Подскажите пожалуйста, кому не в лом...
Я из ListBox копирую файлы в папку на "С\Base\" + ID, который я беру из базы...Происходит следующее: когда в ListBox указано несколько файлов, копирование происходит успешно и в нужную папку, а когда только один файл-происходит что-то непонятное, что я делаю не так?

Код: from1,2 - типа string
fmAttachement.ListBox1.Count>0 then
begin
From1:=fmAttachement.ListBox1.Items.Strings[0];
for i := 1 to fmAttachement.ListBox1.Count-1 do
From1:=From1 + #0 + fmAttachement.ListBox1.Items.Strings[i];
From1:=From1 + #0 + #0;
From2:="C:\Base\" + dmMy.TBLRequestsID.AsString;

with SHFileOpStruct do
begin
Wnd := Handle;
wFunc := FO_Copy;
pFrom := PChar(From1);
pTo := PChar(From2);
fFlags := FOF_NOCONFIRMMKDIR;
fAnyOperationsAborted := False;
hNameMappings := nil;
lpszProgressTitle := nil;
end;
SHFileOperation( SHFileOpStruct );
end;

Contains information that the SHFileOperation function uses to perform file operations.

typedef struct _SHFILEOPSTRUCT { // shfos
HWND hwnd;
UINT wFunc;
LPCSTR pFrom;
LPCSTR pTo;
FILEOP_FLAGS fFlags;
BOOL fAnyOperationsAborted;
LPVOID hNameMappings;
LPCSTR lpszProgressTitle;
} SHFILEOPSTRUCT, FAR *LPSHFILEOPSTRUCT;

Members

hwnd

Handle of the dialog box to use to display information about the status of the operation.

wFunc

Operation to perform. This member can be one of the following values:

FO_COPY Copies the files specified by pFrom to the location specified by pTo.
FO_DELETE Deletes the files specified by pFrom (pTo is ignored).
FO_MOVE Moves the files specified by pFrom to the location specified by pTo.
FO_RENAME Renames the files specified by pFrom.

pFrom

Pointer to a buffer that specifies one or more source file names. Multiple names must be null-separated. The list of names must be double null-terminated.

pTo

Pointer to a buffer that contains the name of the destination file or directory. The buffer can contain mutiple destination file names if the fFlags member specifies FOF_MULTIDESTFILES. Multiple names must be null-separated. The list of names must be double null-terminated.

fFlags

Flags that control the file operation. This member can be a combination of the following values:

FOF_ALLOWUNDO Preserves undo information, if possible.
FOF_CONFIRMMOUSE Not implemented.
FOF_FILESONLY Performs the operation only on files if a wildcard filename (*.*) is specified.
FOF_MULTIDESTFILES Indicates that the pTo member specifies multiple destination files (one for each source file) rather than one directory where all source files are to be deposited.
FOF_NOCONFIRMATION Responds with "yes to all" for any dialog box that is displayed.
FOF_NOCONFIRMMKDIR Does not confirm the creation of a new directory if the operation requires one to be created.
FOF_RENAMEONCOLLISION Gives the file being operated on a new name (such as "Copy #1 of...") in a move, copy, or rename operation if a file of the target name already exists.
FOF_SILENT Does not display a progress dialog box.
FOF_SIMPLEPROGRESS Displays a progress dialog box, but does not show the filenames.
FOF_WANTMAPPINGHANDLE Fills in the hNameMappings member. The handle must be freed by using the SHFreeNameMappings function.

fAnyOperationsAborted

Value that receives TRUE if the user aborted any file operations before they were completed or FALSE otherwise.

hNameMappings

Handle of a filename mapping object that contains an array of SHNAMEMAPPING structures. Each structure contains the old and new path names for each file that was moved, copied, or renamed. This member is used only if fFlags includes FOF_WANTMAPPINGHANDLE.

lpszProgressTitle

Pointer to a string to use as the title for a progress dialog box. This member is used only if fFlags includes FOF_SIMPLEPROGRESS.

Remarks

If pFrom or pTo are unqualified names, the current directories are taken from the global current drive and directory settings as managed by the GetCurrentDirectory and SetCurrentDirectory functions.
