Ok simply my code doesnt want to output the correct number. I'm working on the project euler probems to expand my knowledge in VB.net and the current question I am working on is asking to work with triangle numbers. while researching I found that a triangle number can be calculated by using the formula:
Is it possible to return more than one value from a function? Like two integers, or an integer and a boolean, or any other data type combination. I understand I could use a sub and set these values in a variable but I was wondering if I could avoid declaring more variables by using a function.
I am working on a project I would like to use a function in a class I created to return multiple values in order to populate a listbox. I wanted to use a do until loop to achieve this. I will just post a simplified example of what I am doing :
Public Function Listboxfiller Dim astring As String = "This is a string" Dim Counter as integer = 0 Do until Counter = 5 return astring Counter += 1 Loop
Then on the form I would do something like : lstListbox.Items.Add(Myclass.Listboxfiller)
What happens right now is that the listbox only gets the first value, when I ran through in debug mode I found the loop only runs once, even though it should go multiple times.
Function GetAdInfo(ByVal ADDN As String, ByVal ADCommonName As String, ByVal ADGivenName As String, ByVal ADStaffNum As String, ByVal ADEmail As String, ByVal ADDescription As String, ByVal ADTelephone As String, ByVal ADOffice As String, ByVal ADEmployeeID As String) As
show me how to return multiple values from a function? I have my function in a seperate file within App_Code and here it is:Public Function GetQuoteStatus(ByVal QuoteID As String) As String
Dim quoteStatus As String Dim con As New SqlConnection Dim cmd As New SqlCommand Try con.ConnectionString = ConfigurationManager.AppSettings("quotingSystemConnectionString") con.Open()
[Code]...
However this is all good and well for one returned value but what If I wanted to return multiple values.How do I access them?
I am pulling a date value from my database: Dim qfresho = From p In dbConfig.Configs _ Where p.Description = "FROD" _ Select p.dateValue Dim qfreshc = From p In dbConfig.Configs _ Where p.Description = "FRCD" _ Select p.dateValue
Then comparing these date values to the current date: [Code] ..... But for some reason its always returning the Else condition - even though the values in the database should make the query true. I'm guessing for some reason its not pulling the results as a date?
My brain may just be fried since it's the end of the semester, but my teacher kicked this back to fix and resubmit...she said that I am "returning the name of your function rather than your variable name".
Here is my code for all 3 forms.

These are forms to calculate the cost of getting a cell phone package.
returning a function value? I have a simple function that returns an integer. This function works fine when executed in SQL Developer but, when called from my apps, it always returns 2 regardless of anything. I have checked it over and over again, I cant seems to find where I am going wrong.

My VB code uses a timer with a slider, and uses AddSeconds. I am trying to use the slider with a min value of 0 and max value of 600, and set up ticks every 30 seconds between 0 and 600.At a beginner level coding VB,I am not sure how to set some of the correct values in the slider's property box.Min, Max and Value, I am guessing are 0, 600 and 0 (sets the slider thumb starting positionat the far left). But I am not sure what other values, like tick and small and large change, etc. need to be set and set to what value? I've read online, but so far cannot find how to configure this.
Public Function Checked() As Boolean Return applyChange 'this is a string! End Function
Whats going on here? How can a function with return type Boolean actually return a string? I'm assuming theres some implicit conversion going on here, which I'd rather not have.
I am hopeing someone can help me here with a recursive function I have that is not returning either true or false as I would have espected it to. The function loops through a Active Directory group for its members and then calls itself if it encounters any groups within the membership in order to gets its members as well. I am trying to return either true or false based on if any errors were encountered but not haveing any luck at all. It appears to just hang and never return back to the primary calling sub that starts the recursive function. Below is my code I am using:
If an object is created inside a function and the function returns that type of oject how is the memory handled.
Example:
Public Function GetEmployee(employeeid as integer) as employee Dim oEmployee as new employee oEmployee.FirstName="Bob"
[code]....
Does the variable that receive the object still a pointer to the memory location that was used inside the function?What about when you do a oEmployee2=oEmployee.Is oEmployee2 just a pointer? And any changes to oEmployee will now affect the other. Just trying to understand it from a memory perspective and how that scope works?
I have stored procedure which I will execute its result and pass it into a Dataset and return it but at the same time I have a Output parameter in my stored procedure which I also want to return, how can I return both the dataset and the integer output value with my function, or is there a more 'appropriate way' to handle such situation?[code]
I need to return an array but the array size will change from one call of the function to another so I need away to storing the returned array. The function is as below, and as you can see the returned array will be of different sizes:
Im overiding getRolesForUser() I have 2 columns i return from the query IAdapter.GetRolesByUserName(userName) returns two columns (roleID, formID) How can I return them and access the two columns data? 2 dimensional array?

I'm making this game where there is an enemy that goes to the center of the form and grabs an object and brings it back to the side. I made a new class called enemy that makes the enemy. in the class there is a sub called start which the enemy goes to the center and brings the object back. when the enemy comes back with the object i want the integer lives to subtract 1 from it. so i put the
If Not Rect.IntersectsWith(Form1.ClientRectangle) Then Form1.Lives -= 1 End If
where Rect is the enemy's bounds. when ever rect is not intersecting with the forms bounds (which means when its off screen) lives should subtract 1, but it doesnt.
The code underneath works when I use WM_MOUSEMOVE but not when I use WM_NCMOUSEMOVE. Is WM_NCMOUSEMOVE not supported anymore?I use the correct values for the constants too.Protected Overrides Sub WndProc(ByRef m As Message)Dim MousePosition As Point
Select Case m.Msg Case WM_NCMOUSEMOVE MousePosition = New Point(m.LParam.ToInt32()) If MousePosition.Y < 50 Then CloseButtonState = ButtonState.Flat Else CloseButtonState = ButtonState.Normal
