Examples

Create If Field in C++

#include "pch.h"
using namespace Spire::Doc;

int main() {
	wstring output_path = OUTPUTPATH;
	wstring outputFile = output_path + L"CreateIFField.docx";

	//Create Word document.
	Document* document = new Document();

	//Add a new section.
	Section* section = document->AddSection();

	//Add a new paragraph.
	Paragraph* paragraph = section->AddParagraph();

	// Define a method of creating an IF Field.
	CreateIfField(document, paragraph);

	//Define merged data.
	vector<LPCWSTR_S> fieldName = { L"Count" };
	vector<LPCWSTR_S> fieldValue = { L"2" };

	//Merge data into the IF Field.
	document->GetMailMerge()->Execute(fieldName, fieldValue);

	//Update all fields in the document.
	document->SetIsUpdateFields(true);

	//Save to file.
	document->SaveToFile(outputFile.c_str(), FileFormat::Docx2013);
	document->Close();
	delete document;

}

void CreateIfField(Document* document, Paragraph* paragraph)
{
	IfField* ifField = new IfField(document);
	ifField->SetType(FieldType::FieldIf);
	ifField->SetCode(L"IF ");

	paragraph->GetItems()->Add(ifField);
	paragraph->AppendField(L"Count", FieldType::FieldMergeField);
	paragraph->AppendText(L" > ");
	paragraph->AppendText(L"\"100\" ");
	paragraph->AppendText(L"\"Thanks\" ");
	paragraph->AppendText(L"\"The minimum order is 100 units\"");

	ParagraphBase* end = document->CreateParagraphItem(ParagraphItemType::FieldMark);
	FieldMark* fm = dynamic_cast<FieldMark*>(end);
	fm->SetType(FieldMarkType::FieldEnd);
	paragraph->GetItems()->Add(end);
	ifField->SetEnd(dynamic_cast<FieldMark*>(end));
}

Convert Word to PDF in C++

#include "pch.h"
using namespace Spire::Doc;

int main() {
	wstring input_path = DATAPATH;
	wstring inputFile = input_path + L"ConvertedTemplate.docx";
	wstring output_path = OUTPUTPATH;
	wstring outputFile = output_path + L"ToPDF.pdf";

	//Create word document
	Document* document = new Document();
	document->LoadFromFile(inputFile.c_str());

	//Save the document to a PDF file.
	document->SaveToFile(outputFile.c_str(), FileFormat::PDF);
	document->Close();
	delete document;
}

Convert Word to Images in C++

#include "pch.h"
using namespace Spire::Doc;


int main() {
	wstring input_path = DATAPATH;
	wstring inputFile = input_path + L"ConvertedTemplate.docx";
	wstring output_path = OUTPUTPATH;
	wstring outputFile = output_path + L"ToImage.png";

	//Create word document
	Document* document = new Document();
	document->LoadFromFile(inputFile.c_str());

	//Save doc file.
	Stream* imageStream = document->SaveToImages(0, ImageFormat::GetPng());
	imageStream->Save(outputFile.c_str());
	document->Close();
	delete document;
	imageStream->Dispose();
}

Encrypt Word Document in C++

#include "pch.h"
using namespace Spire::Doc;

int main() {
	wstring input_path = DATAPATH;
	wstring inputFile = input_path + L"Template.docx";
	wstring output_path = OUTPUTPATH;
	wstring outputFile = output_path + L"Encrypt.docx";

	//Create word document
	Document* document = new Document();

	//Load Word document.
	document->LoadFromFile(inputFile.c_str());

	//encrypt document with password specified by textBox1
	document->Encrypt(L"E-iceblue");

	//Save as docx file.
	document->SaveToFile(outputFile.c_str(), FileFormat::Docx);
	document->Close();
	delete document;
}
