Viagra 50mg Pills $81.00

Viagra directions I was rolling along one night, viagra directions tired but making good progress, viagra directions when one of my DropDownLists refused to fire its OnSelectedIndexChanged event.

Viagra directions During the postback, viagra directions Page_Load fired, viagra directions but the OnSelectedIndexChanged event for the control did not.

Viagra directions After some time, viagra directions I finally realized that the VALUES of the ill-behaving DropDownList were all the empty string (“”) because I had forgotten to make the key column of the table supplying the list data an IDENTITY column in SQL Server. Viagra directions So even though the selected INDEX was changing, viagra directions the selected VALUE was not. Viagra directions It was always “”, viagra directions because the keys were NULL in SQL Server.

Viagra directions My point here is that had Microsoft named the event better — or fixed it so that it is fired when its name says it will be — the confusion could have been avoided.

Viagra directions Be forewarned: The selected index in a DropDownList can change all it wants, viagra directions but unless the underlying value changes the control’s SelectedIndexChanged event will not be fired.

Koluba.up2.co.il order viagra The jQueryUI sortable widget works like magic. Koluba.up2.co.il order viagra Apply it to an HTML DIV that contains other DIVs and you can magically drag and drop the inner DIVs to reorder them on the client. Koluba.up2.co.il order viagra Say, koluba.up2.co.il order viagra for example, koluba.up2.co.il order viagra you have an image gallery and want to allow the site administrator to reorder the images. Koluba.up2.co.il order viagra Drop the images into the inner DIVs, koluba.up2.co.il order viagra attach the widget to the outer DIV and you’re done.

Koluba.up2.co.il order viagra Here’s how:

Koluba.up2.co.il order viagra 1. Koluba.up2.co.il order viagra Add jQuery files

Koluba.up2.co.il order viagra <script type=”text/javascript” src=”//code.jquery.com/jquery-2.1.1.min.js” ></script>

Koluba.up2.co.il order viagra <script type=”text/javascript” src=”//code.jquery.com/ui/1.10.4/jquery-ui.min.js” ></script>

Koluba.up2.co.il order viagra <link rel=”stylesheet” href=”//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css” />

Koluba.up2.co.il order viagra 2. Koluba.up2.co.il order viagra Insert startup scripts to make the outer DIV with the ID “sortable” sortable

Koluba.up2.co.il order viagra <script>

Koluba.up2.co.il order viagra $(function () {

$(“#sortable”).sortable();

}

Koluba.up2.co.il order viagra </script>

Koluba.up2.co.il order viagra 3. Koluba.up2.co.il order viagra Create the div with the sortable ID. Koluba.up2.co.il order viagra Put the inner divs inside it.

Koluba.up2.co.il order viagra <div id=”sortable” >

Koluba.up2.co.il order viagra <div style=”height:200px;”>
<img id=”ctl00_ContentPlaceHolder1_RIL1_Repeater1_ctl00_Image1″ ImageID=”50″ src=”http://www.mysite.com/donuts.jpg” style=”height:200px;border-width:0px;” />
<input type=”hidden” name=”ids” id=”ids” value=’50′ />
</div>

Koluba.up2.co.il order viagra <div style=”height:200px;”>
<img id=”ctl00_ContentPlaceHolder1_RIL1_Repeater1_ctl01_Image1″ ImageID=”48″ src=”http://www.mysite.com/BMproduce.jpg” style=”height:200px;border-width:0px;” />
<input type=”hidden” name=”ids” id=”ids” value=’48′ />
</div>
… and so on

Koluba.up2.co.il order viagra </div> <!– end id=sortable –>

Koluba.up2.co.il order viagra The thing to notice here is that, koluba.up2.co.il order viagra instead of trying to use the widget’s fancy UPDATE event to trigger a javascript routine charged with reporting the new image order back to the server, koluba.up2.co.il order viagra perhaps via AJAX, koluba.up2.co.il order viagra we instead include in each list element a hidden input field containing the id of the element to be reordered. Koluba.up2.co.il order viagra When a list item gets dragged to a new position, koluba.up2.co.il order viagra this hidden field gets dragged along with it.

Koluba.up2.co.il order viagra Finally, koluba.up2.co.il order viagra we give all of these hidden fields the same name: ids. Koluba.up2.co.il order viagra When the form is posted back, koluba.up2.co.il order viagra the form field named ids contains the keys in order, koluba.up2.co.il order viagra like this:

Koluba.up2.co.il order viagra ids=23, koluba.up2.co.il order viagra43, koluba.up2.co.il order viagra54, koluba.up2.co.il order viagra67, koluba.up2.co.il order viagra65, koluba.up2.co.il order viagra87, koluba.up2.co.il order viagra67

Koluba.up2.co.il order viagra Given these record keys, koluba.up2.co.il order viagra of course, koluba.up2.co.il order viagra you can just create SQL statements to update each record’s “SEQ” value. Koluba.up2.co.il order viagra In other words, koluba.up2.co.il order viagra set the SEQ of record 23 to 1, koluba.up2.co.il order viagra set the SEQ of record 43 to 2 and so on.

Koluba.up2.co.il order viagra Simple!

Buy cialis fedex shipping WARNING: This technique, buy cialis fedex shipping sadly, buy cialis fedex shipping only works in Full trust mode. Buy cialis fedex shipping Most shared servers use medium trust. Buy cialis fedex shipping If you’re one of those, buy cialis fedex shipping you’ll have to use the old URLRewrite module, buy cialis fedex shipping which should be pre-installed for you by your hosting company.

Buy cialis fedex shipping Finally, buy cialis fedex shipping Microsoft has come up with a version of Friendly URLs that is friendly to programmers, buy cialis fedex shipping too. Buy cialis fedex shipping Nonetheless, buy cialis fedex shipping there are a few things you need to be aware of.

Buy cialis fedex shipping First, buy cialis fedex shipping the Microsoft.aspnet.FriendlyUrls assembly follows the standard “forward slash” model. Buy cialis fedex shipping So URLs look like this: //www.mydomain.com/documents/2013/01

Buy cialis fedex shipping When parsing the URL, buy cialis fedex shipping the module starts from the right and searches for a file name that when stripped of its .aspx extension matches the segment. Buy cialis fedex shipping For example, buy cialis fedex shipping say you have a documents.aspx page in the root folder. Buy cialis fedex shipping If the URL //www.mydomain.com/documents/2013/01 is submitted, buy cialis fedex shipping the module first tries to find “01.aspx” in the “documents/2013″ folder. Buy cialis fedex shipping Not finding it, buy cialis fedex shipping it assumes “01″ is data. Buy cialis fedex shipping Next, buy cialis fedex shipping it moves to “2013″ and also does not find a page called 2013.aspx in the “documents” folder, buy cialis fedex shipping so it assumes “2013″ is data as well. Buy cialis fedex shipping Finally it gets to “documents”, buy cialis fedex shipping finds documents.aspx in the root folder, buy cialis fedex shipping and executes it.

Buy cialis fedex shipping Installing the Microsoft.aspnet.FriendlyUrls module extends the regular Request object with several new objects. Buy cialis fedex shipping One of these is the zero-based GetFriendlyUrlSegments array, buy cialis fedex shipping which contains each of the URL segments that follow the segment that matched the ASPX page. Buy cialis fedex shipping In our example, buy cialis fedex shipping Request.GetFriendlyUrlSegments(0) would return the string “2013″ and GetFriendlyUrlSegments(1) would return “01″.

Buy cialis fedex shipping That’s great so far, buy cialis fedex shipping but unfortunately ASP.NET assumes that the last segment of the URL is the script name, buy cialis fedex shipping and so sets the form’s action property to it. Buy cialis fedex shipping In our test case, buy cialis fedex shipping the action would be “01″. Buy cialis fedex shipping Submitting the form causes an error, buy cialis fedex shipping because there’s no “01.aspx” file in the root folder.

Buy cialis fedex shipping One solution to the problem is to simply update the form’s action property to match your entire friendly URL, buy cialis fedex shipping and not just the tail end of it. Buy cialis fedex shipping To do this, buy cialis fedex shipping add an OnPrerender sub to the page (or master page) and add this line to it:

Buy cialis fedex shipping form1.Action = Request.CurrentExecutionFilePath

Buy cialis fedex shipping CurrentExecuteFilePath is defined as “the virtual path to the current request.” In our case, buy cialis fedex shipping it’s the entire string “/documents/2013/01″.

Buy cialis fedex shipping Now the form posts back to itself, buy cialis fedex shipping as it should.

Buy cialis fedex shipping By the way, buy cialis fedex shipping after you install the Microsoft.aspnet.FriendlyURLs package, buy cialis fedex shipping your web site should:

Buy cialis fedex shipping 1. Buy cialis fedex shipping Have the following files added to the bin folder

Buy cialis fedex shipping /bin/Microsoft.AspNet.FriendlyUrls.dll

Buy cialis fedex shipping /bin/Microsoft.AspNet.FriendlyUrls.dll.refresh

Buy cialis fedex shipping /bin/Microsoft.AspNet.FriendlyUrls.xml

Buy cialis fedex shipping /bin/microsoft.web.infrastructure.dll

Buy cialis fedex shipping /bin/microsoft.web.infrastructure.dll.refresh

Buy cialis fedex shipping 2. Buy cialis fedex shipping Have the following lines in web.config’s configuration/system.web/compilation/assemblies section

Buy cialis fedex shipping <add assembly=”Microsoft.Web.Infrastructure, buy cialis fedex shipping Version=1.0.0.0, buy cialis fedex shipping Culture=neutral, buy cialis fedex shipping PublicKeyToken=31BF3856AD364E35″/>
<add assembly=”System.Web.Routing, buy cialis fedex shipping Version=4.0.0.0, buy cialis fedex shipping Culture=neutral, buy cialis fedex shipping PublicKeyToken=31BF3856AD364E35″/>

Buy cialis fedex shipping You can have Visual Studio insert these lines by adding a reference to the ddl files in /bin. Buy cialis fedex shipping (WEBSITE/Add Reference)

Buy cialis fedex shipping 3. Buy cialis fedex shipping Include the assembly in all code pages that use the extensions to the Request object, buy cialis fedex shipping

Buy cialis fedex shipping Imports Microsoft.AspNet.FriendlyUrls

Buy cialis fedex shipping 4. Buy cialis fedex shipping The global.asax file should “turn on” friendly urls by adding references to the assemblies and calling “EnableFriendlyUrls.”

Buy cialis fedex shipping <%@ Import Namespace=”System.Web.Routing” %>
<%@ Import Namespace=”Microsoft.Aspnet.FriendlyUrls” %>

Buy cialis fedex shipping <%@ Application Language=”VB” %>

Buy cialis fedex shipping <script runat=”server”>
Sub Application_Start(ByVal sender As Object, buy cialis fedex shipping ByVal e As EventArgs)

Buy cialis fedex shipping         ‘ Code that runs on application startup

Buy cialis fedex shipping         RouteTable.Routes.EnableFriendlyUrls()

Buy cialis fedex shipping end sub

Buy cialis fedex shipping (… and so on)

Women Use Viagra

by Lynn Demarest in SQL Server, Technical

Cialis headaches UPDATE: I learned today that you can sometimes open .DBF files with Excel. Cialis headaches If you can do this, cialis headaches it will be easier than the method described below. Cialis headaches Simply open the .DBF file, cialis headaches then save it as a .CSV and import the .CSV into SQL Server.

Cialis headaches  

Cialis headaches I received a .DBF file the other day that contained a bunch of data in which I was interested. Cialis headaches I don’t have DBase anymore (who does?) so I wanted to import the data into MS SQL Server so I could write queries against it.  But how to accomplish such an import? There’s no option to import a .DBF file directly.

Cialis headaches The solution was ODBC. Cialis headaches Here’s how to do it:

1. Cialis headaches Create an ODBC connection to the .DBF file

  1. Find Data Sources (ODBC) in the Control Panel‘s Administrative Tools.
  2. Select the System DSN tab and click Add
  3. Select Microsoft DBase Driver (*.dbf)
  4. Click Finish
  5. Enter a Data Source Name (no spaces)
  6. Un-check Use Current Directory
  7. Click the Select Directory button and navigate to the folder that contains the .DBF file

Cialis headaches Your  .DBF file is now ready to be accessed via ODBC.

2. Cialis headaches Import the .DBF data into SQL Server

  1. Open Microsoft SQL Server Management Studio and create a new database
  2. Right-click the database name, cialis headaches select tasks and import data.
  3. The welcome screen will open. Cialis headaches Click Next.
  4. Select the data source
    Because we’re moving data into SQL Server from .DBF, cialis headaches the .DBF file is our source.
    Select .Net Framework Data Provider for Odbc
  5. In the Dsn area, cialis headaches enter the DSN (data source name) you just created.
  6. Enter ODBC for the Driver. Cialis headaches (The ConnectionString should be created for you.)
  7. Choose the destination SQL Server. Cialis headaches (This should already be the database you set in step 2, cialis headaches above.)
  8. You will only be able to select Write a query to specify the data to transfer. Cialis headaches Click Next.
  9. Your query is select * from [filename.dbf] where [filename.dbf] is the name of the file the ODBC connection points at. Cialis headaches (Do NOT enter the brackets!)
  10. Change the name of the destination table so that it makes sense. Cialis headaches It will default to “Query”
  11. Click Finish to execute the data transfer
