Consider a process, in which multiple Application domains are created. Can we share a single static field across these Application domains or can we pass this static field across these application domains? How does CLR handle this?
View 1 RepliesI 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 a field which is static and readonly. The requirement is that the value should be allocated to the field at the login time and after that it should be readonly. How can i achieve this ?
public static class Constant
{
public static readonly string name;
}
I've got a set of static "enumeration" classes that I'm using to hold meaningful variable names to represent meaningless code values I receive on an input file. Here's an example of one.
Public Class ReasonCodeValue
Private Sub New()
End Sub

How to start vb.net application from a shared file in LAN I mean that the application is installed in my PC but I want other users to get access to this application using my shared file.
View 8 RepliesMy problem relates to executing an application located on a network share and getting various security exceptions in trying to do so. By far the greatest number of replies to this sort of problem relate to creating a new Code Group under Runtime Security Policy in the .NET Framework (v2 in this case) Configuration tool. However try as I might, and I've spent hours, trying various things with the config tool (and with caspol), I just cannot get my app to work.Still fails on things like reading command-line parameters and displaying a web page in a WebBrowser control or firing up a browser using Process.Start. In fact I've regressed to creating a VB6 version for this particular task as time is off the essence. Which works fine! As I mentioned lots of people have posted on this topic and not s few of them seem not to have resolved their issues either. So I was wondering if anyway had come up with a definitive solution for this problem which, in my case, seems to affect XP machines only? Seems to work OK on Vista, 7, 2003 Server, etc - although I haven't run exhaustive tests in these environments.
View 1 RepliesI developed a Visual Basic Program in my laptop. I can run the program form my C Drive and works perfectly.
Then I put the program in a Share Drive and:
1. If I run the program from my laptop but in the Share Drive I get this Error[url]...
2. If I run the program from my desktop and the Share Disk it is works perfectly.
3. If I run the program from a different user desktop and the Share Disk I get this error[url]...
I suppose it is a Security Issue or something like that but I am not totally sure and I do not know how to fixe it.
I've created an application (a simple calendar app w/vb.net) for my own use and would like to share it with you guys. I don't want money for it, just for the fun of sharing, and maybe get some feedback on it, not regarding the code, but the usability and concept.
However, this might not be the right place, as this forum is more about getting help on specific questions regarding code.
I've looked at codeproject.com, but it seems it's about presenting particular topics concerning code.
Does anyone know of a good place/forum to share and get feedback on finished applications?

View 2 RepliesAny 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.

View 7 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?

I'm having a problem connecting to a MySQL server over two different trusted domains.We're developing an app for internal use and have been using MySQL till now. It's a desktop app written in vb.net.Up until now all the users were on the same domain and there were no issues. Just recently there was an higher-level decision to split users in 2 different domains for various reasons.The problem is that users from the new domain cannot access the server. If that helps, I was told by the administrators that the users from both domains are trusted. Both machines are running Windows Server - 2003 and 2008.The server port is open, the grants are all in there(base_class@%) but upon attempt access denied for user base_class@datablock2.

I created a project in flex builder with application server type set to none. When I debug, I can access the web service from my local machine thats on a site [URL] When I upload the flex app to [URL] it works great.But, when I upload it to myapp.mysite.com/myapp.html it wont access the web service.
P.S. The WS was created with VB.net, and when I create a flex project with application server type set to .net, it wont access the WS from my local machine this is my crossdomain.xml file
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>

My guess is that it isn't a flex problem, but a .net security feature... wich I don't know how to configure. .NET won't allow apps to use it outside of its own domain.
The code below tries to clear the cookies for all domains once a user logs out of the system. For some reason, only the last domain in the array is cleared. Why does this happen?
For example, if I change the size of the array to 4 and then change the for loop to only go to 3, then it only logs me out of y.xcv.com.
As a sidenote, I have this loop working on a different server that uses a slightly different function to clear the cookies.
Edit: Code updated per suggestions below. Now it fails on the "as HttpCookie" line. Do I need to include some library?
Dim aDomain(12)
Dim ESidCookie, WIdCookie, EBidCookie, TSidAccessCookie, PSidAccessCookie, SSidCookie As HttpCookie
