A link is simply a href in an HTML block of code. Send them an HTML page with the security code appended to the link as a querystring. If the user doesn't accept HTML mail, they'll have to copy the address into the address bar manually.
As a side note - you should really have asked this in the ASP.NET forum.

Hi,
Just a basic question.
I want to display the progress of an operaton that has been carried out in a seperate thread(other that UI thread) on the progress bar in windows form.
For E.g : I wanted to display the staus of database operation in a label and update the progress accordingly. The database operation consists of below operations.
- Establishing connection
- Retriving data from a query
So whenever these operations finishes, i want to update the status in the label also the progress bar concurrently.
This requires a cross-thread operation. I am able to update the UI once all the operation is finished but not part by part.
Also, how can we notify the UI thread about the completion of worker thread?
What is the best way to acheve this?
Thanks in advance!!!

Hi,
best way would be to use BackgroundWorker instead of Thread . See here[^]
And a special hint for you: use Thread.Sleep (250ms might work) in event handler ProgressChanged to give processing time to the ui
Kind regards

If I understand you correctly, you need to update a Label with the status of the connection or the status of running a query? Correct?
You can try the following which I use to identify which files I am currently processing in a Thread.
First I declare a delgate for updating the Label.
public delegate void SetLabel(Control lblctrl, string filename);
Then I define the follwing to control the invoke.
private void setFilename(Control lblctrl, string filename)
{
if (this.WindowState == FormWindowState.Minimized)
return;
if (lblctrl.InvokeRequired)
lblctrl.BeginInvoke(new SetLabel(setFilename),
new object[] { lblctrl, filename });
else
lblctrl.Text = filename;
}
This allows me to call the fucntion from within any running thread. Like below:
foreach (string str2 in Directory.GetFiles(path))
{
setFilename(this.lblFileName, str2);
Hope this gives you some idea as to what I mean. You can do exactly the same for the progress bar.
Excellence is doing ordinary things extraordinarily well.

(statement?true:false)
Ex
int a=5;
int b=5;
MessageBox.Show(a==5?"a is equal to b":"a is not equal to b");

The technical name for this is the ternary operator (sometimes known as the conditional operator) if you ever need to look it up. Did you know that there are other cool operators available in C#? My favourite is the null coalescing operator or ?? . This works by chaining items together until a none-null condition is reached. For instance:
string value = GetValueFromDatabase() ?? GetValueFromConfigFile() ?? "None Selected"; In this example, if a null is returned from GetValueFromDatabase, the code will attempt to assign a value from GetValueFromConfigFile and if this returns null, None Selected is used (as it's the first none-null operator).

We cant know why? because we don't see the code.

Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

We cannot Help until we see the code where you bind the Grid

Good Day Rajeshwar
I dont use Wizards to do my database.
can you do a Check for me. put your code in a try and check if there are any rows returned
SqlConnection cn = new SqlConnection("server=.;uid=sa;pwd=sa;database=Payroll1");
string ssql = "Select * from EmpDetails";
SqlDataAdapter da = new SqlDataAdapter(ssql, cn);
DataSet ds = new DataSet();
try
{
cn.open();
da.Fill(ds);
BindingSource bindgrd = new BindingSource();
bindgrd.DataSource = ds;
if(ds.Tables[0].Rows.count > 0)
{
this.Datagridview1.DataSource = bindgrd;
}
else
{
lblError.text = "No Rows Returned";
}
catch(SQlException ex)
{
lblError.text = ex.Message;
}
Finaly
{
cn.close();
}
Tell me if you get an Error or there are any Rows Returned. I wrote this here, so the logic is correct , just correct the syntax dont do copy and paste and tell me what it does.

Try this sample code
SqlCommand cmd = new SqlCommand();
cmd.Connection = sqlConnection();
cmd.CommandText ="your query";
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
adapter.Fill(ds);
datagridview1.DataSource = ds;

Hi,
I have created a Windows Form as "usercontrol" using vs.net 2003 with c#. In that Form I placed a Panel and below a horizontal scrollbar control. While I am trying to view the extreme right content of the Panel with the help of horizontal scroll bar the panel content is not viewable.(ie Panel content is not moving left- right)
And also I set "this.pnlWorkArea1.AutoScroll = true;" and its showing scrollbar but its not moving beyond the current viewable area.
Example: From the panel i am plotting graph with numbers 1 to 40 only its viewable up to 25.
Please advice me.
Thanks,
Palanivel

Hi,
I have a grid that displays multiple images (the grid can scroll horizontally and vertically)
At runtime I draw rectangles on each of the images which i intend to act as buttons.
I want to perform functions when when the user clicks on these drawn images.
How can I get the coordinates of the click event relative to the location of the cell? ie assuming the top left of each cell is 0,0
Thanks,
Chas

Assuming you have the relevant permisions, you can use EventLog.Delete to delete a particular log. Here's how I figured it out (who knows, this thought process may help you):
First of all, I thought to myself - this is an operation on the EventLog . Now, I know that there is an EventLog class, but if I hadn't known this the name would have seemed a logical place to start.
Then I thought - perhaps it has a DeleteLog entry.
I typed EventLog.DeleteLog into Google, and it suggested that it should actually be EventLog.Delete .
From there, I hopped over to the docs just to check that it was the item I thought it was - job done.

Hi,
Whenever I tried to sort the mail item, it does not effect.
Microsoft.Office.Interop.Outlook.MAPIFolder mItem = TraverseTee(outlook.Session.Folders, "myfolder");
if(mItem!=null)
{
mItem.Items.Sort("Received", false);
int i=0;
foreach(Microsoft.Office.Interop.Outlook.MailItem item in mItem.Items)
{
listBox1.Items.Insert(i,item.Subject);
i++;
}
}
