Referrence For Address "acSysCmdSetStatus" And Other Access Objects And Methods?
Aug 13, 2010
In VB.Net I am attempting to use Office Automation starting in Access; then to Excel.I am having difficulty finding the References in VB.Net which will permit me to upgrade my VBA code to VB.Net.For example in VBA the code line: Application.SysCmd(acSysCmdSetStatus, Space(75))
In VB.Net, I cannot find "acSysCmdSetStatus." Error message = Name "acSysCmdSetStatus" is not declared
Following are my Imports:
Imports System.Data.OleDb

I always thought I understood how this works...but lately I have started really using interfaces and now things arent doing what I am expecting.
using entity framework, I have a service for each object that is responsible for interacting with the database and such....on my one service I am passing the collection of objects to my service as an icollection(of contactinfo) before I pass the object, the changetraker has the right states. however in my method, this is not the case and all states are set to unmodified.
Private Sub SaveExecute(ByVal param As Object)
Dim srv As Services.ContactInfoService = GetService(Of Services.IContactInfoService)()
[Code]....
As I said above the Me.contacInfoCollection has the right changetracking states. But Once its passed to the srv.savechanges it reverts to unmodified. I am sure its something silly I am missing...the whole EF thing can be confusing to me...

I've been wasting so much time on this. Basically I want to have a list of objects and I want to call some specific methods of some specific bjects..g.MsgBox(Instances(0).Position(0).ToString)It should alert a number that presents the X position, but it is not working... the box does not even appear and no errors.

In C# I'm calling a function on an interop class (Connection, written in VB6), which itself returns a plain object (System). Then there's a function on that object (InitialiseData) that I also call (even though the compiler isn't aware of it). var isInitialised = Connection.System.InitialiseData(path); The problem is, because that System object is returning a mere Object, I get the compile error "cannot resolve symbol". I can see why, but the same thing works fine in VB.NET:

I seem to find more and more that I declare a lot of objects or methods as Shared now but it feels like I am not doing things properly.I try to avoid doing this but then I just end up with situations where I have to create an instance of a class just to call one method that would act no differently if it was just a shared method.Basically I'm just wanting to know if there is any good reason to avoid using Shared objects/methods. Obviously I dont declare EVERYTHING as shared, but it just seems to make things a lot simpler most of the time.For example in my current project (a chat application using WCF) I have a class just called Core which houses a lot of the main functions of the client program, so it has methods such as: SignUserIn, SignUserOut, SendMessage, MessageReceived etc and it also holds properties such as a list that contains all of the currently online users. These things are all declared Shared in my program because as far as I can see there is no reason for having to do this:[code]

I have been assigned to create a simple address book in VB 2005 and have got as far as I can with it. Contact entries are to be stored as an array of objects rather than to .txt file or access database (I know they will all be lost when shut down). I suspect this is probably pretty straightforward if you know anything about VB - unlike myself obviously.
Public Class Form1
Private objContact As New ArrayList
Private Sub BtnAddContact_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnAddContact.Click
Dim objcontact(100) As Contact

Have a windows application that "got complex" and new products could use many portions of the existing application.Decided to break app into multiple projects to facilitate sharing the appropriate pieces with new products.One object in app provides a library of text phrases used in the production of output docs.Wondering if such an object should be a set of shared methods instead of instantiating it in every object that consumes these text phrases.

In c# asp.net mvc I can declare some public class like:
public class Foo {
public static string Bar {get
{return "bar";}
}
}
and access it from any html like:
<%=Foo.Bar;%>
right?Well, I have to do the same in ASP.NET MVC VB.Net but I cannot access any variable or method:
public class Foo
public Shared ReadOnly Bar as string
Get
[code]....
UPDATE:standard VB.NET puts modules in the namespace defined in your project.I had to type
MVCApplication1.Foo.Bar
how to create a module that doesn't wrap this into a namespace? Or have the view import the application namespace by default?

I have a sub (Sub 1)that passes a control to another sub (Sub2) Sub2 only knows that the control will either be a picturebox ("Pict1") or a rich textbox ("Rchtxbx").I want to put code in Sub2 that does the following if the control that is passed is aPictureBox:ictureBox1.Load("C est.bmp")However I don't know how to do this as when I type in "x" in Sub2, it does not default to the PictureBox properties and methods.Is it possible to use the name of a control and wrap it in some sort of ControlType() enclosure that identifies its type and grants access to its properties and methods?

What faster methods are available for VB to access the internet? I.e. methods which are faster than simply using VB Browser, as people make web bots which access multiple sites quickly which I would imagine meant there is a faster way.

I'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]...

There is a site that I go to that has a website chat thats located at the bottom of every page. It allows you to talk to specific people while you're online and they're online.
Sometimes when I get into a good conversation I don't want to end it. I still have other things to do though.I wanted to make a small window that I can just drag around that will allow me to chat with people easier.
I've set up pretty much everything in this program except the actual retrieving of the information from the site and the replying to the chat. I know I could do this (I've done similar things in the past) by putting an invisible webbrowser object off to the side and just run my stuff through there. But I think thats kind of sloppy.
I've read in some of my classes and books and have learned how to make simple web requests that return the results. In its case, I had to return definitions from google. I tried this on a recent project but found that it didn't the permission to access any kind of secured account whether it was logged in or not because it was "unsafe".
Does anybody know how to access a page thats been logged into through IE but without needing the sloppy methods I mentioned earlier?

I'm just getting started with Visual Studio (2005), and my aim is to write a fairly simple application in Visual Basic that will need to store some data to disk.What I really want is to be able to send the application to the end users (xp, vista, win7) and have them just be able to use it without having down download all kinds of extras. For example I'm guessing that if I use an SQL database in my application they will need to download SQl server express or some other sql downloadable?
If so is there a similar downloadable for MS Access?I'm just in the 'seeing how things work' stage at the moment and I don't want to waste time going down the SQL track just to find it won't actually work unless my users all download SQL to their machines (which they won't want to do).

I am not sure how clear my question is by the title, but I am trying to make Class methods instead of Instance methods in Visual Basic that way I don't have to waste memory and code creating temporary objects to execute methods that don't need instance variables.
I am not sure if you can do that in VB but I know you can in Objective-C by using either a "+" or "-" sign in front of the method declaration. And in C++ (at least I think, I can't remember) you put the static keyword or const keyword in front of the function.How would I do this in VB if it is possible? Or should I just make a separate set of functions that are not members of a class?
