Memahami License Key Pada Pembuatan OCX - Bisnis OCX

Apabila kita membuat sebuah OCX maka, pada VB6 IDE yaitu pada project properties >> tab General, kita akan mendapati tulisan "Require License Key" (sebelah kiri bawah). Nah, pertanyaannya apa yang terjadi bila checkbox tersebut kita beri centang? Untuk menjawab pertanyaan di atas, sebaiknya Anda membuat sebuah project ocx sederhana kemudian mencentang checkbox bertuliskan "Require License Key" dan mengcompile project tersebut serta memperhatikan pengaruhnya. Apakah ada pengaruhnya? sepertinya atau lebih tepatnya seakan-akan tidak ada.

Perlu diketahui dengan dicentangnya tulisan "Require License Key" maka pada saat mengkompail OCX, VB6 akan secara otomatis membuat satu dari beberapa key baru pada registry, yaitu pada alamat: HKEY\CLASSES_ROOT\Licenses\{OCX GUID Anda}. secara bersamaan VB6 juga mengenerate file yang berektensi *.VBL (bisa Anda buka menggunakan Notepad untuk melihat isinya). Nah, key inilah yang membuat kita bisa menggunakannya pada saat DesignTime.

Untuk memahaminya lebih baik, saya membuat sebuah simulasi penjualan Shadow.OCX. Ikuti langkah-langkah berikut:

• Download terlebih dahulu Amazing Fade Effect - Shadow.OCX. Akan terdapat 3 file di dalamnya:


1. prjAmazingShadow.exe
2. Shadow.ocx
3. Install.bat


• Klik Install.bat untuk meregistrasikan komponen OCX.
• Klik prjAmazingShadow.exe untuk melihat demo shadow.ocx.

Langkah kedua:

• Buat project baru.
• Tambahkan komponen prjShadowCtl (Shadow.OCX).
• Tambahkan ucShadow (Shadow.OCX) ke dalam Form. Apakah Anda bisa melakukannya? tidak, yang ada hanyalah pesan error/pemberitahuan seperti pada gambar di bawah ini:

Keterangan:
Shadow.ocx dibuat oleh Paul Caton. Shadow.ocx merupakan sebuah komponen untuk membuat effect bayangan dan efek fade-in fade-out pada aplikasi, keunggulannya adalah Anda hanya perlu menempelkannya ke dalam Form dan selesai (tanpa membutuhkan kode). Memiliki beberapa properties yang bisa Anda atur untuk disesuaikan dengan selera Anda. Menggunakan teknik SubClassing aman yang diperkenalkan oleh Paul Caton.

Membuat GUI Tanpa Terpengaruh Resolusi Screen - Tips dan Trik VB

Setelah memahami perbedaan .Top, .Left, .Width, .Height dengan .ScaleTop, .ScaleLeft, .ScaleWidth, .ScaleHeight maka kita sekarang melangkah pada bagian selanjutnya mengenai tampilan yang tidak terpengaruh oleh resolusi layar.

Sederhanya agar sebuah form memiliki ukuran relatif sama adalah membagi ukurannya lebar dan tinggi berdasarkan prosentase. Perhatikan 2 baris kode di bawah:

Option Explicit 
 
Private Sub Form_Resize() 
    With Form1 
        .Left = 0 
        .Top = 0 
        .Height = Screen.Height 
        .Width = Screen.Width 
    End With 
End Sub 

Kode di atas akan membuat sebuah form memiliki ukuran sama dengan tinggi dan lebar layar, berapapun resolusinya. Maka kode di bawah akan membuat form memiliki ukuran 1/2 dari ukuran layar baik tinggi maupun lebarnya, berapapun resolusi layar yang Anda setting.

Option Explicit 
 
Private Sub Form_Resize() 
    With Form1 
        .Left = 0 
        .Top = 0 
        .Height = (Screen.Height * 0.5) 'Ini akan membuat tinggi Form setengahnya dari layar 
        .Width = (Screen.Width * 0.5) 'Ini akan membuat lebar Form setengahnya dari layar. 
    End With 
End Sub 

Sekarang coba Anda rubah resolusi layar ke posisi paling ektrim terbesar atau ke posisi ektrim terendah, Apakah tinggi dan lebar Form tersebut berubah? tidak, dia tetap setengahnya dari layar. Lalu apa yang harus Anda lakukan selanjutnya, melakukan resize terhadap seluruh control (CommandButton, TextBox, Label, dan lain-lain. Nah, bagaimana caranya?

Memasukan Gambar ke Dalam OCX - Teka-Teki VB6

Setelah teka-teki ShellContextMenu (untuk mengintegrasikan aplikasi dengan Windows Explorer), sekarang saya memiliki teka-teki sederhana yang lain, yakni mengenai cara memasukan gambar ke dalam .OCX (default VB atau third party).

Seperti yang kita ketahui, untuk membuat generator code yang baik salah satunya kita harus dapat memasukan gambar ke dalam .OCX yang kita butuhkan. Untuk .OCXnya saya menggunakan ImageList saja (bukan third party, pada dasarnya ia bisa digunakan untuk segala macam .OCX yang membutuhkan gambar).

Teka-tekinya sederhana, hanya memasukan gambar ke dalam objek ImageList, tentu Anda dapat memecahkannya. Apabila Anda menyukai teka-tekinya silakan download pada link di bawah ini:
