Introduction: 
 
This article clearly 
explains about how to automate or force the Send/Receive event in the outlook 
using vb.net. This code can be used as a service and made to automate the 
Send/Receive event in the outlook for a regular interval. 
 
Summary:
          
The following steps will 
help us to create the application.
 
Step 1:
Start Microsoft Visual Studio .NET.
 
Step 2: 
On the File menu, click New, and then click Project.
 
Step 3: 
Click Visual Basic Projects under Project Types, and then click 
Console Application under Templates. By default, Module1.vb is 
created.
 
Step 4: 
Add a reference to the Microsoft Outlook 10.0/11.0 Object Library. 
To do this, follow these steps: 
 
- 
	
		On the Project 
		menu, click Add Reference.
	 - 
	
		On the COM 
		tab, click Microsoft Outlook 
		10.0/11.0 Object Library, and then click Select.
	 - 
	
		Click OK in 
		the Add References dialog box to accept your selections. If you 
		are prompted to generate wrappers for the library that you selected, 
		click Yes.
	 
 
Step 5: 
In the Code window, replace all of the code with the following:
 
        
Automate Send & Receive:
 
Imports 
System.Reflectio
Module 
Module1
   
Sub Main()
       
Try
           
'Microsoft.Office.Interop.Outlook._Application
           
' Create an Outlook application.
           
Dim oApp As 
Outlook._Application = New Outlook.Application
           
' Get the MAPI NameSpace and Logon values.
           
Dim oNS As 
Outlook._NameSpace = CType(oApp.GetNamespace("MAPI"),
             
outlook._NameSpace)
            
oNS.Logon(Missing.Value, Missing.Value, True,
True)
 
           
'Get Explorer for the folder.
           
Dim oExp As 
Outlook._Explorer = oFolder.GetExplorer(False)
 
           
'Get the Menu bar.
           
Dim oCmdBars As 
office._CommandBars = oExp.CommandBars
           
Dim oCmdBar As 
office.CommandBar = oCmdBars("Menu Bar")
            
Console.WriteLine(oCmdBar.Name)
           
Dim oBarCrls As 
office.CommandBarControls = oCmdBar.Controls
            
Console.WriteLine(oBarCrls.Count)
           
Dim oBP As 
office.CommandBarPopup
 
           
'Get the Tools menu.
           
Dim oBPop As 
office.CommandBarPopup = CType(oBarCrls("Tools"), 
            
office.CommandBarPopup)
            
Console.WriteLine(oBPop.Caption)
            oBarCrls = 
oBPop.Controls
           
Dim oBn As 
office.CommandBarControl
 
           
'Get the Send/Receive menu.
           
Dim oSendReceive As 
office.CommandBarPopup =   
           
CType(oBarCrls("Send/Receive"), 
office.CommandBarPopup)
            
Console.WriteLine(oSendReceive.Caption)
 
            'Get 
the Send and Receive All menu.
            oBarCrls = 
oSendReceive.Controls
 
           
'TO DO: If you use the Microsoft Outlook 10.0 Object 
Library,  
           
'uncomment the following line.
 
           
'Dim oSendReceiveAll As Office.CommandBarControl =
           
'CType(oBarCrls("Send and Receive All"), 
Office.CommandBarControl)
 
           
'TO DO: If you use the Microsoft Outlook 11.0 Object 
Library, 
           
' uncomment the following line.
 
           
'Dim oSendReceiveAll As Office.CommandBarControl =
           
' CType(oBarCrls("Send/Receive All"), 
Office.CommandBarControl)
 
            
Console.WriteLine(oSendReceiveAll.Caption)
 
           
'Do the action.
            
oSendReceiveAll.Execute()
 
           
'Log off.
            oNS.Logoff()
 
           
'Clean up.
            oApp =
Nothing
            oNS =
Nothing
            oFolder =
Nothing
            oExp =
Nothing
       
Catch e As 
Exception
            
Console.WriteLine("{0} Exception caught.", e)
       
End Try
   
End Sub
 
Step 6: 
Press F5 to build and run the program.
 
Step 7: 
Verify that the Contact Detail (contact detail in outlook format) is received 
through mail
 
Conclusion:
 
This process even can be achieved by inbuilt schedule 
option of the Microsoft Outlook. If it was done it needs the outlook to be open 
but in our case its not needed and the same is achieved through the vb.net 
coding.
