3 | 1 | Wil van Antwerpen | In recent versions of DataFlex you do not have to use the Self notation when addressing objects. |
4 | 1 | Wil van Antwerpen | |
5 | 1 | Wil van Antwerpen | Eg. |
6 | 1 | Wil van Antwerpen | ~~~ |
7 | 1 | Wil van Antwerpen | Get Value Of (oMyNewForm(Self)) to sValue |
8 | 1 | Wil van Antwerpen | ~~~ |
9 | 1 | Wil van Antwerpen | can be written as |
10 | 1 | Wil van Antwerpen | ~~~ |
11 | 1 | Wil van Antwerpen | Get Value Of oMyNewForm to sValue |
12 | 1 | Wil van Antwerpen | ~~~ |
13 | 1 | Wil van Antwerpen | |
14 | 1 | Wil van Antwerpen | The latter form is much easier to read for most human beings, so it is a preferred notation style. |
15 | 1 | Wil van Antwerpen | |
16 | 1 | Wil van Antwerpen | The refactoring option "Drop Self" helps you to find and rewrite all the object notations that use the legacy self style and suggests to change them into the variant without Self. Hence the name. |
17 | 1 | Wil van Antwerpen | |
18 | 1 | Wil van Antwerpen | The refactoring method will popup a message box that asks you if you want to change the line of code. |
19 | 1 | Wil van Antwerpen | In it's most bare form it does that for each change. |
20 | 1 | Wil van Antwerpen | |
21 | 1 | Wil van Antwerpen | As this is fairly invasive, you can tick a checkbox to remember specific objects. |
22 | 1 | Wil van Antwerpen | |
23 | 1 | Wil van Antwerpen | So if you already decided to rewrite (oMyNewForm(Self)) into oMyNewForm then it remember that particular choice. |
24 | 1 | Wil van Antwerpen | |
25 | 1 | Wil van Antwerpen | You can also keep the current lining out of the code by replacing the "wiped" out part of the code replaced with spaces. |

27 | 1 | Wil van Antwerpen | ## Why all the questions? |
28 | 1 | Wil van Antwerpen | |
29 | 1 | Wil van Antwerpen | The reason you get the message box is because our parser can not detect everything at this stage. |
30 | 1 | Wil van Antwerpen | |
31 | 1 | Wil van Antwerpen | For example if you are using a property to store a object id then the replacement would break your code. |
