CEvent( BOOL bInitiallyOwn = FALSE, BOOL bManualReset = FALSE, LPCTSTR lpszName = NULL, LPSECURITY_ATTRIBUTES lpsaAttribute = NULL );
this is the construtor of the CEvent , all are optional constructor, you need to set it the way you want it,
2nd parameter will be of some interest to you.

Agreed that the constructor helps me specify the same but how do i use the constructor in creating my object. Ok lets put it this way
class A {
CEvent e;
}
now how do i create e with the constructor.
I hope u r getting my problem

(Well i found answer to my first question it is automatic)

|

class A{
{
CEvent e(TRUE,TRUE,NULL,NULL);
}
this creats a event that is initialy owned, manual reset, unnamed event, null security.
Hope i cleared ur problem.

It gives syntax error on compilation
|
|
|
|
|
Class A
{
CEvent e;
A() : e(NULL,NULL,NULL)
{
}
};

hmm thats a inline definition...
i dont wanna create my class object in that fashion & neither does that compile.
My class A has its own constructor
|
|
|
|
|
That is the syntax for calling membervaribles ctors, put it
in your class A's ctor.

- I don't necessarily agree with everything I say
|
|

This is the scenario
class A {
A(int,ClassB *b);
CEvent e;
}
In the implementation file ->
A::A(int,ClassB *b) {
What do i put here?
}
|
|
|
|
|
A::A(int,ClassB *b) :
e(NULL,NULL)
{
}
The actual params to e above is wrong, pass them as you like to
have them.

Ok that solves my problem, thanks

thats solves my problem thanx

I am not absolutely sure, but I believe that in this construction call, a temporary CEvent object is created, then an equality operation is used to make the e equal to it, and then the temporary object is deleted.
On a memory-constrict system this might cause a problem. A better way when you have members in your class that are not base types (classes or similar) and need to initialize them, is to always use a pointer to the type, and reserve memory from the heap by calling new.

I dont think that is the case, any code in the ctor for the object would then be run twice.
Also if you had pointer members allocated in the ctor and deleted in the dtor they would be pointing to garbage.

After a quick check, the case was verified: the constructor of the member class is called only once if it is declared after the ':' on the host class's constructor.
However, I prefer pointers

}
How about this.

that doesnt work i have tried that
|

Well i guess that is the easiest way to initialise anything. Any way just out of curiousity what is the compiler error you are getting.
did you put the following statement.
#include <afxmt.h>

Yup i did that it gives some error
|
|
|
|
|
You still did not specify what error you are getting perhaps that would be more helpfull.

I have already got the asnwer to my problem from magnus & time doesnt permit me to do ne more on it

 Oops sorry didnt read that link... that is also a good answer.

if you use CEvent you us it with the follwing constructor. so you could set bManualRest = TRUE. it doesnt care if you use it as member of your class...
karo
---
CEvent( BOOL bInitiallyOwn = FALSE, BOOL bManualReset = FALSE, LPCTSTR lpszName = NULL, LPSECURITY_ATTRIBUTES lpsaAttribute = NULL );

ok guys,
im trying to build a simple dialog program using sockets, im gonna translate the code from a console program.
My problem is after creating a mfc dialog from the wizard.....my toolbar for adding buttons, menus, etc...is missing !!!
maybe im dumb....but after searching for ages i cannot find it...
cheers

Right click on the tool bar(while editing the dialog) to get the list of toolbars there you will find the controlbar.
select it.
