picturebox

问题 I am currently using Visual Studio, and I don't know if this is a glitch or not, but when I go into the form properties, and show the events, there are two events called KeyDown and KeyUp . Now when I do the same for a PictureBox , it has way less events and no KeyDown and KeyUp events. Does the PictureBox support less events then other things? Is this a glitch? Screenshot of Form1 properties: Screenshot of PictureBox1 properties: 回答1: Its not a glitch. Its the way it is. You don't type in

问题 I want to drag a PictureBox, and I have managed to do so. But my application doesn't do it as smoothly as Windows photo viewer. I mean the difference isn't huge or anything, but it's noticeable. Is there something I could do to make it a little less choppy? This is my simple code: int MOUSE_X = 0; int MOUSE_Y = 0; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { picBox.Image = Image.FromFile(@"D:\test_big.png"); picBox.Width = 3300; picBox.Height

问题 I'm using Picturebox control as a Button in my app's main dashboard. The PictureBox has of course an Image that identifies the Button function. If I use normal Button controls, when disabled, the Buttons' Image it grayed out automatically. This doesn't happen using a PictureBox. How can I generated the same effect using a Picturebox. 回答1: Option 1: CustomControl (PictureBox) + ColorMatrix Since you don't want to use a Button, which would gray-out the Image for you when the Control is disabled
