That's why Winsoft has developed Barcode for FireMonkey 3.7, a barcode component for Delphi and C++ Builder that allows developers to easily generate and decode barcodes in their FireMonkey applications. Barcode for FireMonkey 3.7 is based on Zint, an open-source barcode encoding library that supports over 50 barcode types, including QR Code, Data Matrix, Aztec Code, Code 128, EAN, UPC, and more. Barcode for FireMonkey 3.7 supports Windows, MacOS, iOS, and Android platforms, and provides a simple and flexible interface to customize the barcode appearance and properties.

How to use Barcode for FireMonkey 3.7

To use Barcode for FireMonkey 3.7 in your application, you need to add the FBarcode unit to the uses clause of your unit. Then, you can create a TBarcode object and assign the barcode type (Symbology), the input text (InputText), and other optional parameters (such as ForeColor, BackColor, BorderWidth, Scale, Rotation, etc.) to it. You can also use the OutputOptions property to control the barcode output options, such as showing or hiding the text, drawing a box or a border around the barcode, using small or bold text, etc.

After setting up the TBarcode object, you can use the Bitmap property to get the barcode image as a TBitmap object. You can then assign this bitmap to any TImage or TCanvas object in your application to display or print the barcode. Alternatively, you can use the SaveToFile method to save the barcode image as a PNG file.

To decode a barcode image, you need to use the TBarcodeDecoder object and its Decode method. The Decode method takes a TBitmap object as an input and returns an array of TDecodeResult objects as an output. Each TDecodeResult object contains the decoded text (Text) and the barcode type (FormatName) of the barcode image. You can then use this information in your application logic or display it to the user.

Example code

The following code snippet shows how to generate a QR Code with Barcode for FireMonkey 3.7 and display it in a TImage object:

uses FBarcode; ... begin //Assign Barcode Type FBarcode1.Symbology := TSymbology.syQRCode; //Assign Barcode Value FBarcode1.InputText := 'QR-12345'; //Generate Barcode and Display into Image ImageBarcode.Bitmap.Assign(FBarcode1.Bitmap); end;

The following code snippet shows how to decode a barcode image with Barcode for FireMonkey 3.7 and display the result in a TMemo object:

uses FBarcode; ... var Barcodes: TDecodeResults; I: Integer; begin with TBarcodeDecoder.Create do try //Decode Barcode Image Barcodes := Decode(ImageControl.Bitmap); //Display Decoded Results Memo.Lines.Clear; for I := 0 to Length(Barcodes) - 1 do Memo.Lines.Append(Barcodes[I].FormatName + ': ' + Barcodes[I].Text); finally Free; end; end;

Conclusion

Barcode for FireMonkey 3.7 is a powerful and easy-to-use barcode component for Delphi and C++ Builder that enables developers to create and scan barcodes in their cross-platform applications. It supports over 50 barcode types and provides a flexible interface to customize the barcode output. It is based on Zint, an open-source barcode encoding library that is constantly updated and improved.

How to use Barcode for FireMonkey 3.7 with FireDAC

FireDAC is a cross-platform data access library for Delphi and C++ Builder that provides high performance, easy-to-use, and unified access to various database systems, such as SQLite, MySQL, Oracle, SQL Server, etc. FireDAC allows developers to work with data using common components and methods, regardless of the underlying database engine.

One of the features of FireDAC is the ability to store and retrieve binary data, such as images, files, or blobs, from a database using the TFDBlobStream class. This class provides a stream interface to read and write binary data from a database field. Using this class, we can store and retrieve barcode images generated by Barcode for FireMonkey 3.7 in a database table.

To demonstrate this feature, we will use a SQLite database with a table called Barcodes that has two fields: ID (integer) and Image (blob). We will use the following code to create and populate this table:

uses FBarcode, FireDAC.Comp.Client, FireDAC.Stan.Def; ... var FDConnection: TFDConnection; FDQuery: TFDQuery; FBarcode: TBarcode; BlobStream: TFDBlobStream; I: Integer; begin //Create and open connection to SQLite database FDConnection := TFDConnection.Create(nil); FDConnection.Params.DriverID := 'SQLite'; FDConnection.Params.Database := 'Barcodes.db'; FDConnection.Open; //Create Barcodes table FDQuery := TFDQuery.Create(nil); FDQuery.Connection := FDConnection; FDQuery.ExecSQL('CREATE TABLE IF NOT EXISTS Barcodes (ID INTEGER PRIMARY KEY, Image BLOB)'); //Create barcode object FBarcode := TBarcode.Create(nil); FBarcode.Symbology := TSymbology.syCode128; //Insert barcode images into Barcodes table for I := 1 to 10 do begin //Assign barcode value FBarcode.InputText := 'BAR-' + IntToStr(I); //Create blob stream BlobStream := TFDBlobStream.Create(nil); try //Save barcode image to blob stream FBarcode.SaveToStream(BlobStream); //Insert blob stream into Barcodes table FDQuery.SQL.Text := 'INSERT INTO Barcodes (Image) VALUES (:Image)'; FDQuery.ParamByName('Image').AsStream := BlobStream; FDQuery.ExecSQL; finally BlobStream.Free; end; end; end;

The above code will create a SQLite database file called Barcodes.db in the application folder and insert ten barcode images into the Barcodes table. Each barcode image will have a different value from BAR-1 to BAR-10.

To retrieve the barcode images from the Barcodes table and display them in a TListView object, we can use the following code:

uses FBarcode, FireDAC.Comp.Client, FireDAC.Stan.Def; ... var FDConnection: TFDConnection; FDQuery: TFDQuery; FBarcode: TBarcode; BlobStream: TFDBlobStream; begin //Create and open connection to SQLite database FDConnection := TFDConnection.Create(nil); FDConnection.Params.DriverID := 'SQLite'; FDConnection.Params.Database := 'Barcodes.db'; FDConnection.Open; //Create query to select all records from Barcodes table FDQuery := TFDQuery.Create(nil); FDQuery.Connection := FDConnection; FDQuery.SQL.Text := 'SELECT * FROM Barcodes'; //Open query and loop through records FDQuery.Open; while not FDQuery.Eof do begin //Create blob stream BlobStream := TFDBlobStream.Create(nil); try //Load blob stream from Barcodes table BlobStream.LoadFromField(FDQuery.FieldByName('Image')); //Create barcode object FBarcode := TBarcode.Create(nil); //Load barcode image from blob stream FBarcode.LoadFromStream(BlobStream); //Add barcode image and value to list view with ListView.Items.Add do begin Text := FBarcode.InputText; //barcode value Bitmap.Assign(FBarcode.Bitmap); //barcode image end; finally BlobStream.Free; end; //Move to next record FDQuery.Next; end; end;

The above code will display the barcode images and values from the Barcodes table in a list view. The list view will look something like this:

As you can see, using Barcode for FireMonkey 3.7 with FireDAC is very easy and convenient. You can store and retrieve barcode images from any database system that FireDAC supports, and use them in your cross-platform applications.

How to use Barcode for FireMonkey 3.7 with LiveBindings

LiveBindings is a data binding framework for Delphi and C++ Builder that allows developers to connect data sources and controls using expressions and designers. LiveBindings can be used to create data-driven applications that automatically update the user interface when the data changes, or vice versa.

One of the advantages of LiveBindings is that it can work with any type of data source and control, including custom components. This means that we can use LiveBindings to bind barcode properties to data sources and controls using Barcode for FireMonkey 3.7. For example, we can bind the InputText property of a TBarcode object to a TEdit control, so that the barcode image changes when the user enters a new value in the edit control, or vice versa.

To demonstrate this feature, we will use a simple application that has a TEdit control, a TImage control, and a TBarcode object on a form. We will use the LiveBindings Designer to create a bidirectional binding between the InputText property of the TBarcode object and the Text property of the TEdit control. We will also create a unidirectional binding between the Bitmap property of the TBarcode object and the Bitmap property of the TImage control. The LiveBindings Designer will look something like this:

The above bindings will create the following effects:

• When the user enters a new value in the edit control, the barcode image will update accordingly.

• When the user scans a barcode image using a barcode scanner or a camera, and the decoded value is sent to the edit control, the barcode image will update accordingly.

• When the user clicks on the image control, a dialog box will appear that allows the user to load an image file from disk. If the image file contains a barcode image, it will be decoded and displayed in the edit control.

The application will look something like this:

As you can see, using Barcode for FireMonkey 3.7 with LiveBindings is very easy and powerful. You can bind barcode properties to any data source or control that supports LiveBindings, and create dynamic and interactive applications.
