Opening multiple files in same CorelDraw instance

longimanus said:

Some of you might also have encountered the nasty issue of CorelDraw (CorelDrw.exe) to open a new instance of CorelDraw for every CDR file being double-clicked for opening. After twiddling around and searching the web, I finally found out that CorelDraw.exe is case-sensitive for DDE commands. As such, using the DDE argument 'Open("%1")' won't do anything.

The solution for CorelDraw X4 (CorelDrw.exe) is:

Application used:
"C:\Tools\Office\Corel\PROGRAMS\CORELDRW.EXE" -DDE "%1"

DDE Message:
[O("%1")]

Application:
CORELDRW_MOS

DDE Application not Running:
<empty>

Topic:
System

Corresponding registry file:
-----------------------------------------
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\CorelDRAW.Graphic.14\shell\Open]

[HKEY_CLASSES_ROOT\CorelDRAW.Graphic.14\shell\Open\command]
@="\"C:\\Tools\\Office\\Corel\\PROGRAMS\\CORELDRW.EXE\" -DDE \"%1\""

[HKEY_CLASSES_ROOT\CorelDRAW.Graphic.14\shell\Open\ddeexec]
@="[O(\"%1\")]"

[HKEY_CLASSES_ROOT\CorelDRAW.Graphic.14\shell\Open\ddeexec\Application]
@="CORELDRW_MOS"

[HKEY_CLASSES_ROOT\CorelDRAW.Graphic.14\shell\Open\ddeexec\Topic]
@="System"

This would be perfect if it fixes the multiple launches of CorelDraw, but I don't know how to implement what you have above? Could someone explain it to me with steps? I don't know much about working in the Windows OS.

Thanks.
