C# - ASP.NET Development Server Permissions And Network Resources?
Sep 17, 2010
My ASP.NET 4.0 Web App is unable to access Network Printers, while debugging on VS 2010. It can access local printers. Seems like it may be a permissions issue. Since VS2010 Debugging runs on ASP.NET Development Server, it must be running under the account I used to log into Windows, right? Does that user need to be added as an Admin in that printers users? Is there any account that I can impersonate to get this working?
I have various projects that use reflection to access and invoke private or internal members in some of the framework classes. These projects all work fine on my machine (running visual basic express 2008), but are they guaranteed to work on another machine, or, say, over a network? I've had a look at Reflection-Permission, but I'm not sure if I need that granting to me or if I grant it to my project!
I currently have my resources (images) in C:inetpubwwwrootimages I also have the images in the same location on my production server. How can I set it up so that I don't have to constantly sync up the folders? Seems like an easy thing but I'm not sure..
I have created my site using ASP.NET Personal Starter Kits 3.5. I use Visual Studio 2008 only . .with its built-in SQL Server (2005 Express) ... my database in App_Data is ASPNETDB.MDF ...I have created some of my tables also ....in ASPNETDB ..In my local PC the site was running fine ...But when I publish my site on production server it doesn't work and shows the following error
I am facing a problem in VS2008 while I am debugging the program its giving error like "Unable to run ASP.Net Development Server". I tried in Google and check the solution but it not works to me and my Operation System is Windows 7.
I am creating a multi-user application using VB 2005 Pro and SQL Server 2005.I would like to know what your ideas are when it comes to managing user permissions in regard to being able to view, add, edit and delete information in the database? Do you think I should have the end user type in the information into the VB application which then will create an SQL server user and then apply permissions to that security user or should I fine-grain the application by allowing groups to be created and then assigning permissions and users to those groups?
I am wanting to update our current windows forms security to something a lot more flexible. At the moment we have a single column in thew users table which is named 'Access_Level', this field holds an int value (1 to 4) which is then use to determine users access to certain areas of the application. This worked fine when the system was small, but the system is growing rapidly now so I think it is a good time to update the user access and possibly introduce roles.
I have an application I have developed which works great on individual PC's. However I've had some interest from a few customers that asked if I have a network version for site licencing.If my app did not save any data or write any reg entries, this might have been ok. But it does to the local computer. I also built in my own copy protection and trial function that stores data in the registry on the local computer.What would I need to do to enable my application to run on a server/network share, so that the only a serial number needed is for the server?
I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.
I have a .Net 2 solution with some asp classic pages.I get a specified cast is not valid error when I access the page on my local. Below is the vb function where I get the Error:
Public Function Retrieve(ByVal vntSeqId As String, ByRef vntPart As String, ByRef vntPartKey As String, ByRef vntEntDate As String _ , ByRef vntStatus As String, ByRef vntOrigGblId As String, ByRef vntOrigNetId As String,
Assume a .NET class library code that, for example, writes to the Windows registry. Then this code has problem to run over internet, because default Internet policy does not give access to write to the registry.By adding a RequestMinimum statement in the assembly we can specify that the code requires permission to write to write to the registry. This will not alter the fact that the code does not have the permission, but will stop the assembly from loading; the runtime will throw a System.Security.Policy.PolicyException and identify the permission that is required.Do you now any other examples of using evidence, security policy and permissions (the key elements of code-access security) to prevent an assembly from loading on a web server?
I want to use my SQL Server DB over a network. I have setup server client applications.The thing is for my current DB, I need to give it to server administrator who attaches the DB to SQLExpress instance and only then my network computers can access that.My question is, is there any way that my vb.net application could attach this DB through code at runtime, and DB gets all rights that are necessary to access it over the network?
I can attach DB using Create procedure but for this I need to know the sa password. Is there any way that I could achieve the same goal without sa passord and sa intervention?My only purpose is to enable my DB to be accessible over the network with all read /Write rights.
I am getting this error saying "the call to the server.CreateObject falied while cheking permissions. Access is denied to this object".I get this error every time I create a new DLL after compiling my VB6 code and drop it in the component services.i am using these DLL's for the web application i am working on. Is this a DLL registration issue, or is this because the DLL is not being generated correctly. What are your thoughts on this? i have attached the error message for reference
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:
We have an VB.net application that is being moved from one box to another. It runs great on the old box. The new box is configured the same as the old one but is on newer hardware. When I run the application on the new server it complains that the adobe toolkit that we use can not be found.
PLEASE I HAVE OVER TEN CLIENT COMPUTERS. AM DESIGNING AN VB.NET WITH MSSQL SERVER 2005 EXPRESS APPLICATION THAT THE CLIENT CAN CONNECT TO THE DATABASE ON A ON COMPUTER.HOW DO I DO THAT.#ie vb.net + sql server network application
I have designed a project that connects to MsSql Server 2008. The local machine that I use to create the software is able to connect to the database but when I try connect from another machine remotely, It doesn't find the server.This is the connection string I'm using Dim Connection As New SqlConnection("Server=MyServer-PC;Database=MyDatabase;Integrated Security=True")
I use Microsoft Visual Basic 2008 Express Edition and I am begginer in computer networks. I want to make two PCs communicate via network using server/client I followed the example from this site: [URL] (VB.NET TCP Client/Server Socket Commmunications) When I run the applications server and client in one computer then is possible the client to connect with server.
I'm breaking my head over the next problem. I have 2 applications (client/terminal). the client reads out the webcam and generates an image. This image needs to be send to the terminal which can accept multiple clients. At the terminal all received images are placed in an ordered panel. The purpose of this application is to monitor multiple webcams.What i can't get to work is how to send it on the client side and receive on the terminal side.
Greetings, 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 am after some code that read several mailboxes on a particular server on the network and bring me back the date of the last mail within each one. Is this possible ?
I have a client/server chat application which I made . My question is how do I make the application work not only Locally but On any other network. I tried putting my IP in the part of creation of the client socket .
I want my vb.net application to access the sql database from another network segment.I have two network segment, the application program that I made is in 192.168.7.xx segment and the SQL Server 2005 Enterprise Edition is in 192.168.1.xx segment but that application program cannot access the sql server unless I make them in the same segment.
I am using Microsoft visual basic 2010 and SQL server 2008.I develop a small database application and it run well on my pc.I built and distributed the application to other pc on the same network, but when I run the application from other pc I got error message like this:A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)[code]
I work as an IT Administrator and manage a few Servers, Routers, VPN Connections over a number if locations. What I am wanting to do is create a vb.net app that will go out and ping say every 2-5mins each of the servers, routers, that are listed and then shows beside the Hostname a Green Circle which means online and if its a Red Circle its offline, and the screen refreshes if their is a problem or a device / service comes back online.
Then if its offline email a particular email address showing the hostname of either the server or router and which location saying its offline. If possible to make it easier to change the devices to show possible have a txt file or something like that with the Hostname, IP Address, Location.
I have 2 clients connected via a server program.When 1 client hits an arrow key, a picturebox moves on client1 and on client2.Before adding this network functionality, the picturebox on client1 moved fast with each click.Now, there is a delay of like 2-3 seconds.I know the code isn't optimal, but i'm not a networking wizard.What i'm doing is when pressing a key on client 1, it passes a text to a textbox in client 2 which then has the picturebox move in client 2 depending on the text.The slowdown occurs on client 1, which is odd because the picturebox isn't directly connected to the network code.[code]
