Convertir datos del proyecto a HTML en C ++

Microsoft Project (MSP) permite a los desarrolladores guardar los datos del proyecto (MPP/XML) a HTML. Aspose.Tasks for C ++ API también le permite guardar los datos del proyecto en los mismos formatos similares a MSP. Esto se logra utilizando el método de guardado estándar expuesto por la clase Proyecto.

Guardar datos del proyecto como html

Aspose.Tasks para C ++ puede exportar los datos del proyecto al formato HTML. Permite guardar todos los datos en HTML o exportar solo las páginas requeridas a HTML utilizando las SaveOptions como se muestra en las siguientes muestras de código.

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.
