Stop Statement (Visual Basic)

You can place Stop statements anywhere in procedures to suspend execution. Using the Stop statement is similar to setting a breakpoint in the code.

The Stop statement suspends execution, but unlike End, it does not close any files or clear any variables, unless it is encountered in a compiled executable (.exe) file.

Note:
If the Stop statement is encountered in code that is running outside of the integrated development environment (IDE), the debugger is invoked. This is true regardless of whether the code was compiled in debug or retail mode.

This example uses the Stop statement to suspend execution for each iteration through the For...Next loop.

Dim i As Integer 
For i = 1 To 10
    Debug.WriteLine(i)
    ' Stop during each iteration and wait for user to resume. 
    Stop 
Next i
