vb.net unwanted richtextbox resizing - vb.net

i have two richtextboxes of the exact same size located on my form. However, when I run it, one's height reduces. There are other controls around it so it leaves a weird space. What causes that?
Form in the Design tab
Form once I run it
I've tried constraining the control with the "same height" button, I've created a new richtextbox, but it keeps on happening.
It also depends on computers, on screens with unusual resolutions the box is the correct size.
Thank you

Its because scroll bar coming in picture. In order to uniformly set the positions and sizes of RichtextBoxes use DOCKING or Anchoring properly

Make Form Maximized, but not Full Screen

I would like to make my Form1 Maximized, but not Full Screen, as differentiated by Maximized taking the entirety of the screen while leaving space dedicated to the Taskbar at the bottom. To clarify, I'd like my application to work how other applications traditionally work, such as Chrome or the MS Office suite when maximized. Definitely nothing fancy.
To make my application resize itself dynamically, I've calculated where buttons will fit relative to the height and width of the application. However, I discovered quickly that my application, in Maximized state, actually continued underneath the task bar (or, in reverse, the taskbar is entirely cut off by the application - it is Full Screen). My bottom-most buttons are actually cut off by the taskbar. After experimenting with different Form settings, I discovered this appears to be entirely the result of WindowState = FormWindowState.Maximized setting.
I've tried various routes to counteract this behavior. First, I attempted to resize the maximum bounds programmatically, while leaving the Form's MaximumSize set to "0,0" (the default "resize me as needed" setting). I have this code in the Form_Load event:
Me.MaximizedBounds = Screen.PrimaryScreen.WorkingArea
and
Me.MaximizedBounds = Screen.FromHandle(Me.Handle).WorkingArea
However, these did not have any affect, even though the working area height is confirmed smaller than the form height. In fact, upon further testing, I have not been able to programmatically change the maximizedbounds at all, apart from manually in the form properties, setting the MaximumSize to 100,100. Does anyone have suggestions here?
I also tried to change the WindowsState = FormWindowState.Manual and readjust the form height this way:
Width = Screen.PrimaryScreen.WorkingArea.Width
Height = Screen.PrimaryScreen.WorkingArea.Height
Which makes the form closer to the dedicated dimensions, but makes the window movable and no longer covers the entirety of a traditionally maximized screen (it leaves about 20 pixels padding on all sides).
In the end, I'm at a bit of a loss on how to do this and would really appreciate some clarification. I have attempted other code I'd be glad to share, as well as similar questions on the forum, but none have helped me get my targeted behavior. I have a locked Taskbar on the most recent update to Windows 10, if those details make any difference.

how to resize or reposition controls based on screen resolutions in VB.NET

I making a Windows application with VS2010. Where i'm using panels to fight with different screen resolutions.
For some of my controls I used anchor property set to top,bottom without docking them to parent panel. when i run this program on the machine which is used to develop, result was as expected,But when i tried this one on different resolution its results were worse than expected. Some controls are partially displayed.
I found a solution here to this by re-sizing my controls based on screen resolutions. But that didn't worked for me as controls were re-sized but they were out of display area.
I couldn't relocate them based on resolution.
how would i set their position based on resolution.
or
i should assume minimum screen resolution (lets say 800*600) and program with this resolution.
Plz help!
I thought the solution was to use TableLayoutPanel and panels to do this.
I was bit right, but this doesn't work in all the cases.
Found a solution here https://stackoverflow.com/questions/2802015/....

AutoScaling WinForm Display (Small, Medium)

First and foremost, please forgive me but my screenshots are in French due to my Windows installation at work. It is still very easy to understand though. I'll include screenshots to make it more visually appealing.
Here's some background information:
Windows 7 64bit
Visual Studio 2010
Default display is 100%
AutoScaleMode: DPI
AutoSize: True
My application is a windows form that was developped in a default (small - 100%) display. Like so:
As you can see, the "Petite" or Small display is the default selection.
Small Display - 100% (default)
Here is how my application looks with this setting. This is the correct display
Medium Display - 125%
The red rectangles point out the unwanted empty space.
I have tried:
Anchoring / Docking my controls such as my split containers, table layout panels, list views on Form_Load and via the UI. This didn't work.
Adding a split container to the form, and all controls respectively separated into it
Adding Table layout panels, where all textboxes and buttons are located in their respective cells
I really thought it was having a scaling problem because of the anchoring and docking. Although that didn't seem to be the problem ... What seems to be having trouble is the Tab Control and Listviews ...
Some users (most) have their settings as the default (100%) but there are a few who have it at a Medium setting, causing this scaling issue. Is there a way to fix this?
I cant see your screenshots or links for some reason so I cannot visualize the problem. If scaling is the problem, try setting AutoScaleMode to None.
I recently had to do this because my winform app was image intensive and it would not render correctly on Medium Settings because I built it using the default Small Settnigs display. Changing scale mode to None worked for me.
I fixed my issue by putting the tab controls and list views in a tablelayoutpanel. Everything that wasn't scaled properly had to be put inside a TableLayoutPanel. I kept my AutoScaleMode to DPI and AutoSize to True
Be sure to dock everything in their parent containers.
Here's the document outline for the more visual (like me):
Just click on the form and go to property pane. Find the Anchor element and click the dropdown. You click on all the lines in the square structure to become grey. Then click enter. Problem resolved.

two nearly identical usercontrols with different resize behavior

I have an application which has a tabcontrol that contains two tabpages. I have a custom made usercontrol docked to fill up each of those tabs. When I resize my main form to the minimum size allowed one tab resizes accordingly while the other seems to overflow the area and a couple ui items slip out of access/view.
One usercontrol was quite literally copied from the other and renamed and fields adjusted. The usercontrol size is the same between the two. Within the usercontrols there is a datagridview and a large panel full of textboxes and they have identical sizes and identical anchoring properties and even the same location coordinates.
I'm struggling to find a difference between the two but I really would like the resize behavior to match between the two usercontrols. I was wondering if anyone would have ideas of other things to check I did not mention here?
This should like very odd behavior.
There are a few things that I can think of to check:
1) Double-check that the user control is actually on the tab page itself and not on a different control, such as the tab or a common tab area (not sure of the tab control you are using; some controls have a common area that is available to all tabs).
2) Verify that the Dock property is indeed set to fill on the "bad" usercontrol.
3) Verify that you are not resizing or changing the Dock property on the bad usercontrol in code.
Found a minimum size on one of the usercontrols and that was the cause of my issue. Don't know how I didn't see it earlier.

Controls change place and form size changes

I have designed a form in VB.NET. At design time I have placed two buttons on it.
When I run it, the form size looks smaller and the buttons I have placed at the bottom are not visible. Also the alignment of the text and picture box is also different from what I set at design time.
Computer at which I am running the form is using a different resolution.
change the properties (F4) of the buttons: in ANCHOR put Bottom, Right
your buttons will be tied to the bottom and the right of the screen, instead of to the top, left, which is the default.
Grab the screen size at runtime with
Dim screen as System.Windows.Forms.Screen = System.Windows.Forms.Screen.PrimaryScreen
and using a scale factor depending on the current size (in design), scale the window to match. Check the coordinates of the buttons by hand to make sure they are not outside of the visible portion of the window.
You may not have to leave this feature in if you can debug it to the point that you know the exact resolution that you need.
