MEMBUAT APLIKASI PAINT SEDERHANA



Bagaimana sih cara membuat aplikasi paint sederhana.
dibawah ini akan di jelaskan bagaimana cara membuat aplikasi sederhana menggunakan bahasa pemograman c# dengan Windows Form Application di visual studio 2012

ini cara nya, selahkan diikuti dan di kembangkan lagi
1. buka Visual studio 2012


2. pilih new project lalu Windows Forms Application, kasih judul dan oke


3. ambil tools apa saja yang akan kita gunakan di toolbox lalu tarik ke form1 anda


4. desain form1 seperti ini



“Sumbu x” adalah garis horizontal dan “sumbu y” adalah garis vertikal,
“panjang” adalah panjang garis yang telah kita buat.


untuk warna kita memakai button dan di beri warna sesuai nama dengan mengubah properties backimage.
sedangkan line, elips, rectangle,triangle dan clear, kita beri gambar yang dimasukkan dari background image.


5. jika sudah masukkan program ini

    }
}
   
6. jika sudah lakukan running program


ini adalah hasilnya jika sudah berhasil sob

demikian tutorial program c# untuk membuat paint sederhana di visual studio menggunakan windows form application.
semoga bermanfaat untuk kita semua.
