Uploading anImage to a folder specific to username 1

[autumnEND]

Hi, ive been trying to enable users to add images to a folder based on there user.identity.name

so if the user is logged in as TEST
when they add an image it would make a folder inside the images folder called TEST

C:\\images\TEST

also would there be a way to check if the folder was allready created? if it was still uplaod the file into the folder

ive been using this code to add files

If FileUpload1.HasFile Then
Try
FileUpload1.SaveAs("C:\\Files\\" + FileUpload1.FileName)
LblStatus.Text = "File Successfully Uploaded"
Catch
LblStatus.Text = "Unable to save the file"
End Try
Else
LblStatus.Text = "You have to select a file to upload"
End If


also is it possible to set allowable extensions to such as .jpg, .bmp etc?

im new to asp.net , so any help would be greatly appreciated

im not sure how to implement the method above

Using TipGiver's example above, you simply need a treeview named trreview1.

i added a treeview called Treeview1 and added the cose into the aspx.vb page im wanting to display on :

Protected Sub TreeView1_SelectedNodeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TreeView1.SelectedNodeChanged

Dim tn As TreeNode
Dim myimages() As String = IO.Directory.GetFiles(Server.MapPath("images") & "/" & User.Identity.Name)

For i As Integer = 0 To myimages.Length - 1
tn = New TreeNode
tn.ImageUrl = myimages(i)
TreeView1.Nodes.Add(tn)
Next

tn = Nothing

End Sub

but when i view the page it doesnt display any of the images when the user is logged in.

also would it work using a query string

 

[TipGiver]

No, add the code in a button click event or in page load event. For the second, you will need to know the users name. That way you can use a query string (user.identity.name). Check the .redirect and the .transfer of the page object

 

[ca8msm]

You've put the code in the SelectedNodeChanged so the image paths will only be loaded then rather than when the page is loaded.

its working now, the only problem being if the user uplaods a picture with spaces in such as "picture one.jpg", then it wont display , it displays the red cross instead.

i guess id need to rename the images somehow when they are uplaoded.

 

[TipGiver]

I have no idea what are you talkng about. I do not have such a problem.

 

[autumnEND]

i dont know then.
it wont display and if i check the path of the image i get

file:///d:/inetpub/

http://wwwroot/test/images/admin/no%20photo.gif

seems odd how it lists it as file:///d and not http://

 

[autumnEND]

would it be a problem that i run my application from my computer,its set up as a server.
maybe that causes the problem with the file://d extension

 

[autumnEND]

is there a way to make it display the link to the image

such as a link like this

http://siteaddress/v1/images/

.... etc

rather than have :

file://d/inetpub/images .... etc

ive been looking for a solution but cant find one anywhere

any pointers would be greatly appreciated

 

[ca8msm]

Yes, you must know what the virtual path to the file is, so simply use that instead of Server.MapPath.
