After Inheritance Of Form A Listbox Is Not Accessible Due To May Be Its Protection Level
Apr 19, 2012I've got a form with a listbox on it.In a second form I inherit the complete first form. But when I try to use that listbox in the second form with e.g.Index = LstWoodshop.FindString (Order(0))(where LstWoodshop is that inherited Listbox) I get the error message:'LstWood shop' is not declared. It may be inaccessible due to its protection level.What or where can I change this setting so that this listbox on form 1 is also available/accessible on form 2?

Make A Variable Accessible To Any Module?
Dec 30, 2009I have an issue with an app i am writing, i need to make a variable accessible to any module or class within the project but that cant be accessed outside of the app as it is accessing info the end user shouldn't have access to.
Ok, well a practice i have gotten into in the last few years is to declare a module on the same page as the main form and declare variables either friend or public (global variables). with my app public is not good so i tried Protected Friend but i cant use this within a module.
I tried placing it at the top of the main form but one of my classes can't access it, what would be the right way to do as expected. besides the main form i have 2 classes call them class1 and class2:- main interacts with both classes class1 accesses class2 class2 doesn't access class1

Make An Array Created & Filled In By One Sub Accessible From Another One?
Nov 28, 2009I have a RadioButtonList control which triggers a Sub LegalGaps on SelectedItemChanged event. This Sub creates and fills in an array the size of which depends on the User's choice of radiobutton options. The second Sub AvailableDays shall be able to read that array and highlight the days in the Calendar control accordingly on DayRender event. May I somehow declare an internally created variable a public one?

Way To Make A Value Accessible Only To Parent Of A Nested Class
Jun 24, 2009In general, according to the OOP paradigm, my understanding of encapsulation basically says:
-If a member is private, it can only be accessed by the class.
-If a member is protected, it can only be accessed by the base class and any derived classes.
-If a member is public, it can be accessed by anyone.
If I have a nested class, can I declare a property to be accessible only to that class and the parent class it's nested within? For example:[code]In the example, I cannot directly access myNestedObject.myInt or myNestedObject.myDbl from an instance of ContainerClass if those members are Private or Protected. But suppose I don't want to make them Public,because then they are TOO exposed: they can be altered from anywhere, not just within a Container Class object. Declaring them Friend would still be too weak as that would allow them to be altered from anywhere within the application.
Create An IMAGELIST In A Main Form And Add To It Then Have It Accessible Within A Child Form?
Mar 22, 2011I want to create an IMAGELIST in a main form and add to it then have it accessible within a child form. I found several MS examples on database shared access but this is NOT the concept I am after. Straight forward:
Child_Form.<function_to_execute_in_child_form>(The_Passed_Imagelist)
So, within the child form it want to do whatever I like to the IMAGELIST! I have tried passing the object by reference and anything I could think of.
Object Passed ByRef To Form, But Not Accessible Throughout Form Class
Feb 18, 2010Hi
I've got a pretty general question about the best practice in passing an object reference to a Form in VB.NET. My form is a dialog and I've created an overload ShowDialog method, where I pass an Object into it ByRef.
The trouble is, I want to be able to refer to that Object throughout my dialog Class and not just in the ShowDialog method. For instance, some of my Events for controls on the form, need to reference that object.
I know I could create a local Private variable in the Class and assign it to the passed value, and then use that value. However I'm thinking this isn't very efficient because it would (I believe) create a new copy of the Object (which is a complex, large class in itself).
Make Form That Contains A Button And A Listbox?

Student Name G1 G2 G3 G4 G5 AVG GRADE

ListBox PreferredHeight - Make ListBox Calculate Correct Integral Height Before ListBox Is Made Visible
Nov 19, 2009If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False

View 3 RepliesC# - Make An Object Accessible To Only One Other Object In The Same Assembly?
Sep 15, 2009Each business object has a matching object that contains sql calls. I'd like to restrict these sql objects in a way where they can only be used by the matching business object. How can this be achieved?
Update Greg brought up the point about testability. Since the SqlObjects will contain very business-process specific sql I don't want them reused in multiple buiness objects. (Basic CRUD operations are all code-generated) Is there a way to make the SqlObjects accessible to only one business object in the business assembly (like yshuditelu and Greg Beech showed) AND expose the SqlObjects to the unit testing assembly?

Jul 27, 2010I have a class library written in .Net that I would like to make available to VB6/VBA. What I tried did not work (obviously as I am asking this question). Here is what I did:
I Created a Class Library Project in Visual Studio 2010 Express and put the code in a Class Module.I opened the project properties and went to "Assembly Information" and checked "Make COM Visible". I went to "Advanced Compile" options and targeted .Net 2.0 (it's very simple code).I then removed all references expect for "System".I built the project (no warnings or errors) and copied the DLL out of the Bin folder into C:WindowsSystem32 I ran RegSvr32 to register the DLL and got the error: The module "MyDll.dll" was loaded but the entry-point DLLRegisterServer was not found. Make sure that "MyDll.dll is a valid DLL or OCX file and then try again.

Make A Listbox Look More Appealing?
Jan 6, 2010I would like to display over 20 items in a listbox under about 10 headings. As you can imagine, with the varying lengths of each cell, this looks pretty messy. For example, if a name is long, it takes both the space under the name heading and the number heading.
How can I avoid that while still use listboxes, and NOT DataGridview! I'm having an awful amount of trouble with Grids!! I would like something simple yet neat.. Can't I have columns or dividers in listboxes?
