With firewall.h, I obtain the methods. According to what I have read, I can refer to them through offsets.

   /* INetFwRule methods */
   HRESULT (STDMETHODCALLTYPE *get_Name)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_Name)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_Description)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_Description)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_ApplicationName)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_ApplicationName)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_serviceName)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_serviceName)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_Protocol)(INetFwRule *This,LONG*);
   HRESULT (STDMETHODCALLTYPE *put_Protocol)(INetFwRule *This,LONG);
   HRESULT (STDMETHODCALLTYPE *get_LocalPorts)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_LocalPorts)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_RemotePorts)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_RemotePorts)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_LocalAddresses)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_LocalAddresses)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_RemoteAddresses)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_RemoteAddresses)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_IcmpTypesAndCodes)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_IcmpTypesAndCodes)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_Direction)(INetFwRule *This,enum NET_FW_RULE_DIRECTION_*);
   HRESULT (STDMETHODCALLTYPE *put_Direction)(INetFwRule *This,enum NET_FW_RULE_DIRECTION_);
   HRESULT (STDMETHODCALLTYPE *get_Interfaces)(INetFwRule *This,VARIANT*);
   HRESULT (STDMETHODCALLTYPE *put_Interfaces)(INetFwRule *This,VARIANT);
   HRESULT (STDMETHODCALLTYPE *get_InterfaceTypes)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_InterfaceTypes)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_Enabled)(INetFwRule *This,VARIANT_BOOL*);
   HRESULT (STDMETHODCALLTYPE *put_Enabled)(INetFwRule *This,VARIANT_BOOL);
   HRESULT (STDMETHODCALLTYPE *get_Grouping)(INetFwRule *This,BSTR*);
   HRESULT (STDMETHODCALLTYPE *put_Grouping)(INetFwRule *This,BSTR);
   HRESULT (STDMETHODCALLTYPE *get_Profiles)(INetFwRule *This,LONG*);
   HRESULT (STDMETHODCALLTYPE *put_Profiles)(INetFwRule *This,LONG);
   HRESULT (STDMETHODCALLTYPE *get_EdgeTraversal)(INetFwRule *This,VARIANT_BOOL*);
   HRESULT (STDMETHODCALLTYPE *put_EdgeTraversal)(INetFwRule *This,VARIANT_BOOL);
   HRESULT (STDMETHODCALLTYPE *get_Action)(INetFwRule *This,enum NET_FW_ACTION_*);
   HRESULT (STDMETHODCALLTYPE *put_Action)(INetFwRule *This,enum NET_FW_ACTION_);

If I want to load a value into the put_name property, I need to find its offset. From what I have seen, this is calculated by enumerating each of the previously mentioned properties and multiplying by 4 if it's a 32-bit application or by 8 if it's a 64-bit application. In my case, I am developing the application with MASM32, so I multiply by 4.

get_Name - index 0
put_Name - index 1 (offset 1 * 4 = 4 bytes or 0x04)
get_Description - index 2
put_Description - index 3 (offset 3 * 4 = 12 bytes or 0x0C)

16 bit DOS Programming / Re: Bouncing Square Clipping

Last post by daydreamer - June 13, 2024, 12:17:13 AM

I agree with japhet 
But like to add, drawing or loading in initialize program sprite map in memory for moving objects simple to copy to screen
More advanced tiles for background objects combined with sprites if any sprites in front of tile before copying
Only need to update the tiles and sprites that changes on screen

MASM64 SDK / Re: cmd_tail

Last post by HSE - June 12, 2024, 11:59:09 PM

Does len take into account the zero terminator?

Fantastic Sinsi. That it's the point.

Then must be:

Code Select Expand

    mov r12, rvcall(GetCommandLine)
    mov r13, len(r12)
    add r13, 1
    mov r14, alloc(r13)

The Workshop / Re: Echo value of offset

Last post by TimoVJL - June 12, 2024, 11:32:00 PM

Problems come when using on bounds...

Bounds? as in array bound checking?
Just curious.

As bounds of assembler abilities. A default solution is the immediate value, but i need to get that from the expression of offsets.

masm isn't high level language, just with macro language additions.

MASM64 SDK / Re: cmd_tail

The proper solution would clearly be to fix the library source, i.e. cmd_tail.asm

16 bit DOS Programming / Re: Bouncing Square Clipping

Reading up on the subject, to get a smooth moving object, it looks like the only way is to go unchained mode on 320 x 200 or mode X 320 x 240 and do page flipping.

Not necessarily. However, you shouldn't render your items directly in video memory. A better approach is to render the screen contents in a memory buffer , wait for vertical retrace and finally do a quick copy from your buffer to video memory.

Also, to draw a square by using line drawing code isn't very fast, btw.

Attached your modified sample, using a buffer.
