DataTable myTable=myDataSet.Tables["myName"];
ArrayList myArray=new ArrayList(1);

foreach(DataRow dr in myTable.Rows)
{
myArray.Add(dr["myColumn"]);
}
myCombo.DataSource=myArray;

Not tested.

Now I understand but can I have more explanation about :
write it's values to array list or array an use array as source. ??
Forgive me ,I'm a beginner
Thanks

DataSet is much more complicated to use as source to combobox. Use proper datatable column from dataset, write it's values to array list or array an use array as source.

Hi again,Wegierski
I tried another way but need help: I defined ComboBox as public in its form (second)
& in the first form I created an object(J) from second form & wrote this in suitable place:
J.MyComboBox.DataSource=myDataSet1.Joue;
J.ShowDialog();
After debuging I found this in comboBox:System.Data.DataRowView
So,what do you think?
Thanks

Hi wegierski,thanks for your help,but there is a problem:
I created a DataSet property ,as you said,in second form after i have
define dataset as public in first & I worte this statement in Load event
of second form:MyComboBox.DataSource=myDataSet1.Joue;
when debuging ,I found nothing in MyComboBox!!

Thanks again.

If second form is created from first, create a dataset property in it and set after creating. If not, find first form and do thesame, but from second form - dataset in the first form must be readable - for instance public.
