Hi Richard,
Thanks for your reply..Its mainly intended for VS2013. I am not able to do for VS2010
Thanks,

Well now you know where to look you can get any specific details for VS2010.

Hi Richard,
Thanks again for your reply. Actually I came to know from link that "Edit and continue" feature is not available for X64 bit application in VS2010..In order to be make sure I wanted to hear it from expert team who had already having hands on experience on this.
Thanks,
SMA

Well thanks for your comment, but I have never used Edit & Continue in 20 years of Windows programming.
|
|
|
|

I'm going to have to second Richard on this... I've never used Edit & Continue... I wouldn't depend on a feature that's not really widely used as that (none of the other developers in my company use it either).
|
|
|
|
|
I have never used it either.
Rather curious as to what development methodology would be in use such that this would be a feature that one could ever rely on in a non-trivial way.
|
|
|
|
|
Yeah, I'd be curious too. It's not a very helpful feature, sounds more like a feature added for the sake of adding bullet point highlights for a new release of VS.

I very rarely use it to fix minor typo-like errors, such as replacing < with <=, or changing literal values in assignments or function calls to something else. The reason is that I'm often confronted with deep levels of function calls with multiple nested loops, and getting back to the same point of debugging can be very time consuming.
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

True, but nothing that you couldn't do with a bookmark and/or a conditional break point.

Hi,
No it is not implemented for 64 bit. Furthermore x64 edit and continue for unmanaged is not implemented on VS versions all the way up to VS2013++.
Best Wishes,

I have a class (taken from somewhere). Here, I have a member like this:
public:
void SetBitmapDataSize(const int x, const int y);
private:
int m_PixelNumberX;
int m_PixelNumberY;
vector<vector<COLORREF> > BitmapData;
and SetBitmapDataSize is implemented:
void CBitmapOp::SetBitmapDataSize(const int x, const int y)
{
m_PixelNumberX = x;
m_PixelNumberY = y;
if((x>=0) && (y>=0))
{
BitmapData.resize(m_PixelNumberX);
for(int x = 0; x < m_PixelNumberX; x++)
BitmapData[x].resize(m_PixelNumberY);
}
}
Now, I want to replace vector<vector<colorref> > with this CArray:
I had tried:
private:
int m_PixelNumberX;
int m_PixelNumberY;
CArray< CArray<COLORREF, COLORREF&>, CArray<COLORREF, COLORREF&> > m_arrBitmapData;
my question is, how can replace vector.resize method, and how can I return CArray< CArray<COLORREF, COLORREF&>, CArray<COLORREF, COLORREF&> > data type ?
Thank you.

Ok, resize issue has been solved.
Secondly, as long m_arrBitmapData is private memeber, I want to return this memeber through a public method, I mean from this class ...
Something like that:
public:
CArray< CArray<COLORREF, COLORREF&>, CArray<COLORREF, COLORREF&> > GetBitmapArray(){return m_arrBitmapData;}
because this trial give me:
error C2558: class 'CArray<class CArray<unsigned long,unsigned long &>,class CArray<unsigned long,unsigned long &> >' : no copy constructor available

Just return a constant reference as in
const CArray< CArray<COLORREF, COLORREF&>, CArray<COLORREF, COLORREF&> > & GetBitmapArray()
The good thing about pessimism is, that you are always either right or pleasently surprised.

I think is working ...  I have one more question: there is a way to pass a paramanter as CArray< CArray<COLORREF, COLORREF&>, CArray<COLORREF, COLORREF&> >, just like:
void SetPlotData(CArray< CArray<COLORREF, COLORREF&>, CArray<COLORREF, COLORREF&> > InputArray);
and
void CGraphCtrl::SetPlotData(CArray< CArray<COLORREF, COLORREF&>, CArray<COLORREF, COLORREF&> > InputArray)
{
if ((m_PixelNumberX>0) && (m_PixelNumberY > 0))
{
PlotData = InputArray;
}
}
because code above doesn't work:
error C2582: 'CArray<class CArray<unsigned long,unsigned long &>,class CArray<unsigned long,unsigned long &> >' : 'operator =' function is unavailable
As soon as I solve this error, my program will run ...

That's not advisable. I wouldn't do it. As matter of fact the vector container is much better than the CArray one.
Quote: how can replace vector.resize method,
Use the Carray::SetSize[^] method.
Quote: how can I return CArray< CArray<colorref, colorref&="">, CArray<colorref, colorref&=""> > data type
The same way you return other data, e.g.
return m_arrBitmapData;
THESE PEOPLE REALLY BOTHER ME!! How can they know what you should do without knowing what you want done?!?!

I would neither store nor return the bitmap data in that way. What you are creating here is a so-called "ragged" array, in which each row can have a different length. In a bitmap this luxury is not needed, all rows are of equal length by definition. Therefore a one-dimensional array is good enough and in some regards even superior.
a) A one-dimensional array can be allocated in one chunk (whereas your ragged array needs N allocations, N being the number of rows)
b) A one-dimensional array does not incur the overhead that comes with a ragged array, which is easily 3 x 64bits per row.
To access the members of the one-dimensional array in a 2D fashion, simply use the algorithm:
index of pixel (x, y) = x + y*pixelsPerRow
As a return value for your access function I would suggest you use a simple pointer (const COLORREF*).
For the caller to know how to access that 1D array you should provide addition access functions for the number or rows and number of columns.

Ohh, I would love to get rif of 2D array ... I had taken the class from here[^], could you assit me how to give up vector<vector<colorref>> BitmapData ? If I am not asking too much ... I will start working, to see what is happen ... See you.

It is not very difficult to get rid of this 2D array.
1) replace it with a vector<colorref> m_bitmapData;
2) Replace any reference to the old BitmapData array as follows:
BitmapData[x][y] should be replaced by m_bitmapData[x + m_PixelNumberX*y]
3) In SetBitmapDataSize allocate the new array by
m_bitmapData.resize (x * y);
Change the function interfaces accordingly. Should be really easy.

Kindly thank you NV3 ! I will let you know what I have done.

Great ! Is working, just like the original one ... I didn't replace 2D array by vector, but with CArray ... and is working ! Kindly thank you, NV3 !

Let two exes use same dll in windows platform at particular time.Then what is shared internally?Please correct me if I am wrong.
-Dll file in Hard disk is shared(Single copy).
-Instructions in Dll are loaded once and code can be used by both the executable.
-The objects in the Dlls are also shared by both executable.
Please clear me - The mechanism in windows os. whether this is same across all OS.
Thank you in Advance.

From MSDN[^]:
DLLs also help reduce memory overhead when several applications use the same functionality at the same time, because although each application receives its own copy of the DLL data, the applications share the DLL code.

@CPAllinii
Thank you for answer. But if two dlls(having same signature) in two different directories and linked by tw different executable. Then what will happened? Is the design same across different OS.
Please answer.
