Hi David,
Thank you for posting in the community!
Based on my understanding, you use PrintDialog class to display a print
dialog. If the user have selected some text for print, you want the print
dialog to select the "selection" option.
===========================================
Actually, .Net PrintDialog class does not expose the way to select this
option button.
I think the workaround is in the initialize period P/invoke FindWindow
win32 API function to get the window handle of "selection" option button.
Then send a BM_SETCHECK message to this option button to set it checked.
Because PrintDialog is a sealed class, to hook into the initialize period
of PrintDialog, you should inherit from CommonDialog, do like follow steps:
1. Create a new class inheriting from CommonDialog
http://www.dotnet247.com/247reference/System/Windows/Forms/CommonDialog.aspx
2. Override the RunDialog method and call the standard windows API
functions to bring up a common dialog
3. Handle the WM_INITDIALOG messages in the HookProc the adding the
functionality to the common dialog
So the entire process is too complex and cost too much for you. I think it
is a good idea to leave away from this complex, leave this selection to the
user.
==========================================
Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be
of assistance.
Have a nice day!!
