BOOL CopyFile(
LPCTSTR lpExistingFileName,
LPCTSTR lpNewFileName,
BOOL bFailIfExists );
|
| | | | FoxPro declaration: | | |
DECLARE INTEGER CopyFile IN kernel32;
STRING lpExistingFileName,;
STRING lpNewFileName,;
INTEGER bFailIfExists
|
| | | | Parameters: | | lpExistingFileName
[in] Long pointer to a null-terminated string that specifies the name of an existing file.
lpNewFileName

bFailIfExists
[in] Boolean that specifies how this operation is to proceed if a file of the same name as that specified by lpNewFileName already exists. If this parameter is TRUE and the new file already exists, the function fails. If this parameter is FALSE and the new file already exists, the function overwrites the existing file and succeeds |

| | | My comment: | | The native COPY FILE command cannot copy a file that is open (3. File is in use).
With the CopyFile, both the source and the destination can stay open -- like text files modified, DBF files in use and so on -- and still the copying occurs. Of course, any uncommitted changes do not appear in the target file.
To copy files with a progress dialog box use the SHFileOperation function.

| CopyFile is a perfect function.
You can redirect a remote barcode printer in Novell network by using CopyFile. (Even you don"t need install the Printer driver!!)
For example, if you write a text file according to barcode printer gride, such as heat control, label tab space etc.
CopyFile(abc.txt, [\\UserB\Datamax])
Note:
The UserB PC cannot use CopyFile API to call itself Printer nor call LPT1, I donno why but observe it in real test. | |
