Recreating views...
-
To increase usability. I once had an MFC app that ran on an 80 MHz CE 2.11 device. It had about 30
CView-based classes and would take an unreasonable number of seconds to launch. So instead of creating all of the views at initialization, I created and destroyed views as the user navigated through the program. -
hi, i have a MFC Explorer style application with doc/view architecture.... is it possible to delete (free or release) current left and right views and recreate them at a particular instant (e.g. when a button is clicked.)?

I guess you didn't think I knew the answer to the question, but I did as I have done the same thing some years ago. I wanted to be sure he needed it before I went to the trouble of digging up any help for the issue. Also I try not to help people produce the wrong solution for the problem they are solving.

ok, i'm actually i'm working on a Windows Explorer like application. The web browser control is used in right pane. Which emulates the list view exactly similar to that in Windows Explorer. But, when some drive/folder selected in it, that folder is actually marked as 'in use' by Windows (i.e. some file handles must be kept open by Windows). Even SetCurrentDirectory() doesn't works. Now, I think that whenever a new drive is to be shown, i can destroy the old view and recreate new one...

It's definitely possible. If you provide your email address, I'll send you some VC6 code I have.

Couldn't you just hide them until you want to use them again? Or is it a necessity to free/release them? ---modified I saw your post to led mike, makes sense now :-O

it's certainly necessary to release them and to recreate them... do u know how to do that?

Many of them don't pass the test.

I guess I don't understand what you're asking for. When the user selects a folder in the left pane, files (and sub-folders) show up in the right pane. Simply doing a FileFind on *.* to populate the right pane should be sufficient, and whether those files/folders are "in use by windows" is irrelevant.

This shows the exact ListView similar to what we see in Windows Explorer. I even get bonus items like Task Lists, Contextual Menus etc. But it can be using notification functions to know about changes in that folder and also displays 'Details', such as preview of images etc., and for that opening files in necessary... i think.

You, sir, are a beautiful person and your holistic approach to righting the world's ills should be celebrated. All apologies.
