Manually changing it to set the property (Text [Set]) works just fine, but doing that for every date field in our app is not happening, obviously. What, exactly, does SetText do under the hood? Can I perhaps hook into WndProc?TestComplete and Windows Forms MaskedTextBox- Create Windows Forms project, add a MaskedTextBox to the form, give it a date mask e.g. "09/09/0000". - Add a button, add this to the Click event handler MsgBox(MaskedTextBox1.Text) - Run, enter a date, click the button. You'll get a dialog showing the value. Now do the same in a recorded TestComplete project. The value is set on-screen, but the value in the dialog is blank! I'm evaluating TestComplete, and this sinks us pretty hard. My guess is that this is a bug in the MaskedTextBox, not necessarily TestComplete, but not working is not working... Any ideas?
