Re: Changing the font of a control ( CStatic )

Yeah, thanks, It figures ...

(ranting)
it's kind of weird that I have a CWnd object with the SetFont() method and I need to keep a local copy of the font ... why can't it copy the font instead of keeping a pointer to it.

   It allows only a single instance of the same font to be used with multiple controls, and you (the developer) maintain its lifetime, so there is no additional allocate-copy-deallocate overhead.

   I would not want to set the font for 20 controls on a non-modal dialog, then open a few copies of that dialog, and have MFC have a bunch of identical copies of a font being managed.

   Peace!

MSVCIRT error

I've tried to implement the MATLAB C++ Math Library using Riazi's article posted 28 May 2003. I get a link error 'cannot find the file "MSVCIRT.LIB". I've tried the recommended fix (/nodefaultlib "MVSCRT.LIB" and (/nodefaultlib "MVSCIRT.LIB") which yields more undefined symbols. I've also tried selecting multithreading and still get the error. Any suggestions would be appreciated.

If you tell us what some of the undefined symbols are, sometimes we can suggest which library to try linking with. What seems to be missing?

Hi Everybody,

I am doing a project in image processing using VC++, in which I have to find the intersecting points in a grid.
I tried many corner detection algorithms. Everything works fine with straight lines but not with skewed lines.

Please help me with some algorithm or code

Thanks in advance

I guess you'll have to take each pixel and verify if it has the same value as at least one from his neighbours.
Something like this:
[ 1 2 3 ]
[ 4 5 6 ]
[ 7 8 9 ]
Now you take pixel #5 and check his value with the ones from that matrix. if it's the same then it is a point of the line(composing the grid), if not then it don't belongs there.
Once you know where the grid lines starts it's easy to identify the intersecting points since you'll know the angle and everything.

Not sure what you mean by "third party" but CHtmlView is part of MFC.

Parser for C++

I need a parser for C++ that can be integrated in Visual C.
I've tried to make one using yacc and bison but it didn't work(didn't manage to do the file).
Can anyone help me? Do you know where I can find it? Do you have it?
Thank you.

As far as I know, Visual C == Visual C++ and already has a C++ parser. Or are you using some very old IDE?

not exacly... if you change your source files extension from CPP into C, the compiler will be restricted to a C compiler (not C++)...

True, but that still doesn't mean that you can call the whole IDE visual C instead of Visual C++... Anyway, in his own reply to his original post he says that he needs an analyser that gives him the structure of the program... I don't know if such a tool exists...

No,no, I need a parser. I think a parser knows which statement is an conditional one or not.

i am currently working on such a project (C++ parser), but as it is a personal goal, i don't work very fast on it.

however, the principle is simple, and based on the work exposed in my article VisualCalc.
