I need to use a blinking icon as an image for a specific item in a tree view. For this, i tried to add an animated gif file including two frames, one including the image and one an empty frame. I could add the image to the image list in designer. But it doesn't blink. I tried to figure out what's the problem, but i couldn't.
Any idea?
Default Windows Form does not support any animation, that's why gif file look like static image, when we use it in windows forms. If you are using windows form, then use timer control to redraw the treeview. Or use integrated wpf content in windows form(my choice)

I am currently creating an OS using Cosmos Kit. I have created the GUI, and now I want to add a menu bar. I have created an image of how it should like but I don't know how to add that image to top-left corner and use it as a button. And secondly, add some text to that.
IMPORTANT:
I don't work in Windows Forms Application, so I only program it.
Thanks, Joe.
By default, Windows shows the a thumbnail of the whole window as preview in the taskbar. I want to replace the default thumbnail by a custom drawn replacement. How can I do it?
I found TaskbarItemInfo.ThumbnailClipMargin, but this property can only cut the thumbnail. I want to show a completely different content (in my case some TextBlock controls). I'm using .NET 4.5 for my WPF application.
Background
I want to drag "icons" from the desktop on to my form, they will then be visualised on the form, not changing in appearance.
When i say "icon", i mean shortcuts, folders and application icons.

Question
What is the best way of recreating the icons on the form. Is there a tried and tested way, or do you have to recreated them using picture
boxes and labels?
What I've Tried so Far?
Picture boxes
Forms
I've had limited success with both, with the latter being the best so far. However both have their limitations.
Notes.
I do not need help with other areas of my problem like, how to drag icons, extracting icons, etc. It's purely just recreating the icon visually i'm struggling with.
Use a ListView and set the view property to LargeIcon.
You can obtain the icons through: Icon.ExtractAssociatedIcon. However, you may need to manage the icons as two files with the same extension may have different icons.
If you only want the image, then you can grab just the icon portion of the control after it's painted.
I'm making C# application design with images, but when I launch it, I see loading images (~1sec), so how to make simple loader, when images (background, logo, etc..) fully loads, to show my app? I know it's possible but I don't know how to. Thanks so much!
This sounds like standard behaviour. The controls get painted one by one in z-order and if one is slow the rest may appear to flicker.
You could try double buffering the whole form as shown here:

Alternatively you could suspend the layout while everything is drawn and resume it afterwards:

I'm writing a windows 8 app wich basically does nothing when you open it (everything is done in background task and the user doesn't see it) so I need to display a kind of slideshow on the main page of the app just so it looks like something and not just a blank page.
My problem is I can't use the pivot app template, I need to start from a blank template.
So I'd like to know what is the most simple way of doing this ? By the way, I need the slideshow to switch between the images automatically (with a timer that I can set) but the user can switch himself if he wants to
Thank you :)
You say You can't use the pivot app template and want to start using a blank template.
You can however add pivot as a control once you start with a blank template.
If Not using pivot is your aim, then try panorama.
Start from a blank template and add panorama control to it. Panorama can also help you to get a nice sliding effect like in a slideshow.
you can have images in stackpanel and detect Flick Gestures whether left to right or viceversa through HorizontalVelocity of Flick events.
