paths in code

I'm not quite sure what you are asking, but I think this may be helpful:

When you want to convert a relative web URL to the local path on the machine you can do:

string localPath = HttpContext.Current.Server.MapPath(relativeUrl);

(note, that's C# syntax)

You use then when you want to save a file to the file system.

 

Excuse the simplicity of this, but I have looked all through the asp.net2 book I am working through as well as seached this forum (path brings up no results, maybe I'm the first one to need it .

My normal way of dealing with pictures (when I used old fashioned php that is ) is to build the picture database in an admin section of the code, so all I have to do is upload a picture, resfresh the database and the other code fits the picture into a group. (I'm a firm believer in letting the code do the mundane work).

But for some reason I can not work out a path that works in a directory search. This is on my local machine, haven't uploaded to the site yet.

Protected Sub Page_Load( ... )
If Not Page.IsPostBack Then
picCollectionPersonal = New Collection
fillPictureCollections()
End If
End

(I know the 'new collection' is in the wrong place really, just wanted to show you what I have done)



Private Sub fillPictureCollections()
Dim lString As String
Dim iCount As Integer


Dim lPath as String


lPath = "~/images/personal/*.jpg"



lString = Dir(lPath, FileAttribute.Normal)
iCount = 0
Do While lString <> ""
picCollectionPersonal.Add(lString, iCount.ToString)
iCount += 1
lString = Dir()
Loop
End Sub


I have tried alsorts in 'lPath' but don't get any list. But, if I use 'lPath = "*.*" I get the list of the files in,


C:\Program Files\Microsoft Visual Studio 8\Common7\IDE


So any relative path isn't going to work. Can I not use relative paths like this on the local machine, or is there some secret trick you all know about but I have missed?

rassler,

Another useful path specifier is "~". which maps to the root of the application.

You can also use Request.ApplicationPath to get the application path of the app.
