The old way was to delete all the files from the directory and then delete the directory.
Dhould the directory contasin sub directories, then you will need to recure through them to ensure all files are deleted and then delete the directory. If the directory contains files then you will recieve an error.
Private Sub Form_Load()
Dim MyDir As String
On Error GoTo ErrHandler
MyDir = "D:\Temp"...Leave a comment:

Hmmm.....
To obtain the area of a particular shape is to use a formular that depends on that shape.
Co-ordinants are just a reference number to a datum point.
What is the shape you want to determine the area of? Is it a square? is it a rectangle? is it a circle?, an oval, a trapezium?, a hexagon?
Forget about the word co-ordinates and let me know what the shape of the area is that you are trying...Leave a comment:

Area of a square is side A multiplied by side B
The area of a rectangle is Long side A multiplied by Short side BLeave a comment:

I dont understand why you would want to add a text file to a combobox?
A combobox is for listing items, not file contents.
You may be better using a listbox.Leave a comment:
