Summary:
If you distribute the source code (.FRM) of a program that uses the
custom controls of the Professional Toolkit for Visual Basic, you must
also distribute the necessary custom control files (.VBX, .DLL, and/or
.EXE support files, as described in the "Microsoft Professional
Toolkit for Visual Basic: Custom Control Reference").
If a user has not purchased the Professional Toolkit for Visual Basic
and receives a program containing an .FRM file written with the
Professional Toolkit, then the Visual Basic programming environment
(VB.EXE) will not be able to load the program, and will display the
following error message:
License file for custom control not found. You do not have
an appropriate license to use this custom control in the
design environment.
Note that anyone who acquires a program in the form of an executable
(.EXE) file that uses the custom controls from the Visual Basic
Professional Toolkit will be able to run that program with no error.
This information applies to Microsoft Professional Toolkit for
Microsoft Visual Basic programming system version 1.0 for Windows.
More Information:
The licensing file VB.LIC is installed by the Visual Basic
Professional Toolkit SETUP.EXE program. This licensing file is
installed into the Window's \SYSTEM subdirectory.
A custom control's startup code checks to see if this VB.LIC licensing
file exists when the control is loaded into the environment. If the
file does not exist, or is corrupt, the control aborts the loading
process and displays the Alter message box:
License file for custom control not found. You do not have
an appropriate license to use this custom control in the
design environment.
