Multiple program instances

[jak64]

Hello everyone,

I wrote a program that allows me to listen to more than 15,000 songs (Songs, Music, Classical), by being able to choose one or more languages ​​for the songs, by being able to choose the decades (60s, 70s, etc.).

when I use it on a touchscreen computer or a SURFACE tablet, I sometimes launch the program several times at the same time, when I tap on the shortcut!

Is there a way to be able to launch only one instance of my program (just like on VLC where there is a setting that only allows one instance)?

Thank you

You can search for the others.

Thanks for the link, Barry.

Please allow me to add that this method not only prevents multiple instances of an app from launching, but it also relays the parameters of the new launch attempt to the running instance. So, a selected file associated with the app would still execute, but on the running instance.

Thanks BarryG and TI-994A.

As I wrote in another post, I am French and do not speak English (I am 69 years old). I use Google translate to write my posts, that's why I have difficulties searching on the English forum.

Oh, sorry.

Here are some pieces of screen copies of my program to read my music

1) Here, I chose French and English songs from the 60s and 70s and I play them randomly

2) There, I chose music by selecting accordion and trumpet

3) I chose Classical and Beethoven and Mozart

Actually, I can choose whatever I want, for example English songs and music from the 2000s, 2010s and 2020s, etc...
I also manage favorites (I like) and I can copy my favorites (I like) on a USB key or others...

I can also put aside the music that I don't like...

Ps: Before, with pcloud, I was able to put the photos directly in my post, but the site has evolved and apparently, I can't do it anymore, that's why only the links to the screenshots appear...

I recommend imgur.com (in combination with ShareX):

Nice! I wrote a similar Purebasic program years ago
