In the previous article, we mentioned how to implement image dragging and control array in picturebox in VB.net. As required by the project, the image contains the names of various sites. To achieve this, click the corresponding name to enter the site and view the corresponding information. I chose to put a series of labels on the image, and then click the label to enter the corresponding site. In this way, I encountered a problem. When dragging the i

Method 1: The simple method is to change the borderstyle style of the picturebox control. CurrentSelectPicBox. BorderStyle = BorderStyle. Fixed3D;CurrentSelectPicBox. Refresh (); // force the control to redraw Method 2 Adding a rectangle to the picturebox control makes this method slow in the program.

Method One: The easy way is to change the BorderStyle style of the PictureBox control Currentselectpicbox.borderstyle = Borderstyle.fixed3d;Currentselectpicbox.refresh ()//force control to repaint Method Two Add a rectangle to the PictureBox control but this method reacts slowly in the program. How to add a rectangle box:Graphics Pictureborder = Currentselectpicbox.creategraphics ();Pen pen = new Pen (

Controls | arrays In the previous article, you mentioned the implementation of PictureBox in vb.net, as well as the control array. Because the project needs, what I want to realize is that the picture has the name of each site, I want to realize click the corresponding name, go to the site, view the corresponding information. I take a series of labels on the picture, and then click on the label, go to the appropriate site, so that I encountered a prob

Today to do a photo program, the camera SDK everything is done, just to display the image and save the photo step card for half a day.The reason is that the preview image uses PictureBox and the image file is loaded in the following way: Pictureboxphoto.image = Image.FromFile (filepath);However, this will cause the image file to remain in the occupied state, once the photo completion needs to overwrite the source map, because the file operation is no
