Re: DragDrop rectangle Christian Graus4-Jul-07 5:34 Christian Graus 4-Jul-07 5:34  If you're new to C# in general, you may be biting off more than you can chew. you want to drag and drop a rectangle, the typical way to do this is to handle mouse events to track mouse position and button status, and keep calling Invalidate() in your mouse move after updating the co-ordinates that your OnPaint will use to draw the rectangle. When you finish dragging, you need to store the location, so your onpaint continues to draw it. Did you also expect to 'pick' a rectangle to drag by clicking on it ? To do that, you work out the co-ordinates of your mouse down and iterate through your list of rectangles, to find out which one the mouse is in.

Re: DragDrop rectangle Christian Graus4-Jul-07 6:17 Christian Graus 4-Jul-07 6:17  No, the rectangle is not a control. In WPF, you can. But, if you're drawing a rect yourself, it's not a control, it can't get an event.

It's a fair bit of code, I can't just whip it up for you. The core thing to understand, is to get your rectangles drawing in a paint event, and to have the ability to change the location of one ( or create a new one ), based on mouse events. I'd start with a List<Rectangle> and a Paint event that draws the rectangles. Then I'd write the code to get mouse events, and draw a rect. Then I'd write the bit that finds a rect based on a click, and moves it. Feel free to ask questions any step of the way, but I'm afraid I am unable to jsut write all that for you. If you ask specific questions as you go, I'll be more than happy to help any way I can Christian Graus - Microsoft MVP - C++ "I am working on a project that will convert a FORTRAN code to corresponding C++ code.I am not aware of FORTRAN syntax" ( spotted in the C++/CLI forum ) c# ravilikesaboli4-Jul-07 5:22 ravilikesaboli 4-Jul-07 5:22  my problem is that when i open a site there is CAPTCHA i have 2 retrieve it buut it ha no reference number only reference site and when u enter that reference site and click it always changes . so i want a code that when i send the URL the captcha along with it should also be obtained.iam working in BOT technology Re: c# Christian Graus4-Jul-07 5:29 Christian Graus 4-Jul-07 5:29  Your first problem is that you didn't offer a subject that tells people what you're looking for. ravilikesaboli wrote: iam working in BOT technology What is that ?

See any issue with this? --- How to get answers to your questions[^] Question about Streams RussBus4-Jul-07 5:00 RussBus 4-Jul-07 5:00  I am new to C# and need some help with FileStream and BufferedStream . I am building a XML editor using SharpDevelop, the editor will be used to encrypt and decrypt files (custom zip files which are XML, and pictures). Only one person should have access to these files at a time and we want to make sure that everything is cleaned up after someone opens the file. Right now I am sure a FileStream to do all of this, I decrypt the file to a folder using SharpZipLib the files are then loaded into the XML editor, once the person closes the file it then takes that folder encrypts all the files and delete the temp folder I was using. Would the BufferedStream be better?

New -> new thid.Height -> this.Height this.Location = new Point(0, Screen.PrimaryScreen.Bounds.Height - this.Height); this.Width = Screen.PrimaryScreen.Bounds.Width; All the best, Martin Re: How do i dock a window to the bottom of the screen? jafingi4-Jul-07 5:18 jafingi 4-Jul-07 5:18  Thanks! It is working! BUT! I could't find the window.. Because it was placed behind the process bar (it was only because I got aero, that i could see it). Do you know how to fix that? Re: How do i dock a window to the bottom of the screen? ken.tachyon4-Jul-07 19:25 ken.tachyon 4-Jul-07 19:25  The problem is in the "Y" axis location. Remember Y = "down the screen". this.Location = new Point(0, Screen.PrimaryScreen.Bounds.Height - this.Height); sets a location specified as x,y points. try: this.Location = new Point(0, Screen.PrimaryScreen.Bounds.Height - (this.Height / 2) ); You should see your line in the middle of the screen. Adjust the second parameter to be where you want it. Re: How do i dock a window to the bottom of the screen? jafingi5-Jul-07 0:32 jafingi 5-Jul-07 0:32  It didn't work perfect, but i tried to use: this.Location = new Point(0, Screen.PrimaryScreen.Bounds.Height - (this.Height + 30)); And that works perfect. But! If i make the processbar bigger, it follows, but if i make it smaller, it is the same place as before, do you understand? Re: How do i dock a window to the bottom of the screen? PhilDanger5-Jul-07 5:02 PhilDanger 5-Jul-07 5:02  Try this: this.Location = new Point(0, Screen.PrimaryScreen.WorkingArea.Height - this.Height); Re: How do i dock a window to the bottom of the screen? jafingi6-Jul-07 1:20 jafingi 6-Jul-07 1:20  Doesn't work when i'm doing this: this.Location = new Point(0, Screen.PrimaryScreen.WorkingArea.Height - this.Height); this.Width = Screen.PrimaryScreen.Bounds.Width; this.Height = 22; Have i made a mistake? Re: How do i dock a window to the bottom of the screen? PhilDanger6-Jul-07 4:04 PhilDanger 6-Jul-07 4:04  Since the code I gave you uses the Height of the object, you need to set the height before executing that line. -- this.Height = 22; //this done first this.Width = Screen.PrimaryScreen.Bounds.Width; //moved here to keep height and width in the same code locations this.Location = new Point(0, Screen.PrimaryScreen.WorkingArea.Height - this.Height); Re: How do i dock a window to the bottom of the screen? jafingi6-Jul-07 4:05 jafingi 6-Jul-07 4:05  Works perfect!
