I ve experimented with typing  exit for  a few times and noticed it worked and VB didn t yell at me  It s an option I guess but it just looked bad   I think the best option is similar to that shared by Tobias  Just put your code in a function and have it return when you want to break out of your loops  Looks cleaner too   For Each item In itemlist     For Each item1 In itemlist1         If item1   item Then             Return item1         End If     Next Next

Unfortunately  there s no exit two levels of for statement  but there are a few workarounds to do what you want    Goto  In general  using goto is considered to be bad practice  and rightfully so   but using goto solely for a forward jump out of structured control statements is usually considered to be OK  especially if the alternative is to have more complicated code   For Each item In itemList     For Each item1 In itemList1         If item1 Text    bla bla bla  Then             Goto end of for         End If     Next Next  end of for   Dummy outer block  Do     For Each item In itemList         For Each item1 In itemList1             If item1 Text    bla bla bla  Then                 Exit Do             End If         Next     Next Loop While False   or  Try     For Each item In itemlist         For Each item1 In itemlist1             If item1    bla bla bla  Then                 Exit Try             End If         Next     Next Finally End Try  Separate function  Put the loops inside a separate function  which can be exited with return  This might require you to pass a lot of parameters  though  depending on how many local variables you use inside the loop  An alternative would be to put the block into a multi-line lambda  since this will create a closure over the local variables  Boolean variable  This might make your code a bit less readable  depending on how many layers of nested loops you have   Dim done   False  For Each item In itemList     For Each item1 In itemList1         If item1 Text    bla bla bla  Then             done   True             Exit For         End If     Next     If done Then Exit For Next

If I want to exit a for-to loop  I just set the index beyond the limit       For i   1 To max         some code         if this i    25 Then i   max   1         some more code        Next    Poppa
