How can I make the focus move to the next control when the user presses the Enter key in a TextBox
Add a handler for your TextBox’s KeyDown event. (This assumes you set the AcceptsReturn property to False). Then in your KeyDown eventhandler, have code such as: [C#] if (e.KeyCode = Keys.Enter) SendKeys.Send(‘{TAB}’); [VB.NET] If e.KeyCode = Keys.Enter Then SendKeys.Send(‘{TAB}’) EndIf
How can I check if a certain resource is included in a assembly?
If a resource is not available in a assembly or in satellite assemblies you will get a message like this ‘Could not find any resources appropriate for the specified culture…’. You can open your assembly and any related satellite assemblies in ILDASM (tool that ships with the .NET framework). When your assembly is open in ILDASM take a look at the manifest file. This contains a list of the resources in your assembly. Usually such errors are the result of incorrect namespaces being used or from spelling errors.
I want to iterate through both files and folders in a given folder. Is this possible
Yes string[] contents = Directory.GetFileSystemEntries(‘folderName’); foreach(string s in contents) Console.WriteLine(s);
How do I capture a bitmap of my form
You can import the BitBlt API to handle this problem. Here is a solution offered by Simon Murrell and Lion Shi in the microsoft.public.dotnet.windows.forms newsgroup. The number used below, 13369376, is Int32 SRCCOPY = 0xCC0020; You can use Gdi32 dll. You can define the BitBlt method found within the Gdi32 dll with the code below. [System.Runtime.InteropServices.DllImportAttribute(‘gdi32.dll’)] private static extern bool BitBlt( ntPtr hdcDest, // handle to destination DC int nXDest, // x-coord of destination upper-left corner int nYDest, // y-coord of destination upper-left corner int nWidth, // width of destination rectangle int nHeight, // height of destination rectangle IntPtr hdcSrc, // handle to source DC int nXSrc, // x-coordinate of source upper-left corner int nYSrc, // y-coordinate of source upper-left corner System.Int32 dwRop // raster operation code ); And you can then use the copy below in a button click event to save the form to an image. Graphics g1 = this.CreateGraphics(); Image MyImage = new Bitmap(this.ClientRectangle.Width, this.ClientRectangle.Height, g1); Graphics g2 = Graphics.FromImage(MyImage); IntPtr dc1 = g1.GetHdc(); IntPtr dc2 = g2.GetHdc(); BitBlt(dc2, 0, 0, this.ClientRectangle.Width, this.ClientRectangle.Height, dc1, 0, 0, 13369376); g1.ReleaseHdc(dc1); g2.ReleaseHdc(dc2); MyImage.Save(@’c:\Captured.bmp’, ImageFormat.Bmp); You will need to use the System.Drawing.Imaging namespace. Here is VB code posted by Armin Zingler in the microsoft.public.dotnet.languages.vb newsgroup.
