How to write regular expression in UE to implement this requirement?

Question

Now I have a large C++ project which is made up of about 1400k lines of code. Now I have a requirement: Add one line of code to each class which is derived from CDialog, CWnd or CListCtrl. It's impossible for me to do this manually. I think maybe UltraEdit regular expression can give me a hand, but I can't write related regular expression by myself.

Anybody can help me?

Here is the line of code to add:

virtual ULONG GetGestureStatus(CPoint ptTouch) { return 0;}

and here is my code structure(just for a illustration):

class CRibbonAddPlaceDialog : public CDialog
{
    DECLARE_DYNAMIC(CRibbonAddPlaceDialog)

public:
    CRibbonAddPlaceDialog();
    virtual ~CRibbonAddPlaceDialog();
    enum { IDD = IDD_RIBBON_ADDPLACE };

protected:
    virtual ULONG GetGestureStatus(CPoint ptTouch) { return 0;}//the line to add
    virtual void DoDataExchange(CDataExchange* pDX);
    DECLARE_MESSAGE_MAP()
    afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
    afx_msg void OnDestroy();
    virtual BOOL OnInitDialog();
    virtual BOOL OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo);
public:
    BOOL AddButton(CFX_WideString csTitle, AddPlaceButtonProc proc, void* pClientData, CFX_DIBitmap* pButtonImage);
public:

    CReader_RibbonFilePageManager* m_pRibbonFilePageMgr;
    CReader_RibbonStyle_Static*       m_pAddPlace;
    CReader_RibbonStyle_Static*       m_pAddPlaceTip;
    CTypedPtrArray<CPtrArray, buttondata*> m_arButtonData;
    CTypedPtrArray<CPtrArray, CBCGPButton*>m_arButton;

};

Then begin to learn regex. It's not hard at all. You may [begin here](http://www.regular-expressions.info/tutorial.html) or [here](http://regex.learncodethehardway.org/book/). — HamZa, Jul 17 '13 at 09:18

Assuming you want to place that line right after the opening {, try searching for (with Perl regexes turned on):

^(class\b.*\bC(?:Dialog|Wnd|ListCtrl).*\r?\n\{\r?\n)

and replace with

\1virtual ULONG GetGestureStatus(CPoint ptTouch) { return 0;}\r\n

You did check the "Perl regex" option? – Tim Pietzcker Jul 17 '13 at 09:31
yes, i did check the "Perl regex" option, and my UE version is: UltraEdit Professional Text/HEX Editor Version 18.10.0.1016. Am i missing something? – Triumphant Jul 17 '13 at 09:32

I just tried it in my version (19.00, though), and it works fine there...sure you didn't make a copy/paste error? – Tim Pietzcker Jul 17 '13 at 09:34
aha, it works fine now, i will accept your answer. you are so professional in regular expression! A superman! – Triumphant Jul 17 '13 at 09:38
I have another question, I can't find and replace those class which are padded with several tabs or backspaces. Can you help me again? – Triumphant Jul 18 '13 at 02:42

keep in mind, that it'll add the line after each time `protected:` appears in the file – levengli Jul 17 '13 at 09:40
