MFX Draw: 16-Bit Device Drivers Incompatible with Windows NT (102710)
The information in this article applies to:
- Microsoft Windows NT Server 3.1
- Microsoft Windows NT Workstation 3.1
- Microsoft Windows NT Advanced Server 3.1
This article was previously published under Q102710 SYMPTOMS
You may get unexpected results when you copy items from Micrografx
Draw to the Clipboard and then paste them into another application.
You may lose Draw data on the Clipboard when you exit Draw.
Import and export functions may fail.
CAUSE
These problems are caused by Draw's use of 16-bit graphics drivers,
which Windows NT does not support.
When you copy something to the Clipboard, Draw tries to use its own
16-bit driver to render the image in a private picture format. Draw
calls the CreateDC API for this purpose:
CreateDC(lpDriverName, lpDeviceName, lpOutput,lpInitData)
where the parameter "lpDriverName" is a long pointer to a null
terminated string specifying the MS-DOS filename, without extension,
of the driver ("MGXWMF.DRV", "MGXPCX.DRV", and so on). Under NT, this
call fails because NT does not support 16-bit drivers.
The 16-bit driver also causes loss of data from Clipboard when you
exit Draw and failure of import and export functions, which rely on
the 16-bit driver.
WORKAROUND
To avoid losing Clipboard data, make sure you use it before you exit
Draw.
STATUS
No workarounds are available to avoid unexpected results and
import/export failures.
NOTE: Images from other programs exported in Windows to .DRW format
can be edited in Draw when running in Windows NT. However, the central
problem will remain until there is a 32-bit version of Micrografx Draw
or a 32-bit device driver it can use with Windows NT.
