Capture ESC

[Ian Docksey]

In ShowFrmListProc I can elect to click the button with an ID of %IDC_CREATEMergeDataFILE
ShowWaiting dialog opens with a progress bar
CreateMergeDataFile then runs my routine and updates the progress bar
How can I stop this routine prematurely when pressing the ESC key?
You may have a few suggestions for the MODELESS ShowWating dialog!!
Which is a global long variable to say which database to used.

Thanks
Ian

When you get WM_COMMAND/IDCANCEL, there is no BN_CLICKED notification and CBCTLMSG never equals one.

That is, when you get WM_COMMAND/IDCANCEL, escape was pressed regardless of other conditions.
