In C++ the only difference between struct and class is the default visibility of members. A constructor for a struct is defined just like a constructor for a class.
|
|
|
|
|
struct Stru_A{
char Name[30];
int Age;
}Stru_A, *pStru_A;
pStru_A foo = new Stru_A;
foo->Name(blah blah blah);
foo->Age(blah blah blah);

I believe this may be what you are looking for:
struct Stru_A
{
char Name[30];
int Age;
Stru_A::Stru_A()
{
Age = 0;
memset(Name,0,30);
}
}
Hope that helps.

Is the following way correct for inckuding a constructor in a struct
<br />
<br />
struct Stru_A{<br />
Stru_A(char Name[30], int Age) <br />
{<br />
<br />
strcpy(this->Name, Name);<br />
this->Age = Age;<br />
}<br />
char Name[30];<br />
int Age;<br />
<br />
}*pStru_A;<br />
<br />
<br />
pStru_A xyz = new Stru_A("ABC", 123);<br />
<br />

I believe for what you're trying to do, you'll need this (note there are two constructors here - one with no parameters and the one you are trying to use):
struct Stru_A{
char Name[30];
int Age;
Stru_A::Stru_A()
{
memset(Name, 0, 30);
Age = 0;
}
Stru_A::Stru_A(char* inName, int inAge)
{
memset(Name, 0, 30);
strncpy(Name, inName, 29);
Age = inAge;
}
}*pStru_A;
pStru_A xyz = new Stru_A("ABC", 123);
Note also that you should use strncpy to be sure the copy doesn't overwrite the 30 character size you have, and still leaves space for the null terminator.
Hope that helps.

You also will have to manually put that terminating NUL into the Name buffer - strncpy(...) will not place a terminating NUL if reaches the specified limit.

Actually, since I have a memset to put a zero in all elements, manually adding a terminating NULL is not required - you'll notice I only copied 29 characters into the buffer in my example.

Correct. I was speaking in the general case, because if strncpy(...) is going to be used in this particular constructor, it is going to be used elsewhere as well, and knowing the limitations of the function are still important.

A struct and a class are exactly the same, except for the default member access (public and private, respectively). So you can write a constructor for Stru_A just as you would if it were a class.

Hi,
I've got a combobox that I'm populating values in this order:
AlphaEntry
6020
Now, when the combobox displays, it reverses the value like this:
6020
AlphaEntry
What gives?
I should add, these names are the text filenames of binary files loaded at runtime. I'm NOT setting these values at design time.

You have to remove the CBS_SORT style (it is a default value, at design time).

Don't worry about...
Such moments happen to everybody and usually you expect to find things as you leave them.

there's a CComboBox style(CBS_SORT) option when creating the combobox, be certain that it's not there when you create it.

Actually it is the default on Visual Studio resource editor.

6 has an ASCII value of 54, while A has an ASCII value of 65. That's why 6020 precedes AlphaEntry.

Hi everyone,
does exist a event or something like this that informs that the Frame is now maximized.
Because during the Maximization of the Frame, more than one OnSize-Event occurs.
Now i need a indice that the maximization is over and i can perform my actions...
Does any one have an idea?
Big thanks for your help

have a look to GetWindowPlacement.
Hope that helps.

It has each times (3x) the same value (SW_SHOWMAXIMIZED)
nervertheless thanks
|
|
|
|

In a pinch, I would set a short (25ms or so) timer each time the OnSize/Maximize event fires, resetting it and recreating it for each event, and when the last event comes in, the timer will then fire.
Just a Q&D solution...
Peace!

I've also think about it, with a timer/delay
If it's really the last possibility, so i must realise it in this way.
So, thanks to you too

How do you discovered that OnSize happens many times?
I made an attempt on my dialog, seeing it (the handler wrote to log file its parameters) only once.

With breakpoints or Messagebox that report a "I'm in OnSize"
And if the debug pauses, i can see that the Size-Messages are coming from the system, not from a self-written function.
2 On-Size-Event of the Frame executes also a OnSize on the View
And a 3-time on the Frame ( without a OnSize on the view )
Each OnSize on the View, a grid will be redimensioned and rows added/removed relative to the height of
the view. Propably the Size-Messages are coming from the Grid.SetWindowPos
I'm the only person that programms on MFC at the office, so i must ask each question here 
And to change from Visual C# to MFC is a hard way where everybody has a lot of questions
I even don't know if my style of MFC-Programming is correct

This is wrong way to track messages. Use log as suggested in earlier reply.
