If each image is the same size, then create an image that has all of the images in one strip.

Place a TImageLIst on your form and set the height and width property that each individual
image is.  For example, if you have a strip that is 64 x 16 and each image
is 16 x 16, the strip contains 4 images, each of which is 16 wide and 16
tall, so set the imagelist height and width to 16.

 Next include the resource file in the appropriate unit, i.e. {$R
MYIMGS.RES}

Then, in your code,  Load the images in the imagelist as follows.

  MyImageList.ResourceLoad(rtBitmap, 'CLASSIMAGES', clBlue);
  if   MyImageList.Count=0 then
    MessageDlg('Could not load   My Image List',mtError,[mbOK],0);

Note: clBlue is the background color to be used for transparency purposes .


Now you have a TImageList with your images,

You can step through the imageList and display the images 1 at a time



 step through the images int he list, and display them in a TImage component

 for I:= 0 to ImageList.Count-1 do
 begin
  MyImageList.GetBitmap(I, MyImage.Picture.Bitmap)
  //maybe add somedelay here using TTimer, thread, or even just the Sleep function
 end;

what means 'CLASSIMAGES'
and my images are in dll file.
i will use Ttimer to control them.

shaneholmesCommented:
Well, you never said anything about a DLL....

Anyway, they are in a resource file compiled in the DLL right?

(You already of the code to load the DLL right? OR No

If so, you can use the same code.


change

MyImageList.ResourceLoad(rtBitmap, 'CLASSIMAGES', clBlue);

to

MyImageListResInstLoad(<HANDLE of DLL goes here>, rtBitmap, CLASSIMAGES, clBlue)

CLASSIMAGES is an example name of what you called your images in the Resource file

You should have one image like i described above, called CLASSIMAGES or whatever you want to call it.

i have 33 images(bitmap) and still i cant understand u.
i do this code but no response:-


mydll := LoadLibrary('resdll.dll');
  if mydll=0 then
     raise Exception.Create('Cannont load resource library. Please check if RESONLY.DLL is in the application''s folder');

  imagelist2.ResInstLoad(mydll,rtBitmap,'1', clBlue);

Are all the images the same size? If so what is there size?

sal1150Author Commented:
yes all with same size.
125x125

shaneholmesCommented:
Ahhh, thats a good size image. They only way you can load the TIMageList with a ResInstLoad, is if you combine all the images into one image (in this case the size would then be 4125 X 125). IN your case, you would name it '1' and recompile the resource into your DLL.

Set your TImageList & TImage height & Widths to 125

 mydll := LoadLibrary('resdll.dll');
  if mydll=0 then
     raise Exception.Create('Cannont load resource library. Please check if RESONLY.DLL is in the application''s folder')
  else
  imagelist2.ResInstLoad(mydll,rtBitmap,'1', clBlue);

WHen the ImageList loads the 1 image in using ResInstLoad, it will automatically split the picture up into its 125 X 125 parts.

in case of 'ResInstLoad' is it used 'GetBitmap' or 'GetInstRes'?

shaneholmesCommented:

 first, make sure your imagelist is getting the image from the DLL


 mydll := LoadLibrary('resdll.dll');
  if mydll=0 then
     raise Exception.Create('Cannont load resource library. Please check if RESONLY.DLL is in the application''s folder')
  else
  begin
   imagelist2.ResInstLoad(mydll,rtBitmap,'1', clBlue);
   ShowMessage(IntToSTr(imagelist2.Count));
 end;

GetInstRes loads a particular bmp from the resource file into the imagageList.

GetBitmap gets a particular bitmap from an index in the imagelist and places it in the variable
example - ImageList2.GetBitmap(0, bmp); gets the first image and assignes it to bmp

shaneholmesCommented:
ok, if your using

 imagelist2.ResInstLoad(mydll,rtBitmap,'1', clBlue);

that means you have a resource file with an image in there called '1'.

Not with an ID of 1, a name called '1' (a string name)

Is this correct?

if your app is not huge, i would entertain the thought of you zipping it up and mailing it to me and i would take a look at it for you.

you would also have to include the image and the DLL source
