>A pre-existing VFP application built entirely in VFP with no framework or third party components at all. Typically, frameworks are used entirely for new development or in other words, all new apps created from scratch. There is typically no way to bring any of the classes/controls from a framework into an existing app and have them function correctly without the underlying framework dependencies bomb. I was hoping one of the frameworks out there allowed this.

Hi Tracy,

I had such experience with one of the applications, which I inherited from my colleague. That application was written in the framework, which we didn't use for all other applications (we use self-made framework in the organization, where I worked). In my opinion, it had lots of overhead and I didn't really like that framework, though I did check classes and code behind. So, in about two or three full days of work I was able to tranverse from one framework to another (the one we use) for that application. I also found, that the developer didn't use own created classes, but preferred to repeat same code over and over in the form. So, I made few textboxes classes instead... After all the work, I've done, the application very slightly reminded the original. I also added a new mode to this application with my own forms, classes, etc.

It took quite an amount of time to make all the changes. Also we don't use n-tier concept in that organization (pity), so all applications are monolitic...

===================
I've written this and then remembered, that I had two more applications from another developer, which I changed from MS framework to our self-made framework. But it was long time ago and as I recall, was not really hard.
