Vector of class with contractor

22-Jan-07 22:48

Hello,
I want to start a vector of calsses with the same contruct
Lets say this is my class :

<br />
class aaa<br />
{<br />
public:<br />
	aaa(int i){  m_iA = i;	}<br />
private:<br />
	int m_iA;<br />
};<br />

and I want now to do 5 classes with the same contruct:

<br />
aaa* f = aaa(2)[5];<br />

I have to do a loop for this (pointer of pointers etc.) ?
Or it is possible to do this somehow in a short way ?
Thanks,

In fact if you don't have a default constructor, the only way to do that is to have an array of pointers to your class:

aaa** pArray;
...
...
pArray = new aaa*[5];

And then loop through your array and create all the classes:

for (int i=0;i<5;i++)
   pArray[i] = new aaa(Value);

Of course, you will need to delete all these instances AND the array.

If a statically-allocated array is acceptable, you can do:

aaa stuff[] = { aaa(2), aaa(2), aaa(2), aaa(2), aaa(2) };

Hi,

I am using IADS component to query about the user information from a local machine.

Sometimes, When i call ADsGetObject method, it takes more time to query about the user. But some times it happens quick.

I am querying about an user who is created in the local machine.

What is the reason for this? How can i solve this problem.

Any help would be very much appreciated.

Thanks.

Hi,

There are two APIs for searching a folder
FindFirstFile & FindNextFile

or there is an MFC Class CFileFind, which is almost like a wrapper to above mentioned APIs. you can go through the documents of these APIs.

In the dialog editor, right-click on your listbox and search in the settings. There should be an option to sort the list. Uncheck the check box 'Sort'.

Mr satish,

I already told you that when you have to post code, you have to use the <pre></pre> tags around your pieces of code !

please edit your message consequently

ps: edit means reuse the same message and modifying it, without reposting a new message (have you noticed the little [Modify] link at the bottom of your post ?).
as we are on a forum, it also implies that you share with us on the boards, instead of mailing me your modifications...

CSpinCtrl increment by 0.01

Good day to you all!
I created an application having a spin control(vertical scrollbar) attached to an edit box. I needed the application to increment/decrement by 0.01 everytime the scrollbar is pressed. Later on I found out that the default increment is set to 1. What should I do so that the increment would be set to 0.01 and also the display in the edit box having two decimal places?

Thank you very much for the help and time!

Huh?

I've never seen a spin control or scrollbar implementation that used floating point.

Why not set the range to range*100 and anytime you display the position use position/100 ?
