I am very sorry to mention this: I never had programmed in C (Dos Based), I Started straight away with C++. Actually I got concept of structural programming form PASCAL! (Hope you hear the name this language).
So I can't really help you in that! If you like I can make win32 based version of that ftp client which has no MFC dependency.

hello everyone
my code works well most of the time in debug mode,however,it failed when i ship it into .exe.i guess it may be the problem of memory leak. the code seems to have problem is as below:
for(int i=0;i<30;i++)
{
CString temp;
temp=myfunction();
if (temp!="")
{
dlg->FieldName[j]=new char[];
strcpy(dlg->FieldName[j],temp);
dlg->nColumnEnd=count;
j++;
count++;
}
}
and sometimes when debugging, it alerts as below:

How many characters are you allocating room for?

Hi all,
I found that Visual C++ .NET 2003 has the following bug
on compiling inner class of template class:
---------------------------
template <class FirstOuter, class SecondOuter>
struct Conj
{
struct Inner
{
typedef typename FirstOuter::Inner First;
typedef typename SecondOuter::Inner Second;
};
};
struct A
{
struct Inner
{
static void a(void) {};
};
};
struct B
{
struct Inner
{
static void b(void) {};
};
};
struct C
{
struct Inner
{
static void c(void) {};
};
};
int main(int, char**)
{
Conj<A, B>::Inner::Second::b(); //ok;
Conj<A, Conj<B, C> >::Inner::Second::First::b(); // ok;
Conj<Conj<A, B>, C> >::Inner::First::Second::b();
//bug! Should be compilable but trigger C2039: 'Inner': is not a member of 'operator' `globalnamespace'
Conj<A, Conj<B, C> >::Inner::Second::Second::c();
//bug! Should be compilable but triggered C2039: '__ctor' : is not a member of 'Ctor<FirstOutter, SecondOuter>::Inner'
Conj<Conj<A, B>, C> >::Inner::First::First::a();
//bug! Should be compilable but triggered C2039: 'Inner': is not a member of 'operator' `globalnamespace'
}
-----------------------------------
Any idea or workaround? Thanks.

i think you should be more specific in your message. anyway if what i understand is correct, u want to print the array k i*j times right?
if so, just do a triple nested for loop. i.e.
for (i...)
{
__for (j...)
__{
____for (k...)
____{
______// printing goes here
____}
__}
}
the underscores are just to space the code nicely.
anyway, the first way works fine, however i would recommend that u create a function for the printing of k. i.e.
void printK(int &array, int sizeofK)
{
__for (i=0; i

do you mean having a two-dim. array with arrays as elements?
No hurries, no worries.
|
|
|
|
|
exactly, that is what i want!!
|
|
|
|

I can think of two ways.
1: do it like: array[i][j*k]
all elements after j are of the second array.
2: In .NET you can create arrays of objects, an array is an object, so you could create an object array, put it in a object array ... you should be able to cast it back into an array, I think  . Better would be that the object is a class containing not only an array, but also the size of it. Sort of a CArray class. (Overload for the basic types: CString, int, double ...)
good luck.
No hurries, no worries.

what's the difference between CString and string? which one will be better and easier to use?
so far i'm always sticking to string, as i learnt it that way. someone please enlighten me the advantages of CString over string.

CString is Microsoft's string class. It has an easier syntax to the methods that it exposes. I use string by default, and CString if I have to. I'm far more likely to use bstr_t ( converts between wide and narrow strings for you ) than CString.

string was not thread safe until VS.NET I had to learn that the hard way. I believ with VS.NET when you copy one sring object to another it actually copies the entire contents of the string which can be a issue if you desire high performance. CString doesnot have the same problem. The CString with VS.NET is very impressive and very good. I recommend using it.

CStrings have thread affinity, which can be another reason to not use it.
