[英]How to set creation time of existing file in Inno Setup Pascal Script
When copying a file by FileCopy
(or also RenameFile
) from a directory to another one an original creation time changes to the current date.通过FileCopy
(或RenameFile
)将文件从一个目录复制到另一个目录时,原始创建时间更改为当前日期。 I would like to set the creation time to the original one.我想将创建时间设置为原始时间。
I can get the original time values by FindFirst
, but how to get a handle of a file to use when calling SetFileTime
?我可以通过FindFirst
获取原始时间值,但是如何在调用SetFileTime
时获取要使用的文件句柄?
In the [Code]
section of Inno Setup, I have this code:在 Inno Setup 的[Code]
部分,我有以下代码:
If FileCopy(F1, F2,False) then
If FindFirst(F1,FindRec) then
Try
Fhandle := ??????????? (FindRec.FindHandle don't works)
SetFileTime(
Fhandle, FindRec.CreationTime, FindRec.LastAccessTime, FindRec.LastWriteTime)
finally
FindClose(FindRec);
end
EDIT:编辑:
After the answer of Martin I have modified the code as follow ( sorry if is far than perfect... I am a VB.NET programmer, not a Pascal programmer):在 Martin 的回答之后,我修改了代码如下(对不起,如果远非完美......我是 VB.NET 程序员,而不是 Pascal 程序员):
{ C1 and C2 are full Paths }
if Not FileCopy(C1, C2, False) then
begin
MsgBox('Data reading error 01. Setup will be aborted.', mbError, MB_OK);
Result := false;
exit;
end;
if FindFirst(C2, FindRec) then
try
begin
MyTime := FindRec.LastWriteTime //remains the original one
end;
finally
FindClose(FindRec);
end
else
begin
MsgBox('Data reading error 02. Setup will be aborted.', mbError, MB_OK);
Result := false;
exit;
end;
end;
FileStream := TFileStream.Create(C2, fmOpenReadWrite);
Try
if not SetFileTime(FileStream.Handle, MyTime, MyTime, MyTime) Then
begin
MsgBox('Data reading error 03. Setup will be aborted.', mbError, MB_OK);
Result := false;
exit;
end;
Finally
FileStream.Free;
end;
To obtain a handle of a file, you can use TFileStream
class :要获取文件句柄,可以使用TFileStream
类:
var
FileStream: TFileStream;
begin
{ ... }
FileStream := TFileStream.Create(FileName, fmOpenReadWrite);
try
SetFileTime(FileStream.Handle, CreationTime, LastAccessTime, LastWriteTime);
finally
FileStream .Free;
end;
end;
Though as @Ken wrote, in most cases, it would be easier to use [Files]
section entry with an external
flag .尽管正如@Ken 所写,在大多数情况下,使用带有external
标志的[Files]
部分条目会更容易。
