Did it work?

No you couldn't - should use ON_COMMAND(ID_OK, my_ok_response) to process that.

use ON_MESSAGE(WM_CLOSE, myCustomCloser) where myCustomCloser has the signature
LRESULT myCustomCloser(WPARAM, LPARAM);
in your window class.

So ON_MESSAGE is for Windows system messages whereas ON_COMMAND is for anyhting thats WM_USER + .....

Yes

No - if you look at the definition of the ON_COMMAND macro, you'll see this:
#define ON_COMMAND(id, memberFxn) \
{ WM_COMMAND, CN_COMMAND, (WORD)id, (WORD)id, AfxSigCmd_v, \
static_cast<AFX_PMSG> (memberFxn) },
What this means is that ON_COMMAND handles the WM_COMMAND[^] message, which (to quote that page) is sent when the user selects a command item from a menu, when a control sends a notification message to its parent window, or when an accelerator keystroke is translated.

You may find sample code in the RegQueryValueEx documentation page [^].

Yes, there's a useful sample on that page, if you're interested in getting a data object with an unknown size. But if you want to read a C string and convert that string to a CString, you are probably better off with this:
<br />
BOOL ReadStringFromMysterioiusOSSource(char* destination, int maxChar);<br />
<br />
<br />
CString myValue;<br />
char buf[438];<br />
ReadStringFromMysterioiusOSSource(buf, 438);<br />
myValue = buf;<br />
(If you really need to use a OS function, just use the CString's assignment operator)

hi folks, yesterday i was not clear on my doubt. Sorry about that.
Here is my doubt:
i have a propertysheet which has three propertypages.Out of the three, one propertypage will contain the other two propertypages inside it.
click the link for Sample Application:
http://www.codeguru.com/cpp/controls/propertysheet/article.php/c595/[^]
If i insert a radio button in the third propertypage (which has two propertypages inside it), the application got struck. how can i resolve it?
thanks,
rakesh

With so little information, nobody will be able to help you.
Have you ever used a debugger? Visual Studio has one built in!

Are you a real person, or is this some new fangled kind of Turing test?

When your program "gets stuck", use the PAUSE icon on visual studio to see where the program execution is in your code. YOu can then use the "Step into", "Step Over" and "Step out" methods to see what your proggie is doing.
Also, check the following: your first radio button in your radio button group should have the WS_GROUP style on it, also, the next control in the tab order that comes right after the last radio button in the group should also have the WS_GROUP style. If your property pages are created from dialog resources made in visual studio's dialog editor, make sure that they have the "Control Parent" and "Control" styles set.
Do any of these help?

int f1(int i, int j);
int f2(int i, int j);
int (*fptr)(int,int);
};
Test.cpp
-----------------
int Test::f1(int i, int j)
{
int res = i+j;
cout<<"IM IN f1 : Reult "<<res<<endl;
return res;
}
int Test::f2(int i, int j)
{
int res = i-j;
cout<<"IM IN f2 : Reult "<<res<<endl;
return res;
}
main.cpp
------------
int main()
{
Test obj;
int (*fptr)(int,int) ;
fptr = &(Test::f1);
fptr(2,1);
return 0;
}
Actually im getting error in fptr = &(Test::f1); line
i.e Error 1 error C2440: '=' : cannot convert from 'int (__thiscall Test::* )(int,int)' to 'int (__cdecl *)(int,int)' c:\documents and settings\e_skanun\my documents\visual studio 2005\projects\test\test\main.cpp 35
And im nt able to correct.
plz do help.

Global functions and class member functions do not have the same signature: for a function member of a class, the this pointer is passed implicitely to identify the instance of the class on which the function is called.
What you are trying to do there is store a pointer to a member function in a pointer to a global function. So, that's why the compiler complains that you cannot do that.
EDIT: oops, I misread your code sorry. David's answer is correct.
