From: David on 28 Apr 2010 15:14 Mr. Johnson: What may make menus different -- now that I think about it -- is that menus are in the non-client area of the form not the client area. Will have to delve further to compare how the client versus non-client is handled.

The problem that you are facing has nothing to do with modal, and everything to do in how Windows captures the mouse when the mouse buttons goes down. This is done to see if the button is released inside or outside the window. If it's released inside the window, a click event is generated. If it's released outside the window, it's ignored. Try clicking any OK button, and before releasing the mouse, move it away from the OK button and you will find that the OS has ignored it. Windows does this by calling SetCapture() when the mouse button is down, and calls ReleaseCapture() when it goes up. One solution, and this may not be ideal, is to call the PictureBox's Paint event in the PictureBox's MouseMove event every now and then when you the left mouse button is down for a while. You can save Timer value in MouseDown in a variable, then check the difference in time in MouseMove event. Again, this may not be the best solution.

For Popup menus, VB(and virtually all languages) uses TrackPopupMenu(Ex), but the issue you have is not related to modal behavior.
From: David on 28 Apr 2010 17:39 Nobody: As always thanks for the input. Regarding your suggestion about calling Paint from Mouse using a Timer variable. Not really sure what you're getting at other than possibly trying to create your own "Refresh" in the mouse Event? If this is the case, my guess is that the mouse might hang more than it does because of the time it takes to process all Paint calls. If I have this wrong could you please elaborate. I've seen other programs (e.g. stock charting applications) where they seem to have solved this issue of real-time along with mouse usage -- but unknown how they did it? I mentioned Appleman previously and his concept of a "State Machine(s)" to resolve this type of issue.. Whether I've implemented his concept as intended is unknown -- did my best.

Just a suggestion... If you're referring to the Dan Appleman associated with Desaware, he's been pretty good about conversing directly with me concerning issues with his products/ideas. I think he'd be just as accommodating to you if you were to contact him yourself to get his opinion about how you've implemented is concept. Kind regards, Garry |
