You're really going to have a tough time doing this. Every user get's their own copy of the user.config file. The users settings are not all sotred in a single copy of the file. The user.config settings that you refer to are stored in the profile of each user. Normally, under the path:
C:\Documents and Settings\userId\Application Data\companyName\appName_evidenceType_evidenceHash\version\user.config
The users, unless an Administrator, cannot see inside the profile folder of another user, and therefore, cannot see the settings another user has defined.

Yes, I now all this. I am using My.Settings object to store and retrieve application settings and end-user preferences. The settings are stored in two files, app.config file and user.config file (for each user), which is stored in: “C:\Documents and Settings\<username>\Local Settings\Application Data”. When we have multiple instances of the same class they share the same settings class. We can solve this problem by using the SettingsKey property from the System.Configuration.ApplicationSettingsBase Class to define multiple sets of settings. You can see this here, "http://www.code-magazine.com/articleprint.aspx?quickid=0607031&printmode=true[^]". So, in this case, I would like to retrieve all the SettingsKey saved in the user.config file and, when the user deletes one object, I would like to delete the settings values of the deleted object from the user.config file.
Thanks one more time.

I have tried the code but I got a runtime error as belo
"Error 2 Type 'System.Data.SqlClient.SqlDataReader' has no constructors. C:\Documents and Settings\user\My Documents\Visual Studio 2005\Projects\CinemaTicketing\CinemaTicketing\MainPage.vb 39 13 CinemaTicketing"
What does it mean by no instructor??

Read the error message again. It's talking about a constructor, not an instructor.
You can't create an SqlDataReader object by using the new keyword, as there is no public constructor that can be use for that. A data reader is created using the command object by calling the ExecuteReader method.

There are converters on the web that will do this for you. None of them are perfect, but they can get pretty close.
Really, what you posted is very easy to convert. All you have to do is look at any of the code samples on MSDN and they'll show you a piece of VB.NET and the equivilent C# code. Just look at the patterns of each line and you'll see that the majority of code converts quite easily.

Yes it is. I sense the OP is just being lazy ( he ought to learn C# if he doesn't know it )...

i have used a primary key in all the tables..
how do i check if a record having the same values in all the fields except the primary key(of course) is being entered twice or more?

On which column you have assigned the Primary key. What is exactly the structure of your Table.

You would have to perform an SQL SELECT query on the table looking for a record with all those fields set already. If you get anything other than 0 records back, either something went wrong in the search, or there is already a record with those details in it.

thx 4 the reply to both of you..
Also,..Dave..can you elaborate on the SQL SELECT query please..?
ie could you give an example?
i think that this might help..
i have a table emp_pc (with pc_no as PK) in which all the PC's assigned to the employees are maintained..
suppose that i assigned PC001 to EMP1..how do i avoid entering another record in which PC001 is assigned to EMP1?

There isn't enough information to write the statement. Do you have two tables holding data?? Is there a relationship between them?? What do the tables' schemas look like?? What columns are these two pieces of information in (PC001 and EMP1)??
|
|
|
|

I'm going to go out on a limb and assume that you have three tables:
emp:
emp_no - PK
emp_name
etc.
pc:
pc_no - PK
etc.
emp_pc:
emp_no - FK to emp.emp_no
pc_no - FK to pc.pc_no, unique
The primary key on emp_pc would be (emp_no, pc_no), you would also create a unique index on pc_no (because a pc can only be assigned to one employee)

What kind of file you are trying to display in the Datagrid? Datagrid is for displaying the records from a database. You can use Dataset for this purpose. Or you can also display a CSV file in the datagrid.

I was wondering if this was possible....i know i can use a VB Variable in javascript using <%= strRandom %>. But it doesn't seem as easy to pass a javascript variable to a VB variable.
|
|
|
|
|
You can't. They are two entirely different runtimes that don't know anything about each other and provide no methods for communication between them. What you're doing in your code example is actually replacing the <%...%> tag with the value of the variable in the HTML. The Java code doesn't even know VBScript exists.
|
|
|
|
|
Yeah, I just used a hidden object to store the value and take it from that.
But thanks for the reply
