Hello vrf

>Place the entry on the clipboard and then paste it to the console with

What does the hex values mean, and what is the purpose of the postmessage
call?

i can see that the prototype for postmessage is:

BOOL PostMessage(

    HWND hwnd,     // handle of destination window
    UINT uMsg,     // message to post
    WPARAM wParam,     // first message parameter
    LPARAM lParam      // second message parameter
   );

but how does one get the hex values ?

Regards

Has anyone ever had the change to interface with a DOS command window?

I have a program that requires user inputs, that can not be
handles as parameters. I was wondering if there was a way in
VEE to handle this with out manually entering the data?

Thank you

Hello Amrik,

EasyLabel software does have ActiveX support, which shows up in the VEE
ActiveX controls and automation references, after installing the EasyLabel
software. I just can't get the commands to work, and am fumbling around in
the dark. I thought I might find someone with an example program here.

I have also contacted the "Tharo - EasyLabel" customer support, but haven't
heard back yet.

We have many installations using this software as our standard (in manual
mode), so I am stuck using it too.

Thanks,
Tom Daniels

Hi Daniel

I have used bartender to print labels, and a library of vee activeX
controls
came with it, that is why I chose it.

I am not familiar with easy label, but I would suggest finding out if easy
label is active x compliant, and if so, I would suggest getting in touch
with the creators and asking them for examples.

Should you choose to use bartender I could supply you with a working
example.

Cheers

Amrik

Subject: [vrf] ActiveX EasyLabel Printing

I have little experience with activeX, so am looking for some help. I have
a program that writes data to be printed to a text file. Then I use an
execute program box to open the printing software "EasyLable", which is set
up to automatically open the label format with the data that I need to
print. What I would like to do next is use ActiveX to automatically print
the label. Has anyone used this software, and have a print example?

Substituting symbolic names, the call is actually:

PostMessage(hWnd, WM_SYSCOMMAND, SC_KEYMENU, ' ' /*Space key*/);

The purpose is to simulate pressing Alt+Space to open the system menu of the
console window.

> but how does one get the hex values ?

Most of them are in WinUser.h (in the Windows Platform SDK or your Visual
C++ package). The Platform SDK can be downloaded for free (over a fast
connection - it's really big) from
http://www.microsoft.com/msdownload/platformsdk/sdkupdate.

You have to drop the "Downloads" menu at the top of the page and choose a
download option. You can install the SDK from the web site or download the
full SDK to install locally.

This will give you all the documentation MS publishes on Windows.

Oops! Wrong name. It's WinOldAppHackOMatic. Sorry. Still can't find any
documentation though. Plenty of people know about it, but nobody seems to
know what the parameters are.

Basically it loads & executes a DOS program under Windows. It does this by
creating a Virtual DOS Machine (VDM) & providing DOS services by
virtualizing all the old software interrupts. On fake Windows, most of these
interrupts are thunked to Win32 calls or Int 7F but on real Windows (NT) you
don't get to touch hardware anymore and those interrupts that try to produce
that message about something is trying to do something illegal.

It gets pretty involved sometimes.
