Dot Net / COM Interop Issues

Just overcome an extremely challenging problem we've been having. Our COM application was calling out to a dot net assembly through COM Interop and when the dot net assembly returned a response the process would get terminated... no friendly output, error messages, or log entries - just dead.

The solution was to totally REMOVE the Dot Net 2.0 framework and re-install. We tried a REPAIR first but that didn't seem to do anything.

It's worth mentioning that the problem didn't occur when calling into the dot net assembly but rather when it returned something to VB6... very strange.

Anyway, strike another issue off the project wall. Time to move back on to Prospecting!

Addendum> Apparently this issue is caused by one of the Dot Net 2.0 Security Updates from Windows Update! For now we're avoiding this patch.

Aristo Vehicle Management (Alpha)

Yesterday we installed Aristo Vehicle Managment into Alpha at a dealership here in Calgary. We'll be working with them over the next few weeks to iron out any wrinkles as we continue to push forward on our Aristo Front End project. Couple highlights...

A true common vehicle file (which provides for some extremely powerful and concise search capabilities)...

The tree in the top-right corner allows searching by vehicle type according to Make, Model, and Trim level. This search is hierarchical so you can search for any type of unit. We also support search for specific unit types, options, pricing, or even across vehicles that have been sold to customers for potential lease returns.

 

We've also completed an integrated vehicle screen accessible from all modules. This screen allows all departments to have the same view of a vehicle complete with all vehicle history.

This common UI means that given the right security a user can review and edit any information of a vehicle by selecting the correct View in the top right hand corner. Vehicle history is reported down the right side of the screen and allows immediate access to any "event" (such as a Repair Order or Sales Rep Hold) which has affected this unit.

 

This project will be the foundation for our further work on Front End and provides a major step forward on the Aristo Front End project.
