c# - Change Desktop Wallpaper using a Jpeg file -

-

I am trying to write a simple program to replace my desktop wallpaper. I am using a downloaded JPEG file and I would like to convert it to code. The problem is that bitmap needs to display 24 bits. How do I do this? thank you in advanced. Public class ChangeWallpaper {[DllImport ("user32.dll", Charset = Charset.auto)] Stable extern int system ParametersInfo (int uAction, int uParam, string lpvParam, int fuWinIni); Public Stable Zero Main () {bitmap wallbm = new bitmap ("pic.jpg"); Wallbm.Save ("pic.bmp"); SystemParametersInfo (20, 0, "pic.bmp", 0x01 | 0x02); }}

I could not work for a clone for some reason. I was able to work with trial and error using the following code: 

  public class ChangeWallpaper {[DllImport ("user32.dll", chartset = charset.auto)] steady extern int System ParametersInfo (IntuAuction, Intuperateum, String LPVPerm, Int FuWinini); Public Stable Zero Main () {bitmap BM = new bitmap (Image.FromFile ("pic.jpg")); BM. Save ("pic.bmp", imageform.bmp); SystemParametersInfo (20, 0, "pic.bmp", 0x01 | 0x02); }}

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
