there are only two colors involved. Build a GraphicsPath and use Graphics.FillPath; I am not sure how it fills when edges intersect, you'll have to test it.

I may be making a mistake here but doesn't GraphicsPath has a method to do exactly this?
bool GraphicsPath.IsVisible(Point)
[Indicates whether the specified point is contained within this GraphicsPath.]

Nice, I keep forgetting that method exists. It means we don't need a bitmap after all, which makes overall sizes and integral values irrelevant. Construct the path and interrogate it!
FWIW: when lots of points have to be checked, a bitmapped approach may still be the faster solution.

I want to deploy my application which requires .Net framework, SQL Express as prerequisites. So i created a setup project in VS2008 and selected .Net framework and SQL Server 2005 Express.
Now while installing my application at client's site, it first installs .Net framework followed by SQL Express 2005. But while installing SQL Express it does not prompt for the user to set the password for 'sa' user. There is no dialog displayed for user selection. It installs windows authentication mode. Is there a way to set the SQL Server autentication mode. Please note that i dont want to install SQL Server Management studio.
Your help is appreciated
Thanks

I have an managed C++ dll lib. It has claas info like below
namespace tests
{
public enum class clours
{
Start = 0;
Red = 1;
Green = 2;
Blue = 3;
End = 4;
}
}
I have written a client application in C# and load the dll dynamically(I am using reflection). I want to access the enum members and values between 'Start' and 'End' from the client application.

|
|
|
|
var fields = (from field in type.GetFields()
where (field.Attributes & System.Reflection.FieldAttributes.Literal) != 0
select field).ToArray();
Don't forget that without enum class or enum struct this code won't work.
The criteria in the where clause assumes that for a CLR enum, no fields other than the enum's constants marked as literal. I'm not completely sure if there are no special cases but you should research that a little bit before trusting that criteria.

Is there a way to display digital waveform in c# and also change its values?
|
|
|
|

You could always use this[^] to display the graph. If you want to change values, you want to manipulate the underlying data rather than the graph itself, and let the graph reflect those changes.

Load of ways:

|
|
picturebox1.ImagLocation="....";
|
|
|
|
|
I wanna to use the image in solution but not in debug folder (I mean that after i build the project i dont want to show the image to user client!)
in user computer they wont have the folder that i used in my solution!
|
|
|
|
|
as i know when you build the program you cannot add components to it (as i know)
instead you can make the folder that you will get the photos hide(it an idea!!!!)
|
|
|
|
|
I wont add components .as i said before i wanna to add photo to picturebox that get the photo from the folder in solution and the folder wont be seen after building the project( like folder :Bussinesslayer/DAL/BLL)
|
|
|
|
|
first you should import the photos from picturebox.image properties then you will find them in SolutionName.properties.Resources.PhotoName:
picturebox.image=SolutionName.properties.Resources.PhotoName;

Dear All,
I created a Windows Service and a installer project for it. The problem is that ofter unistalling the service through the setup file or through 'Add/Remove Progrmes' in Win XP, the service is still present in the 'Services' list in the system.' I have to use the command prompt of Visual Studio to remove the service from the list.
How can i fix this problem?
Thanks in advance.
