You can probably start by looking at the subkeys under:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

Blocked by Networkadministrator .That b;locked port required to find out programatically.

The only way I know is using UPnP. The device blocking the ports needs to support UPnP and
UPnP needs to be enabled on the device. I don't know how many network admins allow this, since
allowing applications to open ports through firewalls and/or NAT devices negates the security.

These are WinUser resources. MFC resource IDs are located in afxres.h (which in turn includes also winres.h). You may want to check also the .rc files located in Platform SDK in ../mfc/src.

Hi all:
I wonder how the icon for the items in A/R program dialog is set?
|
|
|
|
|
Set the following reg value
Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*MyProduct*\
ValueName: DisplayIcon
Value: C:\MyProg\MyProg.exe,0 (0 being the icon no in the resource)
If you think you can than you can, if you think you can't you are right.

This is the code i am trying in visual studio 2005.
char *str = new char[100];
delete [] str;
strcpy ( str, "good_moring" );
cout<
|
|
|
|
|
The results of operation on a deleted pointer are *undefined* (thats why you should set the pointer to null right after deleting it)
If you think you can than you can, if you think you can't you are right.
|
|
|
|
|
Because the page in the process's virtual address space that str pointed to is not released right away. In fact it would probably get re-used if you immediately called new again.
In short: it's luck and it's a bug to access memory after using free/delete on it.
|
|
|
|
|
The operator new allocates the space and assigns an address to the variable. The operator delete only marks that memory as re-usable, it does not change the assigned pointer. Your code will not throw any errors because all strcpy will do is check theat the address points to memory, it will not check if it is usable or not.
If in your test code you allocated and used more memory after deleteing str and before strcpy, you may find that the same memory is being used. The golden rule is, set the address to NULL directly after calling delete.

thanks...
so better to follow the goldern rule.

why this is happening ?
Perhaps delete is only marking the memory chunk as free and strcpy doesn't matter about, as stated by MSDN:
The strcpy function copies strSource, including the terminating null character, to the location specified by strDestination. No overflow checking is performed when strings are copied or appended
try this:
char *p = new char[100];
delete [] p;
char *q = new char[100];
strcpy(p,"Hello world\n");
strcpy(q,"Good news...\n");
printf("%s", p);
printf("%s", q);
if you're a lucky boy, like me, you will see the following output:
Good news...
Good news...
hence you're loosing the freed memory.
As already stated by other posters, NEVER DO SUCH NASTY THINGS.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

I think you asked like this question you can also use of GDI+ or CImage class for read graphic files.(jpg,gif,png,..)

Hi WhiteSky,
Just now i had read your previous reply, Sorry.......

Hi,
I need to write an injection module for my application.
Which one would be the best. Code Injection or DLL Injection. What are the advantages over the other...
Heard that, DLL injection can be used in all the windows OS. but code injection can be applied only on NT Operating sys.
Is there any other advantages or problems in using either of them..
Please advice me.
Thanks.
