Using Syntax - Assign The Right Side Of Cnn To Cnn Using An If Statement?
Oct 24, 2010
Im developing in VS 2010 Pro, VB.
Is there a way to use the following statement, but before executing the Using statement, assign the right side of cnn to cnn using an if statement?
Using cnn As New Data.OleDb.OleDbConnection(My.Settings.ABC)
For instance, I would like to use an if statement to determine which My.Settings to use similar to:
CODE:
Then, after the If statement, use cnn in a Using statement.

I need to assign a varible in a while clause. I.e., i would do it in php like this: while (!is_bool($char=$this->getChar()) in every loop, the function would assign $char a value, the is_bool function would test it, and the code INSIDE the while clause would have access to that $char.

I have a class with a static list of keys, and I have a static method called Remove() that removes a key from that list.Now what I understand from the contracts post conditions is that as the programmer of the class, I guarantee that the current public method does something specific, in this case : removing the element of the list.
Here's what I've written:
private static List<Keys> m_usedKeys; // private list of keys
public static void Remove(Keys _key)
{
[code]....
What I'm trying to "Ensure" here, is that the Remove() method removes the key for real from the list (Yes this might be a trivial example, but I get the error there.)when I write the Contract.Ensures() line, VS2010 gives me the following error :
Error 3 Detected expression statement evaluated for potential side-effect in contracts of method 'LibJungleTimer.KeyBind.Remove(System.Windows.Forms.Keys)'. (Did you mean to put the expression into a Requires, Ensures, or Invariant call?) C:UsersJoelDocumentsProgrammationJTJungleTimerLibJungleTimerKeyBind.cs 51
I think this error says that the expression m_usedKeys.remove(_key); has a potential side-effect. In fact, it has a side-effect, it removes a key from the list!If I try to write something like this instead :
Contract.Assert(!m_usedKeys.Any(x => x == _key));
well it compiles fine.

I have a multiple-value-single-string as a parameter field in a report in Report Builder 3.0 (e.g. 20124, 20125). Now I want to split up this string, and show "Summer 2012" instead of "20124" and "Fall 2012" instead of "20125. I am using Visual Basic. Here is my two functions I have made in Report Builder 3.0 custom code. The error is in the second function in the "If Right(yearterm)..." line. It gives me a syntax error. If I write "String.Right" it gives me the error: "'Right' is not a member of 'String'". If i take out the whole "If statement" the report will run but "20124,20125" gives me this: ", 2012, 2012".
Public Function SplitParameterValues(ByVal parameter As Parameter) As String
Dim result As String
Dim a(0 To 10) As String

I am getting a syntax error for the code below.I am trying to create a user in the mysql database and add their information to a datagrid control all in one button click using two statements; one to create the actual user, and one to add the user and their additional information to a table on the database and then refresh the datasource which will display the new user's information in the datagrid control.
If anyone knows where i went wrong please feel free to critique my code and let me know; or simply offer more efficient alternatives to what im hoping to achieve.
For those of you that must know, i am running the latest version of MySql server, MySql Workbench, and Visual Basic 2010 Express on a windows 7 based laptop. I'm writing this program in VB.net.

I am trying to execute a command that inserts a row but I keep getting the error "Database error Syntax error in INSERT INTO statement." What am I doing incorrectly? I know for Ole Db refers to the parameters by sequence and I've done in the correct sequence. I left out the ID since it is auto generated could that be causing a problem?

Dim strExpr As String strExpr = "Date > '1/1/00'" Dim foundRows() As DataRow ' Use the Select method to find all rows matching the filter.foundRows = t.Select(strExpr) Dim i As Integer ' Print column 0 of each returned row.
