LoadImage and OEM icons

[Shantanu Gadgil]

Hi,
Any idea why this would return NULL???

Code Select Expand

invoke LoadImage, 0, OIC_SAMPLE, IMAGE_ICON, 32, 32, LR_DEFAULTCOLOR
Same problem for any of the OIC_xxx

This works fine:

Code Select Expand

invoke LoadIcon, 0, IDI_APPLICATION

What does GetLastError return?

I cannot routinely find the reference for a constant like OIC_SAMPLE on MSDN online. Where does this come from ?

[sinsi]

Looks like the last parameter needs LR_SHARED

Code Select Expand

invoke LoadImage, 0, OIC_SAMPLE, IMAGE_ICON, 32, 32, LR_DEFAULTCOLOR OR LR_SHARED

Hutch, OIC_* are defined in winuser.h

Hello sinsi,
It works with LR_SHARED!!!  :U :U

Another problem though...no matter what dimensions I give (16x16, 48x48) it is giving me handle to a 32x32 icon!!!  :'( :'(

Any tips?

Maybe an OEM icon only comes in one size?

cxDesired
   [in] Specifies the width, in pixels, of the icon or cursor. If this parameter is zero and the fuLoad parameter is LR_DEFAULTSIZE, the function
         uses the SM_CXICON or SM_CXCURSOR system metric value to set the width. If this parameter is zero and LR_DEFAULTSIZE is not used,
         the function uses the actual resource width.

Notice that the parameter is called cxDesired, your "desired" width. Windows seems to have a "close is good enough" mentality when
it comes to icons...

To sinsi,
Oh well...what to do! Thanks for the previous tip!

No worries mate  :U

If you do find out how to get other sizes, let us know eh?
Good luck!
