when I run a display alert, or a system alert is displayed I get
realize there is a little animation, from the window displayed, is there any way to do this with an image
(ImageView) programmatically without using a gif image?

I'm working on a WinUI3 desktop application in c++. I was trying to achieve an experience where we can show a ProgressRing in the center of the screen when there is a delay in screen update. In my application, my window has a Canvas as its content and that canvas contains many widgets. I want to put a new Canvas as an overlay on top of the existing Canvas and show a ProgressRing on the new Overlay Canvas and I was able to achieve an experience like this.
The overlay Canvas in the image has a background color as transparent, I wanted to make the overlay canvas translucent. So that all the widgets below the overlay canvas will look like grayed-out non-interactive widgets.
I would be of great help if you could help me with this issue.
Thank you,

One way to do that is to set the Background("Black" maybe?) and the Opacity depending on how you want it to look.
I have a CListCtrl in Report View that displays a series of images (192px X 192px) that a user can click and select. When the window is resized, I can see more of the images vertically, but not horizontally. What can I do to reposition the images. I dynamically generate these images and add the CBitmaps to the image list, if that helps. They are not icons in the Windows sense
So I was following this tutorial, https://deadbird.fr/?p=800, to obtain blur behind windows in qt.. Made some changes like request a capture() when a resize event is scheduled and added a timer to update every 200ms the image with QTimer so when for example a window is minimized the background image is updated. So far so good..
But then I tested the timer and I noticed this: https://www.youtube.com/watch?v=WixIShA48jg
As you can see in the sixth second of the video the QGraphicsScene is overlapping the images, even with scene->clear();
The other problem I have is the color. I changed the background color of the dialog to blue but only the borders are blue. I also tried to put the QGraphicsView in a QFrame with transparency and blue color but no luck. Why is that?
You can find the source code in the tutorial site. My changes are visible in the video. The video is also in 720p.
When exactly is WM_PAINT called? Im trying to create a dialog based slot machine application, but i've run into a couple of logical issues. My application will consist of:
"Spin" Button
Exit Button
Three BMP images to display the results of the spin(coin/heart/soldier)
How will i show the final result of the spin using the BMP images? Am i correct in using WM_PAINT to attempt to display the images, how will i refresh the screen each time the user presses the spin button to show the new images? I really appreciate the help!
Dialog boxes normally use DefDlgProc as the window procedure. You can't handle WM_PAINT in your DialogProc (it isn't a window procedure). You can use your own window procedure with a dialog but that's probably more trouble than it's worth.
The simplest way to display a bitmap on a dialog is to use a static control with the SS_BITMAP style.
You can change the displayed bitmap by sending the STM_SETIMAGE message to the static control. The control will take care of repainting itself with the new bitmap.
This is OK if you just want to display the result of a spin, but won't work very well if you want to animate the spinning of the reels. To handle this you could create your own static control (i.e. a window for each reel) that would display a portion of a reel bitmap.
I need to create a progress bar with rounded corners in a MFC application. I have tried using a combination of CreateRoundRectRgn() and SetWindowRgn(), which has the effect of making the control disappear completely. I also tried using a transparent GIF overlay that would be drawn on top of the progress bar, but I could only get the overlay to be drawn behind the progress bar. Any suggestions?
