that function is one of a few that got left out of the kernel32.inc and krnl32p.inc files

probably the best solution is to....

1) update the kernel32.inc and kernl32p.inc files
2) create DEF files using Erol's INC2DEF.EXE
3) create new kernel32.lib and kernl32p.lib

EDIT: removed the "A" from the function names   :P

I have the newest masm pkg installed. Where would I find newer ones ?

I will learn how to make libs.

here you go, Andy - read through this thread...

http://www.masmforum.com/board/index.php?topic=18850.0

it has bits and pieces in the different posts, that all add up to a working method - lol

grab Erol's DEF2LIB.EXE   :t
it will actually make much smaller LIB's than the ones in the masm32 package

EDIT: this post describes the problem...

http://www.masmforum.com/board/index.php?topic=18850.msg159809#msg159809

it isn't really a "bug", per se,
but Hutch's INC2L.EXE program needs a little update to properly handle the new UNICODE include files

It helps to note in the .rc file, which version of MASM that was used for the project.

I have a backup of all my development versions for reuse to rebuilt code for a 'quick' update.

I had no rc file for this project.

I thought that maybe an include or library had changed, never occured that it might be caused by the new masm package.

Good idea, I will started including the version in my source.

another thing that may help
i installed masm32 v10, then renamed the folder to masm32_v10
then, i installed masm32 v11
by simply renaming the folders, i can switch between versions

masm32
masm32_v11

masm32_v10
masm32

I just install different versions on different drives
Well Microsoft, here's another nice mess you've gotten us into.

It is a good habit to get into.

In the "StringFileInfo" block, I leave notes to myself and to others who care to look.

Including a Copyright Notice.

I just rename the ext.  MASM32.V11.  I keep all these directories on the same drive.  So that the default program for .asm picks up in place on each version.

When I run my program, it does the following:

1. Says program is not running
2. Then it says program has been terminated
3. CLOSE THIS WINDOW window appears on the open programs bar
4. Neither of the 2 programs are stopped
5.
6.

When run in a debugger, it does this:
(I find it interesting to see such differences when run in a debugger.)

1. Both programs are terminated.
2. CLOSE THIS WINDOW window appears on the open programs bar
3. Both programs are terminated but watchdog.exe restarts itself ??
4.

Magnum...

Please explain why you want to terminate MsMpEng.exe ?...

AFAIK this is a component of Windows One Care (older), Windows Defender, Windows Forepoint Protection and Windows Security essentials application

Who's "watchdog.exe" is this as well ???

Please understand, we are programers that have had our programs misused in ways we had not intended.
