Flood counting pixels (Counting pixels instead of filling with a color) Member 441789219-Dec-09 8:17 Member 4417892 19-Dec-09 8:17  Hello. Does someone have a simple sample for flood filling for a picture, or even better a sample of how to count the pixels instead. What I want is to count the pixels with the same color that touch eachother. I saw some flood filling you could rewrite, but those are very complicated so a simple sample for that would also be great. Hope you can help.

(I even tried modifying CreateParams to use the parameters the window does- no luck) How can I implement this kind of Window? Re: Glass bordered Nonresizable window without title bar?

Even the borders Edit: Aero Glass Borders on popup Windows[^] modified on Saturday, December 19, 2009 4:23 PM Progress bar implementation tasumisra19-Dec-09 7:03 tasumisra 19-Dec-09 7:03  Hey Guys, I am performing restore and backup of databases in my application .Can anyone help me to implement a progress bar for this whole process ? Thanks, Vikas vikas da Re: Progress bar implementation Luc Pattyn19-Dec-09 7:52 Luc Pattyn 19-Dec-09 7:52  Hi, CodeProject hosts a lot of articles on progress bars, some or good, some not. Progress can only be reported to the user if the operation consists of multiple steps and you know (or can somehow estimate) the relative duration of each step. If OTOH your backup basically consists of a single SQL (or other) statement, then it is impossible to report progress as there are only two states: nothing done (before the statement) and all done (after the statement).

Re: GDI Get Painted Points Luc Pattyn19-Dec-09 5:51 Luc Pattyn 19-Dec-09 5:51  hi, that is bad code for several reasons: - when no longer needing objects that you created and have a Dispose() method should be disposed, especially the expensive ones such as a Graphics; - Pens.Red is for free; - within a Paint handler, the Graphics is for free, see PaintEventArgs. - you should not use CreateGraphics except as a last resort. I suggest you read this[^]. BTW: the pixels modified by a DrawLine are on or near the line you paint, which exactly depends on some parameters, such as SmoothingMode I guess.

What do you mean? you want to get coordinates of already pained point? (All points on screen are painted) Or are you refering to? pPoint.X pPoint.Y also Graph.TranslateTransform can affect your coordinate system Re: GDI Get Painted Points dataminers19-Dec-09 7:38 dataminers 19-Dec-09 7:38  For example I write following code; Point p1 = new Point(0, 0); Point p2 = new Point(3, 0); DrawLine(p1, p2); I want to get painted Point; "0,0", "0,1", "0,2", "0,3", Re: GDI Get Painted Points Dave Kreskowiak19-Dec-09 8:18 Dave Kreskowiak 19-Dec-09 8:18  You'll need to implement you're own line drawing algorithm to return those points. There is nothing in the .NET Framework that will do it for you.

Datetimepicker PIEBALDconsult19-Dec-09 4:17 PIEBALDconsult 19-Dec-09 4:17  No such thing. Plus you should always use an ISO 8601 format, e.g. yyyy-MM-dd. Re: Help me! Datetimepicker Saksida Bojan19-Dec-09 6:50 Saksida Bojan 19-Dec-09 6:50  I Think that is connected to OS language. Since I am using XP with Slovenian language. And I useded DateTimePicker, I got in Slovenian names. You must be missing something. (XP have 3 difrent location settings in Regional settings) gonna tried at home, where I have Win7 english Re: Help me! Datetimepicker Saksida Bojan19-Dec-09 8:40 Saksida Bojan 19-Dec-09 8:40  Now i am home and i know what affects it. Under Region And Language (Where you see date and time formats), you need to change Format to specific country Re: Help me!
