Hi Everyone!
I am using Lazarus 1.8 on Linux Mint. I would like to use the
Windows.Beep( Freq, Duration) function, or (if not available)
SysUtils.Beep subprograms.
Simplest problem. SysUtils.Beep compiles and links but is silent.
Slightly more difficult (according to StackOverflow)
I should be able to insert (manually) Windows in the uses clause, then
call the windows.beep( f, d) function, but fcp can't find Windows even
though there are several windows.pp files in the fpcscr directories.
Failing that, the article says:
|functionBeep(dwFreq,dwDuration:DWORD):BOOL;stdcall;external'kernel32.dll';|
should work, but it causes a linker error after compilation. I don't
have lernel32.dll on my Linux system.
A long time ago, I used the Windows.Beep (on windows) to produce Morse
Code error messages while debugging visual components. I would like
to do that now if possible, but on Linux.
Any suggestions would be appreciated.
Thanks,
Don Ziesig
