Hi,

I have my application in MFC which is working fine on Windows Operating system.
Now i want to run the same application on Macintosh. I want to know do i need to make changes in my
code.
If yes what all things needs to be changed.

Or it can work perfectly alright without making any changes.

Thanks In Advance.

Is it a console application using only standard C++ ? If yes, then the only thing you'll need to do is to recompile your application for MAC. Now if you are using things that are not cross-platform (like the MFC for instance), then you'll probably need to rewrite part (or everything) of your app. There are cross-platform GUI libraries like wxWidgets to do that.

Your application will NOT work at all, on Macintosh. MFC is built around the Win32 API, which means it is not portable to another operating system than Windows.

If you want your application to work on multiple operating systems, then you must write it in plain C++, which should not contain a lot of operating system specific code.

For UI, you can use one of those open source frameworks, such as VCF[^], qt[^], wxWidgets[^], or something similar. Mind that you will have to compile it separately to build the specific binaries for each platform that you would want to deploy the app on.

In your case, it is not "changes" that you will have to make to achieve cross-platform execution, you must re-write your entire app.

Start with a HTTP 1.0, the protocol is quite simple to implement (compared to HTTP 1.1).

two dimensional pointer array casting (C question)

Hello

,
I have defined a two dimensional array of type double in one of my MFC classes
in class 1:
double m_aCoefficients[10][20];
and now I want to make a pointer to this variable in another of my classes and assign address of this double array to that pointer.
so i have defined in class 2:
double* m_pCoefficients[10][20];
and in my CMyDoc Class I have tried this:
m_Class2.m_pCoefficients = (double*[10][20]) &m_Class1.m_aCoefficients;
but it gives error
Error 4 error C2440: 'type cast' : cannot convert from 'double (*)[10][20]' to 'double *[10][20]'

How can I resolve this?
thanks

Pointer declaration have highest priority for the compiler. As multiplication is before additiont. Example: 2*3+4=10. This is about language definition and how the compiler works. Dont know more. Cry | :((

you better
double* pCoefficients;

m_Class2.m_pCoefficients = (double*) &m_Class1.m_aCoefficients[0][0];

or "maybe": double[10][20]* Confused | :confused:

Here you should have

double (*m_pCoefficients)[20];

After this you can write

m_Class2.m_pCoefficients = m_Class1.m_aCoefficients;

I hope it helps..

Sandip.

A is not a string, it is an array of 100 CString objects.

What is the problem ? You need to assign it at a certain position in your array, something like:
A[10] = B;

Hi,

You may be mistaken about CString.
You can store a variable in CString object.

CString string = "Test String";

If you want to copy CString A to B;
Do CString A = "Test String";
CString B;

B = A;

Thats it..

The price of anything is the amount of life you exchange for it.

Thanks and Regards.
