Access A Button Through Code There Is On A Panel There Is A Child On Several Other Child-panels?
Aug 18, 2011
I'm from denmark and hope I can explain my question for you. This is just a example: I have a panel, let's say panel1 and another panel on that panel (panel2) and so on until for example panel5 - on panel5 I have a button (button1). Now I would like to change button1's backcolor property through code how do I then get access to button1, now it's a child-control on panel5 that is a child control on panel4 etc. ??

I have a regular form that I have a SplitContainer on and I would like to launch an external program (not mine) in Panel2, maximize it to fill the whole panel, and hide it's toolbar if possible. The program I am launching is a monitoring program of network activity. To be even more detailed, it is a puTTy window that opens a telnet connection to a server. I need to launch this putty window in Panel2, and then maximize it so that it cannot be resized/dragged.

So I'm adding a tab panel to a child window. A lot of our controls here are user defined but this looks like an ExtJS issue. When I add a tab panel, and then try and add controls and stuff to that panel, everything is cut off on that panel.
Here is the code I am using:
Using ViewDetailsWin As New Pages.ChildWindow
With ViewDetailsWin
.IconCls = Model.WorkflowStepDefinition.SmallIcon
.Ref = "viewDetailsWin"
[code].....
I can't even see the dropdown at all unless I scroll on the tiny little scroll bar it creates. It gives like a quarter inch on the screen to see anything inside the tab panel. There is no size property on the tab panel from what I can see.

I'm a bit confounded about how to proceed. I'm creating some kind of gameboard for a friend of mine. I have a splitpanel and the game grid will appear in the 1st panel. I put a panel with a 100x100 square in tile background format. called it gridpanel.i want that when I double click on gridpanel, a semi-transparant picture box frame (called Target) appears on your grid-square. I handled it like this :
Private Sub Targetting(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles gridPanel.MouseDoubleClick

My 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:

I have created a (kind of) 'Desktop' Form for the main basis of my program. Basically it is made up of 3 panel controls.
1. Holds all buttons which load the different forms (Like the windows start menu when expanded). name: StartMenuPanel
2. Holds Information on log in deatails. name: LogCheckPanel (very thin panel at top of screen)
3. Main panel which takes up the majority of the screen (where I want the forms to load). name: MainPanel
My aim is: When a button is clicked from the 'StartMenuPanel' the form will load with-in the 'MainPanel'.
I tried changing the start position to 'centre parent', but the panels are in the way so some of the childform is overlayed by the panels.
[Code]...
When I run this I get the following error: 'Top-level control cannot be added to a control'.
I hope I've explained this well enough.

I 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.

I have a nested class, let's call it class1 and it has class2 inside it; VB.Net eg:[code]
1) How can I define X number of Class2 objects[let's call it: Node(x) array]** with NEW() subroutine called?' this raises error: dim cls2(n) as new class2 end sub.
2) How can I return actual number of Node() array? [code]Outside my class in main project I define cls1 object:[code]Now an array of class2 is created inside cls1.
3) Now,How can I access All of them[node(x) array which is created inside cls1] with all properties and methods available?
I remember I wrote a ProcessManager class with this functionality in .net 2003, nearly 4 years age, I don't have the code now.

Note: 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.

I'm trying to make custom ListBox with some graphics. Base is ItemCollection - each item contains Panel, 2x label and 2x picturebox. What each panel have to do:
- Change backcolor on MouseEnter and set color back when MouseLeave occurs.
- On MouseDown(LMB) - Panel stays "selected" - different color.
Problem: I can't access multiple panels at a time(and I need to), just one via sender as in function. Of course, I can do it hacky way, but I want to do it effective and regular. Is ItemCollection the right solution or should I do it just like an array of panels? Also I want them in one "box", ItemCollection is good for it.
Second "problem": I need to make labels "merged" in panels, when i MouseEnter them(labels), background color on that panel sets to my default color. when i MouseClick them(labels), nothing happens (need to "select" parent panel). It can be again fixed with hacky way, just disable labels - but then the colors of labels are unchangeable.

I have been working on a small text editor where you can have more than one file open in the same form. When you click new, it adds a ToolStripSplitButton to a MenuStrip and makes a new form2 as a child.
My question is, when I click the ToolStripSplitButton, I want the MDI child that "owns" that button to come to the top. This is the code for adding the buttons:
Private Sub NewToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewToolStripMenuItem.Click
Dim f As New Form2()
[Code].....
All I have to show to front is Me.BringToFront() (in form2) but that doesn't do it. I have been looking for a long time now to find the answer. How can I bring it to the front?

I 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

how to retrieve child windows so I can click a button.The APIs I am using to get child windows are these:
ParentWindow:
VB.NET
Private Declare Function FindWindow _ Lib "user32" _ Alias "FindWindowA" ( _ ByVal lpClassName As String, _ ByVal lpWindowName As String) _ As Integer
[code]....
Which seems even more loosely defined. I have no idea how to actually use that function with EnumChildWindows or how its parameters are supposed to be used.The description says it's used to enumerate ChildWindows, but isn't that the whole point of the EnumChildWindows API?

I have a MenuStrip with File > New, Open, Save, Exit located in a parent form, and a RichTextBox located in a child form.The problem I'm running into is concerned with the destination of the file elected from "Open" and the save.When a user selects their file from "Open", I need it to open the child form and put the text into the RichTextBox.I also need the program to be able to "Save" from a child form, whether it's been brought up via "New" or "Open".
