I wanted to create my own type that acts like the Boolean type, except I wanted to use Yes and No instead of True and False.I kind of got close but it wasnt exactly what i was going for here's what i have:
[code]...
so i have to use an integer when i dim it like:dim b as MyBool = 1 then when you look at it in the watch window b = {Yes} so i could settle for that, but with a boolean you can do this:dim b as Boolean without setting it to anything it defaults to False mine however, is Nothing. 2 things: 1. How can i get mine to default to No 2. How can i make it work like this: dim b as MyBool = Yes instead of having to use the integer this is not a requirement for anything I just wanted to know how to do it

Simple question, I have an application and dependant on whether you are in the administration system or on the public website I want to show different results. Example: in the database for a news story in the administration I may set the column value 'showonsite' to false. So I would like this to show in the administration panel only and not on the live site.
My question is, because I require the same information just with the only one column change, live site to only show true values and administration to show both. What is the most effective way of achieving this without copy paste of code?

I am trying to get true false statements to work. Each statement has its own msgbox and if true adds 1 to x. At the end i use a case function which will give the final number of x and give it a value in a textbox. What is happening instead is, if I click "no" on every Yes/No question, I get a 4. If I click "yes" on every Yes/No, I still get a 4. For car 3, 4, and 6 I want a "no" to be true. For 1,2,5,7 I want yes to be true.

I am new to programming.I am making a coin tossing program for class.It is telling me I need to create a separate method that doesn't take any arguments and only returns false for tails and true heads.Not sure if a function or a sub returns only that type of data. Also once the code is returned I can then add that to a CONST to keep a running total.If the method only returns true or false do I need to put the code in buttonclick sub to post the image of the coin in the picturebox using a if then statement? Would I also need to add the code for the print out of the statistics after the if then statement? Not asking for code just a step in the right direction.

I have tried and successfully ran the code in this thread.>>I have just been thinking about an extension method for a STRING so you couldtypesomeStringHere.IsInMicrosoftWordDictionaryand it would return TRUE or FALSEwith an overloaded version where you could optionally specify the language.Is it possibly to query the dictionary in MS Word in such a fashion? If so, how please?This may lead to me creating a word based game, it is not hangman but a word search game,ut with a twist on word search puzzles. I'm not going to give the idea away.This is what I have so far. The MODULE code for the extensions.>>

I have several custom snippets that show up when I use "Insert Snippet", and they have also shortcuts assigned to them, but whenever I try to use the shortcut directly, they don't show up in Intellisense. If I type the full shortcut and press tab, the snippet is still inserted... But I'd really like the shortcuts to show in intellisence.

How come both intellisense and compiler accepts If 3 = True Then ... in VB.NET? Even with option strict on.Does it in actuality treat Booleans as Integers, or what's the deal?

I call a function (SaveChanges) to access my business / data layer and save any changes to fields that are marked as an Add or Update and are marked to be processed. This function used to work fine up until 60+ minutes ago. What is happening is that suddenly the function is returning false. After debugging through the code, when it hits Return the local boolean is set as True but when it gets back to the calling method (and uses the return value) it is now False. As I said I went through line by line and debugged it, then I added a watch to it. The funny part is that there is one spot that sets the Boolean to false, and when I put a breakpoint on that spot it is never reached.
Here is the function:
Private Function SaveChanges() As Boolean
Dim blnSaved As Boolean = True
Dim saveableRows As List(Of DataRow) = (From d As DataRow In _listData.Tables(0).Rows _
Where Not d("Marking") = "Duplicate" _
And d("Process") = True _

I have several text boxes that I will input answers into and I want them to catch the values if they are incorrect or correct.
Example: the user will input a Letter for the answer, A or a, and I was curious to how the correct input can detect if the answer is correct.If the answer is A B C or D then no message should display but when it's some other value this message will come up.How do I use true or false in this code?
Dim dbl1 As Double
dbl1 = CDbl(txt1.Text)
If dbl1 Not 'A OR a' Then
'Display message
MessageBox.Show("Enter A, B, C, or D")

While testing some code i found something strange how vb.net (2005) is handling integer representation of true and false (or yes and no). Or at least i dont understand the reason for this.Im used to C or Java where 0 is false and everything else is true. To get to the point, here is the code: [code] And the out put is:X: 1 Y: 2x is truey is truex and y is false.If x and y or both individually true, why does it return false when you evaluate x And y.However, change the values of x and y to 4 and 5 you get this:X: 4 Y: 5x is truey is truex and y is trueJust another example, which seems to work how it should to me:X: 4 Y: 0x is truey is falsex and y is false.

i have a checkbox bound to a column with datatype character to my database... the column uses values Y and N.also, just like to add that i have tried changing the column into character of 5 byte so that it can hold the values "True" and "False" when the property bound is the property Checked. this works okay but there are some columns that doesn't use True and False like in my statement above.is there a way that i can set my checkbox to checked when the column value it is bound to is Y and vice versa.. i noticed that in the checkbox inside a datagridview has the properties TrueValue and FalseValue but i dont see this anywhere in the checkbox not in the datagridview.

Nice simple one (I Hope) to start of the day. I have got a load of calculations going on and then a set of rules being checked after the calculations. I then have 9 booleans which check against the varibles. Basically I would like an easy way to check how many Booleans are False and how many are True.
