Hello Vee world !

I'm trying to develop a driver for the brand new HP M Module (HP E2259A)
but I have problem to compile it.
It's not HP Vee stuff, but maybe one of you has already a driver or any
advice to give ... (see below for more details)

[2] HP 2251A User's Manual

PROBLEM :
I'm trying to reuse the program examples given in the doc. in reference
but I get a link error when compiling.
I use :
MS Visual C++ 5.0
Windows NT 4.0 SP3
HP I/O Libraries for Windows 95 and Windows NT Release D.02.00
VISA Library version 1.0.

* MS Visual C++ settings :
The source is the one given pages 34 and 35 of doc. [1], with
corrections of bugs (missing ';'; typing errors 'err_status' instead of
'errStatus' ....)

The compiler target is a win32 console application, not using MFC. The
projext options are :
/nologo /MLd /W3 /Gm /GX /Zi /Od /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D
"_MBCS" /Fp"Debug/M_Module.pch" /YX /Fo"Debug/" /Fd"Debug/" /FD /c

The Tools/Options/Directories added are the pathes to
vxipnpwinntlibmsc, vxipnpwinntinclude, siclc

* Error message :
Deleting intermediate files and output files for project 'M_Module -
Win32 Debug'.

Hi Mike,

It sounds me like you are reading the message with a bad format. I suggest
you, for testing pourposes only, to include the read part of the sockect
into a loop that read one byte (in bynary format) until the end of the
message. Once you are able to know which is thespecific message and its
format you could design a better sokect structure. Maybe your problem is a
format problem!

Hope this help,

Sure. The image file is just a bunch of (generally) binary data. Once
you know the format it is simple for VEE to read it in.

A while back I had some broken quicktime files (wouldn't play) so
figured I would see what VEE could do for me. Ended up reading
the data into a byte (8 bit integer) array and displaying it
on a XY plot. Very interesting- could visually see the headers and
whatnot.

By comparing a working file with a non working one I was able to figure
out what was busted in the header and then repaired it in VEE and wrote
out the result. Ended up with a program that could read in the busted files,
repair them, and write out correctly.

If you know the format (I didn't) it would of course be much easier.

Hi All,

Is there a function in Vee to get the current resolution details of the PC ?
I'm running Windows 95.
If not contained in Vee, are there DLL's supplied with Windows that generate this information.

Thanks for any help on this,

James
