Hey!
Ok, I do have the return types in my actual code (so I redid it below).
But here's the thing: CGradient is defined AFTER CImage (both within CGraphicsSystem). Could this be why I'm getting the 2 errors:
error C2245: nonexistent function 'CGraphicsSystem::CImage::DrawRectGradient' specified as friend
error C2511: 'DrawRectGradient' : overloaded member function 'void (struct QGame::QGRECT &,class QGame::CGraphicsSystem::CGradien
t &)' not found in 'QGame::CGraphicsSystem::CImage'
c:\documents and settings\joel&sophia\my documents\computers\programming\vc++\libs\qgamelib\include\qggraph.hpp(199) : see declaration of 'CImage'
? The thing is, if I define it BEFORE, then I get an error for using CImage before it was defined (for the "friend CImage::..." line). (Or maybe you were talking about the actual class declarations before the definitions. Anyway, please help! Thanks) 
Here's again what I have
class CGraphicsSystem;
class CImage;
class CGradient;
class CGraphicsSystem
{
public:
class CImage
{
public:
... // public functions
void DrawRectGradient(RECT&, CGradient&);
};
class CGradient
{
... // public functions and protected member variables
friend void CImage::DrawRectGradient(RECT&, CGradient&);
};
};

You wrote: Or maybe you were talking about the actual class declarations before the definitions
Yes, indeed. If you like to keep this design, move the class CGradient; declaration to the public section of CGraphicsSystem.
However, I'd suggest NOT to embed image/gradient classes in CGraphicsSystem, to avoid complex constructions later. You'd better create a namespace, so you can write using namespace GraphicsSystem; in your .cpp files and make everything more readable.
You're welcome.

Hey, it worked to move the declarations into CGraphicsSystem! (guess you're not surprised.)
So far the architecure has worked fine. I'm just adding more features. But I'm curious, what are the "complex construction" situations you were talking about? Doesn't CGraphicsSystem simple contain CImage's and CGradients? (since it doesn't have to do with, for example, the CSoundSystem) Maybe my architecture has OO design problems?
Thanks again. Later.

Hi,
I tried pEdit->SetWindowText("/n"); but a junk character is displayed instead of going to new line .
Plz help.
|
|
|
|
|
Put "\r\n" instead of "\n"
Also be sure the edit control is multiline (has ES_MULTILINE style).

At some time in the past, Life was simple, we had telex machines, printing on rolls of paper! In those days, when at the end of a line, the next step was sinple, you send a signal to make the paper advance one line, a \NL symbol, and you followed it by a Carriage Return Symbol, a \CR Symbol! Then the CRT Screen was invented, and everyone took a step back. What shall we bo when we are at the end of a line: Send a NL, Send a CR, or send a totally new magic incantation. There was never any agreement on this issue, and it still seeps through into the WIN32 in unexpected ways. for instance, in opening files. By reason of history, if you open or save a Textfile, e.g. by using FILE f = fopen(!MyFile.txt","a+"), any New Line Char (\n) will actuallly be translated on the fly to a '\r\n' pair. When reading back, every '\r\n' pair will be converted on the fly to be read into memory as a '\n'. You may avoid this translation on the fly by opening your files as "a+b" (b for Binary). The purpose of the above is to explain that Microsoft maintains two text formats, The one used in a Program, and the One stored on File! This is all without good reason, but that's the way it is, anyways. The problem is, that Microsoft is not consistent in how the rule is applied! For some reason, best known to both God and Bill Gates, certain controls expect the '\r\n' pair, or in others the '\n\r' pair to work propperly. Try to replace each '\n' with an '\r\n' or an '\xa','\xd' pair. You may have to copy your strings into a buffer to do so, I've been doing so for a long time, Unfortunately, that's the only way it seems to work! By the way, Your resource NEEDS to be flagged as MULTILINE for any of the above to work!

Compiling resources...
Compiling...

Please tell me what else I have to do inorder to proceed with GDI+ with VC++ 6.0
Thanks

The redistributable is the package a user installs to use GDI+. You need the GDI+ SDK.

Hi,
If I select 'System menu' in the properties of Dialog box so that I can have Maximize and Minimise buttons on the top, an icon appears on the left corner of the window of the dialog box. Is there anyway I can remove or change this icon?
Thanks.

Thank you.
This is what I did:
HICON m_hIcon;
m_hIcon = AfxGetApp()->LoadIcon(IDI_ICON1);
SetIcon(m_hIcon,FALSE);

Hai
if u want to change system icon.
u load a icon . in ICON resource view.
and give that icon IDI_NAME.
HICON m_hIcon;
m_hIcon = AfxGetApp()->LoadIcon(IDI_NAME);
SetIcon(m_hIcon,FALSE);
Hi,
Thanks, if u think it's good.
otherwise sorry.
|
|

|

U can do it as follow:
SetClassLong(hWnd,
GCL_HICON,
(LONG)LoadIcon(GetModuleHandle(NULL),
MAKEINTRESOURCE(IDI_ICON__MAIN)));

Hello everyone!
OK, I have:
vector<Vehicle> vehicles;
Class Vehicle doesn't have a constructor. However, when I add a constructor, I get this error on the line in which vehicles is declared (see above):
1>c:\incoming\war game\Game.h(11) : error C2065: 'Vehicle' : undeclared identifier
The declaration of the constructor is as follows:
Vehicle(int x, int y, int id);
What is wrong with this code? Thanks!

If you don't add a constructor, the compiler automatically adds an emtpty one for you. Add an empty constructor to your class, and it should work.
|
|
|
|
|
That's the problem - if I add an (empty) constructor, it gives me the error...
It's error-free when I don't add one.

You must add a default constructor that doesn't need any parameters: Vehicle::Vehicle()

Look into GDI+.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.
