[mapguide-users] Create programmatically a map

Wed Feb 18 05:41:41 EST 2009

Hi Ivan,
below, you can see my code to create the new map: 

Dim resID As New
MgResourceIdentifier(Library://.../maps/MyMap.MapDefinition) 
Dim enc As New System.Text.UTF8Encoding(False) 
Dim newMapDef As New MgByteSource(enc.GetBytes(XMLMapTemplate.OuterXml),
enc.GetByteCount(XMLMapTemplate.OuterXml)) 
newMapDef.SetMimeType(MgMimeType.Xml) 
Dim resourceSrvc As MgResourceService =
siteConn.CreateService(MgServiceType.ResourceService) 
resourceSrvc.SetResource(resID, newMapDef.GetReader(), Nothing) 
Dim map As New MgMap() 
map.Create(resourceSrvc, resID, MapName) 

... 

Then, this is my code to create the map layout: 
Dim resID As New MgResourceIdentifier(Library://.../Layouts/MyMap.WebLayout) 
Dim enc As New System.Text.UTF8Encoding(False) 
Dim newLayoutDef As New
MgByteSource(enc.GetBytes(XMLLayoutTemplate.OuterXml),
enc.GetByteCount(XMLLayoutTemplate.OuterXml)) 
newLayoutDef.SetMimeType(MgMimeType.Xml) 
resourceSrvc As MgResourceService =
siteConn.CreateService(MgServiceType.ResourceService) 
resourceSrvc.SetResource(resID, newLayoutDef.GetReader(), Nothing) 
map.Save(resourceSrvc) 

Perhaps between map and layout creation I should refresh the mapframe as
suggested from you?

Thanks in advance for your help.
Fabio
