Npace data basic operation
I. Data source
Open work space
SuperWorkspace.Open ();
SuperWorkspace.save ();
SuperWorkspace.saveas ();
Create a data source
SuperWorkspace.createdASource ()
2. Open data source
SuperWorkspace.OpendataSource ()
SuperWorkspace.opendataSourceEx () Space Database type
3. Get data sources
SuperWorkspace.DataSource.Item ()
4. Turn off the data source
SuperWorkspace.DataSource.Remove ()
SuperWorkspace.DataSource.RemoveAll ()
Ii. Data set
1. Create a data set
Sodatasource.createdTASet ();
2. Get the data set
SodataSource.DataSets.Item ();
SuperWorkspace.DataSources.Item (i) .DataSets.Item (i)
SuperMap.Layers.Item (i) .dataset
SuperMap.selection.Item (i) .dataset
3. Delete the data set
Sodatasource.deletedASet ()
Display data set
Solayers.addDataSet () SOLAYERS.REFRESH ()
Iii. Basic operation
SuperMap.Action Seaction constant
SuperMap.action = scazoomin (zoom)
SuperMap.Viewentire ()
Editing operation
SuperMap.action = scaeditcreatepoint
SuperMap.Action = ScaEditcreatePolyline
SuperMap.Action = ScaEditcreatePolygon
Track layer editing
Supermap.action = scatrackpoint
SuperMap.action = scatrackpolyline
Supermap.action = scatrackpolygon
IV. Layer Management
Visual management can be implemented through the SuperleGend control. After updating supermap.refresh ()
You can also be set by Solayer.editable, Solayer.Selectable, Solayer.Snapable, Solayer.Snapable, Solayer.Snapable, Solayer.Visible.
1. Style setting of the point line layer:
SuperMap.Layers (i) .style
SuperMap.ShowStypicker (Sostyle, Dimension)
2. Text-layer layer style:
SuperMap.ShowTextStypicker ()
3. Save the map:
Supermap.savemap ()
SuperMap.OpenMap ()
4. Display: Solayer.visibleScalemax, Solayer.visibleScalemin
Filter is filtered by the object size, pixel display, Filterk can filter display.
V. Recording set socordset
Get record set
SodatasetVector.Query (SQL, TRUE)
SodatasetVector.Queryex (SQL, TRUE)
SodatasetVector.QueryByDistance (SQL, TRUE)
SOSELECTION.TORECORDSET ()
2. Add record:
SorecordSet.AddNew ()
Add SorecordSet.AddNew (Nothing)
3. Add: SoGeometry
Recordset.getGeomotry ()
Recordset.setGeometry ()
Get from the event: Geometry_selected ()
Supermap.aftergeometryAdded ()
4. Select Sets and Record Sets
Selection.torecordset ()
Selection.FromRecordset ()
5. Do not check the selected
SOSELECTION.Remove
SOSELECTION.REMOVEAll
6. Process of querying properties by map
Select Object () - "Get Record Set -" Value Display
Selection.torecordset () - "SorecordSet.GetfieldValue
7. Query the process of the map by attribute
Settings for Query Conditions - "Get Query Records -" Add to Select Set
Layer.DataSet- "SodatasetVector-" SodatasetVector.Query (SQL, TRUE) - "Selection.FromRecordset ()
Vi. Tracking Layer
The tracking layer is the top layer of all layers, and there is a TRACKINGLAYER.
The tracking layer is temporarily placed in memory, turning off the Layer, then trackinglayer disappears
Tracking layer speed is relatively fast, you can update the spatial object
1. Add an object to the tracking layer
Sotrackinglayer.addevent (ObjGeometry, Objstyle, String)
Set Geometry, style, and labels separately
2. Get the objects above the tracking layer
SotrackingLayer. Event
3. Remove the objects above the tracking layer
SotrackingLayer.clearevents ()
4. Move the object on the tracking layer
Sogeoevent.move ()
SoGeoevent.moveto ()
5. Different geometries and text objects
The style of the geometric object corresponds to Sostyle
The style corresponding to the text object is SotextStyle
VII. Layout Object SuperLayout
1. Select the object SuperLayout.Seelection in the layout window
2. Elements in the layout window SuperLayout.efficients
3. Mouse event in the layout window SuperLayout.lytAction
4. Map objects in Superlayout, solYtmap
5. SolytMap.maphold lock map can be enlarged by solitmap.mapaction
Viii. The association of map controls
-Superlegend1.connect supermap1.handle
-Supermap1.connect superWorkspace1.Handle
-SuperLayout1.connect superWorkspace1.Handle
-Superwkspmanager1.connect superWorkspace1.Handle
-Supergridview1.connect ObjRecordset
IX. Map Control Release Order
-SuperLegend1.disconnect
-Supermap1.close
-Supermap1.disconnect
-SuperLayout1.disconnect-superwkspmanager1.disconnect
-SuperWorkspace1.close
