How to play sound with various path/names?

[petic537]

Hello, I would like to know how play sounds (wav files) with various names in Lazarus.
I have many sounds in my folder (sample1.wav , sample2.wav , sample3.wav). I need to select specific sound to play.

My code example:

path_and_name: string;

path_and_name:='folder\sample' + IntToStr(i) + '.wav';
PlaySound(path_and_name, 0, SND_ASYNC);

This code does not work. Could you please help me to solve this problem...

What kind of error do you get, what os are you using, what Lazarus version, what fpc version,... ?

Maybe, you could begin with the beginning...
Is it working if you use the full path for one wav only ? => something like :

Code: [Select]

PlaySound('C:\MyWavFolder\sample1.wav', 0, SND_ASYNC);

Hello, this code works fine:

Code: [Select]

PlaySound('C:\MyWavFolder\sample1.wav', 0, SND_ASYNC);I have Lazarus 1.2.6 and fpc 2.6.4.

When I try to compile this code:

Code: [Select]

path_and_name:='folder\sample' + IntToStr(i) + '.wav';
PlaySound(path_and_name, 0, SND_ASYNC);
I got the following error message:

unit1.pas(236,20) Error: Incompatible type for arg no. 1: Got "AnsiString", expected "PChar"

=>

PlaySound(PChar(path_and_name), 0, SND_ASYNC);

If you want to play .wav files in both Windows and Linux this page may help:

Thank you. Is there some way how convert string to pchar?

Hum, => Pchar('MyString') must work... => if not, there are problems elsewhere in your code...

So, a good idea is to give us a litle more of your code...
