Hi Guru's

I'm not good at organizing my sessions and I always find my self scratching my head when ever I'm looking from session variable I created. Is there any technique / way that I could organize my sessions into one holder, hmm something like what Enum can do?

I always port my session variables this way

Session("memberID") = memberID
Session("memberName")= memberName
Session("memberEmail")= memberEmail

is there a way that I could group then and place the group to a session? like placing Enum into session, hmm but not that actually but the idea of placing it.

e.g.

Public Enum MemberInfo
memberID = 1
memberName = "Name"
end Enum

Session("memberInfo")= memberIfo

regards
Dom

Your thinking is very near but Enum cannot work. You should create a Class. Storing your MemberInfo Class to session is:

Dim m_memberInfo As New MemberInfo
m_memberInfo.memberID=1
m_memberInfo.memberName="Name"
Session("memberInfo")=m_memberInfo

Retrieving data from Session is:
m_memberInfo=DirectCast(Session("memberInfo"))

Thanks, that would be a great idea.. hmm but are there any other object which I could explicitly group my session variable on the fly without creating another class?

Also was it a good practice to place class into a sessions?

Where possible, you should avoid putting large objects in session because they will eat up server memory. You also need to pay special attention if your web application is on a web farm.

Hi,
I'm trying to insert the urls into my database using FormView.

and when I'm inserting the url of embed video of YouTube, for examle, I get this kind of error:

A potentially dangerous Request.Form value was detected from the client (dynamic:100="<object width="425" ...")<="" b="">

Can anybody tell me why?

Thank you

It is seing the html tags as evidence of a potential threat - to stop this and force it to allow them, add the page directive:

ValidateRequest="False"

host window component in ASP.NET

Hi,

I am trying to learn how to host window component in ASP.NET.
I have a simple MyTestUserCtrl1.dll with a couple of text boxes in it. It was written in C# 2005 with class definition:

namespace MyTestUserCtrl1
{
public class MyTestUserCtrl1Cs1 : System.Windows.Forms.UserControl
{...
...
... }
...
}

The dll works fine hosted by a window form.
When I try host this dll using aspx:

the control can not be displayed. looks like IE can find the control but refuses to display it(tool tips says "Click to activate and use this control).I have checked the virtual directory is set to script only. Any thoughts?

Thanks for your help

Hi,
I have defined the User control which containg one label and textbox.
<asp:label id="”xx”" …="">
<asp:textbox id="”name”" runat="”server”..">
In the user control class I am defining like this:
Class us: System.Web.UI.UserControl
{
Public string setname
{
Get
{
Return name.text;
}
Set
{
Name.text=value;
}
}
Page_load()
{
}
I am using that user control in another aspx page. In which I placed the the above User control in a Wizard control.
<asp:wizard ..="">
<tt.name id="”ci”"> declaring usercontrol inside wizard.

From this aspx I am trying to set the value for the name textbox which is in User control when the Wizard Finish button is clicked.
Like this:
protected void Wizard2_FinishButtonClick(object sender, WizardNavigationEventArgs e)
{

ci.setname = "hh";
}
But this event is not firing when I remove the User control from the Wizard this event is firing.
And when I write the Page_load of aspx page
Aspx page page_load
{
If(!isPostaback)
{
ci.setname=”kk”;
}
If I put like this in the PageLoad’s !ispostback then wizrd finish event is workng.
Withoyt setting the ci.setname in the Page_load I need to set only in the finish button click.
How to do this?

Thanks

Postback problem from ASP.NET page

LancashireLad10-Aug-07 6:10

I am trying to use a client side confirm dialog box. I have a generic sub (borrowed from an article by Jim Stall) that successfully generates the client side Yes/No dialog box. According to the forums and docs I've read, a postback should only occur if the user clicks OK. This means my server code should only needs to check if OK was pressed.

The behavior I'm finding is that a postback occurs regardless of whether the user clicks OK or Cancel. This means I can't detect what was selected. Can someone suggest what I'm doing wrong?

Here's the server side code:

Public Shared Sub CreateConfirmBox(ByRef btn As WebControls.LinkButton, ByVal strMessage As String)
btn.Attributes.Add("onclick", "return confirm('" & strMessage & "');")
End Sub

The button declaration code:
<asp:linkbutton id="btnDelete" runat="server" text="Delete">

The page load code that calls the button generation code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
eVSUtils.CreateConfirmBox(btnDelete, "Are you sure you want to delete this user?")
End If
End Sub

Any suggestions on why it does a postback regardless of the button pressed?

Thanks!

Have you checked this one?? Custom Javascript Dialog[^]

Michael,
Thanks for pointing me to the blog you did on using the prompt funtion. It's helpful but is not solving the problem I'm having.

I'm a novice Javascript programmer so it may be something elemental that I'm missing. According to articles I've read on using confirm() is that if the user clicks Cancel to the OK/Cancel prompt, nothing happens (which is what I want). If they click OK, a postback occurs and executes the code in my button click event. What I'm finding is that regardless of whether OK or Cancel is clicked, the client does a postback. This means I have no way of knowing whether they clickede OK or Cancel.

Original article: http://aspnet.4guysfromrolla.com/articles/021104-1.aspx
(see response http://www.thescripts.com/forum/thread115874.html)

I hope this makes sense and thanks in advance for any help.

Did you check the sample? There are two parts (using normal js confirm and js custom dialog)in this article. there is a way to know whether the user clicks "delete it" button ("OK" button in your case), "cancel " button and "close" button at the top of custom dialog.

it said:

If the user click “cancel” or “close” image, we call “hideWindow()” function. In this function, we hide the JS dialog and set the variable “g_IsWindowShown” to true. (We also return “false” in this function since we dont want the Server-side code to execute.)

If the user click “Delete It” button then we call “deleteit()” function. In this function, we set the text of textbox to hidden field so that this value can be read from Server-side script. then, we fire the button client event of “Delete” button (not “Delete It” button.) then, showWindow() function will be invoked again. At that time, the variable “g_IsWindowShown” will be true. After that, we just return “true” from this function. So, the Server-side code will be executed.

You are only adding the event the first time the page is loaded. If you do a postback for any reason, the event isn't added to the control when the page loads again.

Verify that the code is actually present in the generated code, and if it is, show us what the generated code looks like.

Thanks for responding.

I removed the IsPostBack on the load event and it made no difference. The confirm function is executing. The generated code is below. If you hit cancel I was under the impression that no postback would occur. However, it does and the button code click event fires on the server when you click cancel. Is it your understanding that a postback should not occur if you click Cancel on a confirm dialog box?

<a onclick="return confirm('Are you sure you want to delete this address?');" id="btnDelete" href="javascript:__doPostBack('btnDelete','')">Delete</a></div>

function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit();
}
}

Thanks for your time.

This is very odd - yes, hitting Cancel shouold stop the postback; and you are also quire correct in that you need only add the JS once, the first time the page is loaded.

There really is no reason I can see why this shouldn't work - unless you have javascript disabled in your browser, perhaps..?

The simple page below, based on your code, works fine for me in both IE and Firefox - try copying it to your web-folder and running it. If it works, then there is something going on elsewhere on your page...

End If
