Heres my problem, Im trying to get the path/filename to the icon from  an .exe file. Can any one modify the following bit of code to do this (since it doesnt work at the moment).

SHFILEINFO shfi;
if(SHGetFileInfo("c:\\windows\\regedit.exe",0,&shfi,sizeof(SHFILEINFO),SHGFI_ICONLOCATION))
{
CString me = (char*)shfi.szDisplayName;
TRACE("Succeded getting icon path  
from .exe*%s*\n",me);
}
else
{
TRACE("FAILED\n");
}

Thanks in advance

SHGFI_ICONLOCATION only gets the display name of the application as it appears from on the desktop. Can you make it clear why would you like to get the filename of the icon ?

I have a program which converts a filename of an icon into a bitmap. I was hoping to use SHGetFileInfo (SHGFI_ICONLOCATION) because according to the documentation it retrieves and I quote "The name of the file that contains the icon representing the file. The name is copied to the szDisplayName member of the structure specified by psfi".

That is why I would like to be able to get hold of a programs, associated icon's filename.

Alternatively could someone tell me how to convert a HICON to a CBitmap.
Thanks again
Ian

to convert HICON into CBitmap :

Create a memory DC, create a bitmap, select this bitmap in DC,
call DrawIcon-function, than you'll have in this created bitmap the icon's image.

Ok I dont know that much about MFC/windows calls
Ive tried papirus suggestion and nothing happens what am I doing wrong.


HICON hGen32Icon;
SHFILEINFO shfi;
CBitmap *ian = new CBitmap;
HDC ianDC=::CreateCompatibleDC(NULL);

if(SHGetFileInfo("c:\\windows\\regedit.exe",0,&shfi,sizeof(SHFILEINFO),SHGFI_ICON))
{
      hGen32Icon = shfi.hIcon;
TRACE("1Succeded getting icon from .exe\n");
      DrawIcon(ianDC,0,0,hGen32Icon);
      GetMenu()->SetMenuItemBitmaps( IDM_ONE, MF_ENABLED,ian,NULL);

}

try this :

CBitmap Bmp ;
CDC MemDC  ;

MemDC.CreateCompatibleDC(NULL) ;
Bmp.CreateCompatibleBitmap(&MemDC,32,32) ;
MemDC.SelectObject(&Bmp) ;
::DrawIcon(MemDC.m_hDC,0,0,hIcon) ;

....

CBitmap Bmp ;
CDC MemDC ;
CDC *pWndDC = AfxGetMainWnd()->GetDC() ;
if (pWndDC)
{
      MemDC.CreateCompatibleDC(pWndDC) ;
      Bmp.CreateCompatibleBitmap(&pWndDC,32,32) ;
      MemDC.SelectObject(&Bmp) ;
      ::DrawIcon(MemDC.m_hDC,0,0,hIcon) ;
      AfxGetMainWnd()->ReleaseDC(pWndDC) ;
}
