SQL Server CREATE USER With Parameters (.net)?
Oct 16, 2010
I'm trying to execute CREATE USER with a given username (via sql parameter)
exec sp_executesql N'CREATE USER @LoginName
FOR LOGIN @LoginName;',
N'@LoginName varchar(5)', @LoginName='myuser'
Heres the code thats generating the above:
Dim myCommand As SqlCommand = New SqlCommand("CREATE USER @LoginName
FOR LOGIN @LoginName;",
ClassDatabaseConnection.CustomInstance)
[code].....
I get and error:Incorrect syntax near '@LoginName'.I think this is due to the parameters being passed as VarChar causing 'MyUser' rather than MyUser Can I not do this with sql parameters?

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?

ERROR: Could not find file 'C:Documents and SettingsuserMy DocumentsVisual Studio 2010ProjectsASP.NETuploadASP.NETuploadfile.txt This is not where the file is located. I am fairly new to .NET programming so I may have done some things incorrectly.

fileExt = fileExt.ToLower

I want both the client and server to write and read resp. at a constant rate (which can be configured on the GUI of the client) to the buffer.I am able to send from the client at 150 bytes per packet Now, I should be able to read also at 150 bytes per packet on the server too Since, both are connected through a socket, can we retrieve the socket params (set on the client size, like 150 here) from the server end, using the tcpServer object.Or is it must to send an initial setup packet which tells about these client params and so accordingly the server can continue?

I'm using a stored procedure to updateinsert data into a table using MERGE. One of the items being inserted is a VarBinary file. Now if I wish to add a new file it's just a case of using ReadAllBytes as below, to remove the file I pass DBNull. Now what if other fields are being updated but the file is not being changed? I want the field to remain untouched unless I'm replacing the file or deleting it as above. I cannot add the file via the parameter again as it may only exist in the database, unless I read it first and write it back which seems pointless. [Code]

I am writing a program where the user has to log in before the program loads. Right now I have all the users and passwords hard coded into the program. Recently I have written a Oracle function that the username and password is sent to the DB and a yes or no is sent back after comparing the passwords. I am getting the correct response back and it will display in a label (I tried it to make sure the response is correct). The problem I am having is that the program after receiving the response doesn't recognize the response so I always get an incorrect password error.
Below is my code:
empName = tbxUser.Text
passWord = tbxPassword.Text
dbConn.ConnectionString =
"Data Source=!!!!; User Id=!!!!; Password=!!!!"

have a web form using Asp.net 2.0 with vb.net. I have two date fields on the form but I would like to validate them before my gridview uses them as parameters. I am using a Dataset for the source of the gridview and two parameters called StartDate and EndDate.
Basically in the code I am setting the values of the fields to the current date at runtime. Also the date fields in the SQL Server table are datetime and I only want the user to have to enter the date and it would grab all records within that date range regardless of the time. When the user enters the two dates and clicks a button on the form I need it to reset the parameters to the enter dates and refresh the data.

I would like to make a program that generates a safe passwords for people to use. I want to make the passwords vary in length, include numbers, letters and upper case letters. I've been able to write code that prints out a random string but it includes unrecognized characters for most passwords. How would I write the code to create a random string that has parameters? (in this case upper case lower case letters and numbers).

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 need to define some roles in my program with defined permissions. Let's say the administrator can have access only to certain features. The officer in charge to certain features and the user as well. for example, I have several group boxes and the user can access one of it only. So how i do manage these permissions? What I want do is have the roles already with the defined permissions. When I create the user and assign the role, the user should get the permission automatically.

I thought I postet this yesterday but I can't find my thread so if this is a duplicate please point me at the original one. Background: I need to create a user account and Modify it's registry before the user logs on the first time. Creating the account is done by using the Winnt provider (works great). To create the profile I'm trying to use Process.start to launch a process as the newly created user. With the use of loaduserprofile property the users profile gets created and i can do my regwrites without problem.

how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])
