LoadLibrary

[ragdog]

Hi

I have a question to this api LoadLibrary
Map this a dll to the memory?

Can i use CreateFileMapping>> MapViewOfFile for use this dll with GetProcaddress?
Or can i use FindResource>>SizeofResource>>LoadResource>>LockResource?

Greets,

Hi ragdog,

The problem is that if you loade the DLL as binary data ( for example from resource ) , you have to do all the PE section initializations.

    Well,.... i have some questions too in a related subject matter. Is there a limit for resource opperations after a library is loaded? In this prog i'm attaching to this post, i load resources - essencially bitmaps, icons and cursors - from shell32.dll. Then i insert the images into a ListView control. The viewing is done throught a treeview control with the resource types and names. What happens is that if i insist a little on choosing a resource type and then another, the images all go away i don't know why. Everytime there a TVN_SELCHANGE msg the images are loaded and freed so i don't know what could be wrong. Someone take a peek into what i've done and see if you get where the problem is. Thanks guys, you're the best.
   Bye

   i'm not sure yet what to do with the picture. I feel you're giving me some hints but not really telling me whats wrong. Do you know what's wrong? Is this some sort of educational thingy?
   Well... thanks anyway.... i guess i must get my brains working.
   Bye and ty Ded

no - i don't know what the problem is
i only noticed that some icons are not displayed properly
i wasn't sure if you saw what i saw, as you may be using a different OS

    oh yeah... They're toolbar bitmaps. It seems you can use a single bitmap for toolbar. the bitmap is for ex. only 32 high but images*32 long. But i don't think that that's the problem. Well...
   .... thanks

   can we close a handle returned by findresource? It seems at seems at some point findresource fails and i cant load any more images.
   Thanks guys.

Terminating the application should release the handle returned by FindResource

[xandaz]

    What if i don't want to terminate the application? is there a specific finction to release that type of handle?
   Thanks.

Not sure but one of those functions could solve the problem : DestroyAcceleratorTable , DeleteObject , DestroyCursor , DestroyIcon , DestroyMenu

[xandaz]

   All things were destroyed after having been added to the imagelist. I think it's the find resource function that isn't working. Well... i think i'll pass this and construct all of the list views on application start and that's the end of it.
   Thanks.
