I am trying to create a form with a 500 x 500 form size.
Then I create a panel with a 500 x 500 size.
Logically, the panel size would be the same as the form size.
However, the panel turns out to be significantly larger than the form.
This gave me the conclusion that the form size turns much smaller than the given size which is 500 x 500.
How do I make the form size have the accurate size instead of having it smaller than the given size (e.g. 500 x 500)?
Here is a video that I’ve made to give you guys a clear picture of my problem.

The form size refers to the outer edge. The form has a resize border all around it plus a title bar where you cannot place controls. The remaining part inside is the ClientRectangle. You can get its size through
frm.ClientRectangle.Size
' or inside the form itself
ClientRectangle.Size
If you set your panels Dock property to DockStyle.Fill, it will automatically fill up the whole available space. You can do so in the designer in the properties window through a graphical input or in code. The Size property, in this case, is irrelevant.
If you add serveral docked controls, the sequence matters. The fist ones will occupy the outer edges, if docked to some edge.

I'm having difficulty with resizing controls in two panels...
I have a form with two panels stacked on top of each other. The top panel takes up 38% of the form and the bottom panel takes up 58% of the form and a 4% gap between.I have a tab control in one and group box in the other.
I've been trying to perform fills/docks within the panels that will cause all controls to grow and shrink with the panel's size. In other words I'm trying to keep the same space and size percents for all controls based on the form size. Visual studios keeps crashing when trying different fills/docks and I don't want to calculate size percents and x/y coordinates for each control. Is there a way to set up the fill within the panel or container so that it looks almost the same at most sizes?
In my experience, docking causes more problems than it helps. What I do instead, is undock the controls and then anchor them on all sides. Then I size them within the panel how I want them. Then, if the panel is ever resized, the controls anchored within them will resize accordingly and it will stay within the boundaries like I want it to. Try that.
I am doing a WinForms program which should have a fully responsive design in a full screen.
I get an approach which works more or less well. It consists into calculate a ratio between display screen and original form size.
Then I apply this ratio to the width, left, height, top properties of each control inside the form.
My doubt is about to use a native way for doing this, since, using anchors, the controls keep their same distances with parent control borders, but I doesn't do proportionally, for instance:
Form with 100x100
Button 20x20 located in (10,10)
If I resized the form to 200x200 (multiply by 2), the best approach I can do in design view is keeping the four anchors to the button, so button size will be 120x120 at the same position (10,10), while what I need is a button with size 40x40, at position (20,20), since form size was multiply by 2.
Is it possible with winforms native operations in design view? (Avoiding to make calculations)
Yes it is possible.
Using the Property Dock = Fill you can ask for a component to take all the room in its container.
Now using a TableLayoutPanel, you can define cells to put your components in. And giving cell a percentage size, you can make sure the sizes will change when the form is resized...

Microsoft Access seems to limit the form width. This limit is ->very-< small...
Is there any way to bypass this limit?
I try to create a dynamic datasheet view which allows background coloring of rows, onClick events in specific fields, Locking of specific fields, logging of changes etc. I'm using a continous form, that dynamically defines field width, events, sorting, color and position to create this perfekt table, which works really well.
The only limitation for this I've found is the max form width, wich seems to be a simple integer, 32.767 . The size of this seems to be ->much<- smaller than a pixel (I've heard it's 567 per cm.), and so it limits at about 1.2 screen witdh of a HD screen. Thats WAY to small...
I'm not sure what you mean by 32.767 being smaller than a pixel? The max width for a form is 22 inches which is 31680 twips. That is ~1.2x the with of my monitor; you're right. But that seems pretty darn wide. Certainly not very small.
If you need wider than that you can use datasheet view for data entry, or multiple rows of controls in your continuous form, or multiple screens (i.e. tab ontrol, let the users click 'Next' to fill out more data).
This is a logical width to keep you from shooting your self in the foot. People don't like to scroll to the side a lot.
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.
I have a RDLC report and I am displaying it on the Report Viewer Control in my front end application. I am able to view the report perfectly.
But the problem arises when I try to export the report to a PDF (using the built-in option).
I print the report in 3 pages whereas my client wants it to be in a single page. I can't figure out the reason for it as in my report viewer I see only one page but in a PDF there are 3 pages.
Can something be done about it so that I can control the size of the report?
The answer is pretty similar to what Dugan said, but it's not always just the margins.
It is pretty simple though:
When you are editing the rdlc file in design mode, firstly click on an empty part of the BODY area of your design. Hit F4 to see the properties tab. Here, you will see a "Size" property. This can be expanded for the width and height. The width you see here represents the width that the body of your report requires as printable area. Even if you have white space all over, the page knows that it needs to keep it as a printable area. It reserves the space, in some sense. As for the height, the system generally knows that it can grow or shrink as necessary, unless you have specified otherwise within your controls therein. So the width is what will, usually, play the most important role.
Next, click on an empty area of the report (outside the header, body, and footer; basically the gray area around the design), then hit F4 to view the properties panel. Under the "Layout" category of the properties, you will see 3 different options:
InteractiveSize,
Margins,
PageSize.
Each of those Size attributes can be expanded to show the Width and Height. The Margins attribute can be expanded for the left/right/top/bottom.
Basically, the pdf export works out of the PageSize (though I generally try to keep Interactive and Page size equal). When the pdf file is rendered via the ReportViewer's built-in export function, the width and height of each "page" within the pdf will be determined by the width and height in the report's PageSize attribute (you could override this if you used your own custom code for the pdf rendering).
As for the margins, they specify how much space MUST be left blank and unprintable between the printable area reserved for your report and the edge of the page.
In other words:
Your report's Body's Width, Plus the Report's Left Margin, Plus the Report's Right Margin, MUST be smaller than or equal to the Report's PageSize's Width!
So...if your margins are too wide, or if your report's body is too wide, or if the PageSize's width is too narrow, the rendered result is forced to be broken down to multiple pages in order to fit!
For example: If my report's body has width 7.75", my Left margin is 0.5", my right margin is 0.5", and the width specified in the PageSize is 8.5", my report will always use 2 pages for each 1 page of data. The 7.75" width of the body, plus 0.5"+0.5" for the margins add up to 8.75", which is larger than the 8.5" available in my page. So the first 7.5" (or so) of each page of my report's body will be shown in the first page, and the rest will be split down to the next page. This will not be done inside the report viewer, as it allows for the report to grow beyond the page size by just adding a scrollbar, but it will be annoyingly noticeable in the pdf export.
In order to make my example report fit in 1 page, I can either try and reduce the body of my report to 7.5" or less, or I can reduce the left and right margins by a total of 0.25" or more (for example, set them to 0.3" for a total reduction of 0.4"), or I can increase the PageSize to something larger than 8.75".
Note: Acrobat Reader is pretty smart and knows about various paper sizes. Therefore, while arbitrary PageSizes will work, it is typically best to use real page sizes. As such, in my last example I would rather set the PageSize to have Width = 11" and Height = 8.5", which is a real letter-size in landscape! Adobe will typically understand this and print properly.
Also Note: Some printers, especially older ones, have trouble printing with less than 0.3" margins. If you want to be nice to your users, you should best keep the margins large enough for those older printers ;)
I hope this helps.
Always maintain body width : 7.5 or less
Left, Right Margin width less than 0.5
Set the Margin width first -> goto main menu Reports->Report Properties->Layout->change left margin and right margin
Total page width :8.5

In addtion to watching your widths, I found other unrelated things that can cause extra blank page in the PDF.
If the tablix has any field with word wrap, this can cause it. You might want to make the font smaller if you have long data. Make the font size property equal to something like this:
=iif(len(Fields!RepGroupName.Value) > 25, "6pt","8pt")
Another thing you may have to do. And this helped me when I had no apparent reason for the extra page. In the Report property page, set:
ConsumeContainerWhitespace = true
Yet another thing to watch for. The body size can grow without you knowing it while making changes to the layout. You might have to knock it back down again.
This issue is highly annoying for the end user if not resolved and annoying as heck for us to resolve.
In case anyone else runs into this issue and ends up here, it's most likely a issue with your margins. If the margins are set incorrectly, you will often get "extra" pages that appear when you try and print, whereas when you view the document everything is fine.
