DataSet to PDF

Creating a PDF with information from a DataSet record seems like a very simple task. But that task just got easier. DataSet PDF has two functions for this, namely ToPDFStream and ToPDFFile. Let's look at the use of the functions:

begin
  qrySamples.ToPDFStream(''); // Create a TStream
  qrySamples.ToPDFFile('c:\temp\file.pdf'); // Create a PDF File 
end;

Parameters function ToPDFStream(const AFieldStructure: String; const ADownloadFile: Boolean = True; const AChildRecords: Boolean = True): TStream;

• AFieldStructure - File with parameters for each field;
• ADownloadFile - Indicates Content-Disposition of PDF(inline/attachment);
• AChildRecords -Indicates whether or not to export child records (via master detail or TDataSetField).;

procedure ToPDFFile(const AFileName: String; const AFieldStructure: String = ''; const AChildRecords: Boolean = True);

• AFileName - Name of PDF file;
• AFieldStructure - File with parameters for each field;
• AChildRecords - Indicates whether or not to export child records (via master detail or TDataSetField).;

Field Structure Example

	{
		"fieldName": "name",

		"displayLabel": "Name",
		"visible": true
	},    
	{
		"fieldName": "e_mail",

		"displayLabel": "E-mail",
		"visible": true
	},    
	{
