How To Access Controls' Private Properties On Another Form
Feb 25, 2010
I am trying to access the controls' properties on another form without having to modify the code of the other projec (the one containing the controls that I want to access) because it is already compiled as a DLL. In this DLL that I am trying to access, the functions/sub-procedures are all declared as private. Would there be any way of accessing the controls' properties without having to modify the DLL? Basically what I am trying to do is create a sort of console application wrapper for the DLL that would create a new instance of the DLL's form and then make certain checkboxes checked and click certain buttons. Basically, I am trying to automate the form as it currently exists.

Below is the class with a property.

{
public int MyProperty { get; private set; }

What's the benefit of typing private access modifier in setter ?

After taking a few years off from programming, I decided to start learning vb.net. I have created a user control that contains a picture box. I added some custom properties to the picture box that will hold general string data from a database.
My problem is that the user control is programatically created during run time, and during this time a DoubleClick event handler is added for the picture box that is within the user control.
I need to be able to set the custom properties for the picture box during the creation of the user control, so that when the control (picture box) is double clicked I can read these values but am unsure on how to access them.
The picture box is the entire size of the user control, or I would just add the custom properties right to the user control and add the DoubleClick event handler to that. However, double clicking needs to be done on the picture box since it takes up the entire user control, unless anyone has an idea to trigger the DoubleClick event of the user control when the picture box is double clicked.

How to access a variable that is located in a private sub and then display that variable in another private sub located on the same form.
My actual code is:
Public Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
Dim strFileName As String
strFileName = OpenFD.FileName
OpenFD.InitialDirectory = _
[Code] .....
Obviously, the sub in blue has nothing in it currently and so this is the one I would like to access the variable in. The variable I want to use again is 'FILE_NAME'.

I'm trying to write a routine which will produce a list of the values of some of the properties for every control that I've placed on a form. I can do this manually by looking up the names of each of the controls, but I'd rather use a construct like this -for each formname as string in xxxx
for each ctrlname as string in yyyy(formname)
....
next
next
However, I'm having problems with the various examples of this code that I found in the library. I'm not sure whether it's because I don't know how to set up the syntax correctly or this sort of construct isn't possible in this context.

I am running Visual Basic 2008 express edition. My controls toolbox is empty. There are also no properties for the form controls on my project. Just blank. I have removed the .net framework v2.0. I had the .net framework v3.5 installed at the time, and thought I didn't need the older version (v2.0). Do I need v.2.0 for the tools? If so, where can I get a copy? What's the filename called?

I come from C# (use VS 2005, .NET 2) and I know that when I declare a private variable I can "extract" from it the corresponding "property". In VB.NET I've declared a lot of properties (in the diagram class designer). Now am I forced manually adding the corresponding private fields?

I am programmer from some time only, I have certain doubts in fundamentals, could you please clarify on the following:Case 1:

Does case 1 and case 2 yield same result, I mean is a private value necessarily in there?, can we use property itself to use its own value in its Set and get statements?

I have a bunch of private variables I've typed out and I want to put all of my corresponding Public ReadOnly Properties in a bunch below them.Is there some way of copying ten lines of
Private _myVar As String
and pasting in ten sets of
Public Readonly Property MyVar As String
Get
Return _myVar[code]....
I'm currently copying the whole bunch of variable declarations, Find+Replacing Private _ into Public ReadOnly Property then going line-by-line expanding the definitions and writing return statements.how to avoid all this nonsense in the future, as I'm developing on a virtual terminal server, and the input lag on my little copy/paste/type operations on the code is driving me up the wall.

Is it possible to set a variable in my custom class for Private Read/Write access and Public Readonly access without creating Properties with Get and Set? In other words, from within my class I want full access and from my form I only want read access. Right now I declare my variable as either Private or Public to control Public read/write access. I tried googling my question a bit but I'm not sure what the correct terms even ar

I find that 98% of the time, any work I do with a Control on a From, I do within the form's class. Visual Studio automatically declares all of those controls as Friend, but there really isn't a need.Is there a way to have Visual Studio automatically declare all controls as Private and I can expose any controls as Friend as needed?

I have a form called form1 which has a thread that runs a sub from a module.[code]...
Well from the module, there's a part where I have to update controls on the form1. Whenever I try doing it, it updates the value, but not the design. For example I write a delegate which makes label1.text = "111", while debugging, label1.text becomes 111, but it does not show it updated on the form design, it just stays at its default value.

Trying to understand the best way to do this and I'm can't get it figured. Here's basically what I have:
Public Class CardParsingClass
Private iAcctIDStart as integer
Private iAcctIDLength as integer
[code]....
I've only included 2 of the class level fields here but there are actually 30, so that's why I was hoping to be able to send the name of the field to set and the value to set it at in the SetValue function. So in some other routine in the program I'd like to be able to issue the following call:
SetValue("iAcctIDStart", "3")
But then when I get into the SetValue routine, I'm not sure how to proceed. I thought about a case statement that would basically be this:
select Case strFieldToSet
case "iAcctIDStart"
iAcctIDStart = cint(strValue)
[code]....

I have an API that I created and currently utilize successfully in C#. I am trying to create an example of interacting with the API in VB.NET (so that the QA without C# experience can still utilize it for creating automated tests).
In C# I do the following
[TestingForm(FormName= "Land Lines", CaseType= _caseType
, Application= ApplicationNameCodes.WinRDECode, HasActions= true)]
public class LandLines : RDEMainForm
[Code]....
This gives me a compile time error because it claims that FORM_NAME and CASE_TYPE is not defined, even though the class has it defined inside.
How can I use the defined constants inside the class in the class attributes?

I'm using VS 2010 Professional built-in test cases. I've got a class that has a read-only property that looks something like this:
Private _server As IServer = Nothing
Public ReadOnly Property Server()
Get[code]......
In my test cases I want to make a fake server implementation so I can test some of the class methods without actually hitting the server. I've looked around and have seen the InternalsVisibleTo attribute, but that seems to only allow access to Friend-level members. Is there any simple way to get access to these members, aside from declaring them Public/Friend?
