just wanted to ask if it is possible to have different applications sharing the same session (i.e. database session)... i'm planning on creating a web-based application and a form-based application using asp.net for web and vb.net for forms but i need to have them share sessions since some global variables will be session based and also authentication to one application should also authenticate on the other.

I have three different web applications that I made in VS08 vb.net. Each application uses a class that i continue to update (MyClass.vb), other than using Vault to propogate changes, is it possible to create a class or dll and put it out on the webserver and have each web app call that class or dll?
View 3 RepliesI have two VB projects in one VS2010 solution. The first program brings in about 60 integers every few seconds from my PC's serial port. The second program, published via Click-Once and running on my customer's PC, needs to see that new data every two to five seconds.
Is there a simple and reliable way to accomplish this, staying with VB?
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.
I want to build a main application that make the autentication process and store the loged user... Then use X and Y applications to ask the current user and depends of the user will have full access partial or none access to the app. In future a Z application could be created and will ask for the current user also. XYZ apps are lauched from Main app, when Main app is closed the others are closed and User ID data is cleared. Of course the main app will handle the log on/log off process.
- Store User ID in a Database is toooooo much for just do this
- Save the User ID in a local file like XML is a security problem
I tried to do a WCF Service but i think its not possible to send data and store in it.The other point is who to handle the instantation issue... each program will access to the same static data not create independent.
I have 5 websites running on same server and I have some sql tables that I access frequently. that was time consuming and by defining them shared I pumped them in memory. So my application is accessing those static data tables from memory quite efficiently.
But I realized I did a mistake and I occupied my memory unnecessarily while I keep same tables 5 times for each web application. Now I need to find the best way to share that table only 1 time. my options are;
1) using a local database - sql CE. my original sql database is on other server. so it makes the access slower but I can add a sql CE database(to be honest I never used it and dont know if it gives me anything) to access only these tables while they have static rows.
2) I read over forums that making a WCF using tcp binding. not sure if it will give me any advantage.
3) windows service: is it faster than wcf? programming is defiantly faster as i have experience with winservice but nor sure about performance.
I'm asking about the best way to get data from SQL Database with less than 1 sec. Really I need to know if iIused LINQ is the faster way or ADO.Net? How can I start with application like CITRIX that will be helpful to share this application after I got data. I mean any example to start create an application to share applications like citrix to share applications?
View 6 RepliesUsing any version of .NET how do you find out which zone a particular share is classified under. I am having a problem identifying if a share where my referenced dlls reside is in the "intranet zone" or "internet" zone relative to some user machine that is running my .NET application. I suspect this is a problem because I am having a problem accessing referenced dlls from a share on some machines but not others. How can I tell which zone .NET is classifying that share in so I can adjust permissions accordingly?
View 1 RepliesI was wondering if someone could tell me if this is "bad practice" or is a perfectly acceptable way to pass an object to another form.I've cut out a lot of the code to summarise what im asking.
[Code]...
Dim myRetrievedObject as myObject = Module1.returnSavedObject()Is this a acceptable way of passing an object between forms or is it a completely bad idea?Ideally i would like to be able to "add" further objects to the initially created object in Form1 but then on reloading of Form1 , retrieve the new version of myObject with the newly added objects within the myObject class.My initial thinking is this creates an almost session like state for the initial object. So you can use the same object over all 3 forms or more and just simply add to it like a shopping cart type of functionality.
A thing which i've discovered with vb2010 is that you can't share files like a form or something that way it comes at least. If you attach a form or usercontrol from a different folder it will automatically copy it into the current project folder and then save to that. How can i stop vb from doing this? It won't always be but in this case i need to share a few forms among multiple projects and it would be a royal pain to have to copy them each time manually.
View 4 RepliesI'm writing a small software similar to the calculator in Windows, the calculator in Windows has a menu bar; in the menu bar, you can find "scientific" and "standard" mode; once you select different mode, your form will be changed, but the two forms still share the same menu bar.
I want to create the same effect of this:
1. Two forms, only one is visible at any time
2. The menu bar on the top of the two forms should be shared between these forms

I have a program that are multiple thread. Each thread calculate some data independently. however, they will need share a hashtable which controls a hardware resource. because the resource is limited, so, it may need lock the resource for a thread, and then release it when thread is finished. and the resource can not be reused immediately, will have to wait for some time, say 5 or 10 minutes, for the device to reset.
View 3 RepliesGreetings, I'm a little bit confused about SQL Server Compact behavior.I have a small app that uses a small sdf file located on a network share.The problem is that while the app itself is working perfectly well using the connection string that points the location of the sdf file on a network drive, when I try to open the same sdf using the Server Explorer I get this error:
SQL Server Compact does not support opening database files on a network share.Obviously, if the app IS working it does indeed support network shares, then why Server Explorer cannot open it?
I copied the database file to a local drive but it's not very convenient. What might be the problem?
I've been struggling for hours now to get some working code to list the share permissions of a remote share. I've got WMI code which uses win32_share which lists the shares and path and it works great. I"m now trying to add in a routine to get the share permissions as well.
I've searched just about every site for some sample code and can only find some C# (I think) code.

4. I've been working on an application for a week now, but suddenly I can no longer access my Design View(Shift-F7). All my codes are written on the [form name].Designer.vb. I can still view my codes but I cant access my form layout. On the solution explorer, my forms no longer have the 'form icon'. When i press Shift-F7 nothing happens. Right-clicking the form on the solution explorer doesn't show 'View Designer' option. How can I fix this?

I have one small problem on my app, here's the deal, when I run my app that have a button for "load playlist" and when I click on file>options my app is looking for settings.xml (created before by the same app) on the same folder from where I loaded my playlist. Load playlist button is on my Form1 and Form4, and settings is on my Form6, and this happend every time I load anything, open anything, so my app remembers last opened folder. Is there any way that I can return my path to apps path? I need to mention that this applies only to Windows XP, idk why, because on my win7 it works just fine.
