You can do that with local superclassing.
Subclassing is where you replace the windowproc of a window or control after it is created.
Local Superclassing is where you register a new class in your process that has the same name as one of the controls that have already been defined. When windows attempts to create a new control that has been superclasses, it will look in the local class definitions before it looks in the global definitions.
Here is an example of the code that you can add to make it so that every time that you hit a key in the edit box, a beep will sound. You can make the changes to do what you need to do.
WNDPROC lpfnEditClassProc = NULL;
LRESULT CALLBACK LocalEdit_WndProc(HWND hwnd, UINT msg,
WPARAM wParam, LPARAM lParam)
{
if (msg == WM_CHAR ) {
MessageBeep(-1);
}
return CallWindowProc(lpfnEditClassProc, hwnd, msg, wParam, lParam);
}
BOOL CreateLocalEditClass()
{
WNDCLASS wc;
if ( lpfnEditClassProc == NULL ) {
GetClassInfo(NULL, "Edit", &wc);
lpfnEditClassProc = (WNDPROC) wc.lpfnWndProc;
wc.lpfnWndProc = LocalEdit_WndProc;
wc.lpszClassName = "Edit";
wc.hInstance = _hInstance;
if (!RegisterClass(&wc))
return FALSE;
return TRUE;
}
}
void DeleteLocalEditClass()
{
if ( lpfnEditClassProc != NULL ) {
UnregisterClass("Edit", _hInstance);
lpfnEditClassProc = NULL;
}
}
If you need to change every edit control in windows to do what you want, you can look into global superclassing, but this is generally not a good idea.

Oh!  New idea! I never thought of that before! But I really need to detect every edit-like controls to get the user selected text. I found that there are some many edit-like control with various class-name. Can I superclassing without specified a class-name? I wondered that. Hooking maybe the best way to do the tast. Thanks anyway!

There is two ways of learning. Diving in. And slowly learning the basics. "The best way?" oc cource learning all the basics is the best way, but ive created the 3rd way of learning, that is: Diving in while you are slowly learning.
In this case... I was wondering how do you make a window "The kind of window that MFC would make" I dont expect a complete tutorial thread response, maybe a link and a couple basic first steps "to get me in the right area"
Personaly i am getting dang tierd of the dos screen "not giving up, just need somthing to work on, in order for i can learn somthing new and exciting "
Thanks all!

If you have VC, then use a wizard to create either a Win32 application to see how it's done the old way ( and the way that MFC wraps for you ), or a new MFC application to see how MFC does it. I'd recommend starting with an MFC dialog based application, it's the simplest. New dialogs are added by creating them in the resource editor, double clicking on the dialog and following the prompts to create a class. Then you need simply create an instance of the class and call DoModal on it. It will return IDOK or IDCANCEL if you want to test for what your user did with it and any data not stored in controls will be there for you after it closes.

The cold swirl as touch to ice
Dark cavity, abyss, hollowness
A dim glow would seem suffice
Far to reach, away from me
Look about, my sorrow plea
Touch to love and warmth to feel
A pull a tug to laminate and heal
Pools of life that glimmer me
Desire of full in richest thee
Love in full, and warmth impart
Darkness fills and thralls my heart
Entrapped deep in nothingness
Dark Cavity, abyss, hollowness…

Seriously, you need first to set up linking and including MFC, you'll be much better off taking my advice and letting the wizard give you a project in which all that is done for you.

I think you're approaching the problem from the wrong angle. MFC is a framework, not just a library. This means that usually it creates main window for you. Your program supplies parts of code used to fill in the holes. So "The kind of window that MFC would make" is a frame window or dialog window, depending on type of application.
When I was learning MFC, I've found that skeleton applications generated by AppWizard were the best place to start. Also, you may find SCRIBBLE tutorial useful - no kidding here, it really shows most important MFC concepts.

Hi all I am relatively new to the doc/view universe.
I have a pointer to my view and was wondering how to change the size of the view using code. I guess I want the document frame resized not the view.
Thanks

If you're using CFormViews, then <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_mfc_CScrollView.3a3a.ResizeParentToFit.asp">CScrollView::ResizeParentToFit</a> might be what you're looking for.

If you resize your frame window, the view will also get resized in an SDI applicaion.

You can use CView::GetParentFrame() to get a pointer to the frame containing the view. Then you might be able to call SetWindowPos or MoveWindow on the frame, if it not maximised.

i think that should be like this:
pView->GetParentFrame()->SendWindowPos()

MFC Application
SDI
I have a wizard that is normally launched from the view class in a message handler, CMyView::OnWizard(). However, I want the wizard to launch automatically after the view has been initialized at startup, and after it is already showing on the screen. Placing a call to OnWizard() in the CMyView::OnInitialUpdate() handler causes the wizard to launch before the view is visible on the screen.
It seems like I should call CMyView::OnWizard() from CMyApp::InitInstance(), but I don't know how to get a pointer to the view object. Is this even the correct way to go about it?
Many thanks,
Jon Sagara

Try handling WM_WINDOWPOSCHANGED for your CMyView and launching the wizard the first time it gets called --this might work.

Ok, this is what I have come up with in the CMyApp::InitInstance() handler:
[EDIT: typo fixed]
CMyView *pView = (CMyView*)m_pMainWnd->GetActiveWindow();
pView->DoWizard();
DoWizard() is a public member function of the view class that I defined to wrap the protected OnWizard() function.
It works, but is it safe? Is there a better way?

Oh! I always thought that would return the frame window. Didn't think it returned a pointer to the view.

Yeah, that may be a problem. Do you know how I can get a pointer to the view object from CMyApp::InitInstance()? That's all that's really holding me back. I don't want to leave my code the way it is because it seems like a big hack.

I don't think you should even do all this from the CWinApp derived class.
Can you try this. From your CMyView::OnInitialUpdate() post a custom message, say WM_APP+1 to your CMyView. Tehn in the handler for that message, call your function.
This technique is used to hide modal dialogs. Because in the OnInitDialog if we hide the window, it won't be effective as the window is not shown yet. So we post a message and the message handler hides the window.
I didnt try this out and am too lazy to try it out now.
6:32 AM now. I am not in an active condition as you might expect 
But please could you try this out and let me know it it did work?
If it does not work, I apologize for the inconvenience caused...
