placing user controls in a form...

I created a user control and want to add it in a form using:

Code:

---

  this.Controls.Add(attachmentControl);
  attachmentControl.Visible = true;

---

But the next time I wish to add another one I find that its added "behind" the older one.Are there any commands to place these controls serially (i.e. one below the other) ?

Why you don't use form designer. Want to code it by yourself?
I don't know C# but take a look at this

Code:

---

this.comboBox1.AllowDrop = true;
this.comboBox1.FormattingEnabled = true;
this.comboBox1.Location = System.Drawing.Point(62, 59); //Look at this
this.comboBox1.Name =  "comboBox1";
this.comboBox1.Size = System.Drawing.Size(121, 21);
this.comboBox1.TabIndex = 0;

---

Thanks GanglyLamb

>>I converted -> to . but I don't know what to do with ::.

The same, it becomes a .
