Cara Membuat Program Barcode Dengan Visual Basic

Setelah kemarin kita berkenalan dengan dengan program Visual Basic, (baca: Mengenal Program Microsoft Visual Basic) kini saatnya kita mulai membuka dan mengenali tools-tools yang ada di dalam program VB ini. Untuk memulainya, kamu harus menginstall program Microsoft Visual Basic terlebih dahulu di komputer kamu. Kamu bisa mendownload aplikasinya pada link berikut (link). Berikut ini adalah cara membuat program yang menampilkan nama dengan cara mengklik tombol atau button dan nama tersebut akan muncul menggunakan label. Membuat program ini menggunakan metode drag and drop dan juga koding untuk menerapkan action dari toolbox yang telah terpasang di form. Langkah-Langkah 1. Langkah pertama buka aplikasi Visual Studio, buat projek baru dengan cara memilih menu.

I am attempting to take a string and convert it into a code 128 barcode in vb.net. I am a novice programmer and was wondering what some people thought would be the best design practices for accomplishing this.

A simple google search has yielded a few seemingly free solutions to this.http://www.onbarcode.com/vb_net/code-128-generator.htmlfor example

I could also attempt to do this myself, but I'm not sure the exact method of converting strings into barcodes.I am going to keep looking into this but if someone knew this off the top of their head already it could save me some time.

Thanks in advance

If you don't want to write any code for string conversion in barcode and don't want to buy an external component, you can use the ItextSharp library ( http://sourceforge.net/projects/itextsharp/ ) which is in my opinion the simplest way to achieve your goal. You can find several resources online and on stackoverflow too for itextsharp, mostly in c# but also vb.net.

for barcode generation vb.net code you can have a look here:http://professionalaspnet.com/archive/2008/11/09/A-Quick-and-Dirty-Bar-Code-Image-httpHandler.aspx

Have a look at the following codeproject page - Barcode Image Generation Library

This allows you to generate a barcode image in your desired format from a string.

It should be enough to get you started

The following examples are taken from

You need to question your goal. That answer will drive your methodology.

Rapid development and completion
Learning experience
Cheap / free (sweat-equity excluded)

Your google link shows a product that displays sample code on that very page. What's wrong with that?

What is your target output? A report object, or will you print directly to the printer/label?

You can generate and output the code128 images in VB programming with this code . Refer to the following Visual Basic sample code,you can try to generate code128 in vb.net.

Cara Membuat Program Barcode Dengan Visual Basic

Kode di bawah ini akan menunjukkan cara untuk input data ke dalam kotak teks dan mendapatkan barcode dari gambar itu. Anda juga akan mempelajari bagaimana untuk bekerja dengan clipboard checksum dan kontrol.
Untuk menggunakan, baru memulai Visual Basic Proyek, menambahkan formulir untuk proyek dan paste kode di bawah ini ke dalamnya. Anda akan memiliki visual untuk membuat kotak (qty4), tombol perintah, frame (qty2), label, tombol pilihan (qty4), gambar kotak (qty2) dan kotak teks.

Berikut tampilan preview dari program barcode maker yang kita akan buat.Untuk desain anda bisa membuat sesuai dengan
