Dear Sir/Madam, I copied this code from gotdotnet.com tutorial. //it is adding items to a combobox1(cmbStyle) StringIntObject[] aStyle = new StringIntObject[3]; aStyle[0] = new StringIntObject("Simple",(int)ComboBoxStyle.Simple); aStyle[1] = new StringIntObject("Dropdown",(int)ComboBoxStyle.DropDown); aStyle[2] = new StringIntObject("Dropdownlist",(int)ComboBoxStyle.DropDownList); cmbStyle.Items.AddRange(aStyle); comboBegin.DropDownStyle = (ComboBoxStyle)aStyle[1].i; comboEnd.DropDownStyle = (ComboBoxStyle)aStyle[1].i; cmbStyle.SelectedIndex = 1; //This is adding items to a combobox2(cmbDrawMode) // Sync ComboBox draw modes to DrawMode.NORMAL StringIntObject[] aDMO = new StringIntObject[3]; aDMO[0] = new StringIntObject("Normal",(int)DrawMode.Normal); aDMO[1] = new StringIntObject("Ownerdrawfixed",(int)DrawMode.OwnerDrawFixed); aDMO[2] = new StringIntObject("Ownerdrawvariable",(int)DrawMode.OwnerDrawVariable); cmbDrawMode.Items.AddRange(aDMO); comboBegin.DrawMode = (DrawMode)aDMO[0].i; comboEnd.DrawMode = (DrawMode)aDMO[0].i; cmbDrawMode.SelectedIndex = 0; i get an error when i run the application saying are you missing an assembly directive please help.

Hi Mahan, You need to define the class StringIntObject as shown below: public class StringIntObject { public string s; public int i; public StringIntObject(string sz, int n) { s=sz; i=n; } public override string ToString() { return s; } } Regards, Anu.
