Wrong DLLCall Return - problems with PCWSTR

Recommended Posts

Trolleule

Hey peoplez,

i am tyring to run this function properly: http://msdn.microsoft.com/en-us/library/windows/desktop/hh824745.aspx

On success, DLLCall returns "S_OK" -> 0

That's returned properly. Also

A pointer to the address of an array of DismMountedImageInfo Structure objects

and

The number of DismMountedImageInfo structures that are returned.

The number of mounted images is returned properly too. But the returned struct is wrong. I got following output:

0x0011CDC0

0x03AB09A0

0

0

0

$Return[2] have to be 3 (ImageIndex). I mounted an image with the DismMountImage Function...that works fine. So the entire struct i created must be wrong. :(

Can someone help me please!
