How to get a .Net Control of a web page in c#

Thats by default. Do one thing, dont maximize the child form so as to prevent the parent MDI from maximizing.

Uhm forgive me if I'm wrong, I have not worked with MDI for 15 years, but isn't an MDI main form a container for child forms and as such has to "contain" the child. Is it possible to drag a child form outside an MDI container these days. If this is the case then your question is a really dumb one.

Hi, In my database table i have column with data like

00987
78960
89760
08123
009876

when i read the value(00987) into the integer variable, then it contiana value as 987.

I need the value in integer variable as same(00987). How can i do this?

int k = Convert.ToInt16(dt.rows[i]["colname]);

00987 is the same as 987. If you read it into an integer variable, then it will remove leading zeros. If you want to display it as it is in the database, then convert it to a string instead of an integer

This data is stored as a string in your database. 00987 is exactly the same as 987 - I assume you want it displaying as 00987; in which case you need to use a string to display it.

You have to do nothing (or just review your basic math course material), since 000987 = 987 holds for a integer.

I suppose that what you really wanted to ask is: how to read a data with leading zeros and don't loose these zeros.
You have two possibilities:
- Store the number asa string in your application and parse it each time you need it for calculations.
- Create a structure which would store a number of zeros (I would do it this way).

internal struct IntWithZeros
{
	private int zerosCount, value;

	public static implicit operator int(IntWithZeros x)
	{
		return x.value;
	}

	// overload other required operators to preserve zerosCount

	public static IntWithZeros Parse(string data)
	{
		IntWithZeros ret;
		ret.zerosCount = 0;
		while (data.Length > ret.zerosCount && data[ret.zerosCount] == '0') {
			ret.zerosCount++;
		}
		ret.value = int.Parse(data);
		return ret;
	}
	public override string ToString()
	{
		string s = value.ToString();
		return s.PadLeft(s.Length + zerosCount, '0');
	}
}

Hi guys,

I had just posted a question about getting the path of the current executable. Thanks to all those who responded. However, I found this peice of code while googling just now, and this really seems to work:

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            System.Reflection.Assembly a = System.Reflection.Assembly.GetEntryAssembly();
            string baseDir = System.IO.Path.GetDirectoryName(a.Location);
            Console.WriteLine(baseDir);
            Console.ReadLine();
        }
    }
}

Here, Console.WriteLine(baseDir); prints the path of the .exe.

However, I want that the current executable be copied and moved using the System.IO; .NET class library namespace.

Some thing like this:

Instead of printing the path address with Console.WriteLine(baseDir);, I want to replace it with: System.IO.File.Copy("basedir", "C:\\desiredlocation");

But this code:

System.IO.File.Copy("basedir", "C:\\desiredlocation");

doesn't seem to work.

Can anyone help me out?

'basedir' shouldn't be in quotes. And that code snippet will copy the entire directory. Useful if you have references you want preserving, but if you just want to copy the executable, you should be specifying a.Location as the first parameter of File.Copy, not basedir

Hi Computa,

The case remains same though I apply a.Location as the first parameter of File.Copy method.

Throws exception.

Exception type:
IOException
Exception details:
The target file "C:\\DesiredLocation" is a directory not a file.

Anyway, let me explain the problem more clearly. All I want to do is to copy only the .exe file to C:\\DesiredLocation.

Lemme know, if I need to be more comprehensive.

$Shucks | :-\$ Try (new System.Uri(a.CodeBase)).AbsolutePath according to MSDN. This is because the CodeBase property is the fully escaped URL, including the file:// part. File.Copy won't accept this, so you need to create a new Uri, which parses it properly, and use the AbsolutePath property (which gets the proper name)

I assume that you want to move the file you have referenced in the baseDir variable to the new location - this means you shouldn't put quotes around baseDir in File.Copy, because that's a string literal, not a variable. Change it to

File.Copy(baseDir, @"c:\desiredlocation");

Hi Pete,

The code:

File.Copy(baseDir, @"c:\desiredlocation");

throws exception!

Exception type:
IOException
Exception Details:
The target file "C:\desiredlocation" is a diretory, not a file.

PS: I want to copy the exe file namely 'ConsoleApplication1.exe' to C:\desiredlocation and not he entire project.

Any ideas?

)
 
Parameters
sourceFileName
The file to copy. 

destFileName
The name of the destination file. This cannot be a directory or an existing file.
