Ukwahlulahlula iSicombululo
Isisombululo sethu siqala nge Inkqubo yeWindows yeWindows indawo yegama, equka uluhlu lweentlobo zokwenza ujongano lomsebenzisi womzobo nokulawula ukuziphatha kwabo. Phakathi kwezi ntlobo yi Label iklasi, emele ileyibhile esemgangathweni yeWindows.
Iklasi yethu yeForm1 igcina umzekelo omnye weLeyibhile, ileyibhile1.

Ipropathi ye-ForeColor ibhekiselele kumbala ongaphambili wolawulo, othi kwiLeyibhile, ichaphazele umbala wokubhaliweyo.
Lo mzekelo weLeyibhile wongezwa kuLawulo lwefom – ingqokelela yalo lonke ulawulo oluqulethwe kwifomu.
Okokugqibela, ngaphakathi kwendlela ephambili, siqalisa iFomu1 yethu kwaye siqhube isicelo.
ISixokelelwano.IWindows.IiFomu zeNdawo yegama kunye neKlasi yeLeyibhile
Inikwe indima yayo ebalulekileyo ekuphuhliseni usetyenziso olusekwe kwiWindows, ukuqonda i Inkqubo yeWindows yeWindows indawo yegama ibalulekile kuyo nayiphi na i C# umdwelisi. Ibonelela ngeendlela ezahlukeneyo zolawulo njengamaqhosha, iibhokisi zokubhaliweyo, kunye neelebhile phakathi kwezinye.

Indlela ye-Application.Run kumsebenzi wethu oPhambili yi-injini enika amandla kwifomu yethu, ithatha umzekelo wethu weFomu1 kwaye uyiqhube njengesicelo. Oku Isicelo.Baleka linyathelo lokugqibela lokuzisa iFomu yethu, kunye neleyibhile yayo enemibala, ebomini.
Siyathemba ukuba eli nqaku likunike ukuqonda okuqinileyo malunga nendlela yokutshintsha i-forecolor yeleyibhile kwi-C # kunye nendima ebalulekileyo ye-System.Windows.Forms namespace, kunye neklasi yeLeyibhile, idlala kumsebenzi onjalo. Ikhowudi yolonwabo!
