how to work with image component ?

[Abdel Hamid]

Hello guys,
am trying to develop a simple application that changes the desktop wallpaper 
the only problem for me , how to use Image component ?
first step finished : using openfiledialog to load ("jpg files") ! (i used " Create File " to get the handle of the file opened as a first step)
second step not finished yet (loading the image to Image component) so the user can view the chosen image 
third step : Pressing the button to chage the wallpaper (finished) , i used SystemParametersInfo
now what are the functions used to deal with (Image) component ! am stuck at this stage  :(
PS : am working on both RadASM and WinAsm
thank you in advance  :t

Code Select Expand

second step not finished yet (loading the image to Image component) so the user can view the chosen image 

The best way to preview the image, is use gdi or gdi++ and blit it to your dialog (bitblt)

Gdi++ or Gdi

What is your problem correctly?
Your video draw the image on dialog ok,
and set the wallpaper need you SystemParametersInfo correct.

SystemParametersInfo,SPI_SETDESKWALLPAPER, 0, chr$ ("C:\wallpaper.jpg"), SPIF_UPDATEINIFILE

Hi mabdelouahab,

Thanks for your example. It's better than mine changing the wallpaper with COM.
