Re[mapguide-users] turn all Layers from MapGuide repository

Hi,

The following code should do what you're looking for.

	Public Shared Function GetAllResources(ByRef resSvc As
MgResourceService, ByVal resId As MgResourceIdentifier, ByVal nDepth As
Integer, ByVal szType As String) As XmlDocument
		Dim retDoc As XmlDocument
		retDoc = ConvertMgReaderXml(resSvc.EnumerateResources(resId,
nDepth, szType))
		Return XmlDocument
	End Function

Set the , resID to "Library://",  depth to -1 I believe for full recursion.
For Type use LayerDefinition

And ConvertMgReaderXML is:
	Public Shared Function ConvertMgReaderXml(ByVal byteReader As
MgByteReader) As XmlDocument
		Dim szXML As String
		Try
			szXML = byteReader.ToString
		Catch ex As Exception
			Throw ex
		End Try
		Dim nByteCount As Integer
		Dim arrByte(szXML.Length) As Byte
		Try
			nByteCount = Encoding.UTF8.GetBytes(szXML, 0,
szXML.Length, arrByte, 0)
		Catch ex As Exception
			Throw ex
		End Try

		Dim memStream As New MemoryStream(arrByte)
		Dim retDoc As New XmlDocument
		retDoc.PreserveWhitespace = True
		Try
			retDoc.Load(memStream)
		Catch ex As Exception
			memStream.Close()
			memStream.Dispose()
			Throw ex
		End Try
		memStream.Close()
		memStream.Dispose()
		Return retDoc
	End Function

Hope that helps.

Subject: Re[mapguide-users] turn all Layers from MapGuide repository


Hello All,

Currently working with the API for MapGuide OpenSource 2.0 and have a
requirement for returning all layers from the MapGuide repository.

I am able to return all layer names for a particular map using the below C#
code

            map.Open(resService, mapName);

            MgLayerCollection layers = map.GetLayers();

            ArrayList layerNames = new ArrayList();

            for (int i = 0; i < layers.GetCount(); i++)
            {
                MgLayer layer = (MgLayer)layers.GetItem(i);

                string layerType = layer.GetFeatureGeometryName();
              
                    layerNames.Add(layer.GetName());
            }

How would I go about returning all Layers in the MapGuide repository as a
large number of layers won't be associated with a map?

Many Thanks,

Adnan
