Odpověď na: Uchování hodnoty proměnné
omlouvat se vubec nemusis. nikdo z nas nezna vsechno a kazdy nejak zacinal.
Kdyz vkladas kod pouzivej parove znacky „code“ (tlacitko CODE) pred a za kodem. uchova si formatovani. trochu jsem ti to prekopal:
– zrusil duplicitni vypocty
– odstranil zobrazovani obrazovek jen pri stisku tlacitka (funkce zobraz() )
– presunul promennou tlacitko
– naformatoval podle se abych se v tom vyznal.
– …
vsechny zmeny mam pod revizi “ #1 “ takze ji muzes v pohode dohledat
Vyzkousej to a uvidis. ja nema jak to vyzkouset a stavet se mi to vazne nechce 🙂 :
