I am trying to set image source to something from my computer (not in the assets). This is how I am trying to do this: Uri uri = new Uri(@"D:\Riot Games\about.png", UriKind.Absolute); ImageSource imgSource = new BitmapImage(uri); this.image1.Source = imgSource; I tried almost everything I could find in the internet but nothing seem to work. Any idea why?

@media queries and image swapping

由 喜你入骨 提交于 2019-11-27 12:28:47
I'm new to CSS and to this forum. But I've been working on a little project where I want the image in my site to completely change when the browser is resized. I've been using media-queries? but I can't seem to get it right. any thoughts/tips? In the future please add code you've tried. if it's an image tag you can use a class. Hide the second image on page load and show + hide image 1 at a certain screen size like so: HTML <img src="image.jpg" class="image1"/> <img src="image.jpg" class="image2"/> CSS .image2{ display: none; } @media only screen and (max-width: 500px){ //some value .image1{

Embedding resources (images, sound bits, etc) into a Java project then use those resources

由 你说的曾经没有我的故事 提交于 2019-11-27 07:06:05
I have searched for a method of embedding a resource in a java project (using Eclipse v3.6.0) then using that embedded resource within a control (e.g., JLabel ). I have seen methods of referencing resources from the file system. Once the project has been developed I would like to publish the application as an executable. It should be noted these executables will be deployed/launched to Windows, *NIX, and Linux platforms. I know this can be done in the Visual Studio world, but I'm very unfamiliar how to do this in Java/Eclipse IDE. As a side question, how do I get Eclipse to create the project
