What I'm trying to achieve is to track any change made on a form. I thought DataSet.HasChanges and DataSet.GetChanges would be a good way to accomplish this. However, in the code below DataSet.HasChanges always returns false.
EmployeeDs represents a strongly typed DataSet.how to get changes from the updated row into the new dataSet?
[Code]....
I don't understand how the stored procedure is returning false. It's supposed to continue looping and continue writing rows. Right now it writes the very first row, and then it goes into the If Not AdvanceLinkBanned.Add(banrec) Then and it goes in here, prints the message and exits the sub. Why is it thinking the add returns false? If Not AdvanceLinkBanned.Add(banrec) ? Doesn't this return the id of the new record? Isn't this not zero? Zero would make it false. How can this be false? Isn't it supposed to return the next record created ? Doesn't SELECT SCOPE_IDENTITY() return the value of the record id? How do I test this?

I added a new table to my type dataset. When the code tries to execute the new row on that table I get the error message.
(if you can't see the error. "MissingMethodException was caught" "Method not found: 'MyTableDataTable MyNamespace.get_SSCase().")
I've tried the wizard and also click and drag the table from solution explorer to the xsd file. The other tables work, just this one table won't work. What should I check?
I've an EntityCollection< T > which contains an element but the Contains method returns false.
I've overriden T's 'Equals' method but the 'Contains' method does not call it (while it's said so in documentation).
When I do foreach (T x in coll), x.Equals(element) returns true.
code:
contains(object entCol, object val)
{
var coll = (ICollection<GraphicSockets>)entCol;
var socket = val as GraphicSockets;
foreach (GraphicSockets sock in coll)
socket.Equals(sock); //true for first element, GraphicSocket's Equals function called
coll.Contains(socket);//false, Equals function not called}
the code i'd actually like to use is
private static bool contains(object entCol, object val)
{
Type entColType = typeof(EntityCollection<>).MakeGenericType(val.GetType());
MethodInfo contains = entColType.GetMethod("Contains");
return (bool)contains.Invoke(entCol, new object[] { val });
}
this worked once but stopped when i started using wcf, i wonder how this contains method works.....
I'm using a model which receives some input from a form and has some validation logic attached via attributes. In one case I'm validating personal names, which should include only letters, apostrophes, spaces and dashes, and be no more than 50 chars long. So I have a model property like:
[Code]....
Everything works fine BUT the RegularExpression attribute: if I add it, I always get a validation error, even when what I type in my form is a valid name (e.g. "Foo"). No matter how I modify the regular expression or what I type, I always get an invalid name error.
(For some reason, I cannot see the regex posted correctly here: it is just ^ followed by the Unicode Letter class and []+ including a Unicode letter class, apostrophe, whitespace and dash, ended by dollar: i.e. start of string - any letter - any of the following: letter, apostrophe, whitespace, dash, 1 or more times; end of string).
What I'm doing wrong here?
I've created a script that adds user data to a database, however, I'd like to check the email entered is unique within the database.
I've already started the query at comm2 but not sure how to progress the script so it tells the user if the email address is already taken.

I have a ListView control and under ItemTemplate I have following code:
Code:
<asp:Label ID="Label1" runat="server" Text='<% #MatchCategory(dtCategories.Rows[i]["ID"].ToString().Trim(), Eval("CategoryID").ToString()) %>'></asp:Label>
The MatchCategory method just checks if two values are equal and return true or false. Just below this code I am separately printing dtCategories.Rows[i]["ID"].ToString().Trim() and Eval("CategoryID")
acan see matching values but MatchCategory method always returns false.

I have some trouble using the openid check_authentication. The answer from the openid providers (I tried with google and myopenid) is always: is_valid:false I do already get the openid.sig and openid.identity but when I try to verify my data with the check_authentication call it always returns is_valid:false. What I have done so far (authentication with google openid in this example, but for myopenid it was the same): I redirect the web user from my page to the following: [URL]
(Without the line breaks of course, I put them in this post only to keep it readable. localhost:104/evalgoogle.aspx is my local test environment) I will then get redirected to the google login page where I can sign in and accept that I will login at Localhost. I unchecked the remember checkbox though. After logging in I will get redirected to the return_to page I set and get the following data in the request:
openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0
&openid.mode=id_res
&openid.op_endpoint=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fud
&openid.response_nonce=2010-02-12T14%3A46%3A52Z1PDyxBssEN9p5g
&openid.return_to=http%3A%2F%2Flocalhost%3A104%2Fevalgoogle.aspx
&openid.assoc_handle=AOQobUfpVnBFYzFO15z92rru88nWjEnw0u8ethVscpjDwkssp8GjVc0u
&openid.signed=op_endpoint%2Cclaimed_id%2Cidentity%2Creturn_to
%2Cresponse_nonce%2Cassoc_handle
&openid.sig=24Hetky5HrNwrY3%2B%2B2vtIGnvmnI%3D
&openid.identity=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fid%3Fid%3D{SOMEID}
&openid.claimed_id=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fid%3Fid%3D{SOMEID}
(where {SOMEID} is my google id) To verify this signature and google id, I composed a webrequest calling the check_authentication as described in openid.net/specs/openid-authentication-1_1.html#mode_check_authentication. My problem now is that this always returned is_valid:false To eliminate possible problems in my webrequest, I now create just a html form with the data I get back from google like this:
<form method="post" action="<%=Request.Params["openid.op_endpoint"] %>">
<div>
<input type="text" name="openid.mode" value="check_authentication" />
<input type="text" name="openid.assoc_handle" value="<
%=Request.Params["openid.assoc_handle"] %>" />
" />
" />
" />
" />
" />
" />
But this also just yields the is_valid:false
We have just migrated our application from VS 2008 to VS 2010 and our database from Sql server 2005 to 2008. Everything was working great until i tried to login to the site.
As when i try to log into the site, i am surprisingly always getting "FALSE" from Membership.Validateuser (). I goggled it and now i know i am not the alone victim of this irritating bug. Our live site is going to be down...
I have an .aspx page with a couple of textfields. I validate these with jQuery validation plugin when the user clicks the submit button. When the submit button is clicked I also open up a new window, but I only want to open the window if the fields are correctly filled out.How do I stop the window from opening if the fields are not validated?

I have a SQL stored proc that returns a dataset to ASP.NET v3.5 dataset. One of the columns in the dataset is called Attend and is a nullable bit column in the SQL table. The SELECT for that column is this:
CASE WHEN Attend IS NULL THEN -1 ELSE Attend END AS Attend
When I execute the SP in Query Analyzer the row values are returned as they should be - the value for Attend is -1 is some rows, 0 in others, and 1 in others. However, when I debug the C# code and examine the dataset, the Attend column always contains -1.
If I SELECT any other columns or constant values for Attend the results are always correct. It is only the above SELECT of the bit field that is behaving strangely. I suspect it has something to do with the type being bit that is causing this. So to test this I instead selected "CONVERT(int, Attend)" but the behavior is the same.
I have tried using ExecuteDataset to retrieve the data and I have also created a .NET Dataset schema with TableAdapter and DataTable.
I have a function which returns dataset after execution of sql statements
If the dataset retruns rows than he data shld be dislayed in reporting services
Else display no rows avaliable
But currently even if there are no rows as per the given condition, the earlier data gets displayed
Iam confronted with a really weird issue the like of which ive never seen before. I recently developed a web application using ASP.net and launched it for my company, during the bug testing stages everything seemed fine, but once it was actually in production i started getting these weird errors that all stem from it not retrieving the correct rows.
The issue is this, sometimes the queries sent to the back end only return a partial amount of the rows actualyl requested, so if a user has a page loaded thats suppose to return X number of rows, they can sometimes get X - Y number of rows, and upon refreshing the page they get X - Z number of rows, and refreshing the same exact page again they might get X number of rows they were initially suppose to see. I've never seen anything like this before so Iam stumped.
I consulted some of the old developers in the company I used to work for, for assistance but when explaining and showing the problem they too were very confused with the issue.
I have a gridview that has the header row modified in order to add new records; the gridview is bound to a sqldatasource control. In my code behind, i handle the insert in the following manner:
[Code]....
I know the insert is occuring because the new record shows up in the grid after the databind, but the output parameter is not picking up the scope_identity() value...what am i doing wrong with the output parameter?
How come my query returns 0 records?
SELECT WebSiteID, BanDate
FROM tblWebSite
WHERE (BanDate <> NULL)
The BanDate is a date column. There are date times through the table in this column. I just want the ones with a date and ignore the rest.
[Code]....
The following setup seems to work fine on the client side, however when I post back and check Page.IsValid, the value is false. I also looked at mevDate.IsValid and it's false. It seems that setting the CultulreName on the MaskedEditExtender is sufficient to get the MaskedEditValidator to emit the correct JavaScript, but on the server side of things it doesn't work. When I flip CultureName to "en-US" everything works as expected.
I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.
The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.
while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.
for test I tried to create the folder then it says can't find the path...
userFolderName = @"W:/Webs/ASPPages/cropper/uploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried "W:\Webs\ASPPages\cropper\uploads"
DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........
I have a page with a (gridview nested within a gridview) in an UpdatePanel (UpdateMode="Conditional"). The nested gridview drops down when you click on an arrow and then you can click on each subgrid rows command field. The gridviews are loaded from the Page_Load event. When I click on the commandfield in the subgrid the Page_Load fires during the partial page postback. From what I have read this is normal with UpdatePanels. But What I don't understand is why both Page.IsPostBack and ScriptManager.GetCurrent(Page).IsInAsyncPostBack test false after I click on the command field in my grid. I need to stop the rebinding of the gridviews ( which causes the subgrid to collapse ) when the command field is clicked.Also: I am using MasterPages and the <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> is located in my mater page form section.Would anyone have any suggestions how to test if a partial page postback is occuringHere is a link to the page source: http://pastebin.org/153774here is a link to the code behind: http://pastebin.org/153781
View 2 RepliesI'm having trouble with something that is (or should be) fairly straight-forward.
I have a recursive method that traverses an XML file, writing out the element tag names and values.
This is a snippet from the XML file:
[code]
<root>
<all_companies>
<company_group company_group_ID_attr="1">
<company_group_name>Cleaning</company_group_name>
<company_group_ID>1</company_group_ID>
<company company_ID_attr="2">
<name>Bloomburg</name>
<company_ID>2</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>4</employee_ref>
</employee_refs>
</company>
<company company_ID_attr="4">
<name>Morris</name>
<company_ID>4</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>3</employee_ref>
<employee_ref>1</employee_ref>
</employee_refs>
</company>
<company company_ID_attr="7">
<name>Ajax</name>
<company_ID>7</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>4</employee_ref>
<employee_ref>2</employee_ref>
</employee_refs>
</company>
</company_group>
</all_companies>
</root>
[/code]
I use the following XPath expression to access the first <company group> tag:
"root[1]/all_companies[1]/company_group[1]"
On the first call to the recursive method ("swrite_for_select_certain_stuff"),I see with the debugger that I reach the <company_group_name> tag. A recursive call at that point takes me to the text node within the tag ("Cleaning"), but it is a text type node (not an element), so it returns without writing anything to the output stream.
On return from that second call, things go wrong. The Iterator within the while loop returns false for the MoveNext method, when it should have moved to the <company_group_ID> tag (or so I think it should).
Am I missing something here?
