SYMPTOMS
After you upgrade to Host Integration Server 2000 SP1, performing any of the following actions causes all Decimal data type parameters to be written to a COM Transaction Integrator (COMTI) type library file (.tlb) as native Decimal data types:
- Modifying an existing COMTI type library (.tlb)
- Creating a new COMTI type library (.tlb)
When using a COMTI .tlb file that contains native Decimal data types in Visual Basic 6, you receive the following error message:
In Host Integration Server 2000 prior to SP1, the Decimal data type parameters were written to the COMTI .tlb file as Variant data types.
CAUSE
Changes that were made in SP1 result in the Decimal data type parameters being written differently to the .tlb file. These changes were made to improve compatability with Visual Studio .NET.
These changes cause a problem because Visual Basic 6 does not support native Decimal data types. Therefore, when using early binding, the .tlb files cannot be used with Visual Basic 6.

This problem was corrected in Microsoft Host Integration Server 2000 Service Pack 2.
MORE INFORMATION
After you install the fix, you can access a new option that is available on the Interface Properties page in the COMTI Component Builder:
- Right-click the name of the interface, and then click Properties. Notice the Support old style VB Decimal Data types check box.
- COMTI Component Builder will create the resulting COMTI .tlb file using the data type that you select as follows:
- When the check box is selected, using Variant data types as it did before SP1.
- When the check box is cleared, using the native Decimal data type.
After the fix is installed, COMTI component builder can also detect whether existing COMTI .tlb files are using Variant data types or native Decimal data types, and will select or clear the check box accordingly. You can manually change this whenever you want on the Interface Properties page.
Note: The default for all new COMTI .tlb files is to use native Decimal data types.
