问题 Is it possible to make a heart shaped picturebox in c#? I have seen codes in making rectangle and ellipse but I don't have any idea on making a heart shaped region. Any idea? 回答1: This seems to work: public class HeartPictureBox : PictureBox { protected override void OnPaint(PaintEventArgs pe) { using (System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath()) { path.AddBezier(this.Width >> 1, this.Height >> 2, this.Width * 1.25f, 0f, this.Width, this.Height * 0

问题 I have problem with Graphics.RotateTransfrom() with the following code : Dim newimage As Bitmap newimage = System.Drawing.Image.FromFile("C:\z.jpg") Dim gr As Graphics = Graphics.FromImage(newimage) Dim myFontLabels As New Font("Arial", 10) Dim myBrushLabels As New SolidBrush(Color.Black) Dim a As String '# last 2 number are X and Y coords. gr.DrawString(MaskedTextBox2.Text * 1000 + 250, myFontLabels, myBrushLabels, 1146, 240) gr.DrawString(MaskedTextBox2.Text * 1000, myFontLabels,

问题 I need load XNA.Texture2D to PictureBox. i've tried this: http://www.gamedev.net/community/forums/viewreply.asp?ID=3224621 but it doesn't work. Any suggestions? 回答1: You should be able to use that method, but make sure that your XNA Texture2D is created with a format of 32bbpARGB. Any other format will prevent that method from working directly. 回答2: Easier way to do it is save the Texture2D using Texture2D.SaveAsPng or Texture2D.SaveAsJpeg to a memory stream and the open the virtual file

问题 I have a form with OpenFileDialog for selecting image and showing it in pictureBox . Until the form is open the user can open and then save the opened image as many times as he wants. What I want to do is, after each new selection-save, to delete the previously saved image if there is such. The problem is that as I implemented the code now I am able to delete the image the first time, if I keep on saving images with the currently open form I get an error that the resource is being used. What

问题 I'm currently trying to simplify a tool that we use at work. For this I would like to use the drag and drop method. The tool is basically like building a tower using three different kind of blocks. At the top there are the three images of the different blocks below is a flow-layout-panel. The goal is to drag in a desired order the blocks into the flow-layout-panel. Here is a quick image that would represent the start position. (Just to be clear.) This for me is the tricky part. I only used

问题 An exception is thrown in a user control based on a picture box, causing it to show the typical error image (red X). Since the GUI thread caught and handled the exception itself, I cannot easily find out where the exception occurred and debug. I'm currently wrapping the whole OnPaint code in a try-catch, and was able to debug the code, but I found it quite tedious so I wondered if there is a way to break into debugger from a GUI thread exception. 回答1: It already works this way by default.
