Hi again : I need to convert this C structure to win32 asm : typedef struct { UINT uiImageWidth; UINT uiImageHeight; BOOL fLiveWindow; BOOL fOverlayWindow; BOOL fScale; POINT ptScroll; BOOL fUsingDefaultPalette; BOOL fAudioHardware; BOOL fCapFileExists; DWORD dwCurrentVideoFrame; DWORD dwCurrentVideoFramesDropped; DWORD dwCurrentWaveSamples; DWORD dwCurrentTimeElapsedMS; HPALETTE hPalCurrent; BOOL fCapturingNow; DWORD dwReturn; UINT wNumVideoAllocated; UINT wNumAudioAllocated; } CAPSTATUS; I tryed to do it as follows : CAPSTATUS STRUCT uiImageWidth DWORD ? uiImageHeight DWORD ? fLiveWindow DWORD ? fOverlayWindow DWORD ? fScalea DWORD ? ptScroll DWORD ? fUsingDefaultPalette DWORD ? fAudioHardware DWORD ? fCapFileExists DWORD ? dwCurrentVideoFrame DWORD ? dwCurrentVideoFramesDropped DWORD ? dwCurrentWaveSamples DWORD ? dwCurrentTimeElapsedMS DWORD ? hPalCurrent DWORD ? fCapturingNow DWORD ? dwReturn DWORD ? wNumVideoAllocated DWORD ? wNumAudioAllocated DWORD ? CAPSTATUS ENDS Is this correct? Where can I find something about conversions from C to asm? Thanks again. Sergio A.S. de Aguiar

Converting from C to asm

The h2inc.exe utility does a decent enough job converting simple structures like this. The only ref I found on C to asm types is on page 641 of the "Enviroment and Tools" manual for MASM (available here). It's not a complete list, but a decent enough start.

Converting from C to asm

Thanks for the answer, but I could'nt find the answer anywhere to my question. I just need to know if the structure above is right in asm, because I need to use it in my code. Specially the BOOL type - is it converted to DWORD in asm???? thanks : Sergio A.S. de Aguiar

Converting from C to asm

DWORD should be OK for bool type. I'm betting that ptScroll should be a POINT struct. CAPSTATUS STRUCT ... ptScroll POINT<> ... CAPSTATUS ENDS

for BYTE, CHAR, BOOL, BOOLEAN, 
                              	use    db


for DWORD, LARGE_INTEGER, LPXX, HANDLE        
    LPTSTR, LPARAM, UINT, INT, WNDPROC,
    HICON, HCURSOR, HBRUSH, LPCTSTR,
    HPALETTE, LONG, POINT
				use    dd

these are some translation i've used until now. Hope it help.

Converting from C to asm

to determine if you have proper conversion of such things as BOOL its a good idea to take a look at the windows.inc file. many of the common paramters are such as BOOL, UINT etc and see what they have been TYPEDEF to. here is a code snipet of the windows include of some of the paramaters TYPEDEF's:

BOOL            TYPEDEF DWORD
BOOLEAN         TYPEDEF BYTE
LPBYTE          TYPEDEF PTR BYTE
LPDWORD         TYPEDEF PTR DWORD
LPVOID          TYPEDEF PTR
LPCVOID         TYPEDEF PTR
LPSTR           TYPEDEF DWORD
LPCSTR          TYPEDEF DWORD
UINT            TYPEDEF DWORD
LONG            TYPEDEF DWORD
SCODE		     TYPEDEF LONG
WPARAM          TYPEDEF UINT
LPARAM          TYPEDEF DWORD
HANDLE          TYPEDEF DWORD
HWND            TYPEDEF DWORD
HGLOBAL         TYPEDEF DWORD
HGDIOBJ         TYPEDEF DWORD
HACCEL          TYPEDEF DWORD
HBITMAP         TYPEDEF DWORD
HBRUSH          TYPEDEF DWORD
HDC             TYPEDEF DWORD
HFONT           TYPEDEF DWORD
HICON           TYPEDEF DWORD
HMENU           TYPEDEF DWORD
HINSTANCE       TYPEDEF DWORD
HRGN            TYPEDEF DWORD
HRSRC           TYPEDEF DWORD
HCURSOR         TYPEDEF DWORD
COLORREF        TYPEDEF DWORD

in your conversion you can either use BOOL, or in your case DWORD they both mean the same thing. anon is correct when he wrote that the POINT is refereing to a STRUCT. ill explain using the souce code:

typedef struct {         
UINT uiImageWidth;              <--typical dword conversion
UINT uiImageHeight;                all the way till
BOOL fLiveWindow; 
BOOL fOverlayWindow; 
BOOL fScale; 
POINT ptScroll;                 <--here.. POINT is actually one
BOOL fUsingDefaultPalette;         of the more common structures
BOOL fAudioHardware;               you will encounter
BOOL fCapFileExists;              
DWORD dwCurrentVideoFrame; 
DWORD dwCurrentVideoFramesDropped;
DWORD dwCurrentWaveSamples; 
DWORD dwCurrentTimeElapsedMS; 
HPALETTE hPalCurrent;           <--dont get confused here this
BOOL fCapturingNow;                is just refering to a handle
DWORD dwReturn;                    and all handles are converted
UINT wNumVideoAllocated;           to DWORD
UINT wNumAudioAllocated; 
} CAPSTATUS; 

your final code should look like this:

CAPSTATUS STRUCT
   uiImageWidth                 DWORD ?
   uiImageHeight                DWORD ?
   fLiveWindow                  DWORD ?
   fOverlayWindow               DWORD ?
   fScalea                      DWORD ?
   ptScroll                     POINT <>  <--this is pointing
   fUsingDefaultPalette         DWORD ?      to a struct that
   fAudioHardware               DWORD ?      is already defined
   fCapFileExists               DWORD ?      for you in the 
   dwCurrentVideoFrame          DWORD ?      windows.inc
   dwCurrentVideoFramesDropped  DWORD ?
   dwCurrentWaveSamples         DWORD ?
   dwCurrentTimeElapsedMS       DWORD ?
   hPalCurrent                  DWORD ?
   fCapturingNow                DWORD ?
   dwReturn                     DWORD ?
   wNumVideoAllocated           DWORD ?
   wNumAudioAllocated           DWORD ?
CAPSTATUS ENDS 

the struct POINT looks like this in the windows.inc:

POINT STRUCT
  x  DWORD ?
  y  DWORD ?
POINT ENDS

hope this clears things up.

    Thanks to you all folks...
Now I can work on this structure on a very good way...

Thanks again :
