Hi Guys, I'm writing a small Login dialog, and have embedded a banner at the top of the dialog for aesthetic reasons. All went well, except that by default, WPF anti aliases the entire image, making the text that was contained within it frustrating blurry. After a bit of Googlin', the first few pages of results showed that it's common ...

If i set sizetocontent to widthandheight, then WindowStartupLocation="CenterOwner" does not work properly. Instead of the center of the new window to be at the center of its parent owner, it looks more like the top left hand corner of the child window to be at the center of the parent.

Hi Everyone, I have a few 3d rectangles on my screen that I want to pivot around the Y axis. I want to press down with the mouse, and rotate the 3d object to a max rotation, but when the user moves their mouse, I want to slightly rotate it so that it looks like a see-saw (rotating from a range of -13 to 13 degrees on the Y-Axis). At ...

I can easily prevent duplicate entries in the listbox when a new item is added because I can check for it in the "Add" button's Click event handler. However, when an existing item's ...
