SAS Custom Task Examples

"Ready to Run" Examples and Source Code for Custom Tasks for SAS Enterprise Guide using Microsoft .NET

Use the following links to access the example projects that were developed for Custom Tasks for SAS Enterprise Guide using Microsoft .NET, by Chris Hemedinger.

About the Examples

The book includes detailed descriptions about several custom task projects. These projects are provided by the author for your use in two ways:

• As binaries (DLL files) that are ready to run in SAS Enterprise Guide and the SAS Add-In for Microsoft Office. The binary files are packaged as Zip files for download.

  Note: Additional steps may be required to run the prepared task examples in your environment. See Special steps for running task examples for more information.

• As source code, including the Microsoft Visual Studio projects and code that you can use to view, modify, and build the examples yourself. The source projects are packaged as Zip files for download.

Special steps for running task examples

Recent versions of SAS Enterprise Guide (version 5.1 and later) use Microsoft .NET 4.0, which enforces additional security requirements before running custom task DLLs that you download from the Web. Because these task DLLs are downloaded from the Internet, the Microsoft .NET runtime does not automatically "trust" them as it would trust a properly installed application. To enable the task to run, you must first "unblock" the file using Windows Explorer.

1. Using Windows Explorer, browse to the assembly (DLL) that you downloaded from the samples and extracted from the Zip file.
2. Right-click on the DLL file, and from the shortcut menu, select Properties. The Properties dialog box opens.
3. On the General tab, click Unblock to indicate that this DLL is trusted (Note: the Unblock button will not appear if the assembly is already unblocked and available.)
4. Click OK to close the Properties dialog box.

You can read more about this security feature and behavior in this Microsoft Knowledge Base article. If you build the examples yourself, using the supplied projects and source code in Microsoft Visual Studio, you will not need to unblock the DLLs as you build them.
