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 :
I need to create a Select Case statement to assign the per check processing fee:user inputs number of cks into textbox that i need to validate the input if user puts in a negative amount.
10 cents for <=20 cks written ea month 8 cents <= 20 to 39 cks written ea mo 6 cents <= 40 to 59 cks written ea mo 4 cents for 60 or more cks written ea mo.
Also, I have a label programmed to display the $10 monthly fee thats has to be included into the: Total monthly fees. Here's the coding I have so far:
Const decSERVICE_FEE As Decimal = 10D Const decTWENTY_OR_LESS_CHECKS As Decimal = 0.1D Const decTWENTY_THRU_THIRTYNINE_CHECKS As Decimal = 0.08D
just trying to save some information to excel, have set up the excel worksheet and Im trying to write to it using:[code]I think i understand the problem is because it thinks that the bracket is part of the expression or something? what have i done wrong in the syntax?

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 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?
I am trying to select a row in a datatable using the datatable.select method as described in the help files. There are several examples and here is a typical one: Private Sub GetRowsByFilter() Dim t As DataTable t = DataSet1.Tables("Orders") ' Presuming the DataTable has a column named Date. 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. For i = 0 to foundRows.GetUpperBound(0) Console.WriteLine(foundRows(i)(0)) Next i End Sub The intellisense comes up with an error on the 'select' line: "value of type '1-dimensional array of system.data.datarow' cannot be converted to 'system.data.datarow'
