Hello,
my apps grabs about 2000 bitmaps from a sql database and shows them in a scrollview with imageviews.
Collecting these 2000 bitmaps needs a little bit time. On slower devices, the message "application not responding" appears.
My question is: How an I avoid that message?
- Should I use a service to collect the 2000 bitmaps?
- Should I use a thread?
- Would "DoEvents" help?
I tried to use sql.begintransaction .... sql.endtransaction, but I'm always running in an error message ("cursor couldn't initalize" or something like that), so I didn't use sql.begintransaction.
Are there any general hints how to avoid "application not responding" messages?
Best regards,
Carsten
