DrawRectangle problem

Hi,
We have a custom control into which we add controls like labels and move
them at run time. The problem we have is that when a child control is
selected and moved, we draw a rectangle around it to identify it as
selected. The DrawRectangle works fine when the child controls is on left
half of the custom control area but fails to draw the rectangle when moved
to right half of the custom control. When placed some where in between we
see about half rectangle drawn on left side around child control. Does some
body know the strange behavior.
Regards,
Siri

I suspect that you're drawing the rectangle in the user controls paint
event. The rectangle is drawn using simple GDI+ commands and is probably
behind something like a panel that is in the user control.

Try converting the coordinates of the rectangle to screen coordinates and
using ControlPaint.Dr awReversibleFra me. That draws on the desktop and will
stomp on everything.

How do I fix this if I don't know at runtime what the child class is? I'm using Activator.CreateInstance() to load the...

Hello All, I'm trying to solve a nagging problem. The goal is to draw a rectangle over the top of all the other controls on a form. Specifically, over a ChartFX control.

I haev been able to draw the rectangle on a blank form but I cannot get it to draw on top of other controls. I have pasted in the code i am using ....

How does DrawRectangle position a rectangle w.r.t to the Rectangle passed? Lets suppose I use a pen of width 5. Are the lines centered about the passed Rectangle or is it enclosed or offset?

I've made a private sub that creates a graphic (using drawrectangle, string, line and stuff like that) inside a picturebox, so i wouldnt place it right on top of the form itself and also beeing able to move it around. I was aware that the graphic would disappear whenever you minimize or have windows on top it, but was under the impression that all i needed to do for it to stay there was to call the sub in the forms' paint event. However, this...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
