NaN stands for not a number.
You need to see whether the name you are passing is correct.

i am able to get date in the field while debugging but when assigning it to variable it giving value NaN.

it means you tried to divide by zero, or otherwise created an invalid value.

And what is wrong with that code?

Let me first say hello, as this is my first post to these forums.
My question is, say that I want to log an entry to a database through a stored procedure when a page is requested. The log is merely a counter for recording how often a page is being requested. This stored procedure may take longer than I would like to execute, and I do not want to affect the performance of the page. This page may also have page caching enabled.
So, I'm thinking there are two ways I can go about this. I could execute the SP asynchronously on the load event or I can execute the SP from the unload event after the page has rendered. I would think the unload event would make more sense since the load event will not fire if the page has been cached. But this leads me to my original question. Does the unload event fire when page caching is enabled? If not, is there a better way to log for pages that are being cached?
Thanks for your help.

Why dont you handle that event on a page with/without caching enabled and set a breakpoint and see if the breakpoint is hit
Then you could post your results
It would be good to know it

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.
