1. Help with Windows API ImageList_LoadImage needed
- Posted by 1evan at sbcglobal.net

Using the following definitions, when I call ImageList_LoadImage, it
always gives me "Image not loaded."
Any ideas why? Do I not have something defined correctly? MyIcon.ico
is a 16x16 icon.
ImageList_LoadImage = link_c_func(comctl, "ImageList_LoadImage",
{C_INT,C_POINTER,C_INT,C_INT,C_UINT,C_UINT,C_UINT},C_INT)
CLR_DEFAULT = #FF000000
LR_LOADFROMFILE = #0010
Image = allocate_string("MyIcon.ico")
if not
c_func(ImageList_LoadImage,{NULL,Image,16,1,CLR_DEFAULT,1,LR_LOADFROMFILE})
then
puts(1,"Image not loaded" & '\n')
end if

Im not sure what you're doing here but Ive always loaded my ImageList like so:
hImageList = c_func(xImageList_Create,{16,16,ILC_COLOR16,2,10})
hBitmap = LoadImage("image.bmp", IMAGE_BITMAP)
junk = c_func(xImageList_Add,{hImageList,hBitmap,NULL})
c_proc(xDeleteObject, {hBitmap})
using standard LoadImage instead of ImageList_LoadImage
This has always worked for me.
Take a look at my EFFM project in the RDS archive...

Treeview.ew loads a user created imagelist from file
Hope this will help..

Maybe "MyIcon.ico" is not in the current directory. You don't specify a
path to it in the allocate_string() so it would be looking for it in the
current directory.

Thanks, I already decided that LoadImage was the way to go. Not really
sure of what I'm doing either 
.
Just trying to load some images in an Image List and put those images on
tool bar buttons.
I seem to be alright in creating the Image List now. Now if I could
just get the buttons on the tool bar!

hi : This parameter can be NULL if you are loading an image from a file
(which I am).
lpbmp: If the /uFlags/ parameter includes LR_LOADFROMFILE (which it
does), /lpbmp/ is the address of
a null-terminated string that names the file containing the
image to load. (which it is).
If /hi/ is NULL and LR_LOADFROMFILE is not specified (but it
is), the low-order
word of this parameter must be the identifier of an OEM image
to load.
I believe Robert Craig wrote that the C_ types were identical in how
they were handled, except for C_DOUBLE. COLORREF might need to be a
double, I'm not sure.
Anyway, I decided to go with LoadImage instead. Thanks for your advice,
though.

No, it's in the current directory. I checked by opening it in the
program, seeing if I got a handle for it, then closed it.
I went to LoadImage and that seems to be working for me.
Thanks for taking the time to respond.
