You can either specify an ON_COMMAND_RANGE handler for all of them at once, or add buttons in the resource editor with the desired id, create handlers and them remove the buttons (but not the handlers, of course)

ok thank you!
But what I wanted to know is how to create buttons at runtime.
so the problem is that I cannot set ON_COMMAND_RANGE handler cause I don't know how many buttons there will be. But every button should react the same way!
greets

You can use ON_COMMAND_RANGE anyway, just allow for the max number of buttons.

Hi,
I am Aravind from Chennai.
I saw your comment at code project.com on Volume shadow copy.
I need some information regarding that. Hope you have ideas regarding that. If possible, can you please share them with me? My need is as follows...
I want to take backup of files using volume shadow copy service [VSS] in Windows 2003 server.
I have to use VSS for getting the file difference with their previous versions. So, I have to get the snapshot details from VSS.
So, how to get those details and where those snapshots where stored?
Thanks in advance.
Cheers by,

Hi,

I create a dialog box, which contains three-command button.
OK, Cancel and Apply. Then I place Tab Control on this dialog box. Tab control contains three pages like page1, page2 and page3. Page1 contains three-radio button namely Radio1, Radio2 and Radio3.Now I would like to do operations on Radio Button.
If I select Radio1, Apply button should be enabled the clicking on the Apply Button, It should be disabled. Similarly on Radio button2 and Radio button3. I know how to Enable/Disable Apply button-
CButton but;
but.Attach(GetDlgItem(IDC_APPLY)->GetSafeHwnd());
but.EnableWindow(FALSE);
but.Detach();

hello friends
how can i deny the list control column resizing when we double click the header control???
mind is everything.
|
|
|
|
|

Cohen , THANKS FOR YOUR RESPONSE
IN THAT ARTICLE THEY SAYS
The header control in the ListView control sends notification to the parent window (e.i. the ListView) before it begins resizing a column. We can override the OnNotify() function in the CListCtrl derived class to handle this notification. The code below prevents resizing of all columns. Note that the resize cursor still shows up.
BOOL CMyListCtrl::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
switch (((NMHDR*)lParam)->code)
{
case HDN_BEGINTRACKW:
case HDN_BEGINTRACKA:
*pResult = TRUE; // disable tracking
return TRUE; // Processed message
}
return CListCtrl::OnNotify(wParam, lParam, pResult);
}
BUT DIDNT WORK WITH MY LIST CONTROL....
ANY IDEA ??????????
mind is everything.

What do you mean by: "without any source(jpg,gif)lost"?
Do you want to put the jpg's in the same file?
For the HTML it would be easy... open byte mode read a html file write it to your file, read another and add it to your other file... It would be good if you put some kind of seperator between those html's such as ~seperator~ . For the jpg or other sources you can add them in the same way but you have to write somewhere in your file (The top would be good) the filename,etc...
For the file format I have no information... I think you have to write your extension into the registry and specify the application for it...
Well... I am a beginner ...

Hi
Provided that I have a class declaration as follows:
class A
{
...
}
and a class object a1:
A a1;
I want to know the difference between the following:
A a2 = a1; (1)
A a2(a1); (2)
A a2 = A(); (3)
A a2(A()); (4)
What is the most preferred? My colleague says that (1) and (2) are equal, since (1) will call the copy contructor automatically and operator= will not be called, is that true?
Thanks!

When class A has a copy constructor, these lines:
A a2 = a1;
A a2(a1); mean the same thing. The first line does not call operator= (this is a misconception I see posted occasionally). Likewise, lines 3 and 4 construct a new A object then use the copy constructor to copy it into a2.

Hi
Thanks for the reply. I have one more question regarding the copy constructor though:
If I'm not wrong, the = operator usually returns an object (in this case, it returns A& [or const A&? or const A? or A?, I'm not sure here, any help will be appreciated]), but since the copy constructor does not return anything, does this mean that the = operator in this case will not return anything also?
Thanks!

As I said, that is a constructor call in disguise, it doesn't call operator=. The reasoning is that in C you write:
int x = 1; but in C++ the original syntax was the constructor-call one:
A a1;
A a2(a1); So to make the two congruent, C++ also added these:
int x(1);
A a2 = a1; which both initialize a variable. For C++ objects this calls an available constructor with one parameter. If you want to call a constructor with more parameters, you have to use the a2(a1) style of syntax.

Hmm, I could have sworn Meyers explicitly states that not to be the case. However, testing shows you to be correct on your first point but not the second. All four variations result in the same thing.
When I get into work, I will check Meyer's book.
