proper image alpha layer when form is invisible - ๖ۣۜErexo - Feb 21, 2017

I'm looking for a way to have images on invisible form that allow alpha transparency and allow to place and use buttons/labels etc.

I've tried this Transparent background on winforms?, layered window and many more, nothing fully successful. I've ended up with such failures https://imgur.com/a/t6nmF
Other "solution" I found is to create additional form that's layered window i.imgur.com/Q231QPX.png Two forms complex into one application, will this work? how?
Any ideas ?

Use WPF for this, its very simple

1. Create a WPF Window
2. Set WindowStyle to "None"
3. Set AllowTransparency to "True"
4. Set Background to "Transparent"

xaml:

I encourage you to start moving to WPF, not only for dessign features.

Anyway if you want to stay in GDI/Winforms, my previous post image sample was done (4 years ago) in Winforms. Let me know and I will PMed you with info

I completly understand and I've done this, but the problem is I dont know how to add events to objects such as onClick, MouseMove etc (to make the program move when drag by image). Any good basic tutorial in how to switch from Windows Forms into WPF ?
Thanks for response guys.

@edit
okay I've managed to do some events, if I have any more questions I'll ask

Let's assume you have a Button.
You can either double click on it and the click event gets generated,
or you write it like this

Code 
<Button Content="ClickMe" Click="YourFunction" />

and then in the code

Code 
public void YourFunction(object sender, EventArgs e){

     //CODE

}

Now I want to create a custom progress bar, I have two images, empty and filled. How to combine those two into progress bar? I've searched web for a while,
I've eventried to do this by layering two images. Do you have any idea?

Do you have discord so I can help you ?
Because this requires Styles and advanced WPF knowledge, i can do it for you.
