPX file:

<asp:Repeater id="PicsRepeater" runat="server"><HeaderTemplate>

<ItemTemplate>
<tr>
<td width="100%" valign="top"><a href="Pics/Images/<%# Container.DataItem("aLocalFiles") %>"><img src="Pics/Thumbs/<%# Container.DataItem("aLocalFiles") %>"></a></td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>

If you want, you can help me, but I think I can handle this one, it's more like to inform you.
