I've done a bit of searching on this subject and haven't found anything so far. I am successfully using the Profile object and am saving Profile records away into my SQL Server Database. I have checked using the stored procedures and viewed the individual records to know they are there. However, I want to create a WebForm that can enumerate through all of the users in my Membership DB (Same DB as the Profile DB) and list each user in a grid showing what values each user has within their profile. For example:
Username
Profile Element 1
Profile Element 2
Profile Element 3
bob
true
false
true
fred
true
false
true
I want however to replace the 'Profile Element 1' etc etc to display the actual name of the Profile. I would like to do this programmatically so I don't have to recompile the website everytime I add a new Profile element.
I have deployed my website to a shared hosting provider and since deployment, it shows the error "XML Parser Error:no element found" from time to time. I have checked my error log and I find issues such as "Object reference not set to an instance of the object" but the weird thing is if I visit the SAME page after a while, it loads!
I have checked with my hosting provider and they told me the below is what they can see on their side:
Exception information:
Exception type: HttpException
Exception message: Could not load type 'Test2.GlobalAsax'.
I have checked my global.asax and the interits are all correct. I have tried:
a) Deleting the webapplication dlls and rebuilding - didn't work
b) Deleting the global.asax and adding a new one and then rebuild. - didn't work
c) Changing the class name of global.asax.vb and updating at inherits at global.asax, and rebuild - didn't work
d) Change the Asp.Net version to an older version and change back to original version - didn't work
e) Debugged my application countless times locally (for the same page) but while connecting to the DB on my hosting provider - no issues found
My webhosting provider is saying there is an error in my code, but if there is a bug, shouldn't it always show the same error?
I also noticed that when the XML parser error is shown, if I were to go back to say Google.com and then to my website's main page, and then to the Page with error, the page loads!!
I am seriously running out of ideas what could have caused this issue. I have also conducted a ping test to my website and I am getting some time outs, will that cause my page to not load from time to time?
I'm looking at an asp.net application, i notice that there are assemblies defined into two places. In web.config there is configuration/system.web/compilation/assemblies/add elements. In the project file there are references setup under the Project/ItemGroup/Reference elements.
I was wondering, what is the difference between assemblies/references added in either location?
Is there a way to retrieve values from the form object using the id element instead of the name element?
View 3 RepliesI have a table in ASP.Net like this.
[code]....
I want to give border line to first td element which contains the colspan and rowspan. Not to the entire row.
I have noticed that when I create a website in a network drive and use the Ajax toolkit I get :
Element 'ToolkitScriptManager' is not a known element
I also noticed that after adding the ToolkitScriptManager it doesn't add the ID in the source code, it looks like this:
<asp:ToolkitScriptManager runat="server"></asp:ToolkisScriptManager>
Is missing the ID="ToolkitScriptManager1" part.
This doesn't happen when I create the site in my local drive. Is there a workaround to this. Even if I add the missing parts, I keep getting the same error.
I would like to select an element that is in the same TR as another element I found with a selector. The selector itself: $("input[name='sMessageValue']","#messageTable") Now I have this element and got its value I would like to find a checkbox located in the same TR, i tried this as starting point : $(this).(':parent').val(). But seems not the right thing to do.
View 9 RepliesYou're making a website with ASP.NET 4.0/C#, although xml alone is suitable for this example. The site will have a site map and a default page with a menu control, as follows:Web.sitemap
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="~/default.aspx" title="Home" description="">
<siteMapNode url="~/1.aspx" title="Link 1" description="" />
<siteMapNode url="~/2.aspx" title="Link 2" description="" />
<siteMapNode url="~/3.aspx" title="Link 3" description="" />

Element 'content' is not a known element. this can occur if there is a compilation error in the website, or the web.config file is missing.
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Content --- showed a green wavy line , and on hover displayed the above error.
Now I am having certain problems.
1. Visual Studio 2010 hangs when I try to use ToolBox.
2. Intellisense for asp.net controls is not working.
I have tried replacing web.config file (frm backup) , tried to debug - it doesnt show anything.
All other websites are working alright. Have problem with only one of the websites.
I upgraded from VS 2008 to VS 2010 and now the AJAX elements are not recognised by the source code editor, e.g. UpdatePanel, ScriptManager, etc. I get warnings in VS and no intellisense for those elements. When I run the site, all the AJAX controls work OK though.
View 6 RepliesI got this errors while trying to use an example from the ASP.NET 3.5 Unleashed book.
Webform1.aspx
[Code]....
LengthValidator.cs

As from the book's note, I think I added this line correctly:

However, the compiler kept complaining that:
Warning 1 Element 'LengthValidator' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing. C:Visual Studio 2010 ASP.NET ProjectsWebApplicationFourWebApplicationFourWebForm1.aspx 16 17 WebApplicationFour
I am using dotnetCHARTING: the dll is installed in the GAC and referenced in my web.config (all versions appear to match). The project has a reference to the dll.
web.config:
<add assembly="dotnetCHARTING, Version=5.3.3540.17054, Culture=neutral, PublicKeyToken=af2cd47db69d93bd"/>
The site code compiles ok, but all aspx pages using the charting library complain that the Chart tag does not exist (warning that it might be a compile error). The aspx pages do not render the charts.
Each page has a reference to the assembly:
<%@ Register Assembly="dotnetCHARTING" Namespace="dotnetCHARTING" TagPrefix="dotnetCHARTING" %>
What does that means below warning:
Element 'AsyncPostBackTrigger' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.
My app is working properly but visual studio showing warning like that.
Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site.
Element 'UpdatePanel' is not a known element. This can occur if there is a compilation error in the Web site.
tried many thingschecked web config filereinstalled ajaxtoolkit
but nothing is working
getting error in the whole projectalong with this getting error for other asp,net controls also
Element 'TextBox' is not a known element. This can occur if there is a compilation error in the Web site.
This may be something simple, but I am completely new to ASP.NET. I have been reading some tutorials based on W3Schools, and I have copied one of the files and tried to play with it by changing an element with a value to storing that same value in the attribute. Here is the edited XML (my.xml):
<?xml version="1.0" encoding="ISO-8859-1"?>
<countries>
<country>
<text value="N">Norway</text>
</country>
<country>
<text value="S">Sweden</text>
</country>
</countries>
I want to extract the N and S and use them as tooltips. Here is my aspx file:
<%@ Import Namespace="System.Data" %>
<script runat="server">
sub Page_Load
if Not Page.IsPostBack then
dim mycdcatalog=New DataSet
my.ReadXml(MapPath("my.xml"))
my.DataSource=my
my.DataBind()
end if
end sub
</script>

What have I missed here?
Is there a reliable way to extract text from PDF? The first thought that comes to mind is that PDF may have multiple columns and the extraction mechanism needs to know the logical structure somehow. I understand that some PDF docs are "tagged" but I'd need to support pretty much any PDF document.
Any third party components to the rescue here?
public void ZipExtract(Stream inputStream, string outputDirectory)
{
using (ZipFile zip = ZipFile.Read(inputStream))
{
Directory.CreateDirectory(outputDirectory);
zip.ExtractSelectedEntries("name=*.jpg,*.jpeg,*.png,*.gif,*.bmp", " ", outputDirectory,
ExtractExistingFileAction.OverwriteSilently);
[Code]....
I try to read zip archive from stream and extract files. Got the following exception in the line "using (ZipFile zip = ZipFile.Read(inputStream))" : ZipEntry::ReadDirEntry(): Bad signature (0xC618F879) at position 0x0000EE19. how to handle this exception?
I found an application that interacts with one of googles APIs that sends requests to the API and returns results to the web page. The owner of this app has made it publicly available and even though it is hosted on his server, it acts directly with the api from anyones browser. The source code in page source is available but since I dont know javascript, it is meaningless to me.
I would like to create an app that calls this web app and have it send requests to the API, and have the results parsed to a database. Would this be possible?
I have very little ASP experience and since trying to work through accessing the API itself is complicated since it involves using oAuth protocol and I am having a hard time with this with not much sample code available.
If this is possible, how can I get access to the results from this web app?
How can i extract title,header of a web page directly from the internet??
View 3 RepliesEvery morning we get a few hundred emails from our various customers servers that tell us how their backup went that previous night. Somebody has to go through these and fill out an excel spread sheet. I would like to automate this, we have our own server running a .NET application so i can schedule something every morning.
There are two main parts. The first is i want to know how to create a table that has customers down the left and dates accross the right, they are called pivot tables in access but not sure how to recreate them in MSSQL and to do it on the fly as i dont want to have to sit there entering 100's of days at a time.
The second is that differnt customers use differnt backup solutions, so i want to write some code that scans a particular mailbox in exchange, looks for emails that have come in in the past 12 hours, look at the from email address and match that to one in the database, then according to the subject line it will be able to identify what type of backup solution it is, e.g. if it says "Backup Exec Job completd Sucessfully" it knows its backup exec and will look for a particular text (completed successfully, completed with exceptions, no media etc) and can insert that, or if its a differnet backup solution then go and look at a specific place in that email for it.
I have an HTML string like
<A HREF="/files/1234/mybook.b1">mybook.b1</A><br>11/24/2010 1:02 AM 991
I want to fetch only the date element from this string. i.e 11/24/2010 1:02 AM
I know i can do that using the substring method of string class but i need to implement a standard solution for this problem. i.e. fetch date from any html content if it contains a date element.
