I want to make my application so that when it has been maximized the control will automatically position itself it the right place.
Assuming that this is a WinForm project, you need to set the Anchor property of the button to Bottom, Right.
The most useful control is the TableLayoutPanel. You should put all the controls on the panel -> set dock: Full and every time the form resized, the controls stay in their container.

I am using Visual basic 2010 for coding. I have develop the code on desktop. Where I have adjusted form as per my desktop screen. I am going to run the application on Laptop. When I run the app the screen is not fitting to Laptop screen. SO I deciede to include vertical scroll. If moved up and down we can see all the parameter.
How can I do it?
I have added image for reference.
The scroll bar(s) should be inside the individual TabPages. You should set the Anchor and/or Dock properties of the TabControl so that it resizes with the form and set the AutoScroll property of each TabPage to True if you want it to display scroll bars if and when any of its child controls are outside its viewable area.
I created an interface it has several forms you can switch between using a panel as the parent form. My problem is that when i switch between my forms on the second time i open a form if that form has autoscroll on a panel it will not allow you to scroll and the window is stuck on the view you previously had.
In this image i open the form internet. after doing so i will click on instruction( any form switch triggers this)
now i open the same form again and the scroll bar is gone and it locks in on the last position the form was in.
the very curious thing in this is that this only happens on the internet form word also has a scroll bar however even though the properties and settings for both are identical only one does not work.
What could be causing this and how do i go about troubleshooting errors like this.
The forms are removed from the panel and re-added, they are not closed.

closed.
Store the state of panel autoscroll and set it after you have re-added it. Note that if you add controls to the panel first and panel is not docked, then scroll will not appear because panel dimensions can be huge. You should set following property as well:
vScrollBar1.Vericalscroll.Value = 0
Assumption 1:
I assume what is actually going on is that you do not add controls to that panel, but to the form behind it or something similar. In that case - program is correct, you just asked it to do a wrong thing.
Assumption 2:
Assuming is panel is anchored top, left, bottom, right. There is currently a limitation in Windows Forms that prevents all classes derived from ScrollableControl from acting properly when both RightToLeft is enabled and AutoScroll is set to True.

Assumption 3:
You add the controls back, by recreating them, but forget to add handlers or create them in order where scrollbar is out of view. Instead of absolute positions you could use dockstyle:
Dim vScrollBar1 As VScrollBar = New VScrollBar
vScrollBar1.Dock = DockStyle.Right
Controls.Add(vScrollBar1)
I am trying to make a transparent control with child controls that are visible and opaque.
I have added a panel control to the main form via code in the form load event. In this I am adding five buttons as child controls like: panel.controls.add(). To all of these, I have set backcolor=color.transparent.
When I run this program, the button background shows the background of the next button in the panel. If I open a child form, then I can see labels on the child form as the background of the panel.
I want to make container panel control completely transparent, so I can see the main form through it. How can this be achieved?
When the form loads, you can see neighbor buttons behind the actual buttons
"Perform Check" is a label on a child form which I opened right before taking this picture.
: "Check Cases and Combinations" is a button on a child form which I opened right before I took this picture.
How can I make it truly transparent? Why doesn't the background of the panel control refresh with the main form background? The panel sort of "keeps" whatever happens on the main form and shows it as a background.
I found out there some issues with setting controls that are transparent and on top of other controls in the main form. They take the background of the container form, whether or not there is any control in between. I used WPF form instead of the panel and it worked perfectly.
I have a VB.NET form that dynamically creates a set of controls. If there are too many controls to view on the form, the form will show a scroll bar. (It is an autoscroll form.)
The user can scroll down and click a button which causes the form to change dramatically. It destroys all controls and draws new ones based on user input.
I've noticed that if the user is scrolled to the bottom of the form and click the button, when I destroy and create new controls they aren't located where I want them. It seems to put them relative to the visible portion of the form rather than the top of the top.
Example:
checkbox1.top = 50
checkbox1.left = 15
If the scrollbar is all the way at the bottom, the checkbox should be placed above the visible part of the form. Instead, it is drawn 50 pixels from the top of what I can see.
Please help. How do I make it place the control at an absolute location, rather than being relative to the current position of the scrollbar?
You have to compensate for the scroll position of the container control.
If a panel, then it would look like this:
checkbox1.Top = Panel1.AutoScrollPosition.Y + 50
Alternatively, you could just use a FlowLayoutPanel control, which would handle the placement of the controls for you.
I am trying to create an application that will start up over the Windows' taskbar on the bottom left corner. I want the form to overlap the taskbar. All my methods ends on making the form load above the taskbar.
You can set the form's property TopMost to true to achieve that
