From: John Smith on 21 Jun 2010 20:44 I'd like to run an alternative to IE in my app and have downloaded the Mozilla control (I'm testing it now). So far it's up to 82MB after an hour and half (120 page requests). Seems to have memory leak issues. http://www.iol.ie/~locka/mozilla/control.htm Does an alternative exist for VB6? Thank you
From: Mayayana on 21 Jun 2010 22:36 I tried that control once, but not in a recent version. Calling it a control was somewhat misleading. It's really pretty much a whole Firefox install. with an added COM interface. As for memory usage, there's been a lot of complaint about that in regard to Firefox generally. I don't know whether it's a problem with all versions, but I've seen discussions where people have complained about it eating up as much memory as is available. I don't think there's any other easy option for VB. All browsers are either IE, Gecko, WebKit, or Opera. It's too complex for someone to just make a control from scratch. | I'd like to run an alternative to IE in my app and have downloaded the | Mozilla control (I'm testing it now).

The program used increasingly more memory as more pages were loaded. Test 2: run program, note initial memory use: IE Browser start 12,968 finish 29,656 total 16,688 Note: Once the program hit 30 MB it just kind of hovered around that number, anywhere between 29 and 30 MB, for all subsequent pages loaded. I'm not aware of any memory settings I could have made to explain this, so maybe there is a memory leak. Mike

I've written a small Binding-Class which (in the same way as the control above) is using the MS-HTML- Interfaces - but bound in this case is a pretty actual (regarding the version) XulRunner-environment. Please do your own tests, if this newer Mozilla- Binaries do work better with regards to Mem- Usage (and caching, which always was a bit more generous than that in IE) ... about a leak I'd only talk, when the increasing mem-usage does *not* stop at some *barrier* of maybe 300MB or so. www.datenhaus.de/Downloads/MozillaRegfree.zip A smaller and lightweight alternative is the Dll (or the Control) at terrainformatica.com - no "full-blown-browser" - but for many purposes more than sufficient.

I ran a test for a few hours, 1 page request every 15 seconds. After about 1000 or so page requests it never went over 80MB. Do you know if it's possible to raise drag events? I'm dragging text from the control to a button above it. Thank you |
