resopen() help needed.

Hello,

I am drawing bitmaps from an external database, after calling resopen(file). The function always returns zero, but draws the requested bitmap anyway. No problem, except I can't close the database if I wanted, because I don't know the database's id.

Regards,

You can only open a small number of databases at one time. You must match each call to resopen() with a call to resclose().

It sounds like you are probably calling resopen() on the same database multiple times without closing it. This will cause resopen() to eventually fail, but the database is already open so the bitmap is correctly drawn.

Jeremy,

I just started working on this app, and am only opening (1) external database, which contains a few bmps.

Once I am done developing the app I will combine my bitmaps with my final build prc, so I will have no problem with resopen(),(I won't need it, as you know), but I thought it was interesting that the function was returning 0 (for "failed"), not a file index number.

Thanks,

Actually, this is a PocketC bug. resopen() is returning a 0-based id (so 0 could represent failure or the first database). It should return a 1-based id. Thanks for bringing this to my attention.
