The asp:LoginStatus

I can display the login status using the <asp:LoginStatus> tag.

Unfortunatelly, the object LoginStatus seems not to provide an attribute to
test it.

How can you read from the code (VB script) the login status?Progman
if page.user.identity.isauthenticated then
... user is logged in
else
... user is not logged in
endif

Good Luck

The Basics

Hi,

I am very new to ASP. I am trying to make a secure site and I have some general questions.

Does the HttpSessionState object exist in the client's browser oron the IIS server? I assume that it must exist on the server or else itwouldn't really be any different than a cookie. Is this correct?In what order do events occur on the server when an HTTP requestis made. I am assuming that the request is made, the server gets theclients cookies, the server checks the web.config file, then the serverexecutes any necessary scripts and returns a webpage. Is this correct?Is there a nice tutorial about modifying the web.config file? Forexample, a tutorial which teaches people which XML tags do what in it?
Thanks a lot,

P10001.Session is on the server
2. there are a few more steps than that - search on asp.net lifecycle - though .Net isn't a script technolgy - morecorrect to say server creates objects- performs sub and functions - then renders html page
3.http://www.sitepoint.com/article/web-config-file-demystified
Thanks a lot.
Okay, the lifecycle does give me a lot of information that I am lookingfor, but it doesn't really mention (at least the pages which I readdidn't mention) when web.config is accessed in order to determineauthenication info etc. So I am still missing some important steps inthe lifecycle of a request.

The web.config link was also very helpful but I still don't know when the server uses it.

The best place

Hi,

where is the best place for setting components on load but only if
this is not a postback?

protected void Page_Load(object sender, EventArgs e) {
if(!Page.IsPostBack) {
//here?
}
}

yup :-)
That's not a terrible place, although the Page_Init event might be better
depending on exactly what it is you're trying to do.

the best way to have some information accessable to all pages?

hello all,
I need to have access to some details in all my pages eg a Person object.
what is the best way to do it?
store in session object? or pass them through the QueryString or Application
variables etc?
what is the best and efficient way?It really depends on the nature of the application. Overall, I am not fond o
f
putting everything in hidden tags so it can travel on the Query String. It
potentially opens security holes.
Where you store information depends on the nature of the information.
If it is linked to the user, cookies are an option. For security, you can
send the user's token instead, or link it to the session ID. This will
require grabbing the information with each return, but it is safer than
storing in the cookie.
For session specific information, you can use the Session object as a cache.
You can also use the cache manager functionality of ASP.NET.
For page specific information (like the Person object is the person being
worked on, not the person using the app), you can use ViewState.
As I stated at the beginning, it really depends on the nature of the
application.

The Cache object

Hello!

Is there a way to get to the Cache object in some other way than the
current contex?
I mean - the Cache is independant from the request so I would expect to
see some kind of Cache.Current property or something like
HttpContext.Current, but unfortunately I've been unable to find one.
When it could be usefull is for example a situation when I put some
task to be done every few minutes on the server - independent from the
requests comming in.
The way I do it now is to catch one of the Requests, get the Cache from
there and store the reference to it in some global/static variable.

You might need to reference the System.Web assembly, but you can use it for
any type of application, including windows forms, console, web service...

Hello!

Yep, I'm already referencing it, but! What I need is a way to get the
Cache object without the Context object which is only available during
request processing which is not allways the case when some code on the
server runs as in my example with tasks running on the server every few
minutes. The importatnt part is that the tasks are run even if no one
uses my application i.e.: no one is requesting pages at the moment and
there is some Timer object stored in the Application state which fires
some tasks.

You can also consider using the Caching Application Block in EL 2.0. The
API is similar to ASP.NET's Cache class.

The Cache object...

I need to get some clarification on how this object is being implemented:

1. Global to the entire application (single server) -- is this on a per user session? Meaning Cache for user session A will be different from Cache for user session B?
2. What could cause the Cache values to be unreliable aka -- not available or cleared out (prior to expiration time)?

Thanks, Rob.

Hi,

Cache is global to entire application. It is one and the same for all users e.g shared for all users. Session is the user-specific data storage on the server.

Cache values can be cleared under memory pressure (priority depends on if one is explicitly given when cache item is added), and when AppDomain restarts: application pool restarts, web.config change, multiple file operations, maximum number of recompiles etc etc

Therefore you should check cache item for null reference before trying to access it. Steve Smith ahs written excellent article about ASP.NET caching (it's old but still valid):http://msdn2.microsoft.com/en-us/library/aa478965.aspx

Thank you for the response.

So if I were to add something like TextBox.ClientID (as the key) to the Cache, it would be possible for another user session to overwrite or get that same Cache item if they used the same TextBox.ClientID?

Rob.

Yes because it it is essentially one and the same storage for all users.

Hello again.

This problem relates to a Business Object that I've created. I get the above error when I try t call a Sub within the business object that inserts into the database. I have various other Subs and Functions that Select from the database and they don't seem to have a problem. I can't see where the connection is being left open... But I've been staring at this all day now so theres a good chance I'm missing something obvious...

The VB for the business object is below. The sub in the aspx page that calls it is:

Any hints greatly received!

Thank you for your time

Shaun

Wow.. I don't think the problem lies within the code that you have bolded but within all the functions that return DataReader objects. You're going to have to pass them as:
return objDataReader(CommandBehavior.CloseConnection)
and then in your main code that is actually calling the function and expecting a reader in return you must do:
dim dr as SqlDataReader
dr = Class.MethodReturnsDatareader
dr.close()
Also, you may want to add Finally blocks to all those Try blocks and explicitly close the connection there. Because if any of those methods error out, the connection is still open...

Thanks Optik.

I will try what you suggest. I'm a bit confused though, as I've simply adapted examples out of my Teach Yourself ASP.Net in 21 Days Book. Would you be able to shed a little light on why I need to use objDataReader(CommandBehavior.CloseConnection)? What was it that I was doing wrong?
Many thanks
Shaun

Hi Optik

I would just like to say that this did infact solve the problem. So this issue is now resolved.

It would be good if I could just understand why!?!

Many thanks for your time

Shaun

Quoted from MSDN
"While theSqlDataReader is in use, the associatedSqlConnection is busy serving theSqlDataReader. While in this state, no other operations can be performed on theSqlConnection other than closing it. This is the case until you call theSqlDataReader.Close method. If theSqlDataReader is created withCommandBehavior set toCloseConnection, closing theSqlDataReader closes the connection automatically."

Cheers me dears!

The continuing adventures of a ASP newb

Hi there,

OK - So I have run into a problem. I have created a shopping cart, the cart is an object that gets created when the user logs in. That all works great. My problem is this.

I have a page for viewing the cart, what I want to do is loop through the cart and show the details for all the items. I mean I could just bind it to a datagrid view (I think) but I would like a little more control over that. The problem is if I loop through my array and say print some HTML it prints it first thing on the page :( That of course doesn't work... How can I get it to put my HTML where I want it? Like inside of a DIV tag?

Being a total newb to ASP programming I am not sure what the best approach to something like this is. But there has to be a lot of cases where a web page has some sort of object of varying length and it needs to be printed to the page in some fashion.

Can anyone point me in the right direction?

ThanksPlace an asp label with runat =server within the div tag. Then send the html output to it in the code behind:

<div>
<asp:Label runat="server" id="myLabel"></asp:Label>
</div>

Then in the code behind:
myLabel.Text = ...

That was a very fundamental ASP.NET question. Are you sure you should be creating a shopping cart? :ehh:

Because of the nature of your question, I take it you don't have a lot of knowledge of the ASP.NET controls. First thing to remember, do not use Response.Write. That's something from the classic ASP days which you should rarely ever need to use.

Tutorial:
http://www.asp.net/Tutorials/quickstart.aspx

The DataSet: I have doubts

Here are my doubts about the dataSet object. These doubts may arise from my not understanding this object properly so please let me know if this is the case.

i see these problems:

1. if a user closes the page mid session i lose my in memory dataSet so all the dataGrid editing my user has done since the database was last updated is lost.

2. when updating the parent database I need to fill the dataAdapter first in case anyone else has edited the rows beforehand. all this toing and froing is expensive.

Also, how do i decide to update the parent database from the dataSet. Can I do it automatically i.e. on a timer or do I do it after every 5 dataGrid row edits?

thanks.1. You would lose any data had you hand written the text boxes and filled the table dynamically with them. It's not the fault of the DataSet or some weird communication.

2. Again, you should be checking data validity before hand any way. The only difference here, with DataGrids, is that you know exactly which row was modified before hand very easily.

3. [How do I...] Why not whenever the user presses update? The few times that I have used datasets I have never held them in the session. I bind them to a datagrid and forget. When the user edits, the info I need to update the row is right there.

The difference between creating an instance of an object

Could someone tell me in plain english was is the difference between

Dim MyObject As SomeType

and

Dim MyObject As New SomeType

and

Dim MyObject = New SomeType

Dim MyObject as SomeType = Creating a variable that holds an object of SomeType.

Dim MyObject as New SomeType = Creating and instantiating an object of SomeType.

Dim MyObject = New SomeType = Invalid syntax in vb.net. You need to specify the default type as variant is no longer supported in ASP.NET.
Ok, now I understand.

So if I have something like Fruit.Apple and Value is part of this as in Fruit.Apple.Value, I can do this...

Dim Food As Fruit.Apple
Food.Value

It looks like a way of shortening the name of an object.

Now, I have another question. How do you know when is the appropriate time to create and instantiate a new object rather than just use the above method?

Sorry if my question seems too easy, but I didn't do much of this stuff in regular ASP.
Well yes and no.

Lets think of this another way. Lets take your Fruit object. Your fruit has properties - color, weight, type, etc. You would create a class that describes this like so:

Public Class Fruit
 Private _type As String
 Private _color As String
 Private _weight As Decimal
 Public Property Type() As String
 Get
 Return _type
 End Get
 Set(ByVal Value As String)
 _type = Value
 End Set
 End Property
 ' Add other properties for color and weight also
End Class

Then in your code you would instantiate a new Fruit object like:

Dim objFruit as New Fruit
'Then set properties of the fruit
With objFruit
 .Type = "Apple"
 .Color = "Red"
 .Weight = 2.2
End With

It is appropriate to create a class whenever you are going to possibly reference the object from multiple places in your code.

The easiest way to save data into a text file on server side - Help me please

Hi guys, I'm new at ASP and all I wanna know is, what is the simplest code for gathering info from my website visitors (using the FORM object) and saving it to a text file (*.TXT) on the web server? The whole procedure. I know it's lame, but is there anyone out there, that could help me with this one? Thanks guys.

You could do something like the following. Here txtName and txtAddress are textboxes. Similarly you can add all the controls that you want to save.

The collected data is saved in the current directory on the webserver in a file called Test.txt. All subsequent saves will be appended to the same file (change the last parameter
to false to overwrite on every save)

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim s As String
s += txtName.Text + vbCrLf
s += txtAddress.Text + vbCrLf
My.Computer.FileSystem.WriteAllText(Server.MapPath("Test.txt"), s, True)

end sub
