Forms :: Access Variable Of Child Form?
Jan 3, 2012I have about 60 Child forms
Each have a variable with same name.
In Main form I want to set the value of the variable of the active child.
One way of doing that is like
Select Case Me.ActiveMdiChild.Name
Case "formName"
frmformName.Variable=0
I donot want to do that as it involves writing many cases and I may miss some.
Is there some other way of doing it .
I tried
Dim O as Object = Me.ActiveMdiChil
O.VariableName= 0
and its various variants but its not working
Sharing Parent Variable With Child Objects?
Nov 5, 2010I am developing a new class which is a control that inherits from the "Panel" class. In this new class, I have three objects that are generated every time I create a new instance of the class. For simplicity, I will call this class "garage" and the three objects "BMW," "Lexus," and "Acura." So each new garage has three types of cars.
how can I share a variable from the Parent class with all of it's child objects? i.e. The garage has an array variable called "tires" which all three cars use. Rather than create each car object with the tires parameter, I would just like to keep the tires parameter in the parent class so that all my child objects can use it. I know that normally the parent class should provide the child class with all information when creating the child but it would seem redundant to pass the entire tires array each time since all three cars use the same tires and the tires object never change.

Syntax Checker - Populating My Combo Box With All Of A Root-child's Child Element's Names?
Mar 10, 2009My program handles XML files that have certain elements within a root-child node that are identical expect for their inner text value. So while populating my combo box with all of a root-child's child element's names I get like five identical items listed. Which brought about the problem of selecting say the third item and getting the value of the first displayed. So I came up with a loop function that determines if the selected combo box item is preceded by one of the same name, if it is, then it adds +1 to a counter variable and keeps checking farther and farther up the list. Once it loops to an item that doesn't have the same name it exits and it reads the Xth (X = counter mentioned earlier) element's inner text from the file. This works great for elements 1, 3, 4, and 5. But not for 2. A while back when I was focused on this problem I discovered the root of the problem but I was unable to circumvent it. I'll put the loop below so you can see the problem in action instead of trying to follow my verbose explanation:

Filter Parent / Child Table In Linq Query Based On Entities In Child Table?
Jul 9, 2010I have a table (Projects) which is linked to projectVersions on projectID..projectVersions contains several columns on which I'd like to filter a returned project (and associated projectVersions) list. For example there is a "capacity" column and a "country" column. I am doing a filtered list of projects on one page and I'd like to include all projects where any one of the associated projectVersions has a capacity of 750ml and a country of "France" for example.It may be that a particular parameter is not set and so I pass a zero to indicate not to filter on that.I guess this needs some kind of subquery as when I try and do something like this: [code] it doesn't work as the "xxx" bit, being one-to-many, expects me to specify an item to get at the entities within and yet I want to query where ANY of the associated versions match one of the criteria.

MDI Child Maximized - The Child Form Shows Maximized In The MDI Parent But Behind The UserControl
Nov 12, 2010Note: I am working with Visual Studio 2010 Professional. Note: There are a lot of MDI Child posts, but none (that I have found) that apply to my scenario... Scenario I have an MDI form with a UserControl docked at the top. The UserControl is for navigation and is ~50 pixels in height. When I show a child form with its WindowState property already set to 'Maximized', the child form shows maximized in the MDI parent, but behind the UserControl.

View 2 RepliesVS 2008 MDI And Child Within A Child?
Feb 13, 2010I have an MDI application where a child form (A) opens a second form as a Dialog (B), which works great but you can't do anything in the MDI until you close the Dialog form.I've now changed the Dialog form (B) so it just calls as a Show and I have disabled the parent form (A). This works better and allows you to click anywhere in the MDI (except the parent form (A)) which is ideal and works much better.
The problem comes if you maximize the parent form (A) and then open form (B), this is then also maximised but I need it to be a fixed.I've done some research and I've tried using the API SetParent which gets round the problem of the form being maximized but this makes the form TopMost in the MDI.
All I need is form B to be topmost of form A and to be a fixed size. Is there any solution?
Program Function - Says, "The Type For Variable [variable] Will Not Be Inferred Because It Is Bound To A Field
May 18, 2012Public Class Form1
Dim x, c, number(0 To 19) As Integer
Dim s As Integer
[CODE]...
The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.
-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop. Button1 ends the program, Button2 generates the list one time only, Button3 is supposed to loop the generation of the list, and Button4 is supposed to end the loop, but not the program.
VS 2010 Compiler Creates New Variable Automatically When Use If Statement Without Strictly Declared Variable?
Jan 10, 2011Say that i have the following code that parse about 20k records from the DB.
Code #1
vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While
And then another code which does the very same thing but it seems to be a little cleaner.
Code #2
vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While
This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?
Variable Naming Conventions To Illustrate Variable Type And Where Variables Are Declared
Aug 24, 2009I am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.

Object Variable Or With Block Variable Not Set - From Property Get With Bindingsource.current?
May 31, 2012Now I have the need to get a current value from a bindingsource in a property of a user control.In a previous thread I had tracked down the "Object variable or With block variable not set" to the return in the Get block of a property. At the time I was only using the Set so I just commented out the offending code until I needed it.
[Code]...
The error does not occur during a system compile, only upon saving the container object of the user control. As I said the Set works correctly, only the Get causes the error.I would like to know what I am missing/misunderstanding and am open to other suggestions of handling retrieving the current value of a bindingsource in a user control.
