PictureBox Yang Diberi Theme/Style - Visual Basic 6

Menjelaskan mengenai cara memberi theme pada object PictureBox - Apabila kita memperhatikan pada posting sebelumnya mengenai ToolBar, TabStrip, TreeView, dan ListView XP Style Tanpa Kode, maka kita akan melihat jelas object TabStrip yang memiliki theme. Nah, object TabStrip tersebut umumnya (tidak selalu) membutuhkan beberapa PictureBox dalam melakukan tugasnya, yang menjadi persoalan sekarang PictureBox tersebut apabila digunakan bersamaan dengan TabStrip akan memiliki perbedaan warna yang mencolok dan ini menyebabkan rancangan GUI yang kurang baik, bagaimana kita mengatasi permasalahan ini? Perhatikan gambar Setting Winrar di bawah ini:

Setidaknya ada dua cara untuk memberi mengatasi masalah PictureBox di atas, pertama memberi theme pada PictureBox, alternatif yang kedua adalah Fake Gradient dengan menyelaraskan warna PictureBox dengan warna TabStrip yang gradient.

Just One Click - LaVolpes Manifest Creator - Tools VB6

Tools VB6 ini - [VB6] XP/Vista/Win7 Manifest Creator - diambil dari sebuah Thread milik LaVolpe yang terdapat di situs VBForums - Setelah beberapa kali mencoba Manifest Creator yang dibuat oleh LaVolpe ternyata hasilnya sangat baik dan memuaskan dengan adanya fitur merger terhadap file resource yang telah ada. Walaupun demikian dalam penggunaannya sedikit merepotkan, terutama jika Anda memiliki banyak project yang harus ditambahkan manifest resouce. Akhirnya saya berinisiatif untuk merubahnya menjadi sebuah Add-Ins, sehingga sekarang memiliki fitur tambahan 'Just One Click'.

Download: LaVolpe's Manifest Creator.

Cara menggunakan:
  1. Ekstrak file, double klik install.bat untuk meregistrasikan komponen
  2. Buka project baru, atau project yang telah Anda buat.
  3. Klik menu Add-Ins >> ManifestCreator >> Create Manifest.
Ucapan terima kasih kepada LaVolpe yang telah membuat tools yang sangat bermanfaat ini.

Software Flying-Fox 1.0 Ini Menggunakan Engine Google Transl

Ini merupakan software Kamus Bahasa Inggris Indonesia, database kamus ini menggunakan google translate, software yang menggunakan database google translate umumnya dinamakan dengan Google Translate Client, mungkin software ini merupakan salah satunya. Mengenai kemampuannya, tentu saja sama dengan Google Translate, Ia dapat menerjemahkan satu kata, satu frase atau satu kalimat. Ia, saya beri nama dengan Flying-Fox 1.0, laksana seekor rubah lincah yang dapat terbang kesana kemari.

Proses Instalasi
Proses instalasi kamus ini sangat sederhana, ia tidak menggunakan InnoSetup Installer, hanya menggunakan file .bat biasa. Sehingga bisa disebut sebagai software semi portable dan bisa dijalankan dari Flashdisk.

Cara Menggunakan
  1. Jalankan Flying-Fox 10
  2. Buka dokumen berbahasa inggris, bisa dari word, wordpad, notepad, browser, dll.
  3. Double klik, untuk menterjemahkan satu kata dan gunakan blok & copy untuk menterjemahkan satu frase atau satu kalimat.

Hanya 1 Baris Untuk Validasi Angka - Visual Basic 6

Di bawah ini merupakan kode untuk memvalidasi angka pada sebuah TextBox, maksudnya pada objek TextBox tersebut hanya memperbolehkan angka saja. Kodenya sangat sederhana, hanya satu baris saja yaitu: KeyAscii = IIf((KeyAscii > 47 And KeyAscii < 58) Or KeyAscii = 8, KeyAscii, 0)

Contoh penggunaan:
Private Sub Text1_KeyPress(KeyAscii As Integer) 
KeyAscii = IIf((KeyAscii > 47 And KeyAscii < 58) Or KeyAscii = 8, KeyAscii, 0)
End Sub
