Hi did you able to solve the problem. It seems somehow type of T is being initialized to CImage but is not obvious with the code you posted. Can you share the how you define the class CImage.

I think the problem is that the compiler interprets that if there is an operator definition with a Cimage parameter, and then is an override with a template parameter, the basic parameter is a CImage, and it has no possibilities about reinterpret the parameter as a number.
For the moment I've took out the template, and declared the override with a size_t parameter. It's enough for me at the moment, I think, because this declarations could run with every kind of numeric params. Isn't it?
Thank you very much!

I tried to test this with a simple class with just two operators similar to yours. I works fine and I got no errors. So I am not sure where is the problem.

CImage class is using a CImage namespace. May it has something relative to the problem.

I'm developing an animated game on Win32.
my message-loop looks like this:
MSG msg;
ZeroMemory( &msg, sizeof(msg) );
while( msg.message!=WM_QUIT )
{
if( PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ) )
{
TranslateMessage( &msg );
DispatchMessage( &msg );
}
else
{
CPTWindowManager::GetInstance()->RenderAllGames();
}
}
I have noticed that takes 50% of the CPU.
I wonder if this 50% are "for real". If so, it is not desirable.
I tried to use GetMessage() but I don't know how to figure out the "idle" state when using GetMessage().
Note that the rendering stuff are relatively simple rendering and thus the time they take is unnoticeable.

No matter how long the "rendering stuff" is taking, you have a busy loop all the time: there's nowhere a 'pause' in the loop (sleep or wait for something...). But don't worry too much, that's usually how games are written: you want to achieve the best possible performance, so it's normal that you will eat up all remaining CPU time.
In your case it is probably taking 50% of the CPU because you have a dual-core, am I right ?

Yes I have a dual-core.
Also, I don't 'feel' the 50% slowing down my windows experience.
I have, however, saw a similar game that when run only eats several %.
Perhaps they did some scheme with the WM_PAINT messages - they cause the window to refersh, by InvalideRect() I guess, and render on the WM_PAINTs.
Sound like something I should try ?
Thanks

It depends which kind of game it is. For example, if it is something static (like solitaire, mine sweeper, ...) then you don't need to repaint the view dynamically. You can simply repaint the view when something changed.
So, I can't really answer your question, it depends of the kind of game you are trying to write.

Thanks.
It has dynamic rendering, to be specific, it plays series of pictures according to time (what might be called animation).
So it must repaint all the time.

I have 3 files:
1. main.exe
2. rar.exe (the console version of winrar)
3. test.rar
main.exe will call rar.exe to extract text.rar.
Now, I'd like to make ONE install file with the 3 files, any way?
The easier the better, thanks.

AFAIK, installer-making tools (they're making one file that deploys the project) take care of the compression themselves. Try finding such free tool and just read how to use it. Because what your trying to do in not unusual.
|

As already said to you by another CPian, the installers themselves take care of the compression part. You can try NSIS or Inno Setup.
Or, if there's a reason why you would want to do it the way you said, how are you going to ensure the presence of winrar at the target machine? Or, are you going to ship winrar as well? I think that is an overkill.

All right, I'll ship rar.exe(the console version, only one file).
Because this is a patch, it needs to find a right directory to install.

I wonder how lazy people have become just because they can get free help. You did not try something as simple as this before asking it on the internet:
LPCSTR str = "I'm the dumbest";
CString szStr = str;

I'm talking about YOU. How you are trying to generalize things by throwing around terms like 'people'! You do not belong to the list of 'people', because they follow the guidelines. And you are rude enough to come back and tell me not to offer anyone help. Thanks for the tip, but I ain't gonna stop it as I love it.
Converting an LPCSTR to a CString? Holy cow! You neither did know what an LPCSTR is, nor did you know what a CString is. You did not try ANYTHING from your side and you came down to ask for help. People like you play a primal role in spoiling India's name in the International arena.
FYI, I've marked your reply as abusive.

So, now you're taking the discussion out of its context and proving to be rude. I'm sorry, but I'm bringing more people here.

Don't you think this is bit childish. My attitude towards people like this is to simply ignore them. You can't educate people like these.
