According to this[^] it shouldn't.

Is there any typedef or any other kind of association with that word in the programm? Try to look for "small" in all files in your project. The compiler can complain about that use, but the cause could be in any other place.

The source code you provided compiles fine on 2010 (provided KLT_SMALL_DET and KLT_TRACKED are defined).
Are you sure there arent't spurious characters in your original source file?

You missed one of the bold-lines, the problem is not with KLT_SMALL_DET, it is with "small" variable name.

And the fact that you can compile that code snippet, is a kind of confirmation about my theory that "small" is maybe being defined in other place.

I missed nothing, of course. Poke tongue | ;-P

I copied the whole OP function and made it compilable by defining (with dummy values) KLT_SMALL_DET, KLT_TRACKED just to check if small could be the issue: it turned out that was not the case.

If you hover your mouse over the word small it shows #define small char, and Go To Definition takes you to line 153 in RpcNdr.h.

I've the variable

float hops;

causing a similar problem.
Could you please indicate the header file and the line number of the troubling #define?

Sorry, doesn't show up in my compilation unit. If you get the problem why can't you find its definition using the method above? Or are you not using Visual Studio?

Aaargh! you got me ... Laugh | :laugh:

I know this may look a little more than a little strange! But for a reason I want to write a whole function in a file at run-time. OK, let's do some clarification:

see you have a function like:

void foo ()
{
        your code ...
}

after compilation we have some thing like:

// foo()
 
push 210
mov eax, ebx
...

and in binary level:

// foo()

E8 00 DA 65 00 00 DF

What I need is to write these binary codes in a file.

Note

1- There's no such an instruction like mov eax, eip or pop eip in Intel instruction set. Actually there's no instruction to get or set eip directlt.

Thank you masters!

Why don't you get the compiler output?

because I need to write it anywhere I want. I don't want to use the simple copy-paste method.

The you have to write a compiler... Smile | :)

As I understand it, you want to include in your executable, a number of Datablocks which you want to use as prototype executable files, to be called by your process. This can be done, and I've done it. If that's what you want, it also requires No ASM Code to implement!

Hi,
I have a binary image with black background and a white object. I want to implement c++ codes that will detect when there is a hole in the object (black cell in the white object). I want to be able to know precisely the size of the hole and where it is located on the object.

Can someone give me any advice.
Thanks in advance,
Franck

One possibility could be using GetPixel ().

If you know the coordenates of that white shape, then you can just check in the shape if the pixels contained are white or black and increment a counter to know the area of the target object.

Regards.

Thanks for the answer,
Unfortunately, I do not know the coordinates of the white shape.

Franck

Then you are going to use the same to locate it first.

If the white object is with a random shape, and random coordinates I think you are going to check the whole image, and then process it.

You can get an approach of using a 2d array full with 0 (black) and 1 (white) to simbolize the image.

the main term you'll need to research is "blob detection and analysis".

it's a big and complicated subject, however.

maybe i can help you.

You will have to scan your image pixel by pixel. Getpixel() is one approach but is not very quick. The second approach is to get a pointer to the pixeldata. I'm not sure what you want to do with the results but one of the things you could do is to create a region (a clipping area) of those holes. Weaponed with that you could fill it or do everything you like. A region will not give you a direct insight of the size (because it may be a complex (non-rectangular) object) but -although unknown- holds a representation of the hole.

If you feel this approach will help you feel free to send me an email - I can give you an algorithm to create a region from a complex figure.

What is the nature of the binary image. It appears to describe a Picture. Now,Is it a Bmp (Bitmap), Is it a GIF File, what is it, or, is it just that, an image prior to capture(e.g. in your mind only).
What can open and display it as a File? Is it per chance encrypted?

None( Or maybe very few) of the contributers are clarevoyants. You want to be more specific before you can expect a reasonable answer. I suggest that a bout of reading may solve a lot.
