Hi James ,            We tried this pseudo code but still we are not able to load two mmpk data for single screen.Go through this code if i am doing any mistak, Please inform. path1 = "/home/Gis/ChartEngine/Arcgis/Runtime/Data/MMpk/India.mmpk"; path2 = "/home/Gis/ChartEngine/Arcgis/Runtime/Data/MMpk/Pak.mmpk"; void CTacticalViewClass::LoadingOfmmpkfile(const QUrl &file,const QUrl &file2) {     QString dataPath = file.toString();     QString dataPath2 = file2.toString();       m_mobileMapPackage = new MobileMapPackage(dataPath, this);     m_mobileMapPackage1 = new MobileMapPackage(dataPath2, this);       connect(m_mobileMapPackage, &MobileMapPackage::doneLoading, this, [this](Error error)     {         if (error.isEmpty())         {             m_mapView->setMap(m_mobileMapPackage->maps().at(0));             m_mobileMapPackage1->load();         }     });     connect(m_mobileMapPackage1, &MobileMapPackage::doneLoading, this, [this](Error)   {           auto* map2 = m_mobileMapPackage1->maps().at(0);         qDebug()<<"Operational layer count ------>>"<<m_mobileMapPackage1->maps().at(0)->operationalLayers()->size()<<"map2"<<map2->operationalLayers()->size();//here 3 operational layer is coming           QList<Layer*> layersFromMap2; //***** We made changes in for loop because we were getting error in for loop         LayerListModel* layerFromMap2;         for (int i = 0;i<m_mobileMapPackage1->maps().at(0)->operationalLayers()->size();i++)         {             layersFromMap2.append(m_mobileMapPackage1->maps().at(0)->operationalLayers()->at(i));             layerFromMap2 = map2->operationalLayers();             layerFromMap2->setParent(this); // re-parent the layers         }          qDebug()<<"layersFromMap2"<<layersFromMap2.size()<<"layerFromMap2 "<<layerFromMap2->size();         // delete the map               delete map2;  ////********************** After deletion of map2 ,we are getting operational layers as zero         //      // add all the layers to the mapView's map               auto* operationalLayers = m_mapView->map()->operationalLayers();                 for (auto* layer : layersFromMap2)                 operationalLayers->append(layer);               qDebug()<<"total layers "<<operationalLayers->size();     });     m_mobileMapPackage->load(); ...

Hi ,     Thank you for reply , I am not able to re-author the data .It will be very appreciable if you can provide some example code ,for loading more than one mmpk file for single mapview. ... View more

hi,     I understand what you want to tell.But My confusion is related to database file which will contain tables.I have India.shp , India.shx and India.dbf file.To Know column names which file i will use (India.shp, India.shx or India.dbf) or anyother file will be required .If possible can you give some example of your used shape file and database file.It will be more helpfull.

Thanku for reply. I Have taken a look at the labeling sample  -arcgis-runtime-samples-qt/ShowLabelsOnLayers.cpp at master · Esri/arcgis-runtime-samples-qt · GitHub . After code change  i am not able to get state names and  getting some error like this Exception thrown in Feature_source_layer::Feature_source_layer_label_data_source::get_next_feature() - "SQL error or missing database" - "no such column: rte_num1" which file i have to prefer for column name .shp, .shx or .dbf file please check this code void CTacticalViewClass::LoadingOfServiceFeatureFile() {     ShapefileFeatureTable* servicefeatureTable = new ShapefileFeatureTable("/home/GIS/Desktop/ChartEngineMainFolder/ChartEngine/ArcGIS/Runtime/Data/shp/India/india_st.shp", this);     servicefeatureTable->load();     FeatureLayer* featureLayer = new FeatureLayer(servicefeatureTable, this);     connect(featureLayer, &FeatureLayer::doneLoading, [this, featureLayer](Error e)     {         if (!e.isEmpty())             return;         m_mapShapeView->setViewpoint(Viewpoint(featureLayer->fullExtent().center(), 56759600));     });     m_Shapemap->operationalLayers()->append(featureLayer);     // Apply labels to the feature layer     const QString labelJson = createLabelJson();     LabelDefinition* labelDef = LabelDefinition::fromJson(labelJson, this);     featureLayer->labelDefinitions()->append(labelDef);     featureLayer->setLabelsEnabled(true); } QString CTacticalViewClass::createLabelJson() const {     return QString(QStringLiteral("{\"labelExpressionInfo\":{\"expression\":\"'I - ' + $feature.rte_num1\"},\"labelPlacement\":\"esriServerLinePlacementAboveAlong\",\"where\":\"rte_num1 <> ' '\",\"symbol\": {\"angle\":0,\"backgroundColor\":[0,0,0,0],\"borderLineColor\":[0,0,0,0],\"borderLineSize\":0,\"color\":[0,0,255,255],\"font\": {\"decoration\":\"none\",\"size\":15,\"style\":\"normal\",\"weight\":\"normal\"},\"haloColor\":[255,255,0,255],\"haloSize\":1.5,\"horizontalAlignment\":\"center\",\"kerning\":false,\"type\":\"esriTS\",\"verticalAlignment\":\"middle\",\"xoffset\":0,\"yoffset\":0}}")); }   ...

hi,I am new in Arcgis .I want to know how i can show state names on shape file.Currently i am using following code to load shape file from local system. void CTacticalViewClass::LoadingOfShapeFile(const QUrl& file) {     QString dataPath = file.toString();//this contains india.shp     ShapefileFeatureTable* featureTable = new ShapefileFeatureTable(dataPath, this);     featureTable->load();     layer = new FeatureLayer(featureTable, this);     m_Shapemap->operationalLayers()->append(layer);     m_mapShapeView->setMap(m_Shapemap);     m_mapShapeView->show();     m_mapShapeView->raise(); } ...
