' This closes the excel once it is set to nothing after the work is done
objExcel.UserControl = True

'Decide the row from which you want to start reading the excel

strMName = Trim(objExcel.Cells(introw, 4).Value)
strLName = Trim(objExcel.Cells(introw, 5).Value)
strFather = Trim(objExcel.Cells(introw, 6).Value)

How do I read the combobox.text value within the excel sheet into vb ?

I have been working in C# and haven't worked in excel or vb6 lately, I can't go through it now.

But I think you have to get the value from the other sheet where you load up the combo box.
