View 1 RepliesI have two tables Employees and CafeLogs. Some employees can be cashiers and also customers at the Cafe shop.
Table structures:
Employees: EmployeeId(PK) , FirstName, LastName
CafeLogs: LogId (PK), CashierId, EmployeeId, Value, => CashierId and EmployeeId are the data from column EmployeeId of Empoyee table
Table relationship:
Employees 1:N CafeLogs (CashierId (FK))
[code]....
Right now I know how to select only LogId, Employee's name, and , Value, not with Cashier name yet.
Dim query = From log In db.CafeLogs _
Join emp In db.Employees On emp.EmployeeId Equals log.EmployeeId _
Select log.LogId, emp.FirsName, emp.LastName, log.Value
Right now I have a listbox, this listbox displays surnames, when clicked it displays their address. I have a 'confirm' button to confirm the right person. And now I need more information to come up when that's clicked, giving data from another table. I'm sure I need to use an inner join but I don't quite understand how to do it

I'm working on an ASP.NET 4.0 site, which I inherited ownership of. It has a number of existing LINQ datasources pointing to individual tables. For example, to the Patient Encounter Summary table in SQL Server. The problem is in displaying the data there. It's a normalized database, so that table contains (for example) the provider ID, rather than the provider name.
It's simple enough to join the Patient Counter Summary to the Providers table (in SQL)... but how does one do that in ASP.NET? I'm not sure of the correct nomenclature, but the 'mid layer' is VB.

I have two tables, a LP_task table and an lp_Update table. I want a complete list of tasks and only updates that were posted during a specific date range. LINQ doesn't seem to support any other join criteria but 'equals'or each task. I want all tasks (left table) even if they don't have an update. (Left Outer Join)
Dim TasksData = (From t In db.LP_Tasks _
Group Join up In db.LP_Updates On t.ID Equals up.TaskID Into upds = Group _
From u In upds.DefaultIfEmpty _

Let's say, I have something like a table in the WebBrowser component, it's not actually a table, because the data organized in flash, but, it's organized like a table, it has like rows and columns. You can see more in the attached file. Can I transform this text organized as table into DataGridView or some another tool that serves as table. like_a_table.JPG

My application must display some data in Datagridview (status of COM ports communication) and i Used .mdb databases before for faster search and Datagridview update. How i understand Datagridview is importing data from DataTable and data in DataTable is imported from .mdb file, so i decided to make shortcut - stop to using .mdb file (data must be erased every time application start and it is useless make .mdb file and erase it every time, becouse it is increasing even when drop is used) and using only DataTable..
I want to row in Datagridview change it color to red when it's Collumn(6).text countains %error% string..
When Error in COM port is starting, i can fast find row in DataTable for that port and write information that Error accured for that port and DataGridview automatically updates:
Dim RRow as () DataRow
RRow = ds.Select("Port = 'COM3')
RRow(0).Item(6) = "Error Opening COM3"

View 2 Replies Made what I think was a tactical error by using lots of 3rd party controls that made it easy to get stuff going but resulted in carrying a lot of baggage with my apps. Now it is finally time to switch to VB.Net and I want to avoid 3rd party controls as much as possible.
The database is MS Access. Master table called GroupName, key GroupID, string GroupName. Child table is GroupCustomer, key GroupID+CustomerID. Two datagridviews, GroupName on top, CustomerGroup on bottom. I've studied the one to many videos and howto's and it is easy and works like a champ. Fill the tables, sort, filter, add, update, delete, all is well.
Top grid
GroupID1 GroupName1
GroupID2 GroupName2
and so on.....
[code]....
However, adding a third table is where I get into trouble. In the bottom grid I want to link customerID to the Customer table to pick up Name, address, city, state & zip for display purposes. I've modified the table adapter to create a select query returning the lookup data with the groupID and customerID. It displays nicely on the Fill but doesn't automatically refresh the customer lookup fields when I add or change a customerID and I can't seem to update new records or deletes. The only table in my query that I want to update is the GroupCustomer table but the query is not updateable.I've been trying to figure this out, read articles, learn, step back and think but am still stuck. how to use the controls that come with VS2010.
