With the following, there is no need to deploy any QDV component in your application package. This way updating of QDV7 requires no further action in the calling application.

Find a complete VB .NET example of this in C:\<QDV Installation folder>\SDK\Sample VB.NET

Procedure:

1.Under Visual Studio, from the sample project, reference QDV assemblies in their installation folder

C:\Program Files\QDV 7\Qdv.CommonApi.dll

* Set 'Copy Local' to False so that they are not copied to your output folder.

The project should run as soon as it is compiled in ANY CPU mode.

 

2.Open C:\<QDV7 Installation folder>\SDK\Sample VB .NET\StartingModule.vb

3.Tell your application where QDV7 is installed:

'---FOLLOWING LINE IS USED TO REFER TO QDV ASSEMBLIES IN ANOTHER FOLDER---
'Private PathWhereQDVIsInstalled As String = QuickDevis.Common.CommonUtility.ApplicationStartupPath & "\"
'When QDV is not in the folder of the current application, you can set this path to its installation folder like this:
Private PathWhereQDVIsInstalled As String = "C:\Program Files\QDV 7"

 

4.Tell your application to load all missing assemblies from that folder:

'---FOLLOWING LINE IS USED TO REFER TO QDV ASSEMBLIES IN ANOTHER FOLDER---

'Following line is used to trigger an event when an assembly is missing. This let's you refer to InterfaceQDV.dll in a folder different than the one of your application

AddHandler AppDomain.CurrentDomain.AssemblyResolve, AddressOf MyResolveEventHandler

 

5.As soon as the Interface is initialized, provide the folder where QDV7 is installed using following function:

'Must take a reference to the component QDV_Interface

MyQDVInterface = New InterfaceQDV.InterfaceQDV.QDVInterface

 

'This is to tell the application that QDV is installed in another folder

MyQDVInterface.SetStartupPathWhereQDVIsNotInApplicationFolder(_PathWhereQDVIsInstalled)
