workspace for selected feature

shivagugila — Fri, 13 Aug 2010 07:48:48 GMT

Hi All,

Is there any line of code in VBA to "set workspace of selected feature". i am working on code that will enable the snap environment of layer of selected feature from map.
Any sort of help is appreciated. Thanks in advance.

I'm guessing you mean you want to know how to get a reference to the workspace that a feature comes from? If so,

Dim objectClass As IObjectClass
Set objectClass = feature.Class
Dim dataset As IDataset
Set dataset = objectClass
Dim workspace As IWorkspace
Set workspace = dataset.Workspace

Hi Neil,

The code for 'Addsnapagentfor selected feature' creates a duplicate layer to set a new snap agent, which i am unable to resolve. Can you please look into the code lines and give your comment. Screenshot for snapwindow is also attached.

'setting snapagent

    Dim pFeatureClass As IFeatureClass
    Set pFeatureClass = pfworkspace.OpenFeatureClass(lay_name)

    Dim pSnapEnvironment As ISnapEnvironment
    Dim pFeatureSnapagent As IFeatureSnapAgent
    Set pSnapEnvironment = pEditor
    Set pFeatureSnapagent = New FeatureSnap
    Set pFeatureSnapagent.FeatureClass = pFeatureClass
    pFeatureSnapagent.HitType = esriGeometryPartVertex


   'pSnapEnvironment.ClearSnapAgents
    pSnapEnvironment.AddSnapAgent pFeatureSnapagent
    pSnapEnvironment.SnapToleranceUnits = esriSnapTolerancePixels
    pSnapEnvironment.SnapTolerance = 5

Thanks in advance,
Regards,
Shiva

Your code is creating a new snap agent and adding it to the snap environment. If there is already a snap agent for the layer then you need to get that snap agent and modify it instead of adding a new snap agent. You can do this by looping through the snap agents and checking the feature class and/or name until you find the one you're looking for.
