Boolean Not Saving New Values?
Dec 26, 2011Having a little issue with my boolean statement. It is not changing the value to true after you click it. Its a basic function just not working correctly and Im pretty stumped on why. I mean its a simple yes or no concept. The button is on or off is the basic concept.

VS 2005 Using The Multiple Boolean Values?
Jun 29, 2010I have code like the following:
Dim Flag as Boolean
Flag = Function1ReturnValue
Flag = Function2ReturnValue
Flag = Function3ReturnValue
Now ideally 'Flag' should only have a true value if all three of the functions returned 'True', but as it stands now it won't do that. There needs to be an 'and' or an 'or' or an '&' or something like that, but I'm confused as to what needs to be.
Asp.net - .NET Entity Framework With WHERE Clause And Boolean Values?
Oct 17, 2011I'm pretty new to MVC and the Entity Framework, but I'm sure this should be straight forward. I've got a class with a boolean "Active" flag. I then have a function that returns the results by date descending. All I want to do is ensure that only active records are returned. Should be simple, but it fails with the following error:
Error 13 Overload resolution failed because no accessible 'Where' can be called with these arguments: Extension method 'Public Function Where(predicate As System.Func(Of Review, Integer, Boolean)) As System.Collections.Generic.IEnumerable(Of Review)' defined in 'System.Linq.Enumerable': Value of type 'Boolean' cannot be converted to 'System.Func(Of PowellCasting.Models.Review, Integer, Boolean)'.

Querying/Displaying Boolean Variables From MS Access?
Jan 14, 2011I am querying the MS Access Database to display the results in a datagridview. This is my
Dim ConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=data.mdb"
Dim SQLString As String = "SELECT * FROM Groups where Selected = Yes"
Dim OleDBConn1 As System.Data.OleDb.OleDbConnection = New System.Data.OleDb.OleDbConnection(ConnString)
[code]....
The variable Selected from the query statement ("SELECT * FROM Groups where Selected = Yes") is a Boolean in the MS Access Database. However, this statement returns empty result even though most of the values for Selected are Yes. In the access database however, if I enter a 'Yes' for the value of Selected, it shows up as -1 and 'No' shows up as 0. So I even tried changing the query statement to ("SELECT * FROM Groups where Selected = -1") and also ("SELECT * FROM Groups where Selected = 'Yes'") but none of them work. Can you please help me fixing this query because I can't change the database?Also if I change the query statement to ("SELECT * FROM Groups"), then all the data shows in the datagridview, however, the values for Selected column do not display. Instead I see check boxes and I can't click them. How can I display the values correctly?
VS 2008 What To Name Boolean Data Member And Boolean Method
Nov 17, 2009From what I read it is a good convention to name a method that returns a boolean value with the prefix of "is" or "has". So in keeping with this convention I am trying to name a method in my program with this prefix but I am running Specifically I have a class called Day. It is a simple class with a few data members and one method that returns a boolean value of true or false. The name of the boolean variable is isSpecialDay. This class has a method called isSpecialDay which takes the date of the day, applies some criteria to the date and then sets the variable isSpecialDay to true or false. My problem is that the boolean variable is named isSpecialDay and so it the method. What should I do?
Public Class Day
Private TheDate as String
Private DayName as String

Jan 6, 2011This may not be the place to ask this, if not, you can move this post to the SQL forum but I have an application that I'm building which pulls dates from a database.

I have tried switching the procedure to return 0 if the tag exists and 1 if it does not and it still returns 0 despite the exact same testing conditions. I have also returned the actual select query and it has complained of the Tag "news" (my test item) not being an int on execution showing the select itself is definitely properly formed.
