In most of cases these queries return only several records. From time to time, however, they may return tens of thousands records. All these are then processed in a loop. Because such sit...
I've got a routine that converts a file into a different format and saves it. The original datafiles were numbered, but my routine gives the output a filename based on an internal name found in the original. I tried to batch-run it on a whole directory, and it worked fine until I hit one file whose internal name had a slash in it. Oop...

Note that I need to keep the image transparent as the TImage is being used as an overlay to another image. Some sort of "clear" function for the TImage would be best.

Every once in a while this drives me crazy: I want to move a control to some precise location, WITHOUT any kind of "snapping" -- snap-to-grid, snap-to-guidelines, snap-to-border, etc... and Delphi won't let me. Is there a key combination that one can use while dragging to temporarily turn off any and all "snapping"? I seem to recall it ...
