Re: what is "hooks or hooking" in the mfc

James R. Twine17-Apr-07 2:44

   Hooking in this sense means getting notification of specific window (creation, initialization, etc.) and being able to get access to (or intefere with) with the data associated with that event as well as being able to do additional processing.

   Look up the hook-related functions like SetWindowsHookEx(...) for more details. MSDN also had documentation on "Windows Hooks" that wil be useful to you.

   Peace!

So you are using CMenu class Isnt it?
If so you can set your ID to the menu item using
the second parameter of CMenu::AppendMenu()

refer the documentation in MSDN @ http://msdn2.microsoft.com/en-us/library/kb145b0a(VS.71).aspx[^]

The same case even if you are using Win32 methods.

Hi,

An easy way that I normally follow is to do the following:

In your header file you will find the following(more or less):

#ifdef PROJECT_EXPORTS
	#define PROJECT_API __declspec(dllexport)
#else
	#define PROJECT_API __declspec(dllimport)
#endif

Create a function prototype in header file:

PROJECT_API int myFunc(int a, int b);

Export your function in a .def file.

LIBRARY PROJECT
DESCRIPTION "Export Some Symbols."
EXPORTS
DllMain @1
myFunc @2

In your calling application, include the header file of your dll program and copy the .lib and .dll files (found in the debug directory) to the calling applications directory.
Link your calling application with the .lib file. (Project Properties -> Linker -> Input -> Additional Dependencies)
And call the function.

myfunc(2, 4);

Hope this helps Smile | :)

just wondering, why are you exposing your DllMain() function in your .def file ?
AFAIK, no one should call it explicitely (the system does it) so there's no need for any one to see its clear name (even the mangled name is not shown in normal cases i believe)

Use GetFocus() which returns the CWnd* object which currently has focus...

So you can compare likewise...

bool <code>CYourMainWindow</code>::IsFocussed()
{
   return GetFocus()->GetSafeHwnd() == this->GetSafeHwnd();
}

Don't compare CWnd* values to tell if they are the same window. Call GetSafeHwnd() on both and compare the HWNDs.

Hi all,

I want to know whether a function exists that can invoke a messagebox with a editbox inside of it (From a WIN32 console application / without using MFC)??
Makes sense ?

Thanks

Hi,
Better u add one more dialog with an edit box in it. Make it as a child, then you can use it just like MessageBox by calling the dialog in appropriate places.

CMyDialog *dlg = new CMyDialog();
dlg->Create(IDD_DIALOG1, NULL);
dlg->ShowWindow(SW_SHOW);

use this in places where you would like to call the MessageBox.

Regards,
Syam.

You'd have to use at least Win32 to get what you want.
