Images in Listview

[Grincheux]

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,PBrennick

causation:
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.

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

there are the "Res\\ToolBar.bmp","Res\\BO1616_01.bmp" in his original zip file.

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
