Well, I am grateful that you take the time to respond.
Still, I had to laugh.
You suggest to spend 1-2 man-years meaning very roughly 100k$ to switch from WinForms to WPF (medium sized application of maybe 10 man-years), all the while being very slow to ship updates because a lot of resources are bound to the migration, risking to go out of business?
:)
WPF is nice but on the far horizon.
Anywho, I will continue searching with what is available on WinForms, there is a scheduler control too.
Thank you!
