I'm working on a form that has a few data grid views that are populated from LINQ queries, no problem there it works as it should however that sorting does not work. After doing some reading its because LINQ results do not support sorting.As I have the LINQ results already is there a way of copying the results into a dataset or datatable then binding the data grid view to that so sorting will work?

View 9 RepliesAccess databse, On the main form I have a combo box select a table (1 of 50 table names), the subform pulls up the table and users can go to a specific record. Once they move from the subform, how do I capture the subform fields to another table. As the combo table selects from one table, the selected table is different, my primary table is linked by FKey in this "MergedTable" with FKey "TableName" and FKey "item" for each of the 50 tables?
View 2 RepliesI am working with Vb.Net 2005 and sql server database.
I have a query in sql database (qryImportpatients) - it has 4 fields: prac_no, prac_eid, pat_name, pat_yr.
I have a table in sql database (tblProjectpatients) - it has 5 fields: Project_ID, prac_no, prac_eid, pat_name, pat_yr.
Now on my form in VB.Net - I have a textbox (txtProjectID) which has a numeric value. I want to have a function which when called will insert all the datafrom the 4 fields from qryImportpatients to tblProjectpatients and also insert the numeric value (ProjectID) besides each record.
I need to code the following:
1.Connect to an Oracle database.
2.Execute a query.

I'm working with the project that require save all user personal information in one table when they login my system. The problem is too many users login my system per day ( or one user can login/out many time per day), it's very hard to manage. So, I want to add one more function which can specify one user information. My solution is create a text box and a find button to filter the user whose name in text box and copy to other table after that show that table, the problem is I don't know how to do that.
I also try the code which show below, but with that way I can't achieve my require[code]...
Another question is how can I delete all information in a table in database?
This is a problem with MS Access, but I can't seem to find an MS Access Forum, so I'm asking it here.I have a large table of just one field. The field type is Byte. I use CTRL C and CTRL V to make a copy of the table.I then compare the Source and Destination tables and lo and behold they are different at about record number 8 million.I also tried an Append Query to append to an empty table (I haven't tried a Make Table query).But, similar corruption.The source and destination tables do not end up the same. The Record where the failure occurs varies, but it is always greater than 8 million.I tried this on MS Access 2002 and 2010 (both with an Access 2002 database).
View 1 RepliesI have a table I created in SQL Server Management Studio. I had to create it there because I needed to use a function for an alpha-numeric ID column that increments itself. I then exported the table, but had to use my local server. Now, in visual studio, I have the local server connection that contains the table I want to copy to a connection for a remote server. I can right-click and select 'Copy', but I can't right-click and 'Paste' into the database I need.

View 5 RepliesIf I'm extending OnCreated for a LINQ to SQL table object, is it possible to get a reference to the data context to which the table belongs? For example, if I add a property to the data context:
Partial Class MyDataContext

I don't want the property on the data context to be Shared, because it could be different per instance. I've been pouring over the designer code to figure out where the reference might be, but no luck yet.
I have an interface 'ICRUDable' and a class called ClientAddress which implements the ICRUDable interface.
My understanding of OOP would lead me to believe that if I declare a System.Data.Linq.Table(Of ICRUDable) then I should be able to put ClientAddress's in there.
The code I have tried includes;
Dim dc As New CRMDataContext

This is kind of a two part question. I'm trying to make a very simple automated program that will run two stored procedures (one that updates, one that displays the new results) and then copies the results to the clipboard and pastes it in a new e-mail. I already have the e-mail generating and grabbing whatever is on the clipboard, but I need help with the store procedures.
Every guide I look at on Google seems to show a slightly different way of working with SQL, but I threw this together and need to know if it's working.

View 2 RepliesI have a query using LINQ-to-SQL. It queries an underlying database table Rooms. It uses Where conditions to narrow down the results, namely:
Gender.Current Occupancy < Max Occupancy Available Flag is Checked I know this should return results but it keeps returning an empty set.Code is below

UPDATE: I've verified that the issue is with the statement where sh.is_available = 1, which doesn't make sense since this is a bit field.
Before LINQ I would have my main application return the results of a SQL query into a dataSet. I would then transfer the dataset as a parameter to the external dll. Now I am bringing through a LINQ to SQL query that is returned as an IQueryable(Of vClientTable) object. I want to be able to transfer that set of vClientTable results to my external dll in order for the dll to work with the data included in the results.
I am probably doing it all wrong as well as trying to do it all wrong, but would like some advice on what would be the best method to use.
DB Query
Public Shared Function getClientData(ByVal clientID As Int32) As IQueryable(Of vClientTable)
Try
Dim r = From p In dbLINQ.vClientTable _
[Code]....
Obviously in the external dll it has no idea what an IQueryable(vClientData) object is and even if I create a dbml file and datacontext in my external project for the dll that includes the same class to the DB table/view it still says that the objects are different types.
Just when I was thinking that I had Linq To Xml sussed I'm faced with yet another error! I think if I was to understand the linq search process in general better I might have more success, so any good links regarding that are also welcome. To my problem however; using the code below:
