Only strings can be passed, hence an string[] array being passed to your entry point method (typically Main) or Environment.GetCommadLineArgs() returning a string[]. Therefore, you should be looking for a way to convert the string. There are many ways to do this, such as Int32.Parse and Convert.ToInt32(String).

how can i execute a file
e.g. if i have a file c:\text.exe or d:\test.htm
So if i have a textbox and the user enter the filelocation enter a filename.

in VB6 there was an execute API, i thougt Shellexecute
But how can i do this in c#

Check for Process.Start() and ProcessStartInfo classin MSDN.

Thanks
But if the filetype is not registered an error occur.
Can i view the 'Open With...' dialog
|
|

Use ProcessStartInfo and set UseShellExecute and ErrorDialog both to true:
ProcessStartInfo info = new ProcessStartInfo();
info.FileName = myTextBox.Text;
info.UseShellExecute = true;
info.ErrorDialog = true;
Process.Start(info); Be sure to read the class documentation for additional members to see what other features exist.

One way to do this is to use System.Diagnostics.Process...
using System.Diagnostics;
.
.
.
//
// opens an instance of notepad with the file c:\mytest.xsd
//
private void OpenTheFileInNotepad(string fileName)
{
Process.Start("notepad.exe",fileName);
}
see MSDN at:

I have used String array and integer for one console application.
But size of the executable is 16kb. can u help me in this view.

Can you explain more the relation of size of executable file with the use of String Array and integer in your applicattion?

I am using a string array which is having 13 constants and i am comparing with other 13 constants.
When i built that executable file its size is 16kb but i feel 16kb is very costly.
Please explain me

Is it? Then perhaps you should consider using something other than the .NET Framework. I have done some experiments and the smallest application I could build was 16kb.
Also consider that when your application is running it will be loading .NET Framework DLLs. The 16kb size of this executable is a drop in the ocean compared with the size of the Framework.

Yah, they are really small in size. The only time I got smaller than this, somtimes in VC6 which I used some win32 applicationns with some specific compile attribute which lead to very small size like 3 to 5 Kb.

just wondering what methods do i need to override to be able to change bankground color of the status bar? set for exemple a gradient fill backgroung like with iexplorer/explorer.
so far i got just been able to have the devider but no bg 
private void statusbarDrawItem(object sender, System.Windows.Forms.StatusBarDrawItemEventArgs sbdevent) {<br />
StatusBarPanel ssb = sbdevent.Panel;<br />
Rectangle rect = sbdevent.Bounds;<br />
<br />
sbdevent.Graphics.DrawLine(new Pen(Color.White), rect.Right-1,rect.Top,rect.Right-1,rect.Bottom-2);<br />
sbdevent.Graphics.DrawLine(SystemPens.ControlDark, rect.Right-2,rect.Top,rect.Right-2,rect.Bottom-2);}
|

You want to use Graphics.FillRectangle with a LinearGradientBrush:
private void statusBarDrawItem(object sender,
StatusBarDrawItemEventArgs e)
{
LinearGradientBrush gradient = new LinearGradientBrush(
e.Bounds, Color.Blue, e.BackColor, LinearGradientMode.Horizontal);
e.Graphics.FillRectangle(gradient, e.Bounds);
}

You can read and write XML files (of which an XSLT is another XML grammar) using XmlTextReader and XmlTextWriter, but I doubt this is what you're looking for.
If you're looking for graphical XML editors, you need to search CodeProject and the rest of the web. There's plenty of articles, how-tos, and even sample source and libraries out there. You just have to find them.

Sir i try to explain the problem with a little example. I have a xml file an a xsl file, Now i have three fields in xml file let's say Name, Age, Address. Now i displays these fields to user as labels in windows Form. Now when user right click on any label i will display option to him e.g Font, Color different dialog etc. Now when user picks up the color i have to write that color against that field in xsl. will it be possible with XmlTextReader and XmlTextWriter
Thanx in advance

You mean XML, not XSL. XSL is a transform you apply to an XML file that contains data, unless you mean you need to change that transform in order to add a color attributes of sorts; otherwise, forget XSL for the moment.
You'd be better off using an XmlDocument so that you can easily traverse the DOM. See the documentation for the XmlDocument in the .NET Framework SDK for more information. If you keep track of which label belongs to which element or attributes (there are no fields in XML), you can use XPath to select node (via SelectNodes or SelectSingleNode for example) and then append an attributes. You really need to read the documentation for these classes, though, as well as some of the XML topics in the .NET Framework SDK, which you can view from http://msdn.microsoft.com/netframework[^].

Actually i want to change the transform and that is possible only with xsl. I think as u said that xslt is another grammer of xml. My problem will be solved by XmlTextReader and XmlTextWriter. Whats ur opinion

XSL (deprecated) and XSLT are just XML documents implementing a certain schema. What I said before applies but how you do it completely depends on what content the transform produces. If you are transforming to HTML, then you need to either add a style attribute to whatever element will be output with the color: color; value. If you're transforming to something else, you'll need to change the color appropriately.
And no, I don't agree that using an XmlTextWriter is the right way to do, especially when you clearly have no experience using them. Simply load the XSL document into an instance of an XmlDocument and make your changes to the DOM there. You can then save this XML document to a stream, be it a file stream, memory stream, or whatever. Apply this transform then to your XML document using an XslTransform.
Again, be sure to read the relevent sections of the .NET Framework so you understand what you're doing and not just guessing and relying on IntelliSense. See Employing XML in the .NET Framework[^] for a lot of discussion on the topic, as well as examples and links to the class library documentation.

Hi
Can you let me know the exact difference between these two? and wrt performance which is better and why?
It will be great helpful if u tell me when to for Ref types...
