Determine when dragging a form has stopped.How can I programmatically determine when a MDI child form has been dragged
from one location to another within its MDI parent form? Ideally I'd like to trap some event that occurs when the dragging has stopped. Thanks. Id say the dragging stops when the user lets go of the mouse button...
As for stopped moving I guess you could make ur own event.... Im a noob tho so im not sure...

If you are not sure, or don't even have the foggiest idea of how to be helpful here, then please feel free to NOT respond. The problem with responding with useless information - as you did here - is that it creates the perception that the question has in fact been answered. The problem here is that others who might know the answer or could be actually helpful might not bother to read the original question. BTW: How in the world would you- in your best of intentions - think that your answers could be in any way helpful? Am I supposed to read what you wrote and think - "yes - that's it!". Sheesh. "user let's go of the mouse button. Okay - great - how do we trap for that? "make ur own event" - what? "ur" --- you are apparently so lazy that you can't even write out "your". And even if I can get past that (which I can), then, okay I'll write my own event... followup question for you then - when do I fire my own event? - let me gusss - when the user "lets go" of the mouse button. Okay great - how do we determine that? Oh, let me guess - I'll write my own event.

The more newsgroups you include, the more likely it is you'll attract answers from someone who isn't going to provide the answer you want or think is useful. Also, I don't really see the point in berating the answer you got. Maybe it wasn't really helpful, but I didn't see any sign that the guy was yanking your chain. Assuming he was really trying to help, criticizing him isn't a great way to encourage other people that also might really try to help. Pete <snip>
RE: >>I don't really see the point in berating the answer you got. The point is to discourage such useless posts... my little part to help with the signal-to-noise ratio. And yes, I know, explaining that, in itself, hurts the signal-to-noise ratio... RE: >> broad, inappropriate cross-posting. Gotcha - maybe just the winforms group would have been best. I did think about it before doing it, though... seems like nobody knew the answer to my earlier/similar question from yesterday - so figured I'd widen the scope a bit and refocus the question. I didn't know that 3 groups would be considered as "broad"... I'll take that into account in the future. Back to the OP: After all this there is apparently there is no way to determine when a user has stopped moving/dragging a mdi child form. Do you have any ideas on that? Sorry,
Perhaps it wasnt helpful...but sometimes when no one else can answer little things can trigger to help you think of other things...just offering what little I know is all... I guess what I was trying to get at, was that do you mean drag and drop as you want to track when the mouse button is let go, or do you mean move as in when the drag moves over a pixel...I realise i didnt state that very well and that wasnt very helpful. How could you have an event that determines when it stops moving? that would require a timer and as far as I know there is no property that stores one. So I'd guess youd have to make your own...

It won't work in this case because mouse events are only raised in the client region, but his suggestion is used commonly in many other situations so you really owe him an apology. On topic, See if you can figure out what to do with the following: private const int WM_NCMOUSEMOVE = 0xa0; private const int WM_NCLBUTTONDOWN = 0xa1; private const int WM_NCLBUTTONUP = 0xa2; private const int HTCAPTION = 2; private const int SC_MOVE = 0xF010; private const int WM_SYSCOMMAND = 0x0112; protected override void WndProc(ref System.Windows.Forms.Message pMessage) { switch (pMessage.Msg) { case WM_NCMOUSEMOVE: Console.WriteLine("WM_NCMOUSEMOVE"); break; case WM_NCLBUTTONDOWN: Console.WriteLine("WM_NCLBUTTONDOWN"); break; case WM_NCLBUTTONUP: Console.WriteLine("WM_NCLBUTTONUP"); break; case HTCAPTION: Console.WriteLine("HTCAPTION"); break; case SC_MOVE: Console.WriteLine("SC_MOVE"); break; case WM_SYSCOMMAND: Console.WriteLine("WM_SYSCOMMAND"); break; } base.WndProc(ref pMessage); } Show quote

RE: the other guy - the self-poclaimed "noob" (whatever that is), here is some excellent reading: http://www.catb.org/~esr/faqs/smart-questions.html While that article is about posting questions, many of the points and certainly the spirit of the document can easily be generalized to responding to questions. The document is a bit lengthy, so I'll point out that one important point the document states is that it's totally unhelpful - even irrellevant to anything - to point out oneself as a "newbie" (or "noob" for the lazy). Why the self-effacing blather? It's unprofessional, unhelpful, and irrellevant. And we're not "texting" each other here. So no need to go with all the contractions... r u ok wit dat? ROTFLMAO! How are we supposed to take you seriously when you come to this group with that (rhetorical question). -Bob if its a decent document, and I don't know cause I'm not going to read

> it....Id say it says stuff about pejoratives and narcissism... Speaking of pejoratives - referring to onesself as a "noob" is quite the pejorative. And I agree with you 100% if you are implying that such pejoratives should be avoided. -Bob  |
