I have a form(EmailContacts.vb) which contains a datagridview and a button(btnAdd) to add the data to a textbox of another form. My datagridview consist of 3 columns; CustName, Email and Selection. Selection column being the column with all the checkboxes. Everything is working fine and i can display data from the database on the datagridview properly.
The problem is how do i add a 'Select All' feature such that when the user clicked once on the 'Select All' checkbox, all the checkboxes in the 'Selection' column are selected?
These are my codes for the form:-

I have two DataTables, PersonInformationDataTable on which i only know about a "CityName" field, and another CityInformationDataTable, which has a few constant fields and i do a query like
ResultOfQuery = From person As DataRow in PersonInformationDataTable
From CityInfo As DataRow in CityInformationDataTable
Where (person("CityName) = CityInfo("CityName"))
Select ?? all person info ?? , Country = CityInfo("Country"), Tongue = CityInfo("SpokenTongue")
I would like again all the person fields with their values in the enumerable result.
the result would be like : name=. I don't know how many fields or the fields name of PersonInformationDataTable in advance. With a SQL Query, i could write a string with a loop on CityInformationDataTable columns and have a custom select string like : "Select Name,

I have a month and a year dropdownlist which give me the following string 01/2012 The date format in my db is "2012-01-01 00:00:00" but when I select an individual date and put it in a message box it converts to "01/01/2012"
I've altered my select statement below to reflect the converted date. However Im still not given the correct details. Any ideas? Is there a particular format that I need to use when dealing with a timestamp field? Can I even use the "Right" function in a select statement?
Dim newRecordDate As String = val1 & "/" & ComboBox2.SelectedValue Dim sql2 As String = "Select CatA, CatB, CatC, Cost, Currency, MarketingCode, Comment, RecordDate from vw_tblP_Usage_Details where puid = '" & puid & "' right(RecordDate, 7) = '" & newRecordDate & "'"
My LINQ query:
Dim groupedData = (From p In pData _
Group By p.TruncParam Into Group) _
.SelectMany(Function(g) g.Group) _
.Select(Function(d, idx) New With { _
[Code]...
When the TruncParam changes, I would like the index (idx) in the Select clause to reset to 1. So, in the list above, the Index should be SOLUB0001, SOLUB0002, INSOL0001, INSOL0002...CLRES0001, SUMCA0001, SUME0001.
How should I alter the LINQ query?
I am using VS2010 windows application , SQL server 2008 express at backend.I am designing a windows form with fields to search records in database.Say there are 3 fields in the form :
1) material no 2) material group 3)creation date the corressponding table in database with above fields is " Material_master" User can search materials in the database by entering any of the above fields.No I want to write a query where if user doesn't enter anything then my query should work like
"select * from materialmaster "
if only material no is enterd at screen then
"select * from materialmaster where MatNo = materialno "
if both date of creation and material no enterd then
" select * from materialmaster where MatNo = materialno and Date = creationdate "
In other words , field with no values in it should not be accounted in the where clause. Only one query I want to write.How we can achieve this in VB.net windows application?
I have a LINQ to sql statement that joins 2 tables. I would like to add a order by clause on one of the columns. However the order by clause does not seem to take effect at all. right syntax in VB.net to achieve order by in the following:
Dim query = From dtIt In dbsomecontext.mytable
Join dtIl In dbsomecontext.anothertable On dtIt.ItemID Equals dtIl.ItemID
Where dtIl.IsAvailable = True
Order By dtIt.manufacturer
[Code]...
Say I have this in VB.NET:
Dim executeB As Boolean
Select Case myVariable
Case "a"
'some code
Case "b"
'some code
Case Else
End Select
If myVariable is "a", control will go into the first case statement. Now let's say if myVariable = "a", but inside a's case block, I find that executeB is true, is it then possible to jump to the second case?
I'm building a dynamic query in my ASP.NET MVC project by the following: [code]Where basically the strWhere is a string that I build up a dynamic filter depending on what the user selects to search on.This works great until I need to add a date comparison to the date clause.[code]Which will end up as:"SELECT VALUE userInfos FROM MyDBEntities.UserInformations AS userInfos Where userInfos.BirthDate <= 10/09/1992"..But when i try to execute the query with the ToList whenever a date is in the where string i get the following error:The argument types 'Edm.DateTime' and 'Edm.Int32' are incompatible for this operation. Near WHERE predicate, line 1, column 103.
View 2 RepliesI am trying to read data from an excel sheet but there is an exception saying that no value given for one or more required parameters which I don't understand. Here is my code upto where the error is pointing to:
Dim MyConnection As System.Data.OleDb.OleDbConnection
Dim DtSet As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The exception points to that last line MyCommand.Fill(DtSet) which shows me that there is a problem with my select statement. Previously my code reads the data and displays it without the where clause in the select but when I added the where statement so that it can only read data from rows where the column I has a value equal to 176, it instead gives an exception that shows that some required parameter is missing a value?
i'm doing a desktop application using VS2005 with MSSQL 2005. i have a problem with the where clause in the update statement while selecting the listbox item. this is the code for the listbox in load page:

and this is my update query in the delete button event handler: mySQL = "update Appointment set recordStatus = 'deleted'" how do i put in the where clause in when i have 4 columns in the listbox? so can i do this with listbox or have to do with datagridview?
one of my stored procedures updates a combobox using paramaters.
1) StudentID as the value member and 2) StudentType as the display member.
I want to add the item ' Please select' as index 0 and read that this could be done through SQL statetment union.

I have a datagridview control on a form that I'm trying to select programmatically. My problem is, it's selecting the row in the grid when I use
Datagridview1.rows(Index).selected = True
However there is a margin on the left side of the datagrid that only get's the focus (or the little triangle identifier) when I click the row with my mouse. How I can have this row fully selected using code. When I try to run another function of my form it's crashing because the datagridview is not fully selected.

I'd like to know how you can actually select(highlight) a program from a list of programs displayed in a list box in Windows Form. I've done research and most results end up with openFileDialog condition or have to manually type the directory path. But what I have currently is the display of a list of programs in a list box(like Add/Remove Programs) but I'd like to have the user launch it upon double-clicking or clicking on a button(after a program is highlighted).
In short, it's like selecting a program in Add/Remove Program but instead of the Uninstall button, I want it to be a Launch button. I believe I already have the executable path behind the codes with the registry so I just need to know how you can select, and launch.
(Below contains an example of the kind of code I'm having)
