say for example you created a namespace called samLibray u then need to add the dll to refrence in your project you want to call and add the namespace using samLibray in the class you want to use. then you can create an object instance of the class like samLibray sl1 = new samLibray(); and use the methods and variables using sl.onInit() etc.. Thanks Lisa

all the protected and private methods and variables will be invisible you can only access public methods by referencing to the dll unless the class is a derived class of the parent class. I hope it helps. Thanks Lisa

String.Empty : s); } set { ViewState[Text] = value; } } protected override void RenderContents(HtmlTextWriter output) { output.Write(Text); } protected override void CreateChildControls() { l1.ID = l1sam; l1.BorderColor = System.Drawing.Color.Chocolate; Controls.Add(l1); Controls.Add(new LiteralControl( )); t1.ID = t1sam; t1.ForeColor = System.Drawing.Color.Azure; Controls.Add(t1); RequiredFieldValidator rf = new RequiredFieldValidator(); rf.ID = rfsam; rf.ErrorMessage = Values Needed; rf.ControlToValidate =t1sam; Controls.Add(rf); Controls.Add(new LiteralControl( )); b1.ID = b1sam; b1.ForeColor = System.Drawing.Color.Blue; //buttonCell.Width = Unit.Pixel(1); b1.Width = Unit.Pixel(1); Controls.Add(b1); Controls.Add(new LiteralControl( )); EnsureChildControls(); } protected override void OnInit(EventArgs e) { l1.Text = Enter Data; b1.Text = Submit; base.OnInit(e); } private void b1sam_Click(object sender EventArgs e) { } } } Tks in Adv...

sorry but i cant read any of your code its all messed up and do tell me what error are you getting stuck at ? but taking a closer look at it  it looks like you set all of your functions to protected level which i doubt will not allow you to access unless it is a derived class so try changing it to public methods it should work. Thanks Lisa

did you meant a class library?? if it is then just go to new project and select the option Class Library under the windows in your selected environment and you can start designing the library as and how you need. Thanks Lisa
