MS used to sell a cross-platform compiler for the MAC that allowed MFC apps to be compiled for the MacIntosh platform. Last version I think was Visual C++ 4.2 (or 4.0?). Has anyone ported a MFC app to Mac OS 9 or X? Is anyone still using VC++ 4.X for Mac? My app is fairly simple, although it does rely on the IE IWebBrowser2 component for some functionality.
I would love to hear anyone's (recent) experiences of trying to get an MFC app ported to the Mac, which seems to be making a comeback of sorts...
Thanks!

The last time I did this was in 1997-98 using the VC Cross compiler. Not sure which version of Mac OS but it certainly wasn't OS 9 or X. It wasn't easy as there are lots of UI difference that made things difficult.
I don't think MS support the cross-platform compiler anymore. Your best bet is to look at something like CodeWarrior but don't expect MFC compatability.

You can either use the Shell_NotifyIcon API call or you can use Chris Maunder's class! The first one is easier as it involves just that one call. The 2nd one is a lot more powerful, because Chris has thrown just about every feature you can think of into his little class.

What I mean by this subject is that I need to be able to open a text file, read it's information in, convert it to raw binary information ( ex. "this is a test" = 10110110 ) and then save that information out to a new file. I am unsure of the code ro do the actuall ASCII to Binary Conversion. If anyone has code to do this under straight WIN32 API I would be very grateful.

Never heard of a Win32 API that will do what you want. You'll have to write the function yourself by converting each character.

I know there isn't a function in win32 API that can do this transparently, which is why I was asking here about how to do the actual CONVERSION as I don't know how to do it.

There are at least two ways I know of to convert a number to its binary value, like the windows calculator does.
(1) Set up a bit structure and access each of its members just like any other structure.
typedef union
{
struct bits
{
unsigned short bit1:1;
unsigned short bit2:1;
// etc.
} bits;
unsigned short theNumber;
}BITS;
BITS b.theNumber = 365;
int bit1 = b.bits.bit1;
(2) A much more efficient way is to compute the bit pattern using the >> operator. If you look at the assembly code produced by the compiler from the method shown above, you will see that it actually uses the right shift operator to get the value out of the structure.
int x = 365;
for(int i = 1; i <= 16; i++)
{
int n = (x >> i) & 1;
printf("%d\n", n);
}

Have a look at std::bitset and its to_string.

would I be able to take a string using one of the above methods and use this kind of progression on it? See Below:
string > individual characters > binary value > string?
the reason why i want to get a string of binary values is so that I can run an rle algorithem on the resultant string and compress it down REALLY tight. I figure I'm more likely to get a really long run with rle if I'm dealing with either a 1 or 0 bit value as opposed to hex, octal, etc.

And you expect to get a "REALLY tight" compression using this? Make it easy on yourself and have a look at zlib or LZO.

Ok I know this is kinda simple, but why doesn't this produce a linefeed (or carrage return) ?
CFile cFoo;
cFoo.Open("bar.txt",CFile::modeCreate | CFile::modeWrite );
{
cFoo.Write(_T("TEST\n"), 5);
cFoo.Write(_T("TEST2\n"),6);
cFoo.Write("TEST3\n",6);
}
cFoo.Close();
Thanks

Maybe you need to add the \r carrage return?
cFoo.Write(_T("TEST\n\r"), 6);
Does that work??

Hey Colin
I just noticed when you open the file the option CFile::typeText is not specified.
MSDN:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_mfc_cfile.3a3a.write.asp
Also:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_mfc_cfile.3a3a.cfile.asp
"CFile::typeText Sets text mode with special processing for carriage return–linefeed pairs (used in derived classes only)."
You should get your carrage returns then. Also carrage return\linefeed is counted as one character. Hope I helped.

Because a "newline" in DOS/Windows is "\r\n" not just "\n". FYI, if you use CStdioFile::WriteString(), it converts "\n" to "\r\n" on the fly.

I have
void CMainFrame::SaveOptions2()
{
CRect rc2;
GetWindowRect(&rc2);
HKEY key;
DWORD size, type, disposition;
if (RegOpenKeyEx( HKEY_CURRENT_USER,APPLICATION_KEY,0,
KEY_WRITE,&key)!=ERROR_SUCCESS)
{
RegCreateKeyEx(HKEY_CURRENT_USER,APPLICATION_KEY,0,"",
REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS,NULL,
&key,&disposition);
}
// int
type = REG_DWORD;
size = 4;
m_height = rc2.Height();
RegSetValueEx( key,OPTIONHEIGHT_KEY,0,type,(LPBYTE)&m_height,size );
type = REG_DWORD;
size = 4;
m_width = rc2.Width();
RegSetValueEx( key,OPTIONWIDTH_KEY,0,type,(LPBYTE)&m_width,size );
m_top = (int)rc2.top; //because .top is long
RegSetValueEx( key,OPTIONTOP_KEY,0,type,(LPBYTE)&m_top,size );
// m_lft = (int)rc2.left;
// RegSetValueEx( key,OPTIONLEFT_KEY,0,type,(LPBYTE)&m_left,size );
If I uncomment the last two lines, biiig crash! m_left is just declared a simple int, just like the rest.

Appreciate your response,

Nope, Its not a typo! I found that the trouble is I am not allowe dto add any kind of member variable (private or public - DWORD, CString, int I tried). as soon as I add one, it crashes. Remove the variable and alls well. Creating a local variable is fine. I dont understand this......any ideas? Thank you,

Two things:
For some reason I had two .h files of the same class in the project even though the workspace didnt indicate it. Found it out by accident.
Second: it was still being flaky so I did a rebuildALL - now it works like a charm!

Hi,
I have a drived CArray structure defined as follows:
----------------------------------------------------
The structure MMM and the class A is defined in a main dialog (such as MyDialog.h)
Typedef struct
{
int x;
double y;
}MMM;
typedef CArray<mmm, mmm&=""> CMmmArray;
In one class called class A, I have
class A
{
....
CMmmArray m_mdata;
....
}
-----------------------------------------------------
Now, I want to access into the m_mdata from another
class (child dialog). This is MyChildDialog.h
class B
{
.....
}
How can i access and get the m_mdata in this child dialog?
Thanks in advance!

First of all, you'd do better to use vector. Secondly, put your typedef, etc. into stdafx.h, so that the whole project knows what they are, then you'll be able to access it in the usual ways.

Thanks ! but when i put the following typedef into the
stdafx.h, it contains errors in the line:
typedef CArray<mmm, mmm&=""> CMmmArray.
Typedef struct
{
int x;
double y;
}MMM;
typedef CArray CMmmArray;
How should i change this?
