I'm using webbrowser control with drawtobitmap method to get the image of the html page.
When I call MakeTransparent(backcolor) i get text with artifacts(The halo effect).
How do i get rid of these artifacts?

Err... okay then.
The way i see it is then, the only colour you KNOW is the original colour of the text, so if the text was white, somehow make every colour that ISN'T white transparent. How you'd go about making every coour in the image transparent except white? You can figure that out.
Or perhaps you could make the text transparent, and do something with that... does GDI+ have masks or anything? I don't know.

Course Instructor’s View:
Course Instructor should be able to Add/Edit/Delete the Content. i.e.
Add/Remove Course outline document.
View All /Add/Edit/Delete Assignments
View All /Add/Edit/Delete Quizes.
View All /Add/Edit/Delete Lecture Slides.
View All /Add/Edit/Delete Handouts.
View All/Add/Edit/Delete Announcement.
1. You have to save the information related to these documents in the SQL Server Database.
Course Outline: Date Given, DateUploaded.
Assignment : Title, Description, DateGiven, DueDate, UploadedDate, FileLocation.
Quiz : Title, Description, DateGiven, UploadedDate, FileLocation
LectureSlides : Topic, Description, DateDelivered, DateUploaded, FileLocation.
Handouts: Topic, Description, Date Given, DateUploaded, FileLocation.
Announcement: Text, AnnouncedDate, Priority(Low/Medium/High)
{“DateUploaded” should be inserted by the program itself, using DateTime.now property.}
{“FileLocation” is the full path of the uploaded file.}
2. In the datagridview, if the user clicks a row, another screen should be opened for a detailed view of that particular Quiz/assignment/test, where he/she would be able to edit the information. He also can Upload a file here.
3. All these content files can be of .doc/.pdf/.html/.ppt/… format. Teacher should be able to browse the file using “fileOpenDialog”. The selected file should then be uploaded/saved to the respective location.
{Hint: see “fileopendialog” and “System.IO.File” or “filestream” class methods, for saving these files}
4. Output Path(where all the course files are to be saved) is not to be hardcoded, rather it should be read from “app.config” file. See this link for help.
http://www.codeproject.com/csharp/SystemConfiguration.asp
5. Course Information has to be maintained in proper folder hierarchy. E.g. the hierarchy of Visual Programming course folders should be like this.
? Visual Programming
? Assignments
? Quizes
? Handouts
? Tests
e.g When the first Quiz is to be added, your program should create a folder named “Quizes” and add the quiz file at this location.. OutputPath\CourseName\Quizes\QuizFileName.doc , You have to do the same for Assignments, Handouts and Tests.
6. Create a table having CourseInfo, where each row corresponds to a course. This table should have CourseCode, Title, Instructor, CourseProfilePath.
can anybody help me in this problemm..........

Wow, I don't know what makes you so dumb but it really works. We don't do homework for you.

Simple. Go do your own homework. Ask people for help when you have a specific problem.

Hi all
have a good day
how I can write a good code for my apps
I mean , I know a lot of stuff ( API , WMI , Database , Drawing , Encryption , Sockets .... )
and every time I write a program it's work very fine ,
but I didn't like the code that I write 
(I need my code to be like professionals code)
for example .... I used this in one of my apps
[code]
lbl1.Text = Environment.GetFolderPath(Evironment.SpecialFolder.Personal);
lbl2.Text = Environment.GetFolderPath(Evironment.SpecialFolder.Desktop);
.
.
.
.
all the special folders
[/code]
but someone professional wrote it this way :
He created a new class file ( Folders.cs ) and add it to project
[code]
public class SpecialFolder
{
private static string [] SpecialFolders = null;
static SpecialFolder()
{
SpecialFolders[0] = Environment.GetFolderPath( Environment.SpecialFolder.Personal);
SpecialFolders[1] = Environment.GetFolderPath( Environment.SpecialFolder.Desktop);
.
.
.
.
}
public static string Documents { get { return SpecialFolders[0]; } }
public static string Desktop { get { return SpecialFolders[1]; } }
}
[/code]
------ and he used it like
[code]
lbl1.Text = SpecialFolder.Desktop;
lbl2.Text = SpecialFolder.Documents ;
.
.
.
.
[/code]
would be please advice me what should I read , or what should I learn ..
Kind regards ...

Read articles on this site. Look for articles that get higher ratings and have a read through the code. BTW - the code that you quoted as being written by a professional developer isn't very good. This should have been done in a much more robust fashion, e.g.
public enum SpecialFolderType
{
Desktop,
Personal
}Then further on...
private Dictionary<SpecialFolderType, string> _folders = new Dictionary<SpecialFolderType, string>();
...
_folders.Add(SpecialFolderType.Desktop, Environment.SpecialFolder.Personal); .. and so on.
Then you would retrieve it with
public string Desktop { return _folders[SpecialFolderType.Desktop].Value; }Obviously there are more things that could be done to beef this up even further, such as checking values and so on, but you get the idea.

Thank you so much , for your fast , useful replay
- you said : (BTW - the code that you quoted as being written by a professional developer isn't very good.)
Mr.Pete After I saw your code , I believe that you are right .
His code is not very good , but he is better than me , and you are better than two of us ....
thank you ...
Kind regards ...

Code Complete is a very good book for general style issues.
<blockquote class="FQ"><div class="FQA">Stark DaFixzer wrote:</div>lbl1.Text = Environment.GetFolderPath(Evironment.SpecialFolder.Personal);
lbl2.Text = Environment.GetFolderPath(Evironment.SpecialFolder.Desktop);</blockquote>
All that sucks about this is the variable names.
Stark DaFixzer wrote: public class SpecialFolder
{
private static string [] SpecialFolders = null;
static SpecialFolder()
{
SpecialFolders[0] = Environment.GetFolderPath( Environment.SpecialFolder.Personal);
SpecialFolders[1] = Environment.GetFolderPath( Environment.SpecialFolder.Desktop);
This is a waste of time in my book. All it does is rewrap something that is already exposed by the framework, and it obsfucates it. Unless there's ever a chance you want to change where SpecialFolder.Desktop points, it's just a waste of time to do this.

Yes, centralizing things so you can change them app wide in one place is a good practice. Good practices adhered to blindly become bad practices.

1. Datagridview has got a property called DefaultCellStyle which is used to control how cells are rendered in that row.
2. Use MultiSelect property of Datagridview class. You can find selected rows by using SelectedRows property. Intuitive, isn't it?

Create a notify icon for your app, then look at the NotifyIcon.BalloonTip method.

The error should be fine to ignore, I get those all the time.
