I have a basic form with four objects placed on it: a Menustrip(Dock = Top), a ToolStrip(Dock = Top), a SplitContainer(Dock = None) and a StatusStrip(Dock = Bottom). As it is now, the MenuStrip, ToolStrip and StatusStrip are exactly where I want them. The problem occurs when I set the SplitContainer dock property to Fill. I thought it would fill the remaining area but it fills the entire form, you can see the outline of it beneath the menu and status strips. Is there something I'm missing in another property box or is there a different way of doing this? The reason I want to set it to Fill is for autosizing when I resize the form.

I'm trying to dock my form to the top of the screen, but not as a desktop toolbar. There must be a simple way or a property... I just want it to start on the very top center of the desktop, I can't figure out how?

Whenever I load or close child forms or other form (for that matter) then there is flickering in my MDI form. The flickering maybe because the form may be getting painted with gradient or so. Now this flickering is really noticable and I need to solve this. I am pasting the code that I am using to paint my MDI form. If you guys think the code is in efficient then let me know. Or if there is any fix or other way to go about it then I would like to know.
CODE - written inside my MDI form.
Public Class MdiContainer
Inherits Control
Private WithEvents MdiPane As Control

Basically the form moves to the bottom of the screen so that the bottom of the form is at the bottom of the screen. It the increases the width of the form until it is the width of the screen. The height stays the same. So it fills the bottom of the screen.

I am new to VB 2008 programming The first project I've been tasked with is creating a ticker/notice-board for our office - which will show Horizontaly scrolling updates of incidents being reported. I'm ok with the scrolling, keeping on top etc - but what I am unable to do is make my form dock to the top of the desktop window, and make any other applications windows smaller.
So that when any other application is maximized, it's window will not go behind my ticker application - so people can still easily use any other applications toolbar etc. Is this possible to do in VB 2008?

I need to create an on-screen shape (circle) that has a fill color, which will blink every X seconds (go from fill color, to white, back to fill color). This is trivial to do...BUT... i want to do it in my own class, so that I can instantiate it numerous times passing it unique coordinates for each instantiation.
How do I do it? Can a class have its own "timer control" in it independent from the form? How would I draw a shape from a class?

I know how to dock a component using the windows forms designer as well as through code but I am having a problem with one thing. I am trying to dock a richtextbox on a panel through code but it seems to be filling up all of the space instead of just the panel. When I put it on the form and dock it works fine. The code I am using is:

From this forum I saw some discussions about form/controls resizing issue with different resolution screen setting. Most suggestions are using Anchor/Dock. My application's form has 10 group boxes and some buttons. In each group box there are 5 Text boxes and other more controls. I tried anchor and dock but couldn't make it work. My questions are -
1, How to re-size form and all individual controls as well?
2, If anchor/Dock are suggested, do i have to use both of them or just one? it seems to me there is no big difference between them.

I have a button btnRegEx that when pressed shows a ContextMenuStrip, similar to the '>' button in the Find/Replace dialog in Visual Studio when you are using Regular Expressions. I have a ContextMenuStrip cms which I show using its Show(x,y) method.
At first I was simply setting x and y (the location of the ContextMenuStrip) to some point next to the button, but I noticed that when the button is close to the edge of the screen it goes off screen. I wanted to prevent that so I built some logic into the x-y calculation. When the ContextMenuStrip width is larger than the 'remaining space left' I simply show it more to the left. Same for its Height of course. I am using the Screen.GetWorkingArea(point) method to determine the 'remaining space left'. As I understand it, it returns the working area closest to the point you specify (to which I pass the button's location).
As long as I stay on my first monitor, it is all working perfectly fine. The problem occurs when I move the form to my second monitor. The contextmenustrip is still showing on the first monitor for some reason...
Here is the code I am using:
vb.net Private Sub btnRegEx_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRegEx.Click
Dim p As Point = PointToScreen(New Point(btnRegEx.Left, btnRegEx.Top))
Dim x, y As Integer
[CODE]...
I have noticed that when I click the button when the form is on the second monitor, the buttons location (p) is calculated with the first monitor's top-left corner as (0,0), even though it is on the second monitor. This way, the GetWorkingArea function returns something like 1280, while the buttons x-location is something like 1700... So, how do I get the buttons coordinate relative to the actual screen it is on, rather than the entire dual monitor screens as a whole?

I am trying to make a style that only gets applied if the parent element of the element that the style refers to, has another specific style. Kind of like in CSS where you can do ".class1 .class2" to specify that the "class2" theme only applies if it is within an element with the class "class1". I do not wish to use any form of external DLLs or libraries for this task. I want to know if it's possible to implement on my own.
I've tried using MultiTriggers with no luck. I have a style that applies to all TextBlocks. I want the textblock to do the following: If the font-size of the textblock is 11 and the parent element's style is "PinnedSuggestion", set the foreground color to "#FF505050". If the font-size of the textblock is 11 and the parent element's style is "Suggestion", set the foreground color to "#FFCCCCCC". The conditions that I have tried to write to make this work, are as follows (the font-size condition is true, but the other one is not). The conditions are inside a style that applies to all textblocks in general.

BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

I have just run into an issue of screen flicker that I haven't been able to solve. I have a panel with dozens of controls on it. Painted onto the panel, behind the controls, are a few colored rectangles.
Those rectangles flicker whenever the mouse is moved over any control, or off the panel. Basically, a paint event for the panel is raised whenever the mouse leaves the panel.
Therefore, I thought that if I only painted the rectangles when they needed to be painted, not every time the Paint event was raised, that I would be able to avoid the flicker. After all, there is no obvious reason why they would need to be re-painted just because the mouse moved over a control on the panel.
the paint event was still being raised, and the panel just wasn't painting the rectangles, so they weren't being drawn at all (but they sure didn't flicker). So, the flicker is being caused by the fact that the paint event clears the panel, which gets displayed in a cleared state for a fraction of a second, then the rectangles are drawn in.
Doublebuffering the form has no discernible impact, which may well be because the screen draws the absence of the rectangles on one frame, then draws the presence of the rectangles on the next frame. They both get shown in sequence, so the rectangles appear to flicker badly.
One obvious alternative is to not even draw the rectangles, which works great, and they are only useful visual guides, not essential components. Still, that doesn't seem like a good solution.
So what I am looking for is a way to supress the display of the undrawn image before showing the finished image.
