Create A Single Location For One File To Be Shared Among Three Different Applications?
Apr 13, 2009
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.

I would like to know if it was possible to share data between several assemblies using the same DLL.
I'm not looking for a workaround using memory or disk files of some kind of pipes to do the job I just want to know if and how:
1 - I can run an App. referring to a DLL which contains a given shared data structure.
2 - Run another App. referring to the same DLL that will use the already loaded DLL and data instead of creating a new base instance.

VB.net newbie question: I am writing a number of console applications, all of which need to use a set of common functions and subroutines that are compiled directly into the applications, not into a separate DLL.
I assume that each separate console application needs to be a separate project, and that the commonly used functions and subroutines need to be in a separate module, but how can such a module be shared between multiple projects so that only one copy of the shared module and its code is required, without creating a separate DLL?

I'm building three web applications in .NET that will all share a users database and login information. Lets pretend that application 1 is the "parent" application and applications "A" and "B" are the "child" applications. All users have to be logged into application 1 to have access to applications A and B.
Authorization, Authentication, and MachineKey sections of all web configs are present and work correctly.
I have the correct web.config settings in all applications to achieve Single Sign On except one problem remains: what do I put in the "loginUrl" attribute of the forms tag in Applications A and B.
Assume that the url for the login to application 1 is [URL] How can I get applications A and B to send the user back to application 1 for authentication using only settings in web.config?

I'm trying to figure out how to create a single .dll file in VB.NET that will contain multiple custom controls. Basically I have a .dll / single VB.NET program that will include a custom control for a Button, a Label, and a Text Box. I've figured out how to make a single custom control, but I can't seem to get it to work if I have more than one in there. It just keeps using the one I had in there originally.

Is it possible to check a location for a file and if a file exists then create a new file (+1) in the file name? For example if there is no test file in the C:Temp folder then create a test.txt file and if there is one there then create C:Temp est1.txt and if there is a C:Temp est1.txt file then create C:Temp est2.txt and so on?
I was thinking
If Not IO.File.Exists("C:Temp est.txt") Then
IO.File.WriteAllLines("C:Temp est.txt" + 1, vbCrLf)
End If

I have been working with Visual Studio 2005 for about a year and a half but the deployment task was never left to me. So now I'm being asked at my company to build a setup which will prompt to install up to 4 applications, which can be chosen by the user using checkboxes.
All of the 4 share the same dependencies, so I created a merge modules package for that purpose. But I still don't know how can I build a single setup to install these 4 applications.

I have an application which takes input on a local machine and sends it to a database stored on a server. I'd like to be able to deploy my application over a number of computers (all on the same network), all of them updating the same database (on the network server).First of all, will this be possible without putting together a completely new application to handle all connections to the database and sorting the entries?

I am wanting to create a large amount of files all copied from a single original file. I then have a list of names in a listbox that each of of these files will rename to. However I am getting an error saying that the file already exists in the save location even though the files are saving to a totally different folder...
code below.
Dim Counter As Integer = listFileNames.Items.Count
Do Until Counter = 0
System.IO.File.Move(txtOpen.Text, txtSave.Text)

I 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 am wanting to expand my programming knowledge base and the only way I know to do that is to actually do stuff. I am wanting to write an application that performs common systems tasks from a single location. Just simple things like deleting text files, maybe displaying drive space, etc. In order to even begin to do this I have to understand more about the my.computer class in VB. Does anyone have some good info that breaks this class (and possibly related classes) down hierarchically? MSDN offers a lot of info but doesn't really give a lot in the way of explaining how certain classes are interrelated.

I'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?

Im needing to create a 2 applications that can talk to each other. One wil run on a server as the server application and others will run on workstations as clients. I want them to connect to the server app much like a chat program would work. I want to be able to send commands from the server to the workstations such as reboot, open this file, things like that. I also would like to be able to send the commands backwards to the server if needed as well. i think a chat program could be modified to do this by "watching" the message and if the word "reboot" comes through then the server/workstation would convert that to a command.

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.
