Deployment :: User Error When Writing To Shared Drive?
Feb 24, 2009
I have create a vb.net app that creates an excel spreadsheet. When I deployed the app, to the shared drive, I have no problems but the user gets the below error. The user can create the spreadsheet but gets the error when writing. When the user logs onto my PC, the user does not get the error. When I log onto the users PC, I got the error. Application attempted to perform an operation not allowed by the security policy To grant the application the required permission, cintact your local system adminsitrator, or use the Microsoft .net framework
request for the permission type 'System.security.permissions.securitypermissions mscorlib
version 2.0.0.0 culture =neutral

The drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.
A customer installed my app (VB 2003) on his server. BUT when he tried to run it, it bombed because the data bases couldn't be found. I hard coded the drive in my app to "C:" and his server is lettered "E". ALSo when it comes time for his client PC's to mapped to his server to run the app, they too will bomb because they see his server as "P:"
We have a shared drive which has a folder in which we programatically store the reports we create in MS Access. Sometimes the user will lose the rights to insert the files in (write access) to that folder. But we are not shown any system generated error messages for this while adiing the reports. At a lter point of time we will come to know that those reports were not saved.I am looking for a code to check whether we have the write access to the particular folder and if not, throw a suitable error message.

In this question I'm using Visual Studio 2008. My code is quite simple, as it was used from a reference I grabbed off the web. I'm using ASP/VB.Net, IIS6.0 on a Windows Server 2003 box.I've looked at various sources online, and have not been able to piece together a proper result. The purpose of this is to list a slew of directories and their respective files, and allow the user to eventually manage that directory (such as open and delete files).
Here is my ASPX page:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="DirectoryList.aspx.vb" Inherits="VCMReports.DirectoryList" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" >
[code]....
When launching the page, the following error appears: 'V:Users' is not a valid virtual path. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Web.HttpException: 'V:Users' is not a valid virtual path.
Things I have tried:
On the server, I have mapped out the drive and the directory.Permissions seem to be properly set, impersonate is correct.If I were to list a directory in the actual directory "C:InetpubDirectory", there is no failure.I do understand this is incomplete for the Directory listing portion, this will only list files (so this will need to be modified.I have attempted to create a Virtual Directory, and the application presented the same error. On my local development machine, I have the same path created - same error. How am I able to view the contents of a shared directory and it's files?
I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:
1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.
2) A server application does some work on some text files, periodically updating the data table.
I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.
1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?
2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?

writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.
I have an app the writes to the eventlog correctly in xp. The code does not work in win7.
CODE:
I get an error about inaccessable logs:security. I get that. Run as admin it goes away. I do not want to have to do that every time for every user that runs the app. besides they may not have the rights
So I wanted to make an instance of eventlog and set the Log to write to so it does not search the logs and error out on security.
CODE:
Now i get warnings about "Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated."
How the hell else are you to set the log so that the code will work under win7 with normal user rights AND not get this silly warnings?
I have 71 places that I write to the eventlog. that may or may not be too many but that is for another thread.
I think this has to do with a third party OCX control. Below is the output when the application starts. When I install my application on a stand-alone PC or most PCs in a networked environment it runs fine. When I go to some offices that have very tightly controlled networks I have problems.
The set up won't run under the user name so someone from IT must log in as administrator. They run the set up and the application installs and runs fine. The IT person logs off and the user tries to run it and the application won't even start. An error box appears and below is the report. SCANNERLib.DLL is the third party control. Maybe there is something I'm missing when I compile. Maybe the DLL registering funny under the Admin rights. [Code]
Click-once deployments are suppose to maintain user settings, but on this one application we have the user settings are overwritten to the Visual Studio default every time we publish an update.
My deployment of upgrades to an application written in C# (.NET 3.0) consist of simply replacing an older .exe with the new one. Because that older version can currently be used by some customers, I simply rename the old version to blahblah.exe.old and copy the new one to the same folder. When the user opens up the application again, the new one loads up.
The problem is, every time I deploy a new version, the user scope settings are always reverted back to the default values.
I have a program, written in VB 2008, that I deplpoy in Terminal server, that has some user settings (scope: user) that I'd like to modify locally. By default the user settings were not even installed locally. I think they are supposed to appear in the ClickOnce data directory. Using the following thread, I was able to get the user.settings installed locally:
[URL]
basically, i set my xml file as "Content" and I set the publish status as "Data File".
With this, my settings file appears in:
"C:Documents and SettingsusernameLocal SettingsApplication DataCompanyXYZProgramNameL.exe_Url_arzmal0maveh1nnwfib245pfk13xqfma1.0.0.0user.settings"
The problem is that modifying this file doesn't affect the application. I changed some settings, restarted the app, and changes were ignored.
My freeware program launches 50 freeware programs and provides a guide for PC maintenance and health. As mentioned in another post, my program was reviewed on Sofpedia. One thing the Reviewer criticized was the fact that my program requires the user to install these 50 programs in the default locations (usually C:Program Filesx). The reviewer thinks it would be best if the user can install to any location he/she desires and my program be able to point to the proper location when launching the application.
My program requires the reading and writing to a file that is shared among all users of a system. Currently I keep this file (an XML configuration file) in the directory that my application is installed to, which is C:Program FilesSomething by default. On Windows 7 (and probably XP too, but I haven't checked), regular users cannot write to this file. While I could probably set permissions as needed in my installation program, I'd rather find a more appropriate place for this file.All users need to read and write to it. Doing some Googling turns up C:ProgramData for Windows 7, but XP doesn't create this folder. Is there a common place on both platforms? Finally, is there an environment variable I can query for it?
Not sure if this is the right Forum to post this question. If not guide me where to post... I have an Access database that I would like to be able to share with Multiple user cuncurently... I have seen it is being done but I am not sure how? Or may be I should be using SQL Express.
I have made a program that i would like to be able to move from PC to PC; at the moment i would have to change the string directories within the program for each PC i would like top run it on.
By having the user select their drive letter and type their account name into a text box could this be implemented into a directory.
Below is the code, as i was hoping it was coded (lol never is tho).
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Filename As String = ("*.torrent")
I use the following code in order to check if certin user exists in the DACL:
Dim l_managemantObject As ManagementBaseObject() = CType(securityDescriptor.Properties("DACL").Value, ManagementBaseObject()) For Each mObject As ManagementBaseObject In l_managemantObject l_name = CType(mObject.GetPropertyValue("Trustee"), ManagementBaseObject).Properties("Name").Value.ToString If CType(mObject.GetPropertyValue("Trustee"), ManagementBaseObject).Properties("Domain").Value IsNot Nothing Then
I am getting an error when trying to move my ASP.NET application from VS2010 to our IIS 6.0 webserver. The error happens on the first time the app tries to make a new SQLXMLCommand Object on the login page. When navigating to the login page and entering valid credentials I got an error saying a null reference exception was thrown. Investigating into the exception we were able to determine another exception was being thrown and caught, causing the null reference exception later in the code.
The Corresponding line of code throwing the exception:
New SqlXmlCommand(conn.ConnectionString & ";Provider=SQLOLEDB.1;")
The exception causing the problems below:
Retrieving the COM class factory for component with CLSID {83D0FC3E-8B31-4B35-A1B2-346BA3954514} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))."
[code]....
Looking further into the problem, the exception is only thrown on the Web Server. No exception is thrown if I am using localhost. I though I may be missing a reference to Microsoft.Data.SqlXml.dll as it was working localhost and not on the webserver. I tried fixing this by included the dll reference in my deployment project and making sure it was added to the bin folder, but with no avail.
Edit:SQLXML 4.0 was not installed on our webserver, it was part of the baseline installation of my machine.
I'm using VS 2005 and have managed to get my application to run fairly robustly. Now it is time to deploy it and let the rest of the group use it.
File Add New Project Setup & Deployment Setup Wizard
I double click Setup Wizard and I get: "Catastrophic failure (exception from HRESULT: 0x8000FFFF (E_UNEXPCTED)" I've googled a lot of references and read through them but none of them seem to be applicable to my case.
I Have a BIG problem. I make applications on Visual basic 2010 and of course use clickonce. when another computer wants to install an application (From the mediafire in a ZIP folder) the user extracts the folder, launches either the "Setup" or the ClickOnce application and then selects install and the following error message appears:
"Unable to install or run the application. The Application requires thaat assembly Microsoft.VisualBasic.Powerpacks.Vs Version 10.0.0.0 be installed in the Global Assembly Cache (GAC) First. Please contact your system anministrator."
When i am running my application on my machine at that there is no problem but when i am running on diffrant machine at the time login failed is occurring
i create and finish my program using vb.net 2005 with database sql server2005 i did a setup package including .net fram and sql server coz other pc's which i want to install my prog in it doesn't have sql server in it. thee setup complete successfully but the problem is my programe start with a login form and that form read from a table in my database so after i install my program in other pc and try to enter by write a username and password i already use it in my pc when i creat the pro it gives me an error that i can't reach to the database and its not able to connect to remot computer!how can i solve this?is that mean that the program is working without conecting to the database?is my datab ase included in my setup package coz it had data and my programe open and work with that data?what if i have a server and that server has sql server 2000 is that will affect my program?is it better to install my program in to the server then connect other pc's to the network?
I am not an expert in using vb.net, but I am trying to make my vb.net project accessible to others. I've done it before (about 5 years ago) with another program. This program is basically the same just for a different product line for us. I have all the files on a server. I published everything to a directory on the server...the directory is in the same spot as the other directory. I checked all of my project properties and have now made sure they are the same as my other project. The publishing works fine. But, when I try to run the setup.exe or the .application file, I an error message that pulls up a log file. I've looked all over and found similar log files, but no solution that seemed to work. Here is what the log file is telling me. Any help would be great. I am thinking it is something simple...remember I am not an expert. And, I know I got the other one to work a few years ago when I moved it from visual basic 6.0 to vb.net. I am using Visual Basic 2008 Express Edition to work with my project.
"Error 2 An error occurred while signing: Key not valid for use in specified state." I found this solution on the internet but I have no idea how to do it."Delete all data sources in the Server Explorer and add them again. Run the wizard again."
I am getting the following error on a users machine who is running XP method not found 'system.string system.windows.forms.openfiledialog.get_safefilename Do I need netframework 3.5 ?
