In the code below '(a.ptrToFun)()' function call gives syntax error where as '(a.*ptr)()' doesnot.
Can someone explain what the problem is?
class A
{
public:
void AFun(){ cout<<"A Fun"<<endl; }
void (A::*ptrToFun) ();
};
int main()
{
A a;
a.ptrToFun = a.AFun;
(a.ptrToFun)();
void (A::*ptr) ();
ptr = a.ptrToFun;
(a.*ptr)();
return 0;
}

Well, if you know the correct syntax, and you get the right functionality, then there isn't really any problem.
Pointers to member functions have complex syntax.
Feel proud you've mastered it, and move on.

Can you please give the right syntax and explain why it is so?
|

Didn't you already work out the correct syntax for yourself? You're better placed to help *me* now.

yes , I got the syntax. The syntax is (a.*(a.ptrfun))(). But i am not able to understand why this is so complex? If you have any explanation for this, kindly reply.

Let me have a try... 
(a.*(a.pF))()

(a.*ptr)() means "take the object a and the method pointed to by ptr, then call that method using a as this". The "use a as this" part is where the complexity comes from. You can't just call ptr() because you haven't said which object to use as this.

Right-click the file and select Properties.

Hi,
How can I select all item of ListView?
I used :
for(int i=0;i<ListCtrl.GetItemCount();i++)
ListCtrl.SetSelectionMark(i);
But it do not show the selection color.
|
|
|
|
|
Hi pther.
Try as below
ListCtrl.SetItemState(-1, LVIS_SELECTED, LVIS_SELECTED);
The -1 that is first parameter is meaning that all items is applied.
Bye.

I know cximage is a class for handling, um, images that is published in an article on this website.
Do you want to add a menu to the demo application that probably comes with that that article? Then you would add it in the same way you do to any other application.
If that is a struggle (and it was for all of us at some point), then use the appwizard to make a plain SDI app (or MDI), and see how it is different from the application you have.
Or ask on thr CXImage article page for more specific help.
Iain.
