Hi, just a few hints, if you indend to use ArcObjects and C#, and have not found out already:

There are many detalis to consider, and a lot of documentation to read. Online help is useful.

This is approximately how I do it:

"Acivate split processing mode in your code via custom tool event"

"Click on map"

...

IPoint p = mxDoc.CurrentLocation;

IEnvelope e = p.Envelope;

e.Expand( searchRadius);

map.SelectByShape(e,env,justOne);

IFeatureSelection fs = (IFeatureSelection)lineFeaturelayer;

IEnumIDs en = fs.SelectionSet.IDs;
en.Reset();
for(int i=0; i<fs.SelectionSet.Count; i++)
{
	Int32 fid = en.Next();
}	...

IFeature f = lineFeaturelayer.FeatureClass.GetFeature(fid);

IPolyline plin = (IPolyline)f.Shape

plin.SplitAtPoint(p, projecPointOnLine, createPart, out splitDone, out newPartIndex, out newSegmentIndex);

feature1.shape = ..

feature1.Store();

feature2.shape = ..

feature2.Store();

...
