This is the MSDN page[^] for the Polygon function in gdi32. You need to set the brush and fill mode first and it will draw it filled for you.
[Added]This page[^] gives you the gdi+ function signatures[/Added]

Thanks, but how do I apply this using C# code? Oh, and what you showed me is normal GDI. System.Graphics uses GDI+. Is this any problem? (I have heard normal GDI is faster, though; is this true?). Here is a slightly modified version of the context within which the code is used:
if (!isPerformanceTest)
{
Renderer.Render(newDrawing , g));
}
bitmapData = bitmap.LockBits(
new Rectangle(0, 0, (int)(Tools.MaxWidth / reduction), (int)(Tools.MaxHeight / reduction)),
ImageLockMode.ReadOnly,
PixelFormat.Format32bppArgb);
I would like some code if at all possible.

I'd have to work at and test a C# PInvoke method. I have edited the original post with a link to the MSDN GDI+ page[^] with the GdipFillPolygon function signature (gdipluss.dll).

Here is the complete source code of the program. It may only be used under the provisions of the GPL. This is not Roger Alsing's original work; it has been very highly optimized. Further optimization of other sections is almost useless without optimization of the renderer. I tried Direct3D, which was very good, but it had WAY too many bugs to even attempt to continue on. The Render method is in the Renderer.cs file and is called by FitnessCalculator.cs, which is in turn called by MainForm.cs. The DnaPolygon.cs and DnaDrawing.cs files are used extensively.
Download Source Code
The two lines of the Render method that I mentioned in the original post together take more than 70% of the CPU time of the program.

Hi,
I am trying to create a web software that will get a URL where is has a long list of links (each link lead to a pge where i want to check a certain filed and get its data), and from that moment on will run alone, using the 'back' option to get back to the previous page where it has the list, then entering the next link and so on.
How can I do that? I know I can cntrol IE but I am not sure if it will be enough...
Thanks for any help ninjas

You don't need a browser for that, it is much easier using just (Http)WebRequest and (Http)WebResponse, then somewhat parse the HTML page you get.
BTW: Make sure to keep a list of URLs already visited, to prevent running in circles.
|
|
|
|
|
Hi Luc thank you very much for your help!
Will i be able to navigate from that page? As if clicked the 'back' button?
and thanks for the tip with list it will definitely help me saving some time
|
|

There is no need for going back; this is how I make a sniffer:
1. create a list of pages already seen; it starts out empty;
2. create a list of pages to visit; it starts out with a single URL;
3. fetch the first page in ToVisit; remove it from ToVisit and add it to AlreadySeen;
4. parse the page and add all URLs of interest to ToVisit, unless they are already in AlreadySeen;
5. if (ToVisit not empty) goto 3
remarks:
1. one advantage of this approach is it performs a breadth-first traversal, so it is not wandering off right away.
2. of course you must be careful to limit the reach of the sniffer; maybe you don't want to parse pages whose URL don't start with the URL of the very first page (so www.XXX.com will visit and scan www.XXX.com/more but will not dive into www.microsoft.com)
|

|

Thats a great way and I would definitely use it.
What happens when you dont have a list in advance, and you want keep flowing on the list? it is a large list on that page and getting all its url's will be force me to actually get there...

Sorry, I didn't understand that.

Hello
My apologies to jump into this thread but I have a very similar question
My goal is more to emulate command on a web page than simply browse the different link from pages to pages
The problem is How to identify command syntax ?
In some case I can use Firebug to see what command is sended and then reuse the command with specific parameters using Csharp and an HttpWebRequest
But Firebug do not always shows the command
Is there any way to "sniff" commands and see exactly what is sended ?

There is no general solution AFAIK. The page could be full of JavaScript, it could calculate whatever it chooses, and then fetch another page from there.

Thank you Luc
In my case it should not be too complicate I hope
The control is a dropdown list and I can already get the elements of the drop down in the Html content
The problem is that I can't see what command is sended when the dropdown value changes
What would be a good approach to get it ?
N.B : I do not understand why is some case such commands are shown into firebug and in other case not ?
What can be the difference ?
|
|
|
|

it could be as simple as an HTML form with a "dropdown"; the form's action could be a GET (=regular URL will be used) or a POST; the inputs of the form then get appended to the URL. That would really only fetch a new page upon pressing a button.
and it could be almost anything when JavaScript is used, as with an OnClick method, and maybe an OnSelectionChanged method or something similar. I can't tell you more.,

Thank for your help Luc
I will continue to investigate.
I'm certainly not the first to try to automate a web page and it must be a way anyway to check what the page is sending to get an answer
I can understand that with a WinForm application it is not so easy to trace the event and methods. Anyway a good debugger can do it
I can't believe that it will be more complicate to get the outgoing flow from a web page ?
I will continue to learn about this interesting topic

| Hi. Is it possible to have a MAC OS look in your WinForm controls? Wamuti: Any man can be an island, but islands to need water around them!

Why on earth would you want to do that?
If your app is the only mac-a-like on a windows system, it is going to look pretty silly.
You can do it, if you must, but I think you will have to draw all the controls yourself. And the menus. And the Form borders. And the scroll bars. And the system buttons. And the cursors. And the Message boxes. And the standard dialogs.
It would be a lot quicker, and cheaper, to buy a mac instead.You should never use standby on an elephant. It always crashes when you lift the ears. - Mark Wallace

You'll probably get a much better response from telerik..45 ACP - because shooting twice is just silly

I have created a check that if path exsist by creating and removing temporary folder. Is there any better check to check if a path inside string is valid?
Edit: Rephased
Edit 2: More Info
I used like This: (From Memory)
String path = "c:\TempCacheFolder";
Directory.CreateDirectory(path);
Directory.RemoveDirectory(path);
I needed to know if imputed string is valid before creating. I am currently designing Cache Engine for my custom control. The property CacheFilePath has get and set property. When someone programaticly enter an invalid area where it can't be written, without actually creating it before it is needed. And there is error within my approach. If I create directory with a path that have more subfolder that doesn't exsist:
Example:
Faze1. Test Create a folder.
C:\MyApp\UnkownFolder\Unkownfolder2\TempImageCache.
Faze2. Remove Folder. (Will remove only TempImageCache)
I wan't to avoid this needless step. I only wan't to validate, that the unknown directory can be created without actually creating before needing.
I am sorry if I was too cryptic about my previous postsmodified on Saturday, March 6, 2010 9:32 AM
