Convert Project Data to HTML in C++

Microsoft Project (MSP) allows developers to save project data (MPP/XML) to HTML. Aspose.Tasks for C++ API also allows you to save project data to the same formats similar to MSP. This is achieved using the standard Save method exposed by the Project class.

Saving Project Data as HTML

Aspose.Tasks for C++ can export project data to HTML format. It allows to save all the data to HTML or export only required pages to HTML by using the SaveOptions as shown in the following code samples.

System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"CreateProject2.mpp");
System::SharedPtr<HtmlSaveOptions> option = System::MakeObject<HtmlSaveOptions>();
project->Save(dataDir + u"SaveProjectDataAsHTML_out.html", option);
    
// OR
    
// Adding only one page (page number 2)
option = System::MakeObject<HtmlSaveOptions>();
option->get_Pages()->Add(2);
project->Save(dataDir + u"SaveProjectDataAsHTML2_out.html", option);

Controlling Document Header Name during Export to HTML

System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"CreateProject2.mpp");
System::SharedPtr<HtmlSaveOptions> htmlSaveOptions = System::MakeObject<HtmlSaveOptions>();
    
// Determines whether to include project name in HTML title (true by default)
htmlSaveOptions->set_IncludeProjectNameInTitle(false);
    
// Determines whether to include project name in HTML page header  (true by default)
htmlSaveOptions->set_IncludeProjectNameInPageHeader(false);
    
htmlSaveOptions->set_Pages(System::MakeObject<System::Collections::Generic::List<int32_t>>());
htmlSaveOptions->get_Pages()->Add(1);
project->Save(dataDir + u"ControlHeaderNameDuringHTMLExport_out.html", htmlSaveOptions);

Saving Fonts, Images and CSS Styles Separately

Aspose.Tasks for C++ API gives you enough power to save fonts, images, and CSS styles information separately to files while saving Project Data to HTML. This is achieved using the HtmlSaveOptions class by providing information about CSS, Font and Image destinations.
