Subject IBO4 & Infopower3
Author stevenggibb
For several years I have been providing maintenance, and enhancements
for software for a client. The applications were written several
years ago using Delphi 5, InfoPower 3 and IBO 3.x. On a separate PC,
I provide support for applications written with Delphi 5, InfoPower
3 and IBO 4.x Most of the code in all of these applications has been
stable for some time. Because of the age of my development machines,
I need to transfer my development environment for both old machines
to a new machine. I decided use IBO 4 for all applications. This has
caused a problem. I use the InfoPower component TwwDBLookupCombo at
several places in one application (originally compiled with the IBO 3
library) accessing various different tables to select lookup values
for fields. The query component is TwwIBOQuery which seems to work
fine with the IBO 4 library except in connection with the
TwwDBLookupCombo. Both querys components lined in the
TwwDBLookupCombo are opened when the form is created and no error
occurs at that time. The error does not occur until clicking on the
TwwDBLookupCombo component to open the dropdown list. All of the
TwwDBLookupCombo components fail at this point when using the IBO 4
library but will work without error if the compiled with the IBO 3

The error dialog contains the following text:

ISC ERROR CODE:335544569

Dynamic SQL Error
SQL error code= -104
Token unknown - line 1, char 21


At this point I am not sure how to proceed. Is there any
incompatibility problem using InfoPower 3 and IBO 4? Any suggestions
would be most welcome.
