This code restarts the Windows shell programmatically:

HWND hwndShell = FindWindow("Progman", NULL);
PostMessage(hwndShell, WM_QUIT, 0, 0L);
WinExec("Explorer.exe",SW_SHOW);

I know for sure coz i have developed namespace extensions, if two explorers are open you need to terminate each of them using the task manager otherwize the namespace is not unloaded from the memory.

So i dont think ONE instance is the right answer always, there can be more than one.

I need to disable CListCtrl, so user won't be able to do anything with list control.
I'm calling CListCtrl::EnableWindow(FALSE); to do that, but it also
displays list control in gray color.
How to disable this without changing the color to gray ?

Thanks !

In general you cannot change the color of a control that is in a disabled state without subclassing.

I want to convert a char * to unsigned char[](or fill that array with char * string) but I can't find it, I can do reverse of it but not this one.

It will be helpfull with little bit of code that you are trying to convert.

char *pszString;
pszString = new char[20];

now pszString can store upto 19 bytes of string.
you can either access it as
pszstring,
if you want to access each char then
*(pszString+index)
or
pszString[index]

hope i answered ur question properly.

WRONG!
You allocated 20, right? How can you say it can hold 19 bytes then?
You know, it is starting from 0, that means 0 is the first element.

But ASCII 0 is still a valid character, it just happens to be a special one. Allocating 20 bytes on the heap means you can store 20 bytes.

Of course not. I was simply saying that your "now pszString can store upto 19 bytes of string" comment was off by one.

Thanks for reply, I have a problem now, see this code:

for(int i = 0 ; i < sizeof(mypointer);i++)
   buffer1[i] = *(val+i);

sizeof(mypointer) cause the loop only run 3 times and other chars do not copy to array , if I change it to a larger number like 200 it works ok but I don't know how to get size of it dynamiclly.

Change to:

strlen(mypointer)

When you do sizeof of a pointer it returns the size of the pointer, not the length of the string.

change it to this way.

for(int i = 0 ; *(val+i)!=NULL;i++)   
    buffer1[i] = *(val+i);

since pointers are always 4 bytes sizeof(anypointer) will always return 4

strlen will give you the size of the string pointed by the pointer.

If I understand you, you want to copy the data from a char* to a unsigned char[]?

char* p = "bla bla";
unsigned char uch[WHATEVER_SIZE];
strcpy(reinterpret_cast<char*>(uch), p);
cout << uch << endl;
