Technical Support Notes

After upgrading EPSON RC+ and VB Guide to a newer version, you may encounter errors when you attempt to run your Visual C++ application.  These errors can be caused by a typelib change in one of the ActiveX controls in VB Guide.  Sometimes when new properties or methods are added, the IDs of previous properties and methods will change, causing a mismatch between spelcom3.cpp in your VC++ project and the new spelcom3.ocx control.

Please follow these steps when upgrading:

1.  Run the EPSON RC+ setup program in the usual manner to upgrade.

2.  Open each of your projects from EPSON RC+ and build them.

3.  Copy the files spelcom3.cpp and spelcom3.h from the d:\epsonrc\vbguide.v30\vc\demos\demo1 directory to each of your VC++ project directories.  These are the default filenames used when you first added the SPELCom ActiveX control to your project.  If you renamed these files, then you must rename the demo files to the new names.

4.  Copy the file scomdefs.h from the d:\epsonrc\vbguide.v30\vc directory to each of your VC++ projects.  This may not be necessary if you are not using this file, which defines constants for SPELCom.  But it's a good idea to update the file.

5.  Rebuild your VC++ projects.
