Steps to Create a Barcode Generator

Step 1: Create ASP.NET Core Web App (Razor Pages)

Creating an ASP.NET Core Web App with Razor Pages in Visual Studio is straightforward. This guide will help you set up your project from scratch:

1. Open Visual Studio: Start Visual Studio. On the start window, select "Create a new project" to begin the process of setting up your new web application.
2. Choose Project Type: In the "Create a new project" window, select "ASP.NET Core Web App" from the list of project templates. Then, click "Next" to proceed.

3. Configure Your Project: You'll now be prompted to configure your new project.
   • Enter a "Project Name" for your web application.
   • Choose a suitable "Location" on your computer where the project files will be stored.
   • Optionally, adjust the "Solution name".
   • Click "Next" to continue.

4. Set Up Project Details: In the "Additional Information" window, make sure to:
   • Select the appropriate version of .NET.
   • Verify that "Configure for HTTPS" is checked.
   • Click "Create" to initiate the creation of your new Razor Pages web application.

Step 2: Install the IronBarcode Library

To install IronBarcode using the NuGet Package Manager in Visual Studio:

1. Access the NuGet Package Manager: Right-click on your project name in the Solution Explorer pane. Select "Manage NuGet Packages…" to open the NuGet Package Manager tab.
2. Search for IronBarcode: In the "Browse" tab, type "IronBarcode" to find the library.
3. Install IronBarcode: Select "IronBarCode" and click "Install". Review any dependencies and license agreements, then accept to proceed.

Step 3: Design the UI

Enhance the Index page by editing the index.cshtml file. Apply custom styling:

<style>
    body {
        font-family: 'Poppins', sans-serif;
    }
    /* More CSS styles omitted for brevity */
</style>

<style>
    body {
        font-family: 'Poppins', sans-serif;
    }
    /* More CSS styles omitted for brevity */
</style>

Adding a Welcome Message:

<h1 class="text-center mb-4" style="color:#004b9b">Welcome to Barcode Generator</h1>
<div class="svg-container text-center">
    <img src="~/images/logo.svg" class="barcode-logo" alt="Barcode" />
</div>

<h1 class="text-center mb-4" style="color:#004b9b">Welcome to Barcode Generator</h1>
<div class="svg-container text-center">
    <img src="~/images/logo.svg" class="barcode-logo" alt="Barcode" />
</div>

Structuring the Main Content:

<div class="container">
    <div class="row justify-content-center">
        <!-- Form and Image Column will go here -->
    </div>
</div>

<div class="container">
    <div class="row justify-content-center">
        <!-- Form and Image Column will go here -->
    </div>
</div>

Design Input Form:

Include the form to collect user input for barcode generation:

<div class="col-md-6 divider col-padding">
    <form method="post" enctype="multipart/form-data">
        <!-- Form elements omitted for brevity -->
        <button type="submit" asp-page-handler="Upload" class="btn btn-primary btn-block">Generate Barcode</button>
    </form>
    <div id="messageContainer">
        <span id="message" style="color:green;">@Html.Raw(Model.Message)</span>
    </div>
</div>

<div class="col-md-6 divider col-padding">
    <form method="post" enctype="multipart/form-data">
        <!-- Form elements omitted for brevity -->
        <button type="submit" asp-page-handler="Upload" class="btn btn-primary btn-block">Generate Barcode</button>
    </form>
    <div id="messageContainer">
        <span id="message" style="color:green;">@Html.Raw(Model.Message)</span>
    </div>
</div>

Image Column:

For displaying and downloading the generated barcode:

<div class="col-md-6 image-padding">
    <div id="imageContainer">
        <!-- Image and download button elements omitted for brevity -->
    </div>
</div>

<div class="col-md-6 image-padding">
    <div id="imageContainer">
        <!-- Image and download button elements omitted for brevity -->
    </div>
</div>

Scripts:

Add functionality to handle input and download actions using jQuery:

@section Scripts {
    <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
    <script>
        $(document).ready(function () {
            // jQuery code omitted for brevity
        });
    </script>
}

@section Scripts {
    <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
    <script>
        $(document).ready(function () {
            // jQuery code omitted for brevity
        });
    </script>
}

Step 4: Writing Functional Code

Define Color:

At the top of your index.cshtml file, add:

using Color = IronSoftware.Drawing.Color;

using Color = IronSoftware.Drawing.Color;

Barcode Colors Enum:

Define available colors for barcodes:

public enum BarcodeColors
{
    AliceBlue,
    AntiqueWhite,
    Aqua,
    Aquamarine,
    Azure,
    Beige,
    Bisque
    // And others...
}

public enum BarcodeColors
{
    AliceBlue,
    AntiqueWhite,
    Aqua,
    Aquamarine,
    Azure,
    Beige,
    Bisque
    // And others...
}

Public Enum BarcodeColors
	AliceBlue
	AntiqueWhite
	Aqua
	Aquamarine
	Azure
	Beige
	Bisque
	' And others...
End Enum

Barcode Types Enum:

Define available types of barcodes:

public enum BarcodeTypes
{
    Aztec,
    Codabar,
    // Other barcode types...
}

public enum BarcodeTypes
{
    Aztec,
    Codabar,
    // Other barcode types...
}

Public Enum BarcodeTypes
	Aztec
	Codabar
	' Other barcode types...
End Enum

Helper Functions:

Convert enums to color and barcode encoding:

private Color EnumToColor(BarcodeColors colorEnum) { /* Conversion logic */ }
private BarcodeWriterEncoding GetBarcodeEncoding(BarcodeTypes barcodeType) { /* Encoding logic */ }

private Color EnumToColor(BarcodeColors colorEnum) { /* Conversion logic */ }
private BarcodeWriterEncoding GetBarcodeEncoding(BarcodeTypes barcodeType) { /* Encoding logic */ }

Private Function EnumToColor(ByVal colorEnum As BarcodeColors) As Color
End Function
Private Function GetBarcodeEncoding(ByVal barcodeType As BarcodeTypes) As BarcodeWriterEncoding
End Function

OnPostUpload Function:

Handle form submission for barcode generation:

public JsonResult OnPostUpload(string barcodeText, string barcodeType, int? maxWidth, int? maxHeight, string barcodeColor)
{
    // Function logic...
}

public JsonResult OnPostUpload(string barcodeText, string barcodeType, int? maxWidth, int? maxHeight, string barcodeColor)
{
    // Function logic...
}

Public Function OnPostUpload(ByVal barcodeText As String, ByVal barcodeType As String, ByVal maxWidth? As Integer, ByVal maxHeight? As Integer, ByVal barcodeColor As String) As JsonResult
	' Function logic...
End Function

Layout Editing:

Edit \_Layout.cshtml for a minimalist design:

<!DOCTYPE html>
<html lang="en">
<head>
    <!-- Head contents omitted for brevity -->
</head>
<body>
    <div class="container">
        <main role="main" class="pb-3">
            @RenderBody()
        </main>
    </div>
    <!-- Scripts inclusion omitted for brevity -->
</body>
</html>
