i have 100 or so little images i need to load and i dont want to manually go through all of them (but i will if i have to) and i was hoping some way i could do it as a loop, because their names are all close of by one number (the next number) and i was wondering if someone had some newer ideas (i am in DBP) thanks a lot

if the images are named "image" with the image # at the end like:
image5.bmp then you can load multiple images like this:
(NOTE: change the '.bmp' in the code if you load different file types.)

+ Code Snippet

for a=1
image$="image"+str$(a)+".bmp"
load image image$, a
next a

NOTE: If your images are located in a different folder and you must specify a path to the files, then add the following line right before the 'load image' command:
image$="PATH TO FOLDER CONTAINING IMAGES"+image$
make sure you include a '' at the end of the path.

The right man in the wrong place can make all the difference in the world.

For that example to work, you need to know how many images there are to load. The line:

For A=1

won't work.

An alternative (and very similar) method would be:

+ Code Snippet

FinishedLoading = 0
A=0
Repeat
  Inc A
  Image$ = "Image"+str$(A)+".bmp"
  If File Exist(Image$)
    load image image$, A
  Else
    FinishedLoading = 1
  Endif
Until FinishedLoading = 1

This will load all images - regardless of how many - as long as they are named 'ImageNumber.bmp' and the numbers used are consecutive.

[Edit] Oops lol - half my code was Delphi. Now fixed!

If their little images it's better to put them into one graphic, load that, then grab each image individually. It takes a lot of work but in the long run it's easy to add new images and use them. Also it cuts down on the files which is always a plus for any project.

+ Code Snippet

` Make 100 images (this is where you just use "load image")
Image=1
for y=1 to 400 step 41
 for x=1 to 400 step 41
  ink rgb(rnd(255),rnd(255),rnd(255)),0
  box x,y,x+40,y+40
  ink rgb(255,255,255),0
  center text x+20,y+12,str$(Image)
  inc Image
 next x
next y

` Grab images
Image=1
for y=1 to 400 step 41
 for x=1 to 400 step 41
  get image Image,x,y,x+40,y+40,1
  inc Image
 next x
next y

` Paste images to the screen
cls
do
 paste image rnd(99)+1,rnd(640),rnd(480),1
loop
wait key

or if files not neatly numbered you could do something like:

+ Code Snippet

restore imgfiles
img=1
done=0
repeat
   read img$
   if img$="done"
      done=1
   else
      load image img$,img
      inc img
   endif
until done

imgfiles:
data "button1.png","icons/gold.bmp","menu/start.jpg","menu/quit.jpg","weapons/gun/colt45.png"
data "weapons/medly/axe.bmp","done"

The word "Gullible" cannot be found in any English Dictionary.
