I looked up in the Internet, but there are only ways to show it when u have a real file and if it is not embedded in the resources.
推荐答案
从这里资源修改//是:字节[]在调用可变资源
// from resources modification here is : byte[] variable resource in the call
//由伊万Genesse修改的类
// modified class by Yvan Genesse
public class AdvancedCursorsFromEmbededResources
{
// modified by Yvan Genesse November 29 2010
// C# example tested in MS Visual Studio 2010 Ultimate version
// University Student in E-Business @ Laurentian University
// in your form code
/*
try
{
// from file
//this.Cursor = AdvancedCursors.Create(Path.Combine(Application.StartupPath, "flower_anim.ani"));
// from resouces modification here is : byte[] resource in the call
byte[] Embeded_Cursor_Resource = Properties.Resources.flower_anim; // the animate cursor desired
this.Cursor = AdvancedCursorsFromEmbededResources.Create(Embeded_Cursor_Resource);
// or this way also works
this.Cursor = AdvancedCursorsFromEmbededResources.Create(Properties.Resources.flower_anim);
}
catch (Exception err)
{
MessageBox.Show(err.Message);
}
*/
[DllImport("user32.dll")]
static extern IntPtr CreateIconFromResource(byte[] presbits, uint dwResSize, bool fIcon, uint dwVer);
// modification here is : byte[] resource in the call
public static Cursor Create( byte[] resource)
{
IntPtr myNew_Animated_hCursor;
//byte[] resource = Properties.Resources.flower_anim;
myNew_Animated_hCursor = CreateIconFromResource(resource, (uint)resource.Length, false, 0x00030000);
if (!IntPtr.Zero.Equals(hCursor))
{
// all is good
return new Cursor(myNew_Animated_hCursor);
}
else
{ // resource wrong type or memory error occurred
// normally this resource exists since you had to put Properties.Resources. and a resource would appear and you selected it
// the animate cursor desired is the error generator since this call is not required for simple cursors
throw new ApplicationException("Could not create cursor from Embedded resource ");
}
}
}
