"Method Not Implemented" - Curve Clear?
Jul 17, 2010
I have two forms, a main display form with a Zedgraph Pane on it and a second form with a single ComboBox control, opened by a button click on the first form and having its ComboBox filled by the Labels of the curves currently being shown by the Zedgraph pane.The code below seeks to remove the curve selected in the ComboBox by clearing its points, but on the CurveList.Clear line, I always get a "Method not Implemented" error.
Private Sub rmvCurve(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chnlSelectRmv.SelectedIndexChanged
Dim curLabel As String

I am programming an ordering site in VB.Net and ASP.Net.I start with the main ordering form and the idea is that the user will select a subject from the drop down list and then click a button to retrieve all modules associated with that subject in a second form (smaller than the main order form).I have created the second form (frm2) and added content to it.In the main form inside the method which represents the button being clicked, I have coded the following:
Dim frm As New frm2()
frm.show()
I then get an error that show has not been declared and so I create a method stub for it.I run the program and when I click on the button I get the following error:'method or operation is not implemented.'This points to the following line in the 2nd form:
Sub show()
Throw New NotImplementedException
End Sub
what I need to put inside this method to make my second form load when the button is clicked?

I'm seeing a strange build bug a lot. Sometimes after typing some code we receive the following build error.
Class 'clsX' must implement 'Event PropertyChanged(sender As Object, e As PropertyChangedEventArgs)' for interface System.ComponentModel.INotifyPropertyChanged'.
And
'PropertyChanged' cannot implement 'PropertyChanged' because there is no matching event on interface 'System.ComponentModel.INotifyPropertyChanged'.
Those error should never go together! Usually we can just ignore the exception and build the solution but often enough this bug stops our build. (this happens a lot using Edit and Continue which is annoying)Removing the PropertyChanged event and retyping the same code! sometimes fixes this.We're using a code generator that causes this error to surface but just editing some files manually triggers this exception too. This error occur's on multiple machines using various setups.

I am new to Visual Basic 2008 and NET and am using the Visual Studio 2008 Express editions. I recently downloaded the ebook "Build a Program Now!" for VB and have been working through it without problem until te end of the penultimate chapter 8.
Part of the exercise includes the following code:
Private Sub tsbFilterByMake_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tsbFilterByMake.Click
Dim filteredByMake = From Listing In Me.CarTrackerDataSet.Listing _
[CODE].........
Whenever I attempt to execute this code, I get the error "The method or operation is not implemented" on the last line before the End Sub. This suprised me because when I typed in the f after the = sign, Intellisense offered me the single choice of the required filteredByMake, suggesting to me (in my probable naivety) that it recognised it as a syntactically corrrect choice. This is not down to an error on my part somewhere in attempting the exercise as I get the same result trying to run the Complete code solution that accompanies the book. I have successfully replaced this and a similar Sub with SQL queries on the datasets in question, why the above code does not work and what can be done to correct it.

I think I've misused this method and would like to know what it actually does.I 've looked it up on msdn forum and found this
[code...]
What does it mean by removing all the rows in all tables? Is it the datagridview table? When it says "removing", does it mean that it deletes everything?
The reason I misused it is because I thought dataset.clear means it flushes the record held in dataset.
When I click on the add new icon on bindingnavigator, a new form will appear, which allows me to insert data
[code...]
when I close the insert form, the parent form will be activated and datagridview will display the new record I just inserted. I thought the dataset.clear method helped display the new added record but then I realised I could do without the dataset.clear method.

I have a large set of latitude and longitude coordinates from a GPS which, when plotted, creates a 'jerky' line over time. I would like to 'smooth' this line into another set of coordinates which I can then plot to make the track more 'smooth'.
I may need to add more intermediate coordinates to do this. I just wondered if there are any code snippets out there or even MS Excel functions

I found the line in a program that references UrlNormalizerUtil.UrlNormalizer to validate a url. It calls it from a GeneralPurposeUtilities file which is added to the project properties in references as a .dll file.
My question is: where does this file come from? Is is self coded or from some library? how else can the UrlNormalizer be implemented?

I'm working in .net 2005. I have a collection of points and I'm creating a polyline with them; however, I need to curve fit them so that they appear to be some what straighter.
If you look at my picture, you can see the blue dots represent the points and the red line is a represenation of how I'd like the final results to be. (Basically, I need to line to appear straighter and less jaggedy looking than it is now).
I didn't know if I should try to see if there's some plug-in for doing this or if vb.net has anything I could use to do this myself.

Write a program to analyze a list of grades to determine the number of A's, B's, C's, etc. after applying a curve percentage selected by the user. When the form loads it should contain all the grades and available curves in the list boxes on the left. The user selects a curve and clicks the "Apply Curve" button. The program should display the curved grades (based upon the selected curve) and the grade distribution in the list boxes on the right?

How hard would it be to graph a curve of a function in a VB form.
Attached is a graph from excel which is exactly what I need to do.
I have the function of some fluid properties and I'd like to choose a min and max temp then have the function graphed, with temp as the x and the fluid property as the y which would auto scale to fit the curve.
Actually now the program i have to return the properties at one temp is just a GUI front end to call a fortran program to return the properties so actually if I just use that it'd be graphing points and not directly from the function. I can always make it completely VB based if graphing from a function is easier than points. It'd be a slight pain to rewrite all the code for the functions though.
