For Experts: Creating a form with Rollback capability

Zone: Microsoft Access Database

Tags: Microsoft, Access

Hello experts,

This is not a question, but rather a open thread for technical discussion about transactions. However, there is a challenge for the points.

Your mission, should you choose to accept it, will be to create a form with rollback capability. It should display an editable subform showing some data, and three buttons: [OK], [Apply], and [Cancel]. When pressing [Cancel] or closing the form with [x], any editing done in the subform since the last [Apply] should be undone. This included record deletion, of course.

I suggest we do not start exchanging attached databases, as this can be achieved in under 30 lines of code.

Cheers all!

Markus

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

wow ... what happened a post I made several days ago? Weird!

Well, what is said was ... I did try this out (downloaded the mdb) and it IS very cool ... and in the final analysis - quite simple (not to down play the elegance of it). It would require a bit of error trapping, but hey ... it's a cool concept.

! I even use it from time to time"

Actually, can we give a few real world examples where this might be used ?
