[linrad] problems getting inpout32.dll working with qt3 for windows

[Roger Rehr <comcast.net; w3sz@xxxxxxxxxxxxxxxx>]

Hello, All,

This is somewhat off topic, but not really as I am trying to make an 
external program to control my SM5BSZ WSE boxes in windows XP64.  They 
are nicely controlled via Linrad running under Windows XP64, but I am 
having trouble compiling and linking the windows version of QT3 to get 
my separate controller running.

QT3-designer compiles and runs, and my wsecontrol application compiles 
fine until I try to add the inpout32.dll to it.  When I add the lines:

HINSTANCE h_inpout;
h_inpout =    LoadLibrary("C:\inpout32\Win32\npout32.dll");

to my progam without adding an #include <windows.h> I of course get an 
error message on 'make' that LoadLibrary is undeclared.

When I added an #include <windows.h> I got for several hours today when 
running 'make' or 'mingw32-make' an error that
char* could not be converted to WCHAR* in HINSTANCE.  I am not able to 
take care of this by using an intermediate variable, nor by attempting 
a static_cast or dynamic_cast.

I played with the code by temporarily adding #install "windef.h" from 
linrad-02.37, and then began getting on 'make' and 'mingw32-make' reams 
of errors of the type:

C:/MinGW/bin/../lib/gcc/mingw32/3.4.2/../../../../include/wincon.h:64: 
error: `WCHAR' does not name a type
C:/MinGW/bin/../lib/gcc/mingw32/3.4.2/../../../../include/wincon.h:65:

C:/MinGW/bin/../lib/gcc/mingw32/3.4.2/../../../../include/wincon.h:90: 
error: `WORD' does not name a type

to the tune of 700K errors on a typical compile.

I modifed and then removed the reference to "windef.h" and set my code 
and #installs in my qt3 program back to what they were originally, and 
yet I still get the reams of errors as noted above, with both 'make' 
and 'mingw32-make'.  I can't get back to the original single error 
regarding char* vs WCHAR* types.  [And even if I could, I would still 
have the original problem].

I have tried both the 'stable' 3.3 version of qt3 and the current svn 
version 3.3.8 [svn 2145].  I am using mingw "current" version 5.1.3 
from sourceforge.  An earlier version of mingw won't compile qt3.

I previously had printer control working with my XP [32 bit] 'visual 
basic' widget, but that widget doesn't allow me to set the printer 
address to 33792, which is what is needed with XP64.  I know that 
inpout32 will allow me to set it, as that is how linrad is controlling 
the printer.  But for some reason my combination of qt3 and mingw32 is 
not compiling the code necessary to run the dll.  I DO have all of this 
working under Linux, so comments to the effect that I should use Linux 
are not helpful.  I want to understand what is going on and to get this 
working with Windows XP64.

I put my code at http://www.nitehawk.com/w3sz/form1.ui.h and
http://www.nitehawk.com/w3sz/main.cpp

, but what I think are the only 2 relevant lines of code are above near 
the top of this email.

The LARGE error file I generate when I run make [actually, 
make-mingw32] [810 KB] is at http://nitehawk.com/w3sz/err.log

My Environment settings are at:
http://nitehawk.com/w3sz/set.log

Does anyone have any suggestions as to what might be going on here?

A trial of compiling with Microsoft Visual C++ 2005 Express is on hold 
due to multiple 'path' errors when that route is tried.

I apologize for the bandwidth but I have come to a dead end here. I 
would have thought that a bit of Googling would give me the answer, but 
I've been at it all day with no solution yet.

Thanks in advance, and

73,
