Hello,
Im trying to write an applicatn which would draw upon a fullscreen game some text (a simple in-game text), and I came across the information I should hook up Direct3D functions and this is what I did using an example (hooking up CreateDirect9Device), but this function is executed only once at the beginning, and I am wondering which function should I hook so that I would be able to draw the text inside a already running game ? (And then how can I write the text ? with what commands ?)
Its very important to me, and I would appreciate any help in that.
Regards,
Pawel

Well, you can use Direct3D to draw 2D or 3D text to the screen in a game. Once you have the Direct3D device pointer you can call methods on it. So, you just need to do some research on the Direct3D API to figure out which functions you need to accomplish your task.

thx I found the answer. // IDirect3D::PResent and Flip

Is it possible to use the mouse scroll wheel to scroll up and down a menu in a console application instead of using the keyboard to select a menu choice. If possible, how do I do this?
Thanks,
Kristian

You could try trapping the mouses wheel message in your message loop, check if a menu is open, then set the item.

Using VS2005:
So there I am happily coding along, using classes that I wrote 6 years ago. The class in question has the following general content:
class CMyClass
{
public:
CMyClass(CString sFileName);
CMyClass();
virtual ~CMyClass();
...
};
I didn't feel like dealing with pointers, so I defined this:
class CMyOtherClass
{
CMyClass m_myClass;
...
};
The compiler is complaining that there's no default constructor for CMyClass, but there is (the bodies of both constructors are in the CPP file).
What am I missing?

dont you have to put almost like a 'forward definition' for CMyClass before CMyOtherClass ?
(sorry John, I cant remember the syntax - its simple and I should be able to ...)
ok - found this - it may be what I was thinking of

look for "Forward Declarations"

I can see no problem with your code - can you post more of it?

John, you're getting lazy.
I did a test compile of the code you gave and it compiles fine.
I hate to say it but it looks like there is something else you forgot to post.
If CMyOtherClass didn't have a constructor (and CMyClass::CMyClass() wasn't defined) then you would get 'no default constructor for CMyOtherClass' (even though it's CMyClass w/o default constructor).
So, i assume CMyOtherClass has a defined constructor.
If CMyClass::CMyClass() didn't exist in .cpp (and CMyClass() is in header) then you'd get a link error - 'unresolved external CMyClass::CMyClass()'.
If CMyClass() not in header, but CMyClass::CMyClass() in .cpp then you'd get your error 'no default constructor for CMyClass' but you'd also get 'CMyClass::CMyClass() overloaded function not found in CMyClass'.
The only case where you _only_ get the error 'no default constructor for CMyClass' is when CMyClass() isn't in either the .h or .cpp files.

hi Everybody,
I have been doing an application in which i have splitted the window into Two panes .By selecting the buttons in first pane,we can change the views in the second pane.Now My doubt is i have added buttons with icon's and color in both the panes of the splitter window.First as we run the application dy default some view will be there in the second pane.If we change the views of the second pane by selecting different buttons in the first pane,views will change ,but the color and icon of the buttons are being lost in the second pane.Can any body help me in this problem so that if we change the views also the Buttoon's color and icon does not loose.
Thanks in advance,
Radhika.

Hello everyone,
When using dir command to list all the files in a directory, for example, here is an output,
--------------------
C:\temp\test>dir
Volume in drive C is C
Volume Serial Number is CC95-21FF
Directory of C:\temp\test
2006-08-26 16:47 .
2006-08-26 16:47 ..
2006-08-26 16:47 0 foo.txt
2006-08-26 16:47 0 goo.txt
2 File(s) 0 bytes
2 Dir(s) 3,082,964,992 bytes free
--------------------
What I want to get are, foo and goo (files ends with .txt). I know how to do this in a programming way, parsing and parsing ... 
Could anyone have any ways which does not need programming, for example, by using some Windows commands (does there are any commmad like grep or cut on Linux)?
thanks in advance,
George

If you want to find files from your code use CFileFind
else...install unixutils and you'll have ls and grep (and lots of other usefull things)
|
|

Thank you eusto!
I think using CFileFind is a programming way, right? But I am looking for a way which is simply enough without any programming efforts.
unixutils makes senses. I will study it. Thank you again!
regards,
George

Yes, I am using a utility which ports grep like UNIX commands to Windows. Seems that Windows built-in commands do not have such rich functions.

I ahve a created a client server application useing TCP.
and another application useing UDP (methods: SendTO(),ReceivedFrom()),
in both applications the data will send to teh server and server receives the data. But i havent found a much difference by changeing the protocals.
programetically what is the diff betweem UDP&TCP?

Hello Ramanand,

Actually programetically not much more difference.
The difference is releted to use of bandwidth, multicasting, reliablity of data send/receive & other.

i heard that UDp wont give the aknoldgements for sending the data.
does it right?

In UDP there is no need to give ACK. so it is not reliable.
That's why udp take less bandwith for realtime transmission.
& It's easy to send multicast data via udp.

The biggest difference is that TCP/IP provides guaranteed delivery of messages in a specific order. UDP does not; messages can be fail to be delivered, or delivered out of order.
Software Zen: delete this;

|

UDP is a connectionless protocol which means is doesn't maintain a connection between sender and receiver. I believe with UDP packet delivery isn't guaranteed and the packets are not even guaranteed to be received in the same order sent. It consumes fewer resources however. I'm not an expert in this field however. I'd recommend doing some reading.
