# REGSVR Sample: Invokes Self-Registration Code

The REGSVR sample is the source code to the existing REGSVR32.EXE utility. This utility is used to invoke the self-registration code built into ActiveX controls that adds or removes a control's information in the registry. Developers can use this sample to modify the behavior of the REGSVR32 utility.

REGSVR32.EXE can be found in the \Microsoft Visual Studio .NET 2003\Common7\Tools\Bin directory. For more information on using REGSVR32, see MFC ActiveX Controls: Distributing ActiveX Controls.

Security Note
This sample code is provided to illustrate a concept and should not be used in applications or Web sites, as it may not illustrate the safest coding practices.

# Building the Sample

#### To build and run the REGSVR sample

1. Open the solution regsvr.sln.

2. On the Build menu, click Build.

See Controls Samples for details on adding a control to the Toolbox, manually registering a control, and using the ActiveX Control Test Container.

# Keywords

The REGSVR sample demonstrates the following keywords:

FreeLibrary; GetLastError; GetProcAddress; LoadLibrary; LoadString; MessageBox; OleInitialize; OleUninitialize; WinMain; lstrcpy; lstrlen; wsprintf

Note
Some samples, such as this one, have not been modified to reflect the changes in the Visual C++ wizards, libraries, and compiler, but still demonstrate how to complete your desired task.
