Oh sure, make me do the work. 
I went ahead and tried it and the unload event did not fire if cached on the server side. I had a feeling it wouldn't, which is partly why I made the post. What techniques do others use to capture stats on cached pages? I was thinking of creating a 1x1 image file served by a generic handler to log page hits.
Are there any other/better ways to do it?

Just handle the beginrequest in the global.asax
I dont think a call to a stored procedure will take too much time
If you only want to count requests you can save a temp variable in the application object and save it on application end or every n minutes
Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs)
'Do your stuff
End Sub

Wouldnt this image be cached on client side and you would only count the first request??

Thanks, I'll give that a try. I'm sure the performance difference wouldn't be that noticeable, but I wanted to avoid it if possible.

It shouldn't be as long as the response headers are set appropriately.

I really hope that somebody out there reads this and responds. I'm having a real nightmare here and just to top it off Im not even a seasoned developer!
I am trying to create a treeview that will display multiple levels of users (a network marketing program).
I have an MS-Access table containing:
memberid (unique)
membersponsor
membername
imagetodisplay (contains a url to an image of the level of the user in the program ie junior, senior etc)
At some stage (before .net) it was possible to use this structure because you simply told the application the node id where to wanted to insert the record but now it seems this is not the case. I am firstly told that this is not hierachical data (which, if you take the sponsor / memberid into account, it actually is).
Some sponsors have no members under them while some have hundreds. How do I get this into a form that a treeview will recognise? All I want to do is display the membername and the image.
I am using vb.net on visual studio 2005. The treeview is residing on an .aspx page (if that makes any difference)
I have found various references on this site about first writing to a dataset and then using various classes to do this but even if I download the code and just change the dataset it doesn't work. I think this has something to do with the fact that the sample was written for only two levels whilst mine may have numerous levels deep.
PLEASE can somebody help.
Thanks
Steve

If you may have many levels, you need to do it recursivelly

Thanks Alexei
Can I ask you a favor. I am anyway going to post this message in another forum but maybe you can have a look and see if you see something wrong with it.
Thanks

I didnt read your code, you didnt mention if it os working or not, so i dont know what to look for
All i can give you is an example i used:
Public Sub FillNode(ByVal ID As Integer, ByRef RootNode As TreeNode)
Dim Node As TreeNode
Dim Rows As DataRow() = Me.tbl.Select("FatherCategoryID=" & ID, "Name")
For Each R As DataRow In Rows
Node = New TreeNode(R.Item("Name"), R.Item("CategoryID"))
Node.SelectAction = Me.SelectAction
Me.FillNode(R.Item("CategoryID"), Node)
RootNode.ChildNodes.Add(Node)
Next
End Sub
For this example, there is a table with all the rows called tbl. The struct for the table is:
CategoryID, FatherCategoryID, Name
And this function is called sending the root node of the treeview and the id of the parent node
I hope this helps you

Hi Alexei
Sorry for being a pain in the &%^# but I am still having some difficulty.
I tried the sample you gave me but couldn't get it to work.
Then I tried the following:
While dr_ID.Read
'Find a node matching this node value
Dim Nodx As TreeNode
Dim containernode As New TreeNode
For Each Nodx In Me.TreeView1.Nodes
Nodx.PopulateOnDemand = False
If Nodx.Value.ToString = P.ToString Then
containernode.Value = dr_ID.Item("MembersID").ToString
containernode.Text = dr_ID.Item("MembersName").ToString
Nodx.ChildNodes.Add(containernode)
Nodx.SelectAction = TreeNodeSelectAction.Expand
End If
Next Nodx
End While
It populates the root node as well as the first level of children but it seems that the "For Each Nodx In TreeView" doesn't actually return a reference to the children. Is this true? the "P" that you see is the parentid which the childnode has to be created under whilst the rest is pretty much explanatory.
Can u suggest anything else?
Regards
Steve

I think your comparision is wrong, Set a breakpoint and see whats in each variable
I dont know what P is since your explanation didnt explain it

What would you call the gmail "more actions" menu? Is there an open-source version of that style menu?

A customised DropDownList.
Todd Smith wrote: Is there an open-source version of that style menu?
Do you nead one. You could use the existing DropDownList ASP.NET control with AJAX or AutoPostBack set to true to accomplish pretty much the same.

Hello all. I'm using the asp:FileUpload control to, well, upload a file. I get the data and save it into a local database as a binary. It all works well.
However, I'm having a problem with the Content Type. When selecting a Word document, its content type (FileUpload.PostedFile.ContentType) is "application/octet-stream" rather than "application/msword". This will make my app not behave as expected when the document is retrieved (since I can't state a correct content type so that the document is opened by Word).
The client machine has Word installed, but the server doesn't. Do I have to install Word in the server? I was reading that the Content Type is taken from the client machine, so this shouldn't be a problem. I'm I missing something here? The MSDN documentation doesn't say a thing about the content type.
Thanks in advance.

The asp control is just an input type=file, b/c that's the *only* way that a file can be uploaded from a browser using HTML. I'd suggest you need to work out it's a Word doc from the file extension.

I was thinking the same. However, it wouldn't work for non-common extensions (for instance, there's an app that has its own extension, and so on). If I don't find a better way, I'll have to do it this way.
Thanks for the answer.

What are you trying to do with the file once it's uploaded to your server?
Todd Smith
|
|
|
|

It's some sort of document flow, so I store it in a database and many users have to approve/reject it. I need the content type so I can show it to the user by simply writing the binary to the HttpResponse object. I guess I'll have to try something different (Christian's suggestion, most likely).
Thanks.

How to maintain Seesion in windows application
Rickey
|
|
|
|
|
Windows applications are stateful, therefore there is no need to explicitly store session state like there is in an ASP.NET application (which is stateless).
|
|
|
|
|
I want that if User is not using the application for 20 minutes then he hase to login again.
Rickey
|
|
|
|
|
As he explained that Windows Apps are stateless and does not maintain session, you will need to write custom code for it.
Please remember to rate helpful or unhelpful answers, it lets us and people reading the forums know if our answers are any good.
|
|
|
|
|
Then you'll have to write some sort of custom logic for that. You could create a class that maintains a "last used" timestamp. Each time your user does something, event calls a method in the class that updates the timestamp. If the method detects that the time now is greater than 20 minutes since the last time, it can initiate the login form - Your application would then be unusable until the user has logged in.
