Access may not be a real database, but last time I checked, it used SQL.

This is nowhere near enough information to help you.
You're going to have to supply a better explanation of what your having a problem with. A code sample might also help.

I am trying to use a DropDownList for displaying and changing data within a database. As soon as I select a new value from the list and click the change link then look at the DropDownList selected index value in the Update_Command function it has changed back to the original value. Is there a way to capture the new value before the bind occurs so I can update the database?

If there's a FAQ, this should be on it. The answer is no. You should wrap your databind in a !IsPostback block, so it does not bind on postback, it will get the data source along with the selected index from viewstate.

I have created a custom principal class based on IPrincipal and have exteded it for additional properties and methogs such as .UserName, .UserID to return data and IsInAnyRole to accept a list of possible roles for a user. Is there a way that I can use Declarative security with this for something like...
Public Shared Sub _<br />
[PrincipalPermissionAttribute(SecurityAction.Demand, IsInAnyRole:="Role1,Role2,etc...")] _<br />
PrivateInfo()<br />
<br />
'Print secret data.<br />
Console.WriteLine(ControlChars.CrLf + "You have access to the private data!")<br />
End Sub
The isInAnyRole is not part of the PrincipalPermissionAttribute class though. Is there an easy way to write or extend it so that I can use it with extended methods from my custom principal class?
Thanks in advanvce for any help...

Dear friends
I am new in vb.net and i try to make a some sample for practice. I am using that code below
Dim cmddelete As New OleDbCommand("Delete from ANABILGI where ADI=@param1, AND SOYADI= @param2, AND BABAADI=@param3", baglan)
cmddelete.Parameters.Add("@param1", txtad.Text)
cmddelete.Parameters.Add("@param2", txtsoyad.Text)
cmddelete.Parameters.Add("@param3", txtbabaad.Text)
baglan.Open()
cmddelete.ExecuteNonQuery()
baglan.Close()
but if i try to run it it was an error (Name 'ExecuteNonQuery' is not declared)
-------------------------------------------------------------------------------------------------
but if i run that code with update statement it is working that code is also below
Dim cmdupdate As New OleDbCommand("Update ANABILGI SET ADI=@adi, SOYADI=@soyadi, BABAADI=@babaadi, ANAADI=@anaadi WHERE ID=@ind", baglan)
cmdupdate.Parameters.Add("@adi", txtad.Text)
cmdupdate.Parameters.Add("@soyadi", txtsoyad.Text)
cmdupdate.Parameters.Add("@soyadi", txtbabaad.Text)
cmdupdate.Parameters.Add("@soyadi", txtanaad.Text)
cmdupdate.Parameters.Add("@ind", DataGrid1.CurrentRowIndex + 1)
baglan.Open()
cmdupdate.ExecuteNonQuery()
baglan.Close()
Getalldataindatagrid()
DataGrid1.Refresh()
End Sub
--------------------------------------------------------------------------------------------------

Hi,
How to display the images in VB.NETDatagrid
Thanks

Hello All,
I am not sure if I am repeating the same question asked in this forum before.
Can we dynamically generate the reports, say, like an user selecting the required fields across DB tables (through a front-end), specifying the criteria -us building the SQL query- and fetching the result from the DB.
Any help on this would be appreciated.
Thanks
|
|
|
|
|
Yes, of course we can. You need to provide the user with a list of possible search fields, build your SQL from them, check for injection attacks, and run the query. Which bit are you stuck on ?

Hi
First of all thanks for the reply
i am stuck at building sql query from the fields selected and then passing it on to the reports
Can you please help me out
|
|

|

Do you know any SQL at all ? I can't give advice that's any better than what google will offer unless I know what's in the tables you're searching.

Yes i do know sql
I will give you a brief description with example
I have two different tables Say StuMaster and StuDetails
In StuMaster i have rollno,name,year
in studetails i have his rollno,addressinfo,marksinfo of eachsubject
Now i need something like selecting
rollno,name,year from master and marks of selected subjects of that year from the details table
So i will select the required subjects from the listbox and those fields are to be displayed onto the report.

Anonymous wrote:
marksinfo of eachsubject
Does this mean there's a column per subject, or are they all lumped in there ?
You want to select subjects, but that makes no sense, there's no column there to search by subject.

each subject each column
and its search by column ie subject
|
|
|
|
|
You said : in studetails i have his rollno,addressinfo,marksinfo of eachsubject
Now you say : each subject each column
What does 'each subject each column' mean ? Each subject has it's own column ? So every possible subject has a column, even the ones a student is not taking ? That's *terrible* database design.
So how do you mark that a person didn't take a subjuct, is the column null ?
All you need to do is join on the ID, and check that the subject you want to recieve is not null. But the core problem is that if I understand you correctly, your database is crap. Are you able to change the schema to something reasonable ?

its the example one christy its not the actual one actually my TL asked me to find out solution
so i made up an example for it
|
|
|
|
|
I don't get it - so the example you gave me is NOT the table structure ? What's a TL ?

Yes its not the table structure its a temporary one

Hi,
I am trying to connect to a database using VB6, ADO and Access 2000. I have a combobox with the names of all the registered DNSs on the computer. When I select a DSN from the combobox I have to retrieve some records from the DB indicated by the chosen DSN. How can I connect to the database using the DSN name?
Thanks very much for your help,
