Encode, or encrypt, means to convert data or some physical quantity into a given format (e.g., ROT-13). Decode, or decrypt, means to convert code into ordinary language. For example, before you send a password to someone via e-mail, you would first encrypt it so that it is not easily readable. When the recipient opens your e-mail, they would need to decrypt the password before being able to use it. If my password was saturday and I encrypted it using ROT-13, the result would be fngheqnl.

Do not get the desktop window DC. It causes serious problems. Instead of this HWND hDesktopWnd=::GetDesktopWindow(); HDC hDesktopDC=::GetDC(hDesktopWnd); write this HDC hDesktopDC = ::CreateDC("DISPLAY",0,0,0);

The documentation in the Platform SDK covers this in detail, but in brief this function allows you to access driver-specific functions that are not exposed by the Windows GDI. The specific device is passed to the function using its handle, hdc. The device driver function is specified by nEscape, while lpszInData is a pointer to whatever data is required as input for the function. The cbInput parameter specifies the size of the structure indicated by lpszInData in bytes. Similarly, the lpszOutData parameter is a pointer to the structure where you want the results to be stored, and cbOutput contains the size, in bytes, of this structure. ExtEscape returns a positive value if the call is successful, and 0 if the requested function doesn't exist. A negative return value indicates an error. Several predefined values exist for nEscape, primarily related to printers, but other than these you are free to specify any value supported by the target driver.

HWND is a pointer to an insternal structure that contains the state information for a window. HINSTANCE is a pointer to an internal structure that contains the executable module state information. There is only one HINSTANCE, but there may be 0 or more HWND for a given program. Note: There are also HMODULE, which is a pointer to an internal structure that contains the state information for a module - a module is a dll or exe ... which means that HINSTANCE can also be thought of as being a special type of HMODULE. You use HWND to manipulate windows - move them, resize them, ... You use HINSTANCE/HMODULE to access resources in the exe or dll - icons, bitmaps, strings, ... ...cmk Save the whales - collect the whole set
