problems displaying image in GridView

That's right, it's me again! For the third or fourth time around I'm trying to make this work... I want to display images in a Gridview, but I'm stuck at getting the images to display. The GridView shows only the image ID:s.My images are saved in the database as <Binary Data>. I'm using an aspx page as Image Handler that receives the binary data of the image from the database and writes it to a response stream (at least that's what the tutorial says I'm doing), and the I use an Image Control in Template field on GridView to call the handler. I've been following this tutorial, and also Mudassar Khans prevoius tutorials combined with other tutorials:http://www.aspsnippets.com/Articles/Display-images-from-SQL-Server-Database-in-ASP.Net-GridView-control.aspxThankful for help!Here's my code,Imagehandler: protected void Page_Load(object sender, EventArgs e) { if (Request.QueryString["ID"] != null) { string sql = "SELECT ImgData, ImgContType from" + " BildProd where id=@id"; String strConnString = System.Configuration.ConfigurationManager .ConnectionStrings["DBPejganConnectionString1"].ConnectionString; SqlCommand cmd = new SqlCommand(sql); cmd.Parameters.Add("@id", SqlDbType.Int).Value

Problems displaying xml file after publishing to production server


In my Visual Studio 2008 web site, I created a new folder named Reporting.  Then one of my web pages creates an xml file in this new folder when the user clicks a button.  The user then clicks another button and the xml file displays in the browser.  This all works fine on my development PC. 

But if I publish this web site to my production server, it does not work.  I get an error when I click the first button to create my xml file.  The error reads:

Could not find part of the path 'c:\windows\system32\inetsrv\Reporting\abc.xml'

What must I do so that this works on my development PC and also my production server?





Displaying SharePoint lists in Web Parts

When you create a built-in or custom list in Microsoft Windows SharePoint Services, Windows SharePoint Services creates a Web Part, a basic building block of a SharePoint site, to display that list. These Web Parts are called List View Web Parts. Windows SharePoint Services stores List View Web Parts in the site collection Web Part gallery. (The site collection Web Part gallery is the most central gallery of Web Parts for a work group. By default, the gallery name is the name of the site, such as "Our Team Site Web Part Gallery." )

Displaying Row Details Tooltip on GridView using JQuery

Continuing exploring JQuery! I decided to implement a feature to display some kind of details related to a row displayed on GridView. For example when displaying employees details on GridView some information might not fit in the GridView because it will make it huge and wide. These infomration can be diplayed as Tooltip. Or when you want to display a picture and some kind of formated text to be diplayed as tooltip when mouse hover on the image.

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

form feild hints are not displaying for textboxses inside create user wizard?



I'm using following JS code to display input hint box besides the textbox whenever that asp.net textbox receives focus. 

I'm doing this for a registration form and all of the textboxes are inside the asp.net create user wizard control.

<script type="text/javascript">
function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;
  } else {
    window.onload = function() {

function prepareInputsForHints() {
	var inputs = document.getElementsByTagName("TextBox");
	for (var i=0; i<inputs.length; i++){
		// test to see if the hint span exists first
		if (inputs[i].parentNode.getElementsByTagName("span")[0]) {
			// the span exists!  on focus, show the hint
			inputs[i].onfocus = function () {
				this.parentNode.getElementsByTagName("span")[0].style.display = "inline";
			// when the cursor moves away from the field, hide the hint
			inputs[i].onblur = function () {
				this.parentNode.getElementsByTagName("span")[0].style.display = "none";

Visual Studio 2008 Memory problems

Problems with Forms Authentication in DD 4 site


Hello,  I am seeing a strange problem with Forms Authentication in my DD site.   A user logs into and can view/edit/delete data all day, but when they execute a Custom Filter against data (for example , a control DynamicData/Filters/CustomerLastNameSearch.ascx ) then the site auth fails, and redirects to the log in screen.

in web.config I have

     <authentication mode="Forms">
            <forms name=".Star" loginUrl="~/Login.aspx" protection="All" defaultUrl="~/Default.aspx" path="/" timeout="43200" cookieless="UseCookies" />     

Offhand, I am thinking two things : that DynamicData/Filters path requires some special handling for some reason, or the control extension ascx is causing auth to get confused.   Has anyone else experienced this or have any suggestions?  Thanks!

connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly.


I dont have the SQL EXPRESS installed instead I have SQL Standard Edition.

 I have two SQL Server instances installed.

 1- UserLT (this is sql 2000)
2- UserLT\SQL2005 (this is SQL 2005 named instance)

But when i try to add a database to my VS website project I get the following error:

Connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly. please verify the installation of the component or download from the URL: go.microsoft.com/fwlink/?linkId=4925

I went in Tools>Opetions>DataBase tools>Data Connection>Sql Server Instance Name (blank for default)

and changed the "SQLEXPRESS" to "USERLT\SQL2005".

But I still get the same error message. Any ideas how i can resolve this issue?

Problems posting to a package


Hey Y'all

I'm currently creating a program that accesses a mysql package to add data to a few tables.  I'm currently getting an error that says  "

ORA-01403: no data found
ORA-06512: at "JESSE.PKG_WORKPLAN", line 42
ORA-06512: at "JESSE.PKG_WORKPLAN", line 177
ORA-06512: at line 1


These lines are


and 177:add_team_members(V_PROJECT_ID, V_START_DATE, v_FISC_YEAR, V_MEMBERS ,V_NUM_MEMBERS,'add');

Checking these variables in my asp.net page they are all receiving parameters.

Is there a  way to see what the database is actually receiving from the asp.net page?

Or is there another thing to be looking at?


Public Shared function doubt????

I am using VB.net/ASP.NET and SQL Server 2000 for a web application.

For populating the dropdowns, I wrote a Public Shared function LoadDDL(), in which I pass the dataset and dropdown name to set.

I have my doubts that this function will produce unexpected results for concurrent users. And will mix the results among sessions because it is a Shared function.

I am confused here. Is it the right way to go?

Please advice. Thanks in advance.


URL Routing and Existing HttpHandler problems


Hello everyone,

I have a problem:

I am currently using 2 features: 

1. HttpHandler

Registering the path="res.aspx" verb="*"

2. URL Routing:

Registering with this pattern: "Company/Edit/{*companyId}","~/CompanyEdit.aspx"

In my CompanyEdit.aspx page, I used httphandler res.aspx to generate some images at client.

  • res.aspx?img=1
  • res.aspx?img=3

Now the problem is here, the page is load success with companyId = "12345", but when the images was loaded at client, it loaded the CompanyEdit.aspx again and show error with wrong id.  

I have debug and find the problem that because when image's urls were generated to client with url=res.aspx?img=1, url=res.aspx?img=3, the asp.net will understand that they are Company/Edit/res.aspx?img=1, Company/Edit/res.aspx?img=3 when it maps with URL Routing pattern.

=> So the CompanyEdit.aspx was load again with wrong id (id now is "res.aspx"). 

So, do you have any ideas to solve this problem, or other design.

Thanks, and best regard
