I am selecting two table schema in a single adapter.
da=new sqldataadapter("select * from emp;select * from emp1",con);
da.fillschema(ds,Schematype.mapped);
then i am inserting some rows manually on both tables.i want to update the dataset. so that each data table in the datast will be updated in database.how to do this? since i am facing problem that it is updating all the rows in single table.
I have a datasource linked to a table in a database.When I wnated to display this data on a form, I just dragged the datasource onto the form and it did everything for me, including the code to fill it;
Me.ProjectFileTableAdapter.Fill(Me.ProjectFileDataSet.ProjectFile)
My problem, is that this program will have multiple users, and I don't other users to be able to see each others data. So the problem with the above statement is that it fills the table with ALL the data in the datasource. How can I make it only display data that is for a specific user?Here's the code that is used to fill the tableadapter:
Private
Sub
frmViewCurrent_Load(ByVal[code].......

View 1 RepliesI am trying to get back a single from from a EF database model using the below line of code..
Dim _classRoom As classrm = db.classrms.Select(Function(b) b.Course_ID = _CurrCourse.course_ref)
Where classrm is the name of the entity and db is declared as a new entity. What I am trying to do is select a row from the entity based on matching Course_ID which in this model is a string. So that I can later use the variable _classRoom to get other items out of the same row.. However I am getting the following error:

View 1 RepliesIn my application, the user clicks a single button and the program displays each network adapter description into a message box and then gets all the ip info for the workstation and places it into a text file and opens that text for reading. What I would really like for it to do would be to display all the network adapters into a single messagebox instead of messagebox for every adapter like it is currently doing. Here is the code I have on that button. Let me know if anyone needs more info or has any questions:

View 6 RepliesI'm looking for a way to use two DateTimePicker controls to select a range of hours and minutes within one day. That is, to basically select a 'starting time' and 'ending time'.
I started with two DateTimePicker controls with the custom format of h:mm tt. I tried adding (on ValueChanged), a check that made the selected 'starting time' will become the 'ending times' minimum and vice versa, the 'ending time' becoming the 'starting times' maximum
However, that approach didn't seem to work -- I was still able to select 11.00 AM on the 'ending time' and 1.00 PM on the 'starting time'. I have a feeling that the current day of the timestamp has something to do with it (e.g. the starting time is of the previous day, and therefore is less).
I thought about changing to a combo box of preset half hour intervals throughout the day; however the minutes need to be more flexible than that...
UPDATE:
Dan's comment below answered this problem... This is the code I ended up with for reference;
Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged

View 2 RepliesTo get an id value after a table insert into an Access database you do a SELECT @@IDENTITY. I would like to know if this will work if your INSERT query is a table adapter query? I created an INSERT query for a table in the dataset designer which is working. My concern is that if I make another query with SELECT @@IDENTITY it won't work because table adapters make a new connection each time. Can someone clear me up on this?
