Im am writing a simple console app that will check and see that a file exists and then if does it will copy the file and move/paste the file into a new location. The file I'm checking exists as a file share on a server and I am wanting to move the file to a folder on a local machines C drive.
I'm working from my machine which is on the domain where the file exists and I'm logged in and have full admin rights on the domain. I can access the file share but when I run my app it gives an error saying access to to the file path is denied. My question is even if I'm on the network do I still need to provide username and password credentials to make this connection? If so how do I do this?

I would like to ask some advise for the best thing to do regarding with this matter. Im working with a client-server application and I should run a pdf file from the server in the client application. The file name is the only saved in the database(MySql) and the full path is in the server. What technique should i used i order to access this file in the server., I planned to use the winsock. Im working in vb.net.
View 1 RepliesAt the moment i have an access database file just sat in a folder on my employers server which every computer can see. We can all run an application i have done which we can add/update/delete records/rows on te access database.I was told that access can be temperamental if too many people are using it at once, and that i should look into changing it to a sql server database ? Can a sql database just sit independently like the access database and is it just similar code except for the connection ?

I have programs written in VB2005 accessing mdb database in server. When the server run XP, it was never a problem (at the time, the folder was shared to all). There is a new rule in the company and we have Win 2003 server, and my mdb file must be stored in a folder in the server that the administrator (not I) have installed password. And clients are supposed to access it as user only. I can ask password as administrator, but the users of my program must not have the administrator password (which I can included in my program if necessary). How can I modify my program so that it can access the database? I assume I must modify my connection string, but I do not know how. I am currently using this:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source= C:Integrity ERPPBF.mdb;Jet OLEDB:Database Password=ABC"

We are currently using Access 97 as our database. This resides on the remote farm server (which is a Windows 2008 R2 server). We are using a front end vb6 exe which accesses the back end data.Occasionally we are getting corruption to our database and we have to make sure everyone exits the software to allow us to repair/compact it. There are 2 physical servers, each running 2 virtual machines. When the user logs onto the farm using RDP, they go to one of these 4 virtual machines.We are getting all kinds of corruption, some where # characters have been inserted into the top of one table, some where the indexes are corrupted, and some where access needs to repair the database.

I want to build an application, which can remote access to SQL Server in Server Machine.I used to build one, and it also can access to SQL Server in other pc. But when i promote it to become a Server(to become a Domain Controller). My application has never access to SQL Server. I don't know what to do now?
remember: I want to build an application, which is accessing to SQL Server in Window Server(Client/Server Application).
I want to know how you can export data from a disconnected database that could be access or ms sql to an sql server database.
Here is the scenario:
I have several software in a remote sites on either sql or ms access databases as back-ends...and I have another sql server database that i want to consolidate data from the remote sites.
One solution I have been thinking about is to use email to send incremental backups of the databases to the main database using a separate piece of software and have another one on the main server to pull that data into the database.
Basically am looking at setting up the remote databases as linked servers at the main database and then having incremental backups sent by email to the main database.
I have thought of replication but the internet link at the sites is terrible.
Is that a good implementation? If yes
How do i get to send the incremental backups and get them imported?(the code)
Tools:
Visual basic 2008 standard edition..Net 3.5
SQL Server 2005.
32 bit architecture.
Is there a way to include in my solution a copy of my dataset in my solution , so I can use it in another environment without access access to my SQL server database?
View 3 RepliesI have a client/server application set up that the client sends a word file to the server and then the server converts that word file to a .TIF and sends the image back.The stuff I have now works.Say if I sent the size of the file and the actual file byte() to the server back to back, would the NetworkStream contain both back to back? This what I though would happen. So I implemented a kind of 'turn' based interaction during the duration of the conversion process.

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.

View 1 RepliesI have several programs that I wrote in Visual Basic.net 2003 that I run from a server at work. We upgraded to Visual Studio 2008 recently and I converted my code to that version. I rebuilt the .exes and tried to run it from the server. It said I needed to upgrade the framework on the server, which I did. Now when I run the .exe file from the server I get a runtime error:
Runtime Error!
Program: d:...
This application has requested the Runtime to terminate it in an unusual way. Please contact the applicaiton's support team for more information.
These programs are very important to the day-to-day operations of the company I work for. I did backup the software before converting it, so we're running normally right now, but there are modifications and upgrades I need to make as soon as possible, but cannot due to the programs crashing when I run the on the server.
In my scenario, users are able to upload zip files to a.[url]....I would love to create a "daemon" which in specified time intervals will move-transfer any zip files uploaded by the users from a[url].....From the info i gathered so far,
The daemon will be an .ashx generic handler.
The daemon will be triggered at the specified time intervals via a plesk cron job
The daemon (thanks to SLaks) will consist of two FtpWebRequest's (One for reading and one for writing).
how could i implement step 3?
Do i have to read into to a memory() array the whole file and try to write that in b.example.com ?
How could i write the info i read to b[url].....?
Could i perform reading and writing of the file at the same time? No i am not asking for the full code, i just can figure out, how could i perform reading and writing on the fly, without user interaction.I mean i could download the file locally from a.example.com and upload it at b.example.com but that is not the point.

I've found a few examples of using vb.net to access an sql database, so far none of them have worked . They all involve using DataReaders. Maybe its the fact that the sql db is not on the same machine as the application.I was just wondering if anyone had a more comprehensive example of using VB.NET to access a remote sql server.
EDIT:I've received a few helpful comments an replies already. So far my connection string looks like:
"server=sqlblah.myhost.com;uid=myuser;pwd=pass;database=testdb"
Probably also good to mention their is no editing of the tables a this point, just reading.

View 1 RepliesIs it feasible to deploy a VB.NET windows forms application with a SQL Server back end where no users have direct access to SQL Server? The idea is that there is no way someone at the client site with admin capabilities could mess up the data definition, or directly alter data. I always assumed that somebody with the client should get admin capabilities, but perhaps not.
The application will have to have the capability of creating logins, doing backups, perhaps running scripts (encrypted?) For upgrades, and whatever else a user with elevated privileges would do. I guess the application would have a hard-coded account with admin privileges for this purpose. Is this a common way to deploy an application? The application uses SQL Server Express, which is installed with the application. The database will be installed with the application.
