Problem i have is that it selects all records that have a value equal to or less than 24 rather than the records that have a value greater than 12 and equal or less than 24. This appears to be an error i am making in the use of greater and less than?
I'm trying to create a new thread and send multiple parameters as well as a delegate to report back.

After searching thru BOL and various forums, I've been unable to determine how to use a backgroundworker component with a procedure that contains multiple parameters. If I understand correctly, DoWorkEventArgs is used to pass parameters. However, all the examples I have found use only one. Since DoWorkEventArgs ends in an "s", I imagine it is possible to use more than one parameter.
View 3 RepliesI have a connection to a MS SQL database, which I understand is capable of handling multiple SQL statements in one Execution, ie
Code:
Using cmdExe As New System.Data.SqlClient.SqlCommand
sSQL = "Delete * from mytable where UniqueID=123;Insert into mytable (UniqueID, Field) values (123, 'something')"
cmdExe.CommandText = strSingleSQLLine
cmdExe.ExecuteNonQuery()
End Using
will delete from "mytable" and insert a new record all at once. This is great, but I want to expand upon that to use parameters because using string concatenation in my SQL queries is a bad idea. Now my question is this. If I add a parameter which is used in multiple SQL statements, do I have to add the parameter VALUE twice to the command object? ie, will the following code work?
Code:
Using cmdExe As New System.Data.SqlClient.SqlCommand
sSQL = "Delete * from mytable where UniqueID=@uniqueID;Insert into mytable (UniqueID, Field) values (@uniqueID, 'something')"
cmdExe.Parameters.AddWithValue("@uniqueID", 123)

There are two questions here actually...can I add the parameters before setting the command text, and do I have to add the same parameter over and over again?

I'm wanting to to make a color scheme selection feature for my program, which involves changing the foreground and background colors of many components at once. I have the components divided into groups in which all elements should have the same background and foreground.
vb
With BtnLoad And BtnSave And TbxListname And CmbProgDifficulty And TbxRptStandard And TbxQNA And BtnAddProbQ .ForeColor = Color.White .BackColor = Color.IndianRed End With
The problem is that this get's an error message saying that you cannot use "And" (or & or +) in the statement.If I just use one object at a time,
vb
With BtnLoad .ForeColor = Color.White .BackColor = Color.IndianRed End With
it works fine. I have so many objects though, I don't really want to copy and paste this with statement 50 times. is there a way to make a with statement take multiple objects?
