A DWORD is a DWORD is a ... oh f***!

[jj2007]

keep it simple, keep it consistent and spare yourself the complexity of endlessly chasing minor byte savings.

I agree. But there is a conflict between simplicity and the 100+ types used by the C/C++ brigade that needs to be addressed. In my tests, I could almost use Windows.inc "as is" for 64-bit builds - only 3 items need to be changed. That would make life simple, if we could double-use the main Masm32 includes...

I've just uploaded a new version, fixing minor glitches. Below the source of a windows GUI application; this is what you get in RichMasm with File/New Masm source. It builds with ML, ML64, AsmC, JWasm and HJWasm, as 32- and 64-bit code.

"If DWORD is typedef to unsigned long, then its length varies based on CPU type, not necessarily 32bit." ::)

In addition to these 300+ types, there are a few more that you absolutely need for happy coding ("The New Data Types"):

3 INT32 32-bit signed integer

13 INT_PTR Signed integer type for pointer precision.
14 LONG_PTR Signed long type for pointer precision.
15 SIZE_T The maximum number of bytes to which a pointer can refer. Use for a count that must span the full range of a pointer.
16 SSIZE_T Signed SIZE_T.
17 UHALF_PTR Unsigned HALF_PTR.
18 UINT_PTR Unsigned INT_PTR.
19 ULONG_PTR Unsigned LONG_PTR.
20 POINTER_32 A 32-bit pointer. On 32-bit Windows, this is a native pointer. On 64-bit Windows, this is a truncated 64-bit pointer.
21 POINTER_64 A 64-bit pointer. On 64-bit Windows, this is a native pointer. On 32-bit Windows, this is a sign-extended 32-bit pointer.

Hello sir jj2007
have found this link,  have a definition to double. Shows that unsigned long it's a dword.

Google says Adobe Flash has a different business model:

Today, more than 90% of Flash on the web loads behind the scenes to support things like page analytics. This kind of Flash slows you down

[raymond]

My approach: simply don't use these for your own work. It's an awful lot easier to go back to the good old days, and just "call" (or even "jmp"), and pass arguments any convenient way.

SOF: Determining 32 vs 64 bit in C++ 

Also nice: A Collection of Examples of 64-bit Errors in Real Programs

Our company OOO "Program Verification Systems" develops a special static analyzer, Viva64, which detects 64-bit errors in the code of C/C++ applications. During this development process, we constantly enlarge our collection of examples of 64-bit defects, so we decided to gather the most interesting ones in this article.

From the same authors: 20 issues of porting C++ code to the 64-bit platform

This article describes the process of porting a 32-bit application to 64-bit systems. The article is written for programmers who use C++ but it may also be useful for all who face the problem of porting applications onto other platforms. The authors of the article are experts in the field of porting applications to 64-bit systems

Hallo,

to make it convenient, I installed msdn locally, and then I add favorites ... The following picture shows how it looks .. I copied the Help Viewer in a separate folder, exactly the same as the copy of the msdn database. On this page you can find the document - Help Viewer Administrator Guide - https://msdn.microsoft.com/en-us/library/hh492077.aspx  Start Help Viewer autonomously through a shortcut so far without success, we need more option. If you make a start bat file, then you can not run the Help Viewer always through Visual Studio ... I think it very comfortable.

PDF with all types of data can be downloaded here - https://msdn.microsoft.com/en-us/library/cc230273.aspx or direct link https://winprotocoldoc.blob.core.windows.net/productionwindowsarchives/MS-DTYP/[MS-DTYP].pdf

Addition: "C:\masm32\jWasm\Microsoft Help Viewer\v2.2\HlpViewer.exe" /catalogName VisualStudio14 /helpQuery  "method=f1&query=masm" With this code for the shortcut Help Viewer can be launched without an assistant visual studio.

I use the VS help, see screenshot below. Is that a lot different? How do you get context-sensitive help, i.e. user has selected CreateWindowEx and hits F1 or selects menu as shown in screenshot below? Is that what you mean with "favorites"? Your solution with C:\Program Files\Microsoft Help Viewer\v1.0\HlpViewer.exe launches the viewer but it pretends that there is no content installed ::)

Your solution with C:\Program Files\Microsoft Help Viewer\v1.0\HlpViewer.exe launches the viewer but it pretends that there is no content installed ::)

Hallo,

the favorites list is on the left side in the picture, there is different information about the types and macros for assembler, and other information regarding the features of the assembler.

"C:\masm32\jWasm\Microsoft Help Viewer\v2.2\HlpViewer.exe" /catalogName VisualStudio14 /helpQuery  "method=f1&query=masm"

The lines above are responsible for finding specific information - "method=f1&query=masm", where the word "masm" search request, /catalogName VisualStudio14 indicates the version of the studio and the version of the catalog.
This message goes out through the launch of a shortcut? Directory address is prescribed in the system, the path can be seen in the tab "Manage Content". All these lines are added to the shortcut properties in the line "Target".
Your path will be - "C:\Program Files\Microsoft Help Viewer\v1.0\HlpViewer.exe" /catalogName VisualStudio10 /helpQuery  "method=f1&query=CreateWindowsEx"

The second solution may be the "C:\masm32\jWasm\Microsoft Help Viewer\v2.2\HlpViewer.exe" /catalogName VisualStudio14 /helpQuery method=f1&query=msdnstart /locale en-US /launchingApp Microsoft,VisualStudio,14.0

Your solution is also very cool! In the RadAsm 2.2 this function is unfortunately not implemented.

Visual Studio 2010

Visual Studio 2010 ships with Help Viewer 1.x. Help Viewer 1.x supports a custom ms-xhelp:/// protocol that you can use anywhere you can use an http:// url to link to the f1 keyword you created.

Here's an example ms-xhelp:/// uri you can use in a shortcut or as a command line from your application:

ms-xhelp:///?method=f1&query=InnovasysDocsStartPage&product=VS&productversion=100&format=html&locale=EN-US

Maybe directory error occurs because versions of Assistant?

[jj2007]

The second solution may be the "C:\masm32\jWasm\Microsoft Help Viewer\v2.2\HlpViewer.exe" /catalogName VisualStudio14 /helpQuery method=f1&query=msdnstart /locale en-US /launchingApp Microsoft,VisualStudio,14.0

No luck, it just complains that there is no content installed :(

Your solution is also very cool!

Thanks, I use it quite a lot

Back to topic: A DWORD is... here are a few "conversions" between DWORDs and other sizes:

Code Select Expand

lea rcx, [rax + rdx + 123h] ; 8->8
lea ecx, [rax + rdx + 123h] ; 8->4
lea rcx, [eax + edx + 123h] ; 4->8

mov rcx, rax ; 8->8
lea rcx, [eax] ; 4->8
movzx rcx, ax ; 2->8
movzx rcx, al ; 1->8

mov rax, 8765432187654321h ; a negative number
mov eax, eax ; rax=87654321h

mov rax, 8765432187654321h
cdqe      ; rax=0FFFFFFFF87654321h
