Hide console window in console application
As you all know when you execute an console application it will load command prompt and shows out put. There are amny situation in which you do not want this console window to be dislayed to user while your application runing. You can do that by calling some unmanaged functions. I have used following method to do that which is posted by
Brendan Grant on MSDN
Raise event from user control to main page / Event delegation from user control to aspx page in ASP.NET,C#
"What is delegate?" we all have faced this question in one or more interview. :) and the most common answer is "Function pointer". Here I am showing a simple example of delegate. I have one user control and one aspx page. The user control contains one button. When user click on this button I will call a method on main page using delegate. Here is my user control,
<%@
Control
Language="C#"
AutoEventWireup="true"
CodeFile="WebUserControl.ascx.cs"
Inherits="Dalegate_WebUserControl"
%>
<asp:Button
ID="btnTest"
runat="server"
Text="I
am Inside User Control" OnClick="btnTest_Click"
/>
public partial
class
Dalegate_WebUserControl : System.Web.UI.UserControl
{
// Delegate declaration
public
delegate
void
OnButtonClick(string
strValue);
// Event declaration
public
event
OnButtonClick btnHandler;
// Page load
protected
void Page_Load(object
sender, EventArgs e)
{
}
protected
void btnTest_Click(object
sender, EventArgs e)
{
// Check if event is null
if (btnHandler !=
null)
btnHandler(string.Empty);
// Write some text to output
Response.Write("User
Control's Button Click <BR/>");
}
}
WebUserControl.ascx.cs
Above code first check
whether btnHandler is not null and than raise the event by passing argument. You
can pass any number of argument in event. You need to change
public
delegate
void
OnButtonClick(string
strValue) and btnHandler(string.Empty)
lines for changing number of arguments. Now take a look at aspx page,
<%@ Page
Language="C#"
AutoEventWireup="true"
CodeFile="Default.aspx.cs"
Inherits="Dalegate_Default"
%>
<%@ Register
Src="WebUserControl.ascx"
TagName="WebUserControl"
TagPrefix="uc1"
%>

</html>
Default.aspx
Default.aspx has one drop down list
and a user control as shown in above code. Lets look at cs file,
public partial
class
Dalegate_Default : System.Web.UI.Page
{
protected
void Page_Load(object
sender, EventArgs e)
{
// Declare and Define Event of User Control. When
User
// Clicks
on button (which is inside UserControl)
// below event is raised as I have called raised
that
// event
on Button Click
WebUserControl1.btnHandler += new
Dalegate_WebUserControl.OnButtonClick
(WebUserControl1_btnHandler);
}
void WebUserControl1_btnHandler(string
strValue)
{
Response.Write("Main
Page Event<BR/>Selected
Value: " + ddlTemp.SelectedItem.Text +
"<BR/>");
}
}
Default.aspx.cs
Now when you run the application and clicks on button you can see that when user click on button the user control raise the click event and calls the WebUserControl1_btnHandler(string strValue) method on main page.

Normally, you only options for displaying a background
bitmap are tiled, centered, or stretch to fit (with the Plus Pack).
You can edit the registry and have a third option which is to place the bitmap anywhere on your screen by specifying the X and Y coordinates.
You can edit the registry and have a third option which is to place the bitmap anywhere on your screen by specifying the X and Y coordinates.
- Start Regedit
- Go to HKEY_CURRENT_USER / Control Panel / Desktop
- Create new Strings called WallpaperOriginX and WallpaperOriginY
- Give them values to position them around your desktop
- The bitmap must be smaller than your desktop size
Expanding All Subfolders in Explorer
To quickly have Explorer expand all subfolders for a selected drive or folder, simply press the asterisk (*) key on the numeric keypad.
Opening a Command Prompt to a Particular Directory from Explorer
If you want to open a command prompt to a directory that is selected in the Explorer:
- Start Regedit
- Go to HKEY_CLASSES_ROOT \ Directory \ shell
- Create a new key called Command
- Give it the value of the name you want to appear in the Explorer. Something like Open DOS Box
- Under this create a new key called command
- Give it a value of " cmd.exe cd %1 " (no quotes)
- Now when you are in the Explorer, right click on a folder, select Open DOS Box, and a command prompt will open to the selected directory.
String/Number format
Strings
There really isn't any formatting within a strong, beyond it's alignment. Alignment works for any argument being printed in a String.Format call.| Sample | Generates |
| String.Format("->{1,10}<-", "Hello"); | -> Hello<- |
| String.Format("->{1,-10}<-", "Hello"); | ->Hello <- |
Numbers
Basic number formatting specifiers:| Specifier | Type | Format | Output (Passed Double 1.42) | Output (Passed Int -12400) |
| c | Currency | {0:c} | $1.42 | -$12,400 |
| d | Decimal (Whole number) | {0:d} | System.FormatException | -12400 |
| e | Scientific | {0:e} | 1.420000e+000 | -1.240000e+004 |
| f | Fixed point | {0:f} | 1.42 | -12400.00 |
| g | General | {0:g} | 1.42 | -12400 |
| n | Number with commas for thousands | {0:n} | 1.42 | -12,400 |
| r | Round trippable | {0:r} | 1.42 | System.FormatException |
| x | Hexadecimal | {0:x4} | System.FormatException | cf90 |
Custom number formatting:
| Specifier | Type | Example | Output (Passed Double 1500.42) | Note |
| 0 | Zero placeholder | {0:00.0000} | 1500.4200 | Pads with zeroes. |
| # | Digit placeholder | {0:(#).##} | (1500).42 | |
| . | Decimal point | {0:0.0} | 1500.4 | |
| , | Thousand separator | {0:0,0} | 1,500 | Must be between two zeroes. |
| ,. | Number scaling | {0:0,.} | 2 | Comma adjacent to Period scales by 1000. |
| % | Percent | {0:0%} | 150042% | Multiplies by 100, adds % sign. |
| e | Exponent placeholder | {0:00e+0} | 15e+2 | Many exponent formats available. |
| ; | Group separator | see below |
The group separator is especially useful for formatting currency values which require that negative values be enclosed in parentheses. This currency formatting example at the bottom of this document makes it obvious:
Dates
Note that date formatting is especially dependant on the system's regional settings; the example strings here are from my local locale.
| Specifier | Type | Example (Passed System.DateTime.Now) |
| d | Short date | 10/12/2002 |
| D | Long date | December 10, 2002 |
| t | Short time | 10:11 PM |
| T | Long time | 10:11:29 PM |
| f | Full date & time | December 10, 2002 10:11 PM |
| F | Full date & time (long) | December 10, 2002 10:11:29 PM |
| g | Default date & time | 10/12/2002 10:11 PM |
| G | Default date & time (long) | 10/12/2002 10:11:29 PM |
| M | Month day pattern | December 10 |
| r | RFC1123 date string | Tue, 10 Dec 2002 22:11:29 GMT |
| s | Sortable date string | 2002-12-10T22:11:29 |
| u | Universal sortable, local time | 2002-12-10 22:13:50Z |
| U | Universal sortable, GMT | December 11, 2002 3:13:50 AM |
| Y | Year month pattern | December, 2002 |
The 'U' specifier seems broken; that string certainly isn't sortable.
Custom date formatting:
| Specifier | Type | Example | Example Output |
| dd | Day | {0:dd} | 10 |
| ddd | Day name | {0:ddd} | Tue |
| dddd | Full day name | {0:dddd} | Tuesday |
| f, ff, ... | Second fractions | {0:fff} | 932 |
| gg, ... | Era | {0:gg} | A.D. |
| hh | 2 digit hour | {0:hh} | 10 |
| HH | 2 digit hour, 24hr format | {0:HH} | 22 |
| mm | Minute 00-59 | {0:mm} | 38 |
| MM | Month 01-12 | {0:MM} | 12 |
| MMM | Month abbreviation | {0:MMM} | Dec |
| MMMM | Full month name | {0:MMMM} | December |
| ss | Seconds 00-59 | {0:ss} | 46 |
| tt | AM or PM | {0:tt} | PM |
| yy | Year, 2 digits | {0:yy} | 02 |
| yyyy | Year | {0:yyyy} | 2002 |
| zz | Timezone offset, 2 digits | {0:zz} | -05 |
| zzz | Full timezone offset | {0:zzz} | -05:00 |
| : | Separator | {0:hh:mm:ss} | 10:43:20 |
| / | Separator | {0:dd/mm/yyyy} | 10/12/2002 |
Enumerations
| Specifier | Type |
| g | Default (Flag names if available, otherwise decimal) |
| f | Flags always |
| d | Integer always |
| x | Eight digit hex. |
Some Useful Examples
String.Format("{0:$#,##0.00;($#,##0.00);Zero}", value);
This will output "$1,240.00" if passed 1243.50. It will output the same format but in parentheses if the number is negative, and will output the string "Zero" if the number is zero.
String.Format("{0:(###) ###-####}", 18005551212);
This will output "(800) 555-1212".
Add new item to dropdownlist
Add new options to the exisitng dropdown lsit

Sys types
"Type" columns of SysObjects table represent the different objects available in database (like Table,Trigger,Stored Procedures etc.). Below list explains the different values of "Type" columns.
C = CHECK constraint D = Default or DEFAULT constraint F = FOREIGN KEY constraint FN = Scalar function IF = Inlined table-function K = PRIMARY KEY or UNIQUE constraint L = Log P = Stored procedure R = Rule RF = Replication filter stored procedure S = System table TF = Table function TR = Trigger U = User table V = View X = Extended stored procedure
How to Encrypt web.config
The most sensitive information stored in web.config file can be the connection string. You do not want to disclose the information related to your database to all the users where the application is deployed. Every time it is not possible to have a private machine for your sites, you may need to deploy the site in shared host environment. To encrypt the connection string in above situation is advisable.
ASP.NET 2.0 provides in built functionality to encrypt few sections of web.config file. The task can be completed using Aspnet_regiis.exe.
Encryption:
For File System Application
aspnet_regiis.exe -pef "connectionStrings" C:\Projects\DemoApplication
For IIS based Application
aspnet_regiis.exe -pe "connectionStrings" -app "/DemoApplication"
Decryption:
For File System Application,
aspnet_regiis.exe -pdf "connectionStrings" C:\Projects\DemoApplication
For IIS based Application
aspnet_regiis.exe -pd "connectionStrings" -app "/DemoApplication"

Tooltip
First, add the following CSS to those pages that use the rich tooltips:
.skmTooltipHost
{
cursor: help;
border-bottom: dotted 1px brown;
}
.skmTooltipContainer
{
padding-left: 10px;
padding-right: 10px;
padding-top: 3px;
padding-bottom: 3px;
display: none;
position: absolute;
background-color: #ff9;
border: solid 1px #333;
z-index: 999;
}
Next, add the following function to your page
<script type="text/javascript">
$(document).ready(function() {
$(".skmTooltipHost").hover(
function() {
$(this).append('<div class="skmTooltipContainer">' + $(this).attr('tooltip') + '</div>');
$(this).find('.skmTooltipContainer').css("left", $(this).position().left + 20);
$(this).find('.skmTooltipContainer').css("top", $(this).position().top + $(this).height());
$(".skmTooltipContainer").fadeIn(500);
},
function() {
$(".skmTooltipContainer").fadeTo(500, 1.0, function() { $(this).remove(); });
}
);
});
</script>
Finally copy the lines
<p> This example shows how to use jQuery and a touch of CSS to display rich <span class="skmTooltipHost" tooltip="Dictionary.com defines <a href="http://dictionary.reference.com/browse/tooltip">tooltip</a> as, "a small rectangular pop-up window that displays a brief description of a toolbar button when a computer mouse lands on that button."">tooltips</span> when hovering over an HTML element. </p>
