VS 2008 Application On Shared Network
Jul 28, 2009
I have a VB2008 application that runs off a server. Users connect to the application via shortcut.
[code...]
For what it's worth, the application is targeting .NET 2.0 Framework on both the development side and package install side.
The illustration below is more for my sake than yours, but should help me explain the problem.
User A and B work just fine, but when User C and User D attempt to use the program via shortcut9(same as User A and B) the error below is displayed.
[code...]
what I can do to allow User C and D to use the application?

I'm working on my first VB2010 project, having used VB6 up to now.In VB6, I used some library functions to implement a treeview of network PCs and their shared folders.
I've been searching, but I've not found a way to get this done with VB2010.
I have found scode to return a list of all the devices local to my network....close but not what I'm looking for.

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

All i am trying to do is read and write files to a shared folder on a network in visual basic (VS 2010). I can go to the folder through windows without a problem and without being prompted for a password. However when i try to do it through visual basic, it cant find the directory. Here is my small snippet of code that i (hope) is telling me that the program cannot connect to the folder. [code] Are there any known issues with VS 2010 that may cause this? Maybe something else in my code that could have an effect? This is in my form_load event though, so it is literally one of the first things that runs.

With the help of NetFileEnum or Openfiles.exe of system32, we can get the username who has opened the shared files. Is there any API function or any exe files in any programming language like c#, vb.net, visual c++ to find out who is the user to create, rename, or delete shared files or folders on the network?

I have a web service that is currently calling the DOS command copy to put a text file to a specified network share.
This is the code:
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Imports System.Data
Imports System.IO
Imports System.Xml
[Code] .....
It appears doing this might be causing some problems and our front-end programmer suggested I see if I can output the stream "output" directly to the network shared printer specified by the SOAP request. Is this possible? This is VS 2010

On the earlier version of VB.net 2003, I could run a wizard to give full trust to a .Net application on the network. With VB.net 2008, there is no longer a wizard to do this. I did some Googling and most of the references I find refer to using Caspol for .Net 2.0. That doesn't seem to be an option .net 3.5 (I can't find Caspol in the framework folder). Does anyone know how to do this for VB.net 2008?

I have created an application which uses an sql server connection as its datasource. The problem I'm having is that the application needs to work on computer that has no network connection. How Can i change the datasource so that on runtime it can work off a machine that is not connected to a network? The datasource from the sql connection only contains one table with no data. It only needs to be updated with a target folder that can be changed to any location on any computer already written in the code.
The connection string suddenly stands as: Dim MyConnectionString As String = "Data Source=MY-PC;Initial Catalog=ImageLocs;User Id=test;Password=test;Pooling=False"

I have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

I am developing an application that has multiple forms and I wanted to know the best method to have application wide methods and functions. Currently I am using a Module with all my methods that are needed to be used across the entire application in it. However, I read at one point that modules should not be used, as they are only there to preserve backwards compatibility with older VB code. Is there a better way to have methods able to be called anywhere?

i have an multi-threading applicaton. so I am using system.threading.thread class to create thread. each threads call its own class and inside each class i am accessing webservices. I need to have status returned from each webservice. thats why I defined a shared property as list of generic object which will be updated within each class called its thread. but I have an hesitation that when I run application on the server. this shared object will be used by all instances of web application. Is it true or shared properties is used only for its own instance?

Basically i am creating a vbnet system software. I want to create a shortcut key to lock the system with out affecting the windows explorer (just my system only). Is it possible to create one for that? Or let's say create a procedure that triggers anywhere whether the focus is on a control, on a form (whether shown as normal or modal), or on any other that has the focus on it.

I currently need to build a Automation Add-in for Excel. This add-in will load a recordset from Database to Excel. I would like to have function A() that I input in Cell as a formular. This function A() call a the add-in to load the data from Database to Excel. The data should be a matrix. So that means I would like to set in Excel worksheet a range of data by just calling single function in a cell. (I am sure there should be some way to implement it)As I know if I develop a shared Add-in by VB(or VB.Net) and in the add-in, I can get an Object of Excel.Application. By this Excel.Application object, I can get full control of Excel inside the Add-in. That means if I define a sub that load datamatrix from database and using the Excel.Application object I can populate the data matrix to the Excel.
I have done much research on internet and I now have built a shared Add-in for excel. I should say this add-in works fine without invoke the Excel.Application Object that I have tested. But when I call the Add-in function that invode Excel.Application Object from Excel I got an error as below:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Run-time error '2147467262'(*)
Unable to cast object of type 'System.String' to type Excel.Application

I have a class like this:

It works, when I make getBar methods public, but I don't want to expose these unneccessarily. Why I can't call private shared methods from a public one in the same class is over my head. I'm using .net framework 4.0 in a web application.

I have an application in vb.net that runs over a network. Actually shortcut of the exe file is shared over LAN, so databases remain on one computer where the application has been installed. Everything works great except one thing. The logo of this application is saved in a database, that reports can pick to load picture. The logo file is chosen by the user, using OpenFileDialog and then saved in database. It is saved like D: Picturesfilename. jpg When I run the application from network (using shortcut that we have made to the main exe file), it given error on D:Picturesfilename.jpg because this doe not exits in the system that is running the shortcut. How to save the logo path in a way that it always finds it in application directory, when run over the network.

How difficult would it be to have my application check for user authorization over a network?
If I have a php server, each time someone starts my application it should connect to the server and check the users computer name against a list of authorized computers, possibly using MySQL.

I have a client-side app which I am working on. As I start to enhance the app, I am starting to wonder whether or not I should be building a network side app instead. My app in its current form sits on the client side and generates some text and XML files which are stored locally on the client side. The user reads/write to these files. However, I want to start working with SQL AND the processing time of my app is starting to consume resources (i.e. time and CPU) on the client side.
Can someone provide me with some highl level feedback on what one would do to make their client-side app a network app that multiple users would have access to. I realize more detail would need to be provided in order to provide thorough answer. However at this point, I really just want to understand how a network app would differ from a client app from a programminga and deployment perspective.This is not necessarily a VB question. Howevever since I am working in VB I though I would start in this forum. Feel free to move to the appropriate forum if need be.

Our company runs Windows Server 2008 R2 and as part of the normal login procedure you type your username and password. IT sets the domain when you get your PC so that is all good. So, when you open IE, the intranet sight detects that you are person XXX YYY and then logs you into the site automatically as the right person.
Now is there any way that I can do the same with an application written in C# or VB.NET. I.e., I would like the user to not have to log in as they have already done so during Windows log in, and then use the application as the individual user. This is for loggin purposes and specific rights for each group.

I've taken over the maintenance of the website (ASP.NET VB) and on one particular page I noticed the below code
Inherits System.Web.UI.Page
Public Shared UserNumber As String
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
[Code]....
My question is whether the variable UserNumber can be accessed or changed by any other user than the current one?

Any simple way of automatically updating a newer version of my application from a network share. Everything I have read pertains to an update from a web site. This is possibly a simple thing to do but as I have 6-8 users using the application I have to email them all stating there is a new version on the share and for them to copy and overwrite the existing application executable in the program filesapp directory. If this could be done on launching the program within the splash screen that would be fantastic.

I am starting a new project in VB, a card game modelled to be similar to a real card game.
I have the majority of the program planned out and have even started coding parts of it; my problem comes with the networking.This is a real-time card game (not turn-based) and I want to be able to play with real people (family mostly, so over LAN is what I'm after).
I have tried searching for code samples but I everything I have found seems more complicated than I feel is required for the task, introducing a lot of new concepts and not explaining them.
What I'm after is a simple way to exchange the information in real-time, I don't care so much for efficiency (at the moment) just ease of use - though if I need to wade through a heap of documentation I will. A perfect answer would tell me what the names of some of the controls/methods that would be appropriate are, even if it just re-affirms a bit of the complexity, you do not have to detail anything if you don't want to I just feel a bit at loss as to what exactly it is I am looking for!
