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

View 4 RepliesForms :: Can Make Variable Actually Seen As A Variable?
Feb 17, 2011I have a VBA form in Microstation I am using to try and help automate a task. The only problem I am having is I am reading a textbox (Filebox.Text) and setting it as the variable (FN). It works, because I used Msg.Box (FN) to test it. However, in two of the lines of code, I am trying to use (FN) to pass the typed in filename to the command to run in Microstation. Unfortunently, it gets passed on as (FN).dgn instead of the actual filenale typed into the textbox. Is there a way I can make the variable actually seen as a variable? Code on Pastebin: url....Also, not sure if this is the right section, 100% new to VBA, coming from a world Bashed together.

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.
C# - 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?

View 1 RepliesForms :: Can't Pass Variable From One Form To Another?
Jun 8, 2011I have one form, which the user enters upto 5 websites then clicks go - I have on the second form, the one with the webbrowser. A timer which checks if the web browser is busy then either a green light or black image will be shown along side the assocaited input box on the first form.I am finding it impossible to feed variables into the clock through ByVal, like I would a subroutine or function.
Private Sub ActiveMe_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ActiveMe.Tick
If ((WebBrowser1.IsBusy)) Then
Hey.BackColor = Color.Black[code]....
'Error message says Hey is not declared, as i can't pass it through to timer
The variable Hey is determined by the first form - Which picturebox.I have an if statement which simply says if inputbox one has url enter then Hey = Picturebox1, If input box2 has url entered then Hey= Picturebox2 etc.What I want is the timer to check the page has completed loading or is still loading or refresing and the appropriate green or black to be shown aside url input box on first form.I considered using a sub or procedure to act as a clock (a large for loop with another for loop within it, acting as a delay). But found this slowed down theapp to the point of crashing it.
