Introduction

In my previous article ACF Does Shell � Part 1, I talked about how to use the Item class to navigate Windows Shell and retrieve item information. In this article, I will show you how to use the Item and LinkItem classes to create and open shell links (shortcuts). If you are not familiar with the Item class, please check my previous article first.

Creating shell links

The following code snippet shows how to create a link to "My Documents" and then save it to desktop:

ItemPtr target = new Item(SpecialFolder::Personal); // My Documents

ItemPtr location = Item::get_Desktop(); // Desktop


LinkItemPtr link = new LinkItem(target); // The link

link->Save(location);

As you can see, the API is very straightforward.

Opening existing shell links

The following code snippet shows how to open an existing link file and retrieve its properties (description, target, arguments, etc.):

StringPtr path = ...; // Path to a file

ItemPtr item = new Item(path);

if (item->IsLink) {
    LinkItemPtr link = item->LinkItem;

    StringPtr description = link->Description;
    StringPtr targetPath = link->Target->FileSysPath;
    StringPtr args = link->Arguments;
    StringPtr dir = link->WorkingDirectory;
}

The sample application demonstrates how to use these classes.
