I want to create an enterprise wide dataset so that my function will call this same dataset from any of the webpage. I've created shared code in the App_Code folder. In it, there's are dataset properties. Will the pages extract info from these dataset properties each time I call the shared program or will create new property for each page.I'm trying to emulate an Enterprise Java Bean type of coding.
View 2 RepliesI created a SQL database using the migration tool.I am converting my access forms to VB.net (VS2008).I am wondering if I create a single dataset in studio to the database or do I create a dataset for each form (query)? I am trying to determine what the best solution is. Many of my forms have drop downs that are populated using queries from tables.
View 3 RepliesI seem to be drawing a blank. I'd like to create a "shared" variable that is shared with all instances of a class but not classes that inherit from it. For example.Class A: Shared list As New List(Of String): list.Add("A")
Class B Inherits A: list.Add("B")Class C Inherits B: list.Add("C")The end result I'd like is that any instance of A has just A in the list. Any instance of B has A and B in the list. Any instance of C has A, B, and C in the list. I can accomplish it by creating Instance variables, but I have to construct the list for each instance of a class. I'd like to construct it once for a specific point in the Hierarchy and then share it accross other instances of that class.
I have an untyped DataSet: "ResultsData",which contains several tables: eg "EntryList_table".The Parent Form reads lines from a text file, parses the line, and distributes the necessary data to the corresponding data table.I then have several child forms which contain DataGridViews, each displaying the data in a unique format. All of these tables are Read only, and the DataGrid views only need to display the data attached. However, when I open the child forms, the data does not seem to update with each line read from the text file? As they are bound to the DataTables in 'ResultsData', the column headings appear correct, but will not populate the new data.I would like to have a 'Shared' DataSet that can be accessed by each child form (when activated), and will allow continuous modifications as the input lines are read.
View 6 RepliesVisual Studio 2008 Express Edition.I have a have a DataSet, created from (part of a) Access database. I have tow tables in it (say A and B). When I change something in table A, I need to get data from table B to complete table A.My approach was to use the RowChanged event inside a (Partial) Class of table A. For that to work however table B needs to be shared. (I don't like to refer to an instance.) I got it to work by changing the DataSets designer code, but don't want to do it all over again when the code is regenerated for some reason. So: would there be any way to have these tables shared by default?

View 4 RepliesI've created a Class Library using vb.net, the thing is that several applications should use this file.
I'm using Inno setup, and I'm declaring the dll file to be shared.
in the client app i've added refrence to the dll and set "Copy Local" to false.
Now if i put the exe file (the client app) in the same folder with the dll everything works correctly, but once I move the exe or use another application that should use the so called shared dll the assembly cannot be loaded because the system cannot find him ("IOFileNotFoundException")
I'm doing some LINQ which requires a custom comparer, so I created a new class implementing IEqualityComparer. However, when I use it, I have to create an instance of it each time.
Dim oldListOnly = oldList.Except(newList, New MyEqualityComparer)
Dim newListOnly = newList.Except(oldList, New MyEqualityComparer)
I may be misunderstanding how .NET works, but it seems wasteful to create a new comparer each time. I really just want one instance (the equivalent of static in C++/C#).So I tried creating a "static" class, which in vb.net is a module. But got an 'Implements' not valid in Modules error.I then tried making the Equals and GetHashCode function shared methods on my class, but got this error: Methods that implement interface members cannot be declared 'Shared'.how to accomplish my goal here?
NetShareAdd API from a VB.NET application (.NET version 2.0) and although I can get the API to just create a basic shared folder I now want to create a shared folder and specify its Share permissions (not NTFS permissions) as well, which means I have to pass in a SHARE_INFO_502 structure rather than just a SHARE_INFO_2 like I was previously doing for creating a basic share. I have spent over 5 hours solid just trying to get this working and am getting to the point now where I really cant think of anything else to try.I've encountered several problems whilst trying to make this work but the one I am finally stuck on is this: When I call NetShareAdd it returns the error INVALID_PARAMETER and the parm_ err object (which is supposed to specify which member of the SHARE_INFO_502 structure caused the error) holds the value 501. I know it is something to do with the security descriptor because if I comment out the line where I set the SHARE_INFO_502 structure's shi502_ security_descriptor field then the code works without an error (just obviously does not set the share permissons I want).I think posting all of the code here might be a bad idea as its currently over 150 lines long (yes that is only code for getting this API working...) so I'll just post my definitions of the SECURITY_DESCRIPTOR structure and the code I am actually using to call the various APIs involved: [code] Each of those API calls prior to NetShareAdd returns a non-error value in the Debug.WriteLine that is done after each one, but there is obviously an issue somewhere with the security descriptor.

Using: Visual Studio 2005.We are developing three different applications. We currently have 4 different modules that we all share among our applications. When a change is made to one of the modules, we must make changes to the other two modules.If it is possible, how do you (where do you) create a single location for one file to be shared among three different applications? Hopefully this will avoid the unnecessay task of changing a file three times.

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?
