So I created this thread: Invoking Private / Protected Methods Via Reflection From The Same Object Instance (or Base) And we got the problem fixed save for private methods. As this may not be the same issue I thought it may be best to post a different question with the full source. It is still a work in progress but it is functional.

So this class is being inherited by a (so far) empty child class and ProcessStage is being called. Notice that ConfirmFormDataIsValid() sub is private. If you run this it will not find this method. If I change it to protected however it works fine.
I'm new to C#.Till this moment I used to make every global variable - public static.All my methods are public static so I can access them from other classes. I read on SO that the less public static methods I have,the better.So I rewrote my applications by putting all the code in one class - the form class.Now all my methods are private and there's no static method.
My question: What should I do,keeping everything in the form class is dump in my opinion. When should I use public,when private and when static private/public? I get the public methods as a 'cons' ,because they can be decompiled,but I doubt that.My public methods can be decompiled too.What is so 'private' in a private method? EDIT: I'm not asking how to prevent my program to be decompiled,I'm asking whether I should use static,private and public.And also : Is there are problem in putting all the code in the form class so I dont have to use public methods?
I have a form (frmMain) that contains a custom control (con class). frmMain contains a combo box control and when the user selects a value from it, I pass this value to a sub routine within con class (see red line below). This purpose of the sub routine is to populate a set of comboxes contained in con class according to the value that is passed in.
Private Sub cboGuidelines_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboGuidelines.SelectedIndexChanged If bChanged = True Then
I want to retrieve private (implementation and other) methods of a class which implements an interface and also is derived from (inherits) a base class.How can I achieve this using reflection?This is wat m tryin to do. I need to view these private methods and their contents, I don't want to invoke them.
Dim assembly As System.Reflection.Assembly Dim assemblyName As String assemblyName = System.IO.Path.GetFullPath("xyz.dll") assembly = System.Reflection.Assembly.LoadFile(assemblyName) assembly.GetType("myClass").Getmethods(Bindings.NonPublic) assembly.GetType("myClass").GetMethods(BindingFlags.NonPublic) isn't working
Which always calls a method with no params or return. The idea is that the user of my object (transactional processing of business logic) inherits the base class adds in a load of private methods to fire. They then add these method names to a list in the order they would like them fired and the code above will take care of firing them.
It works fine with public methods but not with private or protected methods in the same class (Protected because I have some 'standard' pre built methods to add to the base class). Realistically I could make the methods public and be done with it but my inner nerd wont allow me to do so...
I am assuming this is a security feature. Is there a way to get around this or does anyone have any suggestions on how to proceed but keep my tasty, tasty visibility modifiers in tact?
(NOTE: ITS IN VB.NET but a C# Answer is fine if that is what you are comfortable with).
It works, when I make getBar methods public, but I don't want to expose these unneccessarily. Why I can't call private shared methods from a public one in the same class is over my head. I'm using .net framework 4.0 in a web application.
if for example i have two private sub I declared a local variable on private sub a... is there a way that private sub b could use the variable created on private sub a? Im asking because im in a problem in my app were using global variable is not an option to make the long story short

Does anyone has an idea what i should change to let it work and let my UserRepository use the methods in RepositoryBase while implementing the IUserRepository?
I am working with a vb program, but there is something strange on one of my .vb code pagewhen i put the "dot" afther the object name its dont show the methods availables for this objectbut on other vb code pages i can see it. but in this one no.for exmaplethis is a piece of code: Dim sb As New StringBuilder()
I am not sure how clear my question is by the title, but I am trying to make Class methods instead of Instance methods in Visual Basic that way I don't have to waste memory and code creating temporary objects to execute methods that don't need instance variables.
I am not sure if you can do that in VB but I know you can in Objective-C by using either a "+" or "-" sign in front of the method declaration. And in C++ (at least I think, I can't remember) you put the static keyword or const keyword in front of the function.How would I do this in VB if it is possible? Or should I just make a separate set of functions that are not members of a class?
reflect a set of data in xml using the above mentioned tools.i was thinking that the xml should be converted to a dataset first. however, i couldn't see any useful sites.
I have to create a SQL server DB that has a table named people with, people_id int PK IDENTITY, firstName varChar(30), lastName varChar(40 (completed) create a windows program that lists the firstName and lastName combined with a space detween them in a listBox (completed)provide functionality in code using command objects/parameters (no wizards) to add and delete from database and reflect the changes in the listBox..I am having trouble with the delete. [code]
I am in a situation where I have a tool which is always running. Now if any new entry is added or deleted from the database then unless we dont restart the application it will not reflect the changes. So I want that the application itself should check for the updates or at least it should refresh itself.
For some reason my tab pages won't update their data when I change the data contained in them. I have to scroll to the next Company and then scroll back for the changes to be reflected in that particular tab. I have no clue why this is as when I walk through my code in debugging, it shows that the appropriate labels are being set the appropriate values. But if I have one of the tabs as the one in focus when I change my company, it is updated correctly.
I need to let a textbox.text value to have the same text as the DatetimePicker.Text value (as formatted)The Text value in the datetimePicker control shows the correct formatted date, however the the texbox remains blank.[code]
How to I reflect back the name of a type that is supplied as a generic parameter? I would really like to know how this is done in both C# and VB.NET. See the following example code and expected response.
In C#:
public void Test<T>() { Console.WriteLine("The supplied type is {0}",???) }
[code]....
Executing Test<String>() or Test(Of String)() should produce:
I am currently developing an application that is linked to a MS SQL Server 2008 Database. So now I realised that I needed to make a few minor changes to the database (add new columns to some tables, change the data type of a few columsn in some tables). After making the changes, I realised that these changes have not been updated in my VB application's dataset. I then tried to "refresh" the dataset, but it still is not updating the dataset. What do I need to do to update the dataset to reflect the changes in the database?
Something that has been confusing me for a while now with WPF MVVM is for example, when I have a base model containing nothing but a few properties and some validation code and I then build a view model around this base model, how should the view model be structured.
For Example:
Base Model -> Imports ModellingHelper Imports FTNHelper
[Code]....
What I am wondering is, if there is a better way to structure the view model to improve data binding, so I don't have to bind to Source.Name etc. How should I handle the base model in the view model?
I have linked VB to my sql server and all my tables and data load correctly in VB.I drag and dropped my table in "detail" view and then debugged the program, little did I know, when I tried to add a new instance of data into my table I literally have to enter the primary key. I am trying to figure out how to set the "STU_ID" (PrimaryKey) to auto-increment off of the last row of data on my table.
I'm quite new to this app.config function. Hope someone can show me the road on this. I have a solution which comprise of 5 projects and one of them just to retrieve the value from the app.config file to be read by other projects. So, in the app.config file, i have my connection string stated inside and i can use it nicely.
i have a sql database, and have created a dataset for a sample table in it.The dataset is HotelDataSet2 and data table adapter to insert to it is Various_itemsTableAdapter.
This always reflects the same count, before and after inserting..But if i execute this
[Code]...
it shows the new count to be +1 of the old one. So i concluded that everytime i change some data to the table via table adapter, i have to always refill the dataset?? How is that useful then??
I have a form with an Adobe PDF reader control. I point to a specific PDF I want to load when a button is clicked. The PDF is 28 Megs big and takes some time to load into the reader. I would like a progress bar to to show (like a showdialog kind of thing) so the user does not click all over the place and thinks the app is static.
The PDF reader is loaded like this: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Me.AxAcroPDF1.LoadFile("c:Section3.pdf") End Sub
How would I update the progressbar1 control to reflect the time it takes to load? I checked the AxAcroPDFLib Namespace and found no "progresschange" type of functions or events.
I am doing project in vb.net using ms access I used listview to display data from table I want to display different context menu strip for different column I have done it using hard logic to get column number is as follows:
Private Function getClickedColumn(ByVal pListView As ListView, ByVal pMouseX As Integer) As Integer Dim result As Integer = 0
[Code].....
Also i want to edit any cell of the listview & update its result to database .
I have an object databound to a WinForm. One property, BOLNumber is bound to a textbox on the form. When you change the value in the form, the underlying BOLNumber property is changed. But the property setter does some "formatting" to the value. I want to BOLNumber textbox to reflect the changes to the value made in the property setter immediately upon the textbox losing focus. I tried implementing the INotifyPropertyChanged interface, but I am either doing something wrong or misunderstanding something it would seem. How do I get the databound control to reflect the changes to the underlying data source?
Public Event PropertyChanged As PropertyChangedEventHandler _ Implements INotifyPropertyChanged.PropertyChanged Public Property BOLNumber As String
