Print Page - Images in Listview

Title: Images in Listview
Post by: Grincheux on November 23, 2006, 12:47:43 PM

I am trying to write a small ACDSee software and meet some problems with image into a listview.

When Windows sends LVN_GETDISPINFO I load the picture and draw it into an imagelist.

On the screen I temporarily see the image and it is replaced by a white image !

I don't understand. And MSDN does not say anything very interesting on using images into listview.

I join my project expecting some help :dance:.

Thanks

I could not build the project to test your problem because you did not include the res folder in your zip.

Hey,Grincheux
.

Code Select

DATA?
	Pointers    dd OBJECTS_COUNT dup(?)
.CODE
	;-------- VirtualAlloc --------
	mov     esi, OBJECTS_COUNT
@@:
	invoke  VirtualAlloc, 0, OBJECT_SIZE, MEM_COMMIT, PAGE_READWRITE
	dec     esi
	mov     [Pointers + esi*4], eax
	jnz     @B
@@:
	mov     eax, [Pointers + esi*4]
	invoke  VirtualFree, eax, 0, MEM_RELEASE
	inc     esi
	cmp     esi, OBJECTS_COUNT
	jne     @B
;==============================================================================

Quotecausation:
1. made the windows msg to be mess
2. the memorys allocating have some problems. one JPG file should be a piece of memory
;==============================================================================

maybe the code works ok while a directory has one JPG file.

Is that a fact?

Then how do you explain this and the errors it creates when the bitmaps do not exist? I prefer to use the toolbar.

Code Select


IDB_BARREOUTILS         BITMAP                  "Res\\ToolBar.bmp"
IDB_BO16_01             BITMAP                  "Res\\BO1616_01.bmp"

This sounds a bit presumptous to me, but I just love your user name. :U

six_L,
Thanks,
So you are using them. You are confusing me. :dazzled:

Anyway, I guess my first download failed as it did not have that folder. The one I just got has it.

I'm outta, here, stay cool :8)

Hey. Any ideas on how to add images of different sizes either to an imagelist and a listview control? should i use ownerdraw? i'm making a resource viewer and i'm currently using shell32 and explorer.exe except some bitmaps are different in size from the others. i'd like to know what to do about this . If someone has answers feel free to reply.
Ty and bye.
best regards :U
