如何使用delphi xe3复制一个类似.pst的锁定文件 [英] How to copy a locked file like .pst using delphi xe3

问题描述

我正在努力寻找以下问题的答案。任何和所有的帮助将不胜感激。

在outlook打开的时候，我正在使用以下代码来尝试复制outlook.pst文件。我不能让它成功。
它不给出错误，它只是不复制文件。

  copyfile（'C：\Users \Administrator\Documents\Outlook Files\Outlook.pst'，'F：\Outlook.pst'）; 
  

如果你们知道我将如何复制这样的锁定文件，请协助。 p>

我已经尝试发现，TFilestream也不起作用。

这2个是我知道的唯一选项。任何帮助将不胜感激。

谢谢

我已经尝试了以下代码，并得到一个错误，说文件是在另一个进程中使用（outlook）。

  procedure TForm1.Button2Click（Sender：TObject）; 
 var 
 NewFileName：string; 
 NewFile：TFileStream; 
 OldFile：TFileStream; 
开始
 NewFileName：='F：\outlook.pst'; 
 OldFile：= TFileStream.Create（'C：\Users\Administrator\Documents\Outlook Files\outlook.pst'，fmOpenRead或fmShareDenyWrite）; 
 try 
 NewFile：= TFileStream.Create（NewFileName，fmCreate或fmShareDenyNone）; 
 try 
 NewFile.CopyFrom（OldFile，OldFile.Size）; 
 finally 
 FreeAndNil（NewFile）; 
结束
 finally 
 FreeAndNil（OldFile）; 
结束
结束

解决方案

PST提供程序锁定PST文件，直到父进程终止。即使您从Outlook关闭PST文件，由于性能原因，它将保持打开30分钟。

您是否以编程方式在Outlook中打开PST文件？ p>

I am struggling to find an answer to the following problem. Any and all help would be appreciated.

I am using the following code to try and copy an outlook.pst file while outlook is open. And i cannot get it to succeed. It does not give an error, it just doesnt copy the file.

copyfile('C:\Users\Administrator\Documents\Outlook Files\Outlook.pst','F:\Outlook.pst');

If you guys know how i will be able to copy a locked file like that please assist.

I have tried and found that TFilestream also does not work.

And those 2 are the only options i know off. any help would be greatly appreciated.

Thank You

I have tried the following code as-well and get an error saying that the file is in use from another process(outlook).

procedure TForm1.Button2Click(Sender: TObject);
var
   NewFileName: string;
   NewFile: TFileStream;
   OldFile: TFileStream;
Begin
           NewFileName:='F:\outlook.pst';
           OldFile := TFileStream.Create('C:\Users\Administrator\Documents\Outlook Files\outlook.pst', fmOpenRead or fmShareDenyWrite);
            try
              NewFile := TFileStream.Create(NewFileName, fmCreate or fmShareDenyNone);
              try
                NewFile.CopyFrom(OldFile, OldFile.Size);
              finally
                FreeAndNil(NewFile);
              end;
            finally
              FreeAndNil(OldFile);
            end;
end;

解决方案

PST provider locks PST files until the parent process terminates. Even if you close the PST file from Outlook, it will be kept open for 30 minutes for the performance reasons.

Do you programmatically open the PST file in Outlook?
