Jam.Shell.Dialogs.FileOperation.TJamFileOperation

Perform file operations.

Syntax

Pascal

TJamFileOperation = class(TComponent);

Description

If multiple operation are started asynchronous they are added to the progress dialog window.

Remarks

TJamFileOperation is a component to perform file operations like copy, move, rename or delete. It has to be activated like a TOpenDialog, with the call of the Execute method. To perform a single operation first specify the requested operation by setting Operation and use SourceFiles to add files or folders. After that specify a destination by setting Destination and call Execute.

Example 1

The following sample shows how to copy a single file to the root of drive D:</c>:

  JamFileOperation.Operation := otCopy;
  JamFileOperation.SourceFiles.Add('C:\Windows\explorer.exe'); // You may add more of this line or use AddStrings()
  JamFileOperation.Destination := 'D:\';
  JamFileOperation.Execute();

Example 2

The same can also be done in a simplier way:

  TJamFileOperation.Copy('C:\Windows\explorer.exe', 'D:');

In this case the operation is also performed on a background thread where the dialog is not modal.
