Question:
I have a simple animation on a form created by turning bitmaps on and off in sequence. How can I pause between frames? There is no wait or pause command.

I can create a nested for-loop but this seems a clumsy way to solve the problem. There must be a simple way to delay the program for an exact number of seconds. Any ideas?

Answer:
If you’re using Delphi 2.0, use the Sleep procedure. Look it up in thehelp file. If you’re using Delphi 1.0, you can use the procedure below:

procedure Sleep(SleepSecs : Integer);var  StartValue : LongInt;begin  {Initialize vars}  StartValue    := GetTickCount; {Get value of current milliseconds elapsed}  While ((GetTickCount – StartValue) <= (SleepSecs * 1000)) do    Application.ProcessMessages;end;

It does the same thing as Delphi 2.0’s sleep, though D2’s Sleep offers abetter time resolution by using milliseconds as its input.
