1- What is the easiest way to display HTML document in a Windows Form

Best way to display HTML in Windows Forms is to use Internet Explorer control. This control will be available in C# 2005 (like typical .Net control), but it is possible to use it in current version also (In Toolbox click on "Add/Rmove Items" and select "Microsoft Web Browser" on Com Components page).

You can navigate browser control to html page from html file, from url and also to resource of win32 dll file (something like res://C:\WINDOWS\system32\shdoclc.dll/navcancl.htm).

There's going to be a .Net control for the IE window in C# 2005? That's sweet. Using the Microsoft Web Browser is great and all, but sometimes it's a pain. I hope that the .Net control will be a little easier to work with. Is there anywhere where I can go to read up on it?

It is wrapper of IE object, but it should be easier to use it from managed code. I don't have any experiences with it, so i can't tell if it is really easier, but i hope so... Smile | :)

You need to visit the Crystal Reports website and register the version that came with your VS 2003. Then you need to read their install/use PDF. It tells you which files you need to include in your project and how to register the license to that project.

Someone wrote an article earlier this week on using PInvoke to execute x86 Op Codes from within a C# application.

For the life of me, I cannot find it. Can anyone point me in the direction to that article?

Can anyone help me to know how can I debug C# scripts? e.g. for VB/JAVA scripts we use 'Stop/debugger'(respectively) keyword & it starts debugger. Likewaise how can I start debugger from C# scripts?

Thanks from me.

This code should launch and attach a debugger:

System.Diagnostics.Debugger.Launch();

And then this code should signal a breakpoint to it:

System.Diagnostics.Debugger.Break();

Thanks for reply. this works but unfortunately does not solve my problem. When I select debugger for debugging, it launches my main program in debugger instead of script. I look fofrward to debug only script.

I don't really understand what you mean by script... runtime generated code? But anyways, if it's not part of the main application, I don't know of a way to debug it.

Searching for Carriage Return in string?

What might be the best way to check a string for an instance of a carriage return?

Would something like this work?

if ( s.IndexOf(Convert.ToChar(13)) > 0 )
{
//CR Found
}

Is there a better way?

Re: Searching for Carriage Return in string?

Marginally faster (without Convert) and correct (will also find CR at the beginning of the string):

if (s.IndexOf('\r') >= 0)
{
}

But it depends if the string was created on windows, unix or mac.
On windows you'll have \r\n
On unix, just \n
and mac just \r
so if you have unix string and search for \r you won't find new lines.
You can use Environment.NewLine to get the version of new line that your program is running on.

He was asking for Carriage Return, not newline character(s).
But otherwise, you're correct Poke tongue | ;-P

Quite easy. There's a class in the framework for this: System.Web.Mail.MailMessage.
You might want to look it up in the framework documentation.

I found a way to move the mouse:

const int MOUSEEVENTF_LEFTDOWN = 0x02;
const int MOUSEEVENTF_LEFTUP = 0x04;
[DllImport("user32")] public static extern int SetCursorPos(int x, int y) ;
[DllImport("user32")] public static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);
private void button1_Click(object sender, System.EventArgs e)	{
	SetCursorPos(200,200);
	mouse_event(MOUSEEVENTF_LEFTDOWN,0, 0, 0, 0);
	mouse_event(MOUSEEVENTF_LEFTUP,0, 0, 0, 0);
}

can this be modified to broadcast keys?

There is a much easier way to move the mouse pointer:
Just set the System.Windows.Forms.Cursor.Position property.

To broadcast keystrokes, you could use the System.Windows.Forms.Sendkeys.Send method.

I also found this webpage describing how to send keyboard events:
http://www.mkssoftware.com/docs/man1/sendevent.1.asp[^]

However, i have no idea what it means, could someone explain it to me?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
