Add Speaker Notes in PowerPoint in C++

There are a number of benefits to using speaker notes in a PowerPoint presentation, such as it can help you stay on point and also appear more confident during a presentation. The following are the steps to add speaker notes to a specified slide.

• Create a Presentation instance and load a PowerPoint document using Presentation->LoadFromFile() method.
• Get a specified slide using Presentation->GetSlides()->GetItem(slideIndex) method.
• Add a notes slide to the slide using ISlide->AddNotesSlide() method.
• Create a TextParagraph instance.
• Set text for the paragraph using TextParagraph->SetText() method, and then append the paragraph to the notes slide using NotesSlide->GetNotesTextFrame()->GetParagraphs()->Append() method.
• Save the result document using Presentation->SaveToFile() method.

PDF/A and PDF/X are two subsets of PDF file formats that were created to standardize the use of PDF in different areas. The former, PDF/A format, is primarily used for the long-term preservation or archiving of electronic documents, while the latter, PDF/X format, is specifically designed for the reliable and accurate pre-print exchange of graphic data. This article will demonstrate how to programmatically convert PDF to PDF/A or PDF/X format using Spire.PDF for C++.

• Get a specific worksheet using Workbook->GetWorksheets()->Get(int index) method.
• Hide specific rows in the worksheet using XlsWorksheet->HideRow(int rowIndex) method.
• Hide Specific columns in the worksheet using XlsWorksheet->HideColumn(int columnIndex) method.
• Save the result file using Workbook->SaveToFile() method.

#include "Spire.Xls.o.h";

using namespace Spire::Xls;

int main()
{
	//Initialize an instance of the workbook class
	intrusive_ptr<Workbook> workbook = new Workbook();
	//Load an Excel file
	workbook->LoadFromFile(L"Input.xlsx");

	//Get the first worksheet
	intrusive_ptr<Worksheet> sheet = dynamic_pointer_cast<Worksheet>(workbook->GetWorksheets()->Get(0));

	//Hide the 3rd and the 7th rows
	sheet->HideRow(3);
	sheet->HideRow(7);

	//Hide the 3rd and the 6th columns
	sheet->HideColumn(3);
	sheet->HideColumn(6);

	//Save the result file
	workbook->SaveToFile(L"HideRowsAndColumns.xlsx", ExcelVersion::Version2013);
	workbook->Dispose();
}

Show Specific Hidden Rows and Columns in Excel in C++

To show specific hidden rows and columns in an Excel worksheet, you can use the XlsWorksheet->ShowRow(int rowIndex) and XlsWorksheet->ShowColumn(int columnIndex) methods. The detailed steps are as follows:

• Initialize an instance of the Workbook class.
• Load an Excel file using Workbook->LoadFromFile() method.
• Get a specific worksheet using Workbook->GetWorksheets()->Get(int index) method.
• Show specific hidden rows in the worksheet using XlsWorksheet->ShowRow(int rowIndex) method.

• Save the result file using Workbook->SaveToFile() method.

#include "Spire.Xls.o.h";

using namespace Spire::Xls;

int main()
{
	//Initialize an instance of the workbook class
	intrusive_ptr<Workbook> workbook = new Workbook();
	//Load an Excel file
	workbook->LoadFromFile(L"HideRowsAndColumns.xlsx");

	//Get the first worksheet
	intrusive_ptr<Worksheet> sheet = dynamic_pointer_cast<Worksheet>(workbook->GetWorksheets()->Get(0));

	//Show the 3rd and the 7th rows
	sheet->ShowRow(3);
	sheet->ShowRow(7);

	workbook->Dispose();
}

Show All Hidden Rows and Columns in Excel in C++

To show all the hidden rows and columns in an Excel worksheet, you need to iterate through all the rows and columns in the worksheet, then find the hidden rows and columns and call the XlsWorksheet->ShowRow(int rowIndex) and XlsWorksheet->ShowColumn(int columnIndex) methods to redisplay them. The detailed steps are as follows:

• Initialize an instance of the Workbook class.
• Load an Excel file using Workbook->LoadFromFile() method.
• Get a specific worksheet using Workbook->GetWorksheets()->Get(int index) method.
• Iterate through all the rows in the worksheet, then find the hidden rows using XlsWorksheet->GetRowIsHide(int rowIndex) method.
• Show the hidden rows using XlsWorksheet->ShowRow(int rowIndex) method.
• Iterate through all the columns in the worksheet, then find the hidden columns using XlsWorksheet->GetColumnIsHide(int columnIndex) method.
• Show the hidden columns using XlsWorksheet->ShowColumn(int columnIndex) method.
• Save the result file using Workbook->SaveToFile() method.

#include "Spire.Xls.o.h";

using namespace Spire::Xls;

int main() 
{
	//Initialize an instance of the workbook class
	intrusive_ptr<Workbook> workbook = new Workbook();
	//Load an Excel file
	workbook->LoadFromFile(L"HideMultipleRowsAndColumns.xlsx");

	//Get the first worksheet
	intrusive_ptr<Worksheet> sheet = dynamic_pointer_cast<Worksheet>(workbook->GetWorksheets()->Get(0));

	//Iterate through all the rows in the worksheet
	for (int i = 1; i <= sheet->GetLastRow(); i++)
	{
		//Check if the current row is hidden
		if (sheet->GetRowIsHide(i))
		{
			sheet->ShowRow(i);
		}
	}

	//Iterate through all the columns in the worksheet
	for (int j = 1; j <= sheet->GetLastColumn(); j++)
	{
		//Check if the current column is hidden
		if (sheet->GetColumnIsHide(j))
		{
			//Show the hidden column
			sheet->ShowColumn(j);
		}
	}

	//Save the result file
	workbook->SaveToFile(L"ShowAllHiddenRowsAndColumns.xlsx", ExcelVersion::Version2013);
