Make the dialog modeless.

OK. I have changed my dialog to modeless but how to interact between dialog and document. For example:
In dialog I have number in edit box and on click "add" button I want this number to be written in new line on document.

Thanks for any help.

Post a message to it. When the document receives the message, it can then notify the view (i.e., UpdateAllViews()) that it needs to render the new data.

OK.
But can you give an example?
like:
when clicked add on dialog write "hello" on document
Thanks for help.

Assuming the dialog is modeless, call PostMessage() with some user-defined message and a pointer to some heap-based data (i.e., new) as the LPARAM. Provide a handler for that message in the document class. In that handler, update the document's data with the contents of LPARAM. Then call UpdateAllViews(). In the view' OnUpdate() method, it will get the latest data from the document and render it.

Aside from the dialog, all the rest is just plain MFC stuff.

You can test most of this by creating a sample SDI application. Add a CString member variable to the document and assign it some value. In the view's OnUpdate() method, get access to the document's data by calling GetDocument() plus whatever name you gave the member variable. Now render that data using the supplied DC's TextOut() method.

Hi
I have a great idea for a new virtual world which will be written in C++ and was wondering if someone would like to help with this project which I might need help with. It's a great design and should be easy to program. Members will be able to create a character, purchase and build houses, go shopping, chat with friends and much more in 3D.

Thanks

Andrew

A "great idea" is one thing, implementing it is another.

You're probably looking at 5 man-years work just to get a basic, reliable system up and running, and well over 20 man-years for a fully-featured, immersive system. Even something as crude as Second Life has had a huge amount of development time spent on it (and most people would expect much higher quality in any new offerings).

Rather than trying to built this from scratch yourself, you might try looking for a job at one of the companies already developing in this area.

I will get there, but it will take time. I have carefully planned out of how it will work and overall it should be easy to implement into C++. I am looking for someone to help me put in the basics like full screen, mousecursor, background music, sounds, graphics ect. Then I will think of a way to complete it whilst in the actuall world code.

If you are interested I would be delighted if you could help me with just the basics and I will be really happy with that so the project has been lifted off the ground.

Thanks

Honestly Andrew, I think you're seriously underestimating the scale of what you're planning. I'm not trying to put a damper on your dream, or say it's impossible, but as a game developer I have first-hand experience of this sort of thing. I've been involved in quite a few different projects over the years, from the small "3 or 4 person for a year" size up to the "nearly 100 for nearly 5 years" scale, and what you're proposing is definitely at the higher end of that range.

One suggestion I can make, which should help you along the way, and maybe get you producing games on a smaller scale first, is to look at some of the middleware and games engines out there. Try downloading a few, building some basic games, and getting a feel for the process.

A good place to start is with Microsoft's XNA framework, which gives you just about everything you need to get up and running.

There are also lists of engines at Devmaster and on Wikipedia - there are a lot to choose from, so I'd suggest trying maybe Ogre and Irrlicht as two pretty well developed ones.

If you really want to get into games development then it might be worth looking for companies in your area, asking what vacancies they have, or possibly even asking for a studio tour to get an idea of what working in games is like (it's not as glamorous or "fun" as people imagine).

Good luck with the project if you do decide to go ahead with it, but, as you say, it will take time, so be prepared to spend several years on it.

It isnt a virtual world like Second Life as advanced than that, I mean just like World of Kaneva on that sort of edge no higher than that.

As I said previously I am still looking for anyone who is interested, and that this project can be finished progressivly and I have planned out this project carefully step by step.

I hadn't come across Kaneva before, but it looks just about as complex as Second Life, and with higher quality graphics. Developing something like that is definitely going to be a pretty big job.

You'll definitely need to put together a fairly big team to do this, even using middleware. You're going to need coders, artists, designers, audio people, networking specialists... The list is pretty long. There are a few online boards where you can ask for people interested in collaborative work, although there are always more people with ideas needing teams than there are people interested in joining them.

I notice that Kaneva have made their engine freely available for non-commercial use (here) so it might be a good idea to check it out and see if you can use it to get your basic system up and running.

And in case you think I'm being too negative, have a look at what my company's currently working on. OK, maybe a bit more complex, and a bit bigger in scale, but in many ways a very similar exercise. You'd be staggered if I told you (that's if I was allowed to tell you) how many people are in the team and how long it's been in development...

See if I don't create a virtual world but redesign the project into being more game based in some ways but still allow players to upload music, videos, photos, ect to the game, would you able to help me as I think you are the best person to work with and I had a look at your website and was stunned at the work you do.

Thanks

Hi Andrew,

Unfortunately my company has strict rules about what we can work on as "outside projects" and something like this certainly wouldn't be allowed. I doubt I'd have the time to put into it anyway, as I prefer to spend most of my non-work time in non-programming activities.

Hopefully the links I've posted in previous messages will be of some use to you, and I'd recommend trying e.g. XNA to get a feel for the process of building a game.

re RTW and APB, well, it is pretty amazing, but I'm not actually on that project. I'm working on the game that's coming after APB - which will be even more amazing - obviously Smile | :)

Pretty much all my contacts are in the games business as well, so would probably be in the same position and unable to help you.

There are some online boards and lists where you can put up a message asking if anyone's interested in your idea, one of the more likely possibilities being GameDev.Net. Actually, GameDev.Net is a pretty good resource for learning about all aspects of game development as well, so you can probably pick up quite a lot of useful information by browsing through the articles and tutorials there.

Anyway, good luck with the project, and I hope you can get a few people interested.

View with Larger Dimension

I have an SDI based application, and is uploading a bitmap having dimension 1280*1280... The size of client area is less and the bitmap size is large... It only uploads the portion of bitmap that fits into the client area.

So how I may increase the client area, so that scroll bar horizontal/vertical appears and bitmap loaded properly. I changed the structure CREATESTRUCT in PreCreateWindow(CREATESTRUCT& cs)

but it did not work.

any idea? THANKS

The new Office2007 Ribbonbar - Are there pushlike checkboxes for it?

sashoalm5-Aug-09 2:01

I need a control for the new ribbon bar that looks like a button but behaves like a checkbox (i.e. a pushlike checkbox). In VC6 I could do that with the BS_AUTOCHECKBOX|BS_PUSHLIKE styles, but I can't find a ribbon button with the same behavior, and the new CMFCRibbonButton and CMFCRibbonCheckBox aren't real windows (they don't have hwnds), so I can't just add the styles.

There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

disabling finish button on property sheet wizard

Hi
Can anyone tell me how i can disable the finish button on a property sheet wizard ?

on my property page i initally define the buttons like

BOOL CPage::OnSetActive()
{
	CWizard* pParent = (CWizard*)GetParent();
	ASSERT_KINDOF(CWizard, pParent);
	pParent->SetWizardButtons(PSWIZB_BACK | PSWIZB_FINISH);

	return CPropertyPage::OnSetActive();
}

I then want to disable the finish button until a certain task has completed

i.e

void CPage::OnBnClickedBstart()
{
   GetDlgItem(ID_WIZFINISH)->EnableWindow(FALSE);
   DoSomething();
GetDlgItem(ID_WIZFINISH)->EnableWindow(TRUE);
 
}

i have also tried adding

CWnd *pWnd = GetDlgItem (ID_WIZFINISH);
    pWnd->EnableWindow(FALSE);

but get the same problem

Can anyone help at all

thanks

Simon

Compiler error when defining enum for registry

sunny_vc4-Aug-09 23:53

Hi,
I am using one of the registy class given in CP.
The keys are defined in .h file like:

enum Keys
	{
		classesRoot =  HKEY_CLASSES_ROOT,
		currentUser =  HKEY_CURRENT_USER,
		localMachine = HKEY_LOCAL_MACHINE,
		currentConfig = HKEY_CURRENT_CONFIG,
		users = HKEY_USERS,
		performanceData = HKEY_PERFORMANCE_DATA,	 
		dynData = HKEY_DYN_DATA						 
	};

When I compile this in VC6.0 it compiles with no errors.
But when I compile the same in visual studio 2003 it gives error like:" Constant expression is not intergral"
If i cast like: "classesRoot=(int)HKEY_CLASSES_ROOT", it throws warning such as "pointer truncation from HEKY to int".
How can I avoid the error.Please suggest.

Regards,
Sunil Kumar

Try converting to ULONG_PTR or maybe LONG_PTR instead of int, althorough making an enum out of HKEYs seems to be a tiny-bit ugly to me, but this might just be my personal taste. Good luck.
