ZEESHAN,  
&nbsp;  
You’d&nbsp;better&nbsp;add&nbsp;a&nbsp;key&nbsp;to&nbsp;each&nbsp;layer/Overlay,&nbsp;so&nbsp;you&nbsp;can&nbsp;delete&nbsp;them&nbsp;easily.&nbsp;Just&nbsp;like&nbsp;the&nbsp;following&nbsp;code,&nbsp;"Line\_imfl"&nbsp;isthe&nbsp;key&nbsp;of&nbsp;inMemoryFeatureLayer,  
"overlay"&nbsp;is&nbsp;the&nbsp;key&nbsp;of&nbsp;lineOverlay.  
&nbsp;  
Dim&nbsp;lineOverlay&nbsp;As&nbsp;New&nbsp;LayerOverlay()  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;lineOverlay.Layers.Add("Line\_imfl",&nbsp;inMemoryFeatureLayer)  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WinformsMap1.Overlays.Add("overlay",&nbsp;lineOverlay)  
&nbsp;  
Here&nbsp;is&nbsp;the&nbsp;code&nbsp;you&nbsp;want.  
&nbsp;  
lineOverlay.Layers.Remove("Line\_imfl")&nbsp;&nbsp;&nbsp;&nbsp;'remove&nbsp;inMemoryFeatureLayer&nbsp;from&nbsp;lineOverlay  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WinformsMap1.Overlays.Remove("overlay")&nbsp;&nbsp;&nbsp;'remove&nbsp;lineOverlay&nbsp;from&nbsp;WinformsMap  
&nbsp;  
Thanks,  
James
