use SetCursor api! read more about it in MSDN documentation

See SetCursor[^]
You need to google first, if you have "It's urgent please" mentioned in your question.

First you have to create the cursor using the resource editor using your drawing skills.

Use the following APIs.
First load the required cursor using either.
1) LoadCursor(NULL, IDC_ARROW);//User for arrow cursor
2) HCURSOR LoadCursorFromFile( LPCTSTR lpFileName); //Give the name of the .CUR file (Pen cursor file)as parameter.
Both these functions return HCURSOR.
Then set this cursor using API.
HCURSOR SetCursor(HCURSOR hCursor);
Thanks,

There are n arrays, and there are several elements in each.
Count of array and count of elements in array are variable.
A1{a1,a2,a3,an1} //there are n1 elements in array A1
B1{b1,b2,b4,bn2} //there are n2 elements in array B1
.....
N1{n1..nn}  //there are n elements in array N1
I need all the combination which are composed with one element of every array,order is same as the array's
like:
a1,b1,.....n1
a1,b2,.....n2
...
a2,b1,.....n1
...
an1,bn2,....nn

what about stl::Vector, you can use like this :-
#include<vector>
using namespace std;
typedef vector<int> vecINT;
typedef vector<vecINT> vecINTINT;
vecINTINT vecArrays;
vecINT vecA;
vecA = A1{a1,a2,a3,an1}
a.push_back(vecA);

Thank you very much for your reply, but I am not quite clear about it. Would please explain it in detail? I need a algorithm to get all the combinations.

You've just to write a loop for each array (and nest the loops) is it difficult?
You may also use recursion.

recusion, sometimes it's quite difficult even for seasoned programmer. Though, recursion is good programming practice, come handy when you travelling through tree like data structure.. but it's a pain when you have to debug it

Because the count of array is variable, it is difficult to use loop. Recursion is good idea, but would you please write some sample code for me? thank u!!![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Hai!
In my application i have developed a code to draw an image from pixel data present in byte array. i get this byte array by reading an image file present in a location.
I was succesfully displaying (.png, .gif, .jpg, .bmp) but when i tried to display .j2k and .jp2 images using the same code my application displays blank or doesn't display image at all. I came to know that windows doesnot support .jp2 and .j2k images.
Now my doubt is if windows doesnot support them can i be able to display those (.jp2 and .j2k) images on my dialog (assuming i have correctly coded to display an image from byte array of a image file)?
Thanks!

Hai!
My application creates an .jp2 image file, i am not able to display it on my dialog, so i thought of using a Image converter to convert this .jp2 image to .jpg image, as i am able to display .jpg images on my dialog.
So can you please suggest me any free converter and how to implement it in my application to convert .jp2 image to .jpg image.
I am developing my application in eVC++ for a WIN CE Device and using Pocket PC 2003 SDK.
Thanks!

i declared the following code
class A
{
int i;
public:
void Showi()
{
i=10;
printf("\n i:%d ",i);
}
};
void main()
{
A *p= new A();
p->Showi();
if(p)
{
delete p;
printf("\n p deleted ");
}
p->Showi();
}
the problem is even after i deleted pointer p ..the call to Showi() works....does it mean p is deleted after sometime(since i heard VS 2005 uses GC)?
i am using VC++ 2005 express edition.

No, there's no such thing as garbage collector in C++. The fact that the call doesn't crash is probably pure luck (edit: see below). In fact you can always call a non virtual function on an object and the function will get called without problems (even if your object is NULL). The problem arise when you try to access data member of the class, in that case the troubles begin . If we take the example of the NULL pointer, an offset will be added to the address of the this pointer (NULL in that case) to be able to reach a specific member of the class. But the address is still invalid (NULL + an offset is still invalid).
In your case, what happened certainly is that when the function is called, the memory of your object has been released but as you didn't allocate any memory after that, the data is still in memory. Now, if you add some code to allocate memory just after the delete, it is possible that the memory used by your class previously will be overwritten by new data.
In fact, when you delete an object, it simply means that the memory is not protected anymore and that it can be reused for something else. If nobody is using it, it still contains the old data.
EDIT: in fact the call will never crash because even if the memory of your integer is overwritten, it can always be accessed without any problem. Of course, in that case you will end up with corrupted data.

Hi All,
I am trying to pass the values to managed code( C# ) to unmanaged code( C++ ). The following is the example code
[DllImport("Helper.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
private extern static bool Sample(long AccessibleContext,long vm);
<p> </p>
long ac = 10;
long id = 20;
Sample(ac,id);
<p> </p>
EXTERN_C __declspec(dllexport) BOOL Sample( long ac ,long id)
{
long sa;
sa = ac + id;
return true;
}
I am not always getting the value of the second parameter (ie "id") in C++ code, it comes as 0 but i am getting the first parameter value.
How can i resolve this problem?
Thanks in advance.
