Topic: Close TaskDialog or Hide Buttons

Subject: Close TaskDialog or Hide Buttons

I'm really desperate for a way to either:

A) Close the TaskDialog menu without clicking a button, or
B) Hide a button on the TaskDialog so I can close it with ClickButton (but the user cannot see it or click it).

The reason for this is that I have a marquee style progress bar moving with a separate thread doing background processing. The user has the option to click the Cancel button, but I would also like the ability to close the TaskDialog in code when the thread is finished processing (without clicking the Cancel button in code).

Any chance at all of either (or both) of these in the next release?

Hi,

Why you can't call

TaskDialog1.ClickButton xtpTaskButtonCancel and set some flag variable that you close it manually? :)

But anyway you are right, we need some Close method.

You're right that I could do it this way (and I may have to for now). I was hoping to avoid this, because I am already tracking a somewhat complex state machine in the TaskDialog timer event, and adding extra variables would just add to the code complication...

Hi Oleg,
Sorry for being a pest, but is there any chance this feature (close TaskDialog) could make it into an early build (or at least the next release)?

Hi Oleg,

I'm back to this one as I've found I need the ability to close the TaskDialog by code without showing a button again. Any chance of this? Or could you expose the Hwnd and maybe SendMessage(WM_CLOSE) or CloseWindow would work?

Thanks.

Ok, I've been able to get the Hwnd of the dialog by calling FindWindow in the Constructed event. Unfortunately, I haven't been able to close it. I've tried:

SendMessage(WM_CLOSE) <this get consumed because I also need AllowCancellation = False
DestroyWindow() <Dialog disappears, but does not release itself so the app gets stuck.

Any ideas what I could call to close the window now that I have the hwnd?

Thanks.

Got it...If I set .AllowCancellation = True immediately before I call SendMessage(WM_CLOSE), then I can close the window.

I think I've solved most of the problems that I was having. If anyone else is interested, then here's some demo code:
