noob questions about uasm64 usage

[jimg]

After screwing around for several days trying to figure out how to set up my system to produce 64-bit programs using uasm and wininc, it occurred to me that maybe I didn't have to keep both 32 and 64 bit working.  Before jumping to conclusions based upon nebulous trial and error I thought I'd just ask.

(Assuming I'm working on a computer with 64-bit windows running,) If one uses uasm64, can it also produce 32bit programs, or do I also need to keep uasm32 for 32-bit only programs?  If 64 will produce 32bit programs, are there any special s-field options that need to be different?  (Currently I normally use  /nologo /c /coff /Cp /Fl /Sn /Sg)

Also, it this the place to ask such questions, or would the uasm people prefer it be in the generic "64 bit assembler" subforum?

\masm32\bin\UAsm64 -Zp8 -win64 somesource.asm should do the job. Probably the -Zp8 is no longer needed, but let's hear the experts on that ;)

And yes, on a 64-bit machine you need only UAsm64. It can generate 32-bit code.

uasm32 and uasm64 can both produce 32bit or 64bit output formats. The only reason both exist is so that you can run it at all on a 32bit system. Additionally uasm32 is built with XP compatibility toolset. :)

What does this flag mean in uasm -Fs[=<file_name>] - Write symbolic debug info? How can it be used?

[johnsa]

It writes out the debugging symbols into a simple format that easy for you to view or use in other debugging applications. It was added mainly as a way to provide symbolic debugging when generating flat binary files. IE: for OS development etc. It's documented in the user guide.

How can I use Windows COM objects (such as IFileOperation)?
Do you have any sample in uasm?

A quick COM example :

OK, but where I can get value for CLSID_FileOperation ?

In you source are

Code Select Expand

sCLSID_IActiveDesktop       TEXTEQU <{075048700h,0EF1Fh,011D0h,{098h,088h,00h,060h,097h,0DEh,0ACh,0F9h}}>
sIID_IActiveDesktop         TEXTEQU <{0F490EB00h,01240h,011D1h,{098h,088h,00h,060h,097h,0DEh,0ACh,0F9h}}>

where same values for another COM ?

CLSID_FileOperation GuidFromString("3ad05575-8857-4850-9277-11b85bdb8e09")

(and Google is your friend)

Thank you jj2007!

COM is very hard technology.

Hi morgot,

You can check the file shlguid.inc coming with the asmc package :

https://github.com/nidud/asmc

Reading shlguid.inc :

Code Select Expand

DEFINE_GUID( CLSID_ActiveDesktop, 0x75048700, 0xEF1F, 0x11D0, 0x98, 0x88, 0x00, 0x60, 0x97, 0xDE, 0xAC, 0xF9);
DEFINE_GUID(IID_IActiveDesktop, 0xF490EB00, 0x1240, 0x11D1, 0x98, 0x88, 0x00, 0x60, 0x97, 0xDE, 0xAC, 0xF9);

COM is very hard technology.

The learning curve is a bit steep, right. However, the main problem is that there are so many functions available, and there is no central documentation where to find all those cryptic CLSID and IID values. Even the Visual Studio include files don't have CLSID_ActiveDesktop, for example. Once you have those for your project, it can be quite straightforward:

include \masm32\MasmBasic\MasmBasic.inc
  Init ; ## COM demo: open Internet Explorer ##
  invoke OleInitialize, NULL
  .if eax==S_OK
push Chr$("http://masm32.com/board/index.php?action=unread")
call MyBrowser
  .endif
  invoke OleUninitialize
  Exit
CLSID_IExplorer GuidFromString("0002DF01-0000-0000-C000-000000000046") ; either use quoted text syntax or...
IID_IWebBrowser2  GuidFromString({D30C1661-CDAF-11D0-8A3E-00C04FC9E26E}) ; ... paste copied registry key name
MyBrowser proc uses edi url
LOCAL vEmpty:VARIANT, hWin, WebInterface
  ClearLocals
  lea edi, WebInterface
  pInterface equ dword ptr [edi]
  invoke CoCreateInstance, addr CLSID_IExplorer, NULL, CLSCTX_LOCAL_SERVER, addr IID_IWebBrowser2, edi
  .if eax==S_OK
CoInvoke pInterface, IWebBrowserVtbl.put_StatusBar, VARIANT_FALSE ; OK, now configure the browser
CoInvoke pInterface, IWebBrowserVtbl.put_MenuBar, VARIANT_FALSE   ; false = no menu
CoInvoke pInterface, IWebBrowserVtbl.put_Visible, VARIANT_TRUE
CoInvoke pInterface, IWebBrowserVtbl.get_HWND, addr hWin
lea edx, vEmpty ; Navigate needs pointers to four empty VARIANTS
; Ole$(url): COM wants a BSTR, so the ANSI URL needs to be converted
CoInvoke pInterface, IWebBrowserVtbl.Navigate, Ole$(url), edx, edx, edx, edx
  .endif
  ret
MyBrowser endp
end start

Time to do something about that, for example static GUID/IIDs ?
We can always create a program to convert or lookup GUID/IID from uuid.lib.

My example in so hated C in this site ;)
One problem is that '_' before name in 32-bit files.

In martial arts there is a legend about a root style that is perfection. It is known as
The Sun Source (Assembly) and that all other martial art styles are derived from it (C,C++,etc).
Thus they are not perfection.

I do not hate C. It is much cleaner than all the others as well as been elegant.
