Re: How to handle request validation exception

Brij1-Jan-10 7:20

Why do you want to catch exception at server side.. you can do it by custom validator also

but if you want to do it server side only... put ValidateRequest="false" in page attribute.. Now .Net allow this request to go server side.Now make your handler to throw some exception according to your need and show the message accordingly..

I am writing a code which send Email to the respective email address. First time its working fine. But after sending my first email its not accept my program and I am not able to send email again. I put the code snippet here.

Dim smtpServer As New SmtpClient
Dim messageSTR As New MailMessage
Dim strAddress As New MailAddress("Email address", "Name") 

messageSTR.From = strAddress 
messageSTR.To.Add("To Email Address")
messageSTR.Subject = Me.txtSub.Text
messageSTR.Body = Me.txtMailBody.Text

smtpServer.Host = "smtp.gmail.com" 
smtpServer.Port = 578 

smtpServer.Credentials = New NetworkCredential("user id", "user pass")

smtpServer.EnableSsl = true
smtpServer.Send(messageSTR)

What is the problem? Why I don't send the second mail?

Exception Shown: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 209.85.129.109:578.
Error Message: Unable to connect to the remote server

At first, I send mail using default port number. Then I take it from the user and then creates the problem.

Hi,
I have a project requiement to build a facebook like website in C# & ASP

In this website:
- Allow at least 3 types of users: unregistered visitor, registered user and moderator
- Allow users to create profiles and upload images etc.
- Any user can search for people and view public profiles
- Registered users can create a profile which can connect with other members or groups of people can join. Each user can set their profile : public or private.
- Each user can add albums with pictures. Every picture may receive comments from friends or from other users which the user can accept or reject
- The user has one mailbox that can communicate with other members of the site.
etc etc

I am a novice when it comes to coding, I have so far been able to create profiles and allow uploading of images and returning but I seem to be lost at doing stuff like retrieving a user's images when his profile picture is clicked etc etc. Are there any references you guys could point me to that would give me more information on developing this. I like doing things on my own but would be useful if I could refer to a source for more info when I got stuck.

Thanks so much for helping!

Kool

Controls property on a Page gives all child controls. Is that what you are looking for?

Something like,

void IterateChildrenRecursively(Control control)
{
   foreach(Control c in control.Controls)
   {
       // Do processing using c
       // Go recursive and process the children of c.
       IterateChildrenRecursively(c);
   }
}

// Assuming this code is on page
IterateChildrenRecursively(this); //Starting with top level controls on the current page

New year wishes to you too. Smile | :)

Best wishes,

Continue C++ managed AND unmanaged project in VB

I was given a started c++ project (written using vs 2005) to finish. It includes managed and unmanaged code.

I would like to continue the project in vb.

From searching the web, it seems like I have to compile it as a dll (or 2 different dlls?!), then access the dll from a vb project.

Is this do-able?

Is there anyone that can guide me, step by step in how to do this? I don't have any experience in creating dll's and I'm feeling quite lost by now.

Thanks a million in advance Smile | :)

Session being lost in a simple test webpage

jpegny31-Dec-09 9:29

Hi,

I'm using visual studio 2008 and it's built in development webserver, with C# as the codebehind language.

I'm trying to make a simple webapp in which you click a button which sets a session var (that part is working) and in the pageload
i'm checking to see if it's a postback and if the session is not null. problem is that every time the session is null.
I have done this successfully before with visual studio 2003 and on IIS.

Here is the relevant code:

<br />
protected void Button1_Click(object sender, EventArgs e)<br />
        {<br />
            Session["testvar"] = 25;<br />
<br />
            /*<br />
            if (Session["testvar"] == null)<br />
                Response.Write("s is null");<br />
            else<br />
                Response.Write("s is NOT null");<br />
            <br />
            */<br />
        }<br />
<br />
<br />
        protected void Page_Load(object sender, EventArgs e)<br />
        {<br />
            if (IsPostBack)<br />
            {<br />
                int x;<br />
<br />
                //x = (int)Session["testvar"];<br />
<br />
                <br />
                if (Session["testvar"] == null)<br />
                    Response.Write("test var is null");<br />
                else<br />
                {<br />
                    x = (int)Session["testvar"];<br />
                    TextBox1.Text = x.ToString();<br />
                }<br />
<br />
                <br />
<br />
            }<br />
        }<br />
<br />
<br />

Any help is appreciated.
Thanks

I've haven't set either of those, everything is left to default in web.config, the only thing I enabled was debugging.

From my readings the default of inProc should be sufficient.

Based on the code above, you have to click the button twice in order for the session var to show in the textbox.
this is because the execution goes in this order:
Page Load
--You click Button
Page Load
Button Click
