How about you drop the "Local Time" and use DateTime.Parse/ParseExact/TryParse/TryParseExact?

Hi,

not sure what you want.

1.
http://www.google.com/#q=any+text[^]

2.
Google Search has an API

3.
If there's only one editable control on a web page, it is likely to have the focus, so simply send some text (SendKeys) to the app.

Regex Problem,Extracting text from Table

Hello Everyone,

I am trying to extract the contents of the table from a static HTML file.
Program is almost giving the expected output.

Program :-

class Program
	{
		static void Main()
		{
			StreamReader str = new StreamReader("C:\\AllRoles.html");
			string SFile = str.ReadToEnd();
						
		    Regex regex = new Regex(
				@"<tr>(\s* <td[^>]*>  \s* (?<value>[^<]*?) \s* </td> )+ \s*</tr>",
		 		RegexOptions.ExplicitCapture | RegexOptions.IgnoreCase | RegexOptions.IgnorePatternWhitespace);


			 foreach( Match m in regex.Matches( SFile ) )
			 {
				foreach( Capture item in m.Groups["value"].Captures ) {

				Console.WriteLine( item.Value );
			}
			
				Console.WriteLine( );
			}
				Console.ReadLine();
		}
	}

I am facing one problem there is a comment in between the table content

HTML File :-

<table border="0" cellpadding="5" cellspacing="0" width="100%">
            <tbody><tr>
            <td class="columnheading" nowrap="nowrap">Last Name</td>
            <td class="columnheading" nowrap="nowrap">First Name</td>
           <td class="columnheading" nowrap="nowrap">Role</td>
           <td class="columnheading">Term</td>
           <td class="columnheading">Company</td>
           </tr>
           <tr>
           <td valign="top">

           <!-- Logic Here-->


           Gottlieb

           </td>
           <td valign="top">Pradep</td>
           <td valign="top">President

           </td>
           <td valign="top">8/15/2009 - 9/1/2010</td>
           <td valign="top">DSCMIT</td>

           </tr>
           <tr>
           <td valign="top">
           <!-- Logic Here-->


           Rajesh

           </td>
           <td valign="top">H</td>
           <td valign="top"> President

           </td>
           <td valign="top">8/15/2009 - 8/14/2010</td>
           <td valign="top">BHSIT</td>
           </tr>

I am getting the Output as

Last Name
First Name
Role
Term
Company

and it stops at this line 

Can anyone please help me to solve this problem.

Thanking you,
Naveen HS

Function Call Mechanism

Hi all,

I am looking for a library which can perform the following tasks:

- Taks a description of a method call (e.g. Method name, Parameter name and parameter Value)
- Parse the method description
- invoke a method depending on the parsed description.
- encode the result of the method invocation and pass it as text back.

I know that all of this isn't rocket science, the question is: Is there a library that I can use.

best regards

Lars

Reflection. But it will also need a Type to operate on.

I need to call a function written in C# from the unmanaged code.
The code from where I have to call the function is purely written in VC++ and it come in the unmaged part of the solution code.
Most of the solution is written in C# .NET 3.5.
Please help me out.

Thanks In Advance

So you need P/Invoke, make sure any objects (arrays) you pass get properly pinned, and pass a delegate. All you need should be in my article here[^].

To call the method directly, you're realistically limited to using COM. This means you need to expose you .NET object as a COM object and import the type library into your VC++ application.

Looks like your file is not getting downloaded completely.
Post some code here - maybe someone can help you.

The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

My latest tip/trick - Silverlight *.XCP files

if (dt.Rows.Count > 0)
{
result = (byte[])dt.Rows[0].ItemArray[0];
filetype = (String)dt.Rows[0].ItemArray[1];

}
String new_FileName = Path.ChangeExtension(Path.GetTempFileName(),filetype);
File.WriteAllBytes(new_FileName, result);
System.Diagnostics.Process.Start(new_FileName);

THis is my code
i will get bytes in result array and filetype also.SO depending on that I am opening the file to display the data

In my case the same is working properly but I am using dt.rows(0)("FieldName") instead of Itemarray. May be there is problem while saving it into database.

Hi,

Instead of opening the binary data from db in a file is it possible to store this in a file in some locations given by the user.
Like if my binary file is a doc file i should store that file in some location say c:\file.doc.

What? you want to copy the file in a diff location? Just copy the file in a specified location using IO.File.Copy

seeism21-Jul-10 22:23

Hi,
I got the file in binary format from db.Now i want to save this file in some location given by the user by a file save as dialog option without opening it.

String new_FileName = Path.ChangeExtension(Path.GetTempFileName(), filetype);

File.WriteAllBytes(new_FileName, result);
FileDialog fldlg = new SaveFileDialog();
fldlg.InitialDirectory = "c:\\";// @" Big Grin | :-D

\";

fldlg.Filter = "*.jpg|*.gif|*.txt|*.doc|*.pdf|*.htm";
fldlg.FileName = filename;

This is my code.I did like this
But file is not saving

21-Jul-10 23:05

What exactly you are trying to do?
SaveFileDialog doesnt saves anything. It only shows the dialog box.

You need to use fldlg.ShowDialog to show dialog and ask user to select a filename.
Then you need to copy the file into its new location specified by user using system.IO.File.Copy(new_FileName, fldlg.FileName) or sort of.
