PrintTextFile hangup

[Reinhard_F_Bentrup]

When I call PrintTextFile LabWindows/CVI hangs up and can only recover by Terminate Application. I'm calling windows PrintDlg subroutine before that but all variables set properly. Any idea?

[RobertoBozzolo]

Does this problem happens only with PrintTextFile or with other printing functions like for example PrintPanel?

I passed a lot of trouble some years ago for a new printer driver not following GDI standards (on wich CVI rely for printing). In my case it was a known problem due the printer driver and moving back to an older one solved my problem until I switched to CVI 6.0.

Have you tried with a different printer?

[Reinhard_F_Bentrup]

The problem is the same with other printer drivers. It's interesting that the PrintTextBuffer works okay if I do NOT call the Windows SDK PrintDlg redirecting printing to my individual printer device settings.

Did CVI 6.0 solve the problem?

Hi,

have you tested the PrintDlgEx(...) function? after Windows 2000 PrintDlg() was replaced with PrintDlgEx(). Since the problem is introduced when you call this function I would focus on this part before playing with the driver.

You can also get the CVI 7.0 evaluation version to test it in a newer version. You can find it at http://www.ni.com/cvi

I hope this helps.
