Is there such a thing? In short, I need to hook a game that was written with DirectX...

Thanks

Don't shoot too high on your first attempt at a real game - don't attempt to write a Halo or a GTA:VC on your own as your first project - you will fail and get depressed Smile | :)

Aim for something simple like Tetris.

Try out different tools to see what you are comfortable with - try Flash for some 2D games, for example.

Learn a simple and clean language such as VB.NET or C# or Python to gain programming experience with relatively little pain (which you will want to do) without getting immediately bogged down an insanely complicated but powerful language like C++ (which a lot of games are currently written in).

Learn LISP as skills development. Because you learn how to program well just as much from "odd and obscure" languages as much as "normal and popular" ones.

Try stuff out - experiment with different approaches to solving a problem.

Develop good algorithm skills - know what the operating complexity/advantages/disadvantages of an algorithm are. Your game is going to be slow if you use a bubble sort to sort the Z-Order of some polygons because you didn't bother to learn quick sort or radix sort because it looked too complicated. Knuth's Art of Computer Programming series has a lot on these algorithms - which leads to the next point:

You'll need books. Lots of books. Books covering DirectX, C++, object oriented design, software testing, dealing with people on software teams (you did plan on working with others, right?), and probably books on VB.NET/C#/Python to help writing your toolsets with (level designers, scripting, etc - you want something quick, dirty and productive for these)

Don't be impatient. It takes years to become a talented and skilled developer.

Ask sensible, concise and thought-out questions in the appropriate forums (here and elsewhere). (Note, your question isn't one of them Big Grin | :-D

It's too broad in scope.)

BTW, I'm not a games developer, just a highly skilled "normal" developer.

Do you have any programming experience at all?

If you have none, then the first thing to do is learn a language. Start simple and learn the basics of your chosen language before even contemplating writing a game.

If you do have some coding experience then http://gamedev.net[^] is a good resource for learning about game development.

Is it possible to set a few check buttons to be defaultly true so that when a user opens an applcation those buttons are by default true??
if it is how can we do that??

Try calling
CButton::SetCheck() in OnInitDialog() of your dialog class.

There is no window style to set to get your checkboxes set initially.
e.g. No BS_CHECKEDALREADY.

But its not hard to do this for yourself. If you use classwizard / DDX_Check,
just make sure your m_bAlreadySet = TRUE in your dialog constructor.

Or check the box manually in your OnInitDialog routine.

The possibilities may not be endless, but they are pretty large.

can u please give me exact code if I use class wizard /DDX_check?
I tried to declare a variable called m_Alreadyset to my check button of type BOOL and set it to true in OninitDialog, but it didn't work.

Hi,
Setting the BOOL variable to TRUE will work only before! a call to DoDataEcxhange.
So you must set your variable to TRUE before the line CDialog::OnInitialUpdate();
or call UpdateData(false); at the end of your OnInitialUpdate-Routine.
You may also consider doing the assignment in your dialog's constructor.

You'll need a member variable mapped to each of the checkboxes. Then in OnInitDialog(), simply call the SetCheck() method of each member variable.

m_checkbox1.SetCheck(BST_CHECKED);
m_checkbox2.SetCheck(BST_UNCHECKED);
m_checkbox3.SetCheck(BST_CHECKED);
...

Some possibilities have already been given to you.

If you use classwizard, you can assign a member variable of type BOOL to a check box.
Doing this will fill in all the right code for you. As I remember (I don't touch CW
with a barge pole) you can even assign an initial value of 1 (TRUE) to it. If not,
all you have to do is find the line in the constructor which initialises the check
variable and change it to say = 1; or = TRUE; depending on taste.

If you want to do it the hard way, then the following code will help. Is assume you
have a check box of value IDC_CHECK1, and you are making a dialog class called CMyDlg.

In the header:

class CMyDlg : public CDialog
{
public:
    CMyDlg (....);
    ....
    BOOL m_bCheckValue;
    ....

protected:
    void DoDataExchange (CDataExchange *pDX);
    BOOL OnInitDialog ();
    ....
};

In the implementation file (eg. mydlg.cpp)

CMyDlg (...) : CDialog (....)
{
    ....
    m_bCheckValue = TRUE;
    ....
}

BOOL CMyDlg::OnInitDialog ()
{
    ....
    BOOL bReturn = CDialog::OnInitDialog ();
    ....
    return bReturn;
}

void CMyDlg::DoDataExchange (CDataExchange *pDX)
{
   CDialog::DoDataExchange (pDX); // Nothing actually happens here, but its good practice.
   ....
   DDX_Check (pDX, IDC_CHECK1, m_bCheckValue);
   ....
}

I put in the OnInitDialog just to remind you you need to call the base member to ensure DoDataExchange
gets called.

By putting the DDX_Check in, rather than just checking the box in OnInitDialog, we make sure that
the value is retrieved when you press OK, so you can find out whether the user cleared the check box
or not.

Iain.

Make sure the member variable for the checkbox is a control variable, not value...then you can use SetCheck()

If it is a member function, yes. For global functions you have to add the inline keyword.

It's not guaranteed to be inline. It depends on the compiler.

The MSDN doc's [^] give a list of cases where the compiler can't inline, even if you specify forceinline.

The two of note are :
- default debug builds
- virtual methods

In either case the compiler will generate a normal function call.

Hiding the main window while loading

Hi!

I've created an SDI application with MFC. I want to add a splash screen during the loading of my program, to hide the main frame while loading and show it when the application has finished starting.

In my App class InitInstance function, I've deleted the two following lines:

<br />
	m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);<br />
	m_pMainWnd->UpdateWindow();<br />

But my main frame is still visible. How to hide it while my application is starting?

Thks in advance!

you could call your splash screen before the main frame is displaed

you could place this at the start OnNewDocument() function

Hi guys
There is a limit in the number of controls in a dialog?
There is a way to pass this number?
I was making a copy apste until the paste had less controls than the copy, then I thought that it was a limit
Best regards
