How do I change color of annotation through code?

AshalaPalaniuk — Wed, 26 May 2010 20:33:55 GMT

Hello Fellow-Forum-ers!

I have an application that loads a whole bunch of layers, some of which are SDE annotation layers. I cannot figure out how to change the symbology of the annotation, namely color (but also size). For simplicity sake and for testing I am working with only one layer in a new, separate document and have included my code below for bringing in the annotation layer. While this differs from my actual application this serves its purpose for trouble-shooting.

So my question is - how do I change the color that this annotation layer loads in?

Any help pointing me in the right direction would be appreicated as I am definitely stumped. Thanks so much!

Private Function MxDocument_OPENDOCUMENT() As Boolean

Dim pPropset As IPropertySet
Set pPropset = New PropertySet
With pPropset
.SetProperty "Server", "*****"
.SetProperty "Instance", "*****"
.SetProperty "user", "*****"
.SetProperty "password", "*****"
.SetProperty "version", "*****"
End With

Dim pworkspacename As IWorkspaceName
Set pworkspacename = New WorkspaceName
pworkspacename.WorkspaceFactoryProgID = "esricore.SdeWorkspaceFactory"
pworkspacename.ConnectionProperties = pPropset

Dim pdatasetName As IDatasetName
Set pdatasetName = New FeatureClassName

pdatasetName.Name = "chwksde.dbo.SS_SansymAnno"
Set pdatasetName.WorkspaceName = pworkspacename

Dim pname As IName
Set pname = pdatasetName

Dim ptable As ITable
Set ptable = pname.Open

Dim pfeatclass As IDataset
Set pfeatclass = ptable

Dim pfeatlay As IFeatureLayer
Dim pFDOGraphicsLayerFactory As IFDOGraphicsLayerFactory
Set pFDOGraphicsLayerFactory = New FDOGraphicsLayerFactory
Set pfeatlay = pFDOGraphicsLayerFactory.OpenGraphicsLayer(pfeatclass.Workspace, Nothing, "chwksde.dbo.SS_SansymAnno")

pfeatlay.Name = pfeatclass.Name

Dim pmap As IMap
Dim pmxdoc As IMxDocument

Set pmxdoc = ThisDocument
Set pmap = pmxdoc.ActiveView

pmap.AddLayer pfeatlay

Dim pav As IActiveView
Set pav = pmap

pav.Refresh

End Function

It figures that after toiling over it for ages I come to my conclusion shortly after I post it! Here is the solution for anyone that's wondering. I pieced part of this from a previous post solution that I found by Babak - many thanks to you!

Private Function mxDocument_opendocument() As Boolean

Dim pPropset As IPropertySet
Set pPropset = New PropertySet
With pPropset
.SetProperty "Server", "*****"
.SetProperty "Instance", "*****"
.SetProperty "user", "*****"
.SetProperty "password", "*****"
.SetProperty "version", "*****"
End With

Dim pworkSpacename As IWorkspaceName
Set pworkSpacename = New WorkspaceName
pworkSpacename.WorkspaceFactoryProgID = "esricore.SdeWorkspaceFactory"
pworkSpacename.ConnectionProperties = pPropset

Dim pdatasetName As IDatasetName
Set pdatasetName = New FeatureClassName

pdatasetName.Name = "chwksde.dbo.SS_SansymAnno"
Set pdatasetName.WorkspaceName = pworkSpacename

Dim pname As IName
Set pname = pdatasetName

Dim ptable As ITable
Set ptable = pname.Open

Dim pfeatclass As IDataset
Set pfeatclass = ptable

Dim pAnnotationLayer As IAnnotationLayer
Dim pFDOGraphicsLayerFactory As IFDOGraphicsLayerFactory
Set pFDOGraphicsLayerFactory = New FDOGraphicsLayerFactory
Dim player As ILayer
Set pAnnotationLayer = player
Set pAnnotationLayer = pFDOGraphicsLayerFactory.OpenGraphicsLayer(pfeatclass.Workspace, Nothing, "chwksde.dbo.SS_SansymAnno")

Dim pRGBColorAnno As IRgbColor
Set pRGBColorAnno = New RgbColor

With pRGBColorAnno
    .Red = 255
    .Green = 0
    .Blue = 0
End With

Dim pFDOGraphicsLayer As IFDOGraphicsLayer
Dim pFDOGraphicsRead As IFDOGraphicsLayerRead
Dim symbolSubstitution As ISymbolSubstitution

Set pFDOGraphicsLayer = pAnnotationLayer
Set pFDOGraphicsRead = pFDOGraphicsLayer
Set symbolSubstitution = pFDOGraphicsRead

symbolSubstitution.SubstituteType = esriSymbolSubstituteColor
Set symbolSubstitution.MassColor = pRGBColorAnno
Set symbolSubstitution.InlineColor = pRGBColorAnno

Dim pmap As IMap
Dim pmxdoc As IMxDocument

Set pmxdoc = ThisDocument
Set pmap = pmxdoc.ActiveView

pmap.AddLayer pAnnotationLayer

Dim pav As IActiveView
Set pav = pmap

pav.Refresh

End Function
