SYMPTOMS

In a native executable, passing a negative value to the CByte function does not generate an error. It should cause an Overflow error.

This bug has been fixed in Visual Studio 97 Service Pack 2.

MORE INFORMATION

This problem does not occur in the IDE or in P-Code executables. This problem does not occur in the Intel version of the product regardless of how the application is compiled. Once the RISC version of Visual Studio 97 Service Pack 2 is installed, code such as:
Dim b as Byte b = CByte(-2)
				
correctly results in an Overflow error regardless of how the application is compiled.
