Bugs?
1.DmOpenDatabase(0,lid,dmModeReadOnly | dmModeLeaveOpen);dmModeLeaveOpen flag - does not work anymore for me. The base will be closed on application exit.
2. WinGetBounds(WinGetDisplayWindow(),&display6); wh6 = WinSaveBits(&display6,&winerr); fails for window 320x480 with undocumented error code = 0xBEA0
Neither one sounds like a bug to me, though I could be wrong.
For #1, leaving databases open doesn't really make any sense given that your process is completely torn down when you quit, and the next app gets a clean new one, with none of your open databases and/or leaked memory and/or whatever else. (What are you trying to accomplish by leaving it open?)
For #2: reading from the screen is no longer supported, and besides, WinGetDisplayWindow() isn't actually the display window any more but it just sort of works like it for compatibility with apps using the old drawing model. Plus, saving its bits is unlikely to work right due to the multi-threading nature of drawing: you'll most likely get into problems when someone else has a window up over you. Said differently, you can sometimes read from the window you get when you call WinGetDisplayWindow(), but saving its bits is unlikely to do the right thing so I'm not surprised it fails.
However, returning an undocumented error code would be a bug. How about reporting it at http://www.palmos.com/dev/support/bugs/ so it gets officially logged and addressed?
