The code looks correct but I find it to be slightly offensive to me sensibilities. Smile | :)

I'm just kidding. I usually make a function or method when I see a sequence of code repeated more than twice. Something like this is generic enough that I definitely would.

Of course, it's not your job to put this is into a function. That is an exercise for the reader. Wink | ;)

Nah, that's childish.
You've to set up a linear algebra library, with vectors and rotation matrices, properly overloading the multiplication operator. Of course that's an exercise for you. Poke tongue | ;-P

On my defence, I wouldn't write such code repetitions in my own software (well, maybe I do in quick and dirty junk programs), the goal there was being as explicit as possible (the OP had doubts on the steps to take)

When you asked this same question[^] yesterday, part of my reply said:

Look at the actual values you are passing to MoveToEx and LineTo.

Until you do that, I'm not interested in helping any more, and I don't think too many others will be either.

MoveToEx(pCellInfo->hDC,center.x-x1,center.y-y2,NULL); // Here i will find the new axis from the center axis
                                                       // i.e (center.x point - x1,center.y point-y2)
                                                       //so that i get the start point from where i can start to draw rectangle
LineTo(pCellInfo->hDC,center.x-x1,center.y+y1);        //From here i will draw the rectangle

I hope you got it,what i am trying to do.

If i am doing wrong,please let me know,

Thanks for your reply

When I said "look at the actual values", I didn't mean the expressions, I meant the actual values. In other words, either add some code to print out the values when you call the function or put a breakpoint on the call and inspect the values in your debugger. Then you should be able to figure out what is wrong and work back to where your problem is.

How to validate a file path

I am writing an application that requests a file path from a user so that the application can process supported files in that directory. It is a console application. I would like to know how I can validate the path entered by the user to make sure that the path exists. I am programming in the C language. Please help.

Thanks Niklas, I believe this function will do, but it seem to be a Windows specific function. Do we have any way around in the ANSI C standard? If there isn't I will use the function you showed me, it's just that I want to keep the use of Windows functions at minimum in this application.

Maybe _stat() from <sys/stat.h> checking if the st_mode member of the _stat struct is _S_ISDIR. I don't know how much standard that is though.

Which file paths are valid or invalid is determined by the operating system, not the programming language. What is valid for Windows may not be valid for others such as Unix, and vice versa.

If portability of your code is of prime importance, your best bet IMO would be to actually try and use the path, say by attempting to create a file in the given directory path.

When I create portable code, I define my own little virtual OS and have an OS.h file which has different sections for each of the platforms (operating system and compiler tools) I support; it is full of defines from my virtual OS to the actual one.

I agree attempting an operation isn't the ideal way to determine validity, however it may (or may not) come pretty close to what the OP wants, after all the user entered a path for some reason, so maybe trying whatever it is the app is supposed to do with the path right away is a good enough approach, and by definition it would be as portable as the rest of the app.

in addition to the help from Luc & Niklas, there are things like Apache APR http://apr.apache.org/[^] which may be of use if you are doing a lot of this. I like Luc's approach for small time - which is essentially the same, but just defining the functions you need, whereas APR is a bit more encompassing
