I have a sub (Sub 1)that passes a control to another sub (Sub2) Sub2 only knows that the control will either be a picturebox ("Pict1") or a rich textbox ("Rchtxbx").I want to put code in Sub2 that does the following if the control that is passed is aPictureBox:ictureBox1.Load("C est.bmp")However I don't know how to do this as when I type in "x" in Sub2, it does not default to the PictureBox properties and methods.Is it possible to use the name of a control and wrap it in some sort of ControlType() enclosure that identifies its type and grants access to its properties and methods?
I am trying to figure out the best approach for setting and getting properties in a nested class I am creating. I have a class, Car which has a nested class ControlPanel and want to make the properties of the Control Panel only accessible to the Car and Control Panel class.
I've created a class library and built a dll (release build). I've then referenced the DLL in another project (I've tried several). I can see the namespace and classes in Object Browser and I can declare instances of the classes but I cannot use or see any of the methods or properties! there is no IntelliSense whatsoever and calling the methods manualy results in a 'Declaration expected' error.
Within the class library solution I have a unit test project referencing the class library project which works all works fine (and all the tests pass).
Can anyone provide any pointers to what might be going wrong here? I've built plenty of dlls in the past and have had no trouble referencing them at all.[code]...
I am trying to dynamically create COM object, call COM method and set COM properties. The COM class is a VB6 ActiveX DLL. The implementation is exactly equal to the VB6 code from this page
I have a class definition that I've seen other define properties that return collections of objects.
Public Property GetAllAdults() as Adults End Property I made the argument that this should be a method in the class, because it doesn't define an attribute of the class, and could not be extended with parameters. Is/Are there reasons why this should be defined as a property vs. a function?
Is it possible to iterate through the properties and methods of a custom class, getting the details about those properties and methods in the process.[code]....
I have one text box that the user enters an integer into. I use a select case to determine what the length of the number is. (along w/ string.length, etc)based on how long it is, I can determine if the number is 1-9, 10-99, 100-999, etc. What I want to do next is, evaluate the number and display a roman numeral that matches.
intMyNumber.substring(1,?) ' 1 would return the leftmost number if intMyNumber.substring(1,?) = 1 then if intMyNumber.substring(2,?) = 1 then 'etc
I came across a DbParameterCollection object, which should have an "Item" property inherited from IList, but IntelliSense does not show this object has the Item property.
Is there a simple way in vb.net to mask a public property or method from the internal namespace? It would be helpful as a refactoring tool to isolate internal dependencies and perhaps to enforce a non-recursion policy for external services.
When you type sender. IntelliSense lists 5 methods and yet if you type sender.Left or sender.top these will work. Why don't these properties show up as available for use via IntelliSense.
at some points, I need to call the same method on those controls (ex. user presses the clear button on the big control, I want to call the clear f(x) on each of the controls)I thought to toss the controls in a collection, and then be able to handle them something like this: nextturns out, and I should have realized, methods and properties of controls are not exposed when treated this way. The only thing that can be seen is the stuff that the base class (control, I guess) has.
limit the default events, properties and methods exposed from a UserControl so it only displays to the developer the new events etc that I code myself.What i mean is I have created a UserControl with a panel and 5 buttons, written 1 Public Eventonly at this stage, I have placed an instance of the control on a form in a new project, but in the drop down menu that comes up after say (myUserControl1.), there is a massive list of options, I don't want those to appear.
I am writing my first class-library in VB.NET. My idea is to distribute this library so others may use it in their applications.However, perhaps due to my lack of experience in writing and structuring the library and the classes therein, I noted that the methods/properties are ALL being shown in the IntelliSense of Visual Studio.
The thing is that many of them are only used within the library itself and should NOT be used by the developers (could create a disaster) when they incorporate my library in their application - only a few should be visibile i.e. the ones which are needed by the developer.Thus, my question is: is there a way to hide certain methods/properties of my library from Visual Studio's IntelliSense? Maybe something similar to REM?
EDIT: as mentioned - this is my first library and I now understand that my question could be intepreted in two ways:
1) how to hide something from IntelliSense
2) how to prevent a developer from using and calling certain methods/properties
Of course, the end-result that I want is that the developer is not able to access AT ALL certain methods/properties i.e. No. 2 above.
I want to know what are classes , objects , a namespace , subroutines,functions,methods,properties and differemce betweem byval and byref in your words.
Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.
' File Definitions.vb
Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)
Public Class MessageEventArgs : Inherits EventArgs Public Message As String

The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.
I have troubles with processing callback method invoked from a C++ DLL. Imagine: there is a ListBox on a Form; I wish to fill it with Items from callback. In Debug mode, I got a System.InvalidOperationException, because I access ListBox methods from different thread
What faster methods are available for VB to access the internet? I.e. methods which are faster than simply using VB Browser, as people make web bots which access multiple sites quickly which I would imagine meant there is a faster way.

If I have an application that load some assembly at runtime. Is it possible to access the events and the methods of these assemblies direcly, without always using Reflection
There is a site that I go to that has a website chat thats located at the bottom of every page. It allows you to talk to specific people while you're online and they're online.
Sometimes when I get into a good conversation I don't want to end it. I still have other things to do though.I wanted to make a small window that I can just drag around that will allow me to chat with people easier.
I've set up pretty much everything in this program except the actual retrieving of the information from the site and the replying to the chat. I know I could do this (I've done similar things in the past) by putting an invisible webbrowser object off to the side and just run my stuff through there. But I think thats kind of sloppy.
I've read in some of my classes and books and have learned how to make simple web requests that return the results. In its case, I had to return definitions from google. I tried this on a recent project but found that it didn't the permission to access any kind of secured account whether it was logged in or not because it was "unsafe".
Does anybody know how to access a page thats been logged into through IE but without needing the sloppy methods I mentioned earlier?
I have a class which has various methods that I need to make public to only 1 other class. Is this possible? I don't want to make them public for everybody, just that 1 class.

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'm just getting started with Visual Studio (2005), and my aim is to write a fairly simple application in Visual Basic that will need to store some data to disk.What I really want is to be able to send the application to the end users (xp, vista, win7) and have them just be able to use it without having down download all kinds of extras. For example I'm guessing that if I use an SQL database in my application they will need to download SQl server express or some other sql downloadable?
If so is there a similar downloadable for MS Access?I'm just in the 'seeing how things work' stage at the moment and I don't want to waste time going down the SQL track just to find it won't actually work unless my users all download SQL to their machines (which they won't want to do).
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()
