I have about 4 different tables with the exact same column names. What I would like to do is select the top 4 records out of all of these tables combined ordered by date (as date is one of the columns that they all share).

I just got into VB 2010 with SQL 2008 Server Report. I was able to create a report as my wish and it's vieable via direct url (URL). But I want to pass login Information and Selection parameters to the report. But I don't want to pass them thru URL, So I want to load them from the application (winform) and launch the report in iexplorer.

I'm trying to execute CREATE USER with a given username (via sql parameter)
exec sp_executesql N'CREATE USER @LoginName
FOR LOGIN @LoginName;',
N'@LoginName varchar(5)', @LoginName='myuser'
Heres the code thats generating the above:
Dim myCommand As SqlCommand = New SqlCommand("CREATE USER @LoginName
FOR LOGIN @LoginName;",
ClassDatabaseConnection.CustomInstance)
[code].....
I get and error:Incorrect syntax near '@LoginName'.I think this is due to the parameters being passed as VarChar causing 'MyUser' rather than MyUser Can I not do this with sql parameters?

I want both the client and server to write and read resp. at a constant rate (which can be configured on the GUI of the client) to the buffer.I am able to send from the client at 150 bytes per packet Now, I should be able to read also at 150 bytes per packet on the server too Since, both are connected through a socket, can we retrieve the socket params (set on the client size, like 150 here) from the server end, using the tcpServer object.Or is it must to send an initial setup packet which tells about these client params and so accordingly the server can continue?

I'm using a stored procedure to updateinsert data into a table using MERGE. One of the items being inserted is a VarBinary file. Now if I wish to add a new file it's just a case of using ReadAllBytes as below, to remove the file I pass DBNull. Now what if other fields are being updated but the file is not being changed? I want the field to remain untouched unless I'm replacing the file or deleting it as above. I cannot add the file via the parameter again as it may only exist in the database, unless I read it first and write it back which seems pointless. [Code]

I need to select all the comboboxes on a form with a for each loop. I have about 19 comboboxes and I need to select each one. I tried to do
for each box as combobox in me.controls
But that gave me an error and i now tried this:
for each box as control in me.controls
if box.name.contains("ComboBox") then
...
end if
next
That selected only the comboboxes but the problem is i need to access some data that is specific to comboboxes (aka the selected item(s), if its blank) but those properties are not present since "box" is a control, not a combo box.

I am placing 2 of these on my form and want to do the following:
1. When the control is not Focused and the user clicks inside the control, I want to highlight all text within the control. I expect to use SelectAll() to accomplish this.
2. When the control IS Focused and the user clicks inside the control, I want standard actions to occur; i.e., the user can click-and-drag to highlight, double-click to highlight,
3. When the user leaves the control (clicks on something elsle), if the control is empty, I want to populate it with pre-defined text. If it's not empty, leave text as-is.
I'm having problems, though, with figuring out #1 and #3. I have tried Enter/Leave, GotFocus/LostFocus to no avail. With Enter/Leave, the text will highlight the first time a user enters the control, but I can't seem to get the program to think the user has "left" the control. That is, the "Enter" code will not fire again.
I also thought about using the Click event, but I don't want the SelectAll() code to fire for EVERY click in the TextBox controls.

I'm writing a query to select all records that has any part of parameter. I have one table called Employees. Some people have name like this: John David Clark If the parameter is
[Code]....
I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

I have a typical data entry form to show one Customer. All textboxes, controls, etc. are bound to a BindingSource.
Clicking a button, I pop up another form with a DataGrid to show all Customers in a table, this way:
VB
Sub btn_Click
Dim frmPopUp As New frmSearch
frmPopUp.BindingSource1.DataSource = Me.BindingSource1
[Code].....
How can I populate the fields in Form1 selecting a row of the grid in frmSearch?
What I need, is to synchronize the databindings (I think).

I have a TreeView that I am using for display purposes only. I don't want the user to be able to select any of the nodes. Setting the enabled property of the form to False doesn't suffice since it changes the entire look of the nodes.
I tried canceling the select action in the BeforeExpand event. It kind of works. It selects, then de-selects the item. I'm going to play around with other events to see
