MoveFile Function
Moves an existing file or a directory, including its children.

Syntax
C++
BOOL WINAPI MoveFile(
  __in  LPCTSTR lpExistingFileName,
  __in  LPCTSTR lpNewFileName
);

Parameters
lpExistingFileName [in]
    The current name of the file or directory on the local computer.
lpNewFileName [in]
    The new name for the file or directory. The new name must not already exist. A new file may be on a different file system or drive. A new directory must be on the same drive.

Return Value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.


GetLastError Function

Retrieves the calling thread's last-error code value. The last-error code is maintained on a per-thread basis. Multiple threads do not overwrite each other's last-error code.

    Visual Basic:  Applications should call err.LastDllError instead of GetLastError.

Syntax
C++
DWORD WINAPI GetLastError(void);

Return Value
The return value is the calling thread's last-error code.

To obtain an error string for system error codes, use the FormatMessage function.

There are just three I could think of as the most prominent ones (others should be rare occasions):
//
// MessageId: ERROR_FILE_NOT_FOUND
//
// MessageText:
//
//  The system cannot find the file specified.
//
#define ERROR_FILE_NOT_FOUND             2L
 
//
// MessageId: ERROR_PATH_NOT_FOUND
//
// MessageText:
//
//  The system cannot find the path specified.
//
#define ERROR_PATH_NOT_FOUND             3L
 
//
// MessageId: ERROR_ACCESS_DENIED
//
// MessageText:
//
//  Access is denied.
//
#define ERROR_ACCESS_DENIED              5L

Hello,

I use this code to the error as normal text.
Exchange MAKELANGID(LANG_GERMAN, SUBLANG_GERMAN) with your language and show the real error so the user can do something.

Stefan
CString returnString = GetLastErrorAsString(GetLastError());
 
 
CString GetLastErrorAsString(DWORD _errorID)
{
	char		GetLastErrorText[1024];
	CString		tempS;
 
	memset(GetLastErrorText, 0x0, sizeof(GetLastErrorText));
 
	FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, _errorID, MAKELANGID(LANG_GERMAN, SUBLANG_GERMAN), GetLastErrorText, 1024, NULL );
 
	tempS = GetLastErrorText;
	tempS.TrimRight();
 
	return tempS;
}
