The CJ TaskDialog is pretty neat, but it was lacking some features that I required (or at least that I thought would be nice to have) for creating a standard progress dialog for my applications. So I got to work and fought with the control a bit and got things working as I needed myself. The biggest problem was that the TaskDialog control doesn't expose and Hwnd property, and I wanted to add features like auto-dismiss after a time period or at 100% progress, the ability to dismiss the dialog at will, the ability to show no buttons, etc...

Here's the complete feature list:

AutoDismissAfterMilliseconds - automatically close a progress dialog box after X milliseconds
AutoDismissAt100Percent - automatically close a progress dialog box when the progress % = 100%.
EnableButtonsAfterMilliseconds - This will ensure that the buttons are disabled until X milliseconds has passed. This helps prevent accidental button clicks when the dialog pops up unexpectedly.
Dismiss - You can call this to dismiss (close) the dialog any time
The control also automatically disables the buttons when it does no have focus. This also helps prevent accidental clicks when you are working on another window and click off that window.
Dismissed Event - You now get a notification when the dialog has been closed.
Timer Event - I added TotalMS (since dialog shown) in addition to the original parameters.
RequestProgressPercent event - This event fires every 200MS or so to request updates to the progress percentage.
BeforeClose event - gives you a chance to cancel the dismissal of the dialog box.
ShowMarquee method - Shows the dialog in Marquee (scrolling) mode
ShowProgress method - Shows the dialog in Progress percentage mode.

Here's the code:

Feel free to use it for any kind of project...no warranty of course. Bug reports and new ideas are welcome.

SOURCE UPDATED IN TOP POST

Fixed a bug that was causing the TotalMS to be miscalculated.

Also, I've added the ability to start the progress bar with an EventCode and then use the EventCode and associated StateCodes in the Timer event to allow for easy state tracking and updating. The sample will demonstrate this clearer than I can explain it, but if you have any questions, please ask here.

Also added the ability to Start/Stop the Marquee (even when in progress mode).
