Adding MDSC.idl and DMProperties.idl to the project
IMetadataLoad is defined in MDSC.idl, which is supplied with the UNICOM Intelligence Developer Documentation Library. By default, the file is installed into [INSTALL_FOLDER]\IBM\SPSS\DataCollection\7\DDL\Code\DSCs\VC6\MDSC.
You also need to add DMProperties.idl to the project, because it is used by MDSC.idl. DMProperties.idl is installed with the Visual C++ sample CDSC project, which by default is installed into [INSTALL_FOLDER]\IBM\SPSS\DataCollection\7\DDL\Code\DSCs\VC6\mrXmlDsc. You can optionally copy these two files into the project folder.
1 From the Visual C++ menus, click Project > Add to Project > Files.
2 Browse to the appropriate location, select MDSC.idl, and click OK.
3 Browse to the appropriate location, select DMProperties.idl, and click OK.
4 In the Visual C++ Workspace pane, click the File View tab.
You can now see MDSC.idl and DMProperties.idl in the list of source files.
5 Select MDSC.idl from the list of Source Files.
6 From the Project menu, choose Settings.
The Project Settings dialog opens.
7 In the Settings For list, select All Configurations.
8 On the General tab, select Always use custom build step, and then click the Custom Build tab.
9 In the Description text box, enter the following text:
Compiling $(InputPath)
10 In the Commands text box, enter the following text:
midl "$(InputPath)" /h "$(ProjDir)\$(InputName).h" /iid "$(ProjDir)\$(InputName)_i.c" /Oicf
11 In the Outputs text box, enter the following text:
$(ProjDir)\$(InputName).h
$(ProjDir)\$(InputName)_i.c
This defines MDSC.h and MDSC_i.c as dependent on MDSC.idl and instructs Visual C++ to build them whenever they are required.
12 Click OK.
