how to use the Enterprise Library 5 connecting to a MS Access database using VB.NET 2010 on a windows forms application. Looking for quick code samples on how to add, select, update, delete records from an Access database.I'm trying to adopt Enterprise Library in my applications but I'm not finding much information on it.

View 2 RepliesIn my shop we currently develop what I would consider small to medium sized projects.We have been investigating the Enterprise Library and how it may be able to help us in development.I have particularly been looking at the Logging block and comparing it with Log4Net.It seems to me that the Enterprise Library blocks would be an extremely over-engineered solution for something like simple application logging.That being said. Are you using the Enterprise Library and on what size projects? What are your thoughts on the Enterprise Library as a whole?
View 10 RepliesI just got finished watching a short video on logging using some of the built in concepts in Visual Studio 2005. This seems to do a good job. My question is why do people look for other solutions to logging such as Enterprise Library or Log4Net when there is a simple solution out of the box?
The video I watched primarily used the following for logging.
Code: My.Application.Log.WriteEntry(sb.ToString, type)
I'm trying to use the Enterprise Library RangeValidator attribute to validate that a decimal value is greater than zero:
<RangeValidator(GetType(Decimal), "0.00", RangeBoundaryType.Exclusive, "1", RangeBoundaryType.Ignore, "MyMessage", "", Nothing, False, "", "")> _
Public Property Holding() As Decimal

As far as I can see I am using the overload correctly. It works fine if I remove the messageTemplate related parameters but I want to be able to specify a custom message.

View 6 RepliesFor the life of me I can not find the Enterprise Library Strong Naming Guidance Package download for Enterprise Library 4.1
I need this to sign the assemblies to add them to the GAC.
Does anybody know where I can find it?
we are using the Enterprise Library data access application block in our data layer for an application. We must be doing something wrong though because we cannot seem to get encryption and the ability to reconfigure connection strings working well. For example, when the application starts, it checks if the connection strings are "Protected", and if they are not, we encrypt them using the following function:
[Code]...
Then comes another issue. If a user installs an update for the application, the first time it runs, nothing can connect if the config file was previously encrypted. A restart of the application (second time running) will fix the issue. with all of the battles we are fighting here, I wanted to ask if we are doing this right? How should we be encrypting and allowing updates. If you need to see the exceptions thrown, I can provide those upon request (will need to change some code to get them again, but it is doable).
Our app allows admins to connect to a different database, which means we need to temporarily decrypt the app.config's connection strings, re-write them, then re-encrypt it. Here's my current 'simplified' code showing how we do all 3 tasks:
Dim config As Configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
Dim section As ConfigurationSection = config.GetSection("connectionStrings")

View 5 RepliesI have vb .net windows form application that I want to connect to Microsoft access database using "Microsoft DAO 3.6 object library". My problem is that when I go to Project tab -> Add reference -> COM tab, there should have been "Microsoft DAO 3.6 Object Library" on the list, but for some reason It's not on the list. Then I googled, and found out that the location of "DAO360.DLL" is "Program FilesCommon FilesMicrosoft SharedDAO". After clicking on Browse tab, I browsed to that location, and I guess I added reference on another way.This is the code that I used before for connecting to Access, but for some reason It doesn't work this way on this PC.

I have the following projects:
TradingProject (my code) Has reference to TradingLibrary, and to ApiLibrary?
TradingLibrary (my code) Has reference to ApiLibrary
ApiLibrary (3rd party code)
I'm making several projects (like TradingProject) that communicate with a software through use of an existing ApiLibrary. But I want to push generic methods into a library I write: TradingLibrary.
Still, I would like to use some parts of the ApiLibrary directly from TradingProject. However, I then would need to pass an object (of an ApiLibrary class) into a method in TradingLibrary. Where the object should be recognized. However I assume this will be a problem, as TradingLibrary use it's own reference to ApiLibrary, so it will not be recognized as the same classes? Is there some way I can "forward" the ApiLibrary reference from TradingLibrary to MyProject, such that they will use the same reference? Or do I need to duplicate the classes and inherit from ApiLibrary for each class? Like:
NameSpace TradingLibrary
Public Class SomeClass
Inherits ApiLibrary.SomeClass
End Class
I guess that would work, if I do it for all classes I need, but is there perhaps some simpler way I'm not aware of?
I'm building a generic Class Library that I will use it in all my projects.

I have been using VB6 to manipulate MS Access 2000 databases via the DAO 3.6 library on Win XP. I have recently acquired Visual Basic Express 2010 and I have not been able to port my VB6 code. I can not find any sample code to use MS Access 2000 from VBE 2010. Is it possible to access MS Access 2000 from VBE 2010?
Here is my VB6 code:

I'm using PInvoke to access some routines from a third party library, however i'm getting SEHExceptions when trying to use callbacks defined for one particular method.

View 15 RepliesI've created a class library and built a dll (release build). I've then referenced the DLL in another project (I've tried several). I can see the namespace and classes in Object Browser and I can declare instances of the classes but I cannot use or see any of the methods or properties! there is no IntelliSense whatsoever and calling the methods manualy results in a 'Declaration expected' error.
Within the class library solution I have a unit test project referencing the class library project which works all works fine (and all the tests pass).
Can anyone provide any pointers to what might be going wrong here? I've built plenty of dlls in the past and have had no trouble referencing them at all.[code]...

I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time.
