How to get GetWindowSize?
GetWindowRect can do so but... because it requires the window has been shown at least once. This is a REAL headache.

setup.exe ???
What is it? Nobody dare to open.

Thank you explanations.
Have you studied how to park the Form at exact position considering the thickness of Aero edge?

I have no knowledge on ElementHost. I used to use dsoframer.ocx (AxDSOFramer) to hold OLE Office MSWord on VB.NET app. Can ElementHost do so?

Headache to design the print preview window due to Dpi reason. For a user window, if we drag from 96dpi to another 168dpi, everything should enlarge in proportions for DpiAware/DpiAwareness. But for...

The preview is customized, not use .NET's PrintPreviewDialog.

I also have such feeling at first. When I get used, I am OK.

Our famous LeandroA's ucGridPlus also used CarlesPV 's ucScrollbar, I can see the Theme is not working on Win11 or Win10.

The form (e.g. for Print Preview) have to set Maximize when the form start showing, MaximizeBox is True and the form is Resizable. That is the reason I have such problem. MS doesn't provide such...

[VB6] Smooth Scrollbar Control v1.0.9b (updated 11/12/19) by shagratt

For WYSIWYG printing, the picturebox size in pixel will follow the actual paper size computed by some factors such as Screen Dpi and zoom factor.

Let's say we use one Picturebox as print preview canvas. If we print on A4 paper and the zoom is 100% , does the Picturebox need to resize to 21.0 x 29.7 cm (for Dpi 96, 793x1122 in pixel) for best...

My form's start up sets to maximize and resizable:(

class Form1
{
private const int WM_NCLBUTTONDBLCLK = 0xA3;
private const int HTCAPTION = 0x2;

Processing WM_NCLBUTTONDOWN and WM_NCHITTEST can do...but make thing complicated.

Thank you, We can subclass WM_NCLBUTTONDBLCLK then resize our Form.

How about the drag then resize behavior?

Look like there's no direct event. I have to Subclass WM_NCLBUTTONDBLCLK for double click. Still thinking what is the start drag and resizing relevant event.

When we double click or drag the caption bar, the windows automatically resize to a certain size.
My question is:
What is the event for double click the caption bar?

GetSystemMetrics(2) always returns the main display screen data. GetSystemMetricsForDpi has 2nd parameter DeviceDpi to do computation. It is useful when the window moved to the 2nd Monitor.

It's a dropdown Listbox to simulate ComboBox. But as you said, I can put a panel container and draw panel border.

One of gold rules is that we should develop our app in 96 dpi. We set the table Grid's properties like grid1.Column(2).Width = 80 and grid1.Row(2).Height = 30, but if the main screen is over 96 dpi,...

yes.
Thank you.
