 * Microsoft Active Directory Service Interfaces, version 2.5

SUMMARY
The ADSI help files do not specify the header or library files that you need to build ADSI applications in Visual C or Visual C++.

If you are building new code (or using the code snippets in ADSI help), you must include activeds.h, which will pull in the other ADSI header files. The ADSI APIs are Unicode so you should also define UNICODE and _UNICODE before including any system headers (for example, windows.h). If you are using the LDAP provider's OLE DB support you will also need to include oledb.h.

When you link your code you should add Adsiid.lib and Activeds.lib to your object/library modules settings. If you are using the LDAP provider's OLE DB support you will also need to add Oledb.lib.

MORE INFORMATION
An error message of the following type is created when Adsiid.lib is missing from the link libraries:

YOUR_FILE.obj : error LNK2001: unresolved external symbol _IID_IADs*

An error message of the following type is created when Activeds.lib is missing from the link libraries:

YOUR_FILE.obj : error LNK2001: unresolved external symbol [ADS_API@offset] Debug/delete.exe : fatal error LNK1120: 1 unresolved externals Error executing link.exe.
