I'm trying to batch print PDF files, something that this code will do if compiled but I'm failing to understand how it works..
It looks like it opens Acrobat Reader and uses a print "verb". I thought that was just something you could do to print text file on the command line (issue "print myfile.txt" - but if I do that on the command line here it printes the contents of the PDF, not the rendered PDF file. This code does seem to work, so if anyone can give me a hand porting it to PB and understanding how that ShellExecute is working I'd really really appreciate it!!!
Code: Select all
#include <stdio.h>
#include <windows.h>
#include <winspool.h>

char szAdobe[MAX_PATH];
// Callback for isAdobeRunning
BOOL CALLBACK EnumCallBack(HWND hwnd, LPARAM lParam)
{
char s[MAX_PATH];
// If window title contains match string
GetWindowText (hwnd, s, MAX_PATH);
if (strstr(s, (char *)lParam)) {
// Set the hWnd
hWndAdobe=hwnd;
// Set our flag
isRunning = TRUE;
return FALSE;
}
else
{
isRunning = FALSE;
return TRUE;
}
}
// Determine if Acrobat or Reader is running
BOOL isAdobeRunning()

EnumWindows (EnumCallBack, (LPARAM)szAdobe);
