Managing Document Properties
Possible Usage Scenario
Aspose.Cells allows you to work with Built-In and Custom document properties. Here is the Microsoft Excel interface to open these Document Properties. Just click on the Advanced Properties as shown in this screenshot and view them.
Managing Document Properties
The following sample code loads sample excel file and reads the built-in document properties e.g. Title, Subject and then changes them. Then it also reads the custom document property i.e. MyCustom1 and then adds a new custom document property i.e. MyCustom5 and writes the output excel file. The following screenshot shows the effect of the sample code on the sample excel file.
Sample Code
Aspose::Cells::Startup(); | |
//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C | |
//Source directory path | |
U16String dirPath(u"..\\Data\\LoadingSavingAndConverting\\"); | |
//Output directory path | |
U16String outPath(u"..\\Data\\Output\\"); | |
//Paths of source and output excel files | |
U16String samplePath(dirPath + u"sampleManagingDocumentProperties.xlsx"); | |
U16String outputPath(outPath + u"outputManagingDocumentProperties.xlsx"); | |
//Load the sample excel file | |
Workbook wb(samplePath); | |
//Read built-in title and subject properties | |
U16String strTitle = wb.GetBuiltInDocumentProperties().GetTitle(); | |
U16String strSubject = wb.GetBuiltInDocumentProperties().GetSubject(); | |
U16String title(u"Title: "); | |
std::cout << title.ToUtf8() << strTitle.ToUtf8() << std::endl; | |
U16String subject(u"Subject: "); | |
std::cout << subject.ToUtf8()<<strSubject.ToUtf8() << std::endl; | |
//Modify built-in title and subject properties | |
strTitle = u"Aspose.Cells New Title"; | |
strSubject = u"Aspose.Cells New Subject"; | |
wb.GetBuiltInDocumentProperties().SetTitle(strTitle); | |
wb.GetBuiltInDocumentProperties().SetSubject(strSubject); | |
//Read the custom property | |
U16String strCustomPropName(u"MyCustom1"); | |
U16String strCustomPropValue = wb.GetCustomDocumentProperties().Get(strCustomPropName).ToString(); | |
U16String myCustom1(u"\r\nMyCustom1: "); | |
std::cout << myCustom1.ToUtf8()<<strCustomPropValue.ToUtf8() << std::endl; | |
//Add a new custom property | |
strCustomPropName = u"MyCustom5"; | |
strCustomPropValue = u"This is my custom five."; | |
wb.GetCustomDocumentProperties().Add(strCustomPropName, strCustomPropValue); | |
//Save the output excel file | |
wb.Save(outputPath); | |
Aspose::Cells::Cleanup(); |
