Hello,

I have the following problem.
I have a bit string (0 and 1) with date values
How can I check with B4X whether a particular date is contained therein.

this is done via the RegExpObject via Javascript.
https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/RegExp/test

The bit string looks like
011111001111000111100011111001111100111110011111001111100111110011111001111100111110011111001111100111110001111001111100111110011111001111100111010011111000111100111110011111001111100111110011111001111100111110011111001111100111110011111001111100111110011111001111100111110011111001111100111110011111001111100111110011111001011100111110011111001111100111110011111000000000000000000000

With Javascript it looks like

B4X:
            if(/^[0-1]+$/.test(vts)){
                    if(zns[a][5].length>=dayDiff && zns[a][5][dayDiff]==1){
                        hit=true;
                        document.writeln("Datum: ", heute.getDate(), ".", heute.getMonth()+1, "."+heute.getFullYear(), ": ", zns[a][3], " -&gt; ", zns[a][4], "<br />");
                                document.writeln ("<br />");

                    }
                }

(Only a cutout)


can someone help me?
