Below given code are working fine on my machine.
Note: Which I have mark as bold provide there your gmail id and password.
MailMessage MyMailMessage=new MailMessage();
MyMailMessage.From = new MailAddress("g.parwez@gmail.com");
MyMailMessage.To.Add("g.parwez@gmail.com");
MyMailMessage.Subject = "Parwej Testing !!!";
MyMailMessage.Body = "This is the test text for Parwej Ahamad";
SmtpClient SMTPServer=new SmtpClient("smtp.gmail.com");
SMTPServer.Port = 587;
SMTPServer.Credentials =new System.Net.NetworkCredential("yourgmaid", "yourgmailpassword");
SMTPServer.EnableSsl = true;
SMTPServer.Send(MyMailMessage);
After that you can check your attachment code.

I am trying to read a sql database so the same rows will not be inserted. I already got the connection I just need to know how to not insert the same row twice. I am using the VB language. Any ideas?

But now you are saying u need to insert it twice....
Pls be a bit more clear every time u post a question, otherwise u ll keep howling like a donkey...

This is how I am trying to get it. For example, If I insert a row into the database that have a department name HR and a username user.name and I try to insert another row that has the same department and username, the new row can't be inserted because the department and username already exists.

You could first select the record you are trying to insert. If you get something back, then you know it already exists.
I would also recommend that you research using a DataAdapter object which, if setup correctly, can help a lot with inserting, updating, deleting, etc. You could start your research with some of these articles.[^]
Hope this helps.

Read up on unique constraints.
Generally your database shouldn't let you insert "bad" data, so you enforce this with constraints. Then your UI probably should deal with the situation nicely, either by checking first, or handling the exception that gets thrown when you try to insert the second row.

I have an 'edit' button in each row created by my repeater. The problem I'm having is none of the controls I have in my ItemTemplate will save their state.
Everything I've read said that controls listed in the template will automatically remember their view state. I can't even seem to get them to remember their state from one function to the next. Does DataBind() somehow wipe their state? Also, on a postback, why does the repeater call Repeater1_ItemCreated() twice for each item?
I've made a really simple test app and it still doesn't work. What do I need to do to get this to work? In this app I'm simply trying to get each row to remember if they are in edit mode.
Thanks,

Hi all,
My site got hit with SQL injection attack, and I'm now looking for ways to ensure that this won't happen again.
Actually I thought I was pretty well covered against SQL injection attacks, but apparently I was wrong. One technique I've been using is when I pass ID's through querystring is to do something like this:
String strID = Request.QueryString["ID"];
if ( !String.IsNullOrEmpty( strID ) )
{
int nID = Convert.ToInt32( strID );
myDBWrapper.GetSomeData( nID );
}
public MyDataCollection GetSomeData( int nID )
{
String strSQL = String.Format( "SELECT * FROM MyData WHERE ID = {0}", nID );
}
Would you consider this code to be vulnerable? I'm aware of SQL parameters, and I use them in other circumstances, such as when inserting into tables. But I've always believed that it wasn't necessary in these situations, because the conversion to Int32 would fail if the Query String parameter did contain some malicious SQL statments.
Any comments?
Regards,
Daníel

This is my take on an injection attack
If you have a textbox which a user can enter data into and that textbox value is then used in a query which is written into your c# code (i.e. not a stored procedure) then you are at risk of attack unless you can filter their input.
To answer your question I'm not sure if the above code would be vunerable but my using the above methodology you might be able to work it out yourself
hope this helps

Yes, I'm using command parameters for all values which the user can enter.

...but bear in mind that input fields on web forms are not the only method a hacker has of passing data to your application - they can also use the QueryString and even cookie values, so if you utilise any of these you msu also validate them.
Basically, validate ANYTHING that gets passed to the database. Life is much easier if you don't allow HTML to be posted, but unfortunately a lot of clients want it nowadays... but, for example, no-one should ever be allowed to pass "<script" back...
|
|
|
|
|
Agreed. I'm aware of this.
What I wanted most was some advise on the initial code, i.e. if the approach described is vulnerable in some way. Any ideas?

Daníel

Well I hope it is, as it's essentially what I do as well in such a case... basically, you have ensured that nothing but an integer can get passed to your query, so you should be safe...

I am showing one image initialy. Now I need to manipulate with image color and i am changing image color in same image and once again i m assigning the image source as same image name.Physically it is changing color and showing changed colored image on drive but on page it is not refreshing. I mean it is not showing that changed color image. If i assign some other image name to its source and put one alert msg and then i assign the same image name then it is showing that changed color image. i dont know why withou alert msg it is not showing that changed color image.

|

Ive found in the past that I have an image which I change in my file location but when I go to the webpage it didnt change. I deleted my cache and then it was updated. maybe try that.
Post back if that doesnt work

The image is cached in the browser, so reloading the image will only load it from the cache, not from the server.
You can add a querystring to the url that changes every time you reload the image. That way the url is different every time, and the browser has to get the image from the server.
Despite everything, the person most likely to be fooling you next is yourself.

SqlDataAdapter da = new SqlDataAdapter();
...
...
...
da.Update(tbl);
where tbl is DataTable object and it has records.
for above code I am passing some command
da.command=....
It has more than one insert query so if error occur in any one insert query then everything should be roll back from database.
how to maintain transaction in da.update(tbl) or any other option to roll back if error occur or da.update(tbl) itself not insert anything if error occur in anyone.
thanks
You get the best out of others when you give the best of yourself.

Hi, According to me this is possible through the Transaction Scope. Please a test with this.
using( TransactionScope tx = new TransactionScope()))
{
da.Update(tbl);
tx.Complete();
}
