What i'm looking for, is a macro which finds every occurrence of
certain string, and delete the text which follows it (in the same line)

for instance, given this text:

bla bla bla //this should be removed
bla bla bla //this should be removed
bla bla bla //this should be removed

After executing the macro, I'd want to have

bla bla bla
bla bla bla
bla bla bla

I tried with the following code, expecting that it would find "//"
every time this string is in the text, but it actually doesn't do the
job

  With ActiveDocument.Content.Find
       .ClearFormatting
       .Style = wdStyleHeading3
       .Text = "//"
        Do While .Execute(Forward:=True, Format:=True) = True
             MsgBox "se encontró //"
        Loop
 End With

I'm really new in VBA, so any tips would be apreciated

tnx - jm
