vb.net, visual studio 2005, windows forms
My application dynamically creates controls and adds them to a panel on a
form. This is done in the form load event.
I don't know if I would call it flickering, but parts of some controls get
displayed before others. They don't exactly flicker, they just appear in
pieces, instead of all at once. The controls include nested panels. I have
tried to avoid TableLayoutPane ls because the performance is so terrible.
Before I add the controls, I suspend layout for the form and the panel. The
form is double-buffered.
I also tried setting the panel.visible = false and then true when the
contols were all created and added to the panel, but it doesn't help.
It looks funky while the page is loading, although it loads fast so its not
too bad.
I would like to fix this, and I would appreciate any suggestions.
Thanks
Bill

In a similar setting, I have a form with an empty TabControl. In the form's
load event, I add several panels, and on each panel I add about 20 controls.
I get a good draw by setting the form.visible to false at the beginning of
the form load event, and true at the bottom.
IMO, the flicker you are experiencing comes from more than one drawing
operation being performed in rapid succession. There is at least one draw
because of what you are doing in the load event, and later there is another
draw caused by .net/windows. The way to stop this is to run the load event
with the form's visible set to false. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hi all.
I'm learning VB.Net and am developing a WinForms app.
I'm trying to make an app that I will use to scan in one or more than
on image. I want to use a tabbed interface to hold each image. Here's
the code I'm using for testing purposes. I've got the code in the
form's load event, but I think I'd have the same problems no matter
where the code existed. Right now, the form has an empty tab control,
everthing else is dynamic.

Hi Everyone,
Does anyone know where I can get my hands on a sample with source code of a
simple dynamic button control in C# Windows form. I am looking for a sample
that uses a class library that sets the properties send/passed from the main
windows form. I'm having problems with the class library, the button control
collection and my referencing it ie this.Control.Add(aControl);.
Any and all help is appreciated. Thanks in advance.

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,...
