I'm relatively new to VB.NET programming.I am a C,C++ Programmer.but I know a little bit of VB.NET programming as I knew VB6 a little bit.
I want to use Google Earth COM API.Please give me some thought about Interfaces and Classes and how to use it for API.
My Code is :
[highlight]Public Class Form1
Private GE As EARTHLib.ApplicationGE
Public SC As EARTHLib.ISearchControllerGE
Private PID As Integer
Private Sub func_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles func.Click
Dim src, dest As String
Dim prg As Boolean
Dim feature_clct As EARTHLib.FeatureCollectionGE
GE = New EARTHLib.ApplicationGE
SC = New EARTHLib.SearchControllerGE()
src = txtsrc.Text
dest = txtdest.Text
While StrComp(src, "") <> 0 And StrComp(dest, "") <> 0
SC.Search(src)
Do
prg = SC.IsSearchInProgress()
Loop While prg = True
feature_clct = SC.GetResults()
End While
End Sub
End Class[/highlight]
This is throwing an error :
[quote]Unable to cast COM object of type 'EARTHLib.SearchControllerGEClass' to interface type 'EARTHLib.ISearchControllerGE'.
This operation failed because the QueryInterface call on the COM component for the interface with IID
'{524E5B0F-D593-45A6-9F87-1BAE7D338373}' failed due to the following error: Class not registered
(Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).[/quote]
This is in the line no:
SC.Search(src)
So,plz give me necessarry suggestions.:confused:
