I want to change the symbol of features and legend programmatically. When I use this code

Dim pSymbolSelector As ISymbolSelector
Set pSymbolSelector = New SymbolSelector
Dim pMarker As ISimpleMarkerSymbol
Set pMarker = New SimpleMarkerSymbol
If Not pSymbolSelector.AddSymbol(pMarker) Then
       MsgBox "Could not add symbol"
ElseIf pSymbolSelector.SelectSymbol(0) Then
       Dim pSymbol As ISymbol
       Set pSymbol = pSymbolSelector.GetSymbolAt(0)
End If

then Symbol Selector is open, but when I select a symbol it is not being applied at the current layer in Table of Contents. Please give any ideas.

According to the ESRI documentation: "The SymbolSelector class is used for presenting the user with a choice of symbols: marker, line, fill, or text. The symbols in the selector are taken from the currently referenced style files."

If you want to handle this task programmatically, without user input, you can use IFeatureRenderer.

You're using 'ISimpleMarkerSymbol', which will give you a point marker. The code you posted is for point symbols, not line/polygon. IFeatureRenderer is still your best bet. –  Nick Ochoski Aug 31 '12 at 16:16
